Brian GreeneEinstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.
Brian GreeneEinstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quantum mechanics, electromagnetism - all together in one package, but only if the universe has more dimensions than the ones that we see.
Brian GreeneEvidence in support of general relativity came quickly. Astronomers had long known that Mercuryโs orbital motion around the sun deviated slightly from what Newtonโs mathematics predicted. In 1915, Einstein used his new equations to recalculate Mercuryโs trajectory and was able to explain the discrepancy, a realization he later described to his colleague Adrian Fokker as so thrilling that for some hours it gave him heart palpitations.
