  • Where are all the aliens? | Stephen Webb

    Where are all the aliens? | Stephen Webb

    The universe is incredibly old, astoundingly vast and populated by trillions of planets — so where are all the aliens? Astronomer Stephen Webb has an explanation: we’re alone in the universe. In a mind-expanding talk, he spells out the remarkable barriers a planet would need to clear in order to host an extraterrestrial civilization — and makes a case for the beauty of our potential cosmic loneliness. “The silence of the universe is shouting, ‘We’re the creatures who got lucky,’” Webb says.

    This company pays kids to do their math homework | Mohamad Jebara

    Mohamad Jebara loves mathematics — but he’s concerned that too many students grow up thinking that this beautiful, rewarding subject is difficult and boring. His company is experimenting with a bold idea: paying students for completing weekly math homework. He explores the ethics of this model and how it’s helping students — and why learning math is crucial in the era of fake news.

  • Electrical experiments with plants that count and communicate | Greg Gage

    Electrical experiments with plants that count and communicate | Greg Gage

    Neuroscientist Greg Gage takes sophisticated equipment used to study the brain out of graduate-level labs and brings them to middle- and high-school classrooms (and, sometimes, to the TED stage.) Prepare to be amazed as he hooks up the Mimosa pudica, a plant whose leaves close when touched, and the Venus flytrap to an EKG to show us how plants use electrical signals to convey information, prompt movement and even count.

  • What happens when our computers get smarter than we are? | Nick Bostrom

    What happens when our computers get smarter than we are? | Nick Bostrom

    Artificial intelligence is getting smarter by leaps and bounds — within this century, research suggests, a computer AI could be as “smart” as a human being. And then, says Nick Bostrom, it will overtake us: “Machine intelligence is the last invention that humanity will ever need to make.” A philosopher and technologist, Bostrom asks us to think hard about the world we’re building right now, driven by thinking machines. Will our smart machines help to preserve humanity and our values — or will they have values of their own?

  • What will future jobs look like? | Andrew McAfee

    What will future jobs look like? | Andrew McAfee

    Economist Andrew McAfee suggests that, yes, probably, droids will take our jobs — or at least the kinds of jobs we know now. In this far-seeing talk, he thinks through what future jobs might look like, and how to educate coming generations to hold them.
