  • Nanotechnology
    • The term itself is a combination of two meaningful parts (what linguists call 'morphemes')
    • +
    NANO TECHNOLOGY
  • What Does ‘Nano' Mean?
    • The 'nano' in 'nanotechnology' is often thought of as a shortened form of 'nanometer‘, which is one billionth (10 -9 ) of a meter. The diameter of one human hair is about 10,000 to 80,000 nanometers.
    A picture of nanofibrils shown with a human hair for reference (Espin Technologies, Inc.) IMAGE SOURCE: http://www.sigmaaldrich.com/Area_of_Interest/Chemistry/Materials_Science/Nanomaterials/Tutorial/Nanotechnology.html
  • Any Unit of Measure
    • However, theoretically, it can be used to refer to one billionth of any measure of interest--for example, a nanosecond refers to one billionth of a second.
    • nanometer
    • nanosecond
    • nanogram
    • nanomole
  • What Does ‘Technology' Mean?
    • TECHNOLOGY : (from the American Heritage Dictionary, 4th Edition , 2000)
      • 1 a. The application of science, especially to industrial or commercial objectives.
      • b. The scientific method and material used to achieve a commercial or industrial objective.
      • 2. Electronic or digital products and systems considered as a group: a store specializing in office technology.
      • 3. Anthropology . The body of knowledge available to a society that is of use in fashioning implements, practicing manual arts and skills, and extracting or collecting materials.
    • How does it differ from 'science'?
    • While the notion of 'science' has often been contrasted with that of 'technology'--the first referring to the building of theory and the second referring to the application of this theory--such a distinction may be blurred in the case of nanoscience and nanotechnology.
  • A Broad Definition: A Popular Perspective
    • Many people understand nanotechnology to be any kind of technology that deals with particles measured in nanometers. This broad definition would include, among other things, thin films, fine particles, chemical synthesis, and advanced microlithography. Scientists, however, tend to find this definition too broad and prefer to call this technology 'nano-scale technology' in contradistinction to '(molecular) nanotechnology'. On the other hand, those in the marketing sector may refer to technology fitting under this broad definition as 'nanotechnology' given its marketing appeal.
    things measured in nanometers technology ‘ nanotechnology’ (nanoscale technology) all things nano
  • A Narrow Definition: A Scientific Perspective
    • Scientists and engineers who are centrally involved in developing this technology sometimes prefer a narrow definition, which they also refer to as ‘molecular nanotechnology’ (MNT). This technology specifically involves manipulating individual atoms and molecules to build structures with complex atomic specifications . Nanotechnology of this sort is still at its infant stages, but products that have been developed include materials that ‘self-heal’ or are relatively lightweight and strong, nano-devices that deliver drugs to the human body, and nano-materials that fuse with human tissue or bone.
    things measured in nanometers technology ‘ (molecular) nanotechnology’ all things nano
  • Meaning as Connotation: A Cultural Perspective
    • Beyond its formal definition—its denotation—it is important to also consider the social meanings of the term—its connotations. Connotations, of course, are culture-specific, and here we discuss only a limited set of social meanings. Perhaps one of the most salient connotations relates to the concept of ‘time.’ As a relatively new technology, most people understand that, until recently, nanotechnology did not exist.
    •  
    technology Things measured in nano units “ONCE UPON A TIME”
    • But in the present time, nanotechnological research is a quickly growing area.
    technology Things measured in nano units “NOW” Meaning as Connotation: A Cultural Perspective
    • Many believe that the technology will continue to develop, yet both the specific prospects and dangers of nanotechnology remain a mystery. While some have great hopes for what this technology can achieve for our society and the world, others remain either skeptical or fearful of what it can do.
    technology Things measured in nano units “FUTURE” ??? Safety Clean water, air World peace Longer and healthier lives End of disease, poverty Modernity ??? Fear Immorality Corporate control Loss of spirituality Loss of privacy Dystopia Meaning as Connotation: A Cultural Perspective

    • Breathable waterproof ski jacket
      • “ Nanotechnology makes the two-layer laminate windproof, waterproof, breathable and grime resistant--great for those bums who don't get around to washing their jackets until after the season. The result: a jacket with a long, functional life superior to coated jackets and competitive with Gore-Tex products.” Forbes 2003
    • Wrinkle-resistant, stain-repellent threads
      • “ Nano-Tex researchers attached molecular structures to cotton fibers, forming a barrier that causes liquids and stains to bead up on the surface and prevent absorption.

