Never be ashamed of madness, instead be ashamed of people that are ashamed of madness. Without a little bit of insanity, we would have never had the Theory of Relativity, electricity, airplanes, cars or your beloved iPhone. Madness got you that.

How can you measure progress if you don't know what it costs and who has paid for it? How can the "market" put a price on things - food, clothes, electricity, running water - when it doesn't take into account the REAL cost of production?

Sometimes things are a change for the better and the worse at the same time, like the internet. Or the electric keyboard. Or pre-chopped garlic. Or the theory of relativity.

But the poetry of that kiss, the wonder of it, the magic that there was in life for hours after it--who can describe that? It is so easy for an Englishman to sneer at these chance collisions of human beings. To the insular cynic and the insular moralist they offer an equal opportunity. It is so easy to talk of "passing emotion," and how to forget how vivid the emotion was ere it passed. Our impulse to sneer, to forget, is at root a good one. We recognize that emotion is not enough, and that men and women are personalities capable of sustained relations, not mere opportunities for an electrical discharge. Yet we rate the impulse too highly. We do not admit that by collisions of this trivial sort the doors of heaven may be shaken open.

She thought of all the things she’d forgotten to be scared of.

Reality is approximately as dependable as a politician’s promise... the result is the same: Reality, of the capital “R” variety, has become as relative a thing as the dryness of our respective Martinis. Yet the struggle goes on, the fight continues. Against what? Ultimately, Powers, Principalities, Thrones, and Dominations, often contained in hosts who are themselves victims, prisoners, manipulated men and women.

Chizpurfle infestations explain the puzzling failure of many relatively new Muggle electrical artifacts.

TV came relatively late to the King household, and I’m glad. I am, when you stop to think of it, a member of a fairly select group: the final handful of American novelists who learned to read and write before they learned to eat a daily helping of video bullshit. This might not be important. On the other hand, if you’re just starting out as a writer, you could do worse than strip your television’s electric plug-wire, wrap a spike around it, and then stick it back into the wall. See what blows, and how far. Just an idea.

Two and a half million years ago, when our distant relative Homo habilis was foraging for food across the Tanzanian savannah, a beam of light left the Andromeda Galaxy and began its journey across the Universe. As that light beam raced across space at the speed of light, generations of pre-humans and humans lived and died; whole species evolved and became extinct, until one member of that unbroken lineage, me, happened to gaze up into the sky below the constellation we call Cassiopeia and focus that beam of light onto his retina. A two-and-a-half-billion-year journey ends by creating an electrical impulse in a nerve fibre, triggering a cascade of wonder in a complex organ called the human brain that didn’t exist anywhere in the Universe when the journey began.

Real science is creative, as much so as painting, sculpture, or writing.Beauty, variously defined, is the criterion for art, and likewise a good theory has the elegance, proportion, and simplicity that we find beautiful. Just as the skilled artist omits the extraneous and directs our attention to a unifying concept, so the scientist strives to find a relatively simple order underlying the apparent chaos of perception.

no matter how useful the electricity may be, it needs connections to function

On this material plane, each living being is like a street lantern lamp with a dirty lampshade. The inside flame burns evenly and is of the same quality as all the rest—hence all of us are equal in the absolute sense, the essence, in the quality of our energy. However, some of the lamps are “turned down” and having less light in them, burn fainter, (the beings have a less defined individuality, are less in tune with the universal All which is the same as the Will)—hence all of us are unequal in a relative sense, some of us being more aware (human beings), and others being less aware (animal beings), with small wills and small flames. The lampshades of all are stained with the clutter of the material reality or the physical world. As a result, it is difficult for the light of each lamp to shine through to the outside and it is also difficult to see what is on the other side of the lampshade that represents the external world (a great thick muddy ocean of fog), and hence to “feel” a connection with the other lantern lamps (other beings). The lampshade is the physical body immersed in the ocean of the material world, and the limiting host of senses that it comes with. The dirt of the lampshade results from the cluttering bulk of life experience accumulated without a specific goal or purpose. The dirtier the lampshade, the less connection each soul has to the rest of the universe—and this includes its sense of connection to other beings, its sense of dual presence in the material world and the metaphysical world, and the thin connection line to the wick of fuel or the flow of electricity that resides beyond the material plane and is the universal energy. To remain “lit” each lantern lamp must tap into the universal Source of energy. If the link is weak, depression and-or illness sets in. If the link is strong, life persists. This metaphor to me best illustrates the universe.

It's not about the sex, exactly. It's the other stuff. Here's the truth: I want ths so badly, To the point where it's almost physically painful sometimes. I want Olivia's soft voiced conversations with Evan Schulmeister, where she takes five steps away from us before she even answers the phone. Just to be alone with him. And I want the palpable waves of electric crush energy that radiate off Cassie these days. I want to know what it feels like to have crushes that could conceivably one day turn into boyfriends.

You think of love as dizzy electricity. You think if you aren't in this heightened state, that the relationship is failing. This is a lie, an infection you contracted from popular music and fantasy reels, that doomed all your short romances in the academy, like with poor Sri. The bonded support you and Kodiak feel for each other isn't about skin skin skin, though it's related to that. It isn't the heat of his body against yours at the bottom of the water tank. Instead, it's the fact that you two are together at the bottom of the water tank.

The terms masculine and feminine are used symmetrically only as a matter of form, as on legal papers. In actuality the relation of the two sexes is not quite like that of two electrical poles, for man represents both the positive and the neutral, as is indicated by the common use of man to designate human beings in general ; whereas woman represents only the negative, defined by limiting criteria, without reciprocity.

The truth, dear reader, is that I was as ready for him as any filly ready for the stud. My blood thrummed whenever he came near, the air crackling between us like one of Galvani’s electrical experiments. It was a mercy that we had not been alone in our train compartment on the journey back to London; otherwise, I suspect the urgent swaying of the conveyance would have proven too much for my increasingly limited self-control.

Modern elevators are strange and complex entities. The ancient electric winch and “maximum-capacity-eight-persons" jobs bear as much relation to a Sirius Cybernetics Corporation Happy Vertical People Transporter as a packet of mixed nuts does to the entire west wing of the Sirian State Mental Hospital. This is because they operate on the curious principle of “defocused temporal perception.” In other words they have the capacity to see dimly into the immediate future, which enables the elevator to be on the right floor to pick you up even before you knew you wanted it, thus eliminating all the tedious chatting, relaxing and making friends that people were previously forced to do while waiting for elevators. Not unnaturally, many elevators imbued with intelligence and precognition became terribly frustrated with the mindless business of going up and down, up and down, experimented briefly with the notion of going sideways, as a sort of existential protest, demanded participation in the decision-making process and finally took to squatting in basements sulking. An impoverished hitchhiker visiting any planets in the Sirius star system these days can pick up easy money working as a counselor for neurotic elevators.

Buber wrote, “When two people relate to each other authentically and humanly, God is the electricity that surges between them.

What Disneyland proposes is a technique of abbreviated shorthand culture for the masses, a mindless thrill, like an electric shock, that insists at the same time on the recipient's rich psychic relation to his country's history and language and literature. In a forthcoming time of highly governed masses in an overpopulated world, this technique may be extremely useful both as a substitute for education and, eventually, as a substitute for experience.

And then—some visionary, through some accident— —accident, Mahavira?— —through some quirk of metabolism, through some drug perhaps, has his doors of perception opened for an instant and he almost sees—presque vu!—the entire being and he knows for the first time that there is a whole … other pattern here … Each moment in his life is only minutely related to the cause-and-effect chain within his little molecular world. Each moment, if he could only analyze it, reveals the entire pattern of the motion of the

All the experiments led to one unifying conclusion: The overall structure, the shape, the pattern, of any animal is as real a part of its body as are its cells, heart, limbs, or teeth. Living things are called organisms because of the overriding importance of organization, and each part of the pattern somehow contains the information as to what it is in relation to the whole. The ability of this pattern to maintain itself reaches its height in the newts, mud puppies, and other amphibians collectively called salamanders.

To the insular cynic and the insular moralist they offer an equal opportunity. It is so easy to talk of “passing emotion,” and to forget how vivid the emotion was ere it passed.

Yet we rate the impulse too highly. We do not admit that by collisions of this trivial sort the doors of heaven may be shaken open.

My laboratory is a place where I write. I have become proficient at producing a rare species of prose capable of distilling ten years of work by five people into six published pages, written in a language that very few people can read and that no one ever speaks. This writing relates the details of my work with the precision of a laser scalpel, but its streamlined beauty is a type of artifice, a size-zero mannequin designed to showcase the glory of a dress that would be much less perfect on any real person. My papers do not display the footnotes that they have earned, the table of data that required painstaking months to redo when a graduate student quit, sneering on her way out that she didn’t want a life like mine. The paragraph that took five hours to write while riding on a plane, stunned with grief, flying to a funeral that I couldn’t believe was happening. The early draft that my toddler covered in crayon and applesauce while it was still warm from the printer. Although my publications contain meticulous details of the plants that did grow, the runs that went smoothly, and the data that materialized, they perpetrate a disrespectful amnesia against the entire gardens that rotted in fungus and dismay, the electrical signals that refused to stabilize, and the printer ink cartridges that we secured late at night through nefarious means. I

An I-it relationship is basically what we create when we are in transactions with people whom we treat like objects - people who are simply there to serve us or complete a task. I-you relationships are characterized by human connection and empathy. Buber wrote, "When two people relate to each other authentically and humanly, God is the electricity that surges between them." After spending a decade studying belonging, authenticity, and shame, I can say for certain that we are hardwired for connection - emotionally, physically, and spiritually.

