Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.

The history of man is dominated by, and reflects, the amount of available energy

Man cannot influence in this respect the atomic forces of Nature.

There has been no discovery like it in the history of man. It puts into man's hands the key to using the fundamental energy of the universe.

Heat energy of uniform temperature [is] the ultimate fate of all energy. The power of sunlight and coal, electric power, water power, winds and tides do the work of the world, and in the end all unite to hasten the merry molecular dance.

On our plane knowledge and ignorance are the immemorial adversaries.

The fact remains that, if the supply of energy failed, modern civilization would come to an end as abruptly as does the music of an organ deprived of wind.