    • Nanocrystalline Sunscreen
      • “ Its main ingredient is Z-COTE, a substance made with nanotechnology . . . Nano-dispersed zinc oxide. . . . Zinc oxide provides broad-spectrum protection against UVA and UVB rays, but its characteristic white pasty goop often leaves sunbathers and lifeguards feeling like they're wearing clown makeup. The nanotechnology in Z-Cote produces a high-purity nanocrystalline zinc oxide, which allows the sunscreen to go on clear.” Forbes 2003
  • Products with Protective Coatings
    • Glare-reducing and fog-resistant coatings for eyeglasses and windshields
    • Sunglasses
      • “ To give the glasses antireflection and scratch-resistance functionality, Nanofilm deposits coating layers of 150 nanometers and 20 microns thick, respectively. Then it uses chemical self-assembly to form a polymer coating, three to ten nanometers thin, on the outer layer of the antireflective lenses. This not only seals and repels grime and skin oils but also makes the lenses more responsive.“ Forbes 2003
    • High-Performance Ski Wax
      • “ Nanowax produces a hard, fast-gliding surface. The ultrathin coating lasts much longer than conventional waxing systems, while leaving the base free of buildup. And here's the "intelligent" part: Cerax Nanowax hardens as temperatures drop, adapting to the ski bases and snow crystals, so you can reach top speed from the first few feet on.” Forbes 2003

  • Popular Culture Return to Table of Contents The research for this project is funded by a grant to Elizabeth Keating from Information Technology Services (ITS) at the University of Texas at Austin. Modules created by Elaine Chun.
  • Talking about Nano While many of the specific consequences of nanotechnology are still unknown, talk about nanotechnology is quickly circulating, not only among scientists and engineers but also within cultural realms, such as the media and popular arts.
  • Science Fiction
    • Recent works of popular culture have made reference to nanotechnology, including films ( The Hulk, The Tuxedo, Spider Man ), books ( Prey by Michael Crichton and Diamond Age by Neal Stephenson), television shows ( Star Trek) and video games ( Metal Gear Solid ).
    • While some of these works have been critiqued for inaccurately portraying the risks and potential of nanotechnology, they can be credited for piquing popular interest in the topic.
  • The Possibility of Molecular Manufacturing?
    • Some current books have examined nanotechnology’s potential to transform everyday life from a science-based perspective. Among others:
    • Engines of Creation by K. Eric Drexler
    • Nanotechnology: Molecular Speculations on Global Abundance edited by BC Crandall
    • Our Molecular Future: How Nanotechnology, Robotics, Genetics, and Artificial Intelligence Will Transform Our World by Douglas Mulhall
    • For more works: http:// www.foresight.org/nano/Bookstore.html
    • Some of the ideas in these works have been critiqued as physically impossible, namely the notion of molecular manufacturing , which involves self-assembling molecular structures. According to Professor Richard Smalley of Rice University, self-replicating structures are ‘simply not possible in our world’ and speculation about them does more to hurt rather than help the public’s acceptance of nanotechnology.
  • Arts and Film
    • It has been argued that DVDs have changed the way in which viewers appreciate film as art by allowing viewers to understand the film production process. For instance, we now have access to director’s commentaries on her stylistic choices as well as mini-documentaries that demystify the “making of” a film.
      • With the potential to store even more information on digital media, how else might our understanding of film, and other art forms, change? For example, consider DVDs that store footage of auditions and documentaries about actors’ role preparation as well as their scene-by-scene commentary.
      • What will happen when artists’ interpretations compete with those of ‘experts’ who interpret art for a living?
      • How will this change our ideas of what art is?
  • Fashion
    • Nanotechnology has been used to develop new threads that reflect all light that hits it, allowing fabric to change colors. While initially developed at Massachusetts Institute Technology for soldiers’ uniforms, these threads may soon be used in the fashion world.
    • SOURCE: ( “Clothes That Change Color” )
    • How will the fashion industry be impacted with such ‘smart fabrics’ that both change colors and self-clean?
      • Consider how old fads gain ‘vintage’ prestige. What fashion status will given to fabrics that can become dirty or cannot change colors?
      • Which other accessories will become ‘retro’ and which will simply disappear?
    • GLASSES : Will they be replaced by corrective surgery performed by nano-robots or will they become vintage adornments on the face?
  • Public Figures
    • The development of internet and computer technology has increased the potential to bring the ‘private’ lives of public figures into the public eye. Nanotechnology may facilitate this process as undetectable recording devices and efficient computers contribute to the immediate dissemination of images and sounds.
      • To what degree should the private lives of public figures be respected?
      • What are some ways to regulate the use of nanotechnology to ‘smear’ reputations?

