Language defines us as a species, placing humans head and shoulders above even the most proficient animal communicators.

Look beyond the abstract dates and figures, kings and queens, and battles and wars that make up so many historical accounts.

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.

With this exciting and historically rich six-lecture course, experience for yourself the drama of this dynamic year in medieval history, centered on the landmark Norman Conquest. Taking you from the shores of Scandinavia and France to the battlefields of the English countryside, these lectures will plunge you into a world of fierce Viking warriors, powerful noble families, politically charged marriages, tense succession crises, epic military invasions, and much more.

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."

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.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. 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.

Jazz is a uniquely American art form, one of America's great contributions to not only musical culture, but world culture, with each generation of musicians applying new levels of creativity that take the music in unexpected directions that defy definition, category, and stagnation.

"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.
