MINUTES OF THE 1993 FALL MEETING OF THE NEW ENGLAND SECTION OF
THE AMERICAN PHYSICAL SOCIETY
15-16 October 1993; Amherst, Massachusetts

GENERAL INFORMATION

The 1993 Fall Meeting of the New England Section of The American Physical Society was held on the campus of Amherst College in Amherst,Massachusetts.

The meeting was organized by Professor Kannan Jagannathan. There were 134 registrants of whom 67 were APS members, 10 emeriti, 6 non-members and 51 students. 124 attended the banquet Friday. There were 51 contributed papers, of which 38 are included in this APS Bulletin.

The theme of the Friday tutorial session was Precision Measurements. After welcoming remarks by Peter Pouncey, the President of Amherst College, Edward Hinds (Yale University) spoke on "Measurements of the Van Der Waals and Casimir-Polder Interactions," and Eric Adelberger (University of Washington) spoke on "Particle Physics at Ridiculously Low Mass Scales."

The theme of the Saturday tutorial session was Physical Phenomena in Restricted Dimensions. Moses Chan (Pennsylvania State University) spoke on "Phase Transitions of Two-Dimensional Systems," Robert Hallock (University of Massachusetts) spoke on "The Magic of ^3He on thin ^4He Films."

On Friday evening a social hour and banquet were held at the Lord Jeffrey Amherst Inn. Victor Weisskopf, Emeritus Professor of Physics at MIT, spoke on "Endangered Support of Basic Science."

The next meeting of the New England Section of The American Physical Society will be held as a joint meeting with the New England Section of the American Association of Physics Teachers, 9-10 April 1994 at Harvard University, Cambridge Massachusetts, under the direction of Howard Georgi, Department of Physics, Harvard University [telephone (617) 495-2866].