Working simultaneously, though seemingly without a conscience, was Dr. Ewen Cameron, whose base was a laboratory in Canada's McGill University, in Montreal. Since his death in 1967, the history of his work for both himself and the CIA has become known. He was interested in 'terminal' experiments and regularly received relatively small stipends (never more than $20,000) from the American CIA order to conduct his work. He explored electroshock in ways that offered such high risk of permanent brain damage that other researchers would not try them. He immersed subjects in sensory deprivation tanks for weeks at a time, though often claiming that they were immersed for only a matter of hours. He seemed to fancy himself a pure scientist, a man who would do anything to learn the outcome. The fact that some people died as a result of his research, while others went insane and still others, including the wife of a member of Canada's Parliament, had psychological problems for many years afterwards, was not a concern to the doctor or those who employed him. What mattered was that by the time Cheryl and Lynn Hersha were placed in the programme, the intelligence community had learned how to use electroshock techniques to control the mind. And so, like her sister, Lynn was strapped to a chair and wired for electric shock. The experience was different for Lynn, though the sexual component remained present to lesser degree...

The unsolved problems of the physical world now seem even more formidable than those solved in the twentieth century. Though in application it works splendidly, we do not even understand the physical meaning of quantum mechanics, much less how it might be united with general relativity. We don't know why the dimensionless constants (ratios of masses of elementary particles, ratios of strength of gravitational to electric forces, fine structure constant, etc.) have the values they do, unless we appeal to the implausible anthropic principle, which seems like a regression to Aristotelian teleology.

The subject of one experiment is a rat that receives mild electric shocks (roughly equivalent to the static shock you might get from scuffing your foot on a carpet). Over a series of these, the rat develops a prolonged stress-response: its heart rate and glucocorticoid secretion rate go up, for example. For convenience, we can express the long-term consequences by how likely the rat is to get an ulcer, and in this situation, the probability soars. In the next room, a different rat gets the same series of shocks—identical pattern and intensity; its allostatic balance is challenged to exactly the same extent. But this time, whenever the rat gets a shock, it can run over to a bar of wood and gnaw on it. The rat in this situation is far less likely to get an ulcer. You have given it an outlet for frustration. Other types of outlets work as well—let the stressed rat eat something, drink water, or sprint on a running wheel, and it is less likely to develop an ulcer.

Primarily, which is very notable and curious, I observe that men of business rarely know the meaning of the word 'rich'. At least, if they know, they do not in their reasoning allow for the fact, that it is a relative word, implying its opposite 'poor' as positively as the word 'north' implies its opposite 'south'. Men nearly always speak and write as if riches were absolute, and it were possible, by following certain scientific precepts, for everybody to be rich. Whereas riches are a power like that electricity, acting only through inequalities or negations of itself. The force of the guinea you have in your pockets depends wholly on the default of a guinea in your neighbour's pocket. If he did not want it, it would be of no use to you; the degree of power it possesses depends accurately upon the need or desire he has for it,— and the art of making yourself rich, in the ordinary mercantile economist's sense, is therefore equally and necessarily the art of keeping your neighbour poor.

So the much criticized food subsidy and employment guarantee for the poor and the unemployed cost about 1.14 per cent of GDP, whereas the cost of subsidizing electricity, fuel and fertilizers for the relatively better off is minimally 2.63 per cent, more than twice what is allocated to feed the poor and provide employment to the unemployed.

A full explanation of this is beyond the scope of this book, suffice to say that Einstein was forced into this bold move primarily because Maxwell’s equations for electricity and magnetism were incompatible with Newton’s 200-year-old laws of motion. Einstein abandoned the Newtonian ideas of space and time as separate entities and merged them. In Einstein’s theory there is a special speed built into the structure of spacetime itself that everyone must agree on, irrespective of how they are moving relative to each other. This special speed is a universal constant of nature that will always be measured as precisely 299,792,458 metres (983,571,503 feet) per second, at all times and all places in the Universe, no matter what they are doing. This

What we found was that when people were pursuing leisure activities that were expensive in terms of the outside resources required—activities that demanded expensive equipment, or electricity, or other forms of energy measured in BTUs, such as power boating, driving, or watching television—they were significantly less happy than when involved in inexpensive leisure. People were happiest when they were just talking to one another, when they gardened, knitted, or were involved in a hobby; all of these activities require few material resources, but they demand a relatively high investment of psychic energy. Leisure that uses up external resources, however, often requires less attention, and as a consequence it generally provides less memorable rewards.

To give my characters a real, or at least a convincing, life demanded more space. Did giving them a domestic dimension mean pressing the pause button in order to relate the dull routines of mortgages, electric bills, children’s ailments and traffic jams? No, that is not the way to treat your readers unless you just don’t care about them; and in that case you should be writing literary novels.

During a long heart-to-heart talk, as they ramble through the country lanes near Bredon Hill, his father muses upon the old meaning of ‘pagan’ – ‘belonging to the village’. ‘The village is sneered at as something petty. Petty it can be. Yet it works – the scale is human. People can relate there. Man may yet, in the nick of time, revolt, and save himself. Revolt from the monolith; come back to the village.’ He

World War Two had certainly made everybody very tough. And I became a public relations man for General Electric in Schenectady, New York, and a volunteer fireman in the village of Alplaus, where I bought my first home. My boss there was one of the toughest guys I ever hope to meet. He had been a lieutenant colonel in public relations in Baltimore. While I was in Schenectady he joined the Dutch Reformed Church, which is a very tough church, indeed.

We were to write a short essay on one of the works we read in the course and relate it to our lives. I chose the "Allegory of the Cave" in Plato's Republic. I compared my childhood of growing up in a family of migrant workers with the prisoners who were in a dark cave chained to the floor and facing a blank wall. I wrote that, like the captives, my family and other migrant workers were shackled to the fields day after day, seven days a week, week after week, being paid very little and living in tents or old garages that had dirt floors, no indoor plumbing, no electricity. I described how the daily struggle to simply put food on our tables kept us from breaking the shackles, from turning our lives around. I explained that faith and hope for a better life kept us going. I identified with the prisoner who managed to escape and with his sense of obligation to return to the cave and help others break free.

Everybody is familiar with the standard names of SI units for length (meter, m), mass (kilogram, kg) and time (second, s) but degrees Kelvin (K) rather than Celsius are used to measure temperature; the ampere (A) is the unit of electric current, the mole (mol) quantifies the amount of substance and the candela (cd) the luminous intensity. More than twenty derived units, including all energy-related variables, have special names and symbols, many given in honor of leading scientists and engineers. The unit of force, kgm/s2 (kilogram-meter per second squared), is the newton (N): the application of 1 N can accelerate a mass of one kilogram by one meter per second each second. The unit of energy, the joule (J), is the force of one newton acting over a distance of one meter (kgm2/s2). Power, simply the energy flow per unit of time (kgm2/s3), is measured in watts (W): one watt equals one J/s and, conversely, energy then equals power 3 times, and hence one J is one watt-second.

These facilities were relatively rustic even for this area of the world. Other inns at least had indoor plumbing and electricity. Most even had radios. But not this one. Perhaps it had something to do with the part of town he was in. It was known to the locals as the Nostalgia District, though no one really knew how the area had gotten its name. Did it come about through the feeling that it evoked in its residents and visitors? Or was it due to a lack of modern conveniences? The former certainly seemed less likely than the latter as it seemed doubtful that its long-time residents could continually, over the course of years, manage to be subject to a sense of nostalgia. After all, wouldn’t the perpetual absence of a modern context, eventually, defeat the purpose of evoking such a feeling? In fact, it would seem more appropriate to assume that visitors who spent enough time within the confines of this area were unwittingly apt to live in the past and become nostalgic for the modern day...or even the future.

But TV came relatively late to the King household, and I’m glad.

The gravitational attraction relative to the electrical repulsion between two electrons is 1 divided by 4.17 times ten to the 42nd power! As an example of something , let us consider the time it takes light to go across a proton, 10 to the negative 24 second. If we compare this time with the age of the universe , 2 times 10 to the tenth power years, the answer is 10 to the negative 42nd power. It has about the same number of zeros going off it, so it has been proposed that the gravitational constant is related to the age of the universe.

We're taught to talk about the world as a world of as states conceived as unified, coherent entities. If you study international relations (IR) theory, there's what's called "realist" IR theory, which says there is an anarchic world of states and states pursue their "national interest." It's in large part mythology. There are a few common interests, like we don't want to be destroyed. But, for the most part, people within a nation have very different interests. The interests of the CEO of General Electric and the janitor who cleans his floor are not the same.

Then there occurred to me the 'glucklichste Gedanke meines Lebens,' the happiest thought of my life, in the following form. The gravitational field has only a relative existence in a way similar to the electric field generated by magnetoelectric induction. Because for an observer falling freely from the roof of a house there exists-at least in his immediate surroundings-no gravitational field [his italics]. Indeed, if the observer drops some bodies then these remain relative to him in a state of rest or of uniform motion, independent of their particular chemical or physical nature (in this consideration the air resistance is, of course, ignored). The observer therefore has the right to interpret his state as 'at rest.' Because of this idea, the uncommonly peculiar experimental law that in the gravitational field all bodies fall with the same acceleration attained at once a deep physical meaning. Namely, if there were to exist just one single object that falls in the gravitational field in a way different from all others, then with its help the observer could realize that he is ina gravitational field and is falling in it. If such an object does not exist, however-as experience has shown with great accuracy-then the observer lacks any objective means of perceiving himself as falling in a gravitational field. Rather he has the right to consider his state as one of rest and his environment as field-free relative to gravitation. The experimentally known matter independence of the acceleration of fall is therefore a powerful argument for the fact that the relativity postulate has to be extended to coordinate systems which, relative to each other, are in non-uniform motion.

