PHYSICISTS AND OPTICAL SOCIETY CONVENING HERE

A joint meeting of the American Physical Society and the Optical Society of America will mark the official openings of the new Research Building of the Jefferson Physical Laboratory at Harvard and the recently constructed spectroscopic laboratory at the Massachusetts Institute of Technology. The meeting will begin tomorrow and extend through Saturday, February 27. The first day's sessions take place at Technology, while meetings Friday and Saturday are at Harvard.

Sixty original papers on physical research which has been carried on by members of the society and twenty papers on optical subjects constituting "the main body of progress" in those sciences will be read during the course of the program it was announced by F. A. Saunders, professor of Physics at Harvard. While the bulk of the papers will be addressed to those familiar with the technical details of the subject matter, a number of symposiums on more general subjects will be given which will be of interest to many students and will be open to the public. A lecture on "Revealing the Universe through the Spectroscope" to be given tomorrow evening at Technology by H. N. Russell, of Princeton University is of this category.

University Speakers

Members of the University who will address the societies are J. C. Dunham, O. K. Rice, M. H. Johnson, Jr. '29, H. M. Smallwood, Professor E. L. Chaffee '11, William Duane '93, and Professor P. W. Bridgeman. Professor Chaffee will be chairman of the symposium on "Electronic Devices and their Applications to Research with Special Reference to Radiation Sensitive Devies", while Professor Bridgeman is to lecture on "Anomalies in the Behavior of Solids under Pressure", on Saturday at Pierce Hall. Both the latter sessions should be understandable by the average student.

Special arrangements are being made to clock the speakers in the Physical Society. Stop lights with a ten-minute interval are being installed.

The present meeting is the first to take place in Cambridge for over ten years. The University is entertaining the visiting societies and a lunch will be given Friday, February 26, at Leverett House. Members of the University who desire to obtain further information should apply at the secretary's office at the Jefferson Physical Laboratory.
