A reasonable guess is that momentum is a 3-vector conjugate to position, so we need to find what the fourth component is to make a 4-vector. 1970-10-12 In that case, though, its momentum squared must be exactly p 2, which is the eigenvalue you get by acting on Y p with the momentum operator twice. So in the end, it's not quite as arbitrary as it first appears. (Of course, this is not a proof of anything, but hopefully it's a helpful hand-wave.) In this lecture, Prof. Adams begins with a round of multiple choice questions.

Four momentum squared

Equating the squares of the 4{momentum of the decaying particle before the collision and the square of the sum of the 4{momenta of the decay particle and emitted photon after the collision, remembering that the square of the 0th component gets a minus sign due to the sign of the 00 metric The Heisenberg uncertainty principle defines limits on how accurately the momentum and position of a single observable system can be known at once. In quantum mechanics, position and momentum are conjugate variables. Fourier transform. One can show that the Fourier transform of the momentum in quantum mechanics is the position operator. The The squared four-momentum is a scalar invariant, i.e., it doesn't depend on any reference frame. Thus a relativistic invariant theory requires a formulation based on invariant quantities.

Four-momentum is the special relativity analogue of the familiar momentum from classical mechanics, with the property that the time coordinate of a particle's four-momentum is simply the energy of the particle; the other three components of four-momentum are the same as in classical momentum.
