In this video, we explore line integrals in polar coordinates, a key concept in mathematical physics. I’ll guide you through how to set up and evaluate line integrals in polar systems, including ...

Back in 1948, the journal Physical Review published a paper entitled “Space-Time Approach to Quantum Electrodynamics” by a young physicist named R.P. Feynman at Cornell University. The paper described ...

In this video, we provide an overview and summary of Chapter 1 from Introduction to Electrodynamics by David J. Griffiths. We ...

WE are unable to read this treatise, because it is printed in Japanese. The mathematical formulæ and woodcuts show that the author is introducing his students to those elementary geometrical (curve ...
