Brian Greene : (5) " Physicists are more like avant-garde composers, willing to bend traditional rules… Mathematicians are more like classical composers. " - Brian Greene " By dimension, we simply mean an independent direction in which, in principle, you can move; in which motion can take place. In an everyday world, we have left-right as one dimension; we have back-forth as a second one; and we have up-down as a third. " - Brian Greene " Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later. " - Brian Greene " I like ‘The Simpsons’ quite a lot. I love the irreverent character of the whole show. It’s great. " - Brian Greene " Supersymmetry is a theory which stipulates that for every known particle there should be a partner particle. For instance, the electron should be paired with a supersymmetric ‘selectron,’ quarks ought to have ‘squark’ partners, and so on. " - Brian Greene
