No skill is more important in today's world than being able to think about, understand, and act on information in an effective and responsible way.

But because misinformation out there has increased as well, critical thinking is more important than ever. These 24 rewarding lectures equip you with the knowledge and techniques you need to become a savvier, sharper critical thinker in your professional and personal life.

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.

"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.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

Your nervous system is you. All the thoughts, perceptions, moods, passions, and dreams that make you an active, sentient being are the work of this amazing network of cells. For many centuries, people knew this was true. But no one was sure how it happened. Now, thanks to the exciting new field of neuroscience, we can chart the workings of the brain and the rest of the nervous system in remarkable detail to explain how neurons, synapses, neurotransmitters, and other biological processes produce all the experiences of everyday life, in every stage of life.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity.

Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

To understand the roots of personality is to understand motivations and influences that shape behavior, which in turn reflect how you deal with the opportunities and challenges of everyday life. That's the focus of these exciting 24 lectures, in which you examine the differences in people's personalities, where these differences come from, and how they shape our lives. Drawing on information gleaned from psychology, neuroscience, and genetics, Professor Leary opens the door to understanding how personality works and why.

As recently as 1990, it seemed plausible that the solar system was a unique phenomenon in our galaxy. Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.

Austen wrote, 'I am going to take a heroine whom no-one but myself will much like' and thus introduces the handsome, clever, rich - and flawed, Emma Woodhouse. Emma is perfectly content with her life and sees no need for either love or marriage; nothing however delights her more than matchmaking her fellow residents of Highbury. But when she ignores the warnings of her good friend Mr. Knightley and attempts to arrange a suitable match for her protegee Harriet Smith, her carefully laid plans soon unravel and have consequences that she never expected.

Charles Darwin's theory of organic evolution-the idea that life on earth is the product of purely natural causes, not the hand of God-set off shock waves that continue to reverberate through Western society, and especially the United States. What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? These 12 eye-opening lectures are an examination of the varied elements that so often make this science the object of strong sentiments and heated debate.

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.

It is an age of exploration. Jedi travel the galaxy, expanding their understanding of the Force and all the worlds and beings connected by it.

On the close-orbiting planets of Eiram and E’ronoh, the growing pains of a galaxy with limited resources but unlimited ambition are felt keenly. The two worlds’ hatred for each other has fueled half a decade of escalating conflict and now threatens to consume surrounding systems.

Since its rise to the highest ranks of power in Renaissance Europe, the Borgia family has developed a scandalous reputation. While they were indeed ostentatious, calculating, worldly, cruel - and even, occasionally, murderous - you may be surprised to find that the Borgias were not terribly different from other powerful and ambitious families of their day. So why has history set them apart as one of the most corrupt and reviled families in history?

Why are we scared of ghosts, zombies, vampires, demons, and monsters, when we know they are not real? Why do dark attics give us the creeps? How do writers and directors know exactly what anxieties to tap into, so that we break out in goosebumps, cover our eyes, and cringe?

The history of the Boston Tea Party is a hidden one. Why? Since it was a clandestine operation, all sorts of rumors and legends grew up around the event—many collected decades after the American Revolution had ended. At its core, however, the night of December 16, 1773, when colonials dumped tea from British ships into Boston Harbor, was more than a fight over tea and taxes. It was a struggle over the very nature of democracy and self-governance.

The stuff of conspiracy theories makes for great, entertaining stories in movies, books, and television. And there is no shortage of subjects: from who really killed JFK to the truth behind 9/11. And then, there are subjects from alien invasions to the Moon landing was simulated - theories that are truly out of this world, which according to some, is flat. Many of these crazy concepts have jumped off the pages or screens to become so pervasive in our culture that thousands - even millions - subscribe to them as reality.

New religious movements aren’t earthquakes - they’re not generated by blind natural forces, and they’re not inevitable. Social and spiritual change requires a catalyst to set it in motion. And in the case of Islam, that catalyst has a name: Muhammad. He was a charismatic individual, born of the existing culture of sixth-century Arabia and yet somehow alienated from it. He drew on existing religious ideas in radically new ways that would change his world - and ours - forever. Join Maria Dakake of George Mason University for a riveting exploration of Islam’s founding prophet.

Every year has its share of notable events, but some years seem to capture the essence of a decade in a handful of months. The year 1954 is one such year. It began in January with a celebrity marriage heard round the world and then progressed through a series of major political, social, and cultural milestones that would echo through the next several decades. The years following World War II were a time of increased wealth and confidence, years that saw the rise of a solid, increasingly powerful middle class in America.
