Nitrogen Quotes

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.

We have calcium in our bones, iron in our veins, carbon in our souls, and nitrogen in our brains. 93 percent stardust, with souls made of flames, we are all just stars that have people names.

She is oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. The same elements that are inside the rest of us, but I can’t help thinking she’s more than that and she’s got other elements going on that no one’s ever heard of, ones that make her stand apart from everybody else. I feel this brief panic as I think, What would happen if one of those elements malfunctioned or just stopped working altogether? I make myself push this aside and concentrate on the feel of her skin until I no longer see molecules but Violet.

Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

How Not to Break Into Sublevel Two (A list by Cameron Morgan, with help from Macey McHenry) .... -Teleportation: Sure, Liz says she has an excellent working theory, but she doesn't have a prototype yet. And without a prototype it's pretty much a moot point. -That thing Bex's parents did in Dubai with liquid nitrogen, an earthquake simulator, and a ferret: Because we don't have a ferret.

Grief is an element. It has its own cycle like the carbon cycle, the nitrogen. It never diminishes not ever. It passes in and out of everything.

The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

While an elderly man in his mid-eighties looks curiously at a porno site, his grandson asks him from afar, “‘What are you reading, grandpa?’” “‘It’s history, my boy.’” “The grandson comes nearer and exclaims, “‘But this is a porno site, grandpa, naked chicks, sex . . . a lot of sex!’” “‘Well, it’s sex for you, my son, but for me it’s history,’ the old man says with a sigh.” All of people in the cabin burst into laughter. “A stale joke, but a cool one,” added William More, the man who just told the joke. The navigator skillfully guided the flying disc among the dense orange-yellow blanket of clouds in the upper atmosphere that they had just entered. Some of the clouds were touched with a brownish hue at the edges. The rest of the pilots gazed curiously and intently outwards while taking their seats. The flying saucer descended slowly, the navigator’s actions exhibiting confidence. He glanced over at the readings on the monitors below the transparent console: Atmosphere: Dense, 370 miles thick, 98.4% nitrogen, 1.4% methane Temperature on the surface: ‒179°C / ‒290°F Density: 1.88 g/cm³ Gravity: 86% of Earth’s Diameter of the cosmic body: 3200 miles / 5150 km.

She is oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

The knowledge that the atoms that comprise life on earth - the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars- the high mass ones among them- went unstable in their later years- they collapsed and then exploded- scattering their enriched guts across the galaxy- guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems- stars with orbiting planets. And those planets now have the ingredients for life itself. So that when I look up at the night sky, and I know that yes we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us. When I reflect on that fact, I look up- many people feel small, cause their small and the universe is big. But I feel big because my atoms came from those stars.

You couldn't be here if stars hadn't exploded. Because the elements, the carbon, nitrogen, oxygen, iron, all the things that matter for evolution weren't created at the beginning of time. They were created in the nuclear furnaces of stars. And the only way they could get into your body is if the stars were kind enough to explode. So forget Jesus. The stars died so that you could be here today.

Some people find fall depressing, others hate spring. I've always been a spring person myself. All that growth, you can feel Nature groaning, the old bitch; she doesn't want to do it, not again, no, anything but that, but she has to. It's a fucking torture rack, all that budding and pushing, the sap up the tree trunks, the weeds and the insects getting set to fight it out once again, the seeds trying to remember how the hell the DNA is supposed to go, all that competition for a little bit of nitrogen; Christ, it's cruel.

I wanted to cry. I also wanted to go to my laboratory and prepare an enormous batch of nitrogen triiodide with which to blow up, in a spectacular mushroom cloud of purple vapor, the world and everyone in it.

The four most common chemically active elements in the universe—hydrogen, oxygen, carbon, and nitrogen—are the four most common elements of life on Earth. We are not simply in the universe. The universe is in us.

She is oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. The same elements that are inside the rest of us, but I can't help thinking she's more that that and she's got other elements going on that on one's ever heard of, ones that make her stand apart from everybody else.

Alex shot her a look that was colder than liquid nitrogen.

Stars are made of dust and nitrogen; they are balls of gas and hydrogen. But that isn’t what a star is; it’s only what it is made of.

There is a fundamental reason why we look at the sky with wonder and longing—for the same reason that we stand, hour after hour, gazing at the distant swell of the open ocean. There is something like an ancient wisdom, encoded and tucked away in our DNA, that knows its point of origin as surely as a salmon knows its creek. Intellectually, we may not want to return there, but the genes know, and long for their origins—their home in the salty depths. But if the seas are our immediate source, the penultimate source is certainly the heavens… The spectacular truth is—and this is something that your DNA has known all along—the very atoms of your body—the iron, calcium, phosphorus, carbon, nitrogen, oxygen, and on and on—were initially forged in long-dead stars. This is why, when you stand outside under a moonless, country sky, you feel some ineffable tugging at your innards. We are star stuff. Keep looking up.

The Qur’an is a book with enormous power. When not understood properly, it can yield perilous results—similar to how powerful natural elements like hydrogen, nitrogen, and oxygen are vital components of air, soil, and water, yet can also be manipulated to manufacture explosives.

He'd heard about people who ascended too quickly and developed nitrogen bubbles in their blood. Leo wanted to avoid carbonated blood.

We're all made of stardust Mr. Strickland. Oxygen, hydrogen, carbon, nitrogen, and calcium. If some of us get our way and our Countries fire off their warheads, then we shall return to stardust. All of us. And what color will our stars be then? That is the question. A question you might ask yourself.

All the green in the planted world consists of these whole, rounded chloroplasts wending their ways in water. If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring's center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its exact place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish's tail.

Your topsoil's a disaster area — it's starved for nitrogen, it's been fertilized for years by the criminally insane, and whatever thief put in your irrigation system ought to be flogged through the fleet.

How strange that so few people ever looked up from the spice long enough to wonder at the near-ideal nitrogen-oxygen-CO2 balance being maintained here in the absence of large areas of plant cover.

I’ll drop the oxygen mixture to zero and breathe pure nitrogen until I suffocate. It wouldn’t feel bad. The lungs don’t have the ability to sense lack of oxygen. I’d just get tired, fall asleep, then die.

