Let's do some math

I found myself casually tuned in to a few of these. Really nice, relaxed lessons.

I'm not embarrassed to say that this guy helped me get through my MSc. I don't know how they did it back before Youtube and the Internet at large (though back then, none of the technology I worked on would have been possible).

I needed this for the Calculus class I got a D in (again), but I found I liked blackpenredpen the best, as well as this mysterious Sal person. Khan Academy doesn't seem very forthcoming with teacher's names (not all Calc I Khan videos are by this guy). I was already stressed so these no-nonsense tutorials were right up my alley, where 3Blue is more expository. I probably would have gravitated more toward him if my class was online-only and I wanted some lecture time behind my homework.

I love that guy. I haven’t watched him for a while but I absolutely love that he exists and that I know he exists.

We spent a lot more time in libraries. As an undergraduate math student I remember getting desperate enough to look through the books written in german and such, because usually the formulae were still decipherable. It sucked.

I wish stuff like this existed when I was in high school and a huge math nerd. YouTube sort of existed but not with the sheer quantity and quality of stuff you can find with a little poking about.

I found a lot of it eventually, but mostly in dusty books and the occasional video set I managed to find in weird academic corners of the internet.

or at least no less undecipherable

Nope, definitely still less.

Lockdown math? No better time for Lockhart's Lament about the parlous state of mathematical education in 2002 (and before and since, I guess). 25 page PDF. “Mental acuity of any kind comes from solving problems yourself, not from being told how to solve them.” Snippets for folk who prefer short-form. Lockhart Metaprev.

In a (soft of) similar vein, you might also enjoy WooTube, from Sydney high school teacher and education leader Eddie Woo.

Oh, Grant is wonderful! He and I were part of the same cohort at Khan Academy; we both started in the fall of 2015, and our desks were right next to each other. Somewhere floating around the internet is a clip of him explaining Hilbert's Infinite Hotel to me.

I'm so proud of the work he's gone on to do! He's such a smart, sensible man, and he's managed to do something very difficult: create a successful business as a math celebrity on the internet. I find his videos very calming and reassuring, and I can tell you that he's very kind in person, too.

I clicked on the "Logarithm Fundamentals" link and spent five minutes being told that "The lesson will begin shortly"

That's really lame.
