Special guest Stephen Colbert of Comedy Central's Colbert Report talks about the joys of being a science geek. Brilliant scientific discoveries and cutting edge technology have transformed our world, yet many people are turned off by science. Where has the excitement for science gone, and how can we get it back? Stephen Colbert developed an interest in science at a young age, and now he shares that fascination by inviting scientists to appear on his show The Colbert Report.

Scientists have been searching for aliens in our solar system and beyond, but have not yet found evidence that life exists beyond Earth. SETI, the Search for Extraterrestrial Intelligence, has been scanning the stars for alien radio beacons for 50 years. Radio and TV broadcasts have been leaking from Earth's atmosphere for over a century, and these traveling time capsules could eventually reach a broader audience than ever imagined.

The Star Trek TV and movie series imagine a bright future for humans in space, one in which we explore alien worlds with the aid of advanced technology. Because the writers tried to include as much realistic science as possible within the fictional framework, the stories have been an inspiration for students, scientists, inventors, and anyone interested in pondering our destiny on Earth and beyond.

This year marks the 400th anniversary of Galileo’s use of the first telescope. On this week’s show, we reflect on how telescopes have changed our perception of our place in the universe, how small we are in size, space, and time. Our guests include Dava Sobel, author of The Planets, Vatican Astronomer Father Chris Corbally, and astronaut Paul Richards.

Mark Twain said, “Get your facts first, then you can distort them as you please.” Pseudoscience adheres to this adage, but are their distortions deliberate, the result of scientific ignorance, or due to a deep desire for extraordinary possibilities? In our quest to understand the universe, how can we be sure our conclusions are correct? Human beings have evolved to find meaningful patterns in nature, but sometimes the patterns we see are just figments of our imagination — or perhaps the result of wishful thinking.

My Big TOE: Awakening, written by a nuclear physicist in the language of contemporary culture, unifies science and philosophy, physics and metaphysics, mind and matter, purpose and meaning, the normal and the paranormal. The entirety of human experience (mind, body, and spirit) including both our objective and subjective worlds is brought together under one seamless scientific understanding.

We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: mental disorders are metabolic disorders of the brain. Brain Energy will transform the field of mental health, and the lives of countless people around the world.

Remarkable new discoveries affirm the octopus as one of nature’s most intelligent and complex animals. This new book brings us closer than ever to these elusive creatures. The companion to the highly anticipated National Geographic television special, this book explores the alluring underwater world of the octopus—a creature that resembles an alien lifeform, but whose behavior has earned it a reputation as one of the most intelligent animals on the planet.

Hilarious, fascinating, and a roller coaster of dizzying, historical what-ifs, Napoleon's Hemorrhoids is a potpourri for serious historians and casual history buffs. In one of Phil Mason's many revelations, you'll learn that Communist jets were two minutes away from opening fire on American planes during the Cuban missile crisis, when they had to turn back as they were running out of fuel. You'll discover that before the Battle of Waterloo, Napoleon's painful hemorrhoids prevented him from mounting his horse to survey the battlefield.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.
