Recently, Roy Kerr claimed that Roger Penrose's Nobel prize-winning singularity theorem was wrong. This was widely hyped. But here, Roger Penrose and other leading relativists point out that it was Kerr who is in error. How did everyone get it so wrong ?youtube.com/watch?v=foq4nVAw…

The Reinvention of Science

It is a very well-written and enjoyable read that is strong on accuracy as well as being accessible and pedagogical. I congratulate the authors on a really excellent book.

Fascinated to read this about liquid mirror telescopes (which I know nothing about) mainly because Henry Skey was my great grandfather. Unique liquid-mirror telescope set to survey zenith in India astronomy.com/news/2022/08/u…

Unique liquid-mirror telescope comes online in India

Instead of a glass mirror, this telescope uses a spinning pan of liquid mercury.
