...much as 50 times thinner than the earth's. It seemed almost certain that a relatively weak Martian gravity had allowed most of the planet's primitive atmosphere to leak off into space. There appeared to be practically no possibility that any of the lightest element, hydrogen, or its compounds, had remained long enough to play their essential role in the early evolution of life. Now it appears that such pessimism may have been unfounded. The newest studies of the Martian atmosphere indicate that it abounds in hydrogen compounds, some of which are similar to those produced...
...paper presented to an American Chemical Society meeting in San Francisco, Jet Propulsion Laboratory Astrophysicist Lewis Kaplan disclosed that spectrograms of the Martian atmosphere, made when the planet was 70 million miles from the earth last year, suggest that Mars has a concentration of hydrogen compounds in its atmosphere 1,000 times greater than the earth's. Those compounds probably include methane derivatives and possibly methane itself-a finding that could be significant because methane, or "marsh gas,"* is produced on earth by anaerobic bacteria, which do not require oxygen to exist. Even if the Martian methane...
...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...
