For 10 points, name this principle of quantum mechanics named for Heisenberg, that explains why position and momentum of a particle cannot be measured simultaneously.
In its most general form, this statement is written as "standard deviation of A times standard deviation of B is greater than or equal to negative i over two times the commutator of A and B." A thought experiment of observing an electron through a gamma-ray microscope justifies this statement that can measure the lifetime of a virtual particle.