Franklin was concerning himself more and more with public affairs. He set forth a scheme for an Academy, which was taken up later and finally developed into the University of Pennsylvania; and he founded an "American Philosophical Society" for the purpose of enabling scientific men to communicate their discoveries to one another. He himself had already begun his electrical researches, which, with other scientific inquiries, he called on in the intervals of money-making and politics to the end of his life. In 1748 he sold his business in order to get leisure for study, having now acquired comparative wealth; and in a few years he had made discoveries that gave him a reputation with the learned throughout Europe. In politics he proved very able both as an administrator and as a controversialist; but his record as an office-holder is stained by the use he made of his position to advance his relatives. His most notable service in home politics was his reform of the postal system; but his fame as a statesman rests chiefly on his services in connection with the relations of the Colonies with Great Britain, and later with France.

Diallo, a West African immigrant in New York, matched a description of a rapist. Four white officers questioned him, and when the unarmed Diallo started to pull out his wallet, they decided it was a gun and fired forty-one shots. The underlying neurobiology concerns “event-related potentials” (ERPs), which are stimulus-induced changes in electrical activity of the brain (as assessed by EEG—electroencephalography). Threatening faces produce a distinctive change (called the P200 component) in the ERP waveform in under two hundred milliseconds. Among white subjects, viewing someone black evokes a stronger P200 waveform than viewing someone white, regardless of whether the person is armed. Then, a few milliseconds later, a second, inhibitory waveform (the N200 component) appears, originating from the frontal cortex—“Let’s think a sec about what we’re seeing before we shoot.” Viewing a black individual evokes less of an N200 waveform than does seeing someone white. The greater the P200/N200 ratio (i.e., the greater the ratio of I’m-feeling-threatened to Hold-on-a-sec), the greater the likelihood of shooting an unarmed black individual.

The run-down test was originally scheduled for the afternoon of the 25th, but Chief Engineer Nikolai Fomin was asked by Kiev’s national grid controller to delay it until after the evening peak electricity consumption period had ended.94 The afternoon staff had been briefed on the test and knew exactly what to do, but their shift ended and they went home. Evening staff took over, but then they too left, leaving the relatively inexperienced night crew - who had never conducted a test before - the responsibility of starting a test they were not prepared for and had not anticipated doing.

The human brain acts as a mere transducer of electrical energy. Our senses are on full alert when we are in danger. In contrast, when we are relatively safe and secure, our senses tend to slumber, making the world pass by analogous to a fuzzy dream composed of meaningless impressions. Inner turmoil causes energy surges in the brain. A spontaneously convulsing brain is an artistic brain. It is useful to write whenever one is in pain or feeling particularly introspective. Trauma awakens us from a sedated life. A clicked on brain displays greater sensitivity to the synesthetic perceptions that fill life with a diversity of sounds, colors, tastes, tactile feelings, and odors.

by knowledge the privilege to BE! His insight refines him. The beauty of nature shines in his own breast. Man is greater that he can see this, and the universe less, because Time and Space relations vanish as laws are known. Here again we are impressed and even daunted by the immense Universe to be explored. "What we know, is a point to what we do not know." Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted. Passing by many particulars of the discipline of nature, we must not omit to specify two. The exercise of the Will or the

Everywhere we look in the realm of nature we find polarities, such as electrical and magnetic polarities. These can, if we like, be modeled in terms of gender; for example, positive electrical charge is associated with dense, relative immobile atomic nuclei, a bit like eggs; negative charge is associated with the smaller electrons, moving in swarms, a bit like sperm. But sexual gender is only one of many kinds of natural polarity and only one of the ways we experience polarity in our own lives. Others include the polarities of up and down, in and out, front and back, right and left, past and future, sleeping and waking, friend and foe, sweet and sour, hot and cold, pleasure and pain, good and bad.

The power of the deductive network produced in physics has been illustrated in a delightful article by Victor F. Weisskopf. He begins by taking the magnitudes of six physical constants known by measurement: the mass of the proton, the mass and electric charge of the electron, the light velocity, Newton's gravitational constant, and the quantum of action of Planck. He adds three of four fundamental laws (e.g., de Broglie's relations connecting particle momentum and particle energy with the wavelength and frequency, and the Pauli exclusion principle), and shows that one can then derive a host of different, apparently quite unconnected, facts that happen to be known to us by observation separately ....

Finance is concerned with the relations between the values of securities and their risk, and with the behavior of those values. It aspires to be a practical, like physics or chemistry or electrical engineering. As John Maynard Keynes once remarked about economics, “If economists could manage to get themselves thought of as humble, competent people on a level with dentists, that would be splendid.” Dentists rely on science, engineering, empirical knowledge, and heuristics, and there are no theorems in dentistry. Similarly, one would hope that nance would be concerned with laws rather than theorems, with behavior rather than assumptions. One doesn’t seriously describe the behavior of a market with theorems.

Scientists, however, are still believed to be objective. No study of the lives of the great scientists will confirm this. They were as passionate, and hence as prejudiced, as any assembly of great painters or great musicians. It was not just the Church but also the established astronomers of the time who condemned Galileo. The majority of physicists rejected Einstein’s Special Relativity Theory in 1905. Einstein himself would not accept anything in quantum theory after 1920 no matter how many experiments supported it. Edison’s commitment to direct current (DC) electrical generators led him to insist alternating current (AC) generators were unsafe for years after their safety had been proven to everyone else.* ~•~

In using the present in order to reveal the past, we assume that the forces in the world are essentially the same through all time; for these forces are based on the very nature of matter, and could not have changed. The ocean has always had its waves, and those waves have always acted in the same manner. Running water on the land has ever had the same power of wear and transportation and mathematical value to its force. The laws of chemistry, heat, electricity, and mechanics have been the same through time. The plan of living structures has been fundamentally one, for the whole series belongs to one system, as much almost as the parts of an animal to the one body; and the relations of life to light and heat, and to the atmosphere, have ever been the same as now.

Facebook’s “Like” feature, some version of which now exists on every platform, is the equivalent of a car battery hooked up to that sociometer. It gives whoever controls the electric jolts tremendous power over our behavior. It’s not just that “likes” provide the social validation we spend so much of our energy pursuing; it’s that they offer it at an immediacy and scale heretofore unknown in the human experience. Off-line, explicit validation is relatively infrequent. Even rarer is hearing it announced publicly, which is the most powerful form of approval because it conveys our value to the broader community. When’s the last time fifty, sixty, seventy people publicly applauded you off-line? Maybe once every few years—if ever? On social media, it’s a normal morning. Further,

Octopuses and their relatives have what Woods Hole researcher Roger Hanlon calls electric skin. For its color palette, the octopus uses three layers of three different types of cells near the skin’s surface—all controlled in different ways. The deepest layer, containing the white leucophores, passively reflects background light. This process appears to involve no muscles or nerves. The middle layer contains the tiny iridophores, each 100 microns across. These also reflect light, including polarized light (which humans can’t see, but a number of octopuses’ predators, including birds, do). The iridophores create an array of glittering greens, blues, golds, and pinks. Some of these little organs seem to be passive, but other iridophores appear to be controlled by the nervous system. They are associated with the neurotransmitter acetylcholine, the first neurotransmitter to be identified in any animal. Acetylcholine helps with contraction of muscles; in humans, it is also important in memory, learning, and REM sleep. In octopuses, more of it “turns on” the greens and blues; less creates pinks and golds. The topmost layer of the octopus’s skin contains chromatophores, tiny sacks of yellow, red, brown, and black pigment, each in an elastic container that can be opened or closed to reveal more or less color. Camouflaging the eye alone—with a variety of patterns including a bar, a bandit’s mask, and a starburst pattern—can involve as many as 5 million chromatophores. Each chromatophore is regulated via an array of nerves and muscles, all under the octopus’s voluntary control.

For example, the force of electricity between two charged objects looks just like the law of gravitation: the force of electricity is a constant, with a minus sign, times the product of the charges, and varies inversely as the square of the distance. It is in the opposite direction-likes repel. But is it still not very remarkable that the two laws involve the same function of distance? Perhaps gravitation and electricity are much more closely related than we think. Many attempts have been made to unify them; the so called unified-field theory is only a very elegant attempt to combine electricity and gravitation; but, in comparing gravitation and electricity , the most interesting thing is the relative strengths of the forces. Any theory that contains them both must also deduce how strong the gravity is.

Since the beginning of the electric grid, utilities have placed most power plants close to America’s rapidly growing cities, because it was relatively easy to use railroads and pipelines to ship fossil fuels from wherever they were extracted to the power plants where they’d be burned to make electricity. As a result, America’s power grid relies on railroads and pipelines to move fuels over long distances to power plants, and then on transmission lines to move electricity over short distances to the cities that need it. That model doesn’t work with solar and wind. You can’t ship sunlight in a railcar to some power plant; it has to be converted to electricity on the spot. But most of America’s sunlight supply is in the Southwest, and most of our wind is in the Great Plains, far from many major urban areas.

At the telegraph office, while drafting my telegram with all the excitement of a man burning with hope, I noted how much less helpless I was now than in my childhood and in relation to Mlle d’Éporcheville than to Gilberte. I need do no more than take the simple trouble to write my telegram, and the clerk had only to accept it, for the swiftest of electric communications networks to transmit it across the length and breadth of France, right down to the Mediterranean coast. Robert would bring his whole libertine past to bear on identifying the person whom I had just encountered, would place it at the disposal of the fiction that I was starting to sketch and which I need not even worry about any more, for the reply would be bound to bring my romance to a conclusion in one way or another before twenty-four hours had elapsed.

