I went to the Olympic Park for the first time today. It hasn’t been open to the general public for very long, and indeed a lot of it is still closed, and it is quite hard to find out how … Continue reading →

I’d like to thank the University of Toronto mathematics department (my doctoral alma mater) for the nice news item on its front page mentioning my ICM invitation. (It was posted a while ago, but I only saw it now.) Being … Continue reading →
