Molecular Quotes

I am done with great things and big things, great institutions and big success, and I am for those tiny, invisible molecular moral forces that work from individual to individual, creeping through the crannies of the world like so many rootlets, or like the capillary oozing of water, yet which if you give them time, will rend the hardest monuments of man's pride.

We humans look rather different from a tree. Without a doubt we perceive the world differently than a tree does. But down deep, at the molecular heart of life, the trees and we are essentially identical.

Down to their innate molecular core, cancer cells are hyperactive, survival-endowed, scrappy, fecund, inventive copies of ourselves.

These days vampires gravitated toward particle accelerators, projects to decode the genome, and molecular biology. Once they had flocked to alchemy, anatomy, and electricity. If it went bang, involved blood, or promised to unlock the secrets of the universe, there was sure to be a vampire around.

They remained imprisoned in the CICU, kept alive in physicality by mechanical devices and medicinal support, inexorably suffering. I revered their resiliency, though I struggled to understand whether they were truly resilient or if this was a descriptive term I used to assure myself that what we were doing was just. Could they merely represent physical beings at this point, molecular derivatives of carbon and water, void of souls that had moved on months prior once the universe had delivered their inevitable fate, simply kept alive by us physicians, who ourselves clutched desperately to the most favored of our prehistoric binary measures of success: life?

I find it easier to believe in God than to believe Hamlet was deduced from the molecular structure of a mutton chop.

Even then, more than a year earlier, there were neurons in her head, not far from her ears, that were being strangled to death, too quietly for her to hear them. Some would argue that things were going so insiduously wrong that the neurons themselves initiated events that would lead to their own destruction. Whether it was molecular murder or cellular suicide, they were unable to warn her of what was happening before they died.

A therapist once said to me, “If you face the choice between feeling guilt and resentment, choose the guilt every time.” It is wisdom I have passed on to many others since. If a refusal saddles you with guilt, while consent leaves resentment in its wake, opt for the guilt. Resentment is soul suicide. Negative thinking allows us to gaze unflinchingly on our own behalf at what does not work. We have seen in study after study that compulsive positive thinkers are more likely to develop disease and less likely to survive. Genuine positive thinking — or, more deeply, positive being — empowers us to know that we have nothing to fear from truth. “Health is not just a matter of thinking happy thoughts,” writes the molecular researcher Candace Pert. “Sometimes the biggest impetus to healing can come from jump-starting the immune system with a burst of long-suppressed anger.” Anger, or the healthy experience of it, is one of the seven A’s of healing. Each of the seven A’s addresses one of the embedded visceral beliefs that predispose to illness and undermine healing.

There are lots of superheroes with different superpowers, and some of them are big and flashy, like super strength and super speed, and molecular restructuring, and force fields. But these abilities are really not so different from the superpower stuff that old Jiko could do, like moving superslow, or reading people's minds, or appearing in doorways, or making people feel okay about themselves by just being there.

The molecular structure of my body has been replaced with nanostructures. They assemble DNA to do extraordinary things. The nano-DNA regenerates cellular structures at the atomic level as my body passes through things. My head hurts trying to process everything. You better not come through any of my walls! Not a chance. I’d be too afraid you might kill me.

I believe that mycelium is the neurological network of nature. Interlacing mosaics of mycelium infuse habitats with information-sharing membranes. These membranes are aware, react to change, and collectively have the long-term health of the host environment in mind. The mycelium stays in constant molecular communication with its environment, devising diverse enzymatic and chemical responses to complex challenges.

Meditation is not just blissing out under a mango tree. It completely changes your brain and therefore changes what you are.

He turned to leave, then hesitated. "One more thing." He walked up to me. "I've also been thinking about your declaration of undying love or whatever." "I didn't - it wasn't -" He clamped his hands on the sides of my gooey face and kissed me. I had to wonder: was it possible to dissolve into chocolate on a molecular level and melt into a puddle on the carpet? Because that's how I felt. I'm pretty sure Valhalla had to resurrect me several times during the course of that kiss. Otherwise, I don't know how I was still in one piece when Alex finally pulled away. He studied me critically, his brown and amber eyes taking me in. He had a chocolate moustache and goatee now, and chocolate down the front of his sweater vest. I'll be honest. A small part of my brain thought, Alex is male right now. I have just been kissed by a dude. How do I feel about that? The rest of my brain answered: I have just been kissed by Alex Fierro. I am absolutely great with that. In fact, I might have done something typically embarrassing and stupid, like making the aforementioned declaration of undying love, but Alex spared me. "Eh." He shrugged. "I'll keep thinking about it. I'll get back to you. In the meantime, definitely take that shower." He left, whistling a tune that might have been a Frank Sinatra song from the elevator, "Fly Me to the Moon".

Molecular evidense suggests that our common ancestor with the chimpanzees lived, in Africa, between 5 and 7 million years ago, say half a million generations ago. This is not long by evolutionary standards.

All approaches at a higher level are suspect until confirmed at the molecular level.

Big industries could keep this look with their molecular level repairing technology. Such a shame!

I’m in love with that girl,” she said out loud in amazement, because she knew that this was a life-changing thing and life-changing things should be said aloud, should have a moment in time, and a place in the air, some molecular structure to make them real. I’m in love with that girl, she heard as it reverberated inside her head. And it was truth, she realised, as things are which you don’t think, but discover have always existed.

Molecular biology has shown that even the simplest of all living systems on the earth today, bacterial cells, are exceedingly complex objects. Although the tiniest bacterial cells are incredibly small, weighing less than 10-12 gms, each is in effect a veritable micro-miniaturized factory containing thousands of exquisitely designed pieces of intricate molecular machinery, made up altogether of one hundred thousand million atoms, far more complicated than any machine built by man and absolutely without parallel in the nonliving world.

As novelist Margaret Atwood wrote to explain women’s absence from quest-for-identity novels, “there’s probably a simple reason for this: send a woman out alone on a rambling nocturnal quest and she’s likely to end up a lot deader a lot sooner than a man would.”3 The irony here is that thanks to molecular archaeology—which includes the study of ancient DNA to trace human movement over time—we now know that men have been the stay-at-homes, and women have been the travelers. The rate of intercontinental migration for women is about eight times that for men.4

Pain? I know pain at the molecular level... It pulls at my atoms... Sings to me in an alphabet of fear... I am the boiling man... come to break the bones of your sins, meat puppet...