  • Classroom Values: Monitoring Students Radio Frequency Identification (RFID) Systems are not nanotechnological devices, but the current controversy over using electronic tracking systems provides an indication of how local communities may respond to nano-devices that similarly, though invisibly, track human bodies. “In Texas, 28,000 Students Test an Electronic Eye” By Matt Richtel [click title for full text] November 17, 2004, The New York Times SPRING, Tex. - In front of her gated apartment complex, Courtney Payne, a 9-year-old fourth grader with dark hair pulled tightly into a ponytail, exits a yellow school bus. Moments later, her movement is observed by Alan Bragg, the local police chief, standing in a windowless control room more than a mile away. Chief Bragg is not using video surveillance. Rather, he watches an icon on a computer screen. The icon marks the spot on a map where Courtney got off the bus, and, on a larger level, it represents the latest in the convergence of technology and student security. Hoping to prevent the loss of a child through kidnapping or more innocent circumstances, a few schools have begun monitoring student arrivals and departures using technology similar to that used to track livestock and pallets of retail shipments. . . . But there are critics, including some older students and privacy groups like the American Civil Liberties Union, who argue that the system is security paranoia. . . “Elementary school nixes electronic IDs” By Alorie Gilbertm Staff Writer [click title for full text ] February 17, 2005, CNET News.com An elementary school in the rural town of Sutter, Calif., has pulled the plug on a new student surveillance system after the technology came under fire by parents and privacy groups. Brittan Elementary School, located about 40 miles north of state capital Sacramento, is shutting off the high-tech student-tracking system because the company supplying it backed out of the deal, the school said Tuesday. The company, called InCom, put a kibosh on the project after some parents and a representative of the American Civil Liberties Union aired complaints at a school board meeting last week. Their protests became the subject of numerous media reports. Parents and privacy advocates were concerned that student badges containing tiny radio devices would infringe on kids' privacy--and that the radio waves could pose a health risk. . .

Mr. Tripathy invented a technique for “painting” nanoparticles at temperatures below 500 degrees Celsius, making it feasible to apply the dye to rolls and strips of flexible plastic instead of heavier sheets of glass. The technique, which also reduces manufacturing costs, could be used on clothing fibers as well.

    The notion of having private property, while assumed to be a basic right in many societies, is a culturally specific idea; it has held varying importance in different cultures and across time. With the growth of nanotechnology, we may eventually have the potential to “create” all sorts of objects molecule-by-molecule. There may also be an increased emphasis on the ‘ownership’ of intellectual rather than physical property.

    • In some ways, the return of labor to the home setting can be seen as similar to pre-industrial economies when agricultural tasks did not require women and men to separate their work in terms of the ‘private’ and ‘public’ domains, respectively. Both women and men worked performed similar kinds of labor.

  • Economic System
    • The economic system of the United States, as well as other industrialized nations, is often described as being capitalist . In other words, trade and industry are controlled by private owners for profit, rather than by the government, as in a socialist system. Most nations, however, have in fact a combination of the two kinds of systems.
    • One of the main critiques of capitalism is the exploitation of laborers by the wealthy and the perpetuation of social class inequalities.

      • bringing peace because of decreased competition for once scarce resources
  • Will socialism make a comeback?
    • In an essay for Time called “Will Socialism Make a Comeback?” , Francis Fukuyama suggests that socialism in its purest form will never return because of the inherent inefficiency of a central government attempting to regulate a complex market, as well as globalization and information technology allowing citizens to compare their standard of living with those in other countries.
    • Yet “the impulse toward social equality has not disappeared,” he writes. Though governments themselves may not become socialist, societies may depend on nongovernmental organizations (NGOs) to constrain corporations and protect the poor and the environment.
    • Contrary to Fukayama’s argument, to what degree might the increased efficiency of information processing in fact allow central governments to efficiently regulate their market?
    • Given the potential for nations to depend less on other nations because of more widely available resources, how might globalization be affected?
    • How will international trade be affected as nations become more self-sufficient?
    • Currently, the United States exports the following types of products:
    • agricultural products (soybeans, fruit, corn) 9.2%
    • industrial supplies (organic chemicals) 26.8%

  • Violence and Social Unrest
    • Social unrest often results from disenfranchisement which often leads to a sense of desperation.
    • For instance, events in the US such as the Watts riots of 1965 and the LA riots of 1992 as well as nationwide civil rights riots in 1968 were the result of race-based political and economic inequity primarily between whites and African Americans.

