DESCRIPTION:G. 't Hooft\, University of Utrecht\, Netherlands\n\nAtte
mpts to arrive at consistent theories combining\n Quantum Mechanics
with General Relativity not only require new\n concepts of space\,
time and matter\, such as the ideas that lead\n to Superstring The
ory\, D-brane theory and M-theory\, but they\n may also require a r
econsideration of what Quantum Mechanics\n itself really is about.
Although completely deterministic\n scenarios appear to be ruled ou
t by the Bell inequalities\,\n it is nevertheless worth-while to in
vestigate a set-up where\n we start with a deterministic theory and
add to this the\n notion of information loss. Although models prop
osed so-far all\n show deficiencies of some sort which makes them u
nrealistic for\n describing the real world\, these models do show h
ow chaotic\n phenomena in a deterministic theory might be suspected
to lie\n at the basis of the quantum nature of our world.
