Affetto: Child of the Uncanny Valley

You can thank IEE Spectrum and a bunch of roboticists from Osaka University for this excursion into the Uncanny Valley. Meet Affetto, a robot child designed for research into social development psychology. The fully-skinned version is moderately disturbing:

But the skinless facial motion test? Aaaaaaaarrrrgh!

And now I’ve been reminded of it (and we’re all in that creeped-out-by-supposedly-cuddly-technology frame of mind), bring some nineties-retro toy-based trauma to your Tuesday with the naked Furby orchestra:

Bonus material: mechanical “FurbyGurdy” sequencer/synth with MIDI control.

Enjoy your nightmares!

To infinity, and beyond! More inspirational space stuff

Yesterday’s scale-of-space post gathered comments pretty quickly, at least in part due to my own failure to define my terms properly… but it’s a reminder that space still stirs up the imagination like little else, whether one’s imaginings be favourable or dismissive.

And so, here’s some more imagination fuel! As mentioned before, space seems to be clambering back onto the futurist Zeitgeist train of late – a response to the grim economic certainties of the foreseeable future (such as it is)? We all need something to reach for in our dreams, I guess… and if you’re gonna reach, why not stretch to your utmost? The Technology Applications Assessment Team of NASA’S Johnson Space Centre aren’t limiting themselves to anything less than affordable and achievable concepts for manned deep-space missions [via MetaFilter]:

… six technology applications that they are focusing on: satellite servicing, ISRU on the Moon, a SBSP demo, solar electric propulsion vehicle, propellant depots, and the Multi-Mission Space Exploration Vehicle (MMSEV).

[…]

The Nautilus-X MMSEV is intended as a reusable in-space vehicle for cis-lunar and deep space missions. It would offer a sizable volume to sustain a crew of six and hold enough supplies to sustain a two year mission.

Radiation mitigation strategies, such as creating safe zones with water and H2-slush tanks, are being investigated. It is “capable of utilizing variety of Mission-Specific Propulsion Units [integrated in LEO, semi-autonomously]”.

Most strikingly, it would include a ring centrifuge to provide partial gravity for maintaining crew health.

Caveat: “affordable” is a very relative term:

Estimated cost and time: “$3.7 B DCT & Implementation 64 months”

Ouch. Still, pipedreams they may be, but every human achievement was an act of the imagination first, right? But uninformed imagination is just, well, making stuff up… so get yourself over to Centauri Dreams and check out a suggested reading list for people interested in the possibilities of interstellar travel.

Last but not least, and in the name of providing at least one answer to the “sure, we could go there, but what’s the point?” retort, Brian Wang of Next Big Future has excerpts from (and a link to) a speculative PDF report on human population curves after escaping the hard resource limits of Gaia:

NASA studies (Johnson and Holbrow, 1977) confirmed that it was technically possible to build large vista space habitats in free space, essentially anywhere in the solar system (out to the asteroid belt if only solar power were used) with up to about 4 million people in each. In O’Neill’s habitat model the space citizens would live on the inside surfaces of radiation shielded spheres, cylinders, or torus’s which would be rotated to provide Earth normal gravity. The prohibitive Earth launch costs for these massive structures could be off set by using lunar and asteroid materials. Construction of (Glaser, 1974) space solar power satellites by the space colonists would make the project economically viable. Economic break even for the O’Neill-Glaser model was calculated to be about 35 years after which very large profits would be incurred. The result would have been a solar powered Earth and millions of people living in space by the beginning of the twenty first century.

Recently the O’Neill-Glaser model was recalculated (Detweiler and Curreri, 2008) to find the financially optimum habitat size. For simplicity only the habitat size was changed and the financial costs of money and energy updated, while keeping the original 1975 technological assumptions. In order to make the model financially viable the workers must live in space, space resources must be utilized and the community must build Space Solar Power Satellites, SSPS. A net present value plot showing the original calculations (Johnson and Holbrow, 1977) building 10,000 person torus habitats compared to calculations for the habitat size that optimizes costs. Starting the program with smaller habitats (64 – 2000 persons) results in peak costs that are reduced by about 75 percent and one third reduction in time for financial break even (year 25 for the optimized model).

Wildly speculative? Sure it is. So was putting a man into orbit, and not all that long ago.

Space: really very very big

This Lee Billings guest post at BoingBoing sums up the possibilities – given our current understanding of the laws of physics – of travelling to other star systems. Probably won’t be news to many readers here, but even unmanned missions beyond the heliopause will be technologically challenging, hideously expensive and incredibly slow to deliver results. None of which are reasons to write the idea off, though, at least not in my book.

