Quotes About Hydrogen

We presently have the technology ... fuel cells, solar cells, hydrogen ... the opportunities are amazing for clean energy.

Hydrogen is a light, odorless gas, which, given enough time, turns into people.

Would the hydrogen catch fire? Alek grasped the edge of the window, hardly feeling the broken glass against his palms. "Deryn" he sobbed. Anything but this.

Methylation works by the use of a chemical compound, in the shape of three-leaf clovers made up of hydrogen and carbon

The wood of any tree growing anywhere records fairly faithfully the oxygen and hydrogen chemistry of the water the plant has access to through precipitation.

This hydrogen was under such enormous pressure that it had become a metal.

The fine-structure constant derives its name from its origin. It first appeared in Sommerfeld's work to explain the fine details of the hydrogen spectrum. ... Since Sommerfeld expressed the energy states of the hydrogen atom in terms of the constant [alpha], it came to be called the fine-structure constant.

American scientists blew up a hydrogen bomb that was a hundred times as powerful as the one used in Hiroshima right outside the atmosphere in the summer of 1962, just to find out what would happen.

all perception is but a change in the concentration of hydrogen ions on the surface of the brain cells.

Eventually, however, the star will run out of its hydrogen and other nuclear fuels. Paradoxically, the more fuel a star starts off with, the sooner it runs out. This is because the more massive the star is, the hotter it needs to be to balance its gravitational attraction.

Close analysis of starlight revealed that stars are made of the same kinds of atoms as we find here on Earth, with Cecilia Payne-Gaposchkin eventually proving that they are mostly hydrogen and helium.

If the strong nuclear force were slightly weaker, multi-proton nuclei would not hold together. Hydrogen would be the only element in the universe.

he was doing a breath hydrogen test. If you know the amount of hydrogen someone is exhaling orally, it's a simple matter to extrapolate the amount they're exhaling rectally. This is because a fixed percentage of hydrogen produced in the colon is absorbed into the blood and, and when it reaches the lungs, exhaled. The breath hydrogen test has given flatus researchers a simple, consistent measure of gas production that does not require the subject to fart into a balloon.

Hydrogen sulfide is as lethal, molecule for molecule, as cyanide. This may explain why humans evolved such exquisite sensitivity to its smell.

Hydrogen sulfide is so swiftly lethal that farm- and workplace-safety organizations urge anyone who enters a manure pit or attempts to clear a blocked sewage pipe to wear a self-contained breathing apparatus.

Morning breath" is hydrogen sulfide released by bacteria consuming shed tongue cells while you mouth-breathe for eight hours; saliva normally washes the debris away.

Yet none of these models actually is hydrogen!

I don't believe that a hydrogen economy depends on a carbon economy at all.

Dans le brasier initial l'hydrogène se transforme en hélium, l'atome à peine plus complexe que lui. Mais déjà, de cette transformation on peut déduire la première grande règle du jeu de notre univers : TOUJOURS PLUS COMPLEXE.

In France, a chemist named Pilatre de Rozier tested the flammability of hydrogen by gulping a mouthful and blowing across an open flame, proving at a stroke that hydrogen is indeed explosively combustible and that eyebrows are not necessarily a permanent feature of one's face.

Not all chemicals are bad. Without chemicals such as hydrogen and oxygen, for example, there would be no way to make water, a vital ingredient in beer.

How wonderful to find in living creatures the same substance as those which make up minerals. Nevertheless they felt a sort of humiliation at the idea that their persons contained phosphorous like matches, albumen like white of egg, hydrogen gas like street lamps.

Travel requires a great deal of energy - whether you go by car, by bus, by train or plane. We'll likely be using hydrogen as our main energy for transport.

A drop of water is not immortal; it can be resolved into oxygen and hydrogen. If, therefore, a drop of water were to maintain that it had a quality of aqueousness which would survive its dissolution we should be inclined to be skeptical. In like manner we know that the brain is not immortal...
