    Why did people don powdered wigs? - Stephanie Honchell Smith

    Trace the rise and fall of the powdered wig fashion craze, from King Louis XIII to the French Revolution in the 18th century. -- Wigs date at least as far back as ancient Egypt, where well-regarded hairdressers crafted them into intricate styles. And under certain ancient Roman dynasties, women’s wigs became particularly ornate. Yet it wasn’t until Louis XIII unveiled a magnificent mane in the 17th century that big wigs truly began booming. Stephanie Honchell Smith details the rise and fall of the bewigged fashion craze. Lesson by Stephanie Honchell Smith, directed by Patrick Smith.

    How close are we to fueling the world with nuclear fusion? - George Zaidan

    Explore the possibility of nuclear fusion technology to create limitless, on-demand energy with almost no emissions. -- Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But that “lost” mass doesn’t disappear — it’s converted to energy ... a lot of energy. So, can we harness this energy to power the world? George Zaidan investigates. Lesson by George Zaidan, directed by Igor Ćorić, Artrake Studio.
