It has been a little quiet around here, mostly because I was staying at home in Germany (admittedly not a good excuse in the days of almost universal WiFi internet access). I wasn't completely lazy, however. And there is a pile of half-finished blog-posts waiting to appear.
Meanwhile, please help me welcome Sujit Datta to the physics blogosphere. Sujit is a Master's student at the University of Pennsylvania who researches quantum transport in carbon nanotubes and is especially interested in condensed matter physics and the study of complex systems. He started his blog on January 1, 2007, and so far has been a very prolific poster of interesting articles.
