CAL TECH WAS FORTUNATE TO MAKE THE ACQUAINT- ANCE OF PROFESSOR STEINER OF GRINNELL COLLEGE THIS YEAR. PROFESSOR STEINER is a noted edu- cator, philosopher, author, and lec- turer. His work has consisted mainly in teaching and in writing. He has written many books concerning the immigration problem in the United States. PROFESSOR STEINER came to our campus this year due to the efforts of CHUCK SCHWIESO and DR. SOARES, who thought the contact afforded the men would prove valu- able. While here he gave two inter- esting assembly talks, two Atheneum lectures, and several Sunday break- '3 'x i? 93 fast club talks. He also visited several colleges nearby and gave talks to their students. DR. BEARD'S visit to the campus was more brief than usual, but was nevertheless valuable to the associates of the Institute. DR. BEARD is a noted authority on government and has written many books on the subject. His most recent work is iiThe Rise of American Civilization, which was written in co-operation with his wife. DR. BEARD while here gave four very interesting Atheneum lectures on the general subject of What Is National Interest? ' Another visitor to the campus this year who received considerable atten- tion was SENATOR GUGLIEMO MAR- CONI, who, with his wife, visited the campus for one day during his first trip to Southern California. 21 VISITING PROFESSORS P1r'0fe5501' Steiner Marconi and his wife

RESEARCH WORK CARRIED ON DURIN G THE YEAR HAS MADE SCIENTIFIC HISTORY. PHYSICS RESEARCH in physics has been in six fields and four specialized problems. Financed by the cosmic ray fund, a great deal of research has been done recently on these interesting radia- tions and kindred phenomena. The most recent results were ob- tained during the Settle balloon ascension and during a two and one- half monthsi voyage Which led inves- tigators to South America. Additional data have been obtained through sev- eral high altitude airplane flights in the mountains of South America. This interesting and important re- search has been under the direction of DOCTORS ROBERT A. MILLIKAN, IRA S. BOWEN, CARL D. ANDERSON, and HENRY V. NEHER, aided by DR. FRITZ ZWICKY 0n the theoretical aspects. LOW TEMPERATURES MUCH experimental work has been done by DR. ALEXANDER GOETZ in the investigation of properties of met- als and crystals at extremely low tem- peratures. In the cryogenic labora- tory liquid helium has been obtained and temperatures as low as two de- grees absolute produced. Using this. extensive liquefying equipment, in- vestigation has been started on metal crystals and super-conductivity at low temperatures. X-RAY DR. JESSE DUMOND has been in charge of a group of x-ray problems being investigated. His work during the past year has been largely that of designing a new thirty-kilowatt x-ray tube which will be used for pure re- search only. The two most impor- tant features which distinguish this tube are the intensity of x-rays pro- duced and the revolving 0f the target or anode. The purpose of the tube is to provide a large quantity of rays in order to determine certain proper- ties of matter which are too faint for measurement in the rays of weaker tubes. y SPECTROSCOPIC PROBLEMS A NUMBER of effects have been studied recently by spectroscopic means. DR. IRA S. BOWEN has been studying the x-rays of longer wave lengths. DR. WILLIAM R. SMYTHE has used the mass spectograph in the separation of the isotoPes of several elements, particular work being done on the separation of the radio active isotope of potassium. 23 RESEARCH Dm.