There is evidence that the honoree [Leonard Cohen] might be privy to the secret of the universe, which, in case you're wondering, is simply this: everything is connected. Everything. Many, if not most, of the links are difficult to determine. The instrument, the apparatus, the focused ray that can uncover and illuminate those connections is language. And just as a sudden infatuation often will light up a person's biochemical atmosphere more pyrotechnically than any deep, abiding attachment, so an unlikely, unexpected burst of linguistic imagination will usually reveal greater truths than the most exacting scholarship. In fact. The poetic image may be the only device remotely capable of dissecting romantic passion, let alone disclosing the inherent mystical qualities of the material world. Cohen is a master of the quasi-surrealistic phrase, of the "illogical" line that speaks so directly to the unconscious that surface ambiguity is transformed into ultimate, if fleeting, comprehension: comprehension of the bewitching nuances of sex and bewildering assaults of culture. Undoubtedly, it is to his lyrical mastery that his prestigious colleagues now pay tribute. Yet, there may be something else. As various, as distinct, as rewarding as each of their expressions are, there can still be heard in their individual interpretations the distant echo of Cohen's own voice, for it is his singing voice as well as his writing pen that has spawned these songs. It is a voice raked by the claws of Cupid, a voice rubbed raw by the philosopher's stone. A voice marinated in kirschwasser, sulfur, deer musk and snow; bandaged with sackcloth from a ruined monastery; warmed by the embers left down near the river after the gypsies have gone. It is a penitent's voice, a rabbinical voice, a crust of unleavened vocal toasts -- spread with smoke and subversive wit. He has a voice like a carpet in an old hotel, like a bad itch on the hunchback of love. It is a voice meant for pronouncing the names of women -- and cataloging their sometimes hazardous charms. Nobody can say the word "naked" as nakedly as Cohen. He makes us see the markings where the pantyhose have been. Finally, the actual persona of their creator may be said to haunt these songs, although details of his private lifestyle can be only surmised. A decade ago, a teacher who called himself Shree Bhagwan Rajneesh came up with the name "Zorba the Buddha" to describe the ideal modern man: A contemplative man who maintains a strict devotional bond with cosmic energies, yet is completely at home in the physical realm. Such a man knows the value of the dharma and the value of the deutschmark, knows how much to tip a waiter in a Paris nightclub and how many times to bow in a Kyoto shrine, a man who can do business when business is necessary, allow his mind to enter a pine cone, or dance in wild abandon if moved by the tune. Refusing to shun beauty, this Zorba the Buddha finds in ripe pleasures not a contradiction but an affirmation of the spiritual self. Doesn't he sound a lot like Leonard Cohen? We have been led to picture Cohen spending his mornings meditating in Armani suits, his afternoons wrestling the muse, his evenings sitting in cafes were he eats, drinks and speaks soulfully but flirtatiously with the pretty larks of the street. Quite possibly this is a distorted portrait. The apocryphal, however, has a special kind of truth. It doesn't really matter. What matters here is that after thirty years, L. Cohen is holding court in the lobby of the whirlwind, and that giants have gathered to pay him homage. To him -- and to us -- they bring the offerings they have hammered from his iron, his lead, his nitrogen, his gold.

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?

I want to end my life like a human being: in Intensive Care, high on morphine, surrounded by cripplingly expensive doctors and brutal, relentless life-support machines. Then the corpse can go into orbit—preferably around the sun. I don't care how much it costs, just so long as I don't end up party of any fucking natural cycle: carbon, phosphorus, nitrogen. Gaia, I divorce thee. Go suck the nutrients out of someone else, you grasping bitch.

Before artificial nitrogen fertilizer became widely available, the world's population was around 2 billion. When we no longer have it - or if we ever decide to stop using it - that may be the number to which our own naturally gravitates.

The God of the universe--the creator of nitrogen and pine needles, galaxies and E-minor--loves us with a radical, unconditional, self-sacrificing love. And what is our typical response? We go to church, sing songs, and try not to cuss.

There was something stunned in the faces of the children, blinking and tentative. The slow, dark, dull submarine of the lives in which they were the human cargo had abruptly surfaced. Their blood was filled with a kind of crippling nitrogen of wonder.

Forest air is the epitome of healthy air. People who want to take a deep breath of fresh air or engage in physical activity in a particularly agreeable atmosphere step out into the forest. There's every reason to do so. The air truly is considerably cleaner under the trees, because the trees act as huge air filters. Their leaves and needles hang in a steady breeze, catching large and small particles as they float by. Per year and square mile this can amount to 20,000 tons of material. Trees trap so much because their canopy presents such a large surface area. In comparison with a meadow of a similar size, the surface area of the forest is hundreds of times larger, mostly because of the size difference between trees and grass. The filtered particles contain not only pollutants such as soot but also pollen and dust blown up from the ground. It is the filtered particles from human activity, however, that are particularly harmful. Acids, toxic hydrocarbons, and nitrogen compounds accumulate in the trees like fat in the filter of an exhaust fan above a kitchen stove. But not only do trees filter materials out of the air, they also pump substances into it. They exchange scent-mails and, of course, pump out phytoncides, both of which I have already mentioned.

I asked the feedlot manager why they didn't just spray the liquefied manure on neighboring farms. The farmers don't want it, he explained. The nitrogen and phosphorus levels are so high that spraying the crops would kill them. He didn't say that feedlot wastes also contain heavy metals and hormone residues, persistent chemicals that end up in waterways downstream, where scientists have found fish and amphibians exhibiting abnormal sex characteristics.

half of its carbon 14 content decays into nitrogen 14 every 5,700 years, until

Plants have to eat, too,” I tried to explain. “They need nitrogen, they need minerals. You have to replace what you’re taking out. Your choices are fossil fuels or animal products.

Once when I was younger I went out and sat under the sky and looked up and asked it to take me back. What I should have done was gone to the swamp and bog and ask them to bring me back because, if anything is, mud and marsh are the origins of life. Now i think of the storm that made chaos, that the storm opened a door. It tried to make over a world the way it wanted it to be. At school I learned that storms create life, that lightning, with its nitrogen, is a beginning; bacteria and enzymes grow new life from decay out of darkness and water. It's into this that I want to fall, into swamp and mud and sludge and it seems like falling is the natural way of things; gravity needs no fuel, no wings. It needs only stillness and waiting and time.

