It is derivable from the Cramer-Rao relation, in which its variables are present as Fisher information. Its standard formulation is known as the Weyl formulation, and when it concerns the field strength and the number of particles, it is responsible for virtual particles. Einstein said that it proved quantum mechanics is "incomplete," and the paper in which it was first presented attempted to disprove the law of causality by claiming that it is impossible to know present conditions. Obeyed by conjugate pairs of variables, for 10 points, identify this law which places a lower bound on how sure you can be of the values obtained from the simultaneous measurement of complementary observables.
