...shock of a helium nucleus crashing into the nucleus of a nitrogen atom causes an explosion which disintegrates the atom. Out of the wreck a new fluorine atom emerges, but not for long. It explodes immediately, shooting off a furiously fast atom of hydrogen and a slower atom of a new kind of oxygen which is heavier than either the helium or the nitrogen atom. According to Einstein's theory, when helium is formed from lighter hydrogen atoms, energy is given off (enough to heat an ordinary house from 500 to 1 ,000 years in the formation...

This was the energy that Millikan demonstrated in the cosmic ray (TIME, March 26). But the helium-nitrogen activity seems to be just the opposite. When helium and nitrogen collide and explode, forming oxygen and hydrogen, energy appears to be stored rather than given off. From this have arisen arguments which support the theory of Prof. Thomas Chrowder Chamberlin-that the earth has been built up by the aggregation of smaller bodies such as meteorites or planetesimals, in which energy has been stored...

...turned to Einstein's theories. He found, using the Einstein equation (M C 2-E), that the most conspicuous band in the cosmic ray spectrum is probably the same band that would be formed by the monochromatic ether wave of the radiant energy which is liberated when hydrogen unites to form an atom of helium. Einstein's figure was reached by calculation: he reasoned that if 4 atoms of hydrogen united to form helium, a definite amount of matter would go off in the form of radiant energy. This energy, appearing in the form of a monochromatic ether...

...much remains to be proved, but he admits these discoveries to be the first indications that elements are being continually created from electrons. Support for this hypothesis can be found on all sides. On the side of the sun, for instance, there is an extraordinary abundance of both hydrogen and helium. What is more plausible than that the one should be created from the other? On the side of physics, there are no other nuclear changes which could take place, as far as science knows now, that would be powerful enough to produce the cosmic ray discovered by Dr. Millikan...

...Senftner went out into the cow-yard and found the dairy-man's herd of 13 cows all sick, their udders and teats pocked with pustules. The diagnosis was: cowpox, long a rare disease among animals, as well as among humans. The treatment: applications of mercurochrome and hydrogen peroxide to the sores and wet dressings of aluminum acetate...
