Buffon’s needle Problem, which was first posed in 1777 by its namesake Georges-Louis Leclerc, Comte de Buffon, is a fantastically simple problem which allows us to calculate, or at least approximate, the value of π through a simple experiment. It can be stated in many different formulations, but we will…

*By calculating a very simple integral we can see that π ≠ 22/7 regardless to what we were told in school.*

I constantly have students coming into my college classes and trying to interchange between π and 22/7. Let’s be clear, 22/7 is a relatively good approximation for π (it…

In a previous article, I discussed how a division trick won me $100.

In this article, I want to show you how similar tricks can be used for other numbers.

Originally I planned to prove how some of these tricks worked, but in talking through the tricks for other numbers…

Let me first clarify, when I said my math teacher, it wasn’t my regular math teacher, who was a wonderful woman and an excellent teacher. Instead, it was a substitute who embodies everything wrong with teaching. This substitute, let’s call her Miss Y, was arrogant, impatient, and simply did not…

In this article, I want to discuss a recent problem a student provided me with. According to the student, this problem comes from a set of Swedish Mathematical Olympiad problems, although I am unsure what year.

The problem is the following:

Find all integers n such that

A few nights ago my partner had me sit down and watch the movie “Mean Girls” with her. For those unfamiliar, near the end of the film, the lead character is involved in a math competition in which two teams face off to answer questions for the state championship. We…

In this article, I want to discuss one of the earliest problems which completely changed my viewpoint of mathematics and pushed me to pursue a career in it.

This problem is from the 2009 British Mathematical Olympiad which I first came across when attending a problem session ran by my…

In this article, I present a formal proof that the recurring decimal 0.999…. is in fact equal to 1. In doing so, however, I will sidestep a little of the more formal notation and strictness that a truly airtight proof would require. …

In this article, I present 14 interesting math facts that I have gathered over the past few years of teaching. I generally present a collection of these to first-year students on their first day to ease them into college and also to just get them thinking. Some of these are…
