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 of a traditional sail, the boat has a rigid carbon-fiber wing that acts as an airfoil to create lift and propel the boat forward. In addition, foils on the underside of the boat lift it largely out of the water, which reduces the drag force exerted by the water on the boat. This video is available in both English and Spanish audio, along with corresponding closed captions. CREDITS: LICENSE:

The Dynamic Sun

In this video from NOVA’s Sun Lab, learn about the Sun’s ever-changing surface and magnetic field. Images and animations illustrate how the Sun’s magnetic field lines are affected by the motion of the Sun’s plasma. Over time, the magnetic field becomes twisted and more complex, which increases solar

The Anatomy of the Sun

In this video from NOVA’s Sun Lab, learn about the Sun’s composition and structure. The Sun is a plasma, primarily made of hydrogen with smaller amounts of other elements. Animations and images illustrate the physical and behavioral properties of the Sun’s six regions: the core, radiative zone, conv
