Zak's Lab
Physics and Math with an emphasis on WHY.Zak's Lab is primarily a physics and calculus instruction channel with hundreds of short lecture and example videos currently covering:
Physics I and II (trig-based). This crosses over to AP physics.
Physics I (calculus based).
Physics II (calculus based) is in progress.
Calculus I is coming Spring '24.
Calculus II

I also like making math animations and algorithmic art, and those each have their own playlists as well.
