In 2013, a group of researchers wanted to create an AI system that could beat every Atari game. They developed a system called Deep Q Networks (DQN) and less than two years later, it was superhuman. But there was one notable exception. When playing Montezuma's Revenge, DQN couldn't score a single point. What was it that made this game so vexingl...

Human beings and computers alike share the challenge of how to get as much done as possible in a limited time. Over the last fifty or so years, computer scientists have learned a lot of good strategies for managing time effectively— and they have a lot of experience with what can go wrong. Brian Christian shares how we can use some of these insi...

Physicist Brian Greene explains superstring theory, the idea that minscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.

A pioneer in research on play, Dr. Stuart Brown says humor, games, roughhousing, flirtation and fantasy are more than just fun. Plenty of play in childhood makes for happy, smart adults -- and keeping it up can make us smarter at any age.

"Venus is too hot, Mars is too cold, and Earth is just right," says planetary scientist Dave Brain. But why?

Science fiction writer Monica Byrne imagines rich worlds populated with characters who defy our racial, social and gender stereotypes. In this performance, Byrne appears as a hologram named Pilar, transmitting a story of love and loss back to us from a near future when humans have colonized the universe. "It's always funny what you think the fut...

Bernie Krause has been recording wild soundscapes -- the wind in the trees, the chirping of birds, the subtle sounds of insect larvae -- for 45 years. In that time, he has seen many environments radically altered by humans, sometimes even by practices thought to be environmentally safe. A surprising look at what we can learn through nature's sym...

When Bran Ferren was just 9, his parents took him to see the Pantheon in Rome — and it changed everything. In that moment, he began to understand how the tools of science and engineering become more powerful when combined with art, with design and beauty. Ever since, he's been searching for a convincing modern-day equivalent to Rome's masterpiec...

On August 21, 2017, the moon's shadow raced from Oregon to South Carolina in what some consider to be the most awe-inspiring spectacle in all of nature: a total solar eclipse. Umbraphile David Baron chases these rare events across the globe, and in this ode to the bliss of seeing the solar corona, he explains why you owe it to yourself to witnes...

It's not a demo, more of a philosophical argument: Why did Sergey Brin and his team at Google want to build an eye-mounted camera/computer, codenamed Glass? Onstage at TED2013, Brin calls for a new way of seeing our relationship with our mobile computers -- not hunched over a screen but meeting the world heads-up.

Why does the Earth spin? Does a basketball falling from a spinning merry-go-round fall in a curve, as it appears to, or in a straight line? How can speed be manipulated while spinning? In short, why is the spinning motion so special? Brian Jones details the dizzyingly wide array of ways that spinning affects our lives. [Directed by Flaming Medus...

In tough economic times, our exploratory science programs -- from space probes to the LHC -- are first to suffer budget cuts. Brian Cox explains how curiosity-driven science pays for itself, powering innovation and a profound appreciation of our existence.

What makes you, you? Psychologists like to talk about our traits, or defined characteristics that make us who we are. But Brian Little is more interested in moments when we transcend those traits -- sometimes because our culture demands it of us, and sometimes because we demand it of ourselves. Join Little as he dissects the surprising differenc...

We are rapidly moving towards a world where computers have the ability to not only process tons of information, but to gather it by seeing and hearing. Steve Brown takes a peek into the future to explore how these advances will impact our lives.

Since humanity first imagined the reality of intelligent machines, we've been afraid that they'll overpower us one day.
