Addicted to Theoretical Computer Science & Quantum Physics. I reeeeeally need to know if a universal quantum computer can be built or not. If so, video games! And if not, why not? Also, P vs. NP, P=RP=BPP, Classical Factoring, A.I.T & Cryptography (AP, KC, OWF, PRG). Gave up on AI, for now. My favorite American Idol? Richard Feynman.
