Does !TeX => bad maths?

Whilst browsing the writeLaTeX twitter feed the other day, I came across an interesting observation that the absence of TeX is a good indicator that a math paper has issues, highlighted by John Cook (@TeXtip) in this tweet:

In the original blog post on this (entitled ‘Ten Signs a Claimed Mathematical Breakthrough is Wrong’), this is only one of a number of points made, although it is the first, and is accompanied by the interesting statistic that:

“This simple test (suggested by Dave Bacon) already catches at least 60% of wrong mathematical breakthroughs.”

My first set of WriteLaTeX how-to videos

London is certainly keeping me busy, so it’s a very short post today simply to help disseminate the three ‘how-to’ videos I’ve recently produced for writeLaTeX:


If you’re using writeLaTeX and have any feedback, please let me know (@DrHammersley).

Google Docs for Science – a short introduction to WriteLaTeX


Most of the world’s technological and medical innovations began with a scientific paper — there are now over two million scientific papers published every year, and many more technical reports and presentations. As scientists, we spend a lot of time writing, reviewing and publishing these papers, and whilst the Internet has drastically improved how they’re published and distributed, writing (and collaborating) is still difficult. With WriteLaTeX we’re helping to change that.

WriteLaTeX is a real-time collaborative writing platform which lets you create, edit & share your scientific ideas easily online using LaTeX, a powerful tool for scientific publishing. My co-founder John Lees-Miller created writeLaTeX to address the problems we experienced ourselves when writing papers collaboratively, in particular in the fields of mathematics, physics and computer science. We both have backgrounds in mathematics so naturally used LaTeX but when working with co-authors in different countries and different disciplines, there was no easy solution – so John created one!

The History of Computing evening at Google London

This evening we were fortunate enough (thanks to BGV) to have been invited to a discussion celebrating the history of computing, held at the main Google offices in London.

All the talks and videos were very interesting, but the one that caught my attention in particular was a look back at how Lyons the bakers were one of the first companies to implement what today we’d call a management information system.

All in all, a very inspiring way to kick off our stay in London!

Ultra PRT Pod model at Nesta

First day in the office, and a familiar looking Pod is on display!

This is a scale model of a Heathrow Pod, the driverless taxi system I worked on for five years before founding writeLaTeX. There are twenty one of these running at Heathrow Airport, as part of the world’s first commercial PRT system — check them out if you’re ever at T5!
