...fastest-changing component, says Dr. Aebersold, is water. It forms about 70% of the body, and about half the water molecules are replaced every eight days. Other fleeting elements are carbon, sodium and potassium. The calcium and phosphorus in bones and teeth stay put longer, but even they are not permanent. "Bones are quite dynamic." says Dr. Aebersold. The little crystals in bones are continually dissolving and reforming. In the process, some of the atoms are lost...
...shock wave, they were almost noiseless, and each was equipped to fire three kinds of bullets: small lead pellets for merely stunning victims, nickeled-steel bullets that proved capable of penetrating 2¼ in. of pine board at 24 ft., and dum-dum slugs smeared with a mixture of potassium cyanide...
...high temperature (which favors efficiency) without high pressure, another reactor will have heat-resistant graphite as its moderator and will be cooled by a molten sodium-potassium alloy. Still another will have a novel gimmick. Its cooling water will be allowed to boil, and the steam generated will be used directly to drive a 5,000-kw. turbine. This cuts out the conventional heat exchanger used in the reactor of the submarine Nautilus to generate nonradioactive steam. Dr. Smyth did not say so, but the turbine will probably become so radioactive that it cannot be approached by humans...
...Britain's B.E.A.M.A. (British Electrical and Allied Manufacturers' Association) Journal, Engineer F. T. Bacon of Cambridge describes the most hopeful approach so far to a practical fuel cell. Bacon uses two diaphragms of porous nickel set close together with an electrolyte (a solution of potassium hydroxide) between them. Hydrogen gas at the pressure of 800 Ibs. per sq. in. seeps through one diaphragm, oxygen through the other. They combine in the electrolyte, and the energy of their "burning" appears as electricity, not as heat...
After careful discussion of the matter with Roommate Wepman, a Miami attorney's son with vague literary pretensions, Chemist Fraden decided to use potassium cyanide as a terminal agent. One evening last August, he put a vial of the stuff in his pocket, got a bottle of champagne, called on his parents and joyously announced that he had got a job. He poured three glasses of wine, added cyanide to two of them, and asked his parents to join him in a toast to his future. They drank and toppled to the floor...
