new video: "Size of a nuclear blast" is about G.I. Taylor and how to find the radius of a blast wave using dimensional analysis to model the first nuclear explosion. Includes a shout-out to my friend @Dr_SamRigby and the paper we published last year #JK0 youtu.be/8ru_LpjuabY

new video: "Energy of a nuclear blast" is a step-by-step guide to reproduce how G.I. Taylor determined the blast energy of the first nuclear explosion using some photographs. Includes some rebuttals to several myths about this story #JK0 youtube.com/watch?v=wr-e9r…

new video: in "Nuclear Bomb vs. Nuclear Reactor" I show how a nuclear reactor cannot explode like a nuclear bomb and also what happen when you try hard to explode a bomb designed with reactor-like materials #JK0 youtube.com/watch?v=S-uMUq…

new video: "Operation Epsilon: Heisenberg and the German Bomb." The story of the German Uranium Club, their conversations after Hiroshima at Farm Hall, and why Heisenberg got the critical mass for a nuclear bomb so wrong #JK0 youtu.be/6zIJTwQ2blU

For my next video, I just finished solving the neutron diffusion equation and completed a step-by-step derivation of the critical mass for an atomic bomb. My notes are ready to be the MacGuffin of a dystopian time-travel story. #JK0
