University of Nottingham scientists discuss electrons: their mass, dimensions, movements, behavior, and other concepts that are too elusive to fully understand, even for physicists. An interesting look at experiments that help us grasp more knowledge of electrons' behaviors. [6:46]

University of Nottingham professors discuss energy, and show the conversion of potential energy to kinetic energy through a variety of simple demonstrations. [4:25]

University of Nottingham scientists discuss the importance of big "G", or Newton's universal gravitational constant, and little "g", or the force of gravity here on Earth. [8:45]

First seen by Galileo in 1610, Jupiter is known for its many moons, its massive size, and its use in the first measurement of the speed of light. University of Nottingham physicists discuss what we've learned about Jupiter since its discovery and how this planet has aided us in understanding important physics concepts. [6:49]

Scientists explain what a magnetic field is, in everyday science and in astronomy. See examples of magnets and magnetic fields, as well as an example of an electromagnet. [8:25]

University of Nottingham's Dr. Richard Hill explains magnetic susceptibility and how, using a powerful magnet, he can make a drop of beer to levitate. [7:58]

Physicists and astronomers have different views of photons, what they are, and how they behave. Watch as three University of Nottingham scientists discuss the nature of photons and why the study of light is important. [8:32]

University of Nottingham's Professor Roger Bowley shows you a piece of polaroid--the type of material in sunglasses--and demonstrates how the direction of its molecules prevents glare. [8:43]

A University of Nottingham physicist explains how a jet engine works, and demonstrates a jet engine's propulsion efficiency using a water-propelled rocket made from a soda bottle. [6:01]

University of Nottingham astronomers talk about telescope diameter, and how the size and quality of a telescope's mirror determine what we see when looking through it. Offers a look at the opportunities offered by the "Extremely Large Telescope", which will be built with a lens over forty meters in diameter. [8:31]
