Imagine a game of dice: if the biggest number rolled is one, two, three, or four, player 1 wins. If the biggest number rolled is five or six, player 2 wins. Who has the best probability of winning the game? Leonardo Barichello explains how probability holds the answer to this seemingly counterintuitive puzzle.

Discover the history and symbolism of Pablo Picasso’s powerful anti-war mural, “Guernica,” rendered in his signature Cubist style.

Uploaded 30-04-19

--

In 1937, in one of the worst civilian casualties of the Spanish Civil War, Fascist forces bombed the village of Guernica in Northern Spain. For Pablo Picasso, the tragedy sparked a frenzied period of work in which he produced a massive anti-war mural, titled “Guernica.” How can we make sense of this overwhelming image, and what makes it a masterpiece of anti-war art? Iseult Gillespie investigates.

Lesson by Iseult Gillespie, directed by Avi Ofer.

The ability to recognize sounds and identify their location is possible thanks to the auditory system. That’s comprised of two main parts: the ear, and the brain. The ear’s task is to convert sound energy into neural signals; the brain’s is to receive and process the information those signals contain. To understand how that works, Douglas L. Oliver follows a sound on its journey into the ear.

Mumbling fantastical gibberish; devouring blocks of cheese in the nude; peeing in places that aren’t toilets; and jumping out of windows. These are all things people have reportedly done while sleepwalking, a behavior that can be dangerous in some cases. It’s estimated that around 18% of people sleepwalk at least once in their lives. So, what exactly is sleepwalking? Emmanuel During investigates.

Lesson by Emmanuel During, directed by Laura Jayne Hodkin.