Eventually, when those massive stars reach the end of their lives, they go out with a bang, a supernova so bright, so beautiful it drowns out all the other stars. And when they do, they throw out all those elements they created. That’s what we’re made of. We’ve got calcium in our bones and iron in our blood and nitrogen in our DNA . . . and all of that? It comes from those stars.” Elle’s eyes glistened, sparkling as bright as the stars she spoke of as she blinked and pointed up at the sky. “We are literally made of stardust.

A charge often levied against organic agriculture is that it is more philosophy than science. There's some truth to this indictment, if that it what it is, though why organic farmers should feel defensive about it is itself a mystery, a relic, perhaps, of our fetishism of science as the only credible tool with which to approach nature. ... The peasant rice farmer who introduces ducks and fish to his paddy may not understand all the symbiotic relationships he's put in play--that the ducks and fishes are feeding nitrogen to the rice and at the same time eating the pests. But the high yields of food from this ingenious polyculture are his to harvest even so.

This is what works for me: I practise crop rotation with my creative endeavours. I’ve found that when the nitrogen runs out in the soil in one field, it’s best to leave it fallow for a while and cultivate another.

Whatever else it may be, at the level of chemistry life is curiously mundane: carbon, hydrogen, oxygen, and nitrogen, a little calcium, a dash of sulfur, a light dusting of other very ordinary elements—nothing you wouldn’t find in any ordinary drugstore—and that’s all you need. The only thing special about the atoms that make you is that they make you. That is of course the miracle of life.

You don't usually think of boredom as something similar to pain. That's because you've only been exposed to it in relatively small doses. You don’t know its true colour. The difference between the boredom you know and the boredom I know is like the difference between touching snow and putting your hand in a vat of liquid nitrogen.

Scheele independently discovered eight elements—chlorine, fluorine, manganese, barium, molybdenum, tungsten, nitrogen, and oxygen—but received credit for none of them in his lifetime. He had an unfortunate habit of tasting every substance he worked with, as a way of familiarizing himself with its properties, and eventually the practice caught up with him.

Liquid nitrogen,” said Olaf. “Try not to shoot them.” “Really cold?” “Really explosive.

Why does nitrogen break so often? Because it’s hard to fix! Ha-ha.

But this, too, was a side effect of dying: I could not run or dance or eat foods rich in nitrogen, but in the city of freedom, I was among the most liberated of its residents.

She is oxygen, carbon, nitrogen, calcium and phosphorus. The same elements that are inside the rest of us, but I can't help thinking that she's more than that and she's got other elements going on that no one's ever heard of, ones that make her stand apart from everyone else.

We chattered about the implications for farms: if legumes passed nitrogen to corn, for instance, we could mix crops and stop having to pollute the soil with fertilizers and herbicides.

The term ‘mycorrhiza’ is made from the Greek words for ‘fungus’ and ‘root’. It is itself a collaboration or entanglement; and as such a reminder of how language has its own sunken system of roots and hyphae, through which meaning is shared and traded. The relationship between mycorrhizal fungi and the plants they connect is ancient – around 450 million years old – and largely one of mutualism. In the case of the tree–fungi mutualism, the fungi siphon off carbon that has been produced in the form of glucose by the trees during photosynthesis, by means of chlorophyll that the fungi do not possess. In turn, the trees obtain nutrients such as phosphorus and nitrogen that the fungi have acquired from the soil through which they grow, by means of enzymes that the trees lack.

It is an atmosphere peculiar to the place; and, because of it, the sunshine in Horai is whiter than any other sunshine, - a milky light that never dazzles, - astonishingly clear, but very soft. This atmosphere is not of our human period: it is enormously old, - so old that I feel afraid when I try to think how old it is; - and it is not a mixture of nitrogen and oxygen. It is not made of air at all, but of ghost, - the substance of quintillions of quintillions of generations of souls blended into one immense translucency, - souls of people who thought in ways never resembling our ways.

In 1999 the RAND Corporation published a report (the first and, so far, last of its kind) with a “conservative estimate” that more than 307 million tissue samples from more than 178 million people were stored in the United States alone. This number, the report said, was increasing by more than 20 million samples each year. The samples come from routine medical procedures, tests, operations, clinical trials, and research donations. They sit in lab freezers, on shelves, or in industrial vats of liquid nitrogen. They’re stored at military facilities, the FBI, and the National Institutes of Health.

The doctors removed my wasteland exterior by debriding me, scraping away the charred flesh. they brought in tanks of liquid nitrogen containing skin recently harvested from corpses. The sheets were thawed in pans of water, then neatly arranged on my back and stapled into place. Just like that, as if they were laying strips of sod over the problem areas behind their summer cabins, they wrapped me in the skin of the dead. My body was cleaned constantly but I rejected these sheets of necro-flesh anyway; I've never played well with others. So over and over again, I was sheeted with cadaver skin.

Asking someone else to drive your sports car is like asking someone else to kiss your girlfriend.

I am plant as well as animal. My blood transports oxygen; my chlorophyll produces it. Oxygen, carbon, hydrogen, nitrogen, phosphorus surge along tissue, torso, culm to my blades. Blood blends magnesium as well as iron. I am grass made flesh. Grassling.

You may have heard that "we are made of stardust" (or "star stuff" if you're Sagan), and this is absolutely true if we measure by mass. All the heavier elements in your body—oxygen, carbon, nitrogen, calcium, etc.—were produced later, either in the centers of stars or in stellar explosions. But hydrogen, while the lightest, is also the most abundant element in your body by number. So, yes, you hold within you the dust of ancient generations of stars. But you are also, to a very large fraction, built out of by-products of the actual Big Bang. Carl Sagan's larger statement still stands, and to an even larger degree: "We are a way for the cosmos to know itself.

The four most common, chemically active elements in the universe—hydrogen, oxygen, carbon, and nitrogen—are the four most common elements of life on Earth, with carbon serving as the foundation of biochemistry. We do not simply live in this universe. The universe lives within us.

• Human activity has transformed between a third and a half of the land surface of the planet. • Most of the world’s major rivers have been dammed or diverted. • Fertilizer plants produce more nitrogen than is fixed naturally by all terrestrial ecosystems. • Fisheries remove more than a third of the primary production of the oceans’ coastal waters. • Humans use more than half of the world’s readily accessible fresh water runoff.

