Words aren't like shit. Shit happens. Words don't just happen. You have to make them happen.
Or maybe I'm just verbally constipated.
Moving on to other matters, it looks like the Iranians have elected an engineer with a doctorate in traffic & transport to be their next president. Mahmoud Ahmadinejad also happens to have been the mayor of Teheran for the past two years, and implemented conservative policies like requiring male city employees to have beards and long sleeves. (Well, that's fair enough. If women must wear clothing that covers everything, so must men...) Seriously, the Iranian bloggers are upset, and I get the sense that this is a situation where the Ayatollah & other clerics keep an eye out for electable citizens pliable to their views and bring them to office - and that Ahmadinejad is one such citizen. Oh well, the Khatami backlash is here.
There's been a lot of discussion here, thanks to some comments by Matthias during Junming's talk, about whether the graph normalized Laplacian (the D.^(-1/2)*L*D^(-1/2) version) approximates the continuous Laplacian. It didnt seem to, but when Denny and I talked about it later, I observed that a proof might be possible, since, in the limit, nearby vertices - on which derivatives are computed - would have the same degree as they approximated the probability measure at the corresponding point. I'll find out when Denny gets back on Monday if he got this 'proof' passed Matthias. It's not rigorous, of course, but before that we had agreed with M's assertion that this normalized Laplacian was only an analog, not an approximation, to the continuous-case Laplacian on a manifold.
Didn't do much today so far. My sleep schedule is, to put it politely, shot to little eensy-teensy-weensy schmidtereens. Got up at 5. If that sounds normal to you, bear in mind that it's now the middle of my day, and it's the middle of the night. Ich mochte ein bier.

Of course words happen...just open a dictionary. A meaningful sentence on the other hand may be a bit tricky for some. But words, they happen.
