Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing? Stephen Hawking Science is not only compatible with spirituality; it is a profound source of spirituality.
For The Blind Who Don’t Know Braille You are lucky my friend that you can read this post. Being sight-impaired is not a situation you want to be in. It gets even more complicated if you are blind and can’t even read Braille. Luckily there is some though process being invested in the Braille Interpreter, a single-finger glove that features a tactile sensor, a Bluetooth headphone and interpreting software. The index finger portion of the glove hosts the said tactile sensor.
Here are some words that few would have thought to put together: video game therapy. Yet, a pilot study by vision researchers at the University of California, Berkeley, has found that playing video games can help improve the vision of adults with amblyopia, or lazy eye. The study found that participants experienced marked improvement in visual acuity and 3-D depth perception after spending just 40 hours playing off-the-shelf video games. A UC Berkeley pilot study suggests that video games could help treat adults with amblyopia. “This study is the first to show that video game play is useful for improving blurred vision in adults with amblyopia,” said study lead author Dr. Roger Li, research optometrist at the School of Optometry and the Helen Wills Neuroscience Institute at UC Berkeley.
Fast Company /Video screen capture Nature really knows how to get design right. When it comes to muscles, Mother Nature has come up with a brilliant structure. But could the structure be even stronger? Scientists from the NanoTech Institute at the University of Texas at Dallas are coming up with a way to use carbon nanotubes as the material for muscles modeled after natural structures.
Artist concept of Gravity Probe B orbiting the Earth to measure space-time, a four-dimensional description of the universe including height, width, length, and time. Stanford and NASA researchers have confirmed two predictions of Albert Einstein's general theory of relativity, concluding one of the space agency's longest-running projects. Known as Gravity Probe B , the experiment used four ultra-precise gyroscopes housed in a satellite to measure two aspects of Einstein's theory about gravity. The first is the geodetic effect, or the warping of space and time around a gravitational body.
This week's element is Yttrium, known by the atomic symbol, Y, and the atomic number 39. Originally, its atomic symbol was Yt, but sometime in the early 1920s, it was replaced by Y. This element gets its strange name from the village of Ytterby in Sweden, which is located near where this element was discovered. As you can see in the above image, Yttrium is similar to many other elemental metals; it is a silver-grey in colour. It also is soft, lustrous and highly crystalline. Yttrium is a rare earth metal that never occurs in its pure form in the wild.
It's something you would never expect to go missing, but one of the world's brightest glow-in-the-dark mushrooms has been rediscovered after an absence of more than 170 years, according to USA Today . The bioluminescent shrooms had become a Brazilian legend of sorts. They were first spied in 1840 by an English botanist named George Gardner, who was alarmed after he saw some boys playing with a glowing object in the streets of Vila de Natividad, a village in the Goiás state in central Brazil. After that, no more sightings of the brightly glowing fungus had ever been reported. The mushroom was nearly forgotten until 2002, when Brazilian chemist Cassius Stevani came across Gardner's early reports.
Few motifs of science fiction cinema have been more appealing to us than the subtle defiance of gravity offered by futuristic hovercraft. So every once in a while we check in to see how humanity is progressing on that front, and whether the promise of hoverboards will be delivered by 2015 as evidenced in Back to the Future Part 2 . We’re not quite there yet, but we’re definitely getting off the ground, so to speak.
Kinect-Controlled Robo Maid A Kinect-controlled teleoperated robot can serve as a remotely controlled household servant. DigInfo TV A new household servant robot made by the world’s largest manufacturer of industrial ‘bots can help people with disabilities or limited mobility move things around.
Oct. 25, 2010 Balloon filled with ground coffee makes ideal robotic gripper The human hand is an amazing machine that can pick up, move and place objects easily, but for a robot, this "gripping" mechanism is a vexing challenge. Opting for simple elegance, researchers from Cornell, the University of Chicago and iRobot Corp. have created a versatile gripper using everyday ground coffee and a latex party balloon, bypassing traditional designs based on the human hand and fingers. They call it a universal gripper, as it conforms to the object it's grabbing, rather than being designed for particular objects, said Hod Lipson, Cornell associate professor of mechanical engineering and computer science. The research is a collaboration between the groups of Lipson, Heinrich Jaeger at the University of Chicago, and Chris Jones at iRobot.
PASADENA, Calif.—Researchers at the California Institute of Technology (Caltech) have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. "This is a whole new concept," notes Oskar Painter, associate professor of applied physics at Caltech.
By Daily Mail Reporter UPDATED: 17:29 GMT, 22 November 2011 It was only a couple of decades ago scientists discovered the existence of upwards lightning or ‘sprites’ 30 to 55 miles above the surface of the Earth. And now researchers at Tel Aviv University have discovered 'sprites' are not a phenomenon specific to our planet. Jupiter and Saturn experience lightning storms with flashes 1,000 or more times more powerful than those on Earth, says researcher Daria Dubrovin.
The Kilobots are an inexpensive system for testing synchronized and collaborative behavior in a very large swarm of robots. Photo courtesy of Michael Rubenstein (PhysOrg.com) -- The Kilobots are coming. Computer scientists and engineers at Harvard University have developed and licensed technology that will make it easy to test collective algorithms on hundreds, or even thousands, of tiny robots. Called Kilobots, the quarter-sized bug-like devices scuttle around on three toothpick-like legs, interacting and coordinating their own behavior as a team.
This, we assure you, is a real photograph. Researchers at the University of California Irvine have developed a material that is as strong as metal yet 100 times lighter than Styrofoam. The material is constructed from a micro-lattice of nickel phosphorous tubes that is 99.9% air.
When you meet your robot overlord , it may be wearing super-intelligent skin designed by a Stanford researcher --a solar-powered, super-sensitive, chemical-sampling covering that makes your meatbag covering look pathetic. Zhenan Bao is behind the advances, and the recent development centers on a stretchable solar cell system that can expand and shrink along two different axes, making it perfect for incorporation into artificial skin for robots, human prosthetic limbs, or even clothing. Bao's earlier successes with artificial skin have resulted in a highly flexible and durable material, which is part of a flexible organic-chemistry transistor, built on a thin polymer layer.
