Join scientists as they grab light from across the universe to prove quantum entanglement is real. Einstein called it "spooky action at a distance", but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon two subatomic particles that mirror changes in each other instantaneously over any distance is real. But a few doubts remain. NOVA follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle remaining questions.
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.
In episode one, Helen ventures to the bottom of the temperature scale, revealing how cold has shaped the world around us and why frozen doesn't mean what you might think. She meets the scientists pushing temperature to the very limits of cold, where the normal laws of physics break down and a new world of scientific possibility begins. The extraordinary behaviour of matter at temperatures close to absolute zero is driving the advance of technology, from superconductors to quantum computing.
S1E1 • From Ice to Fire: The Incredible Science of Temperature • 2018 • Physics
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?
