Nobody tells you about the emotional part of leaving grad school. The time I've spent here has been longer than the time I've spent anywhere outside of the town I grew up in. I've developed relationships here that will (I hope) last me a lifetime. I have become a wife here, an adopted "auntie", and a teacher to many. As I bike into my apartment complex, I wave left and right at familiar faces. I see children who were babies when I started grad school here. I stop to talk with former students who are themselves moving on to grad school, new jobs, teach for america, or travel abroad. Getting ready to go isn't just about writing my thesis -- it's about saying goodbye to the people and places I've bonded with.
Granted, I'm happy right now to be finishing the umpteenth grade and to be starting a new chapter in my life. But I'm just warning you -- steel yourself against the fact that you will be processing a lot more than just your mathematics as you write up that thesis. You'll be thinking about what to keep and what to toss, you'll be spending time with friends, reconnecting with those you've lost touch with, visiting with those who are just near enough to drive to see and just far enough to not bump into. You'll be wondering if anyone else will carry on the traditions you've started. You'll see your surroundings with different eyes. Try it now...It might be an interesting exercise.

This week Dai Fujiwara, a fashion designer, presented a collection based on Topology, specifically Fujiwara discussed his collection with Professor Bill Thurston, who is famous for his Geometrization Conjecture . Here is a blog entry with pictures that discusses the role of geometry in this years fashion. Another designer is also mentioned as incorporating geometric ideas in the NY Times. Also see the YouTube interview of Thurston and Fujiwara .

With the 2010 Census about to take place in the middle of this month during what is Spring Break for many college students, we might start to think about fairness. As people receive so much junk mail, it's important to convey the importance of filling out the ten questions (which is the fewest number to ever appear on a census). According to the Census2010 website $400 BILLION is distributed according to the numbers recorded in the census. Just recently, a house committee decided to table a proposal for a bipartisan commission to help decide the redistricting that will occur when the census is over. So how will redistricting be decided fairly by those people who have themselves benefitted from possibly unfairly drawn districts?
Here we see the 12th congressional district that was approved in 1994, and which was controversial for being racially "gerry-mandered" . Now, we have to ask ourselves if there is anything wrong with a district having an "bizarre" shape, whether this is somehow giving an unfair advantage. Perhaps requiring that districts be "sensibly shaped" in some way is a reasonable way to ensure fairness. Perhaps not.
Let's also take into consideration that "There's nothing Maryland can do about its bizarre shape," as economist Christopher Chambers said at the AAAS symposium on Fairness and Mathematics. Professor Chambers is one of the authors of an academic article entitled "A Measure of Bizarreness" that will soon be published in the Quarterly Journal of Political Science. So however we may choose to answer the question of "How Bizarre is that shape?" it must take into consideration that the shape may already live in a somewhat bizarre larger one. The way to measure this according the the authors is to use a path-based measure of convexity. Given a district, its bizarreness is determined by the probability that it contains the shortest path within the state that joins two randomly selected points in the district. The higher the probability, the lower the bizarreness.
Here's a January article from Slate magazine concerning this matter.
