I am … unhindered by talent

Lacking the time or neural function to generate any new content, I’ll instead pretend to be engaging in some sort of hip new mash-up by dropping two wildly different videos on you. Connections? Nope. Cool synthesis that comments on the post-modern state? Doubt it. Worth the time? Probably.

The first is a really fine piece of election season film making (thank to Pharyngula for the tip):

Favorite quotes: Cheney reminding us that “Some people lie” (speaking from experience there?) and Pat Buchanan saying that McCain will “make Cheney look like Gandhi”. Wow - that’s something I really don’t want to see.

Then, after you’ve found the tissue box or finished smashing the crap out of the couch cushion in anger and frustration, you can lighten up with this bit of silliness courtesy of Joe R.:

I think it’s arguably a bit long (they felt like they had to get the whole lecture into one song), and watching the “dancers” gets a bit painful in places. Still, it’s well written and fun, and I like the chorus. It’s cool to see people trying different ways of getting the word out and, for better or worse, I suspect that more people will learn a little physics from this sort of thing than from “normal” sources. There are 34,925 people following the Mars Phoenix lander on Twitter, and over 4,000 (as of today) following CERN. Hopefully all this is a cool sign for the future of a populace engaged in science!

And this sort of stuff really makes certain academics nervous — they worry that somehow the only way they’ll keep their job is to do this kind of thing in class — and that’s gotta be worth something.

Hmmm… Applying vaunted American know-how to find new solutions to the problem of energy independence? What an odd, odd thought, especially when McCain supports a tiny, slow band-aid that … well … won’t really help at all.

We were in Fargo a few days ago buying a car. We sold our one and only car when we went abroad, and are currently on borrowed wheels. There was serious discussion of not even getting a car, or perhaps leasing a car for the winter months while going without a petrol powered vehicle in the summer when we can bike around town. In the end, though, we decided to go ahead and buy a shiny blue Honda Fit. (This is the second time we’ve bought the exact same car as my sister a year or two after she bought hers. We’re not very original, I’m afraid. That, and my sister rocks!)

The Honda dealer said that the demand for Civics, hybrids, and Fits has been really high, and they’ve had periods where they haven’t had any Civics to show people, including used ones! (And this is North Dakota, where I suspect trucks have long out-numbered compacts.) Given that most people won’t keep a car for all of the 7 years it will be before we see any of the off-shore oil from McCain’s proposal, Obama’s plan seems to be much more in touch with the mood of the populace.

What I’d really like is for the U.S. people (and government) to realize that there’s real value in basic scientific research, and understand that kind of research is going to have to be an important part of any solution to the current energy and climate problems.

While in Fargo we also bought Sub-Evil a new bike, and will probably buy a new bike for WeatherGirl in the next week or two. This, combined with the fact that mine is getting a substantial tune-up at the moment, means we’ll all be on two spiffy wheels as much as possible, at least when the weather allows.

I don’t have time to come up with a clever April Fool’s joke, but I will take a moment to point everyone at the classic 1957 BBC program on the spring spaghetti harvest in Switzerland.

Really wonderful stuff, and very cool that the wonders of the intarweb (and the sensibleness of those nerds at the BBC) allow us to see it all over again!

Wow - this is quite amazing. About mid-way through Big Dog (a defense project from Boston Dynamics) slips on some glaze ice and recovers without actually falling down, which involves some super cool real-time responses. The video is long-ish, but definitely worth the investment.

I’d love to know what the burn out rate for the joints and motors are. One of the amazing things about biological organisms is that we can balance muscles against each other to hold a position without wearing ourselves out. Many walking robots, on the other hand, end up exerting so much force in simply maintaining their position that they tend to burn out key components really quickly. Given the responses and forces involved in Big Dog’s movement and balance, you’d think they’d have this problem in spades. If these trials go on for any length of time, however, they presumably managed to handle this to some degree. Their web site says “BigDog’s legs are articulated like an animal’s, and have compliant elements that absorb shock and recycle energy from one step to the next.”; the idea of recycling energy back into the motion (use it instead of fight it) certainly looks promising.

The research is being funded by DoD money, with the hope that robots like this could help carry material in the field. I could imagine nice civilian applications, however. An infirm person in Morris, for example, might be capable of walking to the grocery store, but not capable of carrying a shopping load home. A smaller, electric version of this could be a nice alternative to cars in that situation.

Thanks to Sub-Evil for the pointer!

Much chops to Bad Science for pointing out Phun, a simulation environment/game/construction engine thingie that (judging from the videos) is just super fun (ho, ho, ho) to fiddle with. It seems a wonderfully open-ended platform for making stuff, which is of course the great strength of a pad and paper, or a bucket of Legos. This demo video gives a sense of the range of possibilities:

There’s a YouTube group devoted to this thing, and the number and variety of little clips there also speaks well to the Phun’s flexibility. We even have one person building a binary adder, and another a working pinball machine. Very, very cool.

The sad, sniffle, miserable bit is that Phun doesn’t run on Macs at the moment. It supports for Linux and Windows, though, and there are people working on a Mac port, so my fingers are crossed. It just seems like it would be too damn much fun to play with.

You all know I stay up late at night worrying about possible career opportunities for Our Fearless Leader upon his impending retirement from the Oval Office next year. Given his broad-minded and impeccable taste and his keen intellect, I’d rather fancied him as a gallery director, maybe for something like MoMA, which would benefit from both his gravitas and sense for the cutting-edge.

This video, however, pretty much scuppers that plan. Never good to be caught making up completely fictional and inaccurate provenance for a painting, especially one that has pride of place in that most public of home offices.

I’ll obviously have to get my thinking cap out and consider the matter further. Ideas?

