I love many. This is my newest favorite

Sharing another intriguing physics paper :

I have long been fascinated by Paul Ehrenfest's 1917 article showing planetary systems are virtually unstable for any dimensions of spacetime, other than d = 3+1

Since I am new here, I thought I would continue my tradition of sharing pedagogical review articles about important topics in theoretical physics & Cosmology.
I begin with this excellent review of Cosmological Constant by Jerome Martin, I have personally found illuminating.

At Lancaster University this week to give a Cosmology Seminar on 'Reheating after inflation and formation of Oscillons'.

I am new here. Looking forward to reconnecting with my old Twitter (X) colleagues to continue discussions on Physics, Mathematics and the Universe.
