各位老师和同学：
兹邀请Department of Physics, University of Washington的Paul Boynton教授、School of Physical Sciences, University of California Irvine的Riley D.Newman教授以及Eric Berg博士等人于7月13日至15日来我实验室访问，期间安排了系列报告（报告题目和时间如下），请请相互转告并准时参加。
13-Jul, PM：
Talk 1: 3:30 PM（TBD）Empirically testing a foundation of GTR（Prof . Paul. Boynton）
Talk 2: 4:30 PM， Review of G-2008 Analysis （Prof. Riley D.Newman）
14-Jul, 9:00 AM，
Talk1: Torsion Fibers at Low Temperature and Gravitational Inverse Square Law Tests （Prof. Riley D.Newman）
Talk2: Measurement of G Using a Cryogenic Torsion Pendulum, The Story up to 2008 （Dr. Eric Berg）
CV of talkers:
Professor Emeritus, Physics & Astronomy
School of Physical Sciences, University of California Irvine
Research Interests：Experimental elementary particle and gravitational physics
Current works are focusing on precision gravity tests with cryogenic torsion balances:
1. Measurement of the gravitational constant G, (motivated by large discrepancies between results of G measurements by other groups in recent years),
2. Searches for new extremely weak forces in nature with macroscopic range,
3. Tests of the equivalence of inertial and gravitational mass.
