Quantum motor with just two atoms

Quantum-motorResearchers at the University of Augsburg in Germany have developed a blueprint for a kind of quantum electric motor that uses just two atoms:

Their motor consists of one neutral atom and one charged atom trapped in a ring-shaped optical lattice. The atoms jump from one site in the lattice to the next as they travel round the ring. Placing this ring in an alternating magnetic field creates the conditions necessary to keep the charged atom moving round the the ring.

As with many elements of quantum physics it is difficult to imagine precisely what you could do with such a miniscule motor, but for the time being the researchers are seeking to attach the motor to a nanonoscopic resonator, thus making the resonator vibrate.

In the meantime we are left speculating as to what peculiar corners of which unexpected futures devices such as this could find a use and a narrative.

*tap, tap* Is this thing on?

Hi folks;

If you noticed that Futurismic was unreachable for a large part of the last twelve hours or so, please accept my apologies – unexplained downtime is just one of the many extras that come bundled with our web hosting service! Everything appears to be back to normal now, though (touch wood).

If you didn’t notice Futurismic was down… well, you can pretend you never saw this post, right? Right.

Normal service – as normal as it ever gets round here, anyway – should be restored soon… just about as soon as this hangover clears up, in fact (this really hasn’t been the best Friday ever). Thanks for your patience. 🙂

Kim Stanley Robinson asks why science fiction isn’t winning awards; I ask why we should care

Science fiction heavyweight Kim Stanley Robinson crops up in the current edition of New Scientist to sing the praises of British sf… and of sf in general. In addition to presenting flash-length pieces by a handful of big names – Ken MacLeod, Geoff Ryman, Justina Robson and more – he has a lengthy article decrying the blinkered tastes of the juries for awards like the Booker Prize:

… it seems to me that three or four of the last 10 Booker prizes should have gone to science fiction novels the juries hadn’t read. Should I name names? Why not: Air by Geoff Ryman should have won in 2005, Life by Gwyneth Jones in 2004, and Signs of Life by M. John Harrison in 1997. Indeed this year the prize should probably go to a science fiction comedy called Yellow Blue Tibia, by Adam Roberts.

This is hardly a new complaint – fandom has always muttered darkly into its real ale about the shunning of science fiction by the literary establishment, and this year saw some Guardian book bloggers attempt to redress the imbalance by running an open-nomination “Not The Booker” Prize (only to see all the genre titles swiftly voted out of the running, natch) – but to have it appear on the pages of New Scientist is an interesting development. Indeed, NS seems to be quite deliberately aligning itself with a science fictional/futurist mindset of late; perhaps the editorial team are equally convinced of sf’s didactic and educational powers as Robinson is?

Personally, I’ve always felt that prizes and public acceptance are overrated, and that science fiction does itself a disservice by chasing after them; Robinson appears to me to be taking a similar stance. I’ve never picked books because they won awards; personal recommendation has always carried far more weight, ever since I was quite young.

And if we truly believe that science fiction has the power and potential to open minds (and change them), isn’t the sincere recommendation of a book from friend to friend the best form of evangelism? To use an analogy with science itself: many of the greatest scientific innovators achieved their leaps of progress in spite of great public opposition and the opprobrium of the establishment; rather than kowtow and beg for crumbs of approval, they just knuckled down and got on with it, fueled by their own defiance, converting their few faithful supporters through their unflappable loyalty to their own ideas.

Don’t get me wrong, here: I’d love to see the authors I admire being paid more, or being interviewed as insightful pundits rather than geeky fringe artists who are good for ridiculous out-of-context quotations. I’d love to see science fiction as a powerful and accepted part of modern cultural discourse… but I don’t think it’ll ever achieve that through us pleading for legitimacy on its behalf.

As recent events have shown, hearts and minds aren’t won with shock and awe; they’re won with honesty and sincerity. If you care enough about science fiction that you want to see it read more widely and appreciated as something more than simple escapist entertainment, don’t waste your time storming the ramparts of the crumbling ivory tower of literature, or decrying the inevitably populist results of fan-voted awards. Instead, try to convert one other book-lover. If all of us managed to do that, we’d double the power of the genre almost overnight, and weaken the factional schisms within it at the same time.

Rant over. 😉

A bearing on magnetic north growing farther away all the time

compassScience writer Quinn Norton tests a new sense, that of always knowing what direction North is via an ankle-attached bracelet that indicates true north using vibrations from eight internal buzzers:

The Northpaw is based on the Feelspace, a project organized by the Cognitive Psychology department of Universität Osnabrück in Germany. The principle is simple and elegant. The buzzers signal north to the wearer. The wearer gets used to it, often forgetting it’s there. They just start getting a better idea of where they are through a kind of subconscious dead reckoning.

Quinn has written about similar direction-sensing enabling technologies before.

I recall something like this in Lords and Ladies by Terry Pratchett. PTerry gifts his elves with “poise” – the ability always to know where they are.
