RE: The Euler-Lagrange Equation - Quantum Field Theory
Hi @zizelevak. This is a well known formula (check out the wikipedia links in the article). I'll try to figure out how to explain it in "plain english" but it might take some time :)
Hi @nonlinearone
I was looking at wikipedia :) I was badly reading your handwriting. I read dL in your formula as dZ.
In your formula is Lagrangian L(t,a,v) = (mv^2)/2 - mah ? I am correct?
Sorry, I have a strange way of writing the "curly L" which is used to represent the "Lagrangian density". You are on the right track for what "L" is but its a bit trickier. On mobile device right now so cant explain fully... may have to do another post :) So glad you are looking into it, makes my day.
See near 1 minute 20 seconds in this video for an example of what a Lagrangian density used by a field theorist looks like https://steemit.com/science/@nonlinearone/physics-out-loud-broken-symmetries-and-the-masses-of-gauge-bosons-by-peter-w-higgs-1964
