PROF. PIERCE TO GIVE ILLUSTRATED LECTURE ON "RADIOTELEPHONY"
SPEAKER IS LEADING AUTHORITY ON ELECTRICAL OSCILLATIONS
A lecture on "Radiotelephony" will be given by Professor George W. Pierce '99, under the auspices of the Harvard Engineering Society, in the New Lecture Hall on Thursday evening, February 15, at 8 o'clock.
Professor Pierce holds the chair of Rumford Professor of Physics and is the Director of the Cruft High Tension and Radio Laboratory. He is recognized as a leading authority on electrical oscillations and electric waves, and has contributed much to the practical application of this field of science.
During the War he developed the apparatus used by the United States Navy for submarine detection, and invented the hydrophone, an instrument used for taking soundings in navigation. More recently he designed the wireless equipment of the Bowdoin, the ship in which MacMillan explored the Arctic Regions.
The lecture, which is open to members of the University and their friends, will appeal especially to those who have no intimate knowledge of the theory of radio. Professor Pierce will give a demonstration of reception, with loud speakers and amplifiers, and will explain the phenomena involved, calling particular attention to the influence of the vacuum tube on communication engineering.
