Here's a bit more detail, in pulp classic style:
By the time Gallun wrote this in 1937, research into cosmic rays (the largest single constituent of which are protons) was just starting. By the turn of the century, physicists were puzzled by radiation in the environment, which seemed to be higher than would be expected from terrestrial sources.
To settle the debate, a daring German scientist, Victor Hess, ascended to more than 17,000 feet in a balloon (without oxygen!) in 1912. His gold leaf electroscope showed that the higher he got, the more the radiation level increased. Scientists became convinced that the radiation did indeed come from outer space and coined the phrase "cosmic radiation" to describe it.
By 1929, Russian physicist Dmitry Skobelzyn observed cosmic ray tracks in the newly invented cloud chambers. Further research demonstrated that cosmic "rays" were primarily composed of particles. Subatomic particles were finally seen in 1937, giving birth to the field of particle physics. Particle physicists used cosmic rays for their research until particle accelerators were developed in the 1950's. Comment/Join this discussion ( 3 ) | RSS/XML | Blog This | Additional
