If you were looking for a clue about this year’s winner, you could perhaps have paid attention to the curious incident of my recent Mathoverflow question.
“But you haven’t asked any Mathoverflow questions recently.”
That was the curious incident.
Anyhow, it was wonderful to be told that Endre Szemerédi was to be this year’s winner. I won’t say any more in this post, but instead refer you to the Abel Prize website and to the written version of the talk I gave, which was intended for non-mathematicians.
