Here's what I'm up to now (last updated on 2021-01-13):

• teaching
  • linear algebra, using Linear Algebra Done Right by Sheldon Axler
  • calculus, using Calculus by Michael Spivak's
  • differential topology/geometry, using Introduction to Manifolds by Loring W. Tu
  • group theory, using Abstract Algebra by David Dummit & Richard Foote
  • category theory, using Category Theory by Steve Awodey


• watching
  • Lectures on Geometrical Anatomy of Theoretical Physics, a lecture series on geometry in physics by Frederic Schuller
  • Introduction to Renormalization, a lecture series by Simon Dideo


• reading
  • Functional Analysis by Peter D. Lax
  • Gauge Fields, Knots and Gravity by John Baez & Javier P. Muniain
  • A First Look at Rigorous Probability Theory by Jeffrey S. Rosenthal
  • The Constitution of Phenomenal Consciousness: Toward a Science and Theory edited by Steven M. Miller

I got the idea for a "now page" from Jakob Schwichtenberg, who got it from Derek Sivers.
