Einstein's Vision and the Quantum Universe
James Hartle
University of California
Santa Barbara
Albert Einstein was a great pioneer in the quest for the fundamental laws that
govern the regularities exhibited universally by all physical systems, without
exception, without qualification, and without approximation. We will discuss
Einstein's vision for the nature of these laws and for their discovery by a
process of abstraction, generalization, and unification guided by mathematical
elegance. The discovery of his theory of gravitation --- general relativity ---
will illustrate this vision. But Einstein's vision has had to be modified to
accommodate the quantum mechanical laws of microscopic physics. We will discuss
the implications of quantum mechanics for the nature of the fundamental laws,
for our picture of the the universe on the largest scales of cosmology, and for
our understanding of the origin of the universe in the big bang where large and
small are one. Lessons for the nature of scientific authority will be drawn.

James B. Hartle is Professor of Physics at the University of
California, Santa
Barbara. His scientific work is concerned with the application of Einstein's
relativistic theory of gravitation --- general relativity --- to realistic
astrophysical situations, especially cosmology. He has contributed usefully to
the understanding of gravitational waves, relativistic stars, and black holes.
His current interest is the quantum origin of the universe and the
generalizations of quantum mechanics necessary for that. He is a member of the
US National Academy of Sciences, a fellow of the American Academy of Arts and
Sciences, and is a past director of the Institute for Theoretical Physics in
Santa Barbara.