Eventually decomposition strips you bare, even in that solid oak you've taken the shape of. You've helped, finally, to enrich something around you, by feeding the soil with your skin and fat and muscle. Now the soil is full of phosphorus, potassium, calcium, and especially nitrogen. Now the soil is supremely satisfied, and you'd be okay with that. You always did like growing things. You always were better with plants than people.

A soaking rain had just stopped, and his boots sank deeply into the nitrogen-rich soil. The entire orchard smelled of wet wood and ripe fruit. It was a strong dizzying scent, and nothing else was quite like it- though his grandfather used to say this smell was identical to the limestone caves of Lower Normandy: cold and dripping, where cask upon cask of Calvados, the great fortified apple brandy of Norman lords, slept away the years.

There needs to be an intersection of the set of people who wish to go, and the set of people who can afford to go...and that intersection of sets has to be enough to establish a self-sustaining civilisation. My rough guess is that for a half-million dollars, there are enough people that could afford to go and would want to go. But it’s not going to be a vacation jaunt. It’s going to be saving up all your money and selling all your stuff, like when people moved to the early American colonies...even at a million people you’re assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars. You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil.Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we’re talking 100,000 trips of a giant spaceship...If we can establish a Mars colony, we can almost certainly colonise the whole Solar System, because we’ll have created a strong economic forcing function for the improvement of space travel. We’ll go to the moons of Jupiter, at least some of the outer ones for sure, and probably Titan on Saturn, and the asteroids. Once we have that forcing function, and an Earth-to-Mars economy, we’ll cover the whole Solar System. But the key is that we have to make the Mars thing work. If we’re going to have any chance of sending stuff to other star systems, we need to be laser-focused on becoming a multi-planet civilisation. That’s the next step.

In the narrow thread of sod between the shaved banks and the toppling fences grow the relics of what once was Illinois — the prairie. No one in the bus sees these relics. A worried farmer, his fertilizer bill projecting from his shirt pocket, looks blankly at the lupines, lespedezas or Baptisias that originally pumped nitrogen out of the prairie air and into his black loamy acres. He does not distinguish them from the parvenu quack-grass in which they grow. Were I to ask him the name of that white spike of pea-like flowers hugging the fence, he would shake his head. A weed, likely.

I think of two landscapes- one outside the self, the other within. The external landscape is the one we see-not only the line and color of the land and its shading at different times of the day, but also its plants and animals in season, its weather, its geology… If you walk up, say, a dry arroyo in the Sonoran Desert you will feel a mounding and rolling of sand and silt beneath your foot that is distinctive. You will anticipate the crumbling of the sedimentary earth in the arroyo bank as your hand reaches out, and in that tangible evidence you will sense the history of water in the region. Perhaps a black-throated sparrow lands in a paloverde bush… the smell of the creosote bush….all elements of the land, and what I mean by “the landscape.” The second landscape I think of is an interior one, a kind of projection within a person of a part of the exterior landscape. Relationships in the exterior landscape include those that are named and discernible, such as the nitrogen cycle, or a vertical sequence of Ordovician limestone, and others that are uncodified or ineffable, such as winter light falling on a particular kind of granite, or the effect of humidity on the frequency of a blackpoll warbler’s burst of song….the shape and character of these relationships in a person’s thinking, I believe, are deeply influenced by where on this earth one goes, what one touches, the patterns one observes in nature- the intricate history of one’s life in the land, even a life in the city, where wind, the chirp of birds, the line of a falling leaf, are known. These thoughts are arranged, further, according to the thread of one’s moral, intellectual, and spiritual development. The interior landscape responds to the character and subtlety of an exterior landscape; the shape of the individual mind is affected by land as it is by genes. Among the Navajo, the land is thought to exhibit sacred order…each individual undertakes to order his interior landscape according to the exterior landscape. To succeed in this means to achieve a balanced state of mental health…Among the various sung ceremonies of this people-Enemyway, Coyoteway, Uglyway- there is one called Beautyway. It is, in part, a spiritual invocation of the order of the exterior universe, that irreducible, holy complexity that manifests itself as all things changing through time (a Navajo definition of beauty).

When I was Downtown, I learned a lot about making threats. Make them big. Make them outrageous. You're never going to kick someone's ass. You're going to pull out their tongue and pour liquid nitrogen down their throat, chip out their guts with an ice pick, slide in a pane of glass, and turn them into an aquarium.

How does the living organism avoid decay? The obvious answer is: By eating, drinking, breathing and (in the case of plants) assimilating. The technical term is metabolism. The Greek word () means change or exchange. Exchange of what? Originally the underlying idea is, no doubt, exchange of material. (E.g. the German for metabolism is Stoffwechsel.) That the exchange of material should be the essential thing is absurd. Any atom of nitrogen, oxygen, sulphur, etc., is as good as any other of its kind; what could be gained by exchanging them? For a while in the past our curiosity was silenced by being told that we feed upon energy.

What is the most astounding fact you can share with us about the Universe? "The most astounding fact is the knowledge that the atoms that comprise life on Earth. The atoms that make up the human body are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars, the high mass ones among them went unstable in their later years. They collapsed and then exploded, scattering their enriched guts across the galaxy. Guts made of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems. Stars with orbiting planets, and those planets now have the ingredients for life itself. So that when I look up at the night sky and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up – many people feel small because they’re small and the Universe is big – but I feel big, because my atoms came from those stars. There’s a level of connectivity. That’s really what you want in life, you want to feel connected, you want to feel relevant you want to feel like you’re a participant in the goings on of activities and events around you. That’s precisely what we are, just by being alive…

Caffeine is made of carbon, hydrogen, nitrogen and oxygen: the same as cocaine, thalidomide, nylon, TNT and heroin.

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff

It wouldn’t be so bad if the MAV blew up. I wouldn’t know what hit me, but if I miss the intercept, I’ll just float around in space until I run out of air. I have a contingency plan for that. I’ll drop the oxygen mixture to zero and breathe pure nitrogen until I suffocate. It wouldn’t feel bad. The lungs don’t have the ability to sense lack of oxygen. I’d just get tired, fall asleep, then die.

He will be lowered into a vat of liquid nitrogen and frozen. From here he will progress to the second chamber, where either ultrasound waves or mechanical vibration will be used to break his easily shattered self* into small pieces, more or less the size of ground chuck. The pieces, still frozen, will then be freeze-dried and used as compost for a memorial tree or shrub, either in a churchyard memorial park or in the family’s yard.

