... Problem(s) of Spacetime: “If one assigns the intrinsic 3-geometry, one cannot also specify the extrinsic curvature. The uncertainty principle thus deprives one of any way whatsoever to predict, or even give meaning to, 'the deterministic classical history of space evolving in time'.” (C.W. Misner, K ...

Schrodinger equation (PPT - 7.3MB)
... A system is completely described by a wave function ψ, representing an observer's subjective knowledge of the system. The description of nature is essentially probabilistic, with the probability of an event related to the square of the amplitude of the wave function related to it. It is not possible ...

Introduction: what is quantum field theory ?
... Yet another reason to treat fields as the fundamental physical quantity is that all particles of the same type are the same. This is much more serious than it initially sounds. For example, two electrons are identical in every way, regardless of where they came from and what they’ve been through. Th ...
