A Whimsical Introduction to Graph Theory (1)

Part 1 - What are Graphs? Mathematics is full of fascinating ideas and concepts. These can, however, be very challenging to tackle and make sense of, especially when you are put under pressure to answer questions about them! In this post, and those to come, I hope to share some [...]

e-day – A mathematical holiday celebrated on February 7th

Today, February 7th, 2018, is called e-day because e is approximately 2.718, and this date is written 2/7/18 in some parts of the world. e, also called Euler’s Number after the Swiss mathematician Leonhard Euler, is a very important constant that comes up in many different places in mathematics. The numer e was discovered by the Swiss [...]

Can you find a simple proof for this statement?

I thought more about the last question I added into the addendum of the Numberphile, Graph theory and Mathematica post It can be succinctly stated as: $latex (\forall m\in\mathbb{Z}, m\ge 19) (\exists p,q\in\mathbb{Z}, 1\le p,q<m, p\ne q)$ such that $latex \sqrt{p+m}\in\mathbb{Z}$ and $latex \sqrt{q+m}\in\mathbb{Z} $. In words: For all integers [...]

Graph Theory, Numberphile and Mathematica

Edit: I made a mistake with some of the language here. A comment from a true graph theorist: "Hamiltonian" usually means there's a hamilton/hamiltonian cycle. Graphs with a hamilton path are "traceable". Hamiltonian implies traceable, but not conversely. Thus, I have edited below accordingly. ------------------------------- There was a nice video [...]
