Researchers are using supercomputer simulations grounded in Einstein’s relativity to test scenarios about what may have ...

In another book on special relativity, also aimed at high-school students, Les Marder goes straight into a mathematical presentation; his account is both complete and authoritative.

The equations for particles with spin 0, spin 1 and spin 2 — the Klein–Gordon, Maxwell (electromagnetism) and Einstein (general relativity) equations, respectively — readily accommodate real ...
