I was introduced to the game Set years ago at Twitter Math Camp and loved it right from the start. So it's cool to see how the math is deeper than just playing the game. I love the vector space representation. Although they don't talk about it here, another variation is 3D Set. That you play more collaboratively but it's fun too.

🚨New Feature Alert🚨: Our Geometry Tool now includes vectors you can compute with in the expression list! How will you use our new vector tool? (Bonus: What do you notice about the vector tokens in the expression list as we move the vector around?) pic.twitter.com/5gtKZAxMOB

With the exception of a single symbol for ⅔, Ancient Egyptians’ number system could only express more complicated fractions (like ¾) as sums of unit fractions, which are fractions that feature a 1 in their numerator (½ + ¼). https://t.co/9J6evWPqzo pic.twitter.com/TJmRojyo9L

I once tried to figure out my Erdos number based on my Masters work in Physics. I think I might be too far away but it's still pretty cool how much he did for math and physics

Mathematician Paul Erdős used to work for nearly 19 hours a day doing math and often claimed that he requires only three hours of sleep. He published nearly 1500 papers on mathematics and co-authored with more than 250 mathematicians during his time. Erdös is credited for… pic.twitter.com/0nxKOWGmUf
