When we look at the world at the tiniest scales in the subatomic realm, things get weird—very weird. Welcome to the quantum universe, where particles can spin in two directions at once, observing something changes it, and something on one side of the galaxy can instantly affect something on the other, as if the space between them didn’t exist. Buckle up for a wild ride through the discoveries that proved all of this to be true and paved the way for the digital technologies we enjoy today—and the powerful quantum sensors and computers of tomorrow.

The enigmatic nature of the Nixon presidency combined comparatively progressive legislative initiatives with a flagrant abuse of presidential power and the public trust. His achievements in expanding peaceful relations with China and the Soviet Union stand in stark contrast with his continuation of the war in Vietnam. Finally brought down by scandal and duplicity, his administration did much to erode the citizenry's faith in government.

Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the internet, and 'big data,' the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty? From the glitz of casinos and TV game shows to the life-and-death stakes of storm forecasts and the flaws of opinion polls that can swing an election, 'Prediction by the Numbers' explores stories of statistics in action. Yet advances in machine learning and big data models that increasingly rule our lives are also posing big, disturbing questions. How much should we trust predictions made by algorithms when we don't understand how they arrive at them? And how far ahead can we really forecast?

How big is the universe? If it began with the Big Bang, will it also have an end? Is there life beyond our planet? Questions like these inspired the launch of Voyager I in 1977 and have driven innovative space research and exploration ever since. Trace ground-breaking discoveries that have transformed our picture of the universe, from an age when we knew of no planets beyond our solar system, to today, when we have evidence of thousands and estimate trillions more. And follow the teams trying to solve two of the biggest mysteries in cosmology today: What are dark matter and dark energy?

He went off to war an unknown soldier and returned a beloved national hero. Often dismissed as a "do-nothing" president and a good-natured bumbler, Dwight D. Eisenhower -- the last American president to be born in the 19th century -- was actually a skillful politician, a tough Cold War warrior, and one of America's most misunderstood and unappreciated presidents. Two-part documentary from American Experience.

Four times governor of Alabama, four times a candidate for president, he was feared as a racist demagogue and admired as a politician who spoke his mind. A lightning rod for controversy, Wallace both reflected and provoked tensions in American society over more than four decades. This film traces the rise of the firebrand politician from his roots in rural Alabama to the assassination attempt that suddenly transformed him.
