This repository is forked from eigencrish, a brilliant instructor. My BS Math final year project, titled "Two-Body Problem in Newtonian and General Relativistic Mechanics," benefited greatly from these notes. They helped me understand tensor calculus and general relativity. Highly recommend them!

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 79 stars here means stars gained during the window, not the repo's star count.