...-compost is trucked in; some crops also receive fish emulsion along with their water and a side dressing of pelleted chicken manure. Over the winter a cover crop of legumes is planted to build up nitrogen in the soil.

Dr. Ashley King, planetary scientist and stardust expert (an enviable job description), states: “It is totally 100 percent true: nearly all the elements in the human body were made in a star and many have come through several supernovas.” Oxygen + carbon + hydrogen + nitrogen + calcium + phosphorous + potassium + sulfur + sodium + chlorine + magnesium = star-human. The stuff of the cosmos is woven into our bone branches and wanders in our blood rivers.

21. Take in a great breath of air and then blow it out. Contained in that single breath were at least three nitrogen atoms that were breathed by every human being who ever lived, including Jesus Christ, William Shakespeare, Winston Churchill, and every president of the United States. This illustrates the fact that everything we do affects other people, positively or negatively. That’s why it is foolish to say, “Do your own thing if it doesn’t hurt anybody else.” Everything we do affects other people.

In 1999 the National Research Council concluded that 'the total exposure to naturally occurring carcinogens exceeds the exposure to synthetic carcinogens.'... The point was that even if organics were pesticide-free, the gain wouldn't make up for the downside of organic food: It's more likely to be infested with bacteria because it's grown in 'natural' fertilizer. Natural fertilizer is the health food business's euphemism for cow manure. (The much-criticized 'nonorganic' produce is grown in nitrogen fertilizers. Although organics advocates sneer at the chemicals, 'chemical' nitrogen is perfectly healthy; air is 78 percent nitrogen, after all. We have a choice between foods grown in nitrogen taken from the air, and 'organic' food grown in cow manure.)

The cornstalks act as supports for the climbing beans, the beans fix nitrogen in the soil for the corn and squash, and the squash provides mulch and root protection for the corn and beans. And then, just to make it all perfect, when you eat the corn and beans together, they form a complete protein.

Men presumably always have looked at flowers and been moved by their beauty and their smell: but only since the last century has it been possible to take a flower in your hand and know that you have between your fingers a complex association of organic compounds containing carbon, hydrogen, oxygen, nitrogen, phosphorus, and a great many other elements, in a complex structure of cells, all of which have evolved from a single cell; and to know something of the internal structure of these cells, and the processes by which they evolved, and the genetic process by which this flower was begun, and will produce other flowers; to know in detail how the light from it is reflected to your eye; and to know the details of those workings of your eye, and your nose, and your neurophysiological system, which enable you to see and smell and touch the flower. These inexhaustible and almost incredible realities which are all around us and within us are recent discoveries which are still being explored, while similar new discoveries continue to be made; and we have before us an endless vista of such new possibilities stretching into the future, all of it beyond man’s wildest dreams until almost the age we ourselves are living in. Popper’s ever present and vivid sense of this, and of the fact that every discovering opens up new problems for us, informs his theoretical methodology. He knows that our ignorance grows with our knowledge, and that we shall therefore always have more questions than answers.

Trees for which there is no commercial value are referred to as "weeds" that interfere with commercial harvesting. That's what alders were called until a method to make high-grade paper from them was developed, but you'd never know that alders play an important ecological role. They are the first trees to grow after an opening is cleared in a forest, and they fix nitrogen from the air to fertilize the soil for the later-growing, longer-lived, bigger tree species. Yew trees have tough wood with gnarled branches and were called weeds and burned until a powerful anti-cancer agent was found in their bark.

Artists don't think outside the box, because outside the box there's a vacumm. Outside the box there are no rules, there is no reality. You have nothing to interact with, nothing to work against. If you set out to do something way outside the box (designing a time machine, or using liquid nitrogen to freeze Niagara Falls), then you'll never be able to do the real work of art. You can't ship if you're far outside the box. Artists think along the edges of the box, because that's where things get done. That's where the audience is, that's where the means of production are available, and that's where you can make impact.

Crutzen wrote up his idea in a short essay, “Geology of Mankind,” that ran in Nature. “It seems appropriate to assign the term ‘Anthropocene’ to the present, in many ways human-dominated, geological epoch,” he observed. Among the many geologic-scale changes people have effected, Crutzen cited the following: • Human activity has transformed between a third and a half of the land surface of the planet. • Most of the world’s major rivers have been dammed or diverted. • Fertilizer plants produce more nitrogen than is fixed naturally by all terrestrial ecosystems. • Fisheries remove more than a third of the primary production of the oceans’ coastal waters. • Humans use more than half of the world’s readily accessible fresh water runoff. Most significantly, Crutzen said, people have altered the composition of the atmosphere. Owing to a combination of fossil fuel combustion and deforestation, the concentration of carbon dioxide in the air has risen by forty percent over the last two centuries, while the concentration of methane, an even more potent greenhouse gas, has more than doubled. “Because of these anthropogenic emissions,” Crutzen wrote, the global climate is likely to “depart significantly from natural behavior for many millennia to come.

In the Amazon, the turn to swidden was unfortunate. Slash-and-burn cultivation has become one of the driving forces behind the loss of tropical forest. Although swidden does permit the forest to regrow, it is wildly inefficient and environmentally unsound. The burning sends up in smoke most of the nutrients in the vegetation—almost all of the nitrogen and half the phosphorus and potassium. At the same time, it pours huge amounts of carbon dioxide into the air, a factor in global warming. (Large cattle ranches are the major offenders in the Amazon, but small-scale farmers are responsible for up to a third of the clearing.) Fortunately, it is a relatively new practice, which means it has not yet had much time to cause damage. More important, the very existence of so much healthy forest after twelve thousand years of use by large populations suggests that whatever Indians did before swidden must have been ecologically more sustainable.

In 1907, Haber was the first to obtain nitrogen, the main nutrient required for plant growth, directly from the air. In this way, from one day to the next, he addressed the scarcity of fertilizer that threatened to unleash an unprecedented global famine at the beginning of the twentieth century. Had it not been for Haber, hundreds of millions of people who until then had depended on natural fertilizers such as guano and saltpetre for their crops would have died from lack of nourishment. In prior centuries, Europe’s insatiable hunger had driven bands of Englishmen as far as Egypt to despoil the tombs of the ancient pharaohs, in search not of gold, jewels or antiquities, but of the nitrogen contained in the bones of the thousands of slaves buried along with the Nile pharaohs, as sacrificial victims, to serve them even after their deaths. The English tomb raiders had exhausted the reserves in continental Europe; they dug up more than three million human skeletons, along with the bones of hundreds of thousands of dead horses that soldiers had ridden in the battles of Austerlitz, Leipzig and Waterloo, sending them by ship to the port of Hull in the north of England, where they were ground in the bone mills of Yorkshire to fertilize the verdant fields of Albion.

