    Science week on PM

    A listener to Radio 4's PM programme got in touch recently asking why it did not get more scientists involved directly in its output.

    So, for a each day this week, the programme has spoken to one scientist about the work they are doing, to try to learn more about what impact their work might have, and why a scientist chooses their particular field of inquiry.

    The idea was to break out of the topical habit of only ever inviting scientists on to explain a particular story just because it is in the news, and learn about what scientists are up to when they are not being talking heads on a particular programme.

    THE VISIONEERS AND THE MARKETING OF SCIENCE

    The Visioneers: How a Group of Elite Scientists Pursued Space Colonies, Nanotechnologies, and a Limitless Future

    http://www.amazon.com/The-Visioneers-Scientists-Nanotechnologies-eb...

    In 1969, Princeton physicist Gerard O'Neill began looking outward to space colonies as the new frontier for humanity's expansion. A decade later, Eric Drexler, an MIT-trained engineer, turned his attention to the molecular world as the place where society's future needs could be met using self-replicating nanoscale machines. These modern utopians predicted that their technologies could transform society as humans mastered the ability to create new worlds, undertook atomic-scale engineering, and, if truly successful, overcame their own biological limits. The Visioneers tells the story of how these scientists and the communities they fostered imagined, designed, and popularized speculative technologies such as space colonies and nanotechnologies.

    Patrick McCray traces how these visioneers blended countercultural ideals with hard science, entrepreneurship, libertarianism, and unbridled optimism about the future. He shows how they built networks that communicated their ideas to writers, politicians, and corporate leaders. But the visioneers were not immune to failure--or to the lures of profit, celebrity, and hype. O'Neill and Drexler faced difficulty funding their work and overcoming colleagues' skepticism, and saw their ideas co-opted and transformed by Timothy Leary, the scriptwriters of Star Trek, and many others. Ultimately, both men struggled to overcome stigma and ostracism as they tried to unshackle their visioneering from pejorative labels like "fringe" and "pseudoscience."

    The Visioneers provides a balanced look at the successes and pitfalls they encountered. The book exposes the dangers of promotion--oversimplification, misuse, and misunderstanding--that can plague exploratory science. But above all, it highlights the importance of radical new ideas that inspire us to support cutting-edge research into tomorrow's technologies.

    Cubic boron nitride, a material that in many ways resembles diamond. Boron nitride can be compressed into a superhard, transparent form—but unlike diamond and many other materials known for their extreme hardness, it is based not on carbon but on a latticework of boron and nitrogen atoms. Computer simulations have indicated that a rare crystalline form of boron nitride would resist indentation even better than diamond if it could be synthesized into large samples, and laboratory experiments have shown that more attainable forms of the stuff already approach the hardness of diamond.

    Now a new set of experiments on a nanostructured form of boron nitride have yielded even greater measures of hardness than before. The new material exceeds that of some forms of diamond, according to the authors of a study reporting the findings in the January 17 issue of Nature.

    The samples had a measured hardness of up to 108 gigapascals—slightly harder than synthetic diamond but less hard than polycrystalline diamonds made of nanoscale grains.

    yes but my idea dear Challa is good also for reasons that you have indicated and so for founding institute of arts in IIT of INDIA is good

  • Andrea

    i really think that with international riha journal for art history you should found in IIT in INDIA  a section of MIT of BOSTON for ARTS

  • Dr. Krishna Kumari Challa

  • Andrea

    i have not understood this comment but i think my idea is good i would like to know your opinion, really...

  • Andrea

    for me in this period as seeing what in Russia is happening in cultural field theese types of research are importants with founding some correlate institutions where it needs and for example also in Ucraina not only in India is need an institute that is for me of estethic correlate to mexico for the fact that some many characteristics are really similars and i have a demonstration of an artist of Ukraina that could prove this.

    Russia is not only in itself and not only european... is also caucasic cultural and for understanding this and improve also communication technologies perhaps the foundation of an institute in Ucraina is the right way.

  • Andrea

    it is a great pity that you not respond me..

    bye

  • Andrea

    in every case if you see or contact jojo marengo of world art foundation you could tell the same thing

    i'm sure that he will listen you...

    bye

  • Andrea

    i think that is not a confusion idea and that is good..

    Side-Dominant Science: Are You Left- or Right-Sided?
    Each person's brain is divided into two sides—the left and right hemispheres. In some cases, one hemisphere may be more active than the other during a certain activity. For example, when someone processes language, one hemisphere is usually more active than the other. Doing this or other activities, however, is not absolutely limited to using one hemisphere or the other, or even certain hemispheric parts. Different brain areas are important and work together for different activities, such as speech, hearing and sight. But if part of a hemisphere is damaged when a person is young, other parts of the brain can often take over doing whatever the damaged regions of the brain used to do.

