Also. Google the mathematician pictured. (Alexander Grothendieck) Turns out there is a name for numbers that are not prime but feel like they should be.

I know some of you have been wondering about my posts in the last 12+ hours. I am just humoring myself. But I know some of you are worried - here is my proof - within a couple of hours I received these texts from my sister, brother and mom. More soon to connect all the previous posts today.

My age today is NOT a prime number, BUT a lot of people think my age is a prime number? How old am I? #mtbos #teachmath #mathstoday

Yes I made a homemade ‘Happy Perfect Square Day!’ pin to wear today. Do something that involves a right triangle today & let me know what it is. #iteachmath #mathstoday

I know three people whose birthday is today. I told them that they should celebrate at 1:04. =)

I just learned from a math teacher that it is a day: Perfect Square Day!

And this is a special one for this century, because 2025 is 45²

9 days until Perfect Square Day! I know 9/9/25 is a perfect square, but 9/16/25 hits a bit different as it connects with a 3/4/5 right traingle. On another note, I made my nephews pose for this pic when the turned ages 3, 4 & 5.

1 day! Does it have to be squares off of each side of the triangle? Also, my nephews at ages 3, 4 and 5. Enjoy. #iteachmath #mathstoday #mtbos docs.google.com/document/d/1...
