与大师对话——诺贝尔奖获得者中国校园行
主讲人：物理学家，诺贝尔奖获得者罗伯特·威尔森教授
题目：微波背景和宇宙起源的探索
时间：2010年6月8日（星期二）下午2:30（2:15入场完毕）
地点：北京大学英杰交流中心阳光大厅
主办单位：北京大学物理学院天文系、北京大学国际合作部、校团委学术科创部
协办单位：北京大学青年天文学会
演讲者简介：
罗伯特·威尔森(Robert W. Wilson)教授毕业于美国Rice大学，1962年获得加州理工学院哲学博士学位。
Wilson教授早年就职于加州理工Owens Valley射电天文台，在提高射电天文学的测量精度和仪器灵敏度方面做出了卓越的贡献。
1964年，Wilson与同事Arno Penzias教授在调制高灵敏度的角形天线时，意外探测到了来自宇宙空间，各向同性的低温微波背景噪声。后得知这正是普林斯顿大学R.H.迪克所领导的研究小组应用大爆炸宇宙理论试图寻找的微波背景辐射。该发现为宇宙起源于大爆炸的理论假说提供了决定性的观测证据。Penzias与Wilson因为此项重大发现，同获1978年诺贝尔物理学奖。
1970年代，Wilson与其合作者进一步改进了射电望远镜的接收系统，使之能够探测到来自遥远天体的毫米波辐射，随即他们在猎户座星云中探测到了银河系第一个星际分子一氧化碳（CO）的转动量子跃迁。开创了毫米波天文观测的新时代，人类从此开始有效研究宇宙最冷暗区域的物理和化学性质。“CO分子发现40周年”国际研讨会将于6月6日-10在北大科维里研究所（KIAA）举行。
Wilson教授在1977-1994还担任贝尔实验室无线电研究部门首席科学家，在无线和光网络数据传输方面获得了多项专利。Wilson教授现在是美国科学院院士，史密森天文台的资深天体物理学家、国际天文学会会员。他还获得美国科学院Henry Draper奖章、英国皇家天文学会Herschel奖章。

Robert W. Wilson is a Senior Scientist at the Smithsonian Astrophysical
Observatory of the Harvard Smithsonian Center for Astrophysics in
Cambridge Massachusetts. He is technical leader of the Sub-Millimeter
Array, an 8 element synthesis radio telescope built by SAO in
conjunction with ASIAA near the summit of Mauna Kea, Hawaii.
From 1977 until 1994 Dr. Wilson was Head of the Wireless Technology
Research Department (formerly Radio Physics Research Dept.) of Bell
Laboratories in Holmdel, N.J. The Wireless Technology Research
Department did applied research on wireless access: components and
subsystems, new applications of simple inexpensive systems, and design
and architectures which support higher levels of integration. In its
former incarnation, the Radio Physics Research Department did research
on microwave and millimeter-wave semiconductor devices and components
as well as radio astronomy at those wavelengths.
Dr. Wilson received a B.A. "With Honors in Physics" from Rice
University in 1957 and a Ph.D. from the California Institute of
Technology in 1962. After a year at the Caltech Owens Valley Radio
Observatory as a postdoctoral fellow, he joined Bell Laboratories as a
member of technical staff.
His early work was in the fields of Galactic radio astronomy and
precision measurement of radio source strengths. He is best known for
his part in the discovery in 1964 of the 3~K cosmic black body
background radiation, thought to have originated in the early stages of
the expansion of the universe. In 1970 he and his co-workers extended
radio spectroscopy of the interstellar medium to short millimeter
wavelengths where they discovered a number of interstellar molecules
including Carbon Monoxide. His work in the resulting field of
molecular cloud astronomy has been concentrated on the structure of
nearby molecular clouds with interpretations based on observations of
several molecular species in each region. He has also applied
astronomical techniques to the measurement of earth-space propagation
for satellite communication at centimeter and infrared wavelengths and
made infrared propagation measurements along a terrestrial path. His
most recent work at Bell Labs was in wireless communications and
optical networking and resulted in a number of patents.
He is a co-recipient of the Henry Draper Medal from the U.S. National
Academy of Science and the Herschel Medal from the Royal Astronomical
Society, London and the 1978 Nobel Prize in Physics.
He is a member of the American Astronomical Society, the American
Academy of Arts and Sciences, the International Astronomical
Union, the International Union of Radio Science, the American
Physical Society, the National Academy of Sciences, The American
Philosophical Society, and was a member of the 1990 Astronomy and
Astrophysics Survey Committee (Bahcall Committee). |
