Biography

Early life and education

Sachs was born in Portland, Oregon, the third son of a rabbi. When just four months old, Sachs moved with his family to Toronto, Canada, where he grew up and attended school.[2]

honorable discharge from the Navy in August 1946.[4]

Sachs earned his bachelors at the

Charles Townes and Hideki Yukawa) While at Columbia Sachs was taught by Willis Lamb and Hideki Yukawa.[5] Yukawa had agreed to be Sach's thesis advisor, but Sachs decided to complete his doctorate back at UCLA so that he could be reunited with Yetty Herman, whom he married in 1952.[6]

Career

Following the award of his PhD in 1954 Sachs first post-doctoral position was at the new

field theory. Unfortunately Einstein died in April 1955 and Sachs never had the opportunity to talk to him about his ideas.[7]

In 1956 Sachs became a senior scientist at

San Jose State College. In 1961 he became a research professor at McGill University; this was followed by a post as associate professor of physics at Boston University
(1962–1966).

In 1964 while at

Cambridge University. While working with Dirac, Sachs also had the opportunity to discuss ideas with John G. Taylor, John Polkinghorne and graduate students at DAMTP.[9]

.

In the autumn of 1966 he was appointed professor of physics at State University of New York at Buffalo.

Sachs was an editor for the International Journal of Theoretical Physics.[11]

On his retirement in 1997 he was given the title Professor of Physics Emeritus.

Willis E. Lamb and Herbert A. Hauptman and a subsequent festschrift was published.[12] Sachs published 13 books and over 200 journal articles during his life.[13]

Research

Unified field theory

Sachs progressed towards completing Albert Einstein's unified field theory, i.e. unifying the fields in general relativity, from which quantum mechanics emerges under certain conditions.

His theory rests on three axioms. The general idea is (1) to make precise the

Mach principle, positing that all manifestations of matter, not only inertial mass, derive from the interaction of matter. From this, (3) quantum mechanics can be seen to emerge via the correspondence principle
, as a nonrelativistic approximation for a theory of inertia in relativity.

The result is a continuous

Schrödinger's equation emerges therefrom.[14]
Quoting Sachs, "...by dropping the (unnecessary) space and time reflection symmetry elements from Einstein's field equations, they factorize from 10 independent relations to 16 independent relations. This generalization then yielded a unified field theory of gravitation and electromagnetism. This factorization is entirely analogous to Dirac's factorization of the Klein Gordon equation to yield the special relativistic spinor form of Schrödinger's wave mechanics."

"The well known trouble with

RQFT," Sachs wrote, "is that when its formal expression is examined for its solutions, it is found that it does not have any! This is because of infinities that are automatically generated in this formulation."[8] Through general relativity, he instead produced a myriad of theoretical results without resorting to arbitrary parameters or renormalization, some in closer agreement with experiment than derived from quantum field theory, e.g. for the Lamb splitting with N = 4.[15]

Yet another phenomenon that Sachs' theory can accommodate (that standard cosmology might not) is the Huge-LQG large quasar group, since general relativity does not presuppose homogeneity or isotropy, i.e. the cosmological principle.

Sachs believed that fundamental incompatibilities between

relativity theory and quantum theory preclude there from being a quantum theory of gravity.[16]