    What do the brain's hemispheres have to do with sidedness? When someone is processing language, one hemisphere is usually working harder than the other. There is also some correlation between the side(s) we use in our brain and the side we use on our body. This preference to use one side of the body over the other is known as sidedness, laterality or left/right dominance.

    Scientific literacy
    Scientific Literacy

    The United Nations agency UNESCO has defined literacy as an individual's ability to "read and write a short simple statement relevant to his everyday life." Scientific literacy does not imply that a person must be learned in matters of science, but it does not suffice that a person be able to read and write. It rather means functional literacy, the ability to comprehend what is read or written to an extent sufficient to perform adequately in society, whether to communicate with individuals, to further one's own economic or other interests, or to participate in the democratic way of life. Scientific literacy implies the ability to respond in a meaningful way to the technical issues that pervade our daily lives and the world of political action.

    Scientific literacy does not require knowing the definition of angular momentum or that the expression of DNA is mediated by transfer–RNA molecules. But a scientifically literate person would know that astrology is not science and that children are not born with stronger muscles just because their parents exercise in the gym. Scientific literacy implies that whether or not a person endorses a program for water fluoridation or for building a nuclear power plant is based on some understanding of the issues at hand, rather than on prejudice (that all tampering with natural resources is harmful or unambiguously beneficial) or ignorance that decisions involve trade–offs, as might exist between a nuclear and a coal–fueled plant.

    Two increasing demands of modern nations establish the universal need for scientific literacy. First is the need for a technically trained labor force. Second is the requirement that citizens at large pass judgment on the promises and actions of their governments and on the claims of advertisers of consumer goods.

    The productive sector of the economy of any industrial nation demands a scientifically literate labor force. Scientific and engineering breakthroughs are the basis of industrial productivity. But economic and industrial development more immediately come from the adaptation of scientific ideas: new materials and manufacturing processes, quality control, advances in productivity and the performance of workers, and consumer appeal and marketing. The successful implementation of scientific and engineering innovations requires cadres of educated workers skilled in the management of machinery, computers, control centers, quantitative information and materials.

    The need for scientific literacy extends beyond industry to other sectors such as agriculture. The recent greatly increased agricultural productivity in the United States and other countries is largely attributable to the introduction and application of modern farming practices and the use of machinery that requires skilled operators.

    Scientific literacy is also required for informed public involvement in the political and public life of a nation. Whether or not a highway system will be developed, and if so, where and how; how to protect and improve the water supply and air quality; the exploitation of mineral or marine resources; the preservation and commercial use of forests, rivers and coasts—these are among the numerous political decisions that call for the participation of the body politic.

    A participatory democracy will not be consummated if the import of the technical premises of political decisions with great economic consequence, and which affect the present and future welfare of a nation, can be understood only by a small fraction of the population. A public that has no inkling of the technical issues at stake exposes the democratic process to exploitation by special interests and demagogues, and even to fraud of the kind that masks pseudoscience, such as astrology or parapsychology, with the cloak of science.

    ENT science:Art and science of sword swallowing
    The art of sword swallowing has a lot to do with science
    The practice dates back 4,000 years, when priests in India swallowed swords to demonstrate their supposed supernatural powers and connection to the gods.

    Today, sword swallowing is a popular act in circuses and sideshows, and has diversified to include even more dangerous feats. Some performers tackle other objects, such as saws or fluorescent tubes, and some even swallow multiple swords at the same time. The record is more than 20.

    Although professional sword swallowers make these incredible feats look easy, the art -- or science -- of sword swallowing is one that takes years to learn and even longer to master. Beginners learn from an experienced performer and follow the 7 x 7 rule-- practising seven times a day, seven days a week for many years, before they're ready to perform. The main challenge they face is learning to become aware of parts inside the body that we normally don't have any control over.

    When a sword is swallowed, the path it takes in the body is the same path that your food takes when you eat -- from the mouth, to the throat, through the esophagus, and into the stomach.

    First, the sword swallower must straighten their spine and tilt their head back. This positions the body in a straight line, ready for the sword to enter. Next, they need to relax the muscles at the back of the throat to allow the sword to pass through.

    In this way, sword "swallowing" is actually a misnomer. When you swallow, you're contracting those muscles in your throat to send food towards your stomach.

    Finally, the sword swallower needs to relax two more keys sets of muscles -- those at the top and bottom of the esophagus -- before the sword passes all the way down to the bottom of the stomach.

    Sword swallowing is not a hoax or a trick. Many people think that sword swallowers use a collapsible sword, or a fake sword made of plastic -- but rest assured, it's a real metal sword.

    Swallowers constantly dull and buff the edges because even a small nick or scratch can cause serious injury. If you were to touch a sword swallower's sword, which you can do in the exhibition, you would notice that it's not sharp enough to cut your skin. However, the soft lining inside your body does not have the same protection, and sword swallowers can puncture the esophagus if they try to swallow before their mind and body are ready.
