The Summer of Math Exposition (run by 3blue1brown) contest is up and running: https://some.3b1b.co/

As you can see in their rules, it should be accessible to a wide variety of audiences. What might make a good topic for a mathematics blog/video entry?

- Look at some books from Martin Gardner, Stanley Ogilvy, or others, reference these and expand some math tricks in a different way or video explanation.
- Find some new math article on WIRED or Science or other mathematical journals… see if you can expand upon or explain it in a different way.

Summer of Math contest previous winners and runner-ups are here for some inspiration. Now let’s get out there and teach some math!
