Sometimes the most interesting puzzles are, on the surface of it, the most simple. I bet if we all have a look at the 5 Pirates puzzle and the Monty Hall problem we'll end up arguing
Which is the monty hall problem?

You're on a gameshow. The host shows you three doors and tells you that behind two of them there are goats and behind one of them there is a car. You pick a door, and the host, who knows what is behind the doors, opens another door to reveal a goat. The host then asks if you would like to change your choice.I do not understand what is so confusing about this problem but it has inspired a lot of debate...

I'm assuming this was an actual game show? I think there was a number phone video on this as well....

From Wikipedia: "loosely based on the American television game show Let's Make a Deal and named after its original host, Monty Hall."
It gained fame when it was posed to Marilyn vos Savant in a magazine column. She got the answer right and was met with a torrent of angry letters claiming she was wrong from many people, including PHDs lol.

lol, might watch some videos on the show, game shows are suprisingly fun, especially when it's on YouTube so you dodge all the ad breaks etc

9. M1/M2 Statics and Dynamics, C2 Logs and FP1 Proof By Induction
10. Not very fun, but I found it quite interesting when we visited colleges and the teacher made us look like an idiot. So, the teacher created two Mobius loops: one with one curve in it and the other with two curves in it. Then, she asked us to cut down the middle to create two loops - made us look like right idiots when half the class had tangled their paper up.
11. That some infinities are bigger than others by using the infinite hotel paradoxes
12. 3x3 Matrices and also the 3x3 Eigenvalues of Matrices
13. Lagrange multiplier - used extensively in my microecon modules.
14. Maybe, Inversion in Geometry.

20. Differentiation with volums I found interesting, I really like d1 and d2 though, and how they can be used in real life, such as transportation costs or shortest networks ect. Though I was terrible at d2, i found it interesting. I really liked the differentiation in fp2 as well. Integration of area's was interesting, I think that's about it off the top of my head, I prefer economics tbf