Maybe nothing ever happens once and is finished. Maybe happen is never once but like ripples maybe on water after the pebble sinks, the ripples moving on, spreading, the pool attached by a narrow umbilical water-cord to the next pool which the first pool feeds, has fed, did feed, let this second pool contain a different temperature of water, a different molecularity of having seen, felt, remembered, reflect in a different tone the infinite unchanging sky, it doesn’t matter: that pebble’s watery echo whose fall it did not even see moves across its surface too at the original ripple-space, to the old ineradicable rhythm

A curious aspect of the theory of evolution is that everybody thinks he understands it.

It is remarkable that mind enters into our awareness of nature on two separate levels. At the highest level, the level of human consciousness, our minds are somehow directly aware of the complicated flow of electrical and chemical patterns in our brains. At the lowest level, the level of single atoms and electrons, the mind of an observer is again involved in the description of events. Between lies the level of molecular biology, where mechanical models are adequate and mind appears to be irrelevant. But I, as a physicist, cannot help suspecting that there is a logical connection between the two ways in which mind appears in my universe. I cannot help thinking that our awareness of our own brains has something to do with the process which we call "observation" in atomic physics. That is to say, I think our consciousness is not just a passive epiphenomenon carried along by the chemical events in our brains, but is an active agent forcing the molecular complexes to make choices between one quantum state and another. In other words, mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call "chance" when they are made by electrons.

From a limited pallet of molecular components including cellulose, chitosan, and pectin; the very same materials found in trees, crustaceans and apple skins - natural systems embody an extensive array of functional materials that outperform human engineered ones through their resilience, sustainability and adaptability.

As Heinz Pagels has said, The challenge to our civilization which has come from our knowledge of the cosmic energies that fuels the stars, the movement of light and electrons through matter, the intricate molecular order which is the biological basis of life, must be met by the creation of a moral and political order which will accommodate these forces or we shall be destroyed. It will try our deepest resources of reason and compassion.

Instead of an intellectual search, there was suddenly a very deep gut feeling that something was different. It occurred when looking at Earth and seeing this blue-and-white planet floating there, and knowing it was orbiting the Sun, seeing that Sun, seeing it set in the background of the very deep black and velvety cosmos, seeing - rather, knowing for sure - that there was a purposefullness of flow, of energy, of time, of space in the cosmos - that it was beyond man's rational ability to understand, that suddenly there was a nonrational way of understanding that had been beyond my previous experience. There seems to be more to the universe than random, chaotic, purposeless movement of a collection of molecular particles. On the return trip home, gazing through 240,000 miles of space toward the stars and the planet from which I had come, I suddenly experienced the universe as intelligent, loving, harmonious.

They know him at molecular level. He lives in them like chains of matter that determine who they are.

She looked at him. As if she wanted to determine his molecular weight.

Sister love was like food, or air, or memory itself. It was molecular. The very stuff of her.

The result of these cumulative efforts to investigate the cell—to investigate life at the molecular level—is a loud, clear, piercing cry of “design!” The result is so unambiguous and so significant that it must be ranked as one of the greatest achievements in the history of science. The discovery rivals those of Newton and Einstein, Lavoisier and Schrödinger, Pasteur, and Darwin.

One proton of faith, three electrons of humility, a neutron of compassion and a bond of honesty,” Robert said, winking at his daughter. “What’s that?” Cora frowned, confused. Maggie laughed. “That, according to your father, is the molecular structure of love.

Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious principles.

When I started reading the literature of molecular biology, I was stunned by certain descriptions. Admittedly, I was on the lookout for anything unusual, as my investigation had led me to consider that DNA and its cellular machinery truly were an extremely sophisticated technology of cosmic origin. But as I pored over thousands of pages of biological texts, I discovered a world of science fiction that seemed to confirm my hypothesis. Proteins and enzymes were described as 'miniature robots,' ribosomes were 'molecular computers,' cells were 'factories,' DNA itself was a 'text,' a 'program,' a 'language,' or 'data.' One only had to do a literal reading of contemporary biology to reach shattering conclusions; yet most authors display a total lack of astonishment and seem to consider that life is merely 'a normal physiochemical phenomenon.

I am a collection of water, calcium and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label. But is that all? Is there nothing in here but molecules? Some people find this idea somehow demeaning to human dignity. For myself, I find it elevating that our universe permits the evolution of molecular machines as intricate and subtle as we. But the essence of life is not so much the atoms and simple molecules that make us up as the way in which they are put together. Every now and then we read that the chemicals which constitute the human body cost ninety-seven cents or ten dollars or some such figure; it is a little depressing to find our bodies valued so little. However, these estimates are for human beings reduced to our simplest possible components. We are made mostly of water, which costs almost nothing; the carbon is costed in the form of coal; the calcium in our bones as chalk; the nitrogen in our proteins as air (cheap also); the iron in our blood as rusty nails. If we did not know better, we might be tempted to take all the atoms that make us up, mix them together in a big container and stir. We can do this as much as we want. But in the end all we have is a tedious mixture of atoms. How could we have expected anything else?

Hellish goosebumps flash up my back, ripping, like tiny molecular machetes beneath the skin. As a redhead my face has no ability to hide fear.

In fact a favourite problem of Tyndall is—Given the molecular forces in a mutton chop, deduce Hamlet or Faust therefrom. He is confident that the Physics of the Future will solve this easily.

OxyContin is a simple pill. It contains only one drug: oxycodone, a painkiller that Germans synthesized in 1916 from thebaine, an opium derivative. Molecularly, oxycodone is similar to heroin.

Maybe nothing ever happens once and is finished. Maybe happen is never once but like ripples maybe on water after the pebble sinks, the ripples moving on, spreading, the pool attached by a narrow umbilical water-cord to the next pool which the first pool feeds, has fed, did feed, let this second pool contain a different temperature of water, a different molecularity of having seen, felt, remembered, reflect in a different tone the infinite unchanging sky, it doesn’t matter: that pebble’s watery echo whose fall it did not even see moves across its surface too at the original ripple-space, to the old ineradicable rhythm…

Most Muggles lived in a world defined by the limits of what you could do with cars and telephones. Even though Muggle physics explicitly permitted possibilities like molecular nanotechnology or the Penrose process for extracting energy from black holes, most people filed that away in the same section of their brain that stored fairy tales and history books, well away from their personal realities: Long ago and far away, ever so long ago.