Nobody is ever made happy by winning the lottery, buying a house, getting a promotion or even finding true love. People are made happy by one thing and one thing only – pleasant sensations in their bodies. A person who just won the lottery or found new love and jumps from joy is not really reacting to the money or the lover. She is reacting to various hormones coursing through her bloodstream and to the storm of electric signals flashing between different parts of her brain. Unfortunately for all hopes of creating heaven on earth, our internal biochemical system seems to be programmed to keep happiness levels relatively constant. There's no natural selection for happiness as such - a happy hermit's genetic line will go extinct as the genes of a pair of anxious parents get carried on to the next generation. Happiness and misery play a role in evolution only to the extent that they encourage or discourage survival and reproduction. Perhaps it's not surprising, then, that evolution has moulded us to be neither too miserable nor too happy. It enables us to enjoy a momentary rush of pleasant sensations, but these never last for ever. Sooner of later they subside and give place to unpleasant sensations. (...) Some scholars compare human biochemistry to an air-conditioning system that keeps the temperature constant, come heatwave or snowstorm. Events might momentarily change the temperature, but the air-conditioning system always returns the temperature to the same set point. Some air-conditioning systems are set at twenty-five degrees Celsius. Others are set at twenty degrees. Human happiness conditioning systems also differ from person to person. On a scale from one to ten, some people are born with a cheerful biochemical system that allows their mood to swing between levels six and ten, stabilising with time at eight. Such a person is quite happy even if she lives in an alienating big city, loses all her money in a stock-exchange crash and is diagnosed with diabetes. Other people are cursed with a gloomy biochemistry that swings between three and seven and stabilises at five. Such an unhappy person remains depressed even if she enjoys the support of a tight-knit community, wins millions in the lottery and is as healthy as an Olympic athlete (...) incapable of experiencing anything beyond level seven happiness. Her brain is simply not built for exhilaration, come what may. (...) Buying cars and writing novels do not change our biochemistry. They can startle it for a fleeting moment, but it is soon back to the set point.

Nevertheless, it is interesting to note that almost the entire first two sections of his relativity paper deal directly and in vivid practical detail (in a manner so different from the writings of, say, Lorentz and Maxwell) with the two real-world technological phenomena he knew best. He writes about the generation of “electric currents of the same magnitude” due to the “equality of relative motion” of coils and magnets, and the use of “a light signal” to make sure that “two clocks are synchronous.” As Einstein himself stated, his time in the patent office “stimulated me to see the physical ramifications of theoretical concepts.”51 And Alexander Moszkowski, who compiled a book in 1921 based on conversations with Einstein, noted that Einstein believed there was “a definite connection between the knowledge acquired at the patent office and the theoretical results.

To Daniel the words Father and Mother had the altar-fire in them; and the thought of all closest relations of our nature held still something of the mystic power which had made his neck and ears burn in boyhood. The average man may regard this sensibility on the question of birth as preposterous and hardly credible; but with the utmost respect for his knowledge as the rock from which all other knowledge is hewn, it must be admitted that many well-proved facts are dark to the average man, even concerning the action of his own heart and the structure of his own retina. A century ago he and all his forefathers had not had the slightest notion of that electric discharge by means of which they had all wagged their tongues mistakenly; any more than they were awake to the secluded anguish of exceptional sensitiveness into which many a carelessly-begotten child of man is born.

Cordelia – “Why so rough?” Aral – “It’s very poor. It was the town center during the time Isolation. And it hasn’t been touched by renovation, minimal water, no electricity choked with refuse.” “Mostly human,” added Peoter tartly. “Poor?” Asked Cordelia bewildered. “No electricity? How can it be on the comm network?” “It’s not of course,” answered Vorkosigan. “Then how can anyone get their schooling?” Cordelia “They don’t.” Cordelia stared. “I don’t understand, how do they get their jobs?” “A few escape to the service, the rest prey on each other mostly.” Vorkosigan regarded her face uneasily. “Have you no poverty on Beta colony?” “Poverty? Well some people have more money than others, but no comm consuls…?” Vorkosigan was diverted from his interrogation. “Is not owning a comm consul the lowest standard of living you can imagine?” He said in wonder. “It’s the first article in the constitution! ‘Access to information shall not be abridged.’” “Cordelia, these people barely have access to food, clothing and shelter. They have a few rags and cooking pots and squat in buildings that aren’t economical to repair or tear down yet with the wind whistling through the walls.” “No air conditioning?” “No heat in the winter is a bigger problem here.” “I suppose so. You people don’t really have summer. How do they call for help when they are sick or hurt?” “What help?” Vorkosigan was growing grim. “If they’re sick they either get well or die.” “Die if we’re lucking” muttered Veoter. “You’re not joking.” She stared back and forth between the pair of them. “Why, think of all the geniuses you must missing!” “I doubt we must be missing very many from the Caravanceri.” Said Peoter dryly. “Why not? They have the same genetic compliment as you.” Cordelia pointed out the – to her -obvious. The Count went rigid. “My dear girl, they most certainly do not. My family has been Vor for nine generations.” Cordelia raised her eyebrows. “How do you know if you didn’t have the gene-typing until 80 years ago?” Both the guard commander and the footman were acquiring peculiar stuffed expressions. The footman bit his lip. “Besides,” she pointed out reasonably, “If you Vor got around half as much as those histories I’ve been reading imply. 90% of the people on this planet must have Vor blood by now. Who knows who your relatives are on your father’s side. Vorkosigan bit his napkin absently. His eyes gone crinkly with much the same expression as the footman and muttered, “Cordelia, you really can’t sit at the breakfast table and imply my ancestors were bastards. It’s a mortal insult here.” “Where should I sit? Oh I’ll never understand.

There is in Moscow a great curiosity for things American, and a great sympathy for things Negro. So, being both an American and a Negro, I am met everywhere with friendly questions from children and adults as to how we live at home. Is there really a crisis, with people hungry and ragged when there are in America so many factories, so much technique, so much wheat, and cotton and livestock? How can that be? Do they actually kill people in electric chairs? Actually lynch Negroes? Why? The children in the Moscow streets, wise little city children, will oft times gather around you if you are waiting for a streetcar, or looking into a shop window. They will take your hand and ask you about the Scottsboro boys, or if you like the Soviet Union and are going to stay forever. Sometimes as you pass a group of children playing, they will stop and exclaim, "Negro!" But in wonder and surprise a long ways from the insulting derision of the word "Nigger" in the mouths of America's white children. Here, the youth in the schools are taught to respect all races.

Since I saw them pictures a while back on the front page of The New York Times of that police dog in Birmingham biting a young black student in the stomach, I have ceased to like white folks," said Simple. "As bad as Birmingham is," I said, "surely you do not blame white people in New York or Detroit or San Francisco for that Alabama dog." "I do," said Simple, "because white folks is in the majority every-where. They control the government in Washington, and if they let such doings go on in this American country, such as has been going on in Alabama and Mississippi, I blame them all. If white folks was bit by police dogs and prodded with electric rods, you can bet your bottom dollar something would be done about it—and quick—before you could say Jackie Robinson." "You are no doubt right," I said, "but as long as they themselves are not bitten by dogs and prodded by electric rods and denied the right to march or to vote, most white folks in the North will do very little to help Southern Negroes." "And I will do very little toward loving them," said Simple.

Einstein’s approach to general relativity again showed how his mind tended to work: • He was disquieted when there were two seemingly unrelated theories for the same observable phenomenon. That had been the case with the moving coil or moving magnet producing the same observable electric current, which he resolved with the special theory of relativity. Now it was the case with the differing definitions of inertial mass and gravitational mass, which he began to resolve by building on the equivalence principle. • He was likewise uncomfortable when a theory made distinctions that could not be observed in nature. That had been the case with observers in uniform motion: there was no way of determining who was at rest and who was in motion. Now it was also, apparently, the case for observers in accelerated motion: there was no way of telling who was accelerating and who was in a gravitational field. • He was eager to generalize theories rather than settling for having them restricted to a special case. There should not, he felt, be one set of principles for the special case of constant-velocity motion and a different set for all other types of motion. His life was a constant quest for unifying theories.

She hadn't gone back in time. The idea was silly. Or had she? Had she knocked on the door of her home to see a younger version of herself answer; had there been a mutual shock of recognition (as the younger Rebecca realized that, yes, her husband's work was due to be a success, that he was not wasting his time chasing rainbows and tilting at windmills); had she slipped her arm into that of her past self (feeling a slight electric tingle as skin touched skin and a taste in her mouth as if she'd touched a nine-volt battery to her tongue) and said, We need to to talk? Had she sat in a coffee shop, conversing with a woman who everyone assumed was related to her in some way—Oh my god you two are so cute, you're mother and daughter but you look like sisters? Had she made some kind of idle remark overheard by a man on his way to spend two weeks' vacation in North Dakota; had that comment convinced that man to settle there permanently instead, and to contact those who had political sympathies similar to his own? Had that unknown man begun the slow process of taking over the state by placing his allies in the local governments if he could? Had that strategy failed, leaving brute force as a regrettable last resort?

When we put an electron in an electric field, we say it is "pulled." We then have two rules: (a) charges make a field, and (b) charges in fields have forces on them and move. The reason for this will be- come clear when we discuss the following phenomena: If we were to charge a body, say a comb, electrically, and then place a charged piece of paper at a distance and move the comb back and forth, the paper will respond by always pointing to the comb. If we shake it faster, it will be discovered that the paper is a little behind, there is a delay in the action. (At the first stage, when we move the comb rather slowly, we find a complication which is magnetism. Magnetic influences have to do with charges in relative motion, so magnetic forces and electric forces can really be attributed to one field, as two different aspects of exactly the same thing. A changing electric field cannot exist without magnetism.) If we move the charged paper farther out, the delay is greater. Then an interesting thing is observed. Although the forces between two charged objects should go inversely as the square of the distance, it is found, when we shake a charge, that the influence extends very much farther out than we would guess at first sight. That is, the effect falls off more slowly than the inverse square.

