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 just ran across a cool video of a flying robot playing Jingle Bells on an electric piano. The tempo seemed a bit off, so I clicked through to YouTube to see if there were any more videos. A link for how it works popped up, so naturally I clicked it. Base off of the video, it looks like a human was controlling the robot, so not as impressive as I initially thought. They show some background on “co-pilot” routines that assist the human controllers to keep them from making mistakes. I find this interesting because eventually with AI, these little machines could be completely automated. This reminds me of the creepy surveillance robots from Dark Angel. With special routines to keep these from bumping into obstacles, I can definitely see them flying around our cities sometime in the near future. If you want to see the Jingle Bells video, click through the via link at the bottom. I found this video more interesting though.
Tonight with my wife, I watched an interesting episode of Nova titled “The World’s Smartest Machine.” Romantic, right? You can tell we are a couple of geeks at heart. Being a huge fan of Asimov and his robot creations, I am continually amazed at the progress of robotics and artificial intelligence. As a kid I was playing chess as early as the 3rd grade. I’ve always thought of myself as a pretty good chess player. When I heard about a computer that supposedly could beat a world champion chess player, I was intrigued. Garry Kasparov battled IBM’s Deep Blue supercomputer in 1996 and won, however he eventually lost a rematch in 1997. Well, IBM is back at it, this time taking on Jeopardy. Nova takes us behind the scenes with the developers of “Watson,” the next step in AI. I was disappointed when the episode ended and it didn’t say who won. I didn’t realize until logging on PBS.org that the contest actually was taking place while I was watching Nova (on my media center PC). After some frantic Google searches, I eventually came across a Twitter feed with a link to a Youtube posting of the episode. This was not quite 2 hours after the episode aired! Isn’t technology great? I expect the Youtube post to be served a DMCA take down, so watch it soon if you plan on it. In addition to the episode at the end of this post, I’ve embedded the Nova preview and an humorous parody of the challenges Watson overcame during his development. I suggest watching the Nova episode first. If you are at all interested in AI, you must check these out!
There are two more nights to the match, airing Tuesday February 15th, and Wednesday the 16th. Be sure to check them out, along with some live blogging on PBS.org. I find myself rooting for Watson, not because I want to see humans defeated, but because I want to see humans capable of making something smart enough to do it. Who do you think will win? Who do you want to win?
It’s been quite a while since I’ve read Dune. I found my way to this interesting conceptualization, Sietch Nevada, through my regular StumbleUpon clicking. For those not familiar with Dune by Frank Herbert, please check it out! It is an excellent novel, as described in my review. I find it interesting how many ideas are drawn from Sci-Fi. Everyday technology like cell phones, video conferencing, and robots (well maybe not everyday yet), were hinted to by authors long before they were developed. I find the Sietch concept intriguing because I lived in Phoenix, AZ for many years. A few years after I left, I started hearing about how Lake Powell, fed by the Colorado River, might dry up soon. I thought that it meant there would be no more water, but experts are referring to “dry” as unable to generate hydroelectric power. So, not only will water levels be low, but there could be power shortages as well!
