Goddamn - an exposition from Democritus through to Loop theory. Beautifully explained even if I found myself scrubbing back a few times to try and wrap my chops around some of it (hell, most of it, if I’m honest).
Could I explain it back to you, nope.
Do I understand it from first principles, nope.
Do I have an eloquent and passionately recounted overview of theoretical physics, yes!

My brain is soup now but it makes me want to learn more and isn’t that the entire point of scientific inquiry?

Also, as a sidenote, it is narrated by Roy McMillan who also voiced The Old Ways by Robert McFarlane and I’m hooked.
