The Nature of Matter Understanding the Physical World
Discover how the immense variety of matter--stars, mountains, plants, people--is made by a limited number of elements that combine in simple ways. In the engaging lectures of The Nature of Matter, no scientific background is needed to appreciate everyday miracles like a bouncing rubber ball or water's astonishing power to dissolve. Knowledge of materials drives the development of civilization. Where will we go next?

Episode 20 Recycling Materials
Investigate the ease of recycling some materials, such as aluminum and asphalt, and the impracticality of reusing others, such as certain plastics. Look at the different types of plastic, metal,…
Episode 21 Resistance Is Futile: Superconductors
Under special conditions, some materials lose all resistance to electron flow, becoming superconductors that transmit electricity with 100 percent efficiency. Probe this phenomenon at the atomic level, and learn how…
Episode 22 Resistance Is Useful: Semiconductors
How does a tiny piece of impure silicon launch an electronics revolution? Follow the development of semiconductors from the invention of the transistor in the 1940s to ever-smaller circuits that…
Episode 23 Out of Many, One: Composites
When different materials combine to create something very unlike its individual components, you have a composite. Learn what gives composites superior properties. Explore a wide range of examples, including concrete,…
