"No.—Won't you have a cigar?"

"No, I won't.—But the matter which is left still contains a vast quantity of unused atomic energy. If we used up the whole of the atomic energy, we should use up the whole of the atoms. In short, the matter would vanish altogether."

"Aha! Now I understand."

"It's just as though we were to grind corn badly—as if we ground up the thin outer husk and threw the rest away, just as we throw away ashes. When the grinding is perfect, there's nothing or next to nothing left of the grain, is there? In the same way, when there is perfect combustion, there's nothing or next to nothing left of the matter we burn. It's ground up completely. It is used up. It returns to its original nothingness. You know, it takes a tremendous amount of energy to make matter exist at all. Take away its existence, compel it not to be, and you thereby release an enormous supply of power. That's how it is, Bondy."