    • Violent conflict, while often rationalized and understood as based on racial, ethnic, religious, ethical, or philosophical differences, often has an economic dimension.
    • For instance, violence often erupts between groups competing for scarce resources, as some theorists regard as part of the cause of the Hutu and Tutsi genocide of 1994 in the Central African nation of Rwanda.
    • Even wealthy nations are involved in violent conflict related to economic struggle. For instance, the current war in Iraq is understood by some as related to the maintenance of US dominance in the international oil market.

  • Unequal Distribution
    • Though resources may become both more accessible in general, equally distributing them among nations and communities will be a challenge.
    • Consider how access to both computers and the Internet is not equal across communities and nations, a phenomenon sometimes referred to as the “digital divide.”
    • Given that technology such as digital tools can further advance the economic status of a community and given that such tools are most accessible to wealthier communities, the wealthiest will have the greatest access to means of further wealth production.
  • Unequal Distribution
    • What are some of the ways in which we can prevent a further widening of economic differences between communities as a result of nanotechnological developments?
    • To what extent can we expect wealth to “trickle down” from wealthier to poorer communities and nations?
    • In addition to international treaties and economic cooperation, one of the ways to sustain peaceful relations may be to promote greater cross-cultural understanding.
    • Nanotechnological tools, such as efficient and inexpensive computers and transportation may provide greater opportunities for communication across national borders. And such communication will continue the trend towards a globalized economy.
    • In the past, however, cultural contact has not always led to greater understanding.
    • For instance, economic relations framed as ‘cooperation’, such as the use of labor in non-industrialized nations by corporations in industrialized nations, has sometimes been perceived as exploitation. And the flow of cultural products and ideas, while often influencing youth and class style, has not always been welcomed by all segments of a nation’s population.

  • The Body IMAGE SOURCE: http://www.time.com/time/reports/v21/health/body.html It may become possible for individuals to completely alter their physical appearances either through cosmetic surgery performed by nanorobots or changes in genetic sequences on chromosomes. However, altering one’s physical appearance is not new to our society. For example, body-building, tanning, dieting, tooth-whitening, wearing braces, and wearing color contact lenses can be seen as examples of altering one’s physical appearance. In addition, recently popularized television shows featuring “extreme makeovers” suggest a growing acceptance of cosmetic surgical procedures.
  • The Body

  • Beauty
    • How will this affect attention to physical beauty by both women and men?
    • If everyone has the potential to be ‘flawless’, what will this mean? Will society stop tolerating physical changes that are part of the natural aging process? Or will ‘natural flaws’ come to be something that is aesthetically valued, much as ‘torn’ and ‘faded’ jeans are currently valued?

  • Redefining the Normal Nano-devices that allow individuals to 'fix' physical characteristics deemed fixable by society will affect particular communities that may be seen as non-normative. The use of technology to 'fix' characteristics is now new, however, often resulting from and contributing to the valuing of certain types of physical and cultural characteristics over others. In the Deaf community, for instance, the use of cochlear implants that allow Deaf individuals to hear has resulted in a societal view of Deafness as a 'problem' that can be 'fixed.‘ IMAGE SOURCE: Microsoft clipart

  • Redefining the Normal
    • What are the processes that create social hierarchies?
      • On the one hand, the valuing of particular kinds of skin colors, eye shapes, and physiques can be thought to be arbitrary and culturally specific; no skin color is inherently better than any other.
      • On the other hand, beliefs about beauty are not so arbitrary , given the they are linked to specific hierarchies of power between social groups.

