Curious George

Just in the last three years a flood of new scientific findings, driven by revelations discovered in the human genome, has provided compelling new answers to many long-standing mysteries about our most ancient ancestors, the people who first evolved in Africa and then went on to colonize the whole world. Nicholas Wade weaves this host of news-making findings together for the first time into an intriguing new history of the human story before the dawn of civilization.

Twenty-five years ago, Neil Howe and the late William Strauss dazzled the world with a provocative new theory of American history. Looking back at the last 500 years, they’d uncovered a distinct pattern: modern history moves in cycles, each one lasting roughly 80 to 100 years, the length of a long human life, with each cycle composed of four eras—or “turnings”—that always arrive in the same order and each last about 25 years. The last of these eras—the fourth turning—was always the most perilous, a period of civic upheaval and national mobilization.

Psychologists study which cognitive operations underpin a given conscious perception. Neuroscientists track the neural correlates of consciousness in the brain, the organ of the mind. But why the brain and not, say, the liver? How can the brain, three pounds of highly excitable matter, a piece of furniture in the universe, subject to the same laws of physics as any other piece, give rise to subjective experience? Koch argues that what is needed to answer these questions is a quantitative theory that starts with experience and proceeds to the brain.

For generations, everything has been getting faster, better, and cheaper. Finally, we reached the point that almost anything you could ever want could be sent to your home within days - even hours - of when you decided you wanted it. America made that happen, but now America has lost interest in keeping it going.

This lecture series takes you on a far-reaching journey around the globe - from China to the Americas to New Zealand - to shed light on how two dozen of the top discoveries, inventions, political upheavals, and ideas since 1400 have shaped the modern world. In just 24 thought-provoking lectures, you'll get the amazing story of how life as we know it developed. Starting in the early 15th century and culminating in the age of social media, you'll encounter astounding threads that weave through the centuries, joining these turning points in ways that may come as a revelation.

Life is getting better at an accelerating rate. Food availability, income, and life span are up; disease, child mortality, and violence are down all across the globe. Though the world is far from perfect, necessities and luxuries alike are getting cheaper; population growth is slowing; Africa is following Asia out of poverty; the Internet, the mobile phone, and container shipping are enriching people's lives as never before.

In 24 thought-provoking lectures designed for nonscientists, this course explores today's exciting field of genomics, the study of the vast storehouse of information contained within chromosomes. Your professor is Princeton University biologist Lee M. Silver, an acclaimed teacher, scientist, and author of popular books on biotechnology, genetics, and their impact on society.

In this witty, often terrifying work of cultural criticism, Postman chronicles our transformation into a Technopoly: a society that no longer merely uses technology as a support system but instead is shaped by it. According to Postman, technology is rapidly gaining sovereignty over social institutions and national life to become self-justifying, self-perpetuating, and omnipresent. He warns that this will have radical consequences for the meanings of politics, art, religion, family, education, and more.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

With wonder, wit, and flair - and in record time and space - geophysicist David Bercovici explains how everything came to be everywhere, from the creation of stars and galaxies to the formation of Earth's atmosphere and oceans to the origin of life and human civilization. Bercovici marries humor and legitimate scientific intrigue, rocketing listeners across nearly 14 billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis.
