Brian Greene Quotes:
Ocupation: Theoretical Physicist
Life: b. February 9, 1963
Birthday: February 9
General relativity is in the old Newtonian framework where you predict what will happen, not the probability of what will happen. And putting together the probabilities of quantum mechanics with the certainty of general relativity, that's been the big challenge and that's why we have been excited about string theory, as it's one of the only approaches that can put it together.
