ABSTRACT:
In his talk, Leggett will discuss the origin of the "arrow," or
direction, of time – what he calls "one of the deepest questions of
physics."

"We all feel that we can remember the past and affect the future, not
vice versa, so there is a very clear arrow of time built into our
interpretation of our everyday experience," Leggett said.  "Yet, the
fundamental microscopic laws of physics, be they classical or
quantum-mechanical, look exactly the same if the direction of time is
reversed."

Leggett promised to "review some relevant considerations, but will not
pretend to give a complete answer" to the question posed in the title
of his talk.

At 10 a.m. the following day, Friday, March 30, Leggett will present a
second talk in the School of Management's Davidson Auditorium on
"Testing the Limits of Quantum Mechanics:  Motivation, State of Play,
Prospects."  This address, which is also open to members of the
public, is designed primarily for audiences with some pre-existing
interest in the foundations of quantum mechanics.
