Dark days for MathML support in browsers

For a brief moment at the start of the year, Google’s Chrome browser could render mathematical notation written in MathML. Since then, things have got worse for mathematics on the web.

In February, the MathML rendering code was removed by Google, citing concerns about security and code quality. Now, a member of the Chromium team has announced that Google will not be supporting MathML in the foreseeable future:

MathML is not something that we want at this time. We believe the needs of MathML can be sufficiently met by libraries like MathJax and doesn’t need to be more directly supported by the platform. In areas where libraries like MathJax are not good enough, we’d love to hear feedback about what APIs we would need to expose so that MathJax, et al, can create an awesome MathML implementation.

Peter Krautzberger, manager of the MathJax project, is not happy.

Happy Birthday Euler!

Today is Euler’s $-306 \times e^{i \pi}$th birthday, and Google have chosen to celebrate (despite ignoring several other prominent mathematical birthdays, including Erdős’s centenary – see the @MathsHistory twitter feed for a full list) by creating a Google doodle on their homepage.

For anyone who isn’t aware, this is when Google changes the image above the search box on the homepage at Google.com, so it still says ‘Google’ but using an appropriate image, which sometimes has built-in interactive elements. I thought it was worth pointing out some of the fantastic maths they’ve included in today’s doodle.

Recreational Maths Seminar this Sunday at 7pm GMT

There was no Recreational Maths Seminar last Sunday because I had a confluence of work, family stuff and overknackeredness from MathsJam the week before. The coming weekend should be considerably less busy, so let’s have our second seminar this Sunday, the second of December, at 7pm GMT. That’s 2pm EST (New York), 11am PST(California) and 6am EDT (Eastern Australia, on the 3rd of December).

Recreational Maths Seminar – Picture-hanging puzzles

I hosted the first (proper) Aperiodical recreational maths seminar yesterday. We discussed the paper Picture-hanging puzzles, by Demaine et al. Click through to watch the YouTube recording of the session.

A recreational maths seminar?

Would you be interested in taking part in a sort of online video-chat seminar about recreational maths? Then read on!

Follow Friday

I’m hijacking Katie’s newly-instituted series of posts about who to follow on Twitter with a post about who to follow on Google+.

Google+ famously has almost nobody on it. If anyone knows the potential for really interesting exceptions to the word “almost”, it’s mathematicians, so by that mad logic there should be some really interesting mathematicians on Google+. As luck has it, there are! It seems that the unconstrained nature of Google+ posts gives mathematicians the space they need to express themselves usefully.

Here are a few mathsy people you might like to encircle on Google+.
