-
From the results so far obtained it is difficult to avoid the conclusion that the long-range atoms arising from collision of alpha particles with nitrogen are not nitrogen atoms but probably atoms of hydrogen, or atoms of mass 2. If this be the case, we must conclude that the nitrogen atom is disintegrated under the intense forces developed in a close collision with a swift alpha particle, and that the hydrogen atom which is liberated formed a constituent part of the nitrogen nucleus.

England and all civilised nations stand in deadly peril of not having enough to eat. As mouths multiply, food resources dwindle. Land is a limited quantity, and the land that will grow wheat is absolutely dependent on difficult and capricious natural phenomena... I hope to point a way out of the colossal dilemma. It is the chemist who must come to the rescue of the threatened communities. It is through the laboratory that starvation may ultimately be turned into plenty... The fixation of atmospheric nitrogen is one of the great discoveries, awaiting the genius of chemists.

The trade of chemist (fortified, in my case, by the experience of Auschwitz), teaches you to overcome, indeed to ignore, certain revulsions that are neither necessary or congenital: matter is matter, neither noble nor vile, infinitely transformable, and its proximate origin is of no importance whatsoever. Nitrogen is nitrogen, it passes miraculously from the air into plants, from these into animals, and from animals into us; when its function in our body is exhausted, we eliminate it, but it still remains nitrogen, aseptic, innocent.

Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.
→ -
Our bodies are garbage heaps: we collect experience, and from the decomposition of the thrown-out eggshells, spinach leaves, coffee grinds, and old steak bones out of our minds come nitrogen, heat, and very fertile soil. Out of this fertile soil bloom our poems and stories. But this does not come all at once. It takes time. Continue to turn over and over the organic details of your life until some of them fall through the garbage of discursive thoughts to the solid ground of black soil.

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.
→ -
For a Westerner to trash Western culture is like criticizing our nitrogen/oxygen atmosphere on the grounds that it sometimes gets windy, and besides, Jupiter's is much prettier. You may not realize its advantages until you're trying to breathe liquid methane.
→ -
....oysters are the only food that never causes indigestion. Indeed, a man would have to eat sixteen dozen of these acephalous molluscs in order to gain the 315 grammes of nitrogen he requires daily.
→ -
In a certain sense I made a living for five or six years out of that one star [υ Sagittarii] and it is still a fascinating, not understood, star. It's the first star in which you could clearly demonstrate an enormous difference in chemical composition from the sun. It had almost no hydrogen. It was made largely of helium, and had much too much nitrogen and neon. It's still a mystery in many ways ... But it was the first star ever analysed that had a different composition, and I started that area of spectroscopy in the late thirties.

Before the first atomic bomb test, scientists took the time to calculate whether the blast would ignite the nitrogen in Earth's atmosphere and incinerate us all. The risk was low and the test went off, but Rees wonders what the odds would have had to be to discourage the bomb makers.
→ -
We need to go back to our relationship with nature and understand that those trees are our lungs. The earth is recycling as our body. The rivers are our circulation. This air is our breath. And the star stuff, the carbon, hydrogen, nitrogen that comes from distant galaxies is actually the molecules of your body.
→ -
Each summer, for example, nitrogen and phosphate washing from farmlands in the Mississippi Valley enter the Gulf of Mexico, creating a massive algal bloom covering some 16,000 square kilometers. As the blooms die off, this area-roughly the size of New Jersey-is so deprived of oxygen that no fish survive.
→ -
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 sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive.
→ -
When we mistake what we can know for all there is to know, a healthy appreciation of one's ignorance in the face of a mystery like soil fertility gives way to the hubris that we can treat nature as a machine. Once that leap has been made, one input follows another, so that when the synthetic nitrogen fed to plants makes them more attractive to insects and vulnerable to disease, as we have discovered, the farmer turns to chemical pesticides to fix his broken machine.
→ -
I tell my students, with a feeling of pride that I hope they will share, that the carbon, nitrogen, and oxygen that make up ninety-nine per cent of our living substance were cooked in the deep interiors of earlier generations of dying stars. Gathered up from the ends of the universe, over billions of years, eventually they came to form, in part, the substance of our sun, its planets, and ourselves. Three billion years ago, life arose upon the earth. It is the only life in the solar system.
→ -
I believe that at the moment of death, that the soul is released in a molecular form, that actually goes into the - the fabric of the universe, the structure of hydrogen and nitrogen and oxygen because we're electrically - we're galvanic, we're electrochemical.

I've been experimenting more and more with LN2, liquid nitrogen. I've used it in battle on 'Iron Chef America,' but have also made some great ice creams at home for my family. Since it freezes basically on contact, you can have ice cream ready in mere minutes.

Four elements, Hydrogen, carbon, oxygen and nitrogen, also provide an example of the astonishing togetherness of our universe. They make up the "organic" molecules that constitute living organisms on a planet, and the nuclei of these same elements interact to generate the light of its star. Then the organisms on the planet come to depend wholly on that starlight, as they must if life is to persist. So it is that all life on the Earth runs on sunlight. [Referring to photosynthesis]

And to use something as elegant as a tree? Imagine this design assignment: Design something that makes oxygen, sequesters carbon, fixes nitrogen, distills water, makes complex sugars and foods, changes colors with the seasons, and self-replicates. and then why don't we knock that down and write on it?
→ -
Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen, and nitrogen struggle for billions of years to organize themselves into a professor of chemistry? What's the motive?
→ -
It's crazy, if you think about it. 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.

Science probes; it does not prove. Imagine Newton's reaction to an objector of his law of gravity who argued that he could not establish a universal law because he had not observed every falling apple, much less proved the law of gravity - there might, after all, be an apple that levitates! Why should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organize themselves into a professor of chemistry?

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.

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.

Nitrogen fertilizer is used on all crops produced in this country, but it is a key plant nutrient to produce corn a critical crop to Illinois farmers.
→ -
We have an atmosphere that is roughly 21% oxygen. The rest of it is largely nitrogen. There's just enough carbon dioxide (CO2) to drive photosynthesis. That has been, throughout the history of our species, pretty stable. Until recently.
→ -
Too often, chefs just want to experiment - they want to use liquid nitrogen before they know how to use heat.
→ -
We have decisively changed the carbon cycle, the nitrogen cycle, and the rate of extinction.
→ -
And how could I believe that Australian wine was automatically inferior to wine sourced from other regions on the planet when I had never drunk anything but liquid nitrogen?
