PBS' premier science series helps viewers of all ages explore the science behind the headlines. Along the way, NOVA demystifies science and technology, and highlights the people involved in scientific pursuits.

How big is the universe? What is it made of? Are we alone? Questions like these have inspired amazing discoveries that have transformed our understanding of the universe since the 1970s, shedding light on everything from exoplanets to black holes to the mysterious dark matter and energy that rule the cosmos. And closer to home, quantum physicists have discovered the weird laws that govern the subatomic world, unlocking amazing technologies – from the smart phone in your pocket to powerful new quantum computers taking shape in labs today.

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.

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.

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?

Deep in the forests of Uganda, millions of grasshoppers gather to mate in devastating swarms. A group of young men set up a strange contraption at the edge of the crop fields, with customised generators, large quantities of light bulbs, barrels and sheet metal. They can then begin harvesting the grasshoppers, a prized delicacy among city dwellers.

What is quantum physics? What are its applications? Will we ever fully grasp this astonishing revolution in knowledge that reshuffles the deck of modern science? A pedagogical overview of a scientific superstar that is still far from having revealed all its secrets.

We live in an age when technological innovation seems to be limitlessly soaring. But for all the satisfying speed with which our gadgets have improved, many of them share a frustrating weakness: the batteries. Though they have improved in last century, batteries remain finicky, bulky, expensive, toxic, and maddeningly short-lived. The quest is on for a "super battery," and the stakes in this hunt are much higher than the phone in your pocket. With climate change looming, electric cars and renewable energy sources like wind and solar power could hold keys to a greener future...if we can engineer the perfect battery. Join host David Pogue as he explores the hidden world of energy storage, from the power-and danger-of the lithium-ion batteries we use today, to the bold innovations that could one day charge our world.
