What is that mysterious thing we call charisma? Where does this magnetic quality come from? Why are we so drawn to it? Are people born charismatic - or do they become that way over time? Can charisma be just as much a force for evil as it is for good? Answers to questions like these are just as important now, in the 21st century, as they were during the earliest years of the American republic.

World War II is the defining conflict of the 20th century, one that created a line in the sands of history dividing the pre-war and post-war eras. In this epoch-defining conflict lies another definitive moment: the invasion of a 50-mile stretch of coast in Normandy, France, on June 6, 1944. This battle, also known as D-Day, was the pivot point of the war in Europe. Its success led to a nearly yearlong, bloody campaign that saw the liberation of France, Luxembourg, Belgium, and the Netherlands, followed by the final defeat of Hitler’s Third Reich.

In 10 riveting episodes that feel like a fast-paced thriller, acclaimed World War II historian Edward G. Lengel’s Generals and Geniuses: A History of the Manhattan Project brings the origin of the atomic bomb - and the scientific minds behind it - to vivid life. Did the Manhattan Project, and the remarkable weapon it produced, save millions of lives at the expense of the tens of thousands who died in Hiroshima and Nagasaki? And was there any way to prevent this technology from unleashing the horrors that still hang over us today?

In George Orwell: The Man and the Mind Behind 1984, Professor Michael Shelden will show you how 1984 presents a plausible reality of thought control and totalitarian power that feels contemporary even as it reflects its own time.

It’s not news that women have been denied the same educational and institutional opportunities, resources, and access as men, and that science’s history is often told through the stories of great men, with a few great women making an appearance here and there. But that approach misses the big picture. The history of science isn’t complete without women.

While most of us are familiar with the Underground Railroad, there was much more to the movement than helping individuals escape their bondage. In the eight lectures of The Abolitionists, Professor Kellie Carter Jackson of Wellesley College will bring you along as she traces the history of the fight to end slavery in America, from its relatively quiet origins to the turning point at Harper’s Ferry to the Civil War.

During their eight overlapping years in office, the U.S. president and the U.K. prime minister worked together to promote lower taxes, deregulation, free trade, and an aggressive stance against the Soviet Union. But according to Nicholas Wapshott, the Reagan/Thatcher relationship was much deeper than an alliance of mutual interests.

To be human in today’s world means that you engage in constant linguistic interactions with some form of technology, from your smart phone to your refrigerator. That’s not as new a trend as you might think. Language has shaped - and been shaped by - some of our world’s most significant communication technologies. Our current language bears the marks of millennia of interaction between humans and our technologies, beginning with the very first primitive writing systems and moving into the age of the printing press, the telegraph, and the typewriter.

We might be afraid of lions, tigers, and bears (oh, my!), but much more frequently, our worst foes come without teeth and claws and in teeny, tiny packages. In These Six Things Will Kill You, medical historian Brandy Schillace introduces you to half a dozen deadly forces, often microscopic and invisible, that might be coming for you at this very moment.

Professor Edelstein examines the enduring appeal of Judy Blume’s books. Over seven lessons, you’ll learn how Blume pioneered middle-grade and young adult (YA) literature and helped to make these genres the global sensations they are today. You’ll identify the themes and motifs that run throughout her books, and you’ll review Blume’s books as literary work worthy of analysis. You’ll also see why the very act of questioning (about the existence of God, the persistence of racism, the unwritten rules of suburbia) is so central to Blume’s vision of coming-of-age literature.
