### The University of Leicester is going to sack its whole maths department (and rehire some of them)

The University of Leicester says it’s facing a big budget deficit, so it’s got to make some cuts. In the current British climate, that’s nothing unusual. However, the university has decided to cut a lot more from the maths department than elsewhere.

The way they’re going to do this is to sack almost everyone, then ask them to re-apply for slightly fewer jobs than there were before. Once it’s all done, 6 of the 21 mathematicians currently working at Leicester will be out of a job.

There’s some speculation that the reason that maths is going to be hit particularly hard is that it didn’t do particularly well in the last iterations of the REF and the National Student Survey.

The Universities and Colleges Union has started a petition against the cuts, disputing the size of the deficit and the need for so many job losses. They’ve written a response laying out their side of the story. The European Mathematical Society has also said it’s very concerned.

Tim Gowers has written a bit more about what he thinks is going on on his blog. As usual, there’s some good discussion in the comments as well.

### Do you use mixed fractions?

I’m at the MATRIX conference in Leeds, where I’ve just been talking to Adam Atkinson. He told me that he’s trying to compile a definitive list of countries that don’t use mixed fractions.

Here’s a mixed fraction: $2 \frac{2}{3}$
And here’s a non-mixed fraction: $\frac{8}{3}$
Actually, here’s an interesting fact about that number: $2 \sqrt{ \frac{2}{3} } = \sqrt{ 2 \frac{2}{3} }$
This only makes sense if you believe in mixed fractions (and unicode character U+2062, “invisible times”)

This is going to be one of those wipe-your-bum-standing-up situations: it’s entirely possible that you can be on either side of this divide and not know the other exists. Apparently, in some countries mixed fractions just don’t exist: an integer written next to a fraction is incorrect.

So, to help Adam on his way, I thought I’d start another in our long-running series of Aperiodical Surveys. Please tell us where you live, and if mixed fractions are OK in your book.

### Integer Sequence Reviews: A075771, A032799, A002717

It’s been almost two years since I last sat down with my friend David Cushing and did what God put us on this Earth to do: review integer sequences.

This week I lured David into my office with promises of tasty food and showed him some sequences I’d found. Thanks to (and also in spite of) my Windows 10 laptop, the whole thing was recorded for your enjoyment. Here it is:

I can only apologise for the terrible quality of the video – I was only planning on using it as a reminder when I did a write-up, but once we’d finished I decided to just upload it to YouTube and be done with it.

### New MathJax accessibility extensions provide collapsible expressions and maths-to-speech

MathJax, the web library that provides LaTeX-quality mathematical typesetting, has received a a new set of tools to improve accessibility of mathematical notation. The new MathJax Accessibility Extensions add on-the-fly speech rendering of notation, and a tool to explore expressions through intelligent collapsing and expanding of sub-expressions.

### Particularly mathematical Birthday Honours 2016

With the announcement the Queen’s Birthday Honours list, it’s time for the latest in our ongoing Honours-watch series of posts. In this, we search arbitrarily for ‘mathematics’ in the PDFs of the various lists, and hope our well-informed readers fill in the blanks where actual knowledge is required.

• Prof. Alice Rogers, Emeritus Professor of Mathematics, King’s College, London, appointed OBE for services to Mathematics Education and Higher Education.
• John Sidwell, volunteer, HMP Hewell appointed MBE for services to Prisoners through One to One Maths.
• Danielle George, vice-dean for teaching and learning, Faculty of Engineering and Physical Sciences, University of Manchester, appointed MBE for services to engineering through public engagement.
• Anthony Finkelstein, professor of software systems engineering, University College London and the Alan Turing Institute, for services to computer science and engineering.
• Economist Angus Deaton, professor, Princeton University, Nobel laureate, for services to research in economics and international affairs.
• Prof. Alan Thorpe, lately Director-General of the European Centre for Medium Range Weather Forecasts, appointed OBE for services to environmental science and research (thanks to Philip Browne on Twitter).
• Prof. Nalini Joshi was made an Officer of the Order of Australia (AO); the citation is more involved than the UK ones and reads “for distinguished service to mathematical science and tertiary education as an academic, author and researcher, to professional societies, and as a role model and mentor of young mathematicians” (added in an update 16/06/16).

It’s also worth mentioning the new batch of Regius professorships, 12 posts created at universities around the UK to celebrate the Queen’s 90th birthday: Oxford University has been given a professorship in maths, but no appointment has been made yet.
