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.

Join Brian Greene on a wild ride into the weird realm of quantum physics, which governs the universe on the tiniest of scales. Greene brings quantum mechanics to life in a nightclub like no other, where objects pop in and out of existence, and things over here can affect others over there, instantaneously and without anything crossing the space between them.

This documentary presents the story of Nikola Tesla, the great scientist, visionary, and inventor who gave the world alternating current electricity, as well as being the father of radio. The film tells the story of this man's astonishing genius, his visions and inventions. Tesla's own scientific and autobiographical writings, as well as archival photographs and re-enactments are used to tell the story. A native of Austro-Hungary, Tesla came to America in 1884. Working first with Edison, the two inventors fell out over Edison's insistence on using direct current. Tesla took his alternating current vision to Westinghouse. His New York address was renowned for the bolts of lightning emanating from it, as Tesla worked to unlock the secrets of energy and electricity. His quest took him to Colorado. The film follows Tesla's exploits and eccentricities, which made him a darling of the press. Included is the well-known and touching story of his devotion to a certain white pigeon. Largely forgotten today in spite of the great debt the modern world owes him, the film pays tribute to this overlooked genius.

One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion?
Atoms are very weird. Wrapping your head around exactly how weird, is close to impossible – how can you describe something that is SO removed from humans experience? But then again, they kind of make up everything, so let us try anyways.
