该提案支持美国国家科学院物理与天文学委员会（BPA）的会议和其他活动。委员会的作用是查明科学前沿的重要新发展，促进与其他领域的相互作用，加强与技术的联系，并促进科学界向国家提供有效的服务。BPA的成员来自大学、工业和联邦实验室。会议专门用于评价在其主持下开展的活动，讨论关键问题和制定新的倡议。一般来说，BPA发起的研究集中在物理和天文学的特定领域，由这些领域的特设专家组进行。这些小组编写的报告将对塑造该领域的未来方向产生相当大的影响。

This proposal supports meetings and other activities of the National Academy of Science's Board on Physics and Astronomy (BPA). The role of the Board is to identify important new developments at the scientific forefronts, foster interactions with other fields, strengthen connections to technology and facilitate effective service to the nation by the scientific community. Members of the BPA are drawn from universities, industry and federal laboratories. Meetings are devoted to evaluating activities being carried out under its auspices, discussing critical issues and developing new initiatives. In general, studies initiated by the BPA focusing on particular areas of physics and astronomy are carried out by ad hoc groups of experts in those areas. Reports produced by these groups will have considerale impact in shaping the future directions of the field.