The rest of my Thursday can be summarised thus: - Nat tells me to bite her. - I don't. - I am forced to sit next to Toby for the entire two-and-a-half-hour return coach journey. - He tells me that water is not blue because it reflects the sky, but actually because the molecular structure of the water itself reflects the colour blue and therefore our art teacher is wrong and the authorities should be alerted. - I pull my jumper over my head. - I stay under my jumper for the next two hours.

Mushrooms have taught me the interconnectedness of all life-forms and the molecular matrix that we share,” he explains in another one. “I no longer feel that I am in this envelope of a human life called Paul Stamets. I am part of the stream of molecules that are flowing through nature. I am given a voice, given consciousness for a time, but I feel that I am part of this continuum of stardust into which I am born and to which I will return at the end of this life.

Addiction to alcohol is also a neurological phenomenon, the result of a complex set of molecular alterations that take place in the brain when it’s excessively and repeatedly exposed to the drug. The science of addiction is complicated, but the basic idea is fairly straightforward: alcohol appears to wreak havoc on the brain’s natural systems of craving and reward, compromising the functioning of the various neurotransmitters and proteins that create feelings of well-being.

Look at any randomly selected piece of your world. Encoded deep in the biology of every cell in every blade of grass, in every insect’s wing, in every bacterium cell, is the history of the third planet from the Sun in a Solar System making its way lethargically around a galaxy called the Milky Way. Its shape, form, function, colour, smell, taste, molecular structure, arrangement of atoms, sequence of bases, and possibilities for the future are all absolutely unique. There is nowhere else in the observable Universe where you will see precisely that little clump of emergent, living complexity. It is wonderful.

Time is an illusion, say the scientists. It is molecular, it is bendable or liquid, it is soldered metal; or it is droplets of memory. I imagine it looks like mercury, silver and elusive...Burn all the clocks. I am free.

I think that the formation of [DNA's] structure by Watson and Crick may turn out to be the greatest developments in the field of molecular genetics in recent years.

I am kissing her for a reason that transcends want and need, that feels elemental to our existence, a molecular component on which our universe will be built.

What is truly revolutionary about molecular biology in the post-Watson-Crick era is that it has become digital...the machine code of the genes is uncannily computer-like.' -Richard Dawkins

The administration of a great organized molar security has as its correlate a whole micro-management of petty fears, a permanent molecular insecurity, to the point that the motto of domestic policymakers might be: a macropolitics of society by and for the micropolitics of insecurity

Shamanism resembles an academic discipline (such as anthropology or molecular biology); with its practitioners, fundamental researchers, specialists, and schools of thought it is a way of apprehending the world that evolves constantly. One thing is certain: Both indigenous and mestizo shamans consider people like the Shipibo-Conibo, the Tukano, the Kamsá, and the Huitoto as the equivalents to universities such as Oxford, Cambridge, Harvard, and the Sorbonne; they are the highest reference in matters of knowledge. In this sense, ayahuasca-based shamanism is an essentially indigenous phenomenon. It belongs to the indigenous people of Western Amizonia, who hold the keys to a way of knowing that they have practiced without interruption for at least five thousand years. In comparison, the universities of the Western world are less than nine hundred years old.

In fact a favourite problem of [John Tyndall] is—Given the molecular forces in a mutton chop, deduce Hamlet or Faust therefrom. He is confident that the Physics of the Future will solve this easily.

To the physicist – but only to him – I could hope to make my view clearer by saying: The living organism seems to be a macroscopic system which in part of its behaviour approaches to that purely mechanical (as contrasted with thermodynamical) conduct to which all systems tend, as the temperature approaches the absolute zero and the molecular disorder is removed.

It is my belief that the basic knowledge that we're providing to the world will have a profound impact on the human condition and the treatments for disease and our view of our place on the biological continuum.

In the infinite permutations of an ice crystal, everything repeats itself, but, really, from another point of view, nothing repeats itself. The arms go out, forming dendrites, sectored plates, the same angle every time, but the final product – because of wind, because of molecular vibration, because of rate of growth and temperature – is never the same.

To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a thousand million times until it is twenty kilometers in diameter and resembles a giant airship large enough to cover a great city like London or New York. What we would then see would be an object of unparalleled complexity and adaptive design. On the surface of the cell we would see millions of openings, like the port holes of a vast space ship, opening and closing to allow a continual stream of materials to flow in and out. If we were to enter one of these openings we would find ourselves in a world of supreme technology and bewildering complexity.

Shall we walk through the woods; dance through the meadows; and celebrate the miracle of this garden world?

If it's true there's a beginning to the universe, as modern cosmologists now agree, then this implies a cause that transcends the universe. If the laws of physics are fine-tuned to permit life, as contemporary physicists are discovering, then perhaps there's a designer who fine-tuned them. If there's information in the cell, as molecular biology shows, then this suggests intelligent design. To get life going in the first place would have required biological information; the implications point beyond the material realm to a prior intelligent cause. -Stephen C Meyer, PHD

Please remember always... In a contest between the Truth and lies; Truth will always win. Truth is Eternal; and connected to Forever. Lies are merely temporal; illusionary and ephemeral.

I am, a spectator, so to speak of the molecular whirlwind which men call individual life; I am conscious of an incessant metamorphosis; an irresistible movement of existence, which is going on within me – and this phenomenology of myself serves as a window opened upon the mystery of the world.

The mystical perception (which is only “mystical” if reality is limited to what can be measured by the intellect and senses) is remarkably consistent in all ages and all places. All phenomena are processes, connections, all is in flux…have the mind screens knocked away to see there is no real edge to anything, that in the endless interpenetration of the universe, a molecular flow, a cosmic energy shimmers in all stone and steel as well as flesh…

When animals make a stupid mistake, you laugh at them. A cat misjudges a leap. A dog looks overly quizzical about a simple object. These are funny things. But when a person doesn’t understand something, if they miscalculate and hit the brakes too late, blame is assigned. They are stupid. They are wrong. Teachers and cops are there to sort it out, with a trail of paperwork to illustrate the stupidity. The faults. The evidence and incidents of these things. We have entire systems in place to help decide who is what. Sometimes the systems don’t work. Families spend their weekend afternoons at animal shelters, even when they’re not looking for a pet. They come to see the unwanted and unloved. The cats and dogs who don’t understand why they are these things. They are petted and combed, walked and fed, cooed over and kissed. Then they go back in their cages and sometimes tears are shed. Fuzzy faces peering through bars can be unbearable for many. Change the face to a human one and the reaction changes. The reason why is because people should know better. But our logic is skewed in this respect. A dog that bites is a dead dog. First day at the shelter and I already saw one put to sleep, which in itself is a misleading phrase. Sleep implies that you have the option of waking up. Once their bodies pass unconsciousness to something deeper where systems start to fail, they revolt a little bit, put up a fight on a molecular level. They kick. They cry. They don’t want to go. And this happens because their jaws closed over a human hand, ever so briefly. Maybe even just the once. But people, they get chances. They get the benefit of the doubt. Even though they have the higher logic functioning and they knew when they did it THEY KNEW it was a bad thing.

