I’ll get straight to the point, on average the first Premier League manager is sacked after 77 days.

About a year ago I wrote a post examining the data when Rooney become England’s highest ever goal scorer. Now he has become the most capped outfield player I thought I should update the stats.

From the Premier League this season (2015/16) Aston Villa, Newcastle United and Norwich City were relegated. This represents the largest capacity of stadia relegated from the division since only 3 teams were relegated (a total of 122,331). This post contains the data (stadia capacity) for each of the relegated teams, since the 1995/96 season.

First we assume that we do not allow the trivial answer where \(n=m=q=0\). Then rewrite the equation as: \[2^n + 3^m = 5^q+1.\] Now \(2^n\) must be even for […]

The branch of mathematics invented by Euler, this theorem is known as Euler’s Formula. It is a remarkable fact that for any planar graph (edges only intersect at their endpoints) the number of faces (regions […]

Mostly this comes from people who have watched the incredibly successful Numperphile video, but the result was well known before then. There are a number of ways to ‘prove’ this result, giving rise to […]

Well, yesterday, we found a new largest. \(2^{74207281}-1\) is the 49th Mersenne Prime that has been found. It is 22,338,618 digits long (click the link to download the whole number, be warned though, the file is […]

For the value \(n=2\) this is the well known Pythagoras theorem. A simple theorem to state, but […]

I’ve been using a branch of statistics called ‘Extreme Value Theory’ in order to come up with a statistical analysis of extreme space weather events. This approach has been used in a variety […]
