Paper: Generalized Second Law of Thermodynamics in Black-Hole Physics — Jacob D. Bekenstein (1974)
Talk Abstract
How can the second law of thermodynamics survive if a black hole swallows entropy?
This talk introduces Bekenstein’s landmark 1974 paper and explains how it laid the foundation for generalized entropy in black-hole physics. Wang Jian will walk us through the main idea of the paper, its bound-based proof strategy, and why its core insight still matters today — in discussions of Hawking radiation, the information paradox, and modern quantum gravity.
All are welcome — no background in GR required, just curiosity! See you there.
