Explore the successes and failures of FDR’s New Deal, a set of legislation during the Great Depression which aimed to save the US economy.

Uploaded 17-06-21

--

In 1932, one in four Americans was unemployed, marking the highest unemployment rate in the country’s history. The Democratic presidential candidate Franklin D. Roosevelt promised a New Deal— a comprehensive set of legislation to support struggling citizens and put the country back to work. Meg Jacobs digs into the policies of this bold campaign and how it didn’t fully live up to its promises.

Lesson by Meg Jacobs, directed by Anton Bogaty.

Dig into the phenomenon of face pareidolia, which is the tendency of our brains to see faces in everyday objects.

--

Imagine opening a bag of chips, only to find Santa Claus looking back at you. Or turning a corner to see a building smiling at you. Humans see faces in all kinds of mundane objects, but these faces aren’t real— they're illusions due to a phenomenon known as face pareidolia. So why exactly does this happen, and how far does this distortion go? Susan G. Wardle explores why we see illusory faces.

Lesson by Susan G. Wardle, directed by Oksana Kurmaz.

Get to know 3 factors that can help you identify pseudoscience, and find out how it differs from actual science.

--

Pseudoscience is a set of theories, methods, and assumptions that appear scientific, but aren’t. In the worst cases, pseudoscience practitioners encourage this confusion to exploit people. But even when it's well-intentioned, pseudoscience can still prevent people from getting the help they need. So, how can you tell what’s science and what’s pseudoscience? Siska De Baerdemaeker investigates.

Discover the adaptation of the pharyngeal jaw, a secondary set of jaws that allow fish to capture and eat their prey at the same time.

Uploaded 29-06-21

--

After stalking a cuttlefish, a moray eel finally pounces. As the eel snags the mollusk in its teeth, its prey struggles to escape. But before it can wiggle away, a second set of teeth lunge from the eel’s throat. This adaptation is called a pharyngeal jaw, and is one of the most common adaptations under the sea. Darien Satterfield shares how this incredible skeletal mechanism works.

Lesson by Darien Satterfield, directed by Zack Williams.
