Thanks King Vitamin. Yes I've only had a semester of QFT and even that is a rare offer at the University I went to. We worked up to and through being able to do a few QED processes and deriving Feynman Diagrams from operator methods but did not go further than that. When I've gone back to the...

Can Lagrangian densities be constructed from the physics and then derive equations of motion from them? As it seems now, from my reading and a course I took, that the equations of motion are known (i.e. the Klein-Gordon and Dirac Equation) and then from them the Lagrangian density can be...

My astronomy lab group is planning a research project. We will have access to a .6 m reflecting telescope in the northern hemisphere as well as I believe a .6 or larger reflector in Australia remotely. We are curious how likely or practical it would be to be able to find research subjects...

I have been thinking about how to come up with a function of time for the n-body problem. Later I found that there still is no function of time known for the n-body problem, but I am still not sure where the brick wall for everyone is because I am quite sure my understanding has hit from very...

Hi, {First off I should share my ultimate goal, which is to have a position function of time of several bodies, let's say in a solar system, so that the position of each body and the acceleration due to gravity on all the other bodies in the system are given at any time t. Although Kepler's...
