This is fantastic. I taught a Ukrainian refugee student this year. He was an amazing mathematical mind, too. This is an amazing accomplishment in regular times...but a million times more so given the state of his home country.

Oles Hordiichuk has won a gold medal at the International Mathematical Olympiad in Australia!

Last year, he earned a bronze, and this year he’s ranked first in the world among young mathematicians!

I'm incredibly proud of #Ukrainian kids. They deserve a lasting peace.

This made my day. Thank you. Libraries and those that work there are the absolute best.

Wow, @fawnnguyen.substack.com
Thank you. I like using summertime to reengage, refresh, and remind myself to keep trying new and old things. This was a wonderful post and gave me permission to keep doing the hard work even when it sometimes doesn't go perfectly.

the sine "difference of squares" is more fascinating, but tinkering to find the cosine identity was fun, too

[good fodder for trig next year...]