I am a collection of water, calcium and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label. But is that all? Is there nothing in here but molecules? Some people find this idea somehow demeaning to human dignity. For myself, I find it elevating that our universe permits the evolution of molecular machines as intricate and subtle as we.

I decided that life rationally considered seemed pointless and futile, but it is still interesting in a variety of ways, including the study of science. So why not carry on, following the path of scientific hedonism? Besides, I did not have the courage for the more rational procedure of suicide.

A year later, less than 1 percent was gone. “And that’s under the best controlled laboratory conditions. That’s not what you will find in real life,” says Tony Andrady. “Plastics haven’t been around long enough for microbes to develop the enzymes to handle it, so they can only biodegrade the very-low-molecular-weight part of the plastic”—meaning, the smallest, already-broken polymer chains. Although truly biodegradable plastics derived from natural plant sugars have appeared, as well as biodegradable polyester made from bacteria, the chances of them replacing the petroleum-based originals aren’t great.

Every disease that’s with us is caused by DNA. And every disease can be fixed by DNA.

I think knowledge is a blessing, not a curse. This is especially true in the case of genetic knowledge. To understand the molecular nature of cancer for the first time, to diagnose and prevent Alzheimer’s disease, to discover the secrets of human history, to reconstruct the organisms that populated the pre-Cambrian seas – these seem to me to be immense blessings.

Whatever the nature of organizing relations may be,' J. Needham wrote in 1932, 'they form the central problem of biology, and biology will be fruitful in the future only if this is recognized. The hierarchy of relations, from the molecular structure of carbon compounds to the equilibrium of species and ecological wholes, will perhaps be the leading idea of the future.

If a fish is born in your aquarium and you call him John, write out a birth certificate, tell him about his family history, and two minutes later he gets eaten by another fish — that’s tragic. But it’s only tragic because you projected a separate self where there was none. You got hold of a fraction of a dynamic process, a molecular dance, and made a separate entity out of it.

Stress can be bad for you. We no longer die of smallpox or the plague and instead die of stress-related diseases of lifestyle, like heart disease or diabetes, where damage slowly accumulates over time. It is understood how stress can cause or worsen disease or make you more vulnerable to other risk factors. Much of this is even understood on the molecular level. Stress can even cause your immune system to abnormally target hair follicles, causing your hair to turn gray.

Suddenly I realized that a cell's life is controlled by the physical and energetic environment and not by its genes. Genes are simply molecular blueprints used in the construction of cells, tissues, and organs. The environment serves as a "contractor" who reads and engages those genetic blueprints and is ultimately responsible for the character of a cell's life. It is a single cell's "awareness" of the environment, not its genes, that sets into motion the mechanisms of life.

The living cell is the most complex system of its size known to mankind. Its host of specialized molecules, many found nowhere else but within living material, are themselves already enormously complex. They execute a dance of exquisite fidelity, orchestrated with breathtaking precision. Vastly more elaborate than the most complicated ballet, the dance of life encompasses countless molecular performers in synergetic coordination. Yet this is a dance with no sign of a choreographer. No intelligent supervisor, no mystic force, no conscious controlling agency swings the molecules into place at the right time, chooses the appropriate players, closes the links, uncouples the partners, moves them on. The dance of life is spontaneous, self-sustaining, and self-creating.

[W]ithout changing the most molecular relationships in society — notably, those between men and women, adults and children, whites and other ethnic groups, heterosexuals and gays (the list, in fact, is considerable) — society will be riddled by domination even in a socialistic ‘classless’ and ‘non-exploitative’ form. It would be infused by hierarchy even as it celebrated the dubious virtues of ‘people’s democracies,’ ’socialism’ and the ‘public ownership’ of ‘natural resources,’ And as long as hierarchy persists, as long as domination organises humanity around a system of elites, the project of dominating nature will continue to exist and inevitably lead our planet to ecological extinction

Molecular genetic evidence (see Chapter 10 for the nature of this kind of evidence) shows that the closest living cousins of whales are hippos, then pigs, then ruminants. Even more surprisingly, the molecular evidence shows that hippos are more closely related to whales than they are to the cloven-hoofed animals

When does a physical system – any kind of association of atoms – display ‘dynamical law’ (in Planck’s meaning) or ‘clock-work features’? Quantum theory has a very short answer to this question, viz. at the absolute zero of temperature. As zero temperature is approached the molecular disorder ceases to have any bearing on physical events.

Q. How does the ego handle truth? A. The larger the ego; the less truth can be handled. Arriving at total Truth is the end of ego altogether.

All will be as miraculous as you allow.

Remember that your perception of the world is a reflection of your state of consciousness. You are not separate from it, and there is no objective world out there. Every moment, your consciousness creates the world that you inhabit. One of the greatest insights that has come out of modern physics is that of the unity between the observer and the observed: the person conducting the experiment — the observing consciousness — cannot be separated from the observed phenomena, and a different way of looking causes the observed phenomena to behave differently. If you believe, on a deep level, in separation and the struggle for survival, then you see that belief reflected all around you and your perceptions are governed by fear. You inhabit a world of death and of bodies fighting, killing, and devouring each other. Nothing is what it seems to be. The world that you create and see through the egoic mind may seem a very imperfect place, even a vale of tears. But whatever you perceive is only a kind of symbol, like an image in a dream. It is how your consciousness interprets and interacts with the molecular energy dance of the universe. This energy is the raw material of so-called physical reality. You see it in terms of bodies and birth and death, or as a struggle for survival. An infinite number of completely different interpretations, completely different worlds, is possible and, in fact, exists — all depending on the perceiving consciousness. Every being is a focal point of consciousness, and every such focal point creates its own world, although all those worlds are interconnected. There is a human world, an ant world, a dolphin world, and so on. There are countless beings whose consciousness frequency is so different from yours that you are probably unaware of their existence, as they are of yours. Highly conscious beings who are aware of their connectedness with the Source and with each other would inhabit a world that to you would appear as a heavenly realm — and yet all worlds are ultimately one.

