...somewhat closer to reality than most people realize. In laboratories in the U.S., the Soviet Union, Western Europe and Japan, scientists are involved in a spirited competition to become the first to achieve one of the most important-and difficult-goals ever sought by man: the harnessing of nuclear fusion. If that goal is reached, the world may never again be faced with an energy crisis...
Invisible Springs. Compared with the difficulties of controlling fusion, producing energy from nuclear fission is relatively simple. In fission-which occurs in A-bomb explosions and powers today's nuclear plants-a speeding neutron is used to split the atomic nucleus of a heavy element like uranium into the nuclei of one or more lighter elements. In the process, more neutrons are given off. But the mass of the resulting nuclei and neutrons is somewhat less than the mass of the original nucleus; the missing matter-as predicted by the famed Einstein equation E=mc2-has been converted into...
...nuclear fusion-the process that feeds the fires of the sun and gives the H-bomb its awesome power-atomic nuclei of light elements like hydrogen collide and merge. The resulting nuclear particles contain less mass than the sum of the original nuclei; again, matter has been converted into energy. But while atomic nuclei easily split, they do not easily fuse; they have positive electric charges and thus repel each other, acting as if they had invisible springs between them. Getting them to join requires that they approach each other with enough energy to overcome their natural repulsion and smash...
...more energy"-or taxed, with revenue returning to the consumer. 2) The Republican program pushes nuclear power more than the Carter plan. It calls for research into the reprocessing of spent nuclear fuel, continued development of the fast breeder reactor (all but buried by Carter) and stepped-up fusion research, which Carter would trim. It comes out strongly for developing geothermal energy, which the Government's own scientists regard as only marginally promising...
...primitiveness; or Ingres's Study for Andromeda, a fascinating closeup of a lone marble woman that lets you see how Ingres sculpted his figures to achieve that smooth sensuality of form; or Monet's Fish (1870) whose glinting gold and silver scales formed of his brushstrokes, are the perfect fusion of technique and subject; or Sargent's Breakfast...
