The principles of the French Revolution remain the only possible basis for a just society - even if, after more than 200 years, they are more contested than ever before. In A New World Begins, Jeremy D. Popkin offers a riveting account of the revolution that puts the listener in the thick of the debates and the violence that led to the overthrow of the monarchy and the establishment of a new society.

Language defines us as a species, placing humans head and shoulders above even the most proficient animal communicators. But it also beguiles us with its endless mysteries, allowing us to ponder why different languages emerged, why there isn't simply a single language, how languages change over time and whether that's good or bad, and how languages die out and become extinct.

In Understanding Cognitive Biases, you will learn how to recognize biases for what they are, counteract them when necessary, and even use them to your advantage in some instances. In 24 fascinating lectures, Dr. Alexander B. Swan uses examples from psychology experiments, history, politics, movies, TV, comics, social media, and more to illustrate dozens of cognitive biases that affect us all.

"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics.

Noted Japan expert Professor Mark J. Ravina of the University of Texas at Austin covers the politics, economics, and culture of the island nation since World War II - a conflict that saw the end of Japan’s dream of regional conquest, which Professor Ravina calls Empire 1.0. The country’s postwar leaders radically changed course, renouncing a strong military to pursue Empire 2.0 - Japan as an economic colossus.

Between 1861 and 1865, the clash of the greatest armies the Western hemisphere had ever seen turned small towns, little-known streams, and obscure meadows in the American countryside into names we will always remember. In those great battles, those streams ran red with blood-and the United States was truly born.

Grammar! For many of us, the word triggers memories of finger-wagging schoolteachers, and of wrestling with the ambiguous and complicated rules of using formal language. But what is grammar? In fact, it's the integral basis of how we speak and write. As such, a refined awareness of grammar opens a world of possibilities for both your pleasure in the English language and your skill in using it, in both speech and the written word.

Eating is an indispensable human activity. As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man."

Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves. Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes "backwards" sometimes; how to turn the tide in the fight against AIDS.

What is our species' greatest invention? Medicine, computers, space travel? Not even close. The innovation that underlies each of our past achievements and those we still aspire to is language. Language is the ultimate invention of Homo sapiens - one that has allowed us to change the physical and social world around us in every conceivable way, and an invention that has fundamentally changed us, as well.
