You, a tech startup with millions in angel finance: made an app to turn handwritten maths into TeX.

Me, just the worst kind of smart alec: convinced a pen #plotter to turn TeX into handwritten maths

I've made a new game, about holding hands.

The hard part: some of these fellas have lots of hands!

A quick round-up of three recent Wikipedia Good Articles:

Factorial, https://en.wikipedia.org/wiki/Factorial – you know, \(n!\).

Jessen's icosahedron, https://en.wikipedia.org/wiki/Jessen%27s_icosahedron – polyhedron with all-right dihedrals despite not having axis-parallel sides; the shape of the "Skwish" tensegrity

Erdős–Straus conjecture, https://en.wikipedia.org/wiki/Erd%C5%91s%E2%80%93Straus_conjecture – the question of whether \(\frac{4}{n}=\frac{1}{x}+\frac{1}{y}+\frac{1}{z}\) has positive integer solutions for all \(n>1\)

The term `angle' in the international system of units

Article by Michael P. Krystek

In collections: History, Notation and conventions

The concept of an angle is one that often causes difficulties in metrology. These are partly caused by a confusing mixture of several mathematical terms, partly by real mathematical difficulties and finally by imprecise terminology. The purpose of this publication is to...

This is awesome!

@christianp I notice you are now square, triangular, and Kryptonic.

Have a good one.

Dreary work toot alert!

I've written a Python script to synchronise a folder on your PC with a Canvas LMS course's files section.

I was inspired to make a computery version. I've called it "This island is big enough for the both of us"

Word calculus in the fundamental group of the Menger curve

Article by Hanspeter Fischer and Andreas Zastrow

In collections: Combinatorics, Fun maths facts, Games to play with friends, The groups group

The fundamental group of the Menger universal curve is uncountable and not free, although all of its finitely generated subgroups are free. It contains an isomorphic copy of the fundamental group of every...

The Fastest and Shortest Algorithm for All Well-Defined Problems

Article by Hutter, Marcus

In collections: Attention-grabbing titles, Basically computer science

An algorithm M is described that solves any well-defined problem p as quickly as the fastest algorithm computing a solution to p, save for a factor of 5 and low-order additive terms. M optimally distributes resources between the execution of...
