They just posted the results here and I did about how I expected, 19th place. I'll post more on the final results of the competition later but just wanted to throw this up there. Thanks for all the support, and thanks IB for doing this thing. I hope that check is in the mail!

Tesla Coils Instead of Speakers
Last night I saw this concert performed here on the UIUC campus. Two Tesla coils were set up and connected to a continuous note keyboard called a continuum. The Tesla coil on the left was filtered for higher frequency signal while the coil on the left was filtered for lower frequency signals that came from the continuum keyboard. The Tesla coils then generated these lightening bolts at the frequency of the electronic signal generated by the continuum keyboard so that the net result was lightening that created the sound of and was synced to the music. Essentially, these two Tesla coils replaced speakers. As air becomes ionized in a lightening strike it heats and expands rapidly, this pressure disturbance leads to the sound of thunder. If you could control the pitch of that sound with an electrical signal then you could play music with lightening, and thats exactly what they did last night. It was pretty wicked, like something from the distant future. Here's a picture of the musician before he started playing the continuum:

If you liked that video, I found another one on youtube from a show they put on without the continuum keyboard. It has some more recognizable tunes in it. Click here to check that one out.

Sharks Are Pissed
"Because the global population of humans is growing fast, so more people go to the beach, said George Burgess, curator of the International Shark Attack File at the Florida Museum of Natural History. And nowadays, beach-goers don't just go for a dunk. They hang out in shallow water (home for many sharks) for long periods of time to surf, windsurf, boogie-board, kayak and dive.
The number of worldwide shark attacks overall increased from 63 in 2006 to 71 in 2007, continuing a gradual upswing over the past four years, Burgess said.
Sharks are disappearing from the world's oceans due to overfishing, says Julia Baum, a researcher at the Scripps Institute of Oceanography in San Diego. Baum and some of her shark-tracking colleagues made comments to reporters earlier this month at the annual meeting of the American Association for the Advancement of Science in Boston
Being scared of sharks is really laughable for anyone who gets around in an automobile. There are around 70 shark attacks worldwide but how does that compare with car accidents? There are an estimated 1.2 million car accidents worldwide each year leading to roughly 3000 dead per day, versus one death by shark per year. In fact, its very likely you'll live if you happen to be one of the 70 poor souls who gets bitten:
"Your odds of living are greater than 90 percent. The rate of shark-attack fatalities hit an all-time low in 2007 for the past 20 years, Burgess said. In fact, the trend for shark-bite fatalities in the 20th century is "down, down, down, decade by decade," Burgess said...
So I can understand why the sharks might be oh, just a little bit upset. I personally love sharks, love to swim with them. In fact the pictures in this post were taken by yours truly last summer. If you want to see some really amazing interactions between sharks and humans check out my post on tonic immobility.