I just wanted to pull out this paragraph, though:

… space is vast, and even the distance to the nearest star is mind-boggling. Let’s say the Sun is the size of a large orange, 10 centimeters in diameter. Place the orange on the ground, walk a bit more than 10 meters away, and you’re in Earth’s orbit. Finding our planet might prove challenging—it would be the size of a millimeter grain of sand. The walk out to Pluto, a speck of dust ten times smaller than our sand-grain Earth, would be nearly a half-kilometer, and along the way you’d be lucky to encounter any of the planets: Even the largest, Jupiter, would be no bigger than a small marble.

That pretty much sums up the sensawunda kick for me. So much space out there… and we’re still arguing over patches of ground and bits of coloured cloth down here at the bottom of the gravity well.

We’ve found a witch; may we fine her?

Via Freakonomics, an odd story out of Romania:

A month after Romanian authorities began taxing them for their trade, the country’s soothsayers and fortune tellers are cursing a new bill that threatens fines or even prison if their predictions don’t come true.

[…]

In January, the government changed labor laws to officially recognize the centuries-old practice of witchcraft as a taxable profession, prompting angry witches to dump poisonous mandrake into the Danube in an attempt to put a hex on them.

After reading that piece, I can’t say I’ve got much pity left for AP’s struggle to monetise their business for a new era; it’s full of dumb racist clichés and stereotypes, for a start (“the land of Dracula”… that’s really the best you could do?), and extraordinarily thin on actual story. But then so is almost every other write-up I can find on the web right now – anyone out there got a Romanian connection for the local viewpoint?

But the Freakonomics mention is my real reason for posting, because – flippant as it may seem – they make an interesting point:

… if I were Queen Witch (for a day), I might frame my argument a bit differently: As soon as the government starts to punish all fortune-tellers — including macroeconomists, financial analysts, government officials, sports pundits and the like — for their wayward predictions, I will gladly join the throng. Until then: no deal.

It’s a matter of accountability: if you make a living from predicting stuff, you should do less well if your predictions are regularly wrong. Personally I’d suggest that governments aren’t in the best place to enforce that sort of accountability – it’s not really in their best interests, as they’re arguably the most consistent sinners – and that this a job for reputation economics and radical transparency. Indeed, as foresight becomes an increasingly important part of pretty much every industry and ideology, increased scrutiny of accuracy is inevitable; there’s probably a really good business model or two lurking in that idea space.

I’m not sure why the witches are so upset, though; homeopathy is a taxable “profession” in the UK, for example, and shows no sign of dropping off the map as a result. No matter what technological leaps me make, I suspect Barnum’s adage – which, appropriately enough, wasn’t even his own adage – will hold true for a long time yet…

The (international) politics of zombies

We’ve looked at possible explanations for the seemingly inexorable rise of the zombie as a pop culture signifier before: are they the American Godzilla, standing in for technology run amok which can only be defeated by frontiersman-like skills with machete and shotgun, or are they – as suggested by Futurismic‘s very own Jonathan McCalmont – a shambling metaphor for a transhuman future?

Well, here’s another take for you: via Crooked Timber, Scott McLemee reviews Theories of International Politics and Zombies by Daniel W. Drezner, which seems to suggest the fear of the zombie apocalypse is, quite simply, the fear of the geopolitical status quo:

[…] if I read him correctly, the author does seem to think that the realist paradigm in international relations theory has a special relationship with the zombie-apocalypse scenario. It rests on the intertwined principles that “anarchy is the overarching constraint of world politics” (that is, there is no “centralized, legitimate authority” able to enforce a particular order among nation-states) and that “the actors that count are those with the greatest ability to use force,” namely “states with sizable armed forces.” While nation-states possessing an advanced military-industrial complex would have a definite advantage in human-zombie combat, the balance of terror is not one-sided. The tendency of zombies to swarm is a staple of movies and fiction; it turns them into something like an army. The logic of the realist paradigm is to treat states as driven by “an innate lust for power.” Likewise, the undead “have an innate lust for human flesh.” Power and flesh alike count as scarce resources. One has an interest in preserving them both.

The realist assumes that powerful nations have — and may expect to continue to enjoy — the advantage over weaker ones in defining the world order. But the tendency of might to create its own right also benefits the zombies. They are single-minded (if that’s how to put it, since they are dead) and can create more zombies just by biting. This gives them enormous power, and that power is highly renewable. Not all realists are zombies, of course; but all zombies, by default, practice realpolitik.

[…]

“Powerful states would be more likely to withstand an army of flesh-eating ghouls,” Drezner writes. “Weaker and developing countries would be more vulnerable to zombie infestation. Whether due to realist disinterest, waning public support, bureaucratic wrangling, or the fallibility of individual decision-makers, international interventions would likely be ephemeral or imperfect. Complete eradication of the zombie menace would be extremely unlikely. The plague of the undead would join the roster of threats that disproportionately affect the poorest and weakest countries.”

A sobering conclusion. In other words, a zombie apocalypse would be terrible — but it would not really change things very much.

That book’s going straight on my wishlist… 🙂
