Lesson Plan for Making a Speaker Laboratory ©1995 The Regents of the University of California by Regan Lum Introduction: A speaker is a device that converts an electronic signal into sound. The speaker you will build (see figure 1) consists of a Styrofoam or paper cup, a coil of wire, a permanent magnet, and a signal source. Felix Baumgartner Skydives From The Edge Of Space [11 High Quality Photos] Red Bull is supposed to give you wings bit that would only slow Felix Baumgartner down. This week the daredevil made a test skydive from 18 miles up in preparation for his upcoming jump from 120,000 feet (22 miles) in which he hopes to reach speeds of 690 MPH and be the first person the break the sound barrier. In the latest test jump Felix went 0 to 509 MPH in just 30 seconds and all that is without the aid of a plane fo rocket, just pure gravity baby! Here are photos from his latest jump… Felix Baumgartner hugs Capcom 1 USAF Col (ret) Joe Kittinger after his 96,640 ft free fall from the stratosphere making them the only two people to freefall from that high an altitude. Felix Baumgartner gets lifted up to enter into the capsule.
Think Your Job Is Hard? Watch NASA Crew's Riveting "7 Minutes Of Terror" Mars Landing Last November, the team at NASA launched its Mars Space Laboratory, known as Curiosity, on a long journey through space. On August 6th, the rover will touch down in a crater on Mars and begin its study of climate, geology, and any potential signs of life on the red planet. Although this landing is the culmination of eight months in space, the success of the mission will boil down to what happens in just seven minutes--what NASA refers to as the "7 Minutes of Terror." It will take seven minutes for Curiosity, which has its own Twitter account, to descend from the top of Mars’ atmosphere down to the surface. What will transpire in that time is a marvel of modern ingenuity, which is recounted in suspense-movie-worthy detail in the video above.

LED Lights Make Augmented Vision a Reality LED Lights Make Augmented Vision a Reality Okay, this is just freaky. We know LED lights are versatile enough to be used for practically anything, but LED contact lenses? Really?! Yes, as it turns out, really. University of Washington researchers have figured out how to implant semitransparent red and blue LED lights in contact lenses, for the purpose of receiving and displaying data in sharp visual images and video.
Will Its Violent Death Impact Earth? The red giant, once so large it would reach out to Jupiter's orbit if placed in our own solar system, has shrunk by 15 percent over the past decade in a half, although it's just as bright as it's ever been. "To see this change is very striking," said retired Berkeley physics professor Charles Townes, who won the 1964 Nobel Prize for inventing the laser. "We will be watching it carefully over the next few years to see if it will keep contracting or will go back up in size." Betelgeuse, whose name derives from Arabic, is easily visible in the constellation Orion. It gave Michael Keaton's character his name in the movie "Beetlejuice" and was the home system of Galactic President Zaphod Beeblebrox in "The Hitchhiker's Guide to the Galaxy."
Stars & Planets Scale Comparison A Humbling Perspective"Things are not what they seem, nor are they otherwise." This scale comparison shows "the true place" of Earth and our Sun among the various giants of the universe. It is simultaneously sobering and mind-boggling experience.First series of images opens with the Death Star compared to Mimas, one of Saturn's moons. Note the similarities between the two :) Earth is small enough to be swallowed by an average sunspot:(picture credt) find your palette #d9e8c3 #ced181 #7c8f50 #555e32 #bf867c How Do You Create A Culture Of Innovation? This is the third part in a series by Scott Anthony, author of The Little Black Book Of Innovation. It sounds so seductive: a “culture of innovation.” The three words immediately conjure up images of innovation savants like 3M, Pixar, Apple, and Google--the sorts of places where innovation isn’t an unnatural act, but part of the very fabric of a company. It seems a panacea to many companies that struggle with innovation. But what exactly is a culture of innovation, and how does a company build it?
160 Billion and Counting! (Weekend Feature) The Kepler Space Mission's search for habitable planets is in a tiny window representing 1/400th of the Milky Way. "We used to think that the Earth might be unique in our galaxy," said Daniel Kubas, of the Paris Institute of Astrophysics. "But now it seems that there are literally billions of planets with masses similar to Earth orbiting stars in the Milky Way." According to an analysis of Kepler data this past January, each of the 100 billion or so stars in our galaxy hosts at least 1.6 planets, bringing the number of likely exo worlds to more than 160 billion. Recent research conclude that large numbers of these exoplanets are likely to be small, rocky Earth-like low-mass planets, which appear to be much more abundant than large ones.
Sirius Sirius appears bright because of both its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite, the Sirius system is one of Earth's near neighbors. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to recede, but it will continue to be the brightest star in the Earth's sky for the next 210,000 years. Sirius A is about twice as massive as the Sun (M☉) and has an absolute visual magnitude of 1.42. Engrain Tactile Keyboard by Michael A. Roopenian Wood and Waves Look at your keyboard. Now look at the Engrain. See a difference? The Engrain Tactile Keyboard by Michael Roopenian (say his last name repeatedly please) “uses nature’s tactility to strengthen the relationship between user and interface.” His words, not mine but I I agree.
MIT Creates Amazing UI From Levitating Orbs Anyone else see The Avengers? Just like in Iron Man 1 and 2, Tony Stark has the coolest interactive 3-D displays. He can pull a digital wire frame out of a set of blueprints or wrap an exoskeleton around his arm.
NewsFlash: Rumors Swirling that CERN will Confirm Existence of Higgs Boson Scientists at CERN might be on the verge confirming the existence of what they call the "Higgs boson", according to rumors circulating this week. Higgs, they believe, is a particle, or set of particles, that might give others mass. According to Columbia University mathematician, Peter Woit, "CERN will soon have to decide how to spin this: will they announce discovery of the Higgs, or will they wait for some overwhelmingly convincing standard to be met, such as 5 sigma in at least one channel of one experiment? The bottom line though is now clear: there’s something there which looks like a Higgs is supposed to look. Attention will soon move to seeing if this signal is exactly what the SM [Standard Model] predicts (e.g. will the excesses in different channels agree with SM predictions?)."
