Redefining Reality

Philosophers have long puzzled over the nature of space, time, and matter. These inquiries led to the flowering of physics with the Scientific Revolution in the 17th century. Since then, the spectacular success of modern physics might appear to have made philosophy irrelevant. But new theories have created a new range of philosophical concerns: What is the shape of space? Is time travel possible? Is there a grand unified theory that unites all of physics? 

Grasp the important ideas that have served as the backbone of philosophy across the ages with this extraordinary 60-lecture series. This is your opportunity to explore the enormous range of philosophical perspectives and ponder the most important and enduring of human questions-without spending your life poring over dense philosophical texts.

What is reality? Ask yourself whether you can actually know the answer, much less be sure that you can know it, and you've begun to grapple with the metaphysical and epistemological quandaries that have occupied, teased, and tormented modern philosophy's greatest intellects since the dawn of modern science and a century before the Enlightenment.

For most of its 5,000-year existence, China has been the largest, most populous, wealthiest, and mightiest nation on Earth.

Over the span of 48 lectures, four experienced lawyers and teachers recreate key parts of the first-year law student experience, introducing you to main areas of law most every beginning student studies. Enriched with famous cases from the annals of American law and powerful arguments by some of history's most successful lawyers, these lectures offer access to an often intimidating, surprisingly accessible, and civically important field.

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.

We have all pondered seemingly unanswerably but significant questions about our existence - the biggest of all being, "Why are we here?" Philosophy has developed over millennia to help us grapple with these essential intangibles. There is no better way to study the big questions in philosophy than to compare how the world's greatest minds have analyzed these questions, defined the terms, and then reasoned out potential solutions. Once you've compared the arguments, the final step is always deciding for yourself whether you find an explanation convincing.

Time rules our lives, woven into the very fabric of the universe-from the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day. Nothing so pervades our existence and yet is so difficult to explain. But now, in a series of 24 riveting lectures, you can grasp exactly why - as you take a mind-expanding journey through the past, present, and future, guided by a noted author and scientist.

The deep-seated origins and wide-reaching lessons of ancient myths built the foundation for our modern legacies. Explore the mythologies of Europe, the Americas, Asia, Africa, and the Middle East. Learn what makes these stories so important, distinctive, and able to withstand the test of time. Discover how, despite geographical implausibilities, many myths from across the oceans share themes, morals, and archetypes.

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 a book that took eight years to research and write, leading Bible scholar Bart D. Ehrman explores how an apocalyptic prophet from the backwaters of rural Galilee crucified for crimes against the state came to be thought of as equal with the one God Almighty Creator of all things. Ehrman sketches Jesus's transformation from a human prophet to the Son of God exalted to divine status at his resurrection. Only when some of Jesus's followers had visions of him after his death - alive again - did anyone come to think that he, the prophet from Galilee, had become God.

This mind-bending tour of metaphysics applies philosophy to the forefront of today's knowledge. Over the course of 24 fascinating lectures, Professor Johnson thinks through the big questions about humans and the universe: The relationship between the mind and the brain, how consciousness emerges from neurochemical processes, the existence of God, human free will, the possibility of time travel, and whether we live in a multiverse or even a computer simulation.

Would you like to know how the universe works? Scientists have been asking that question for a long time and have found that many of the answers can be found in the study of particle physics, the field that focuses on those impossibly tiny particles with unbelievably strange names - the hadrons and leptons, baryons and mesons, muons and gluons - so mystifying to the rest of us.

Cutting-edge research on the brain's interaction with the body shows that health is directly impacted by our social environments, socioeconomic status, culture, behaviors, relationships, psychological states, and habits of mind, among many factors. Mind-body medicine-working in partnership with traditional medical practice-uses a large range of psychological, physical, and behavioral treatments in a model of health care that aims to treat the whole human being.
