What Makes a Terrorist

   2016    Culture
Hosted by Morgan Freeman, this series explores the deepest mysteries of existence. These questions have been pondered by the most exquisite minds of the human race. Now, science has evolved to the point where hard facts and evidence may be able to provide us with answers instead of philosophical theories. In the first episode of the season 7, terrorists, like any group, have a cause to rally around. But for them, the cause justifies the deliberate targeting of innocent civilians. How can they think that way? Now, science is peering into the dark heart of terror networks to find out why.

What Makes Me

   2015    Medicine
'What Makes Me?', explores the question of how the brain gives rise to our thoughts, emotions, our memories and personality. Philosophers and great thinkers have for millennia pondered the question of how physical stuff can give rise to mental processes. Last century, the new field of neuroscience joined the discussion, and Dr David Eagleman explains that to a neuroscientist, the answers to such questions lie in a deep understanding of the brain.

When Did Time Begin

   2014    Science
We float along the river of time. But does that river have a source? Where did time come from? Some believe time and space are one thing, and the Big Bang started the cosmic clock. Others believe the universe existed for almost half a million "years" before light could move and time began. Still others say time is older than our universe. But what if time itself is an illusion? Incredible new experiments may hold the answer. One groundbreaking experiment gives us the power to punch holes in time…and another may create a machine that operates outside time’s boundaries!

When Knowledge Conquered Fear

   2014    Science
The episode begins with Tyson describing how pattern recognition manifested in early civilization as using astronomy and astrology to predict the passing of the seasons, including how the passage of a comet was often taken as an omen. Tyson continues to explain that the origin of comets only became known in the 20th century due to the work of Jan Oort and his hypothesis of the Oort cloud. Tyson then continues to relate the collaboration between Edmond Halley and Isaac Newton in the last part of the 17th century in Cambridge. The collaboration would result in the publication of Philosophiæ Naturalis Principia Mathematica, the first major work to describe the laws of physics in mathematical terms, despite objections and claims of plagiarism from Robert Hooke and financial difficulties of the Royal Society of London. Tyson explains how this work challenged the prevailing notion that God had planned out the heavens, but would end up influencing many factors of modern life, including space flight. Tyson further describes Halley's contributions including determining Earth's distance to the sun, the motion of stars and predicting the orbit of then-unnamed Halley's Comet using Newton's laws. Tyson contrasts these scientific approaches to understanding the galaxy compared to what earlier civilizations had done, and considers this advancement as mankind's first steps into exploring the universe. The episode ends with an animation of the Milky Way and Andromeda galaxies' merging based on the principles of Newton's laws.

When Will Time End

   2012    Science
Discover the Eras of the Universe and the answer to this big question: When Will Time End? Once the notion that the universe started with a rapid inflation nicknamed the Big Bang became accepted by the majority of scientists, many possible fates are predicted by rival scientific hypotheses, including futures of both finite and infinite duration. The ultimate fate of the universe is dependent on the shape of the universe and what role Dark energy will play as the universe ages.
