Richard Feynman was one of the most brilliant theoretical physicists and original thinkers of the 20th century. He rebuilt the theory of quantum electrodynamics, and it was for this work that he won the Nobel Prize in 1965. In 1981, he gave Horizon a candid interview, talking about many things close to his heart.

In the aftermath of Hiroshima, a group of scientists vowed never to turn knowledge into weapons again, and from that promise, CERN was born. Deep underground, researchers from nations in conflict have worked side by side for decades, driven by curiosity and shared wonder. For 70 years, CERN has stood as an act of hope, a place where collaboration transcends borders, even as the world above grows more divided. Blending poetry, music and rare archival footage of nuclear physicist Robert Oppenheimer with remarkable access to the Large Hadron Collider, the film explores how science, politics and culture collide.

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.

Nuclear energy might be a failed experiment. In over sixty years the technology has not only failed to keep its promise of cheap, clean and safe energy, it also caused major catastrophes and enabled more nuclear weapons while the nuclear waste problem is still not solved.

The double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena.

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.?
