The Condition of Nano-dernity

Chris Toumey’s new article, “Cubism at the Nanoscale,” (2007) looks to the Cubist movement of the early twentieth century to provide cues for how to go about representing nanoscale structures today. Because nanoscale materials are too small to be photographed, the images that we see representing them are the product of a “multistage process that begins with touching the nanoscale, not seeing it, and converting tactile sensations into data, which are later converted into visual sensations” (587). For Toumey, this threatens a problem of credibility should the public discover that representations of nanoscale materials do not have the same “optical veracity” as photographs. To address this (and setting aside the question of the veracity of photographs), Toumey looks to Cubist approaches to representation, particularly their attempts to simultaneously represent multiple dimensions of an object. Drawing on cubist techniques, Toumey poses three suggestions for creators of representations of nanoscale structures: add a temporal dimension through the use of multiple, sequential images; add color(s); add a tactile dimension that permits deeper engagement of the viewer with the nanoscale representation.

While these suggestions are fine and no doubt useful for those concerned with promoting certain public perceptions of nanotechnology, Toumey’s adoption of Cubist techniques runs contrary to their Cubist intent. Cubists, unlike Toumey (c.f. 587), had no interest in improving the correspondence between an image and reality. Indeed, Cubism marked a tremendous social upheaval, manifested in a variety of social domains, and which centered on a crisis in traditional conceptions of reality and knowledge. Concern for the veracity of a representation is a preoccupation that Cubists directly questioned. Through the abandonment of classic techniques of painting, including representations of Euclidean space, and the refusal to view painting merely as a tool for the representation of nature, Cubism rejected enlightenment rationality. In turn, Cubism sought multiple modes of representation, resulting in fragmented objects unrecognizable to those who thought that painting should replicate nature. This constituted a profound loss of faith in the connection between knowledge and progress; between signified and signifier; between rationality and an objective reality.

Toumey hails Cubism to take us in the opposite direction: to better represent the empirical nature of nanoscale materials. This divergence is made clear by Toumey’s characterization of the goals of Cubists to enlarge “the viewer’s knowledge of the reality of the object in a picture.” I argue that the goal for Cubists was rather to challenge the very possibility knowledge as coherent and singular. This challenge and crisis manifest in the Cubist movement is forgotten in Toumey’s characterization. His application of Cubist aesthetics to representations of nanoscale structures is thus remarkably un-Cubist to the degree that it seeks to “add to our empirical knowledge of the objects that exist at the nanoscale” (589).

Thinking about representation at the nanoscale, however, does raise some interesting questions. What Cubism and Toumey’s invocation of it in the context of nanotechnology are grappling with are the limitations of representation in the context of shifting relationships between space and time. Following Harvey (1989), if cultural modernism sprang from a “radical readjustment in the sense of time and space in economic, political and cultural life” (260-1) then by analogy, we might see the problem of representation at the nanoscale as a similar readjustment of our sense of time and space – a radical continuation of time-space compression. If, as the forecasters suggest, we are on the front end of a major readjustment to the world economy and to our many manners of living as a result of nanotechnological innovation, perhaps Toumey is out front by hinting at a similar crisis in representation to that which began after the middle of the 19th century. As the commercialization of nanotechnology floods our lives with events, practices, and produts that may be undetected by human sensory organs, whose risks or benefits are frequently invisible, the understanding and expression of social meanings takes on new dimensions. How will we represent those aspects of human experience that are invisible, un-touchable, un-smellable but powerful, potentially dangerous, and highly profitable?

Private Enterprise Leads the Way to Clean Water

Here's one current nano-enabled invention that could do the world a lot of good: a water-purifier with a filtration system capable of screening out particles as small as 15 nm - small enough to filter out viruses.

I find it fairly interesting that the Lifesaver's website features a soldier. I have nothing against soldiers getting their clean water. But I hope that these water filter systems also find their way to others who desperately need clean drinking water.

Because images from science fiction really do help...

Italian physics & engineering professor Nicola Pugno generates a lot of discussion (at least in blogosphere) for his scientific work and predictions on carbon nanotubes. Last year, he predicted that carbon nanotubes, even in all of their theorized glory, wouldn't be strong enough for a space elevator cable.

This year, he's more optimistic. No, the space elevator is still a no-go. But he does have high hopes for scaling walls Spiderman-style.

Why does Dr. Pugno catch my eye? His use of science fiction images is not likely to be an accident. When he writes about taking elevators into space or climbing up walls with special adhesive clothing, he invokes strong, myth-like, associations for a range of people- including many who probably don't spend lots of time trolling around peer-reviewed scientific journals.

Our good friend (and CNS Fellow Alum), Aaron Rowe, has an interesting take on the global race to create a nanotechnology infrastructure ** His Wired blog entry also inspired some commentary at IEEE's blog, about how nanotechnology infrastructures won't bring about the "nanotech revolution."

While both Aaron and Dexter, the IEEE blogger, make some good points about government-supported research initiatives, I particularly support one of Dexter's secondary points, his take on nanotechnology as an enabling technology - meaning that nanoscale technological innovations are most likely going to be tools for other technologies.

Toasty Feet another Nano Product

To show people what sorts of products can be improved by nanotechnology, educators often use stain resistant pants and tennis balls that retain their air longer. My mom called the toasty feet insoles to my attention. Blogger Marlene Bourne ranked them as one of the top ten consumer products that make use of nanoparticles.

From the aerogel website, "Aerogel, the advanced nonporous material in Toasty Feet, has the highest thermal insulation value of any solid material available today, allowing it to retain heat efficiently, while remaining light and thin enough to fit comfortably in almost any shoe or boot."

I would lean towards calling this a clever use of materials science rather than nanotechnology. The lines between those fields are often quite fuzzy. In any case, they look like some nice insoles.
