Jason Ermer’s Collaborative Mathematics project has launched its first video challenge. The project aims to allow mathematics to happen collaboratively via the medium of online videos, and video responses. The idea is that having watched the challenge video, you work with a group of friends (collaboratively) and post a response video, and then watch others’ response…
Your help needed: survey of international mathematical cultures

Now a comment on a discussion about enabling MathML in Chromium, the open source web browser project from which Google Chrome draws its source code, has announced that this feature will be turned off, for now. The…
More experimental evidence for the infinitude of the primes
In a classic example of the intersection between maths and news, there’s been a new Mersenne prime discovered! Mersenne primes are numbers of the form $2^p – 1$, where $p$ is a prime number. They’re highly valued as a source of large prime numbers, since testing the primality of a (suspected) prime of this form…
