More Matter. The physicists are creeping up on the origin of matter. Dr. Robert Andrew Millikan of the California Institute of Technology, pursuing his study of the cosmic ray, has illuminated new chapters in the celestial life of the hydrogen atom. Those infinitely tiny but infinitely active particles not only leap at each other explosively to form helium, but also by special jumps unite to form oxygen and nitrogen. The exact nature of the jump is not yet fully understood, but each different jump shoots off its own private signal, a ray of definite power...
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...
Professor R. A. Millikan, Director of the Norman Bridge Laboratory of Physics of the California Institute of Technology, will give a series of six free public lectures on twentieth century discoveries in physics at the Lowell Institute early in April...
...Physicist Millikan directly observed the absorption coefficient of the most conspicuous band in the cosmic ray spectrum. It was within a few per cent .305. Things equal to the same thing being equal to each other, it seems that positive and negative electrons are daily uniting in the heavens to form helium and sending us a free cosmic ray as an announcement...
...Millikan cautions against rash constructions. The experiments are not yet completed and 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...
