Dig into the history of the elite mercenaries known as condottieri, who were soldiers for hire for Italy's rich and powerful.

--

During the 14th and 15th centuries, mercenaries known as condottieri dominated Italian warfare, profiting from— and encouraging— the region’s intense political rivalries. As rulers competed for power and prestige, their disputes often played out in military conflicts, fought almost entirely by the condottieri. So who were these elite and conniving warriors? Stephanie Honchell Smith investigates.

Examine the empty land theory, which was created by European colonizers in South Africa to support their claims to the region.

--

From the 1650s through the late 1800’s, European colonists descended on South Africa. They sought to claim the region, becoming even more aggressive after discovering the area’s abundant natural resources. To support their claims to the land, the colonizers asserted they were settling in empty land devoid of local people. Was this argument true? Anneliese Mehnert debunks the Empty Land Theory.

Lesson by Anneliese Mehnert, directed by Héloïse Dorsan-Rachet.

Human beings are everywhere. With settlements on every continent, we can be found in the most isolated corners of Earth’s jungles, oceans and tundras. Our impact is so profound, most scientists believe humanity has left a permanent mark on Earth’s geological record. So what would happen if suddenly, every human on Earth disappeared? Dan Kwartler investigates.

Explore what happened after the Big Bang and how the battle between gravity and pressure shaped the structure of our universe.

It’s time for the biggest battle in the Universe: the Big Bang. In one corner is gravity— the force that brings all matter together. In the other is pressure— the force that can push matter away. Over the next several hundred thousand years, these two contenders will be wrestling for the fate of the Universe. But what are these powers fighting over? Fabio Pacucci digs into this historic matchup.

Uploaded 04-02-20

Can someone’s political identity actually affect their ability to process information? The answer lies in a cognitive phenomenon known as partisanship. While identifying with social groups is an essential and healthy part of life, it can become a problem when the group’s beliefs are at odds with reality. So how can we recognize and combat partisanship? Jay Van Bavel shares helpful strategies.

In an engaging and personal talk -- with cameo appearances from his grandmother and Rosa Parks -- human rights lawyer Bryan Stevenson shares some hard truths about America's justice system, starting with a massive imbalance along racial lines: a third of the country's black male population has been incarcerated at some point in their lives. These issues, which are wrapped up in America's unexamined history, are rarely talked about with this level of candor, insight and persuasiveness.

The prisoner strapped under a descending pendulum blade. A raven who refuses to leave the narrator’s chamber. A beating heart buried under the floorboards. Poe’s macabre and innovative stories of gothic horror have left a timeless mark on literature. But just what is it that makes Edgar Allan Poe one of the greatest American authors?
