Carbon-Fiber Car of the Future

In this video segment adapted from NOVA, hear physicist and energy expert Amory Lovins explain how to make more efficient cars by making them lighter and more aerodynamic. Explore how the use of carbon fiber can reduce weight without reducing size or durability, and learn about some manufacturing ch

Are Engineered Nanoparticles Dangerous?

We'll be tackling the risks of nanoparticles and other particles more fully when Risk Bites launches formally in November. But until then, here's a roller-coaster ride of a video on what might be important when thinking about the risks and benefits or nanoparticles - or any other particles for that

The Index of Refraction and Snell’s Law

In this video from the ICT Center, learn about the index of refraction and Snell's law. Review a simple example of refraction, the speed of light in materials and the formula for calculating the index of refraction. Explore a table of the refractive indices of common media and materials used in fibe

Making Boats Fly

Learn how advances in technology allow boats to go faster than ever before in this video from NOVA: “Making Stuff Faster.” Host and technology columnist David Pogue examines two factors that limit speed—energy and resistance—and describes how Oracle Team USA maximizes the speed of its boat. Instead
