Did you know Pi Day (March 14) started in 1988? The date was chosen because the first three digits of pi are 3.14. March 14 is also Albert Einstein’s birthday, so that’s a fun coincidence. (There are other dates that you can celebrate pi. Check them out: https://www.timeanddate.com/holidays/fun/pi-day).
It seems like it’s gotten more popular in the age of the Internet. People who never cared much for or about math will happily post pi memes on Pi Day. I think that’s great. If it brings some positive attention to math and math topics, I’m all for it!
