Tim Gowers wrote in The Importance of Mathematics: If you were to work out what mathematical research has cost the world in the last 100 years, and then work out what the world has gained, in crude economic terms, then you would dis...

In view of the sustained interest in new polymath projects, Tim Gowers, Gil Kalai, and I have set up a new blog to propose, plan, and run these projects.  This blog is not intended to hold a “monopoly” on the polymath enterprise, bu...

This week I am in Bremen, where the 50th International Mathematical Olympiad is being held.  A number of former Olympians (Béla Bollobás, Tim Gowers, Laci Lovasz, Stas Smirnov, Jean-Christophe Yoccoz, and myself) were invited to giv...

As readers of this blog are no doubt aware, I (in conjunction with Tim Gowers and many others) have been working collaboratively on a mathematical project.  To do this, we have been jury-rigging together a wide variety of online too...

I’ve been watching, though not particularly intently, Tim Gowers’s attempt massively collaborative mathematics. I’m not sure if I’ve looked hard enough to judge, but it certainly looks as though it were quite successful. This of c...

From Tim Gowers’ blog comes the announcement that the Tricki - a wiki for various tricks and strategies for proving mathematical results - is now live.  (My own articles for the Tricki are also on this blog; also Ben Green has writt...

As most readers have probably learnt now, Tim Gowers’s “Tricki” is now accessible on the internet. In particular, my earlier article on Smoothing sums can be found there now, and consequently the older page I had will not be updated...

This is a continuation of several threads from Tim Gowers’ massively collaborative mathematics project, “A combinatorial approach to density Hales-Jewett“, which I discussed in my previous post. For any positive integer n, let be t...

My good friend Tim Gowers has just started an experimental “massively collaborative mathematical project” over at his blog.  The project is entitled “A combinatorial approach to density Hales-Jewett“, and the aim is to see if progre...

Is massively collaborative mathematics possible?, asks Tim Gowers....

A discussion of a blog post by Tim Gowers on the structure of mathematics.

A very enlightenning discussion at Tim Gowers’ blog.       

In lieu of commentary on incompatibility semantics today, here are a couple of worthwhile links. The first is a tutorial on how to use Zorn's lemma by Tim Gowers. It is quite good and has several examples.The second is a short piece...

I’ve got internet access again, but I’m busy with a few things today, like assembling my furniture. Luckily, Tim Gowers has a post on “How to use Zorn’s lemma”. His example is the construction of additive (not linear) functions fr...
