Tritium, an isotope of hydrogen that contains two neutrons and a proton in its nucleus, occurs naturally in minute quantities in raindrops and groundwater. But the radioactive gas took on strategic importance in 1952, when the U.S. exploded its first hydrogen bomb. That explosion demonstrated the destructive force that can be released when tritium fuses with deuterium, another hydrogen isotope, to yield helium and a burst of nuclear energy. Today, tritium is used both to enhance the power of atom bombs and in the trigger mechanism of the far more destructive H-bomb. Because it decays at the rate...

...cyclic changes in the sunspot population have, ever since Schwabe, inspired speculation about their effect on solar radiation and, consequently, on the earth. Though the sun is a rather ordinary star, its vital statistics are breathtaking by earthly standards. Some 865,000 miles in diameter, it consists largely of hydrogen (72%) and helium (27%) and is 333,000 times as massive as the earth. Solar temperatures range from about 27 million degrees F* in the core, where 600 million tons of hydrogen are fused into helium every second, to 10,000 degrees F on the photosphere, or surface...
