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.

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.

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?

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.

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.
