I am no longer regularly updating this blog. Instead, I am placing all of my work and blog posts on my personal website at http://wcm1.web.rice.edu.
If you have been reading this blog by subscription in a feed reader, please subscribe instead to my new RSS feed. You may also want to check out two posts on the new site that you may have missed, one on two simple timers, and one containing my recent lecture on Dick Dowling and Sabine Pass: The View from Emancipation Park.
I will be leaving this website and all of its posts here in order to maintain the permanence of URLs. However, I have also cross-posted the essays here on my new site, with the exception of the first post introducing this blog.
