What does quantum mechanics tell us about our world -- or are there many worlds due to probability waves? How does the general theory of relativity mesh with quantum mechanics? If you've wished you understood quantum mechanics (or at least grasped the basics) physicist Brian Greene can help!

It is hard to imagine a sky without an airplane in it. But David McCullough takes us back to the first days of aviation. We learn about the Wright Brothers, not only through their achievements, but by discovering who they were as people and the early family influences that shaped their characters.

Meet Nikola Tesla, the genius engineer and tireless inventor whose technology revolutionized the electrical age of the 20th century. Although eclipsed in fame by Edison and Marconi, it was Tesla's vision that paved the way for today's wireless world. His fertile but undisciplined imagination was the source of his genius but also his downfall, as the image of Tesla as a "mad scientist" came to overshadow his reputation as a brilliant innovator.

Caught up in the race to discover the atom’s internal parts — and learn how they fit together — a young British physicist, Harry Moseley, uses newly discovered X-rays to put the Periodic Table in a whole new light. And a young American chemist named Glenn Seaborg creates a new element — plutonium — that changes the world forever, unleashing a force of unimaginable destructive power: the atomic bomb.

It's called the speed limit of the universe. Einstein blew all of our minds when he worked out the Theory of Relativity, and showed that space and time were malleable substances. He also theorized that we as humans can never travel faster than the speed of light, which leaves the stars and other galaxies almost impossibly out of our reach. But the dreams of Star Wars and Star Trek are not dead. In fact, there could be ways to travel faster than the speed of light - and some of them are already being tested in labs around the world.

In this extraordinary documentary we are going to witness very different kinds and situations of snowing: from howling blizzards to the gentlest and loveliest of weather events, from huge handkerchiefs quietly falling to the needle-sharp attack of hard, heavy grains. Snow - what is it really? How is it created - naturally and artificially? Thanks to CGI and new camera techniques we can actually see this process for the first time and listen to the incredible, inaudible music of snowfall, of myriads of tiny crystals touching and rolling and settling. Each snowflake is unique and bears more secrets than we could imagine. Did you know that different kinds of music influence the crystallization process and the shape of snowflakes? And have you ever imagined that we would be able to produce artificial snow that melts at 30 degrees Celsius? With this in mind: just let it snow!

Particles come in pairs, which is why there should be an equal amount of matter and antimatter in the universe. Yet, scientists have not been able to detect any in the visible universe. Where is this missing antimatter?
How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud details the history of atomic theory.?
