Category Theory Illustrated - Logic
Logic Now let’s talk about one more seemingly unrelated topic just so we can “surprise” ourselves when we realize it’s category theory. By the way, in this chapter there will be another surprise in addition to that, so don’t fall asleep. Also, I will not merely transport you to a different branch of mathematics, but to an entirely different discipline - logic. What is logic Logic is the science of
Abel: The Mozart of Mathematics
Niels Henrik Abel (1802–1829) died at the modest age of 26 years old. Largely self-taught, in his short life the young Abel made pioneering contributions to variety of subjects in pure mathematics, including: algebraic equations, elliptic functions, elliptic integrals, functional equations, integral transforms and series representations. Born on the small island of Finnøy in Rogaland, Norway, the

The Math of Card Shuffling
The Math of Card ShufflingRiffling from factory order to complete randomness. You’ve probably seen a few ways to shuffle a deck of cards. Sometimes the deck is split in half and the halves are switched. Sometimes the deck is smooshed until it’s all mixed up. But most of the time, a deck of cards is shuffled using a riffle. Here’s a question: how many times do you have to riffle a deck of cards bef
Day Tripper - Futility Closet
A letter from Lewis Carroll to Nature, March 31, 1887: Having hit upon the following method of mentally computing the day of the week for any given date, I send it you in the hope that it may interest some of your readers. I am not a rapid computer myself, and as I find my average time for doing any such question is about 20 seconds, I have little doubt that a rapid computer would not need 15. Tak
Introducing Logicola 3
LogiCola is a software designed to help students learn logic. It was created by Harry Gensler, who also authored Introduction to Logic (Routledge 2017, 2010, 2002), one of the most well-known textbooks in the field, for introductory and intermediate logic courses. The textbook and software are still present in many introductory courses to logic around the world. Including the one taught at my univ
Stein's example - Wikipedia
In decision theory and estimation theory, Stein's example (also known as Stein's phenomenon or Stein's paradox) is the observation that when three or more parameters are estimated simultaneously, there exist combined estimators more accurate on average (that is, having lower expected mean squared error) than any method that handles the parameters separately. It is named after Charles Stein of Stan
