"This intriguing 6-part PBS documentary series explores the concepts of physics from familiar theories, such as Newton's Law of Gravity, to the latest in scientific research, like string theory and M-theory. By connecting all of this research with the medium of light, we can gain a deeper understanding not only of our immediate reality, but of the unseen realities that are hidden beyond our perception. Starting with Einstein's Theory of Relativity, Physics of Light explores the true nature of light, peers inside the atom, and looks ahead to the most cutting edge theories in physics."

"In the 24 lectures of The Science of Energy: Resources and Power Explained, award-winning professor and expert geophysicist Michael E. Wysession of Washington University in St. Louis presents an unbiased investigation into the energy sources that power our world. Vividly illustrated with animations, 3-D graphics, graphs, in-studio demonstrations, and other visuals that make scientific and mathematical concepts approachable and understandable, The Science of Energy is a marvelous window into the inner workings of energy that will keep you constantly engaged."

"This engrossing series takes a spectacular journey into the world of sound—and reveals what the physics of sound can tell us about the world and how it works. Scientist Helen Czerski uncovers the miasma of mathematical waveforms that combine to create each sound. She explores the secrets that sound can unlock, from the structure of the universe to the way that animals communicate over thousands of miles. Packed with spectacular imagery, jaw-dropping experiments and some of the most remarkable sounds in the world, this is the ultimate guide to one of the universe’s most magical phenomena."
