A few years ago, the Science Channel aired an episode of SciFi Science, “How to Build a Lightsaber” hosted by theoretical physicist Dr. Michio Kaku. He explained some theories that might be used and developed a rough design that should be “workable in our lifetimes.” Of course almost all of his episodes end up with that qualification. Last month it looks like there was a breakthrough in the hardest part of making a lightsaber work, getting the blade to stop at a certain point.
Although the most prominent uses for controlling the depth of laser cutting are surgical and clinical, Fraser said the team is “very excited about the potential industrial applications,” especially since compared to clinics it’s easier to get new technology into industries.
Unfortunately, the goal is to make the lasers useful surgery, not chopping off alien arms at cantinas.
I recently ran across this interesting video during one of my many sessions with StumbleUpon. The video via GeeksAreSexy (shown after the “more”) demonstrates a guy in a robotic exoskeleton performing a variety of tasks to demonstrate the strength of the device. This was a weird coincidence because I was in the process of reading Starship Troopers by Robert A. Heinlein. His Mobile Infantry armor was much more elaborate, but I’m always interested when things from science fiction start to become science fact. (more…)
I just ran across possibly the most awesome Star Wars item ever. Nikko America has a special edition remote controlR2-D2 home theater audio/video projector that does just about everything. It has a ton of features, including being able to project on the ceiling (not sure I’d ever use that), official sounds, and a ton of inputs including an iPod dock. The tech specs are pretty good, but I’m sure you can build your own home theater that is better with less than the $2900 price tag. It won’t have the massive geek factor that R2-D2 has though. Be sure to check out the video to see it in action.
For all of you geeks that have had your head in the sand, artificial intelligence has hit a milestone. Yesterday, IBM’s Watson trounced these bags of meat known as Ken Jennings and Brad Rutter in Jeopardy. If I ruined the result of the match, I apologize, but I figure posting a day after is enough notice for anyone that was following this from the start. For some more background on Watson and behind the scenes info, check out my original post on this. I have to admit that I was rooting for Watson from the start. I was a bit worried when after the first day in the tournament Watson was only tied for first place. I’m not sure what happened between the first and second matches, but Watson rocketed ahead in the second day and never looked back.
I think IBM might have been in a rush to show off their new creation. It was interesting to see the answer confidence levels during the rounds, often revealing some really wacky possible answers. Watson crashed several times during the second day of filming, nothing a regular viewer would notice while watching the recorded match on TV. One criticism I’ve heard about the match was that Watson was fed the questions electronically rather than relying on voice and character recognition. I have to agree that the electronic delivery could have been an advantage. Had voice recognition and OCR functionality been used in Watson, the victory would be quite a bit more impressive. I could clearly see the two mere mortals struggling to buzz in and shake in frustration when Watson was faster. The producers touted the physical buzzer plunger that Watson had to activate, but I still think that Watson had the advantage.
I would be interested to see a rematch in a year but with only inputs into Watson be voice and video of the Jeopardy board. After all, Deep Blue was given a second chance versus Garry Kasparov, so why not give the humans a second chance on more equal footing? It is quite possible that programming algorithms over the year would improve enough so that Watson still would win, despite the reliance of voice recognition and OCR. In that case, the victory would mean that much more. Even if you know the outcome already, I still recommend watching the matches. I already saw the Nova special, so I skipped through most of the background stuff from the IBM folks. Here is a link to my YouTube playlist that has the three episodes broken into 6 videos. Check it out! Then you can tell your grandchildren how you watched a computer beat humans in Jeopardy for the first time. Then they’ll ask, “Humans were allowed to play Jeopardy back then?”
