Four-vectors and conservation laws in relativity
This lecture was delivered to the final year honors class of 3 year science degree students on 21 November 2017 as part of the Classical Dynamics paper. In this lecture we will discuss some of the important tools of relativistic mechanics. We will discuss the idea of proper-time, 4-velocity, 4-acceleration, 4-momentum, 4-force and related conservation…

Relativistic Doppler effect
Relativistic Doppler effect. There is an apparent shift in the observed frequency of any electromagnetic wave (light) when there is any relative motion between the source of light and the observer. This can be easily determined by using the 4-vector formulation of theory of relativity. Lets discuss the details of this phenomena under two situations.…

Feynman Diagram of Higgs Boson Production.
This is a copy of the diagram from Wikipedia. I produced this using codes developed by me as previously instructed here with other examples. — What to do when its 2 am around here, you are fresh but nowhere to go. Here is the code: % Feynman diagram % Requires PGF >= 2.0 \documentclass{article} \usepackage[latin1]{inputenc}…

Creating Feynman diagrams with Latex.
I have successfully installed Cygwin, GV, GS, MikTex, Lyx etc on my win-07 Vaio. So I want to check to see my Cygwin functionality on some physics exercises. The following link is broken now. Feyntex at Colorado. — Somehow I could not produce this and another simple example for Feynman’s diagram using the codes here and…
