MythBusters: Lunar Lunacy
Watch as Kari Byron tries to replicate the NASA footage of a feather and a hammer dropping -- and landing -- at the same time in this video from Discovery Channel's "MythBusters."
Assignment Discovery: Wavelength Basics
There are two types of waves transfer energy: transverse and longitudinal. All wavelengths have similar characteristics whether they are in water or air. Learn more on the Discovery Channel's series, "Assignment Discovery."
Assignment Discovery: Net Force
Multiple forces such as gravity and friction combine to make the net force. Learn more about forces on Discovery Channel's "Assignment Discovery."
Millions of people across the world ride rollercoasters to get the thrill of their lives. Find out what it takes to make some of the fastest rollercoasters work.
Physics: Primal Forces
Learn about the primal forces of the universe-gravity, electromagnetic, the Strong and Weak nuclear force.
Assignment Discovery: Mass Energy Equivalence Formula
On Discovery Channel's "Assignment Discovery," learn about, what is perhaps, Albert Einstein's most startling conclusion, the mass-energy equivalence formula or E=mc squared. It states that energy and mass are linked with the speed of light.
What the Ancients Knew: Buoyancy Defined
Ever wonder why some objects float and others sink in water? Watch and find out as host Jack Turner explains the phenomenon of buoyancy on The Science Channel's series, "What the Ancients Knew."
Assignment Discovery: Issac Newton's Principia
On Discovery Channel's "Assignment Discovery," learn about Sir Issac Newton's book, "Principia," which contains his ideas on how mass interacts with force, inertia and acceleration, and his historic definition of gravity.
Through The Wormhole: Double Vision
This physicist describes the fluctuating properties of light as an experience similar to staring at a barcode on a juice carton while intoxicated.
Through The Wormhole: DIY Wormhole
This physicist is driven to try and construct an actual wormhole that is both predictable and has stable properties. What could go wrong?
