In this level-0 post, we figure out how many ways we can organize a gift exchange.

## The Universe is not Locally Real… Wait, What?

In this level-0 post, we discuss the latest Nobel Prize in physics, awarded to Alain Aspect, John Clauser, and Anton Zeilinger “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science,” the significance of their experiments, and what it means for the universe to not be locally real.

## When is a Pi not a Pi?

In this level-0 post celebrating Pi Day, we are talking all about circles in weird spaces! In particular, when is the ratio of the circumference of a circle to its diameter not equal to 3.14159(etc)? Ceci n’est pas une pi, as they say.

## The Demons that Haunted Maxwell

In this level-0 post, we take a look at some interesting thought experiments in thermodynamics, in particular the various incarnations of Maxwell’s demon. These were constructed as possible ways to subvert the second law of thermodynamics, and here we will talk about why they don’t.

## There’s Something About Gamma

In this level-1 post, we take a closer look at Euler’s generalization of the factorial, and see how it makes sense even when it blows up.

## Black Holes Win Again!

In this level 0 post, we take a look at one of the contributions of recent Nobel prize-winner Sir Roger Penrose. In particular, we’ll discuss the famous spacetime diagrams which bear his name.

## Root-finding Fractals II

In this level 0 post, we revisit Newton’s method and the fractals it creates, but this time, we focus on generalizations of Newton’s method. This one’s for the people who love to look at fractals.

## Root-finding Fractals

In this level 0 post, we will investigate Newton’s method for finding the roots of a function. Then, we will see how this process can induce chaos and find some fractals hidden inside.

## Crossing the Street – Pt. 3

In this final part to our level 2 mathematical modelling series, we move to a different way of solving our street crossing problem: numerics. We go over discretization of the problem, how to simulate it, and compare with results from part 2.

## Crossing the Street – Pt. 2

In the 2nd part of this level 2 mathematical modelling series, we take a look at what sorts of analytical tools we have to address the problem of how best to cross the street.