Because of the extreme heat fission generates, the reactor core must be kept cool at all costs. This is particularly important with an RBMK, which operates at an, “astonishingly high temperature,” relative to other reactor types, of 500°C with hotspots of up to 700°C, according to British nuclear expert Dr. Eric Voice. A typical PWR has an operating temperature of about 275°C. A few different kinds of coolant are used in different reactors, from gas to air to liquid metal to salt, but Chernobyl’s uses the same as most other reactors: light water, meaning it is just regular water. The plant was originally going to be fitted with gas-cooled reactors, but this was eventually changed because of a shortage of the necessary equipment.75 Water is pumped into the bottom of the reactor at high pressure (1000psi, or 65 atmospheres), where it boils and passes up, out of the reactor and through a condensator that separates steam from water. All remaining water is pushed through another pump and fed back into the reactor. The steam, meanwhile, enters a steam turbine, which turns and generates electricity. Each RBMK reactor produces 5,800 tons of steam per hour.76 Having passed through this turbogenerator, the steam is condensed back into water and fed back to the pumps, where it begins its cycle again.

Finally, if we add to these observations the remark that Marx owes to the bourgeois economists the idea, which he claims exclusively as his own, of the part played by industrial production in the development of humanity, and that he took the essentials of his theory of work-value from Ricardo, an economist of the bourgeois industrial revolution, our right to say that his prophecy is bourgeois in content will doubtless be recognized. These comparisons only aim to show that Marx, instead of being, as the fanatical Marxists of our day would have it, the beginning and the end of the prophecy, participates on the contrary in human nature: he is an heir before he is a pioneer. His doctrine, which he wanted to be a realist doctrine, actually was realistic during the period of the religion of science, of Darwinian evolutionism, of the steam engine and the textile industry. A hundred years later, science encounters relativity, uncertainty, and chance; the economy must take into account electricity, metallurgy, and atomic production. The inability of pure Marxism to assimilate these successive discoveries was shared by the bourgeois optimism of Marx's time. It renders ridiculous the Marxist pretension of maintaining that truths one hundred years old are unalterable without ceasing to be scientific. Nineteenth-century Messianism, whether it is revolutionary or bourgeois, has not resisted the successive developments of this science and this history, which to different degrees they have deified.

What is the vril?” I asked. Therewith Zee began to enter into an explanation of which I understood very little, for there is no word in any language I know which is an exact synonym for vril. I should call it electricity, except that it comprehends in its manifold branches other forces of nature, to which, in our scientific nomenclature, differing names are assigned, such as magnetism, galvanism, &c. These people consider that in vril they have arrived at the unity in natural energetic agencies, which has been conjectured by many philosophers above ground, and which Faraday thus intimates under the more cautious term of correlation:— “I have long held an opinion,” says that illustrious experimentalist, “almost amounting to a conviction, in common, I believe, with many other lovers of natural knowledge, that the various forms under which the forces of matter are made manifest, have one common origin; or, in other words, are so directly related and mutually dependent that they are convertible, as it were into one another, and possess equivalents of power in their action. These subterranean philosophers assert that by one operation of vril, which Faraday would perhaps call ‘atmospheric magnetism,’ they can influence the variations of temperature—in plain words, the weather; that by operations, akin to those ascribed to mesmerism, electro-biology, odic force, &c., but applied scientifically, through vril conductors, they can exercise influence over minds, and bodies animal and vegetable, to an extent not surpassed in the romances of our mystics. To all such agencies they give the common name of vril.

A second element in the creation of commercial value is scarcity, the separation of people from whatever they might want or need. In artificial environments, where humans are separated from the sources of their survival, everything obtains a condition of relative scarcity and therefore value. There is the old story of the native living on a Pacific island, relaxing in a house on the beach, picking fruit from the tree and spearing fish in the water. A businessman arrives on the island, buys all the land, cuts down the trees and builds a factory. Then he hires the native to work in it for money so that someday the native can afford canned fruit and fish from the mainland, a nice little cinder-block house near the beach with a view of the water, and weekends off to enjoy it. The moment people move off land which has directly supported them, the necessities of life are removed from individual control. The things people could formerly produce for their survival must now be paid for. You may be living on the exact spot where a fruit tree once fed people. Now the fruit comes from five hundred miles away and costs thirty-five cents apiece. It is in the separation that the opportunity for profit resides. When the basic necessities are not scarce—in those places where food is still wild and abundant, for example—economic value can only be applied to new items. Candy bars, bottled or chemical milk, canned tuna, electrical appliances and CocaCola have all been intensively marketed in countries new to the market system. Because these products hadn’t existed in those places before, they are automatically relatively scarce and potentially valuable.

We also find *physics*, in the widest sense of the word, concerned with the explanation of phenomena in the world; but it lies already in the nature of the explanations themselves that they cannot be sufficient. *Physics* is unable to stand on its own feet, but needs a *metaphysics* on which to support itself, whatever fine airs it may assume towards the latter. For it explains phenomena by something still more unknown than are they, namely by laws of nature resting on forces of nature, one of which is also the vital force. Certainly the whole present condition of all things in the world or in nature must necessarily be capable of explanation from purely physical causes. But such an explanation―supposing one actually succeeded so far as to be able to give it―must always just as necessarily be burdened with two essential imperfections (as it were with two sore points, or like Achilles with the vulnerable heel, or the devil with the cloven foot). On account of these imperfections, everything so explained would still really remain unexplained. The first imperfection is that the *beginning* of the chain of causes and effects that explains everything, in other words, of the connected and continuous changes, can positively *never* be reached, but, just like the limits of the world in space and time, recedes incessantly and *in infinitum*. The second imperfection is that all the efficient causes from which everything is explained always rest on something wholly inexplicable, that is, on the original *qualities* of things and the *natural forces* that make their appearance in them. By virtue of such forces they produce a definite effect, e.g., weight, hardness, impact, elasticity, heat, electricity, chemical forces, and so on, and such forces remain in every given explanation like an unknown quantity, not to be eliminated at all, in an otherwise perfectly solved algebraical equation. Accordingly there is not a fragment of clay, however little its value, that is not entirely composed of inexplicable qualities. Therefore these two inevitable defects in every purely physical, i.e., causal, explanation indicate that such an explanation can be only *relatively* true, and that its whole method and nature cannot be the only, the ultimate and hence sufficient one, in other words, cannot be the method that will ever be able to lead to the satisfactory solution of the difficult riddles of things, and to the true understanding of the world and of existence; but that the *physical* explanation, in general and as such, still requires one that is *metaphysical*, which would furnish the key to all its assumptions, but for that very reason would have to follow quite a different path. The first step to this is that we should bring to distinct consciousness and firmly retain the distinction between the two, that is, the difference between *physics* and *metaphysics*. In general this difference rests on the Kantian distinction between *phenomenon* and *thing-in-itself*. Just because Kant declared the thing-in-itself to be absolutely unknowable, there was, according to him, no *metaphysics* at all, but merely immanent knowledge, in other words mere *physics*, which can always speak only of phenomena, and together with this a critique of reason which aspires to metaphysics." ―from_The World as Will and Representation_. Translated from the German by E. F. J. Payne. In Two Volumes, Volume II, pp. 172-173

Sinyukhin began by cutting one branch from each of a series of tomato plants. Then he took electrical measurements around the wound as each plant healed and sent out a new shoot near the cut. He found a negative current—a stream of electrons—flowing from the wound for the first few days. A similar "current of injury" is emitted from all wounds in animals. During the second week, after a callus had formed over the wound and the new branch had begun to form, the current became stronger and reversed its polarity to positive. The important point wasn't the polarity—the position of the measuring electrode with respect to a reference electrode often determines whether a current registers as positive or negative. Rather, Sinyukhin's work was significant because he found a change in the current that seemed related to reparative growth. Sinyukhin found a direct correlation between these orderly electrical events and biochemical changes: As the positive current increased,cells in the area more than doubled their metabolic rate, also becoming more acidic and producing more vitamin C than before. Sinyukhin then applied extra current, using small batteries, to a group of newly lopped plants, augmenting the regeneration current.These battery-assisted plants restored their branches up to three times faster than the control plants. The currents were very small—only 2 to 3 microamperes for five days. (An ampere is a standard unit of electric current, and a microampere is one millionth of an ampere.) Larger amounts of electricity killed the cells and had no growth-enhancing effect. Moreover, the polarity had to match that normally found in the plant. When Sinyukhin used current of the opposite polarity, nullifying the plant's own current, restitution was delayed by two or three weeks.

Modern electrical power distribution technology is largely the fruit of the labors of two men—Thomas Edison and Nikola Tesla. Compared with Edison, Tesla is relatively unknown, yet he invented the alternating electric current generation and distribution system that supplanted Edison's direct current technology and that is the system currently in use today. Tesla also had a vision of delivering electricity to the world that was revolutionary and unique. If his research had come to fruition, the technological landscape would be entirely different than it is today. Power lines and the insulated towers that carry them over thousands of country and city miles would not distract our view. Tesla believed that by using the electrical potential of the Earth, it would be possible to transmit electricity through the Earth and the atmosphere without using wires. With suitable receiving devices, the electricity could be used in remote parts of the planet. Along with the transmission of electricity, Tesla proposed a system of global communication, following an inspired realization that, to electricity, the Earth was nothing more than a small, round metal ball. [...] With $150,000 in financial support from J. Pierpont Morgan and other backers, Tesla built a radio transmission tower at Wardenclyffe, Long Island, that promised—along with other less widely popular benefits—to provide communication to people in the far corners of the world who needed no more than a handheld receiver to utilize it. In 1900, Italian scientist Guglielmo Marconi successfully transmitted the letter "S" from Cornwall, England, to Newfoundland and precluded Tesla's dream of commercial success for transatlantic communication. Because Marconi's equipment was less costly than Tesla's Wardenclyffe tower facility, J. P. Morgan withdrew his support. Moreover, Morgan was not impressed with Tesla's pleas for continuing the research on the wireless transmission of electrical power. Perhaps he and other investors withdrew their support because they were already reaping financial returns from those power systems both in place and under development. After all, it would not have been possible to put a meter on Tesla's technology—so any investor could not charge for the electricity!

