Leo and I do a lot of our learning from YouTube (as does everyone these days, of course!) In other posts I’ve listed some of the channels we subscribe to, and I should update that. But I want to give a shout-out to three terrific science ed channels, and to one specific video on each that just blows my mind about how great scientific and mathematical explanation can be:


VSauce (which has several sub-channels now) is chocked full of terrific scientific explanations, but this one is just head and shoulders above anything that I’ve seen anywhere else:



Although way less broad than Vsauce, the mathematical explanations in 3Blue1Brown are the best I’ve ever seen, anywhere. This one is particular mind-blowingly clear about a particularly mind-blowing part of the core of mathematics:



Much more boring in style than either the above two, and much much more detailed, Dr. Physics A does the clearest detailed physics derivations I’ve ever seen. He works through all the algebra step-by-step in what should be really really boring, but for some reason that I don’t get, it actually really really gripping. (Something about his “Queen’s English” accent adds to the fun; like you’re getting your physics from James Bond 🙂 All of his videos are great, but this little 5-parter that goes from zero to E=MC^2 is just so crystal-clear I can watch is again and again and just appreciate more and more how great explanation can be:


Honorable mention to PBS Space Time. Unfortunately, they’re a little long for their depth and detail. Even though it’s just pen-and-paper, compared to Space Time’s fancy CGI, Dr. Physics A wins hands down on coming out the other end understanding what’s really going on. (The Space Time guy also has a sort of cool accent; I think it’s also English (as in British), but not as “Queen’s” as Dr. Physics A, so not as much fun.)
