Throwing a curveball is one of the most difficult pitches in baseball. Bill Lee, a former pitcher for the Red Sox, explains how important it is to consider physics when trying to throw a curveball. Listen to learn how objects travel through space and how gravity affects a curveball.
Gravity keeps our feet on the ground, it creates a curve ball, and it can also be used to find new planets. The star at the center of our solar system maintains life on Earth and its gravitational pull creates the orbit of planets. But our sun is just one of many stars in an ever expanding universe. Alpha Centauri is the closest star system to our solar system and new technology is allowing us to better understand our neighbor. Observations of Alpha Centauri date back to 1592, but it wasn’t until 2012 that astronomers in Chile were able to identify a planet orbiting one of the stars in Alpha Centauri because of its gravitational wobble. Listen to learn more about the properties and potential of this new planet.
Even though it is the weakest of all forces, gravity is why we exist. Gravity keeps the earth, moon, and sun in orbit. It keeps us on the ground instead of floating in space. Listen to hear how gravity affects the velocity in rockets, the shapes of planets, the trajectories of baseballs, and even the strength of the human leg bones.
In 1741, New York City was shaken by an uprising led by African slaves. New York was a British colony and had a very large slave population.

Rankine’s initial response to the question, “Why might a person choose to go blonde?” was that people simply wanted to lighten their hair. But she soon wondered if there might be more to it. To find out, she interviewed and photographed women of all skin tones who chose to dye their hair blonde. The result was a gallery exhibit entitled “Stamped.” Listen to hear about what the artist discovered when she explored the connections between race, identity, and blondeness.
In 1791, in what is now known as Haiti, Toussaint Louverture led a revolt against slavery that led to independence from France. In a time of many other attempted revolts, this was perhaps the most famous and successful. It went on for many years until 1804 the independent state of Haiti was formed. Louverture is interesting in that he is a complex and contradictory historical figure.

The novel is set in World War I era Italy and tells the story of an American ambulance driver who falls in love with an English nurse. Although unmarried, the two conceive a baby and escape together to Switzerland, where tragedy strikes: the woman dies in childbirth.

Listen to hear why Hemingway wrote so many endings and why, ultimately, he chose to stick with his original, heart-wrenching conclusion.
Cells are used in research to make scientific discoveries. A certain set of cells are among the most widely used in biomedical research worldwide. These HeLa cells have been used to research almost every disease and have played an important role in many scientific breakthroughs including the development of the polio vaccine. The cells come from a woman named Henrietta Lacks who has been mentioned in more than 70,000 published scientific papers. Listen to hear more about how these cells are used and the issues of privacy with her family.
Henry Clay is an overlooked and very important 19th century American politician. As a Senator, House Speaker, and Secretary of State, he helped shape antebellum America’s growth and, some say, helped hold off civil war for decades. He is credited with doing this through compromises that enabled America’s territorial expansion without allowing the issue of slavery to be a barrier. In this audio story, an historian tells the story of the Missouri Compromise, brokered by Clay, and looks at his legacy and relevance in today’s politics, where compromise is often seen as a sign of weakness.
Herman Melville’s classic American novel “Moby-Dick” tells the story of whaling captain Ahab’s quest to kill the white whale Moby-Dick. This somewhat simplistic plot retelling misses the thematic and historical undertones of this massive novel. The novel was a critical and commercial failure when it was released in 1851 but experienced a resurgence after World War I. Listen to learn about the writing of “Moby-Dick” and how Melville was influenced by the works of Nathaniel Hawthorne and Shakespeare, as well as the tensions of pre-Civil War America.
Serving in the military during a war can lead men and women to experience events that affect them for the rest of their lives. Louis Zamperini was one example. Laura Hillenbrand wrote a best-selling novel, “Unbroken”, which tells his story. It is set in World War II where Zamperini fought for survival on a life raft in the Pacific Ocean, was held as a POW by Japan, and later struggled in civilian life to deal with his war memories. This story, told at the time of his death in 2014, is a previous interview with Hillenbrand, where she recounts Zamperini’s story of survival during the war and his struggle to find closure in the decades following his return home. Listen to hear this extraordinary story of courage, despair and redemption.

Middle school history teachers have different strategies for how to engage students in learning. One way is to use topics that kids already find interesting and connect them to historical events. One example is insects. A children’s writer featured in this story, uses stories involving bugs to teach important events in history such as the Louisiana Purchase and Lewis and Clark. Her belief is that through topics that appeal to kids’ love of things gross and skeevy, important learning can happen.

Listen to learn how snow is formed and why it exists in some places but not others.
The Gross Domestic Product, or GDP, measures the worth of all the goods and services produced in a country. Knowing the GDP helps countries monitor how strong or weak their economies are. When the GDP gets bigger, conventional wisdom says that the economy is healthy and growing, while a shrinking GDP means that something is wrong. The GDP provides a way to see the fluctuations in a nation’s economy over time. But the usefulness of the GDP is limited. Listen to this story to find out why.

It also discusses similarities to methods used in Guantanamo Bay Naval Base in Cuba, at the United States’ detention camp. Listen to hear how the institutionalizing of the Inquisition hundreds of years ago is linked to persecution today.
This story explores an important economic question: When a kid loses a tooth, how much should the tooth fairy pay?
