In this lecture which is quite good in my opinion Neil Turok claims that all known physics fits into this equation: What is this equation's name? When was it cobbled together and by whom? How confident are you of its predictive power? Do all known physical laws reduce to this equation? Even such laws as the ideal gas equation, Bernoulli's equation and the law which causes liquid water to be denser than ice? I won't bother to understand the finer points of the equation since I barely understand QM much less QED.
