But what sin is to the moralist and crime to the jurist so to the scientific man is ignorance.

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.

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

For a modern ruler the laws of conservation and transformation of energy, when the vivifing stream takes its source, the ways it wends its course in nature, and how, under wisdom and knowledge, it may be intertwined with human destiny, instead of careering headlong to the ocean, are a study at least as pregnant with consequences to life as any lesson taught by the long unscientific history of man.

It is probable that all heavy matter possesses - latent and bound up with the structure of the atom - a similar quantity of energy to that possessed by radium. If it could be tapped and controlled what an agent it would be in changing the world's destiny! The man who put his hand on the lever by which a parsimonious nature regulates so jealously the output of this store of energy would possess a weapon by which he could destroy the earth if he chose.

The dropping of the Atomic Bomb is a very deep problem... Instead of commemorating Hiroshima we should celebrate... man's triumph over the problem [of transmutation], and not its first misuse by politicians and military authorities.

The energy available for each individual man is his income, and the philosophy which can teach him to be content with penury should be capable of teaching him also the uses of wealth.
