First, some extradiegetic comments. I did not post much last year. The main reason is obvious – for the first half of the year, I was very busy finishing the proof of the ternary Goldbach conjecture; then, during the summer, I had many speaking engagements – and I also spent a non-trivial amount of time writing a popular account of the proof for this blog. I spent the October-December rewriting the second, longer half of the proof – so that the proof is now in three papers, each of them a little over 70 pages in length. (I was also looking for new topics, doing some more travelling and lecturing, and retaking Russian and Classical Greek, among other things.)

At the same time, even though I had many reasons for staying away for blogging, it is a bit of a pity that I did not have time to blog precisely at a time when there started to be many more potential readers for it. Of course, some of them (you) are probably still around.

So far, I have written here mostly on mathematics, cinema and my travels. I would also like to touch a bit more frequently on a few serious subjects, not strictly mathematical, though sometimes related to mathematics and academia.