      • Will physical strength become highly desired despite its direct ‘functional’ value?
        • Note that some of today’s affluent communities emphasize physical health despite its lack of necessity for performing daily labor.
    The nantechnological revolution is predicted to place greater value on intellectual rather than physical labor, since nanobots will be able perform the latter. IMAGE SOURCE: Microsoft clipart
  • Risky Behavior
    • How will society’s norms of behavior change?
    • What will our society’s new risky behaviors be?
    With significant advances in medicine, individuals may no longer have fears of behaviors previously thought to be ‘risky’. For example, venereal diseases may be more easily cured and physical damage made more manageable. On the other hand, society’s new emphasis on physical ‘perfection’ may result in a culture of paranoia. IMAGE SOURCE: Microsoft clipart

    • As the average lifespan increases, what will be the linguistic consequence of the coexistence of different generations of speakers?
    • What kinds of community factors will prevent language from changing?
      • Technological means of rigorously enforcing linguistic norms
      • The formation of official language academies, such as the presently existing L’Académie française, that attempt to enforce ‘correct’ ways of speaking.
  • Language Change Dialectologists have shown that dialects often develop when barriers between communities exist, whether such barriers are geographical (mountains or rivers) or social (ethnicity-based communities). As communities are allowed to become self-sufficient through technological advances, new dialects may emerge. On the other hand, many kinds of social boundaries may be ‘erased’ via technologies that allow communication across borders. As history has shown, cross-cultural exchanges have resulted in various kinds of new language practices. For example. . .
  • Dialect Leveling Dialects can merge with one another, a process known as ‘dialect leveling’. Such a process occurred as American English speakers moved westward after the American Revolution, resulting in fewer dialectal differences in the midwestern and western areas as compared to the eastern parts of the US.
  • Hybrid Languages
    • Languages can be mixed and alternated by individuals as a form of ‘code-switching.’
      • An example of English-Korean code-switching:
        • I brought my umbrella biga olgguh gatesuh
        • Gloss: ‘I brought my umbrella because it seemed it would rain .’
    • A community can develop local norms of mixing languages, such as in the case of what is sometimes called ‘Spanglish ’ , which may be viewed as ‘code-switching’ between Spanish and English while also a ‘code’ with its own rules.
    • Sometimes a completely new language may emerge through the combination of the words of one language and the grammatical structure of the other. When such ‘pidgins’ are learned by children, they become ‘creoles’, which have the systematicity and complexity of any language.
  • Lingua Franca
    • In other to communicate, speakers may depend on a common language, or a ‘lingua franca’, chosen by speakers or an officially governing body. Its choice may depend on any number of factors, although the political and economic prestige of the language often plays a major role.
    • What will be the new lingua franca as worldwide communication becomes possible with technological advances?
    Some lingua francas of the past and present a worldwide lingua franca arising originally from British colonial influence and continuing as a result of US economic power English a written lingua franca used for centuries among speakers of mutually unintelligible Chinese dialects Written Chinese the language of the European educated elite during the 17 th to 19 th centuries French the language of colonial administration and trade in 14 th to 16 th century Asia and Africa Portuguese
  • Language Loss As global communication and economic exchange becomes enabled by technological advances, communities may place greater emphasis on the learning of lingua francas that have relative economic value, such as English and Spanish. Linguists have noted that one of the results of such ‘language shift’ is the potential endangerment of less economically valuable languages, eventually leading to their extinction. “ Of the 6,809 languages currently listed in the database of the Ethnologue: Languages of the World, 330 languages each have one million speakers or more. This large size population contrasts sharply with the approximately 450 languages that are so small that they are in the last stages of becoming extinct, with only a few elderly speakers left in each one.” --Barbara F. Grimes, Ethnologue Editor 1971-2000 SOURCE: http://www.sil.org/sociolx/ndg-lg-grimes.html A sampling of endangered languages: Zapotec (Mexico) Menominee (USA) Ainu (Japan) Ratagnon (Philippines) Abaga (Papua New Guinea) Bete (Nigeria) Squamish (Canada) Berbice Creole Dutch (Guyana) Hawai'i Pidgin Sign Language (USA)
  • How can we use technology?
    • Despite the profitability for some societies to learn languages that have economic value, such as English, why is it important to preserve endangered languages?
      • Language is not only a medium for transmitting culture; it is a tightly bound to culture—for instance, in poems, jokes, stories, and ways of expressing culturally-specific ideas. The loss of a language will necessarily result in a significant loss of a people’s culture.
    • How can technology be used to help in the preservation process?
      • Databases for storing and transmitting language samples and verbal art forms
      • Distribution of images and sounds that increase worldwide awareness and valuing of the diverse languages of the world
