As a first foot-hold I recommend highly https://detexify.kirelabs.org/classify.html

(I think I saw there was a newer one, but don't remember how)

You draw the symbol and get the TeX symbol name. I tried this one and it does give the right \wp (which in this case is confusing and you'd have to look up more about why it's named that)

But for classic ones, for instance the "upside down A" -> "forall" is very helpful and shakes newcomers to math syntax

Feynman said that his students struggled with a reverse problem: how to know that "harnew", an important part in QM equations that the lecturer talks about, actually stands for hν.

Always thought it was kind of cool how Feynman writes about, when learning calculus and maths as a younger student, would create and use his own symbols for things and how it worked well for him. But kind of realized if he was going to enter the scientific community would need to conform to the standardized notation/symbols for equations etc.

We solved that though, it's now pronounced “(h)aitch-bar-o-mega.”

Everything is easier with a piece of pi!

Detexify appears to be a kNN classifier. https://gist.github.com/kirel/149896/3a13825f826ec91e04d4adb...

This is great, thank you! Would be even better if it had a little "click here to hear it said out loud" button.

Very cool, but I tried a plus ("+"), and it didn't show up in the list, even when I clicked "show more" several times.

Good stuff: worked the first time I tried to draw a ℘.
