ABOUT RICHARD'S WORK
Richard Muller is a physicist and an inventor whose contributions are both experimental and theoretical.
His experimental work on cosmic radiation from the origin of the universe provided the first direct measurement of the velocity of the earth. He invented Accelerator Mass Spectrometry, the most sensitive method of detecting low levels of radioactivity and of dating samples for archaeology and geology. He and his group at Berkeley have built a system for the identification of astrophysical phenomena. As a result, they have discovered numerous supernovae. Based on an observed periodicity in mass extinctions of species on Earth, his work predicted the existence of a small star orbiting the sun, which he calls Nemesis. Muller is the author of several books including Nemesis (1988), The Three Big Bangs (1996), and Ice Ages and Astronomical Causes (2000).
BIOGRAPHY
Since 1978, Muller has been a professor of physics at the University of California, Berkeley and, since 1979, a senior scientist at the Lawrence Berkeley Laboratory, where he is associated with the Institute for Nuclear and Particle Astrophysics. His articles have appeared in such publications as Nature, Geophysical Research Letters, and Science.
Muller received an A.B. (1964) from Columbia University and a Ph.D. (1969) from the University of California, Berkeley.

关于理查德的工作
理查德-穆勒是一位物理学家和发明家,他的贡献包括实验和理论。
他对宇宙起源的宇宙辐射的实验工作提供了第一个对地球速度的直接测量。 他发明了加速器质谱法,这是检测低水平放射性和对考古学和地质学样本进行测年的最敏感方法。 他和他在伯克利的小组建立了一个用于识别天体物理现象的系统。 因此,他们已经发现了许多超新星。 根据观察到的地球上物种大规模灭绝的周期性,他的工作预测了一个围绕太阳运行的小星的存在,他称之为复仇女神。穆勒是几本书的作者,包括《复仇女神》(1988年)、《三次大爆炸》(1996年)和《冰期和天文学原因》(2000年)。
个人简历
自1978年以来,穆勒一直是加州大学伯克利分校的物理学教授,自1979年以来,他是劳伦斯伯克利实验室的高级科学家,在那里他与核和粒子天体物理学研究所有关。 他的文章出现在《自然》、《地球物理研究通讯》和《科学》等刊物上。
穆勒在哥伦比亚大学获得学士学位(1964年),在加州大学伯克利分校获得博士学位(1969年)。