Chloroplasts bear chlorophyll; they give the green world its color, and they carry out the business of photosynthesis. Around the inside perimeter of each gigantic cell trailed a continuous loop of these bright green dots. They spun . . . they pulsed, pressed, and thronged . . . they shone, they swarmed in ever-shifting files around and around the edge of the cell; they wandered, they charged, they milled, raced . . . they flowed and trooped greenly . . . All the green in the planted world consists of these whole, rounded chloroplasts . . . If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring’s center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish’s tail.

When light from the sun enters the Earth’s atmosphere, it hits all sorts of molecules (mostly nitrogen and oxygen molecules) on its way to Earth and bounces off them like a pinball. This is called scattering, which means that on a clear day, if you look at any part of the sky, the light you see has been bouncing around the atmosphere before coming into your eye. If all light was scattered equally, the sky would look white. But it doesn’t. The reason is that the shorter wavelengths of light are more likely to be scattered than the longer ones, which means that blues get bounced around the sky more than reds and yellows. So instead of seeing a white sky when we look up, we see a blue one.

On the far side of the bay was the command station that controlled the door, which was currently semi-open. Rather than the normal closed maw of steel, there was a network of pulsing gold veins crisscrossing the gaping mouth of black - a nitrogen membrane keeping the molecular air contained and pressurized while allowing aircraft to pass through.

it is terrible and strange to think about all the men and all the women who have nothing to tell, and who imagine no future fate other than to dissolve into a vague biological and technical continuum (because ashes are technical; even when they are only destined to become fertiliser you have to assess their potassium and nitrogen levels); all those people, in short, whose lives have played out without external incident, and who leave life without thinking about it, as one leaves a holiday home that was just fine, without, however, having an idea of a final destination, with just that vague intuition that it would have been preferable not to have been born – well, now I’m talking about the majority of men and women.

Do you know what it feels like right before lightning strikes? How you can feel the current running through your veins? The trembles of warning that ripple through the dense air? The crackling energy that bristles across your skin and shakes you to your bones? It’s as if nitrogen and oxygen have come alive. As if every element in the air is combustible. Explosive.

When the Earth was only about a third of its eventual size, it was probably already beginning to form an atmosphere, mostly of carbon dioxide, nitrogen, methane and sulphur. Hardly the sort of stuff that we would associate with life, and yet from this noxious stew life formed. Carbon dioxide is a powerful greenhouse gas. This was a good thing, because the Sun was significantly dimmer back then. Had we not had the benefit of a greenhouse effect, the Earth might well have frozen over permanently25, and life might never have got a toehold. But somehow life did. For the next 500 million years the young Earth continued to be pelted relentlessly by comets, meteorites and other galactic debris, which brought water to fill the oceans and the components necessary for the successful formation of life. It was a singularly hostile environment, and yet somehow life got going. Some tiny bag of chemicals twitched and became animate. We were on our way. Four billion years later, people began to wonder how it had all happened.

The Yogi practices exercises by which he attains control of his body, and is enabled to send to any organ or part an increased flow of vital force or “prana,” thereby strengthening and invigorating the part or organ. He knows all that his Western scientific brother knows about the physiological effect of correct breathing, but he also knows that the air contains more than oxygen and hydrogen and nitrogen, and that something more is accomplished than the mere oxygenating of the blood. He knows something about “prana,” of which his Western brother is ignorant, and he is fully aware of the nature and manner of handling that great principle of energy, and is fully informed as to its effect upon the human body and mind. He knows that by rhythmical breathing one may bring himself into harmonious vibration with nature, and aid in the unfoldment of his latent powers. He knows that by controlled breathing he may not only cure disease in himself and others, but also practically do away with fear and worry and the baser emotions.

The plant roots enter into symbiotic relationships with bacteria, fungi, and other plants that are highly sophisticated. Bacteria form colonies on roots systems and produce nitrogen nodules, which the plant can then use as a nitrogen source, something the plants cannot do on their own. And in exchange the bacteria gain nutrients they need to survive. Roots also form close attachments with fungal mycelia. In fact, most plant roots are part of a sophisticated root/fungus communal network that can extend over miles.

By one billion years ago, plants, working cooperatively, had made a stunning change in the environment of the Earth. Green plants generate molecular oxygen. Since the oceans were by now filled with simple green plants, oxygen was becoming a major constituent of the Earth’s atmosphere, altering it irreversibly from its original hydrogen-rich character and ending the epoch of Earth history when the stuff of life was made by nonbiological processes. But oxygen tends to make organic molecules fall to pieces. Despite our fondness for it, it is fundamentally a poison for unprotected organic matter. The transition to an oxidizing atmosphere posed a supreme crisis in the history of life, and a great many organisms, unable to cope with oxygen, perished. A few primitive forms, such as the botulism and tetanus bacilli, manage to survive even today only in oxygen-free environments. The nitrogen in the Earth’s atmosphere is much more chemically inert and therefore much more benign than oxygen. But it, too, is biologically sustained. Thus, 99 percent of the Earth’s atmosphere is of biological origin. The sky is made by life.

All the books and instructions insist that the selection of the soil is the most important part of gardening. No doubt it is. But, if a man has already selected his own backyard before he opens the book, what remedy is there? All the books lay stress on the need of "a deep, friable loam full of nitrogen." This I have never seen. My own plot of land I found on examination to contain nothing but earth. I could see no trace of nitrogen. I do not deny the existence of loam. There may be such a thing. But I am admitting now in all humility of mind that I don't know what loam is.

