Information Processing: The Age of Computing - 0 views

  • By their less than wholly objective accounts of the development of physics, historians have conspired to propagate the myth of science as being essentially theoretical physics. Though the myth no longer described scientific reality 50 years ago, historians pretended that all was well, that nothing had changed since the old heroic days of Einstein and his generation.

      Don Ihde discusses this predisposition toward theoretical physics in his book Philosophy of Technology.
  •  
    ...Historians of science have always had a soft spot for the history of theoretical physics. The great theoretical advances of this century -- relativity and quantum mechanics -- have been documented in fascinating historical accounts that have captivated the mind of the cultivated public. There are no comparable studies of the relations between science and engineering. Breaking with the tradition of the Fachidiot, theoretical physicists have bestowed their romantic autobiographies on the world, portraying themselves as the high priests of the reigning cult.

25% of US car accidents due to using gadgets | KurzweilAI - 0 views

  •  
    Driving distractions such as cell phones and other electronic devices cause as much as 25% of all U.S. car accidents, researchers at the Governors Highway Safety Association have found, WinBETA notes. A major finding was that being distracted was the cause of 15 to 25% of all accidents, ranging from minor property damage to death. Their findings suggest that distracted driving accidents be reported in accident reports to assist in evaluating distracted driving laws and programs. They propose creating low-cost roadway measures that alert motorists when they are drifting out of their driving lane. They also propose that all cell phones be banned on the road, even hands-free versions. In another report by The New York Times, police in Syracuse and Hartford have handed out nearly 20,000 tickets for illegal use of a phone while driving - either for texting or use of a handheld phone. According to the federal government, these efforts have had the desired effect: distracted driving has fallen sharply. Their research shows that drivers talking on a phone are four times as likely to get into a crash as those not on a phone, and that the risks for motorists who text are at least twice as high. In Syracuse, handheld cellphone use and texting have each fallen by one-third. In Hartford, handheld cellphone use by drivers fell 57 percent while texting fell by 75 percent, the Times reports.

Why Big Media Is Going Nuclear Against The DMCA | TechCrunch - 0 views

  •  
    When Congress updated copyright laws and passed the Digital Millennium Copyright Act (DMCA) in 1998, it ushered an era of investment, innovation and job creation.  In the decade since, companies like Google, YouTube and Twitter have emerged thanks to the Act, but in the process, they have disrupted the business models and revenue streams of traditional media companies (TMCs).  Today, the TMCs are trying to fast-track a couple of bills in the House and Congress to reverse all of that. Through their lobbyists in Washington, D.C., media companies are trying to rewrite the DMCA through two new bills.  The content industry's lobbyists have forged ahead without any input from the technology industry, the one in the Senate is called Protect IP and the one in the House is called E-Parasites.  The E-Parasite law would kill the safe harbors of the DMCA and allow traditional media companies to attack emerging technology companies by cutting off their ability to transact and collect revenue, sort of what happened to Wikileaks, if you will.  This would scare VCs from investing in such tech firms, which in turn would destroy job creation. The technology industry is understandably alarmed by its implications, which include automatic blacklists for any site issued a takedown notice by copyright holders that would extend to payment providers and even search engines.   What is going on and how exactly did we get here?

Social networking's good and bad impacts on kids | KurzweilAI - 0 views

  •  
    Social media present risks and benefits to children but parents who try to secretly monitor their kids' activities online are wasting their time, says Larry D. Rosen, Ph.D., professor of psychology at California State University, Dominguez Hills. Rosen identifies potential adverse effects of social media, including: Teens who use Facebook more often show more narcissistic tendencies, while young adults who have a strong Facebook presence show more signs of other psychological disorders, including antisocial behaviors, mania, and aggressive tendencies. Daily overuse of media and technology has a negative effect on the health of all children, especially preteens and teenagers, by making them more prone to anxiety, depression, and other psychological disorders, and making them more susceptible to future health problems. Facebook can be distracting and can negatively impact learning. Studies found that middle school, high school and college students who checked Facebook at least once during a 15-minute study period achieved lower grades. Rosen says new research has also found positive influences linked to social networking, including: Young adults who spend more time on Facebook are better at showing "virtual empathy" to their online friends. Online social networking can help introverted adolescents learn how to socialize. Social networking can provide tools for teaching in compelling ways that engage young students. "If you feel that you have to use some sort of computer program to surreptitiously monitor your child's social networking, you are wasting your time. Your child will find a workaround in a matter of minutes," he says. "You have to start talking about appropriate technology use early and often and build trust, so that when there is a problem, whether it is being bullied or seeing a disturbing image, your child will talk to you about it."

Humanity Needs to Keep Pace with Technology (cont'd) | The Veracious Blog - 0 views

  •  
    When we talk about participation, we have to be a bit more specific. On the publishing side, there's clearly more participation than we've ever seen in the past. But in order for this tidal wave of information to be useful, we need to be able to separate fact from fiction. We need to encourage participation on the receiving end. What we need is evaluating participation. With the breadth of niche information and sources we have the ability to get at the best of what is known on a myriad of topics and contexts. Every niche has its experts and its hacks, its enthusiasts and detractors. But for the remaining 95% of us who are not subject matter experts, deriving the accurate or useful information from the sea of what is available can be complicated, time-consuming and simply unverifiable. We need a way to quantify the value of information, or more specifically, the veracity of information.