It occurred to me, not for the first time, how much simpler our lives would be if we could date each other. That delousing kit cost eleven dollars! “Do you ever think it would be easier if we could go out with girls?” I said aloud. Svetlana didn’t answer right away. “I find most of the lesbians I know a bit intimidating,” she said, finally. “And I don’t really share their aesthetic sense—or they seem not to value aesthetics that much. I just don’t think I’d fit in. Especially since I’m always lusting after boys.” That was something I thought about, too: the physical response I felt to Ivan, the dull electric jolt, some heavy, slow machinery starting to turn in my chest and between my legs. I had never felt those things with relation to a girl. On the other hand, I usually hadn’t felt them in Ivan’s presence, either; it was more when he wasn’t there. And how much was that physical feeling worth? Was it really enough to counterbalance all the disadvantages? You couldn’t just talk to Ivan like he was a normal person; he didn’t hear, or he didn’t understand, or he went off somewhere and you couldn’t find him. Also, all his friends thought I was crazy. Instead of dealing with those people, how much more fun and relaxing it would be to pet Svetlana’s shining golden hair, to tell her how pretty she was and to watch her get more pretty, as she always did when someone complimented her. Her body wanted to be complimented, and I knew just what to tell her, so why couldn’t I? “But girls are more beautiful, and so much easier to sort of negotiate with. And the lust for boys never seems to work out well for me. So it just feels like girls are at least something to think about.” Again, Svetlana didn’t answer right away. “I would feel squeamish with anything beyond kissing and playing with each other’s breasts,” she said after a moment. I realized that I, too, had only been thinking about kissing and playing with each other’s breasts. What else did lesbians even do? Other than oral sex, which was apparently horrible. The way people talked about it on sit-coms: “Does he like . . . deep-sea diving?” You had to be altruistic to do it—a generous lover. That said, oral sex with a boy also seemed likely to be disgusting. Guys themselves seemed to think so. Wasn’t that why they went around yelling “cocksucker” at people who cut them off in traffic? “Do you not feel squeamish when you think about sex with a guy?” I asked. “I do, but it feels exciting. The idea of being penetrated and dominated.

Or think of the tale of the blind men who encounter an elephant for the first time. One wise man, touching the ear of the elephant, declares the elephant is flat and two-dimensional like a fan. Another wise man touches the tail and assumes the elephant is like rope or a one-dimensional string. Another, touching a leg, concludes the elephant is a three-dimensional drum or a cylinder. But actually, if we step back and rise into the third dimension, we can see the elephant as a three-dimensional animal. In the same way, the five different string theories are like the ear, tail, and leg, but we still have yet to reveal the full elephant, M-theory. Holographic Universe As we mentioned, with time new layers have been uncovered in string theory. Soon after M-theory was proposed in 1995, another astonishing discovery was made by Juan Maldacena in 1997. He jolted the entire physics community by showing something that was once considered impossible: that a supersymmetric Yang-Mills theory, which describes the behavior of subatomic particles in four dimensions, was dual, or mathematically equivalent, to a certain string theory in ten dimensions. This sent the physics world into a tizzy. By 2015, there were ten thousand papers that referred to this paper, making it by far the most influential paper in high-energy physics. (Symmetry and duality are related but different. Symmetry arises when we rearrange the components of a single equation and it remains the same. Duality arises when we show that two entirely different theories are actually mathematically equivalent. Remarkably, string theory has both of these highly nontrivial features.) As we saw, Maxwell’s equations have a duality between electric and magnetic fields—that is, the equations remain the same if we reverse the two fields, turning electric fields into magnetic fields. (We can see this mathematically, because the EM equations often contain terms like E2 + B2, which remain the same when we rotate the two fields into each other, like in the Pythagorean theorem). Similarly, there are five distinct string theories in ten dimensions, which can be proven to be dual to each other, so they are really a single eleven-dimensional M-theory in disguise. So remarkably, duality shows that two different theories are actually two aspects of the same theory. Maldacena, however, showed that there was yet another duality between strings in ten dimensions and Yang-Mills theory in four dimensions. This was a totally unexpected development but one that has profound implications. It meant that there were deep, unexpected connections between the gravitational force and the nuclear force defined in totally different dimensions. Usually, dualities can be found between strings in the same dimension. By rearranging the terms describing those strings, for example, we can often change one string theory into another. This creates a web of dualities between different string theories, all defined in the same dimension. But a duality between two objects defined in different dimensions was unheard of.

We tend to be unaware that stars rise and set at all. This is not entirely due to our living in cities ablaze with electric lights which reflect back at us from our fumes, smoke, and artificial haze. When I discussed the stars with a well-known naturalist, I was surprised to learn that even a man such as he, who has spent his entire lifetime observing wildlife and nature, was totally unaware of the movements of the stars. And he is no prisoner of smog-bound cities. He had no inkling, for instance, that the Little Bear could serve as a reliable night clock as it revolves in tight circles around the Pole Star (and acts as a celestial hour-hand at half speed - that is, it takes 24 hours rather than 12 for a single revolution). I wondered what could be wrong. Our modern civilization does not ignore the stars only because most of us can no longer see them. There are definitely deeper reasons. For even if we leave the sulphurous vapours of our Gomorrahs to venture into a natural landscape, the stars do not enter into any of our back-to-nature schemes. They simply have no place in our outlook any more. We look at them, our heads flung back in awe and wonder that they can exist in such profusion. But that is as far as it goes, except for the poets. This is simply a 'gee whiz' reaction. The rise in interest in astrology today does not result in much actual star-gazing. And as for the space programme's impact on our view of the sky, many people will attentively follow the motions of a visible satellite against a backdrop of stars whose positions are absolutely meaningless to them. The ancient mythological figures sketched in the sky were taught us as children to be quaint 'shepherds' fantasies' unworthy of the attention of adult minds. We are interested in the satellite because we made it, but the stars are alien and untouched by human hands - therefore vapid. To such a level has our technological mania, like a bacterial solution in which we have been stewed from birth, reduced us. It is only the integral part of the landscape which can relate to the stars. Man has ceased to be that. He inhabits a world which is more and more his own fantasy. Farmers relate to the skies, as well as sailors, camel caravans, and aerial navigators. For theirs are all integral functions involving the fundamental principle - now all but forgotten - of orientation. But in an almost totally secular and artificial world, orientation is thought to be un- necessary. And the numbers of people in insane asylums or living at home doped on tranquilizers testifies to our aimless, drifting metaphysic. And to our having forgotten orientation either to seasons (except to turn on the air- conditioning if we sweat or the heating system if we shiver) or to direction (our one token acceptance of cosmic direction being the wearing of sun-glasses because the sun is 'over there'). We have debased what was once the integral nature of life channelled by cosmic orientations - a wholeness - to the ennervated tepidity of skin sensations and retinal discomfort. Our interior body clocks, known as circadian rhythms, continue to operate inside us, but find no contact with the outside world. They therefore become ingrown and frustrated cycles which never interlock with our environment. We are causing ourselves to become meaningless body machines programmed to what looks, in its isolation, to be an arbitrary set of cycles. But by tearing ourselves from our context, like the still-beating heart ripped out of the body of an Aztec victim, we inevitably do violence to our psyches. I would call the new disease, with its side effect of 'alienation of the young', dementia temporalis.

The traditional hospital practice of excluding parents ignored the importance of attachment relationships as regulators of the child’s emotions, behaviour and physiology. The child’s biological status would be vastly different under the circumstances of parental presence or absence. Her neurochemical output, the electrical activity in her brain’s emotional centres, her heart rate, blood pressure and the serum levels of the various hormones related to stress would all vary significantly. Life is possible only within certain well-defined limits, internal or external. We can no more survive, say, high sugar levels in our bloodstream than we can withstand high levels of radiation emanating from a nuclear explosion. The role of self-regulation, whether emotional or physical, may be likened to that of a thermostat ensuring that the temperature in a home remains constant despite the extremes of weather conditions outside. When the environment becomes too cold, the heating system is switched on. If the air becomes overheated, the air conditioner begins to work. In the animal kingdom, self-regulation is illustrated by the capacity of the warm-blooded creature to exist in a broad range of environments. It can survive more extreme variations of hot and cold without either chilling or overheating than can a coldblooded species. The latter is restricted to a much narrower range of habitats because it does not have the capacity to self-regulate the internal environment. Children and infant animals have virtually no capacity for biological self-regulation; their internal biological states—heart rates, hormone levels, nervous system activity — depend completely on their relationships with caregiving grown-ups. Emotions such as love, fear or anger serve the needs of protecting the self while maintaining essential relationships with parents and other caregivers. Psychological stress is whatever threatens the young creature’s perception of a safe relationship with the adults, because any disruption in the relationship will cause turbulence in the internal milieu. Emotional and social relationships remain important biological influences beyond childhood. “Independent self-regulation may not exist even in adulthood,” Dr. Myron Hofer, then of the Departments of Psychiatry and Neuroscience at Albert Einstein College of Medicine in New York, wrote in 1984. “Social interactions may continue to play an important role in the everyday regulation of internal biologic systems throughout life.” Our biological response to environmental challenge is profoundly influenced by the context and by the set of relationships that connect us with other human beings. As one prominent researcher has expressed it most aptly, “Adaptation does not occur wholly within the individual.” Human beings as a species did not evolve as solitary creatures but as social animals whose survival was contingent on powerful emotional connections with family and tribe. Social and emotional connections are an integral part of our neurological and chemical makeup. We all know this from the daily experience of dramatic physiological shifts in our bodies as we interact with others. “You’ve burnt the toast again,” evokes markedly different bodily responses from us, depending on whether it is shouted in anger or said with a smile. When one considers our evolutionary history and the scientific evidence at hand, it is absurd even to imagine that health and disease could ever be understood in isolation from our psychoemotional networks. “The basic premise is that, like other social animals, human physiologic homeostasis and ultimate health status are influenced not only by the physical environment but also by the social environment.” From such a biopsychosocial perspective, individual biology, psychological functioning and interpersonal and social relationships work together, each influencing the other.