We discover the bumps are milpa, small mounds of earth on which complementary crops were planted. Unlike linear plowing, which encourages water runoff and soil erosion, the circular pattern traps rainfall. Each mound is planted with a cluster of the Three Sisters that were the staples of Indian agriculture: corn, beans, and squash. The corn provided a stalk for the beans to climb, while also shading the vulnerable beans. The ground cover from the squash stabilized the soil, and the bean roots kept the soil fertile by providing nitrogen. As a final touch, marigolds and other natural pesticides were planted around each mound to keep harmful insects away. Altogether it was a system so perfect that in some Central American countries too poor to adopt linear plowing with machinery, artificial pesticides, and monocrops of agribusiness, the same milpa have been producing just fine for four thousand years. 19 Not only that, but milpa can be planted in forests without clear-cutting the trees; at most, by removing a few branches to let sunlight through on a mound. This method was a major reason why three-fifths of all food staples in the world were developed in the Americas.

If the cultural standing of excrement doesn't convince them, I say that the material itself is as rich as oil and probably more useful. It contains nitrogen and phosphates that can make plants grow and also suck the life from water because its nutrients absorb available oxygen. It can be both food and poison. It can contaminate and cultivate. Millions of people cook with gas made by fermenting it. I tell them that I don't like to call it "waste," when it can be turned into bricks, when it can make roads or jewelry, and when in a dried powdered form known as poudrette it was sniffed like snuff by the grandest ladies of the eighteenth-century French court. Medical men of not too long ago thought stool examination a vital diagnostic tool (London's Wellcome Library holds a 150-year0old engraving of a doctor examining a bedpan and a sarcastic maid asking him if he'd like a fork). They were also fond of prescribing it: excrement could be eaten, drunk, or liberally applied to the skin. Martin Luther was convinced: he reportedly ate a spoonful of his own excrement daily and wrote that he couldn't understand the generosity of a God who freely gave such important and useful remedies.

Organic farming is environmentally friendlier to every acre of land. But it requires _more_ acres. The trade-off is a harsh one. Would we rather have pesticides on farmland and nitrogen runoffs from them? Or would we rather chop down more forest? How much more forest would we have to chop down? If we wanted to reduce pesticide use and nitrogen runoff by turning all of the world’s farmland to organic farming, we’d need about 50 percent more farmland than we have today. Nobel Prize winner Norman Borlaug, whose work helped triple crop yields over the last fifty years and arguably saved billions from starvation, estimates that the world would need an _additional_ 5 to 6 billion head of cattle to produce enough manure to fertilize that farmland. There are only an estimated 1.3 billion cattle on the planet today. Combined, we’d need to chop down roughly half of the world’s remaining forest to grow crops and to graze cattle that produce enough manure to fertilize those crops. Clearing that much land would produce around 500 billion tons of CO2, or almost as much as the total cumulative CO2 emissions of the world thus far. And the cattle needed to fertilize that land would produce far _more_ greenhouse gases, in the form of methane, than all of agriculture does today, possibly enough to equal all human greenhouse gases emitted from all sources today. That’s not a viable path.

About 4.6 billion years ago, a great swirl of gas and dust some 15 billion miles across accumulated in space where we are now and began to aggregate. Virtually all of it—99.9 percent of the mass of the solar system—went to make the Sun. Out of the floating material that was left over, two microscopic grains floated close enough together to be joined by electrostatic forces. This was the moment of conception for our planet. All over the inchoate solar system, the same was happening. Colliding dust grains formed larger and larger clumps. Eventually the clumps grew large enough to be called planetesimals. As these endlessly bumped and collided, they fractured or split or recombined in endless random permutations, but in every encounter there was a winner, and some of the winners grew big enough to dominate the orbit around which they traveled. It all happened remarkably quickly. To grow from a tiny cluster of grains to a baby planet some hundreds of miles across is thought to have taken only a few tens of thousands of years. In just 200 million years, possibly less, the Earth was essentially formed, though still molten and subject to constant bombardment from all the debris that remained floating about. At this point, about 4.5 billion years ago, an object the size of Mars crashed into Earth, blowing out enough material to form a companion sphere, the Moon. Within weeks, it is thought, the flung material had reassembled itself into a single clump, and within a year it had formed into the spherical rock that companions us yet. Most of the lunar material, it is thought, came from the Earth’s crust, not its core, which is why the Moon has so little iron while we have a lot. The theory, incidentally, is almost always presented as a recent one, but in fact it was first proposed in the 1940s by Reginald Daly of Harvard. The only recent thing about it is people paying any attention to it. When Earth was only about a third of its eventual size, it was probably already beginning to form an atmosphere, mostly of carbon dioxide, nitrogen, methane, and sulfur. Hardly the sort of stuff that we would associate with life, and yet from this noxious stew life formed. Carbon dioxide is a powerful greenhouse gas.

Funny thing about Gabby: you wouldn’t know it from looking at him, with his golden halo and platonic beauty, but the guy was something of a pack rat. He’d been collecting little odds and ends since at least the double-digit redshifts. The interior reality of Gabriel’s Magisterium burbled and shifted like convection currents in a star on the zaftig end of the main sequence. Because, I realized, that’s what they were. Dull dim light, from IR to X-ray, oozed past me like the wax in a million-mile lava lamp while carbon, nitrogen, and oxygen nuclei did little do-si-dos about my toes. Every bubble, every sizzle, every new nucleus, every photodissociation tagged something of interest to Gabriel. The heart of this star smelled of roses and musty libraries.

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

The more important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplanted in consequence of new discoveries is exceedingly remote. Nevertheless, it has been found that there are apparent exceptions to most of these laws, and this is particularly true when the observations are pushed to a limit, i.e., whenever the circumstances of experiment are such that extreme cases can be examined. Such examination almost surely leads, not to the overthrow of the law, but to the discovery of other facts and laws whose action produces the apparent exceptions. As instances of such discoveries, which are in most cases due to the increasing order of accuracy made possible by improvements in measuring instruments, may be mentioned: first, the departure of actual gases from the simple laws of the so-called perfect gas, one of the practical results being the liquefaction of air and all known gases; second, the discovery of the velocity of light by astronomical means, depending on the accuracy of telescopes and of astronomical clocks; third, the determination of distances of stars and the orbits of double stars, which depend on measurements of the order of accuracy of one-tenth of a second-an angle which may be represented as that which a pin's head subtends at a distance of a mile. But perhaps the most striking of such instances are the discovery of a new planet or observations of the small irregularities noticed by Leverrier in the motions of the planet Uranus, and the more recent brilliant discovery by Lord Rayleigh of a new element in the atmosphere through the minute but unexplained anomalies found in weighing a given volume of nitrogen. Many other instances might be cited, but these will suffice to justify the statement that 'our future discoveries must be looked for in the sixth place of decimals.

