Inexplicable Physics
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 the three regimes of matter; the secrets of string theory;…
History's Mysteries
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 travel and the orbit of Mercury, which seemed to violate…
Why Time Is a Mystery
Begin your study of the physics of time with these questions: What is a clock? What does it mean to say that "time passes"? What is the "arrow of time"? Then look at the concept of entropy and how it holds the key to the one-way direction of time in…
Time Travel
Use a simple analogy to understand how a time machine might work. Unlike movie scenarios featuring dematerializing and rematerializing, a real time machine would be a spaceship that moves through all the intervening points between two locations in spacetime. Also explore paradoxes of time travel.
Making Stuff Faster

The Science of Healing follows Dr. Sternberg to a tiny village in Greece, where her personal experience of the power of place in healing inspired the research that led to this program. We join her as she explores ruins of ancient Greek healing temples, and visits cutting edge science labs…
Ancient Computer
Part of the Series: NOVA
In 1900, a storm blew a boatload of sponge divers off course and forced them to take shelter by the tiny Mediterranean island of Antikythera. Diving the next day, they discovered a 2,000 year-old Greek shipwreck. Among the ship's cargo they hauled up was an unimpressive green lump of corroded…

In the rolling hills of Ireland's County Tipperary, a laborer harvesting peat from a dried-up bog spots the remnants of a corpse and stops his machine just in time, revealing a headless torso almost perfectly preserved and stained dark brown by the bog. Archeologists recognize the corpse as one of…
Alien Planets Revealed
Part of the Series: NOVA
It's a golden age for planet hunters: NASA's Kepler mission has identified more than 3,500 potential planets orbiting stars beyond our Sun. Some of them, like a planet called Kepler-22b, might even be able to harbor life. How did we come upon this distant planet? Combining startling animation with input…
Rise of the Drones
Part of the Series: NOVA
Drones. These unmanned flying robots-some as large as jumbo jets, others as small as birds-do things straight out of science fiction. Much of what it takes to get these robotic airplanes to fly, sense, and kill has remained secret. But now, with rare access to drone engineers and those who…
Inexplicable Space
Shoot off into the stars for an investigation of some perplexing aspects of space that science has uncovered in the last half-century. Learn about the mysterious trajectory of the Pioneer spacecraft (known as the "Pioneer anomaly"). Explore two of the longest-standing problems in modern astrophysics: dark matter and dark energy.…
