...been treated with results described as "very satisfactory." The method of treatment revolves around the use of a system of insulation which prevents the beta rays of radium and X-rays that are caustic to all tissue from reaching the area to be treated. It is believed that the gamma rays are the efficient agents in the treating of cancer by radium. By cutting off the beta rays by insulation, a greater concentration of gamma rays than hitherto could be safely used, may be applied without harmful or painful effect. The treatment consists of irradiation applied externally. After a time...
...famed little New England College. He will never play on an important varsity team. But he sings first bass in the glee club and may eventually become its leader, although this post usually goes to a tenor. He has been initiated into his father's fraternity (Phi Gamma Delta). He has met with decorum all the customary American assaults upon the dignity of a freshman (they once made him speak half an hour from a soapbox in praise of Senator LaFollette). And President George D. Olds-veteran professor who succeeded Alexander Meiklejohn - described his academic record as being "very...
...deep red, with waves 28 millionths of an inch long. On the "ultra" side of this spectrum, occur the ultraviolet rays with waves 1 millionth of an inch; then a range of little-known shorter vibrations; then the famed X-rays; then, shortest of all known rays, the gamma rays given off by radium. On the infra or long wave side of visible light come infrared, then longer heat waves (16 mil- lionths to 12 thousandths of an inch), then Hertzian or radio waves, measuring from a few metres to several miles in length. The longest waves in the spectrum...
...What it is made up of is still a mystery to the world and it is hoped that Professor Shapley's observations may shed some light on the subject. His lecture, which is open to the public, is given under the auspices of the Harvard chapter of the Gamma Alpha Scientific Society...
