Plenty of Room at the Bottom’s 50th anniversary; new advance in nanoassembly; satirizing the copyright wars; China’s social media map

There’s plenty of room at the bottom, Richard Feynman’s December 29, 1959 talk for the American Physical Society is considered to be the starting point or origin for nanotechnology and this December marks its 50th anniversary. Chris Toumey, a cultural anthropologist at the University of South Carolina NanoCenter, has an interesting commentary about it (on Nanowerk) and he poses the question, would nanotechnology have existed without Richard Feynman’s talk? Toumey answers yes. You can read the commentary here.

In contrast to Toumey’s speculations, there’s  Colin Milburn (professor at University of California, Davis) who in his essay, Nanotechnology in the Age of Posthuman Engineering: Science Fiction as Science, suggests that nanotechnology originated in science fiction. You can read more about Milburn, find the citations for the essay I’ve mentioned, and/or download three of his other essays from here.

Ting Xu and her colleagues at the US Dept. of Energy’s Lawrence Berkeley National Laboratory have developed a new technique for self-assembling nanoparticles. From the news item on Physorg.com,

“Bring together the right basic components – nanoparticles, polymers and small molecules – stimulate the mix with a combination of heat, light or some other factors, and these components will assemble into sophisticated structures or patterns,” says Xu. “It is not dissimilar from how nature does it.”

More details are available here.

TechDirt featured a clip from This hour has 22 minutes, a satirical Canadian comedy tv programme, which pokes fun at the scaremongering which features mightily in discussions about copyright. You can find the clip here on YouTube.

I’ve been meaning to mention this tiny item from Fast Company (by Noah Robischon) about China’s social media. From the news bit,

The major players in the U.S. social media world can be counted on one hand: Facebook, MySpace, Twitter, LinkedIn. Not so in China, where the country’s 300 million online users have a panoply of popular social networks to choose from–and Facebook doesn’t even crack the top 10.

Happy weekend!

As I’ve been exploring ideas around multimodal discourse and sensing, this article, Tech gives humans animal senses, caught my eye. Animals see and/or hear more than humans do unless the human had access to a virtual reality display at the SIGGRAPH09 conference (August 3 – 7, 2009) in New Orleans. From the article by Jason Palmer on BBC News,

The virtual reality scene is based loosely on Cocos Island, west of Costa Rica, and visitors to the exhibit can wander through the island’s forests or swim in its tropical waters, navigating with the aid of a modified Nintendo Wii game controller.

They can switch between ranges of sounds or sights that they might see.

An ultraviolet setting paints a picture rich with both normal colour and reflections we can’t normally see. Visualisation expert Fred Parke has designed the system such that it corrects for perspective as users navigate the space. The programme allows visitors to hear the infrasound vocalisations of whales or the ultrasound clicks of tiger moths.

(There’s more here including a video [prefaced by a Blackberry ad featuring U2] of visitors enjoying the display.) The article goes on to mention that animals have senses that we don’t, for example, “sharks’ ability to sense electric fields.” It’s true true you don’t have that sense unless you’re a body hacker,  “a subculture of people who embed magnetic chips into their bodies so they can sense magnetic and electromagnetic fields thereby giving themselves a sixth sense.” (I posted about body hackers here in my exploratory series about robotics and human enhancement) I’m not coming to any conclusions; I’m exploring possible connections and in that context, the interest in extending senses beyond their ‘normal’ range or adding senses come from various sectors seems significant.

On another note, it seems like a good time to mention Heather Haley’s videopoetry event which will take place in Vancouver at Pacific Cinémathèque (usually) in November. Right now she’s asking for submissions,

SEE THE VOICE: Visible Verse 2009

Call For Entries

Nearing 10 years of screenings! Please help spread the word. Thanks!

Pacific Cinémathèque and curator Heather Haley are seeking videopoem submissions from around the world for the annual Visible Verse screening and performance poetry celebration. SEE THE VOICE: Visible Verse is North America’s sustaining venue for the presentation of new and artistically significant poetry video and film.

Official guidelines:

* Visible Verse seeks videopoems, with a 15 minutes maximum duration.
* Either official language of Canada is acceptable, though if the video is in French, an English-dubbed or-subtitled version is required for consideration. Videos may originate in any part of the world, however.
* Works will be judged on true literary merit. The ideal videopoem is a wedding of word and image, the voice seen as well as heard.
* Please, do not send documentaries, as they are outside the featured genre.
* Videopoem producers should provide a brief bio, full name, and contact information in a cover letter. There is no official application form nor entry fee.

Send, at your own risk, videopoems and poetry films/preview copies (which cannot be returned) in DVD NTSC format to: VISIBLE VERSE c/o Pacific Cinémathèque, 200–1131 Howe Street, Vancouver, BC, V6Z 2L7, Canada. Selected artists will be notified and receive a screening fee.

DEADLINE: Sept. 1, 2009

Moving from the artsy to the commercial, the movie GI Joe opened this weekend with a villain determined to take over the world by using nanotechnology weapons. Yes, nanobots or, for this movie, nanomites. Unfortunately, the critics are more interested in excoriating the film than in explaining the ‘technology’ and my eardrums are not up to the task of watching the film but it does seem that this is another variation of K. Eric Drexler’s nanoassemblers eating up the world scenario from his book, Engines of Creation. In contrast, scientists continue their every day nanotechnology research, (from the media release on Phyorg.com)

Today’s advances in nanofabrication include the manufacture of micro- and nano-machines with moving parts separated by distances less than a micron (a micron is a millionth of a meter; a single strand of hair is approximately 100 microns). Because the distances are extremely small, the Casimir force needs to be considered in the design and function of the micro/nano-machines for efficient operation.

“The Casimir force, which is usually attractive, is also large at short separation distances between objects,” explained Mohideen, a professor of physics and the principal investigator of the grant.