Is it just me, or is this a desparately classic case of old folks (i.e., people my age) just not realizing that the world has moved on a wee bit?

The University of Minnesota Office of Information Technology is proud to announce that the University of Minnesota is soon to become a member of ResearchChannel. ResearchChannel was founded by a consortium of leading research and academic institutions to share the valuable work of their researchers with the public through a cable television distribution network. ResearchChannel is now available to more than 30 million U.S. satellite and cable television subscribers and more than 1.6 million people who visit the ResearchChannel Web site at http://www.researchchannel.com each year. The channel also is available on 70 university and school-based cable systems in the United States…

Cable TV was cool when I was college age a zillion years ago (back in the 80’s), and we thought MTV was pretty darn cool.

That was then, though, and now is different. Sub-Evil’s generation don’t channel surf through the cable offerings, amazed that they have more than 4 options. They just don’t watch TV like we did. They time shift like mad, and cruise through a vastness of on-line offerings that make those early cable days seem positivity puny by comparison.

And now the U decides to get excited and pipe its research out to students on a cable television distribution network?!?

Uh, sorry, but I have my doubts. 30 million U.S. satellite and cable television subscribers?

Ooh.

Ahh.

Yawn.

In fairness, however, they do almost address this, even if in the tone of an afterthought:

…and was recently launched on iTunes U and YouTube.

w00t! YouTube! They get it!

Well, sort of.

You see, a quick look suggests that what they’re providing is honking great collection of lectures. They’re almost all long (mostly on the order of an hour, some closer to two), and seem to be largely academic “talking head” videos. Just what a college student wants to unwind with after a long day of…um…lectures.

Thus it’s hardly surprising that ResearchChannel’s most viewed video on YouTube has only been viewed (as of 2 Mar 08) 1,592 times, and their 10th most viewed has only been viewed 153 times (so a very steep drop in views). For comparison, the video of Sub-Evil’s performance of “Taco Man” at the ASA Talent Show 1.5 years ago has been viewed 1,033 times. It’s 1.5 minutes long, was shot will a cell phone from the audience, and only shows the second half of the song. But it would place a solid fifth in view count amongst the 166 videos that ResearchChannel has on Youtube. To be fair, it doesn’t look like any of the ResearchChannel videos has been up for much more than a month. Sadly, though, I suspect that the fragmentary “Taco Man” video will continue to hold its own against most of these even if we check back in a year or two, even with whatever marketing and promotion ResearchChannel and the associated universities might put into this.

And that video of the cute kid summarizing Star Wars? Almost 4 million views in less than two weeks.

I’m a big fan of serious content vs. sound bites, and I think ResearchChannel has their heart in the right place. There are cool examples of videos generated by university types that really take advantage of the medium and are successful in reaching an audience. I have grave doubts, however, about the likelihood that this simplistic mapping of the old lecture model onto (semi-)new technology is gonna get any traction with our son’s generation. I’m sure that some are quite good, and I can imagine that some might be quite popular/successful. But I’m guessing that those are the exceptions rather than the rule, in large part because this model just doesn’t make a lot of sense.

It’s like TED, but four times as long-winded, with less quality control, and worse production values.

Ought to just pull in droves of kids.

Really.

Droves.

I realize that I’m fashionably late for Darwin Day (12 Feb), but I offer cool-scary dinosaur skeletons and flesh-eating beetles in apology!

We were in London Friday to see the Kildegaards who (a) are friends of ours from Morris, (b) are living in Denmark this year on sabbatical, and (c) were in London for a week. We had a wonderful day, which included time in both the Natural History Museum (NHM - where the photo above was taken) and the V&A.

As part of our time in the NHM, we toured the wonderful Darwin Centre. (See the nifty connection? See? See? :->) This included amazing cool things such as a giant squid in a tank, loads of great big animals (mostly fish) preserved in equally big custom-made glass jars (including a Coelacanth and a whole jar of platypi), and flesh-eating beetles! They have a whole room of incubators of flesh-eating beetles that they use to clean specimens without damaging the skeletal structure. And to top off this festival of biological delights, they have a real-time beetle-cam where you can watch the little critters roaming around over the carcass of the moment (in a grainy, low-res format, to be sure), busily contributing to the scientific process. I suspect, in fact, that they will, in their oblivious fashion, will probably contribute more to science than someone like Huckabee.

I want to thank our tour guide (whose name I, sadly but predictably, have forgotten), as she did a great job. She was full of useful information, and handled our numerous questions gracefully and informatively.

As many of my students can attest, I’ve always loved emergent behavior where you have a whole bunch of “stupid” agents working with simple rules, but the end result is amazingly complex and wondrous. There are termites, for example, that by following simple rules (and with no “leader” in charge) manage to build large mounds with extraordinarily precise climate control in certain chambers where they farm special fungi. If you held a gun to my head and told me to use dirt, sticks, and other bits lying around to build a chamber that would be nearly constant temperature day and night, winter and summer, I’d have to tell you to pull the trigger. Yet these insects, with no blueprint or foreman, pull it off over and over again across thousands of years. (Doesn’t evolution just rock!)

No surprise, then, that I was smitten with this recent TED video (of a talk from four years ago) where Deborah Gordon talks about her research into how ants figure out how to allocate tasks (i.e., who does what when).

If you want to play with this sort of thing, I recommend both NetLogo and Breve, as well as this cool Breve-based screensaver, which evolves walking creatures while you’re momentarily distracted from your random web surfing. Both NetLogo and Breve can happily suck up way too much of your life (there are literally days to be spent playing with all the canned models in NetLogo), but it’s great fun, and working with tools like this can really help build your intuition for how complex systems of agents can work.

Below the fold I list some of my favorite NetLogo simulations that I often use in demos.
