Rainer Kurt Sachs
Encyclopedia
Rainer Kurt Sachs is a German-American computational radiation biologist and astronomer. In particular he and Arthur Michael Wolfe
were the authors of the Sachs-Wolfe effect
, which concerns a property of the Cosmic microwave background radiation
.
. In 1937 the family left Germany to flee from Nazi persecution, and settled in the United States
, so Rainer Sachs is generally considered an American scientist. He received his bachelor's degree in mathematics from MIT
and his PhD in theoretical physics from Syracuse University
.
From 1969 to 1993 he was Professor of Math and Physics at the University of California, Berkeley
(UCB), and from 1993 he has been Professor Emeritus at UCB. In 1994 he was appointed Research Professor of Mathematics UCB, and since 2005 he has been an Adjunct Professor at the Tufts medical school.
Until 1985 he worked on general relativistic cosmology and astrophysics. He also co-wrote the books "General Relativity for Mathematicians" and "General Relativity and Cosmology". His contributions include joint work on the Sachs-Wolfe effect
and the Ehlers-Geren-Sachs theorem
, both of which deal with the Cosmic Microwave Background Radiation.
From 1985 he has worked in mathematical and computational biology, especially radiation biology. His work in radiobiology has included research on radiation and cancer.

Ehlers-Geren-Sachs theorem
The Ehlers-Geren-Sachs theorem, published in 1968 by Jürgen Ehlers, P. Geren and Rainer Sachs, shows that if, in a given universe, all freely falling observers measure the cosmic background radiation to have exactly the same properties in all directions , then that universe is an isotropic and...
