There’s a new renewable energy player in town, and it’s about to make waves in the industry. Despite its massive potential as a source for renewable energy, the ocean is unlikely to contribute meaningfully to electricity supplies without dramatic, innovation-driven reductions in the cost of energy conversion. That’s where engineers Balky Nair, Rahul Shendure, and Tim Mundon come in with their company, Oscilla Power. With support from the National Science Foundation, they’re developing a utility-scale wave energy harvester called the Triton. This technology shows promise as a means for delivering utility-scale electric power to the grid at a price that is competitive with conventional fossil or renewable technologies. Part of the National Science Foundation Series “Science Nation.”
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story;" approach to explaining these natural phenomena. In this episode, it is night time and Moko can't sleep. Looking out to the horizon, he notices a shot of color at the water's surface. He wakes Mei-Lei to ask her what he is seeing. Together they take a barge and set off. Under them, a rainbow of colors is dancing in the waves. Moko and Mei-Lei think that the fish must be organizing a party and decide to dive in. Bit by bit the sun is rising and day is breaking. The two friends return to the village, overjoyed at the wonders of the ocean.
At first glance, the bone-dry landscape of the Atacama Desert in Chile might seem inhospitable. But, it’s prime real estate for astronomers. This desert is now home to the largest ground-based radio telescope in the world called the Atacama Large Millimeter/submillimeter Array or “ALMA for short. And, it’s allowing astronomers to see the universe like never before. Part of the National Science Foundation Series "Science Nation."
With support from the National Science Foundation's Directorate for Social, Behavioral, and Economic Sciences, psychologist Brad Duchaine and his team are studying the brains of 20 people with "face blindness." The team hopes to better understand the computational and neural basis of face processing in general. The research will help scientists develop a classification system for the condition and advance understanding of how different face-processing abilities are organized in the brain. Part of the "Science Nation" series.
The arctic ground squirrel has developed highly specialized adaptations to extreme environments. This species maintains circadian rhythms throughout the arctic summer, despite the almost ceaseless daylight during this period. The squirrels’ body clocks have evolved to work just fine without the help of the day/night cycle. With support from the National Science Foundation, physiological ecologist Cory Williams of the University of Alaska, Anchorage, and a team of researchers traveled to the Toolik Field Station in northern Alaska to study the arctic ground squirrel on its home turf. Part of the National Science Foundation Series “Science Nation.”
Kit Parker is a lieutenant colonel in the Army Reserve and has served multiple tours of duty in Afghanistan. Even when he’s not in uniform, this Harvard University bioengineer makes it his mission to protect the men and women of the U.S. armed forces. Parker and his team are developing next-generation nanofibers at the Harvard Materials Research Science and Engineering Center (MRSEC). The unlikely inspiration for Parker’s team is none other than the cotton candy machine. They use their own version of that technology to spin a wide range of polymers, both natural and synthetic, into new fabrics and materials for military use. Part of the National Science Foundation Series “Science Nation.”
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. After the illuminating light show at Walkerville's old theatre, Arnold's bossy cousin Janet claims she could put on a much better show. Nobody believes her until Janet and Arnold mysteriously disappear. Ms. Frizzle leads her class into the darkened theatre to look for them. To shed some light on the problem, the kids become beams of light.
Dr. Michelle Thaller explains infrared light. Due to its longer wavelengths than those of visible light, infrared light is invisible to the human eye. However, special equipment exists that makes these wavelengths visible. Part of the "Ask an Astronomer" series.
This album of eight computer-animated video segments looks at the particle approach to studying light by exploring the antithesis of the wave model. Presents black-body radiation, Planck's constant, the photoelectric effect, and the work of James Clerk Maxwell as forerunners to Einstein's concept of photon frequency. Shows examples of a slope-intercept graph and a revised double-slit experiment using light-sensitive paper segue to an illustration of the Compton effect, establishing that light consists of a stream of particles. De Broglie's contributions introduce wave-particle duality, which some might consider an inadequate solution, although it represents the best that current science can do.
Discover how scientists compare the reflected red, blue, and green light from planets in the solar system to identify distant planets. Carolyn Crow, an astronomer, describes how the amount of green, blue, and red light reflected by planets can be plotted. A diagram compares the color data of the planets and shows that Earth is easily distinguishable by its blue color.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. There's something dazzling in Ms. Frizzle's closet: a magical, light-powered pinball machine. To win at this game, the kids have to light up all six colors of the rainbow. Now the race is on, as the class shrinks down and zooms into the pinball machine. They will have to learn how to reflect all of the light to combine it into one beam to make their escape.
How did 20th-century physics change long-held notions of light's makeup and behavior? This group of 12 concise computer-animated videos illustrates Einstein's monumental contributions to the study of light. Shows how rudimentary ideas of material wave motion yielded to more advanced concepts of electromagnetic waves by detailing Einstein's conclusions about the speed of light and his conception of time, which-given his findings on mass and energy-proceeds according to variable frames of reference. Conveys relativistic thought experiments through helpful animation, which demonstrate simultaneity, time dilation, length contraction, and relativistic mass.
The speed of light is constant in a vacuum, but what about in the everyday world? Examines the behavior of light as it passes through physical substances in a collection of 23 computer-animated video shorts. Outlines Ptolemy's Law of Refraction and the concept of angle of incidence by examining light's motion through air, water, glass, and other media. Explores Snell's Law by highlighting the importance of a refractive index along with displacement, deviation, dispersion, and the role of refraction in fiber optics. Studies lens types including biconvex, convex meniscus, plano-convex, and concave models, in addition to telescopes, magnifying glasses, and the human eye.
Stuart Rowan, a professor at Case Western Reserve University, has created polymers that are able to self-heal when heat is applied using a special light. Part of the Fast Draw Series.

Part of the "A 3-D Demonstration" series. Defines electric power and explores in general terms a variety of means by which it is produced, transmitted, and consumed. Discusses energy conservation in relation to power production, transmission, and consumption with a particular focus on the efficiencies and inefficiencies associated with the conversion of electricity to light. Specific modules include Efficiency I: Power Production, Power, Efficiency II: Power Transport, Power Transmission, Power Consumption, Inefficiency I: The Light Bulb, and Inefficiency II: The Fluorescent Bulb. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Infrared light is all around, and the universe literally glows with it everywhere. However, humans are not able to see infrared light because it is just outside the limits of the human eye. With a simple injection, scientists gave mice the ability to perceive near-infrared light. What does this mean for humans? Part of the "Uno Dos of Trace" series.
If the sun instantly switched off like a light bulb, it would take almost 8 and a half minutes before humans on Earth realized what happened. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth. This means the sunlight that reaches Earth is old. How is that possible? It is due to the concept of random walks. Part of the “It’s Okay to Be Smart” series.
Visible light, which can be seen with human eyes, comprises a small sliver of the electromagnetic spectrum. The rest of the spectrum, from short wavelength gamma rays to long-wavelength radio waves, requires special instruments to detect. ALMA uses an array of radio telescopes to detect and study radio waves from space. ALMA is an advanced tool for studying very old stars and galaxies. These objects now are seen at great cosmic distances, with most of their light stretched out to millimeter and sub-millimeter wavelengths by the expansion of the universe. ALMA provides the unprecedented ability to study the processes of star and planet formation.
