Uranium is a tricky element. As it comes from the mines, it contains only .7% of the active isotope U-235, whose atoms "fission" (split in two) with a big release of energy. Nearly all the rest is 11-238, an idle isotope which will not fission naturally, though its heavy nucleus contains about the same energy...
...chain-reacting pile, its U-235 atoms start splitting and yielding energy, "fission products" and free neutrons. Some of the neutrons are needed to split more U-235 atoms and keep the reaction going. Others are absorbed by impurities or escape from the pile. The rest enter the atoms of U-238, ultimately turn them into plutonium...
...very frenzied fashion. They read rapidly, desperately and far too much. And because they tended to believe that all facts (and only facts) were important, and, what is more, equally important, the result was often a fearful intellectual congestion from which many of them will probably suffer for the rest of their lives...

Wild life and religion stand out as about the only two comprehensible characteristics of Charles Waterton. Investigating the rest of him is like entering a maze that turns out to have been planned as a staggering hoax. Many (including Novelist Norman Douglas and Poet Edith Sitwell) have been lured down the winding trails that appear to lead to the Watertonian heart of the matter-only to find that a conglomeration of blind alleys is, itself, the mysterious center of the weird and wonderful meanderer. Biographer Richard (The Duke) Aldington, in the most complete work on Waterton to date, explores...
