Copenhagen (18 page)

¹
Bernstein takes the trouble to explain in his book what few other commentators do—the difference between slow and fast neutrons: ‘By definition, slow neutrons move with speeds of the order of a few kilometers a second, about the speeds that molecules at room temperature move in a gas. That is why these neutrons are also referred to as thermal. Fast neutrons, the kind that are emitted in many nuclear processes, move at speeds of tens of thousands of kilometers a second.’
