The nuclear age in which the human race is living, and may soon be dying, began for the general public with the dropping of an atom bomb on Hiroshima on 6 August 1945. But for nuclear scientists and for certain American authorities, it had been known for some time that such a weapon was possible. Work towards making it had been begun by the United States, Canada and Britain very soon after the beginning of the Second World War. The existence of possibly explosive forces in the nuclei of atoms had been known ever since the structure of atoms was discovered by Rutherford.
An atom consists of a tiny core called the "nucleus" with attendant electrons circling round it. The hydrogen atom, which is the simplest and lightest, has only one electron. Heavier atoms have more and more as they go up the scale. The first discovery that had to do with what goes on in nuclei was radioactivity, which is caud by particles being shot out of the nucleus. It was known that a great deal of energy is locked up in the nucleus, but, until just before the outbreak of the Second World War, there was no way of
releasing this energy in any large quantity. A revolutionary discovery was that, in certain circumstances, mass can be transformed into energy in accordance with Einstein's formula which states that the energy generated is equal to the mass lost multiplied by the square of the velocity of light.

It must have been around nine o'clock when I drove back home from work becau it was already dark. As I approached the gates I switched off the headlamps of the car so as to prevent the beam from swinging in through the window and waking Jack, who shared the hou with me. But I needn't have bothered. I noticed that his light was still on, so he was awake anyway -- unless he'd fallen asleep while reading. I put the car away and went up the steps. Then I opened the door quietly and went to Jack's room. He was in bed awake but he didn't even turn towards me.
