Steal this idea: a Shazam of mathematical notation. In an app you would draw (or take a picture) of a mathematical symbol you don’t recognize and get a link to the appropriate Wikipedia page.

My biggest pet peeve with mathematical symbols is the difficulty of looking them up when you don’t know them already. If I’m reading a text on a topic I'm unfamiliar with, I can at least google the keywords I don't know. This is difficult with symbols.

Great idea. I'm a fan of this app/site for finding the Latex command for a particular symbol:

Then just need to look up the Latex on Wikipedia:

you could try something like https://mathpix.com/ and then look up what the LaTeX symbol is.
