...sodium and sulphur electrodes in liquid form, a temperature the company believes can be maintained by effective insulation of battery cells and by frequent charging. Care must also be taken that the battery's sodium does not come into contact with water; the combination produces highly inflammable hydrogen...
...semester. They successfully demonstrated it for the first time this June. Subsequent experiments uncovered a few problems, though none seem impossible of solving in the construction of a full-scale sub. Electric current passing through the water between the electrodes produces some electrolysis; molecules of water break down into hydrogen and oxygen, which rises to the surface in the form of gas bubbles that could signal the sub's presence below. Swimmers who guided the sub felt a tingling but harmless sensation caused by the electric current. "It is almost exhilarating," explains...
...whatever he achieves,' can measure up to the white Superman.'' The adult, too, is everywhere assaulted by ideas that take violence for granted, that brutalize and desensitize Americans to the value of individual life. In this sense, writes Wertham, "we are the victims of the hydrogen bomb before it is ever used," because its very existence forces society to contemplate genocide. Tobacco and alcohol advertising, he believes, also teach a subtle disregard for human welfare, as does the U.S. acceptance of the annual total of traffic fatalities-"vehicular violence." Even patriotism comes under Wertham's rebuke...
...school argues that an IL-28 could easily deliver the latest nuclear test devices, while a second school believes that the Chinese are working to bypass the bomber stage and are pouring their energies into producing rocket-deliverable hydrogen warheads. Though U.S. Defense Secretary Robert McNamara maintains that the Chinese will not have a functioning ICBM until 1975, many Hong Kong China-watchers believe that Peking will have full-fledged ICBM thermonuclear capability by 1970 or 1971. "They're never going to be able to challenge the U.S. or the Soviets in a nuclear shoot-out," says...
...delicate an instrument is the human ear that at certain frequencies it can discern sound that moves the eardrum a distance only one-tenth the size of a hydrogen atom. The close-up roar of a jet engine amounts to one million billion times this threshhold level; this causes actual pain and soon brings on permanent deafness. Sound vibrations are transmitted by the eardrum and ossicle bones to the inner ear, a bony and membranous structure lined with tiny hairs that connect to the brain's auditory nerve. It is these hairs that are damaged most in noise-induced...
