'A Universe From Nothing' by Lawrence Krauss: https://www.youtube.com/watch?v=7ImvlS8PLIo

This is a bit outside of technical stuff, but if you like political/social commentary, I think ContraPoints has really entertaining and also fairly well-researched video essays. She is definitely part of the left, but I think people of most political persuasions can find her engaging and funny, even if they don’t agree 100%.

Any Ben Eater videos really, but this is a good one.

The Biggest Ideas in the Universe by Sean Carroll, an intro to modern physics, including homotopy and quantum field theory. He does some math but you'll follow if you've finished high school. Don't miss the Q&A videos in between the 26 regular episodes.

Every Frame A Painting. A great channel (that I wish was getting new videos) going deep on about aspects of moviemaking, editing, musical scores etc. High production quality videos and interesting even if you’re not a film buff or movie nerd.

This channel goes deeply (well, as deeply as is possible) into ballpoint pens, fountain pens, and other writing instruments:

How The Economic Machine Works by Ray Dalio comes to mind. It's 31 minutes long and provides a great high-level overview of basic economic principles.

I love how he explains his thought process and explains the principles that guide decision making.

I can watch him for hours.

I'm not generally a fan of made-for-youtube, but they do have some classic documentaries on there. Including "the most expensive factual series ever made", https://en.wikipedia.org/wiki/The_World_at_War . Made in the 70s, it was long enough to regard it as history but recent enough that senior participants were still alive and available to be interviewed.

The unanswered question series by Leonard bernstein. Great stuff for studying the evolution of western classical music and its parallels with intellectual movements till the rise of 20th century nihilism.

I just got started into wildlife photography and this video has been a great starting point for me - https://www.youtube.com/watch?v=R9YBeNBoKVw

It is long, but goes into a lot of details on what makes a photograph look good.

How to Speak, Patrick Winston: https://www.youtube.com/watch?v=Unzc731iCUY&ab_channel=MITOp...

(And, more generally, just any/all of the MITOCW stuff.)

Not exactly designed for YT, but Sapolsky’s Human Behavioral Biology is great.

Some History and Tech topics

Fall of Civilizations - multi-hour documentaries on historical events and, well, the fall of civilizations. The one on early Sumer is brilliant.

Kings and Generals - brilliant episodes on Military History around the world and big time span. E.g. one in Caesar's Gallic campaigns is brilliant.

Code-report - Programming, APL introduction, book workshops on books like SICP.
