  • Notes of a native son: the world according to James Baldwin - Christina Greer
    February 12, 2019

    James Baldwin was an American novelist and social critic whose essays in “Notes of a Native Son” explored race, sex and class distinctions. -- In the 1960s, the FBI amassed almost 2,000 documents in an investigation into one of America’s most celebrated minds. The subject of this inquiry was a writer named James Baldwin, one of the best-selling black authors in the world at the time. What made him loom so large in the imaginations of both the public and the authorities? Christina Greer explores the life and works of James Baldwin.

The exquisite spike-thumb frog (Plectrohyla exquisita) is a charming ambassador for the park’s rich biodiversity and one of 16 different species of amphibians listed as Endangered or Critically Endangered by the IUCN. Some are found nowhere else on Earth and face a growing number of threats. In addition to illegal deforestation and climate change, chytrid fungus—the now infamous disease that has decimated frog populations around the world—was discovered in the park in 2007. Scientist Jonathan Kolby founded the Honduras Amphibian Rescue & Conservation Center (HARCC), an organization that is working to both treat juvenile frogs infected with chytrid fungus and develop a breeding and reintroduction program for several endangered species to guard against extinction. But their efforts to breed exquisite spike-thumb frogs have revealed a puzzling challenge; despite 10 years of intensive field work in the area, scientists have never heard or recorded the species’ mating call—and recordings of these calls can be critical tools when it comes to inspiring frogs to breed in captivity. So, with the help of sound artist Ben Mirin, the team embarked on a quest to record the enigmatic frog’s call and bring its voice back to the lab. What ensues is both a delightful portrait of the process of scientific discovery and an inspiring example of the power of sound as a tool for conservation.

  • What is consciousness? - Michael S. A. Graziano
    February 11, 2019

    Explore the theories of human consciousness and the science of how your brain works to create a conscious experience. -- Patient P.S. suffered a stroke that damaged the right side of her brain, leaving her unaware of everything on her left side. If someone threw a ball at her left side, she might duck. But she wouldn’t have awareness of the ball or know why she ducked. Where does consciousness come from? Michael Graziano explores the question that has vexed scientists and philosophers for centuries. Lesson by Michael S. A. Graziano, directed by TED-Ed.

  • Will there ever be a mile-high skyscraper? - Stefan Al
    February 7, 2019

    Would a mile-high skyscraper ever be possible? Explore the physics behind some of the tallest buildings and megastructures in the world. -- In 1956, architect Frank Lloyd Wright proposed a mile-high skyscraper, a building five times as high as the Eiffel Tower. While this massive tower was never built, today bigger and bigger buildings are going up around the world. How did these impossible ideas turn into architectural opportunities? Stefan Al explains how these megastructures became fixtures of our city skylines. Lesson by Stefan Al, directed by TED-Ed.

  • Tamandua Pup is Getting Bigger - Cincinnati Zoo
    February 6, 2019

    The little tamandua pup is growing fast. It weighed 2.7 pounds this morning, a gain of almost 2 pounds since it was born on 12/20. A type of anteater, the tamandua (pronounced tuh MAN doo wah) is often called a lesser anteater because it is much smaller than its relative, the giant anteater. This interesting animal is at home both in trees and on the ground. The tamandua is most active at night, often nesting during the day in hollow tree trunks. It has small eyes and poor vision but can hear and smell quite well.

  • Why should you read Shakespeare’s “The Tempest”? - Iseult Gillespie
    February 5, 2019

    Explore William Shakespeare’s play “The Tempest”, a story of shipwreck, magic and a fight for power. -- Claps of thunder and flashes of lightning illuminate a swelling sea, as a ship buckles beneath the waves. It is no ordinary storm, but a violent and vengeful tempest, and it sets the stage for Shakespeare’s most enigmatic play. Why does this play still resonate with modern readers? Iseult Gillespie investigates. Lesson by Iseult Gillespie, directed by Héloïse Dorsan Rachet.

  • How one journalist risked her life to hold murderers accountable - Christina Greer
    February 4, 2019

    Ida B. Wells was an investigative journalist, civil rights leader, and anti-lynching advocate who fought for equality and justice. -- In the late 1800’s, lynchings were happening all over the American South, often without any investigation or consequences for the murderers. A young journalist set out to expose the truth about these killings. Her reports shocked the nation, launched her journalism career and a lifelong pursuit of civil rights. Christina Greer details the life of Ida B. Wells and her tireless struggle for justice. Lesson by Christina Greer, directed by Anna Nowakowska.

  • Broadway, Seriously: Crash Course Theater #46
    February 1, 2019

    We're going to Broadway, everybody, and it's not going to be that fun. In fact, it's going to be a very serious experience with lots of powerful social commentary and indictments of life in America in the 1950s. So be prepared to look at the works of Tennessee Williams, Arthur Miller, and Lorraine Hansberry, and to look into the face of chronic illness, racism, and the crushing malaise of American middle class life.
