Just spotted that David H. Bailey has started posting "simple proofs of great theorems" on his blog: http://mathscholar.org/2018/09/simple-proofs-of-great-theorems/

This proof that π is irrational is about as straightforward as it can be: http://mathscholar.org/2018/09/simple-proofs-the-irrationality-of-pi/

I invented a puzzle for the radio that didn't get used, so of course I put it on my blog instead.

Please have a go at it!

It is amazing how welcoming IHP is. If you have a day to waste in Paris, you can just walk in here and do math all day.

[Clever Hans II completes his proof of the Riemann hypothesis, puts down the chalk, and flicks his mane. The room around me bursts into applause.]

Me: "Big deal. He only knew when to stop by watching our expressions."

When interpreting letters as their Scrabble scores, the vector "EIGEN" is an eigenvector of this matrix:

\[ \begin{pmatrix} K&E&E&P&U \\ C&A&L&M&M \\ A&N&D&X&Z \\ M&U&L&T&K \\ I&P&L&Y&D \end{pmatrix} \]

@loke sorry, yes, I mean eigenvector

Clever #math pals, how easy is it to come up with an integer-valued 5x5 matrix with a given eigenvalue?

The Splitting Algorithm for Egyptian Fractions

Article by L. Beeckmans

In collection: Easily explained

The purpose of this paper is to answer a question raised by Stewart in 1964; we prove that the so-called splitting algorithm for Egyptian fractions based on the identity 1/x = 1/(x + 1) + 1/x(x + 1)...

<<In much of the country, the stereotype that boys do better than girls at math isn’t true – on average, they perform about the same, at least through eighth grade. But there’s a notable exception.

In school districts that are mostly rich, white and suburban, boys are much more likely to outperform girls in math, according to a new study from Stanford researchers, one of the most comprehensive looks at the gender gap in test scores at the school district level.>> https://www.nytimes.com/interactive/2018/06/13/upshot/boys-girls-math-reading-tests.html

@christianp Makes more sense when you realise that \(ab\) is a two digit number and not a • b.