With the sound of three short blasts on the ship’s whistle, we backed away from the pier. This ship was unlike most ships and we all noticed a definite difference in her sounds and vibrations. At that time, most American vessels were driven by steam propulsion that relied on superheating the water. The reciprocating steam engines, with their large pistons, were the loudest as they hissed and wheezed, turning a huge crankshaft. Steam turbines were relatively vibration free, but live steam was always visible as it powered the many pumps, winches, etc. Steam is powerful and efficient, but can be dangerous and even deadly. Diesel engines were seldom used on the larger American ships of that era, and were not considered cost or energy efficient. The Empire State was a relatively quiet ship since she only used steam power to drive the turbines, which then spun the generators that made the electricity needed to energize the powerful electric motors, which were directly geared to turn the propeller shafts. All in all, the ship was nearly vibration free, making for a smooth ride. We all had our sea projects to do and although they were not difficult, they were time consuming and thought of as a pain in the azz. The best time to work on these projects was while standing our make-work, lifeboat watches. One of the ship’s lifeboats was always on standby, hanging over the side from its davits. Day and night, we would be ready to launch this boat if somebody fell overboard. Fortunately, this never happened, so with little else to do we had plenty of time to do our projects.

Being constantly active made time fly, and so it didn’t take long before the day of departure came. With the last of everything aboard, we set sail just as many did before us. We were among those that continued the tradition of... “they that go down to the sea in ships” and we were very aware that this tradition rested on our shoulders. On January 4, 1953, with the sound of three short blasts on the ship’s whistle, we backed away from the pier. This ship was unlike most ships and we all noticed a definite difference in her sounds and vibrations.

In this regard, the delicate cell bodies, dendrites, and axons are like the many other fluid-filled tubes within the body. The quality of their function is susceptible to changes in pressure, distortion, viscosity. Their need for constant irrigation is acute: If fresh oxygen is held back from a neuron for merely three to five seconds, it is rendered completely unexcitable.4 And necessary substances must circulate inside the cell as well as around it. If a long dendrite or axon is pinched, closing its length off from the rest of the cell’s fluid, the excitability of the isolated branch quickly decays and eventually the pinched axon or dendrite will atrophy. You can park a truck on top of an electrical wire and it will continue to work nicely. It will work, in fact, until it is completely severed. In contrast there are many intermediate stages of malfunction in a nerve short of this final breakage—or lesion—most of them having to do with the relative effectiveness of the delivery and circulation of nutritional fluids and the adequate flushing of toxins and wastes. These intermediate malfunctions do not normally stop the system; they just make it less efficient. They confuse sensations, cloud thoughts, disturb the precision of our muscular efforts, make us numb in some spots, unaccountably sensitive in others, eliminate responses, force compensations. Insofar as effective bodywork can be of direct benefit to the circulation of bodily fluids, it can help to support the actual metabolic bases of nerve function, and this benefit is above and beyond the question of the value of any actual sensations it may produce.

Your laptop is a note in a symphony currently being played by an orchestra of incalculable size. It’s a very small part of a much greater whole. Most of its capacity resides beyond its hard shell. It maintains its function only because a vast array of other technologies are currently and harmoniously at play. It is fed, for example, by a power grid whose function is invisibly dependent on the stability of a myriad of complex physical, biological, economic and interpersonal systems. The factories that make its parts are still in operation. The operating system that enables its function is based on those parts, and not on others yet to be created. Its video hardware runs the technology expected by the creative people who post their content on the web. Your laptop is in communication with a certain, specified ecosystem of other devices and web servers. And, finally, all this is made possible by an even less visible element: the social contract of trust—the interconnected and fundamentally honest political and economic systems that make the reliable electrical grid a reality. This interdependency of part on whole, invisible in systems that work, becomes starkly evident in systems that don’t. The higher-order, surrounding systems that enable personal computing hardly exist at all in corrupt, third-world countries, so that the power lines, electrical switches, outlets, and all the other entities so hopefully and concretely indicative of such a grid are absent or compromised, and in fact make little contribution to the practical delivery of electricity to people’s homes and factories. This makes perceiving the electronic and other devices that electricity theoretically enables as separate, functional units frustrating, at minimum, and impossible, at worst. This is partly because of technical insufficiency: the systems simply don’t work. But it is also in no small part because of the lack of trust characteristic of systemically corrupt societies. To put it another way: What you perceive as your computer is like a single leaf, on a tree, in a forest—or, even more accurately, like your fingers rubbing briefly across that leaf. A single leaf can be plucked from a branch. It can be perceived, briefly, as a single, self-contained entity—but that perception misleads more than clarifies. In a few weeks, the leaf will crumble and dissolve. It would not have been there at all, without the tree. It cannot continue to exist, in the absence of the tree. This is the position of our laptops in relation to the world. So much of what they are resides outside their boundaries that the screened devices we hold on our laps can only maintain their computer-like façade for a few short years. Almost everything we see and hold is like that, although often not so evidently

The basic order for sorting komono is as follows: 1. CDs, DVDs 2. Skin care products 3. Makeup 4. Accessories 5. Valuables (passports, credit cards, etc.) 6. Electrical equipment and appliances (digital cameras, electric cords, anything that seems vaguely “electric”) 7. Household equipment (stationery and writing materials, sewing kits, etc.) 8. Household supplies (expendables like medicine, detergents, tissues, etc.) 9. Kitchen goods/food supplies (spatulas, pots, blenders, etc.) 10. Other (spare change, figurines, etc.) (If you have many items related to a particular interest or hobby, such as ski equipment or tea ceremony articles, treat these as a single subcategory.)

Sri Yukteswar discovered the mathematical application of a 24,000-year equinoctial cycle to our present age. 4 The cycle is divided into an Ascending Arc and a Descending Arc, each of 12,000 years. Within each Arc fall four Yugas or Ages, called Kali, Dwapara, Treta, and Satya, corresponding to the Greek ideas of Iron, Bronze, Silver, and Golden Ages. My guru determined by various calculations that the last Kali Yuga or Iron Age, of the Ascending Arc, started about a.d. 500. The Iron Age, 1200 years in duration, is a span of materialism; it ended about a.d. 1700. That year ushered in Dwapara Yuga, a 2400-year period of electrical and atomic-energy developments: the age of telegraphy, radio, airplanes, and other space-annihilators. The 3600-year period of Treta Yuga will start in a.d. 4100; the age will be marked by common knowledge of telepathic communications and other time-annihilators. During the 4800 years of Satya Yuga, final age in an Ascending Arc, the intelligence of man will be highly developed; he will work in harmony with the divine plan. A Descending Arc of 12,000 years, starting with a Descending Golden Age of 4800 years, then begins for the world (in a.d. 12,500); man gradually sinks into ignorance. These cycles are the eternal rounds of maya, the contrasts and relativities of the phenomenal universe. 5 Men, one by one, escape from creation’s prison of duality as they awaken to consciousness of their inseverable divine unity with the Creator.

The S curve is not just important as a model in its own right; it’s also the jack-of-all-trades of mathematics. If you zoom in on its midsection, it approximates a straight line. Many phenomena we think of as linear are in fact S curves, because nothing can grow without limit. Because of relativity, and contra Newton, acceleration does not increase linearly with force, but follows an S curve centered at zero. So does electric current as a function of voltage in the resistors found in electronic circuits, or in a light bulb (until the filament melts, which is itself another phase transition). If you zoom out from an S curve, it approximates a step function, with the output suddenly changing from zero to one at the threshold. So depending on the input voltages, the same curve represents the workings of a transistor in both digital computers and analog devices like amplifiers and radio tuners. The early part of an S curve is effectively an exponential, and near the saturation point it approximates exponential decay. When someone talks about exponential growth, ask yourself: How soon will it turn into an S curve? When will the population bomb peter out, Moore’s law lose steam, or the singularity fail to happen? Differentiate an S curve and you get a bell curve: slow, fast, slow becomes low, high, low. Add a succession of staggered upward and downward S curves, and you get something close to a sine wave. In fact, every function can be closely approximated by a sum of S curves: when the function goes up, you add an S curve; when it goes down, you subtract one. Children’s learning is not a steady improvement but an accumulation of S curves. So is technological change. Squint at the New York City skyline and you can see a sum of S curves unfolding across the horizon, each as sharp as a skyscraper’s corner. Most importantly for us, S curves lead to a new solution to the credit-assignment problem. If the universe is a symphony of phase transitions, let’s model it with one. That’s what the brain does: it tunes the system of phase transitions inside to the one outside. So let’s replace the perceptron’s step function with an S curve and see what happens.

These electric and magnetic fields can be elegantly unified into what's known as the electromagnetic field, represented by six numbers at each point in spacetime. As we discussed in Chapter 7, light is simply a wave rippling through the electromagnetic field, so if our physical world is a mathematical structure, then all the light in our Universe (which feels quite physical) corresponds to six numbers at each point in spacetime (which feels quite mathematical). These numbers obey the mathematical relations that we know as Maxwell's equations, shown in Figure 10.4.

There's a caveat here: what I've just described was our understanding of electricity, magnetism and light in classical physics. Quantum mechanics complicates this picture, but without making it any less mathematical, replacing classical electromagnetism with quantum field theory, the bedrock of modern particle physics. In quantum field theory, the wavefunction specifies the degree to which each possible configuration of the electric and magnetic fields is real. This wavefunction is itself a mathematical object, an abstract point in Hilbert space. As we saw in Chapter 7, quantum field theory says that light is made of particles called photons, and, crudely speaking, the numbers constituting the electric and magnetic fields can be thought of as specifying how many photons there are at each time and place. Just as the strength of the electromagnetic field corresponds to the number of photons at each time and place, there are other fields corresponding to all the other elementary particles known. For example, the strengths of the electron field and the quark field relate to the numbers of electrons and quarks at each time and place. In this way, all motions of all particles in all of spacetime correspond, in classical physics, to a bunch of numbers at each point in a four-dimensional mathematical space-a mathematical structure. In quantum field theory, the wavefunction specifies the degree to which each possible configuration of each of these fields is real.

