Here in Williamstown we got just about a foot of snow.
When I was at the Field’s Institute in Toronto on sabbatical in the fall of 2010, I played duplicate bridge with 25 different partners. Here’s an interesting hand from Hazel’s Bridge Club on September 6, with Joyce Fraser. I was East at 4S. Do you see how to make it? The key after taking the heart ace is to force an entry to dummy by leading a low spade to the 6. This was good for 10/15 matchpoints.
Actually it can be set by perfect defense. Do you see how? South has to underlead the AK of clubs to North’s Q, so that North can return a diamond to eventually score two diamond tricks.
Here’s an interesting hand from a Royal Caribbean regional bridge tournament cruise (with 6000 passengers and 2000 staff on the Allure of the Seas) with Larry Cohen in December, 2012. After my partner (Lois Hausman) opened 1D, I took her to 6N. After a heart lead, she properly advanced the 9 of spades and West properly covered, leaving East with the J86 after dummy’s A1075. Do you see how to make the hand? Take the club finesse and the AK, play out the red winners, and then put East in with the club 9 to his 10. Now he must lead from his spades.

After the week-long soap bubble conference in Scotland, I spent the rest of spring break in my hometown, visiting my mom and enjoying the arrival of spring, exemplified by the pink blossoms of the cherry trees. We attended a fundraising dinner by the new Allentown School District Foundation, with excerpts from school spring musicals. They sponsor all kinds of creative programming in the schools. Their greatest current need is funding for a director.
It’s always hard to leave. On the way back to Williams I wrote the following poem:

On the occasion of its centennial, the Royal Spanish Math Society has published a commemorative issue of their Revista. Mathematicians describe some early influential encounters with mathematics.
The proof of the regularity of an area-minimizing surface with a given smooth boundary has had a long and interesting history. Following work of Douglas, Rado, and Osserman, Gulliver [1973, G] proved that a least-area map of a disc into R3 with prescribed boundary is a smooth immersion on the interior. The map need not be an embedding and cannot be if the boundary curve is knotted. The possibility of boundary branch points remains open today.

I have heard that the NSF is considering changing the name of the Division of Mathematical Sciences to the Division of Mathematical and Statistical Sciences.
