The feeds at Mathblogging.org ran dry this morning following a realisation that every topic has now been covered.

The news prompted a major fall in the Mathblogging.org share price, sparking concerns about the aggregator’s future.

The news is particularly unwelcome for The Aperiodical, a blogging collaboration which is still yet to formally launch. The realisation came to light when the team behind The Aperiodical concluded that there was nothing new to blog about.

“We thought we could write a post about representing Sicherman dice as a different dissections of a diagram,” said Katie Steckles on behalf of the group, “but it’s been done”.

The team then thought they might write about the asymptotic distribution of a single eigenvalue gap of a Wigner matrix, a description of Nicolas Bourbaki’s wedding invitation or a story about a US President finding an original proof of the Pythagorean Theorem, but all have been written.

“We worked all through the night trying to think of ideas,” Steckles explained, “but came up blank. Every possible topic has been blogged somewhere, and there’s certainly no point in mathematics blogs repeating each other.”

So what now for the group? “We’ll just have to wait until someone invents some new mathematics.”

Until then, all mathematical blogging worldwide will cease and mathematical bloggers will have to find some other contribution to make. Some have announced plans to move down the xkcd purity scale until they find a subject that can be infinitely re-interpreted.