However, the most interesting property of your spacetime tube isn't its bulk shape, but its internal structure, which is remarkably complex. Whereas the particles that constitute the Moon are stuck together in a rather static arrangement, many of your particles are in constant motion relative to one another. Consider, for example, the particles that make up your red blood cells. As your blood circulates through your body to deliver the oxygen you need, each red blood cell traces out its own unique tube shape through spacetime, corresponding to a complex itinerary through your arteries, capillaries and veins with regular returns to your heart and lungs. These spacetime tubes of different red blood cells are intertwined to form a braid pattern (Figure 11.4, middle panel) which is more elaborate than anything you'll ever see in a hair salon: whereas a classic braid consists of three strands with perhaps thirty thousand hairs each, intertwined in a simple repeating pattern, this spacetime braid consists of trillions of strands (one for each red blood cell), each composed of trillions of hairlike elementary-particle trajectories, intertwined in a complex pattern that never repeats. In other words, if you imagine spending a year giving a friend a truly crazy hairdo, braiding his hair by separately intertwining not strands but all the individual hairs, the pattern you'd get would still be very simple in comparison. Yet the complexity of all this pales in comparison to the patterns of information processing in your brain. As we discussed in Chapter 8 and illustrated in Figure 8.7, your roughly hundred billion neurons are constantly generating electric signals ("firing"), which involves shuffling around billions of trillions of atoms, notably sodium, potassium and calcium ions. The trajectories of these atoms form an extremely elaborate braid through spacetime, whose complex intertwining corresponds to storing and processing information in a way that somehow gives rise to our familiar sensation of self-awareness. There's broad consensus in the scientific community that we still don't understand how this works, so it's fair to say that we humans don't yet fully understand what we are. However, in broad brushstrokes, we might say this: You're a pattern in spacetime. A mathematical pattern. Specifically, you're a braid in spacetime-indeed one of the most elaborate braids known.

To do so, we first have to learn to see it for what it is—by cutting through all of the buzzwords, the marketing hype, the pseudoscientific shibboleths and mumbo-jumbo. Then we have to learn to evaluate it: if it is efficient, then by what measure, and who stands to benefit from its efficiency? Efficiency as a euphemism for corporate profitability shouldn’t fool us. Efficiency is a measure that relates productivity (output) to labor and resource inputs; it is meaningless unless we understand all the implications of these inputs and outputs. For a solar panel, does it simply input solar radiation and output electric current? No, its input is all the energy—mainly from fossil fuels—that went into mining, refining, fabricating, finance, design, research, sales, shipping, installation, tech support, maintenance and disposal. Its output is, yes, a modest amount of electricity. It could well turn out that your solar panel is a way to convert a lot of fossil fuel energy into a bit of electricity with the help of sunlight. How efficient is that? Perhaps it would be more efficient to use less electricity—or to not use electricity at all.

During the first century ravens or crows were often taken on board “Viking Knarr’s,” to be released thinking that they would fly in the direction of land. The lookout would observe the direction the birds flew in, so that the navigator could follow their course. Since the crow's nest is high from the vessel’s center of gravity it is subject to violent motion in relatively calm or moderate seas. Any amount of movement of the ship is amplified, causing even seasoned sailors to become sea-sick. Therefore, being sent to the crow's nest was certainly not for everyone. More recently but still prior to the advent of radar, when the visibility from the bridge of the ship was inhibited by fog, heavy seas or limited night vision lookouts were posted on the bow or high on a mast, above the low lying sea fog. By tradition the protected structure fitted to the foremast high above the deck was named the crow’s nest in deference to the earlier Viking traditions. During the 19th century this vantage point was simply made out of a barrel lashed to the highest mast that allowed the lookout to look ahead for land, other ships, flotsam or other obstructions. In later years the crow’s nest was sometimes enclosed and even electrically heated. As a young midshipman I was assigned to the bow as lookout. Peering into the dark of night I suddenly saw a bright light on the horizon. Sighting this light was a thrill and an experience that validated my usefulness! Excited with my find and without a moment’s hesitation I hurried back to where I was within shouting distance from the ships bridge and loudly announced the light as being 2 points on the starboard bow. Proud of my announced discovery, I returned to my station at the bow only to discover that what I had reported was now obviously the tip of a Sickle Moon rising in the east. At the time everyone had a good laugh but I was told that I did the right thing. It took a while but eventually I lived it down and now it makes for a good “Sea Story!”!

The principles of relativity and quantum mechanics are almost incompatible with each other and can coexist only in a limited class of theories. In the nonrelativistic quantum mechanics of the 1920s we could imagine almost any kind of force among electrons and nuclei, but as we shall see, this is not so in a relativistic theory: forces between particles can arise only from the exchange of other particles. Furthermore, all these particles are bundles of the energy, or quanta, of various sorts of fields. A field like an electric or magnetic field is a sort of stress in space, something like the various sorts of stress that are possible within a solid body, but a field is a stress in space itself. There is one type of field for each species of elementary particle; there is an electron field in the standard model, whose quanta are electrons; there is an electromagnetic field (consisting of electric and magnetic fields) , whose quanta are the photons; there is no field for atomic nuclei, or for particles (known as protons and neutrons) of which the nuclei are composed, but there are fields for various types of particles called quarks, out of which the proton and neutron are composed; and there are a few other fields I need not go into right now. The equations of a field theory like the standard model deal not with particles but with fields; the particles appear as manifestations of these fields. The reason that ordinary matter is composed of electrons, protons, and neutrons is simply that all the other massive particles are violently unstable. The standard model qualifies as an explanation because it is not merely what computer hackers call a kludge, an assortment of odds and ends thrown together in whatever way works. Rather, the structure of the standard model is largely fixed once one specifies the menu of fields that it should contain and the general principles (like the principles of relativity and quantum mechanics) that govern their interactions.

Einstein solved the puzzle by playing the same great trick that Newton and Galileo had originally played to establish the relativity of motion. He realized that the distinction between electrical and magnetic effects depends on the motion of the observer. So Maxwell's unification was deeper than even Maxwell had suspected. Not only were the electric and magnetic fields different aspects of a single phenomenon, but different observers would draw the distinction differently; that is, one observer might explain a particular phenomenon in terms of electricity, while another observer, moving relative to the first, would explain the same phenomenon in terms of magnetism. But the two would agree about what was happening. And so Einstein's special theory of relativity was born, as a joining of Galileo's unification of rest and motion with Maxwell's unification of electricity and magnetism.

recent decades, American utility companies have spent relatively little on research and development. One industry report estimates that, in 2009, research-and-development investments made by all US electrical-power utilities amounted to at most $700 million, compared with $6.3 billion by IBM and $9.1 billion by Pfizer. In 2009, however, the Department of Energy issued $3.4 billion in stimulus grants to a hundred smart-grid projects across the United States, including many in areas that are prone to heat waves and hurricanes.

While this signifier can be difficult to pin down with precision, it can clearly be heard in the records of Duane Eddy and many other guitarists of the period. It usually involves a relatively nondistorted electric guitar timbre articulated with a strong attack and a melody played on the lower strings. Reverberation is ubiquitous, and almost equally common were echo, amplifier tremolo, and use of the guitar’s vibrato bar. This overall guitar sound is often called a Fender sound, but that is a bit misleading, since Gretsch guitars were equally specialized for the purpose, and many other brands were also used. What makes the twang guitar interesting in topical terms is that it not only signified the western topic but also was key to a linked set of genres that intersect one another in complex ways: western, spy, and surf. Because these were all signified by overlapping musical features and in turn resemble one another in some of their broader connotations, we could speak of a twang guitar continuum: a range of topics that coalesced only shortly before psychedelia and were cognate with it in a variety of ways. Philip Tagg and Bob Clarida point out that the twang guitar, often in a minor mode with a flat seventh, was a common factor between spaghetti western and Bond/spy scores in the late 1950s and early 1960s. I would add surf guitar to the list, with its sonic experimentation and general relationship to fun, escape, and exoticism: “[The twang guitar] probably owes some of its immediate success as a spy sound to its similarity with various pre-rock ‘Viennese intrigue’ sounds like Anton Karas’s Third Man zither licks (1949). But in the 1962–64 period that produced The Virginian (1962), Dr. No (1963) and Leone’s A Fistful of Dollars (1964), steely Fender guitar was well on its way to becoming an all-purpose excitement/adventure timbre” (Tagg and Clarida 2003, 367).

Apart from all other considerations, the main limitation of analog machines relates to precision. Indeed, the precision of electrical analog machines rarely exceeds 1:10^3, and even mechanical ones achieve at best 1:10^4 to 10^5... On the other hand, to go from 1:10^12 to 1:10^13 in a digital machine means merely adding one place to twelve; this means usually no more than a relative increase in equipment (not everywhere!) of 1/12 = 8.3 percent, and an equal loss in speed (not everywhere!) — none of which is serious.

Analog data are superior for this job because they can be changed back and forth with relative ease whenever the environment within or outside the cell demands it, and they can store an almost unlimited number of possible values, even in response to conditions that have never been encountered before.25 The unlimited number of possible values is why many audiophiles still prefer the rich sounds of analog storage systems. But even though analog devices have their advantages, they have a major disadvantage. In fact, it’s the reason we’ve moved from analog to digital. Unlike digital, analog information degrades over time—falling victim to the conspiring forces of magnetic fields, gravity, cosmic rays, and oxygen. Worse still, information is lost as it’s copied. No one was more acutely disturbed by the problem of information loss than Claude Shannon, an electrical engineer from the Massachusetts Institute of Technology (MIT) in Boston.
