Author of the New York Times best seller The Beginning of Infinity, David Deutsch, explores the four most fundamental strands of human knowledge: quantum physics, and the theories of knowledge, computation, and evolution - and their unexpected connections. Taken together, these four strands reveal a deeply integrated, rational, and optimistic worldview. It describes a unified fabric of reality that is objective and comprehensible, in which human action and thought are central.

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.

We may believe that we are the masters of our fates, but in reality, we are at the mercy of hundreds of trillions of single-celled organisms that exert control over every aspect of how our minds and bodies function. These are the diverse species of microbes that work together synergistically to communicate with each other and with every system in our bodies. You are your microbiome’s home, and it wants to take care of you, but first you have to protect it. In Gut Check, Dr. Steven Gundry reveals the emerging science proving that Hippocrates was right—all disease begins in the gut.

The science of emotion is in the midst of a revolution on par with the discovery of relativity in physics and natural selection in biology. Leading the charge is psychologist and neuroscientist Lisa Feldman Barrett, whose research overturns the long-standing belief that emotions are automatic, universal, and hardwired in different brain regions. Instead, Barrett shows, we construct each instance of emotion through a unique interplay of brain, body, and culture.

Ingo Swann -- renowned psi researcher -- reveals a long-held secret series of experiences with a "deep black" agency whose apparent charter was simple: UFOs and extraterrestrials on the moon and worries about ET telepathic/mind control powers. The agency was so secret that it had no paper trail, and hence no written secrecy agreements. Only the verbal ones, which in Ingo's case expired several years ago.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

They have an inner peace that seems to offset their power and strength. That may explain why no other animal on the planet is as revered as the bear.