A tree inhales and stills air’s fibrillating breath, holding it in wood, like a kami. Each year’s growth rings jackets the previous, capturing in layered derma precise molecular signatures of the atmosphere timbered memories. Wood emerges from relationship with air, catalyzed by the flash of electrons through membranes. Atmosphere and plant make each other; plant as temporary crystallization of carbon, air as product of 400 million years of forest breath. Neither tree nor air has a narrative, a telos of its own, for neither is its own.

Nonetheless, the appeal of Copenhagen makes some sense, seen in this light. Quantum physics drove much of the technological and scientific progress of the past ninety years: nuclear power, modern computers, the Internet. Quantum-driven medical imaging changed the face of health care; quantum imaging techniques at smaller scales have revolutionized biology and kicked off the entirely new field of molecular genetics. The list goes on. Make some kind of personal peace with Copenhagen, and contribute to this amazing revolution in science . . . or take quantum physics seriously, and come face-to-face with a problem that even Einstein couldn't solve. Shutting up never looked so good.

Movement is big medicine; it’s the signal to every cell in our bodies that no matter what kind of damage we’ve suffered, we’re ready to rebuild and move away from death and back toward life. Rest too long after an injury and your system powers down, preparing you for a peaceful exit. Fight your way back to your feet, however, and you trigger that magical ON switch that speeds healing hormones to everything you need to get stronger: your bones, brain, organs, ligaments, immune system, even the digestive bacteria in your belly, all get a molecular upgrade from exercise. For

The bombs disrupted molecular structures. The cocktails included the distribution of nanotechnology to help to speed up the recovery of the earth - nanotechnology that promotes the self-assembly of molecules. The nanotechnology, speed up by DNA, which is an informational material but also excellent at the self-assembly of cells, made our fusing stronger. And the nanotechnology that hit the humans trapped in rubble or scorched land helped them to regenerate.

Thermodynamics is one of those words best avoided in a book with any pretence to be popular, but it is more engaging if seen for what it is: the science of 'desire'. The existence of atoms and molecules is dominated by 'attractions', 'repulsions', 'wants' and 'discharges', to the point that it becomes virtually impossible to write about chemistry without giving in to some sort of randy anthromorphism. Molecules 'want' to lose or gain electrons; attract opposite charges; repulse similar charges; or cohabit with molecules of similar character. A chemical reaction happens spontaneously if all the molecular partners desire to participate; or they can be pressed to react unwillingly through greater force. And of course some molecules really want to react but find it hard to overcome their innate shyness. A little gentle flirtation might prompt a massive release of lust, a discharge of pure energy. But perhaps I should stop there.

What advise to you offer to those who are awakened? If you have awakened I offer no advise. For as the 'awakened' you see with Universal Mind and you feel with Universal Love. You exist entirely here within the Infinite Now. Namaste ~ L

Ebola Zaire attacks every organ and tissue in the human body except skeletal muscle and bone. It is a perfect parasite because it transforms virtually every part of the body into a digested slime of virus particles. The seven mysterious proteins that, assembled together, make up the Ebola-virus particle, work as a relentless machine, a molecular shark, and they consume the body as the virus makes copies of itself. Small blood clots begin to appear in the bloodstream, and the blood thickens and slows, and the clots begin to stick to the walls of blood vessels. This is known as pavementing, because the clots fit together in a mosaic. The mosaic thickens and throws more clots, and the clots drift through the bloodstream into the small capillaries, where they get stuck. This shuts off the blood supply to various parts of the body, causing dead spots to appear in the brain, liver, kidneys, lungs, intestines, testicles, breast tissue (of men as well as women), and all through the skin.

I’m not sure, though, what “for later” means anymore. Something changed in the world. Not too long ago, it changed, and we know it. We don’t know how to explain it yet, but I think we all can feel it, somewhere deep in our gut or in our brain circuits. We feel time differently. No one has quite been able to capture what is happening or say why. Perhaps it’s just that we sense an absence of future, because the present has become too overwhelming, so the future has become unimaginable. And without future, time feels like only an accumulation. An accumulation of months, days, natural disasters, television series, terrorist attacks, divorces, mass migrations, birthdays, photographs, sunrises. We haven’t understood the exact way we are now experiencing time. And maybe the boy’s frustration at not knowing what to take a picture of, or how to frame and focus the things he sees as we all sit inside the car, driving across this strange, beautiful, dark country, is simply a sign of how our ways of documenting the world have fallen short. Perhaps if we found a new way to document it, we might begin to understand this new way we experience space and time. Novels and movies don’t quite capture it; journalism doesn’t; photography, dance, painting, and theater don’t; molecular biology and quantum physics certainly don’t either. We haven’t understood how space and time exist now, how we really experience them. And until we find a way to document them, we will not understand them.

The commercialization of molecular biology is the most stunning ethical event in the history of science, and it has happened with astonishing speed. For four hundred years since Galileo, science has always proceeded as a free and open inquiry into the workings of nature. Scientists have always ignored national boundaries, holding themselves above the transitory concerns of politics and even wars. Scientists have always rebelled against secrecy in research, and have even frowned on the idea of patenting their discoveries, seeing themselves as working to the benefit of all mankind. And for many generations, the discoveries of scientists did indeed have a peculiarly selfless quality... Suddenly it seemed as if everyone wanted to become rich. New companies were announced almost weekly, and scientists flocked to exploit genetic research... It is necessary to emphasize how significant this shift in attitude actually was. In the past, pure scientists took a snobbish view of business. They saw the pursuit of money as intellectually uninteresting, suited only to shopkeepers. And to do research for industry, even at the prestigious Bell or IBM labs, was only for those who couldn't get a university appointment. Thus the attitude of pure scientists was fundamentally critical toward the work of applied scientists, and to industry in general. Their long-standing antagonism kept university scientists free of contaminating industry ties, and whenever debate arose about technological matters, disinterested scientists were available to discuss the issues at the highest levels. But that is no longer true. There are very few molecular biologists and very few research institutions without commercial affiliations. The old days are gone. Genetic research continues, at a more furious pace than ever. But it is done in secret, and in haste, and for profit.

