Illustration of a polaron in a crystal: the central bright sphere is the charge carrier, distorting the surrounding lattice. The wavy lines represent high-order Feynman diagrams for the ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: This paper analyzes the double pulsing effect based on vector diagram in motor drives with variable modulation techniques. The overvoltage caused by voltage reflection is analyzed in a long ...
