...times the weight of air at sea level. Cosmic rays ionize the imprisoned nitrogen. If the telescope is pointed at a source of the rays the gas in one sphere should be ionized less than the gas in the other. If the cylinder is swung athwart the ray, ionization should be equal in both spheres. Dr. Swann plans to swing his "telescope" to and fro until he can judge whether atoms are dying in the stars (Jeans) or are aborning between the stars (Millikan...
