The Many Faces of Time
Time is multifaceted: this talk is designed to expose the various, quite
distinct features of time that physicists and others have grappled with in
recent centuries. Why do we remember the past and not the future? What
does it mean to say two events are simultaneous, and why did Einstein say
that simultaneity is relative to the observer? How do we know that a
definite period of time elapses between two events? Why did Einstein say
time "dilates" when clocks are in motion and when they rise in the Earth's
gravitational field? I will try to explain why this miscellany of issues
is so important.
