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. Martin Heidegger
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. Bill Bryson
For the foreseeable future, we're going to need oil products because I don't like the idea of hydrogen cars. I'm not sure I want to be cruising around a mall parking lot filled with a thousand mini-Hindenburgs. Dennis Miller
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. Dan Lipinski
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. Francis William Aston
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. Gilbert N. Lewis