I was ready when Quentin approached me after school the following day. “Genie,” he said. “Please. Let me expl—moomph!” “Stay away,” I said, mashing the bulb of garlic into his face as hard as I could. I didn’t have any crosses or holy water at home. I had to work with what was available. Quentin slowly picked the cloves out of my hand before popping them into his mouth. “That’s white vampires,” he said, chewing and swallowing the raw garlic like a bite of fruit. “If I was a jiangshi you should have brought a mirror.” I wrinkled my nose. “You’re going to stink now.” “What, like a Chinese?” He pursed his lips and blew a kiss at me. Instead of being pungent, his breath was sweet with plum blossoms and coconut. Like his body magically refused to be anything but intensely appealing to me, even on a molecular level. I tried to swat away his scent before it made me drunk.

Classically, cosmetics companies will take highly theoretical, textbookish information about the way that cells work—the components at a molecular level or the behavior of cells in a glass dish—and then pretend it’s the same as the ultimate issue of whether something makes you look nice. “This molecular component,” they say, with a flourish, “is crucial for collagen formation.” And that will be perfectly true (along with many other amino acids which are used by your body to assemble protein in joints, skin, and everywhere else), but there is no reason to believe that anyone is deficient in it or that smearing it on your face will make any difference to your appearance. In general, you don’t absorb things very well through your skin, because its purpose is to be relatively impermeable. When you sit in a bath of baked beans for charity, you do not get fat, nor do you start farting.

they say that everything in the world is an illusion, that it’s not real. but how’s it an illusion? who’d say those real, material things right there in front of you are fake, right? the form that material things exist in is one way, while the form they manifest in, it turns out, is different. and our eyes have an ability: they can fix the material things in our material dimension so that they appear to be in the state we now see. but actually, that’s not their state. that’s not even their state in our dimension. for example, what does a human being look like under a microscope? his whole body is loose and made up of little molecules, just like grains of sand, and they’re granular and in motion, electrons are orbiting nuclei, the whole body is wriggling and in motion, and the surface of the body isn’t smooth, it’s irregular. the same goes for every material thing in the universe, be it steel, iron, stone, or whatever, all the molecular elements inside them are in motion. you really can’t see the overall form of it, and the truth is, none of those things are static. this table is wriggling too, but your eyes can’t see the reality of it. so this pair of eyes can give you a false image.

The truth is that anxiety is at once a function of biology and philosophy, body and mind, instinct and reason, personality and culture. Even as anxiety is experienced at a spiritual and psychological level, it is scientifically measurable at the molecular level and the physiological level. It is produced by nature and it is produced by nurture. It’s a psychological phenomenon and a sociological phenomenon. In computer terms, it’s both a hardware problem (I’m wired badly) and a software problem (I run faulty logic programs that make me think anxious thoughts). The origins of a temperament are many faceted; emotional dispositions that may seem to have a simple, single source—a bad gene, say, or a childhood trauma—may not.

V drifts into talking about generations. How grandparents and grandchildren so often get along very well. Remove one generation—twenty-five years at least—and the anger in both directions dissipates. All the failed expectations and betrayals become cleansed by an intervention of time. Resentment and bitter need for retribution fall away. Love becomes the operative emotion. On the old side, you’re left with wrinkled age and whatever fractured, end-of-the-line knowledge might have accrued. Wisdom as exhaustion. And on the other side—which V still remembers with molecular vividness—youth and yearning and urgency for something not yet fully defined. Undiluted hope and desire. But by fusing the best of both sides, a kind of intertwining consciousness arises—grandmother and granddaughter wisdom emerging from shared hope, relieved of emotions tainted by control and guilt and anger. —I’ll assume you’re right, James says. But I wouldn’t know much about long family relationships. When I was

Ebola Zaire attacks every organ and tissue in the human body except skeletal muscle and bone. It is a perfect parasite because it transforms virtually every part of the body into a digested slime of virus particles. The seven mysterious proteins that, assembled together, make up the Ebola-virus particle, work as a relentless machine, a molecular shark, and they consume the body as the virus makes copies of itself. Small blood clots begin to appear in the bloodstream, and the blood thickens and slows, and the clots begin to stick to the walls of blood vessels. This is known as pavementing, because the clots fit together in a mosaic. The mosaic thickens and throws more clots, and the clots drift through the bloodstream into the small capillaries, where

It is a strange, nonintuitive fact of existence that photons of light have no color, sound waves no sound, olfactory molecules no odors. As James Le Fanu has put it, “While we have the overwhelming impression that the greenness of the trees and the blueness of the sky are streaming through our eyes as through an open window, yet the particles of light impacting on the retina are colourless, just as the waves of sound impacting on the eardrum are silent and scent molecules have no smell. They are all invisible, weightless, subatomic particles of matter travelling through space.” All the richness of life is created inside your head. What you see is not what is but what your brain tells you it is, and that’s not the same thing at all. Consider a bar of soap. Has it ever struck you that soap lather is always white no matter what color the soap is? That isn’t because the soap somehow changes color when it is moistened and rubbed. Molecularly, it’s exactly as it was before. It’s just that the foam reflects light in a different way. You get the same effect with crashing waves on a beach—greeny-blue water, white foam—and lots of other phenomena. That is because color isn’t a fixed reality but a perception.

When the child asks: "Why have the leaves turned red?" or "Why does it snow?" we launch into explanations which have no obvious connection with the question. Leaves are red because it is cold, we say. What has cold to do with colour? How is the child to know that we are talking of abstract connections between atmospheric conditions and leaf chemistry? And why should he care? The child has asked 'why,' not 'how,' and certainly not 'how much.' And why should he care the molecular structure of water is believed to be such that at low temperatures it forms rigid bonds which make it appear as ice or snow? None of these abstractions says anything about what the child experiences: the redness of leaves and the cool, tickling envelopment by snow. The living response would be quite different. 'Why are the leaves red Dad?" "Because it is so beautiful, child. Don't you see how beautiful it is, all these autumn colours?" There is no truer answer. That is how the leaves are red. An answer which does not invoke questions, which does not lead the child into an endless series of questions, to which each answer is a threshold. The child will hear later on that a chemical reaction occurs in those leaves. It is bad enough, then; let us not make the world uninhabitable for the child too soon.

