Published 150 years ago, Charles Darwin's On the Origin of Species - the text that introduced the world to natural selection - is among a handful of books that have changed the world. But the route to that status has been surprisingly circuitous and uncertain. Now, in 24 absorbing lectures by an award-winning teacher, you'll learn the remarkable story of Darwin's ideas, how scientists and religious leaders reacted to them, and the sea change in human thought that resulted.

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.

The landscape of cancer treatment and prevention is a vastly different place than it was even a decade ago. Thanks to a relatively new focus on molecular medicine, researchers are gaining a deeper understanding of the mechanisms involved in the disease, poising them on the brink of huge breakthroughs. What Science Knows About Cancer reports from the front lines of the war on cancer with a clear and scientifically precise - yet thoroughly accessible - guide to how the disease develops, thrives, and can potentially be conquered.

Where do we come from? How did our ancestors settle this planet? How did the great historic civilizations of the world develop? How does a past so shadowy that it has to be painstakingly reconstructed from fragmentary, largely unwritten records nonetheless make us who and what we are?

These 36 lectures bring you the answers that the latest scientific and archaeological research and theorizing suggest about human origins, how populations developed, and the ways in which civilizations spread throughout the globe.

Imagine a region in space where the force of gravity is so strong that nothing - not even light - can escape. This phenomenon is a black hole: one of the most exotic, mind-boggling, and profound subjects in astrophysics. Nearly everyone has heard of black holes, but few people outside of complex scientific fields understand their true nature and their implications for our universe. No movie, novel, or other fictional treatment of black holes matches Professor Filippenko’s absorbing presentation of the actual science behind these amazing objects.

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.

The year is 8000 B.C. A man wanders across a field of prairie grasses in search of edible berries and roots and wild game to feed his family. As he walks, the tips of the grasses brush against him, releasing seeds. He collects a few of these seeds and brings them back to his camp. Later, he notices that when they fall on earth, they begin to sprout, and a new plant grows. In small moments like these, the path of Homo sapiens is changed forever.

Science is humanity's greatest achievement. It ranges from the study of the universe itself to the smallest particles of matter contained within it - and everything in between. If you want to better understand our physical world, as most of us do, gaining a basic understanding of science itself is profoundly important - yet many are intimidated by the breathtaking scope of such an endeavor. Now an award-winning science teacher has taken out the intimidation, harnessing that breathtaking scope into a series of 60 exciting, comprehensive, and accessible lectures.

Trying to understand our human origins has always been a fundamental part of who we are. Today, with the help of dramatic archaeological discoveries and groundbreaking advancements in technology and scientific understanding, we are closer than we've ever been to learning the true story. In recent decades, it has been the science of paleoanthropology that has led the investigation, helping us make sense of this controversial subject and providing us with a richer understanding of our origins.

How is it possible for the disciplines of cosmology, geology, anthropology, biology, and history to fit together? These 48 lectures answer that question by weaving a single story from accounts of the past developed by a variety of scholarly disciplines. The result is a story stretching from the origins of the universe to the present day and beyond, in which human history is seen as part of the history of our Earth and biosphere, and the Earth's history, in turn, is seen as part of the history of the universe.

Whatever your views on climate change, it's important to understand how the current scientific consensus on global warming evolved out of basic physical principles and a broad range of observations. This lucid series of 12 lectures is designed to do exactly that-reviewing the most up-to-date research and explaining the concepts, tools, data, and analysis that have led an overwhelming number of climate scientists to conclude that Earth is indeed warming and that we humans are in great part responsible.

We use DNA routinely - to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future. But what, exactly is DNA, the self-replicating material present in nearly all living organisms?

Feeling stressed? You're not alone. Stress is an inherent aspect of life that can have tremendous negative effects on your mental and physical health. This makes coping with stress a critical part of how well we live.Once you understand the inner workings of your stress response system, you'll possess powerful knowledge that will help you understand and better deal with this common aspect of your busy life.

In this series of 24 fascinating lectures, an acclaimed teacher and psychologist gives you a bio-psychological perspective on both the way we humans navigate and react to the world around us and an understanding of the ways in which that process is ever-changing.

Everything we now know about the universe - from the behavior of quarks to the birth of galaxies - has come from people who've been willing to ponder the unanswerable. And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of grappling with some of the universe's most vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered and explored by today's scientists?

One of the greatest scientific feats of our era is the astonishing progress made in understanding biology-the intricate machinery of life-a progress to which the period we are living in right now has contributed the most.As you read these words, researchers are delving ever deeper into the workings of living systems, turning their discoveries into new medical treatments, improved methods of growing food, and innovative products that are already changing the world.

Quantum physics is an astounding (and mind-boggling) field of science, but can you actually use it to change your life? Absolutely yes, says Dr. Quantum. On A User's Guide to Your Universe, Dr. Quantum, who goes by day as mild-mannered physicist Dr. Fred Alan Wolf, teaches that anyone can understand quantum physics. What's more, it is the most useful, immediate, and relevant kind of science you can learn to profoundly affect your day-to-day life.

In the tradition of Carl Sagan, Rachel Carson, and Stephen Hawking, a new voice has emerged with the unique gift of translating cutting-edge science into clear, accessible language: Dr. Bruce Lipton.