Ocean Acidification is sometimes referred to as Global Warming's Equally Evil Twin. The irony is intentional and fair enough as far as it goes... No single mechanism explains all the mass extinctions in the record and yet changes in ocean chemistry seem to be a pretty good predictor. Ocean Acidification played a role in at least 2 of the Big Five Extinctions: the End-Permian and the End-Triassic. And quite possibly it was a major factor in a third, the End-Cretaceous. ...Why is ocean acidification so dangerous? The question is tough to answer only because the list of reasons is so long. Depending on how tightly organisms are able to regulate their internal chemistry, acidification may affect such basic processes as metabolism, enzyme activity, and protein function. Because it will change the makeup of microbial communities, it will alter the availability of key nutrients, like iron and nitrogen. For similar reasons, it will change the amount of light that passes through the water, and for somewhat different reasons, it will alter the way sound propagates. (In general, acidification is expected to make the seas noisier.) It seems likely to promote the growth of toxic algae. It will impact photosynthesis—many plant species are apt to benefit from elevated CO2 levels—and it will alter the compounds formed by dissolved metals, in some cases in ways that could be poisonous. Of the myriad possible impacts, probably the most significant involves the group of creatures known as calcifiers. (The term calcifier applies to any organism that builds a shell or external skeleton or, in the case of plants, a kind of internal scaffolding out of the mineral calcium carbonate.)... Ocean acidification increases the cost of calcification by reducing the number of carbonate ions available to organisms that build shells or exoskeletons. Imagine trying to build a house while someone keeps stealing your bricks. The more acidified the water, the greater the energy that’s required to complete the necessary steps. At a certain point, the water becomes positively corrosive, and solid calcium carbonate begins to dissolve. This is why the limpets that wander too close to the vents at Castello Aragonese end up with holes in their shells. According to geologists who work in the area, the vents have been spewing carbon dioxide for at least several hundred years, maybe longer. Any mussel or barnacle or keel worm that can adapt to lower pH in a time frame of centuries presumably already would have done so. “You give them generations on generations to survive in these conditions, and yet they’re not there,” Hall-Spencer observed.

About 4.6 billion years ago, a great swirl of gas and dust some 24 billion kilometres across accumulated in space where we are now and began to aggregate. Virtually all of it – 99.9 per cent of the mass of the solar system21 – went to make the Sun. Out of the floating material that was left over, two microscopic grains floated close enough together to be joined by electrostatic forces. This was the moment of conception for our planet. All over the inchoate solar system, the same was happening. Colliding dust grains formed larger and larger clumps. Eventually the clumps grew large enough to be called planetesimals.

In just 200 million years, possibly less22, the Earth was essentially formed, though still molten and subject to constant bombardment from all the debris that remained floating about. At this point, about 4.4 billion years ago, an object the size of Mars crashed into the Earth, blowing out enough material to form a companion sphere, the Moon. Within weeks, it is thought, the flung material had reassembled itself into a single clump, and within a year it had formed into the spherical rock that companions us yet. Most of the lunar material, it is thought, came from the Earth’s crust, not its core23, which is why the Moon has so little iron while we have a lot.

You are God. You want to make a forest, something to hold the soil, lock up energy, and give off oxygen. Wouldn’t it be simpler just to rough in a slab of chemicals, a green acre of goo? You are a man, a retired railroad worker who makes replicas as a hobby. You decide to make a replica of one tree, the longleaf pine your great-grandfather planted- just a replica- it doesn’t have to work. How are you going to do it? How long do you think you might live, how good is your glue? For one thing, you are going to have to dig a hole and stick your replica trunk halfway to China if you want the thing to stand up. Because you will have to work fairly big; if your replica is too small, you’ll be unable to handle the slender, three-sided needles, affix them in clusters of three in fascicles, and attach those laden fascicles to flexible twigs. The twigs themselves must be covered by “many silvery-white, fringed, long-spreading scales.” Are your pine cones’ scales “thin, flat, rounded at the apex?” When you loose the lashed copper wire trussing the limbs to the trunk, the whole tree collapses like an umbrella. You are a sculptor. You climb a great ladder; you pour grease all over a growing longleaf pine. Next, you build a hollow cylinder around the entire pine…and pour wet plaster over and inside the pine. Now open the walls, split the plaster, saw down the tree, remove it, discard, and your intricate sculpture is ready: this is the shape of part of the air. You are a chloroplast moving in water heaved one hundred feet above ground. Hydrogen, carbon, oxygen, nitrogen in a ring around magnesium…you are evolution; you have only begun to make trees. You are god- are you tired? Finished?

May I ask you a question? If you have to hold your breath too long, what is it that makes you desperate to breathe again?” “I’m running out of oxygen, I guess.” “That’s the interesting fact. It isn’t the absence of oxygen. It’s the presence of carbon dioxide. Kind of the same thing, but not exactly. The point is, you could suck up any kind of gas, and as long as it wasn’t carbon dioxide, your brain would be happy. You could have a chest full of nitrogen, no oxygen at all, about to kill you stone dead, and your lungs would say, hey man, we’re cool, no carbon dioxide here, no need for us to start pumping again until we see some. Which they never will, because you’ll never breathe again. Because you’ll never need to. Because you have no carbon dioxide. And so on. So those folks started sniffing nitrogen, but you have to go to the welding shop and the cylinders are too heavy to lift, so then they tried helium from the balloon store, but you needed masks and tubes, and the whole thing still looks weird, so in the end most folks won’t be satisfied with anything less than the old-fashioned bottle of pills and the glass of scotch. Exactly like it used to be. Except it can’t be anymore. Those pills were most likely either Nembutal or Seconal, and both of those substances are tightly controlled now. There’s no way to get them. Except illegally, of course, way down where no one can see you. There are sources. The holy grail. Most of the offers are scams, naturally. Powdered Nembutal from China, and so on. Dissolve in water or fruit juice. Maybe eight or nine hundred bucks for a lethal dose. Some poor desperate soul takes the cash to MoneyGram and sends it off, and then waits at home, anxious and tormented, and never sees any powdered Nembutal from China, because there never was any. The powder in the on-line photograph was talc, and the prescription bottle was for something else entirely. Which I felt was a new low, in the end. They’re preying on the last hopes of suicidal people.