Although Galileo was a devout Catholic, it was his conflict with the Vatican, sadly mismanaged on both sides, that lay at the basis of the running battle between science and religion, a tragic and confusing schism which persists unresolved. More than ever today, religion finds its revelatory truths threatened by scientific theory, and retreats into a defensive corner, while scientists go into the attack insisting that rational argument is the only valid criterion for an understanding of the workings of the universe. Maybe both sides have misunderstood the nature of their respective roles. Scientists are equipped to answer the mechanical question of how the universe and everything in it, including life, came about. But since their modes of thought are dictated by purely rational, materialistic criteria, physicists cannot claim to answer the questions of why the universe exists, and why we human beings are here to observe it, any more than molecular biologists can satisfactorily explain why – if our actions are determined by the workings of a selfish genetic coding – we occasionally listen to the voice of conscience and behave with altruism, compassion and generosity. Even these human qualities have come under attack from evolutionary psychologists who have ascribed altruism to a crude genetic theory by which familial cooperation is said to favour the survival of the species. Likewise the spiritual sophistication of musical, artistic and poetic activity is regarded as just a highly advanced function of primitive origins.

A major push is under way to figure out the molecular basis of those "critical" or "sensitive" periods, to figure out how the brain changes as certain learning abilities come and go. In some, if not all, of those mammals that have the alternating stripes in the visual cortex known as ocular dominance columns, those columns can be adjusted early in development, but not in adulthood. A juvenile monkey that has one eye covered for an extended period of time can gradually readjust its brain wiring to favor the open eye; an adult monkey cannot adjust its wiring. At the end of a critical period, a set of sticky sugar-protein hybrids known as proteoglycans condenses into a tight net around the dendrites and cell bodies of some of the relevant neurons, and in so doing those proteoglycans appear to impede axons that would otherwise be wriggling around as part of the process of readjusting the ocular dominance columns; no wriggling, no learning. In a 2002 study with rats, Italian neuroscientist Tommaso Pizzorusso and his colleagues dissolved the excess proteoglycans with an antiproteoglycan enzyme known as "chABC," and in so doing managed to reopen the critical period. After the chABC treatment, even adult rats could recalibrate their ocular dominance columns. ChABC probably won't help us learn second languages anytime soon, but its antiproteoglycan function may have important medical implications in the not-too-distant future. Another 2002 study, also with rats, showed that chABC can also promote functional recovery after spinal cord injury.

Only the middle distance and what may be called the remoter foreground are strictly human. When we look very near or very far, man either vanishes altogether or loses his primacy. The astronomer looks even further afield than the Sung painter and sees even less of human life. At the other end of the scale the physicist, the chemist, the physiologist pursue the close-up – the cellular close-up, the molecular, the atomic and subatomic. Of that which, at twenty feet, even at arm’s length, looked and sounded like a human being no trace remains. Something analogous happens to the myopic artist and the happy lover. In the nuptial embrace personality is melted down; the individual (it is the recurrent theme of Lawrence’s poems and novels) ceases to be himself and becomes a part of the vast impersonal universe. And so it is with the artist who chooses to use his eyes at the near point. In his work humanity loses its importance, even disappears completely. Instead of men and women playing their fantastic tricks before high heaven, we are asked to consider the lilies, to meditate on the unearthly beauty of ‘mere things,’ when isolated from their utilitarian context and rendered as they are, in and for themselves. Alternatively (or, at an earlier stage of artistic development, exclusively), the nonhuman world of the near-point is rendered in patterns. These patterns are abstracted for the most part from leaves and flowers – the rose, the lotus, the acanthus, palm, papyrus – and are elaborated, with recurrences and variations, into something transportingly reminisce

Mates are … an intense thing for the Fae.” She swallowed audibly. “It’s a lifetime commitment. Something sworn between bodies and hearts and souls. It’s a binding between beings. You say I’m your mate in front of any Fae, and it’ll mean something big to them.” “And we don’t mean something big like that?” he asked carefully, hardly daring to breathe. She held his heart in her hands. Had held it since day one. “You mean everything to me,” she breathed, and he exhaled deeply. “But if we tell Ruhn that we’re mates, we’re as good as married. To the Fae, we’re bound on a biological, molecular level. There’s no undoing it.” “Is it a biological thing?” “It can be. Some Fae claim they know their mates from the moment they meet them. That there’s some kind of invisible link between them. A scent or soul-bond.” “Is it ever between species?” “I don’t know,” she admitted, and ran her fingers over his chest in dizzying, taunting circles. “But if you’re not my mate, Athalar, no one is.” “A winning declaration of love.” She scanned his face, earnest and open in a way she so rarely was with others. “I want you to understand what you’re telling people, telling the Fae, if you say I’m your mate.” “Angels have mates. Not as … soul-magicky as the Fae, but we call life partners mates in lieu of husbands or wives.” Shahar had never called him such a thing. They’d rarely even used the term lover. “The Fae won’t differentiate. They’ll use their intense-ass definition.” He studied her contemplative face. “I feel like it fits. Like we’re already bound on that biological level.” “Me too. And who knows? Maybe we’re already mates.

Competition is the spice of sports; but if you make spice the whole meal you'll be sick. The simplest single-celled organism oscillates to a number of different frequencies, at the atomic, molecular, sub-cellular, and cellular levels. Microscopic movies of these organisms are striking for the ceaseless, rhythmic pulsation that is revealed. In an organism as complex as a human being, the frequencies of oscillation and the interactions between those frequencies are multitudinous. -George Leonard Learning any new skill involves relatively brief spurts of progress, each of which is followed by a slight decline to a plateau somewhat higher in most cases than that which preceded it…the upward spurts vary; the plateaus have their own dips and rises along the way…To take the master’s journey, you have to practice diligently, striving to hone your skills, to attain new levels of competence. But while doing so–and this is the inexorable–fact of the journey–you also have to be willing to spend most of your time on a plateau, to keep practicing even when you seem to be getting nowhere. (Mastery, p. 14-15). Backsliding is a universal experience. Every one of us resists significant change, no matter whether it’s for the worse or for the better. Our body, brain and behavior have a built-in tendency to stay the same within rather narrow limits, and to snap back when changed…Be aware of the way homeostasis works…Expect resistance and backlash. Realize that when the alarm bells start ringing, it doesn’t necessarily mean you’re sick or crazy or lazy or that you’ve made a bad decision in embarking on the journey of mastery. In fact, you might take these signals as an indication that your life is definitely changing–just what you’ve wanted….Be willing to negotiate with your resistance to change. Our preoccupation with goals, results, and the quick fix has separated us from our own experiences…there are all of those chores that most of us can’t avoid: cleaning, straightening, raking leaves, shopping for groceries, driving the children to various activities, preparing food, washing dishes, washing the car, commuting, performing the routine, repetitive aspects of our jobs….Take driving, for instance. Say you need to drive ten miles to visit a friend. You might consider the trip itself as in-between-time, something to get over with. Or you could take it as an opportunity for the practice of mastery. In that case, you would approach your car in a state of full awareness…Take a moment to walk around the car and check its external condition, especially that of the tires…Open the door and get in the driver’s seat, performing the next series of actions as a ritual: fastening the seatbelt, adjusting the seat and the rearview mirror…As you begin moving, make a silent affirmation that you’ll take responsibility for the space all around your vehicle at all times…We tend to downgrade driving as a skill simply because it’s so common. Actually maneuvering a car through varying conditions of weather, traffic, and road surface calls for an extremely high level of perception, concentration, coordination, and judgement…Driving can be high art…Ultimately, nothing in this life is “commonplace,” nothing is “in between.” The threads that join your every act, your every thought, are infinite. All paths of mastery eventually merge. [Each person has a] vantage point that offers a truth of its own. We are the architects of creation and all things are connected through us. The Universe is continually at its work of restructuring itself at a higher, more complex, more elegant level . . . The intention of the universe is evolution. We exist as a locus of waves that spreads its influence to the ends of space and time. The whole of a thing is contained in each of its parts. We are completely, firmly, absolutely connected with all of existence. We are indeed in relationship to all that is.

