A Quote by Albrecht Kossel

The more the relationships of the nitrogen-rich substances to the cell nucleus were recognized, the more the question of the arrangement of the nitrogen and carbon atoms in the molecule came to stand out.

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.

Ernest Rutherford

Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life-the carbohydrates, amino acids, proteins, and lipids-is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

Michael Pollan

I started my scientific work by putting forward a hypothesis on the arrangement of atoms in nitrogen-containing molecules.

Alfred Werner

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.

Annie Dillard

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.

Primo Levi

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.

Peter Heller

In bitter almond oil, like in a great number of other substances that previously had been counted among the 'aromatic compounds' on behalf of their strong smell, a derivative of benzene is present. The special properties of benzene and its derivatives are caused by the typical arrangement of their carbon atoms.

Otto Wallach

Carbon's eastern neighbor on the table, nitrogen, dresses up diamonds in pinks, yellows, oranges, and brownish tints known romantically as 'champagne.'

Sam Kean

We have decisively changed the carbon cycle, the nitrogen cycle, and the rate of extinction.

Rob Nixon

I know Teddy Kennedy had fun at the Democratic convention when he said that I said that trees and vegetation caused 80 percent of the air pollution in this country. ... Well, now he was a little wrong about what I said. I didn't say 80 percent. I said 92 percent-93 percent, pardon me. And I didn't say air pollution, I said oxides of nitrogen. Growing and decaying vegetation in this land are responsible for 93 percent of the oxides of nitrogen. ... If we are totally successful and can eliminate all the manmade oxides of nitrogen, we'll still have 93 percent as much as we have in the air today.

Ronald Reagan

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.

Carl Sagan

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?

A single kind of red cell is supposed to have an enormous number of different substances on it, and in the same way there are substances in the serum to react with many different animal cells. In addition, the substances which match each kind of cell are different in each kind of serum. The number of hypothetical different substances postulated makes this conception so uneconomical that the question must be asked whether it is the only one possible. ... We ourselves hold that another, simpler, explanation is possible.

Karl Landsteiner

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.

Lawrence M. Krauss

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.
