4 Important Rare Earth Elements Sir William Crookes, a 19th century British chemist, once wrote that, "rare earth elements perplex us in our researches, baffle us in our speculations and haunt us in our very dreams." These weren't easy elements to isolate or to understand, and so there was a very long lag time between the discovery of the rare earths, and the discovery of practical uses for them. It didn't help that individual rare earth elements don't occur by their lonesome—they travel in packs. To get one, you have to mine all of them. Europium was the first isolated, high purity rare earth element to enter the public marketplace, in 1967, as a source of the color red in TV sets. At the time, rare earth mining wasn't even a twinkle in China's eye. Today, europium is still used as a phosphor, but as cathode ray tube TVs go the way of the dodo, it's more likely to turn up in white LED-based lights, which could someday be an energy efficient replacement for both incandescent and compact fluorescent bulbs.
SF Signal - A Speculative Fiction Blog An Atlas of The Universe Small world by Ralph C. Merkle Xerox PARC 3333 Coyote Hill Road Palo Alto, CA 94304 merkle@xerox.com This is an extended web version of the article published in the Feb/Mar 1997 issue of MIT Technology Review. Introduction Manufactured products are made from atoms. Since we first made stone tools and flint knives we have been arranging atoms in great thundering statistical heards by casting, milling, grinding, chipping and the like. That's changing. Build products with almost every atom in the right place. One warning: in contrast to the useage in this article some researchers use the word "nanotechnology" to refer to high resolution lithographic technology while others use it to refer to almost any research where some critical size is less than a micron (1,000 nanometers). There are two main issues in nanotechnology: What might molecular manufacturing systems look like? Second, such models give us a feel for what molecular manufacturing systems might look like. The advantages ofnanotechnology
TrekMovie.com | the source for Star Trek news and information Molecular Movies Go Hollywood BioVision's latest animation shows how food is converted into energy. By John Roach, Contributing Writer, NBC News Biologists are using the kind of animation technology you might see in a multimillion-dollar "Toy Story" movie to show the general public how molecules inside a cell work. The resulting high-tech visual aids have found their way into thousands of high-school classrooms, and they've been watched millions of times on video-sharing websites such as YouTube. "It is very much about how do you put science in context, how do you take advantage of the fact that we are visual animals, that we in fact understand the world through our eyes to a significant degree, and apply that reality of who we are as animals to the way in which we perceive science," he told me. Behind the scenesThe team's latest animation, "Powering the Cell: Mitochondria" shows how molecules inside the cell convert food into energy. "The Inner Life of a Cell" is a fantastic voyage based on real biology.
How Nanotechnology Works There's an unprecedented multidisciplinary convergence of scientists dedicated to the study of a world so small, we can't see it -- even with a light microscope. That world is the field of nanotechnology, the realm of atoms and nanostructures. Nanotechnology is so new, no one is really sure what will come of it. In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. As small as a nanometer is, it's still large compared to the atomic scale. In a lecture called "Small Wonders:The World of Nanoscience," Nobel Prize winner Dr. In this article, we'll learn about what nanotechnology means today and what the future of nanotechnology may hold. In the next section, we'll learn more about our world on the nanoscale.
The Story Of The Pioneer Plaque – Beginning Pioneer 10 was the first object made by humans to ever go past the solar system and travel into the universe at large. It was a spacecraft that was sent by NASA to methodically snap photos of Jupiter and beam them back to Earth. But it also carried with it pictures of it’s own that were etched into a small golden plaque. These pictures are intended to communicate very specific stories to anyone or anything Pioneer 10 might come across in it’s voyage across the galaxy. NASA didn’t originally intend to send such an unusual object out with Pioneer 10. It was only through the efforts of someone as dedicated and charismatic as Carl Sagan that it even had a remote chance of being approved by NASA administrators. Sagan had been approached by two people who had heard that Pioneer 10 was set to be the first spacecraft to ever leave the solar system and they had come up with an idea of sending a message out with it. ‘…where we are, when we are, and who we are.’ Humans.
The Biomechanics of Good Running | Playbook AUSTIN, Texas — If you’re a runner and you can’t extend your hip well behind you on your stride, Jay Dicharry has bad news: You’re never going to be a great runner. [bug id="sxsw2012"]This doesn’t mean you should hang up your shoes. You can still run, and run well, but not everyone can attain the ideal stride needed to be a truly great runner. Dicharry is the director of the Speed Performance Clinic and the Motion Analysis Lab Coordinator At The University Of Virginia. “I’m from New Orleans, and there’s great food there,” he said, by way of understatement. Most runners don’t extend their hips, Dicharry said. Along with a lack of hip extension, overstriding is one of the biggest sins. Even elite athletes can fall prey to these pitfalls in form, as Dicharry demonstrated with a tape of the mens’ 800-meter finals at the 2011 NCAA outdoor track and field championships. “Look at their gait,” he said. “There’s more to it than just running,” Dicharry said of winning. Third, kneel on one knee.
