This from Ming:

I found this paper in the current issue of IPL. It was quite an enjoyable
read. It discusses the undecidability of a Tetris-related problem; the
reduction is from, guess what, the Post correspondence problem.

Cheers,
Ming

You can find this paper on our resources page.  Follow the Tetris link.

This came from Vijay.  Thanks, Vijay.

The Clay institute problem that supposedly has been
solved is Poincaré’s conjecture and below are the 2
links to the preprints of the papers (they are well
beyond my scope to understand)

http://www.arxiv.org/abs/math.DG/0303109

Both are by Perelman.

We plan to hold the class in room EPS 348 rather than the room listed on the schedule of classes.  This should be more convenient for everyone.
