Again and Again: Polymers
Episode 19 of The Nature of Matter
The mystery of a bouncing rubber ball launches you into the study of polymers--long molecules with many repeating subunits. Explore their immense variety, from "poly" synthetics like polyethylene and polyester to organic molecules such as proteins, carbohydrates, and DNA.
Energy and Human Civilization
Episode 1 of The Science of Energy
How much energy is required to power human civilization? What is it that makes our cities, factories, homes, and cars so energy inefficient? How can the average individual affect energy directions? Find out in this overview of how energy touches…
The SI (Metric) System of Measurement
Episode 5 of Chemistry, 2nd Edition Course
Next, you continue to lay a strong foundation for your understanding of chemistry by learning about one of the key tools you'll be using: the International System of Units (SI), or the metric system. This lecture explains why this system…
Materials for Body Implants
