...decade had a chaotic vitality and charm. His title implies a Watergate history, but the book is something quite different-an odd and lovely exercise that is part autobiographical meditation, part elegiac crank letter to the American Republic, part confession and part essay on democratic politics. "I still fuse my public and private worlds," Mee writes. "All visions of the world are autobiographies...
...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 together. Thus causing large numbers of nuclei to fuse and provide substantial...
...first steps on that ascent was the realization that the conditions of temperature and density necessary for the sustained fusion of ordinary hydrogen nuclei were far beyond the present capabilities of science. But experiments showed that it was easier to fuse two isotopes, or different forms, of hydrogen: deuterium and tritium. Reason: the nuclei of these isotopes have larger cross sections than those of ordinary hydrogen nuclei. Thus the probability of direct collisions between them is increased and that in turn means that less extreme conditions are required to make them fuse. The easiest fusion to attain, scientists determined...
...causes instant vaporization, or boiling away, of the outer surface of the sphere. As the pellet coating flies outward, it pushes back against the deuterium and tritium, compressing and heating the mixture. If the impinging beams are energetic enough, the effect will be so great that the nuclei will fuse, releasing energy like a miniature H-bomb. Among others, researchers at Los Alamos (N. Mex.) Scientific Laboratory and the Lawrence Livermore lab have achieved fusion in laser experiments with the pellets. More impressive reactions may occur in late 1977, when scientists at Lawrence Livermore complete work on the $25 million...