Make plastic objects appear before your eyes - 0 views

  •  
    Everyone has experienced a broken knob or a broken piece off of an appliance. You also know that while trying to get a new one you might have a long waiting period. Well there might be a prototype that is here to solve that problem. The Thing-O-Matic claims to manifest any three-dimensional plastic object in just minutes. The machine was shown first at a Las Vegas trade fair and is meant to make manufacturing more common for the average person.\n\n3,000 have already been sold at $790 a device. This model only makes plastic objects but the manufacturers say that in the future models could make metal and plastic models to make super cool gadgets. The machines make objects that are six by six by seven inches. The machine is not capable of making images but it does make boxes, tubes and get this- even action figures!

  •  
    RepRap is a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap can print those parts, RepRap is a self-replicating machine - one that anyone can build given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too.Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. Our community portal and New Development pages have more information on how to get involved. Use the links below and on the left to explore the site contents. You'll find some content translated into other languages.RepRap is described in the video on the right.

Researchers create light from 'almost nothing' - 0 views

  •  
    (PhysOrg.com) -- A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced from the virtual particles that have been thought to exist in a quantum vacuum. In a paper published on arXiv, the team describes how they used a specially created circuit called a superconducting quantum interference device (SQUID) to modulate a bit of wire length at a roughly five percent of the speed of light, to produce visible "sparks" from the nothingness of a vacuum.

Historic first images of rod photoreceptors in the living human eye - 0 views

  •  
    ScienceDaily (June 9, 2011) - Scientists have just reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics (AO), the same technology astronomers use to study distant stars and galaxies, scientists can see through the murky distortion of the outer eye, revealing the eye's cellular structure with unprecedented detail. This innovation, described in two papers in the Optical Society's (OSA) open access journal Biomedical Optics Express, will help doctors diagnose degenerative eye disorders sooner, leading to quicker intervention and more effective treatments.

5 Things That Internet Porn Reveals About Our Brains | Sex & the Brain | DISCOVER Magazine - 0 views

  •  
    With its expansive range and unprecedented potential for anonymity, (the Internet gives voice to our deepest urges and most uninhibited thoughts. Inspired by the wealth of unfettered expression available online, neuroscientists Ogi Ogas and Sai Gaddam, who met as Ph.D. candidates at Boston University, began plumbing a few chosen search engines (including Dogpile and AOL) to create the world's largest experiment in sexuality in 2009. Quietly tapping into a billion Web searches, they explored the private activities of more than 100 million men and women around the world. The result is the first large-scale scientific examination of human sexuality in more than half a century, since biologist Alfred Kinsey famously interviewed more than 18,000 middle-class Caucasians about their sexual behavior and published the Kinsey reports in 1948 and 1953. Building on the work of Kinsey, neuroscientists have long made the case that male and female sexuality exist on different planes. But like Kinsey himself, they have been hampered by the dubious reliability of self-reports of sexual behavior and preferences as well as by small sample sizes. That is where the Internet comes in. By accessing raw data from Web searches and employing the help of Alexa-a company that measures Web traffic and publishes a list of the million most popular sites in the world-Ogas and Gaddam shine a light on hidden desire, a quirky realm of lust, fetish, and kink that, like the far side of the moon, has barely been glimpsed. Here is a sampling of their fascinating results, selected from their book, A Billion Wicked Thoughts.

New laser technology could revolutionize communications | KurzweilAI - 0 views

  •  
    Engineers at Stevens Institute of Technology have developed a technique to optically modulate the frequency of a laser beam and create a signal that is disrupted significantly less by environmental factors, says Dr. Rainer Martini. The research provides for enhanced optical communications, allowing mobile units not tied to fiber optic cable to communicate in the range of 100 GHz and beyond, the equivalent of 100 gigabytes of data per second. Eventually, the team hopes to extend the reach into the terahertz spectrum. The frequency or amplitude modulation of middle infrared quantum cascade lasers has been limited by electronics, which are barely capable of accepting frequencies of up to 10 GHz by switching a signal on and off.  Marini and his team have developed a method to optically induce fast amplitude modulation in a quantum cascade laser to control the laser's intensity. Their amplitude modulation system employed a second laser to modulate the amplitude of the middle infrared laser, using light to control light. The current detector is only capable of detecting frequencies up to 10 GHz, but Dr. Martini is confident that a new detector will make the system capable of much higher frequencies. With an optical system that is stable enough, satellites may one day convert to laser technology, resulting in a more mobile military and super-sensitive scanners, as well as faster Internet for the masses, says Martini.

First successful transplantation of a synthetic windpipe | KurzweilAI - 0 views

  •  
    A 36-year-old man has received the world's first synthetic trachea, made from a synthetic scaffold seeded with his own stem cells, in an operation at the Karolinska University Hospital in Stockholm, Sweden. Professor Paolo Macchiarini of Karolinska University Hospital and Karolinska Institutet led an international team, including professor Alexander Seifalian from University College London, who designed and built the nanocomposite tracheal scaffold, and Harvard Bioscience, which produced a specifically designed bioreactor used to seed the scaffold with the patient´s own stem cells. The cells were grown on the scaffold inside the bioreactor for two days before transplantation to the patient. Because the cells used to regenerate the trachea were the patient's own, there has been no rejection of the transplant and the patient is not taking immunosuppressive drugs. "The big conceptual breakthrough is that we can move from transplanting organs to manufacturing them for patients," says David Green, the president of Harvard Bioscience in Holliston, Massachusetts. Transplantations of tissue-engineered windpipes with synthetic scaffolds in combination with the patient's own stem cells as a standard procedure means that patients will not have to wait for a suitable donor organ. Patients could benefit from earlier surgery and have a greater chance of cure. This would be of especially great value for children, since the availability of donor tracheas is much lower than for adult patients.
