David Boboltz of the National Science Foundation provides information on where to obtain the appropriate glasses to view the solar eclipse. He advises those wishing to view the eclipse to check with their local libraries and various online sources.
In this chapter, the scientists will try to find the best corn to make the biggest popcorn. They will also have a lot of fun with optical illusions. And finally they will show how eyeglasses gather light by using lasers. Part of the House of Science Series.
Parakeet talks about things that make us happy. The first guest, Pig 1, states he is very sad because he spent all Christmas Day in line waiting to buy new Fucci Christmas glasses, but the glasses sold out. His brothers are very sad that Pig 1 missed the family Christmas celebration for a pair of glasses. The fleas show a documentary on Christmas and how it has turned into a commercial holiday. The celebrity guest, Santa Claus, explains that when he was a little boy he cared more about gifts than celebrating with family.
With support from the National Science Foundation, computer scientists at the University of Illinois at Chicago are pushing science fiction closer to reality. They have created a wraparound virtual world in which a researcher wearing 3D glasses can take a walk through a human brain, fly over the surface of Mars, and more. In the system, known as CAVE2, an 8-foot-high screen encircles the viewer 320 degrees. A panorama of images springs from display panels, conveying a sense of being able to touch what's not really there. Part of the National Science Foundation Series “Science Nation.”
Spend a day with Rommie Amaro as she explains what it’s like to be a biophysical chemist.
David Boboltz of the National Science Foundation provides tips for safely viewing the solar eclipse. He advises viewers to use the appropriate glasses leading up to and after the moment of totality.
Host Alex Dainis explains why leaves change colors during the fall. She examines the different colors of leaf pigments by using chromatography. In this experiment, viewers are able to see the various colors of pigments found in leaves.
The invention of the lens goes far beyond the glasses that sit on one’s nose. Galileo used lenses to create the telescope and bring faraway things closer to mankind. At the opposite end of the spectrum, the lens exposed the microscopic world, leading to medical advancements including vaccination, anesthetics, and antibiotics.
Sean Carroll, professor at University of Wisconsin-Madison, discusses the delicate balance of ecological systems. He explains how one seemingly minor change in one species can upset an entire ecosystem. Part of the "Ask a Scientist" series.
The parakeet starts with a monologue about the secrets. The first guest, the leg, is outraged by the betrayal of the frog: he read his diary without permission. The frog doesn't consider himself a traitor and says that everything happened by accident. The fleas share a documentary on espionage and the media. The famous guest, the princess of pop, shares how fame has affected her and how hard it has been to maintain her privacy.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on how to appropriately dress when conducting experiments in a science lab. For example, students should always wear personal protective equipment. This includes aprons, safety glasses, and gloves. Part of the Science Video Vocab series.
Cyborg technology is a revolutionary development in rehabilitation medicine. It allows the brain and nervous system to manipulate specially engineered devices that help people regain the use of impaired body function. Once a dream of science fiction, this revolutionary technology is now becoming a reality. Demostrates a deep brain stimulation that can help stop the violent shaking of victims of Parkinson's disease. Presents two professors from the State University of New York and Duke University who discuss their cutting-edge research.
Kathy Blake is blind but two years ago she got a glimmer of hope. She heard about an artificial retina being developed by a company called Second Sight and the Doheny Eye Institute in Los Angeles. It was experimental, but Kathy was the perfect candidate. With funding from the National Science Foundation, a camera is built into a pair of glasses, sending radio signals to a tiny chip in the back of the retina. The chip, small enough to fit on a fingertip, is implanted surgically and stimulates nerves that lead to the vision center of the brain.
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.
Mobile computing is accelerating beyond the smartphone era. Today, people wear smart glasses, smart watches, and fitness devices, and they carry smartphones, tablets, and laptops. In a decade, the very same people are likely to wear or carry tens of wireless devices and interact with the Internet and computing infrastructure in markedly different ways. Computer scientist Xia Zhou is working to make sure there are no traffic jams with the increased demand. With support from the National Science Foundation, Zhou and her team at Dartmouth College are developing ways to encode and transmit all that data faster and more securely. Part of the "Science Nation" series.
Solutions are uniform mixtures of molecules in which any of the phases of matter can be dissolved in another phase. Whether solids, liquids, or gases, solution chemistry is important because most chemical reactions, whether in the laboratory or in nature, take place in solutions. In particular, solutions with water as the solvent are the core of all biology. Extending the particle model of matter to solutions enables chemists to predict what will happen to a deep-sea diver who breathes different mixtures of gases or to the life forms in the ocean as carbon dioxide levels rise in the atmosphere. Part of Chemistry: Challenges and Solutions Series.
