70,000 years ago humans were insignificant animals. The most important thing to know about prehistoric humans is that they were unimportant. Their impact on the world was very small, less than that of jellyfish, woodpeckers or bumblebees.
What motivates us to work? Contrary to conventional wisdom, it isn't just money. But it's not exactly joy either. It seems that most of us thrive by making constant progress and feeling a sense of purpose. Behavioral economist Dan Ariely presents two eye-opening experiments that reveal our unexpected and nuanced attitudes toward meaning in our work.
Some of us learn best in the classroom, and some of us ... well, we don't. But we still love to learn, to find out new things about the world and challenge our minds.

Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

He saved the future from Evil Robots! Isaac Asimov dreamed a better future where we need not fear our own technology. His I, Robot stories of a sci-fi future where robots can do our jobs for us lead to the creation of real-life industrial robots and paved the way for a robo-friendly world.
Why does an atheist bother to get up in the morning? That's the question Richard Dawkins seeks to answer as he continues his exploration of the big questions of life in a world shaking off religious faith. In a journey that takes him from the casinos of Las Vegas to Buddhist monasteries in the foothills of the Himalayas, Dawkins examines how both religious and non-religious people struggle to find meaning in their lives. He looks at how our existence is ruled by chance, meeting people whose fate was to be born into extreme poverty in India's slums and the survivors of a natural disaster in Joplin, Missouri, which was ripped apart in 2011 by a tornado on a random course.
