What is kevlar, and why is it so resilient? - Max G. Levy

Explore the chemistry behind what makes kevlar so strong, and how this essential synthetic fiber was invented. -- By 1975, Richard Davis had been shot at close range 192 times. But not only was he completely healthy, each of those bullets were part of a demonstration to sell his new product: the bulletproof vest. So, how does such a light, flexible piece of clothing stop a bullet? The secret was a synthetic fiber material invented a decade earlier. Max G. Levy explores the incredible strength of kevlar. Lesson by Max G. Levy, directed by Vitalii Nebelskyi, and action creative agency.

How to get better at video games, according to babies - Brian Christian

Explore what happened when the AI system Deep Q Networks (DQN) attempted to beat the Atari game Montezuma’s Revenge. -- In 2013, a group of researchers wanted to create an AI system that could beat every Atari game. They developed a system called Deep Q Networks (DQN) and less than two years later, it was superhuman. But there was one notable exception. When playing Montezuma’s Revenge, DQN couldn’t score a single point. What was it that made this game so vexingly difficult for AI? Brian Christian investigates. Lesson by Brian Christian, directed by Gavin Edwards, Movult.
