I know John Baez.  John Baez is a friend of mine.

See if anyone recognizes that allusion.

Seriously, Hywel White, Barry MacKichan, Jon Zingale  and I read Baez's book "Gauge Fields, Knots and Gravity" a year or two ago.  He begins in the first section by showing why one forms (and higher order forms) and manifolds are better than vector fields for doing physics.  It's because they work in higher dimensions better.  Then in the second section he develops the math of gauge fields bundles and connections.  In the third section he develops models of gravitation using semi-Riemannian geometry.

I understood 90% of the first section 50% of the second and 20% of the third.  I understood the math much better than the relationship of it to physics.  Hywel probably would say the opposite.  I'll let Jon and Barry speak for themselves.

Wasn’t John Baez doing this stuff in the late 90s?

What do you think of Stephen Wolfram's latest findings? It is always interesting to see what he is doing IMHO
