Putting salt on the tail of a cosmic corpuscle which can penetrate 10 centimeters of lead is no mean feat, but Jabez C. Street, assistant professor of Physics, and Edward C. Stevenson, instructor in Physics, have succeeded in doing just that, according to announcements from Jefferson Research Laboratory...
...machine used to trap this elusive iota is known as a cloud chamber. Nothing new, this apparatus has been in use since 1910; it consists of a chamber containing a mixture of liquid and gas and several lead plates, through which the cosmic radiations pass--the gas is cooled, and produces a fog track along the path of ions formed by the charged corpuscles. This track of condensed vapor can be easily seen with the naked eye and also photographed, showing up as a bright streak on the film. Thus electrons, protons and the new particles, although far too infinitesimal...
...like the accepted manner of an electron, which characteristically forms high energy photons, which in turn form more electrons to produce the phenomena known as "electron showers." Due to these showers electrons soon lose their energy, and consequently haven't enough "push" to make much progress through lead. These newly-discovered specks, however, pass through ten centimeters of the metal almost undeviated, with little appreciable loss of energy, and producing no showers...
...game in which the lead changed hands three times, the Crimson batters pounded a trio of enemy twirlers for 11 hits. Captain Tom Bilodeau, who crossed the plate with the tying run in the eight, led the Varsity at bat with a single and a triple...
Even with Johnson performing as expected, however, Columbia could not have retained its title of supremacy for the Eli's with a well balanced team piled up a lead of nearly twenty points over the favorites...
