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. The electronic signal goes through the coil and creates a varying electromagnet. figure 1 Purpose: In this laboratory, you will explore how a speaker works. Materials: 1 permanent magnet 2 feet of wire 1 pencil tape or glue 1 Styrofoam or paper cup 1 signal source (tape player) 1 plug with alligator clips for tape player Procedure: Assemble material as shown in figure 1. Leaving about 10 centimeters on the end, wrap the wire around a pencil to make a wire coil and tape or glue it to the bottom of the cup. Conclusion Does the volume control on the tape player work on your speaker? Return to CEA Science Education Home Page
Science Space Photo of the Day | Wired Science When the lamp is shattered, The light in the dust lies dead. When the cloud is scattered, The rainbow's glory is shed. These words, which open Shelley’s poem "When the Lamp is Shattered," employ visions of nature to symbolize life in decay and rebirth. It's as if he had somehow foreseen the creation of this new Gemini Legacy image, and penned a caption for it. Polar-ring galaxies are peculiar objects. Models of how polar-ring galaxies form offer two general formation scenarios: 1) a piercing merger between two galaxies aligned roughly at right angles, or 2) when the host galaxy tidally strips material from a passing gas-rich spiral and strews it into a ring. Born of Violence Brian Svoboda of the University of Arizona, who recently studied the chemical and temperature environment of NGC 660, believes that unique morphology arises from a previous interaction with a gas-rich galaxy.

LED Lights Make Augmented Vision a Reality | Elemental LEDucation 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? Once miniature green LEDs are developed (and they’re in the works, as of now), full color displays will be possible. Lead researcher Babak Parvis comments “You won’t necessarily have to shift your focus to see the image generated by the contact lens,” it would just appear in front of you and your view of the real world will be completely unobstructed when the display is turned off. Ah, the real world. Thanks to Extreme Tech for the quote and Trendhunter for the images. By the way, these freaky LED contact lenses may still be a product of the future, but a lot of cool LED products are of the present!

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? While culture is a complicated cocktail, four ingredients propel an organization forward: the right people, appropriate rewards and incentives, a common language, and leadership role-modeling. The Innovator’s DNA Has Four Components If you ask most people what makes a great innovator, the most common response is innate gifts from parents or a higher power. At the core is what the professors call “associational thinking.” Questioning: Asking probing questions that impose or remove constraints.
Higgs Found Finally, physics’s zoo of subatomic particles is full. Scientists have almost certainly snared the Higgs boson, the last particle waiting to be roped into the fold. Decades after it was proposed, the Higgs emerged in the shards of particle collisions at the world’s most powerful accelerator, the Large Hadron Collider at the CERN laboratory near Geneva. Physicists announced the discovery on July 4 during a seminar at the lab. “We have now found the last missing cornerstone of the standard model,” said Rolf-Dieter Heuer, CERN’s director-general. “It’s the beginning of a long journey to investigate all the properties of this interesting particle.” The particle’s mass is around 125 billion electron volts, or about 133 times the mass of a proton. A computer visualization depicts one array of particle debris that physicists would expect from the decay of the Higgs boson in the Large Hadron Collider, the world's largest particle accelerator.
Engrain Tactile Keyboard by Michael A. Roopenian Wood and Waves Look at your keyboard. Now look at the Engrain. 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. Those moments aren’t just sci-fi fun; they’re full of visionary ideas to explore and manipulate objects in 3-D space. Jinha Lee, from the Tangible Media Group of the MIT Media Lab, in collaboration with Rehmi Post and Hiroshi Ishii, has been playing with the idea of manipulating real floating objects in 3-D space to create a truly tactile user interface. It’s essentially a small field in which gravity doesn’t overcome an object. “There is something fundamental behind motivations to liberate physical matter from gravity and enable control. Interviewing Lee, I realized he’s one-part scientist, one-part philosopher. Whereas we are captivated by this empty pocket of air, Lee has hidden the real magic just above where there’s a 3-D actuator housing an electromagnet.

August 22, 2013 Artist’s Work Paints a Beautiful Picture Animations Tyrus Wong, a 102-year-old artist’s work influenced the visual direction of Bambi in 1941. An exhibition at the Walt Disney Family Museum in San Francisco will be held to celebrate Wong’s work. According to the Disney Museum site, the drawings felt different from what is commonly known for Disney animation and this is what caught Walt Disney’s eye.

Pop-Up Corner Lamps Illuminate those Hard-to-Light Places Standing lamps in corners often feel a bit like round pegs in square holes, not quite fitting the space in a way that would feel intentional. This flat-pack, fold-out solution from Well Well Designers is a low-cost and elegantly-designed approach that is minimalist in terms of both materials and appearance. The product packaging and typography are all comprehensively considered in form and function – this is not a typical in-the-box retail object, but a simple black (or blue or red) on white approach. “The Pop-up corner light is delivered in an envelope. The lamp is constructed from a sheet of polypropylene. The sheet is cut and incised, in such a way to produce a square, triangular or circular module when folded at a 90° angle.
