The story of the groundbreaking scientific discovery that everything is made from atoms.
Jim Al-Khalili shows how investigation into the atom unravelled the mystery of creation.
How studying the atom forced us to rethink the nature of reality itself.
Visiting a hidden location buried beneath the hills of Scotland, Helen experiences some of the most extreme acoustics in the world. Here she learns just how much information can be carried by sound. She discovers how sound has driven the evolution of truly incredible biological systems and complex relationships between creatures that exploit sound for hunting - and escaping from predators. Helen demonstrates how sound waves diffract (bend around objects) and in doing so help us sense danger and locate it. Helen explains how we are not limited to passively detecting sound waves; we can also use them to actively probe the world.

The crosshairs are lined up, a death ray is fired and a planet is vaporized. Sci fi fantasy? Not according to Dr Michio Kaku, who draws up blueprints to show how a real death star might work. The technology could be here sooner than you think!
S1E3 • Physics of the Impossible • 2009 • Physics
We feel it every moment of our lives but for physicists, gravity is the longest running unsolved mystery of the universe. Why do all objects that have mass pull on one another? Cutting-edge theories are proposing unexpected answers.

Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.
Isaac Newton - brilliant rational mathematician or master of the occult? This innovative biography reveals Newton as both a hermit and a tyrant, a heretic and an alchemist. Magical images mix with actors and experts to bring alive Britain's greatest scientific genius in his own words.
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.
