Zitat des Tages über Wasserstoff / Hydrogen:
Had we not pursued the hydrogen bomb, there is a very real threat that we would now all be speaking Russian. I have no regrets.
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.
We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.
A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which it may be made to move.
I was having a conversation with my father and he was talking about this thing - strangeness and charm. It's actually the name of the two smallest particles that there are when you split the atom, so I wrote a song around it. I even managed to fit the word 'hydrogen' in there. Isn't that a nice thing for scientists to call them though?
The president's decision yesterday to set into motion the development of the hydrogen bomb... has placed us on the knife-edge of history.
Naturally, I was a bit of a curiosity, being the first hydrogen peroxide ingestion patient they had ever seen.
The whole of the hydrogen on the earth might be transformed at once and the success of the experiment published at large to the universe as a new star.
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.
Investigations during the last few decades have brought hydrogen instead of carbon, and instead of CO2 water, the mother of all life, into the foreground.
Detroit is saying that the hydrogen vehicle is the vehicle of the future. But it's 15 years from now.
As we explore ways to bring price relief and bolster our country's energy independence, one significant energy source has emerged as a potential solution, hydrogen fuel cells.
If we were driving pure hydrogen automobiles, that automobile would actually help clean up the air because the air coming out of the exhaust would be cleaner than the air going into the engine intake.
Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organise themselves into a professor of chemistry? What's the motive?
For example, a breakthrough in better batteries could supplant hydrogen. Better solar cells could replace or win out in this race to the fuel of the future. Those, I see, as the three big competitors: hydrogen, solar cells and then better batteries.
Only in the last week, South Carolina announced that it is seeking to become the U. S. center for hydrogen fuel cells, and BMW revealed that it will power some of its high-end model cars with hydrogen.
The two most common elements in the universe are hydrogen and stupidity.
If the human condition were the periodic table, maybe love would be hydrogen at No. 1. Death would be helium at No. 2. Power, I reckon, would be where oxygen is.
On the morning of January 17, 1966, a real-life dirty bomb crisis occurred over Palomares, Spain. A Strategic Air Command bomber flying with four armed hydrogen Bombs - with yields between 70 kilotons and 1.45 megatons - collided midair with a refueling tanker over the Spanish countryside.
We frequently define an acid or a base as a substance whose aqueous solution gives, respectively, a higher concentration of hydrogen ion or of hydroxide ion than that furnished by pure water. This is a very one sided definition.
Hydrogen holds great promise to meet many of our future energy needs, and it addresses national security and our environmental concerns. Hydrogen is the simplest, most abundant element in the universe.
Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe.
And when these advances are made, hydrogen can fill critical energy needs beyond transportation. Hydrogen can also be used to heat and generate electricity for our homes. The future possibilities of this energy source are enormous.
Agriculture is now a motorized food industry, the same thing in its essence as the production of corpses in the gas chambers and the extermination camps, the same thing as blockades and the reduction of countries to famine, the same thing as the manufacture of hydrogen bombs.
This oxidation of hydrogen in stages seems to be one of the basic principles of biological oxidation.
At first, I was able to use a Bunsen burner attached to my mother's gas stove, but the use of the kitchen as a laboratory came to an abrupt end when a minor explosion involving hydrogen sulphide spattered the newly painted decor and changed the colour from blue to dirty green!
There is more stupidity than hydrogen in the universe, and it has a longer shelf life.
So I submit to my colleagues here today that hydrogen is not as far away as we think it is.
Fuel cell vehicles run on clean-burning hydrogen and are three times more efficient than the traditional combustible engine.
The foodstuff, carbohydrate, is essentially a packet of hydrogen, a hydrogen supplier, a hydrogen donor, and the main event during its combustion is the splitting off of hydrogen.
It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.
We must move away from our dependency on fossil fuels, and I am glad that GM has invested over $1 billion in hydrogen fuel cells cars to meet this goal.
The universe starts off with the Big Bang theory, and the first thing that emerged from the Big Bang is essentially hydrogen and then helium. And that's what combusts in stars. Finally, stars implode, and they build heavier elements out of that. And those heavier elements are reconstituted in the heart of other stars, eventually.
Since hydrogen is a constituent of most of our electrolytic solvents, the definition of an acid or base as a substance which gives up or takes up hydrogen ion would be more general than the one we used before, but it would not be universal.
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.
The strands of the DNA double helix are held together by hydrogen bonding interactions between the complementary base pairs. Heating DNA in solution easily breaks these hydrogen bonds, allowing the two strands to separate - a process called denaturation or melting.
