Been catching up reading #astrobites.
Nearly missed this little gem about Penrose Diagrams.
Prof. Sir Roger Penrose did this seminal work in 1963, now, these diagrams are an important tool in #physics when trying to understand causality in general relativity.
Sir Roger continues to do important, interesting, and somtimes controversial work in physics, #maths, #consciousness & #computability.

I can so easily relate to this. I used to enjoy going on random drives to see where it got me. I would like to try a levy-walk but will wait for it to be cooler. Too hot!
But hopefully it will rain soon ...

Fascinating. I was familiar the number of bounces of sliding blocks can be made to represent the digits of #pi, but this adds another twist.
