Mathematical Physics With Classical Mechanics By Satya Prakash Pdf ((link)) -

The PDF was traced to an abandoned server at the University of Lucknow, where Prakash had taught until his disappearance in 1972. Not death. Disappearance . One morning he walked toward the physics department, carrying his green bag, and was never seen again.

Newton's laws, kinetic theory, and mechanics of single particles. The PDF was traced to an abandoned server

She opened her laptop. The PDF had grown. It was now 1,247 pages long. It contained derivations for phenomena that didn't exist yet — dark energy as a gauge artifact, consciousness as a boundary term, love as a conserved Noether current under time translation. One morning he walked toward the physics department,

At the very end, a final line:

Methods for solving homogeneous and partial differential equations, including Green’s functions. Key Features Pedagogical Balance: The PDF had grown

Here is a on how to approach this book, specifically focusing on the intersection of Mathematical Physics and Classical Mechanics.
