The ancient world has influenced our customs and religious beliefs, our laws, and the form of our governments. It has taught us when and how we make war or pursue peace. It has shaped the buildings we live and work in and the art we hang on our walls. It has given us the calendar that organizes our year and has left its mark on the games we play.Includes a PDF course guidebook that contains 362 pages.

    And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of approaching and grappling with some of the universe's most pressing and vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered? What are some of the next avenues of exploration for today's chemists, physicists, biologists, and astronomers? Pondering the answers to these and other questions is a great way to appreciate the grandeur and complexity of the world around you, better understand and discuss news and developments in science, and spark further interest in some of science's many exciting areas of study. "We know a lot about the universe. But there's even more that we don't know,"says astrophysicist and Professor Neil deGrasse Tyson, director of the Hayden Planetarium, an award-winning lecturer, and one of the world's foremost experts on the secrets of the universe. And his course The Inexplicable Universe: Unsolved Mysteries is the perfect gateway into this mind-bending and eye-opening subject. Each of these six self-contained lectures is a marvelous journey to the frontiers of the known (and unknown) universe and introduces you to tantalizing questions being addressed by the world's top scientists. Undeniably engaging and fascinating, this lecture series is a wonderful entrée to scientific pursuits that lie at the very heart of the history and nature of our universe. An Informed Scientific Conversation Central to The Inexplicable Universe is the way it takes you deep into hidden layers of the universe in a manner that is extremely accessible. Rather than a stern lecture given before a podium complete with confusing mathematics, Professor Tyson's lectures have the feel of an informed conversation that manages to be both thorough and easy to grasp. With each of the inexplicable mysteries he lays bare for you, Professor Tyson introduces you to the history behind it, lays out the science that has helped us grasp it, explains what researchers have discovered to date, and reveals what we have yet to discover. And while the topics explore subjects in everything from quantum mechanics to cosmology to string theory, you'll never feel overwhelmed by what you're learning. In fact, you're more likely to find yourself intrigued by just how much we know-and curious about what the near future will possibly reveal. Explore Fascinating Territory So what territory will you chart in this course? Here are some of the inexplicable ideas you'll investigate in these lectures. Neutrinos: Discovered in 1956, these fast-moving, ghostlike particles are made in abundance in the sun's core. They hardly interact with matter; it takes a light-year's worth of lead (5.8 trillion miles) to stop a neutrino. Not only that, but 65 billion neutrinos pass through every centimeter of your body that's facing the sun every second of every day. String theory: This astounding theory offers the hope of unifying all the particles and forces of physics. In the past several decades since the dawn of string theory, it's been imagined that all the fundamental particles we see and measure are just the manifestation in our dimension of strings vibrating in higher dimensions and at different frequencies. Quantum foam: This idea posits that when the fabric of space and time is so tightly curved on itself, space-time is less a smooth curve and more like the froth on a latte. In this state of matter and energy, quantum fluctuations can spawn entire universes, each with slightly different laws of physics within them! In addition, you'll also get a peek at what it would be like to travel through a black hole, ponder the possibility that life on Earth originated in debris from Mars, probe the supposed existence of multiple universes, and even imagine the possible end of the universe itself. A One-on-One Chat with a Renowned Science Educator Professor Tyson is renowned throughout the scientific community and the media for his vast knowledge, his penetrating insights, and his amazing ability to make even the most intimidating areas of science accessible, engaging, and-most of all-enjoyable. He brings the same inviting tone and sharp intellect to The Inexplicable Universe as he does to his range of media appearances on popular television programs. Due to its unique subject matter The Inexplicable Universe takes a highly visual approach. Many of the fascinating subjects in the course, such as black holes, string theory, and multiple universes are best demonstrated visually and Professor Tyson's lectures feature expertly crafted computer animations, explanatory diagrams, high resolution photographs, and other instructive visual elements. In order to better explain to you some of the grand, intricate ideas being discussed, Professor Tyson personally interacts with many of these animations and graphics using greenscreen technology. Please note that, due to the highly visual nature of The Inexplicable Universe, the course does not come with a guidebook. We did not believe a simple book could adequately convey the information in the course, and rather than make a guidebook that did not do the course justice, we decided to not offer one. However, we believe that you will be very excited by how we produced this course and will find it to be an enriching and fulfilling experience in your educational journey.

    And, though the emerging Orthodox Church eventually condemned Gnosticism as heretical, the church formed many of its most central doctrines (such as original sin, the Immaculate Conception, and even the concept of heresy) in response to Gnostic ideas.This fascinating 24-lecture course is a richly detailed guide to the theology, sacred writings, rituals, and outstanding human figures of the Gnostic movements. What we call "Gnosticism" comprised a number of related religious ideologies and movements, all of which sought "gnosis," or immediate, direct, and intimate knowledge of God. The Gnostics had many scriptures, but unlike the holy texts of other religions, Gnostic scriptures were often modified over time. Gnostic cosmology was extraordinarily intricate and multidimensional, but religious myth was simply a means to the ultimate end of gnosis.Follow Gnostic ideology and its vivid impact on Western thought through the centuries, from its role in early religions and its re-emergence in medieval spirituality to its remarkable traces in modern popular culture, from science fiction novels like Blade Runner to Hollywood films like The Matrix. In delving into the paths of gnosis, you'll discover a compelling, alternative current of religious practice in the West, and reveal Gnostic influence resonating in Western spirituality even in the present day.

    A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with nature’s most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.At the end of the seventeenth century—an age of religious wars, plague, and the Great Fire of London—when most people saw the world as falling apart, these earliest scientists saw a world of perfect order. They declared that, chaotic as it looked, the universe was in fact as intricate and perfectly regulated as a clock. This was the tail end of Shakespeare’s century, when the natural land the supernatural still twined around each other. Disease was a punishment ordained by God, astronomy had not yet broken free from astrology, and the sky was filled with omens. It was a time when little was known and everything was new. These brilliant, ambitious, curious men believed in angels, alchemy, and the devil, and they also believed that the universe followed precise, mathematical laws—-a contradiction that tormented them and changed the course of history.The Clockwork Universe is the fascinating and compelling story of the bewildered geniuses of the Royal Society, the men who made the modern world.

    Now - with the technological advances of modern archaeology and a new perspective on world history - we are finally able to piece together their compelling true stories. In Ancient Civilizations of North America, Professor Edwin Barnhart, Director of the Maya Exploration Center, will open your eyes to a fascinating world you never knew existed - even though you've been living right next to it, or even on top of it, for as long as you've been on the continent.The peoples of ancient North America were exceptionally knowledgeable about their environment, but their intellectual and artistic curiosity went much beyond the immediate need for food and safety. Beginning thousands of years ago, and without benefit of written language, native peoples became mathematicians, construction and soil engineers, astronomers, urban planners, and more. They developed thriving cities, extensive trade routes, canals to bring water to the desert, and earthworks we still marvel over today.In 24 exciting lectures, you'll learn about the vibrant cities of Poverty Point, the first city in North America, built about 3,500 years ago, and Cahokia, the largest city of ancient North America. You'll explore the many ways in which the Chacoan environment provided cultural and religious focus for peoples of the southwest. And you'll learn about the Iroquoian source of some of our most basic "American" values.