Entirely my own opinion,” said Ivanov. “I am glad that we have reached the heart of the matter soon. In other words: you are convinced that “we” – that is to say, the Party, the State and the masses behind it – no longer represent the interests of the Revolution.” “I should leave the masses out of it,” said Rubashov. […] “Leave the masses out of it, “ he repeated. “You understand nothing about them. Nor, probably, do I any more. Once, when the great “we” still existed, we understood them as no one had ever understood them before. We had penetrated into their depths, we worked in the amorphous raw material of history itself…” […] “At that time,” Rubashov went on, “we were called the Party of the Plebs. What did the others know of history? Passing ripples, little eddies and breaking waves. They wondered at the changing forms of the surface and could not explain them. But we had descended into the depths, into the formless, anonymous masses, which at all times constituted the substance of history; and we were the first to discover her laws of motion. We had discovered the laws of her inertia, of the slow changing of her molecular structure, and of her sudden eruptions. That was the greatness of our doctrine. The Jacobins were moralists; we were empirics. We dug in the primeval mud of history and there we found her laws. We knew more than ever men have known about mankind; that is why our revolution succeeded. And now you have buried it all again….” […] “Well,” said Rubashov, “one more makes no difference. Everything is buried: the men, their wisdom and their hopes. You killed the “We”; you destroyed it. Do you really maintain that the masses are still behind you? Other usurpers in Europe pretend the same thing with as much right as you….” […] “Forgive my pompousness,” he went on, “but do you really believe the people are still behind you? It bears you, dumb and resigned, as it bears others in other countries, but there is no response in their depths. The masses have become deaf and dumb again, the great silent x of history, indifferent as the sea carrying the ships. Every passing light is reflected on its surface, but underneath is darkness and silence. A long time ago we stirred up the depths, but that is over. In other words” – he paused and put on his pince-nez – “in those days we made history; now you make politics. That’s the whole difference.” […] "A mathematician once said that algebra was the science for lazy people - one does not work out x, but operates with it as if one knew it. In our case, x stands for the anonymous masses, the people. Politics mean operating with this x without worrying about its actual nature. Making history is to recognize x for what it stands for in the equation." "Pretty," said Ivanov. "But unfortunately rather abstract. To return to more tangible things: you mean, therefore, that "We" - namely, Party and State - no longer represent the interests of the Revolution, of the masses or, if you like, the progress of humanity." "This time you have grasped it," said Rubashov smiling. Ivanov did not answer his smile.

I am, reluctantly, a self-confessed carbon chauvinist. Carbon is abundant in the Cosmos. It makes marvelously complex molecules, good for life. I am also a water chauvinist. Water makes an ideal solvent system for organic chemistry to work in and stays liquid over a wide range of temperatures. But sometimes I wonder. Could my fondness for materials have something to do with the fact that I am made chiefly of them? Are we carbon- and water-based because those materials were abundant on the Earth at the time of the origin of life? Could life elsewhere—on Mars, say—be built of different stuff? I am a collection of water, calcium and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label. But is that all? Is there nothing in here but molecules? Some people find this idea somehow demeaning to human dignity. For myself, I find it elevating that our universe permits the evolution of molecular machines as intricate and subtle as we. But the essence of life is not so much the atoms and simple molecules that make us up as the way in which they are put together. Every now and then we read that the chemicals which constitute the human body cost ninety-seven cents or ten dollars or some such figure; it is a little depressing to find our bodies valued so little. However, these estimates are for human beings reduced to our simplest possible components. We are made mostly of water, which costs almost nothing; the carbon is costed in the form of coal; the calcium in our bones as chalk; the nitrogen in our proteins as air (cheap also); the iron in our blood as rusty nails. If we did not know better, we might be tempted to take all the atoms that make us up, mix them together in a big container and stir. We can do this as much as we want. But in the end all we have is a tedious mixture of atoms. How could we have expected anything else? Harold Morowitz has calculated what it would cost to put together the correct molecular constituents that make up a human being by buying the molecules from chemical supply houses. The answer turns out to be about ten million dollars, which should make us all feel a little better. But even then we could not mix those chemicals together and have a human being emerge from the jar. That is far beyond our capability and will probably be so for a very long period of time. Fortunately, there are other less expensive but still highly reliable methods of making human beings. I think the lifeforms on many worlds will consist, by and large, of the same atoms we have here, perhaps even many of the same basic molecules, such as proteins and nucleic acids—but put together in unfamiliar ways. Perhaps organisms that float in dense planetary atmospheres will be very much like us in their atomic composition, except they might not have bones and therefore not need much calcium. Perhaps elsewhere some solvent other than water is used. Hydrofluoric acid might serve rather well, although there is not a great deal of fluorine in the Cosmos; hydrofluoric acid would do a great deal of damage to the kind of molecules that make us up, but other organic molecules, paraffin waxes, for example, are perfectly stable in its presence. Liquid ammonia would make an even better solvent system, because ammonia is very abundant in the Cosmos. But it is liquid only on worlds much colder than the Earth or Mars. Ammonia is ordinarily a gas on Earth, as water is on Venus. Or perhaps there are living things that do not have a solvent system at all—solid-state life, where there are electrical signals propagating rather than molecules floating about. But these ideas do not
