You meet up with a slightly familiar mustached squid “man” He may or may not have bankrupted you infinitely times over in the past, but you’re over it. In fact he has a new deal for you! Every day he will modify your bank balance in one of two ways. With probability 0.6, your balance […]

Elections never really feel fair (or, if talking about the electoral college, are never fair) Here is an example, say there is an internal election in some political party, to determine the order of members of the party. To do so, each voter votes for their favorite party member, and the party members are ranked […]

Happy Holidays! Here are a couple Christmas and Hanukkah puzzles just for you: The 2n-Menorah: In an alternate universe, instead of the flask in the temple lasting for just 8 days, it lasted for 2n days for a positive integer n. Thus, Hanukkah in that universe is celebrated for 2n days, and the menorah has […]

You know periodic functions right? Functions that after a certain place start repeating, for example sin(x): More formally, a function f is called periodic is for some constant p>0, f(x+p)=f(x). In other words, shifting by p does not affect f(x). The constant p will be called the period of the function (sometimes we say f […]

You may have seen one of the following viral math facts: The first fraction seemingly gives the Fibonacci numbers. That is, the sequence of numbers that starts with 1, then 1, then each successive term is the sum of the two prior terms. So the first few Fibonacci numbers are 1,1,2,3,5,8,13,21,… Which appear on the […]
