As a huge fan and patron of 3blue1brown's videos, does anyone have recommendations for similar high-quality channels covering other topics? Personally I'm interested in at least:

* History/biographies

* Sciences (physics, chem, astronomy)

* In-depth nonpartisan analysis of political situations, especially current ones. The breaking news cycle does a poor job parsing out useless or incorrect information.

* How we've managed to create the insanely complex technology we have today, starting at the basics
