...other labs, Professor Kenneth T. Bainbridge is studying the mass spectrograph, and Professor Edward M. Purcell is working on nuclear-magnetic moments, which isn't half as simple as it sounds...
Working with short, amiable spectrograph expert Milton Humason, Hubble studied the light of the distant nebulae. In every case he found a "red shift."* The farther off a nebula was, the faster it appeared to be rushing away, and the enormous speeds (thousands of miles per second) were new, strange and startling to astronomers...
...years. Last month, McDonald Observatory at Fort Davis, Tex., had a wonderfully "steady" night. Struve trained the 82-inch reflecting telescope on the Companion of Antares. The image of the Companion trembled hardly at all. In a few rare minutes, he was able to coax it separately into a spectrograph and photograph its spectrum under almost ideal conditions without interference from the brilliant red light of nearby Antares...
Died. Dr. Francis William Aston, 68, British chemist who won a 1922 Nobel Prize for inventing the mass spectrograph, through which heavy water and uranium 235 (atomic bomb ingredient) were discovered; in Cambridge, England. He once warned against atomic tinkering: "All hydrogen on earth might be transformed at once, and this most successful experiment published to the universe [as] a new star of extraordinary brilliance...
