A Brief History of Time
Part of the Series: Janus Favorites Collection
Errol Morris turns his camera on one of the most fascinating men in the world: the pioneering astrophysicist Stephen Hawking, afflicted by a debilitating motor neuron disease that has left him without a voice or the use of his limbs.…
Chemical Energy, Biomass, and Photosynthesis
Episode 5 of The Science of Energy
Turn now to chemical energy, the potential energy resulting from the position of atoms within molecules. After an overview of photosynthesis (perhaps the universe's most amazing form of energy conversion), learn how combustion transforms biofuels into light and heat, and…
Time
Part of the Series: How We Got to Now
PBS
The world today is obsessed by time. Johnson boards a submarine to discover what a lack of natural light means for a sailor's working day and visits Heathrow, the world's busiest airport, to try to get timings right at air…
Tesla - Master of Lightning
PBS
This program recounts the life of scientist, inventor, and visionary Nikola Tesla, often remembered as more of an eccentric cult figure than an electrical engineering genius. Many of his achievements are still attributed to contemporaries Thomas Edison and Guglielmo Marconi.…
Silicon Run I
Part of the Series: Silicon Run Series
Silicon Run I uses live industrial footage to show the many processes necessary to manufacture microchips, including crystal growth, circuit design, and the wafer fabrication process for CMOS technology. Using close-ups of manufacturing processes and device animation, Silicon Run I…
I Dream of Wires
I Dream of Wires is a documentary about the rise, fall and rebirth of the machine that shaped electronic music: the modular synthesizer. The film explores the synthesizer's remarkable history, revealing how innovators like Robert Moog, working at Columbia University's…
Out of Thin Air
Part of the Series: The Mystery of Matter
PBS
One of science's great odd couples--British minister Joseph Priestley and French tax administrator Antoine Lavoisier--together discover a fantastic new gas called oxygen, overturning the reigning theory of chemistry and triggering a worldwide search for new elements. Soon caught up in…
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…
History's Mysteries
Episode 1 of The Inexplicable Universe
Begin this journey by taking a closer look at concepts that were once unexplainable but are now better understood. You'll focus on two such former mysteries: the existence of an invisible "aether" through which light and sound were believed to…
How Iron and Science Transformed Arch Bridges
Episode 14 of Understanding the World's Greatest Structures
Examine the development of arched bridges during and after the Industrial Revolution. See how the revolutionary Iron Bridge at Coalbrookdale paved the way for the development of science-based engineering. Also, see how science contributed to increasingly sophisticated modern bridges such…
Clean
Part of the Series: How We Got to Now
PBS
Dirty water has killed more humans than all the wars of history combined, but in the last 150 years, a series of radical ideas, extraordinary innovations and unsung heroes have changed our world. Johnson plunges into a sewer to understand…
The Spooky Universe
Episode 2 of The Inexplicable Universe
Did you know that electrons have never actually been observed by scientists to this day? Or that quarks can only be studied in pairs? Or that as you travel faster or find yourself in a higher gravity, time ticks more…
Inexplicable Physics
Episode 4 of The Inexplicable Universe
Turn now to some inexplicable aspects of physics and our physical world. Among the many eye-opening topics you'll learn about in this episode are the discovery of more and more elements on the periodic table; muon neutrinos, tao particles, and…
Light and Quantum Physics
Part of the Series: The Physics of Light
PBS
While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science and technology, but also on our…
The Science of Structure - Forces in Balance
Episode 2 of Understanding the World's Greatest Structures
Explore how two types of external forces: loads (forces applied to structures) and reactions (forces developed at supports, in response to applied loads): act on structures such as Kansas City's Chouteau Bridge. Also, learn how these forces are related to…
Light and Time - The Special Theory of Relativity
Part of the Series: The Physics of Light
PBS
While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science and technology, but also on our…
Computation and Logic Gates
Episode 2 of The Science of Information
Accompany the young Claude Shannon to the Massachusetts Institute of Technology, where in 1937 he submitted a master's thesis proving that Boolean algebra could be used to simplify the unwieldy analog computing devices of the day. Drawing on Shannon's ideas,…
Light
Part of the Series: How We Got to Now
PBS
Johnson relates the story of people who take us out of the dark and into the light. Hear about Edison's light bulb, which he didn't actually invent, and learn how an 18th-century ship's skipper discovered a source of illumination by…
Loads and Structural Systems
Episode 9 of Understanding the World's Greatest Structures
Structures are heavily influenced by the loads they're designed to carry. First, take a closer look at the most important loads structures must resist, including traffic loads and earthquake loads. Then, using the historic iron building at Watervliet Arsenal in…
Catching the Sun
Through the stories of workers and entrepreneurs in the U.S. and China, Catching the Sun captures the global race to lead the clean energy future. Over the course of a solar jobs training program, Catching the Sun follows the hope…
