Remember at the end of The Empire Strikes Back where Luke gets his hand chopped off by Vader? During one of the closing scenes, a robot doctor finishes up installing a replacement hand for Luke.
Luke Skywalker's Cyborg Hand
Kevin Warwick did something similar as an experiment, but without the whole getting his hand chopped off step. Instead he put an electrode in his hand that could transmit commands to a robotic hand through radio waves. This was done back in 2002, and somehow I never heard of it. I’m sure Ray Kurzweil would be proud. Check out the video below for more information about how he did this, and some other advances like using rat brain cells to power robots. If you are at all interested in robotics, cyborgs, or AI, you’ll be in for a treat.
I wasn’t really expecting much when I heard about Surrogates, so waited to watch it until it came out on DVD. From the previews it looked like many other science fiction action films that seem to be pumped out by Hollywood. The main premise of the movie is that humans live their lives through “surrogate” (robot) bodies. I’m a huge fan of Asimov and his robot novels, so this was enough to catch my attention. The human interface is kind of like how control worked in Avatar, but instead of an organic body as the host, it is robotic. I would definitely not classify the surrogates as the cyborgs that Ray Kurzweil thinks we will eventually become. One of the main advantages to using a surrogate is that the owner is always protected, so in some ways they are better than cyborgs. There was no way for any harm to come to a user, until now.
Tom Greer, played by Bruce Willis, is in charge of investigating the destruction of a couple of surrogates. This is usually not that big of a deal, but one of the owners is found dead. Whoever wrote the script really wasn’t trying anything new as far as the murder/mystery approach is concerned. I was expecting a lot more action based on the previews that I saw. It felt like I was watching for 40 minutes before things started to get moving. This move was all around average in most respects. Nothing really stood out. It wasn’t bad, but not great.
One completely unrelated observation is that I found Bruce Willis’ upper lip (stash zone) alarmingly long. It looked almost twice the size I’d normally expect. I think of most of the roles I’ve seen him in, he’s got a beard of some sort, so that kind of hides that feature of his face. Am I alone here? Check out the pic on IMDB
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?”
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.
