Tracks of Time

  • Robert L. Fleischer


Picture yourself to be an atom in a crystal. Life would be monotonous and claustrophobic, with constant jostling by your neighbors, just enough to keep you as warm as they are. Occasionally, something really exciting would occur if you happen to be near a uranium atom that spontaneously fissions, so that you and many of your neighbors are given sudden short-distance rides like those of the atoms sketched in Figure l–8a. Between such events monotony takes over again.
