Quotes About Hydrogen

the supply of uranium in the planet is very limited, and it is feared that it may be used up before the human race is exterminated, but if the practically unlimited supply of hydrogen in the sea could be utilized there would be considerable reason to hope that homo sapiens might put an end to himself, to the great advantage of the other less ferocious animals.

Gaseous nitrogen combines with gaseous hydrogen in simple quantitative proportions to produce gaseous ammonia.

We are the representatives of the cosmos; we are an example of what hydrogen atoms can do, given 15 billion years of cosmic evolution.

The sun derives its energy from fusion reactions in which hydrogen is transformed into helium.

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.

For the universe to exist as it does requires that hydrogen be converted to helium in a precise but comparatively stately manner. Tweak the numbers even slightly and we would not be here. Optical

In the first lively second (a second that many cosmologists will devote careers to shaving into ever-finer wafers) is produced gravity and the other forces that govern physics. In less than a minute the universe is a million billion miles across and growing fast. There is a lot of heat now, ten billion degrees of it, enough to begin the nuclear reactions that create the lighter elements—principally hydrogen and helium, with a dash (about one atom in a hundred million) of lithium.

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.

dihydrogen oxide

All these different types of plastics have one thing in common: They contain carbon. Carbon, it turns out, is useful in creating all sorts of different materials because it bonds easily with a wide variety of different elements; in the case of plastics, it's usually clustered with hydrogen and oxygen.

Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say that there is more stupidity than hydrogen, and that is the basic building block of the universe.

There is more stupidity then hydrogen in the universe and it has a longer shelf life.

There is more stupidity than hydrogen in the universe, and it has a longer shelf life.

Most stars just fuse hydrogen into helium, but larger stars can fuse helium into other elements. Still larger stars, in turn, fuse those elements into slightly bigger ones, and so on.

First is Epsilon, which equals 0.007, which is the relative amount of hydrogen that converts to helium via fusion in the big bang.

El agua, a su vez, se puede descomponer en oxígeno e hidrógeno (que son los principales elementos del combustible para cohetes). Esto podría convertir la Luna en una gasolinera cósmica.

by the time the universe was a couple of minutes old, it was filled with a nearly uniform hot gas composed of roughly 75 percent hydrogen, 23 percent helium, and small amounts of deuterium and lithium. The essential point is that this gas filling the universe had extraordinarily low entropy. The big bang started the universe off in a state of low entropy, and that state appears to be the source of the order we currently see. In other words, the current order is a cosmological relic.

These are some of the things that hydrogen atoms do, given fifteen billion years of cosmic evolution.

This is the current state of our Sun, happily converting 600 million tonnes of hydrogen every second into helium to counteract the inward pull of gravity.

Some of the hydrogen in your body comes from the Big Bang, and when you see a kid walking down the street with a helium balloon, you can say, 'There goes some of the primordial universe.'

Water is the most neglected nutrient in your diet but one of the most vital.

The environmental benefits of hydrogen are also outstanding. When used as an energy source, hydrogen produces no emissions besides water. Zero polluting emissions, an amazing advance over the current sources of energy that we use.

They're trying to make fuel cells a reality. They want to bring the hydrogen economy to the United States.
