Math Twitter: let’s keep it supportive. Favorite integral trick, theorem, heuristic, or “aha” moment? No gatekeeping. I like elegant shortcuts and foundational proofs alike. What made integrals—or any part of math—click for you? 🤓

I grew up in Duxbury, MA (second town founded by the pilgrims... after the first which was Plymouth, of course). I, at least, understand that Thanksgiving is not a "Colonizer Holiday," or whatever silly thing people call it nowadays.
In fact, after being thankful to God, the pilgrims were most thankful for the Wampanoag natives that helped them survive as well as they could that first winter and appropriately prepare for the next year – particularly Squanto, who taught them how to plant, and Samoset (a Sagamore, actually), who acted as an interpreter because he learned many languages with great skill. They were also thankful to Massasoit, the Wampanoag leader.
Yes, bad things happened later. But NOT because of the pilgrims, and in NO WAY related to the first Thanksgiving. It's hard for people to accept, but some tribes were just as bad (or worse) than "colonizers," and some immigrant Europeans were actually pretty nice and had good relationships with the natives.
And the FIRST Thanksgiving is a wonderful example of two different peoples coming together to thank their gods and celebrate the new friends that they had made over the last year!

Here's my attempt at a number systems visual. I decided to leave off Imaginary (you just multiply something by i) and Complex (you just add Imaginary to non-Imaginary). Letters and numbers just get too small to be useful.

There's lots of questions like which is larger, 253²³ or 23²⁵³?
First, a hint: if both numbers are integers larger than 2, the answer is ALWAYS that the (smaller)^(larger) > (larger)^(smaller).
But here are ALL the answers, followed by the proofs.
