  • David Epstein: Are athletes really getting faster, better, stronger?

    Apr 29, 2014 | 15 min
    When you look at sporting achievements over the last decades, it seems like humans have gotten faster, better and stronger in nearly every way. Yet as David Epstein points out in this delightfully counter-intuitive talk, we might want to lay off the self-congratulation. Many factors are at play in shattering athletic records, and the development of our natural talents is just one of them.
  • James Patten: The best computer interface? Maybe ... your hands

    Apr 24, 2014 | 7 min
    "The computer is an incredibly powerful means of creative expression," says designer and TED Fellow James Patten. But right now, we interact with computers, mainly, by typing and tapping. In this nifty talk and demo, Patten imagines a more visceral, physical way to bring your thoughts and ideas to life in the digital world, taking the computer interface off the screen and putting it into your hands.
  • Jeremy Kasdin: The flower-shaped starshade that might help us detect Earth-like planets

    Apr 17, 2014 | 7 min
    Astronomers believe that every star in the galaxy has a planet, one fifth of which might harbor life. Only we haven't seen any of them -- yet. Jeremy Kasdin and his team are looking to change that with the design and engineering of an extraordinary piece of equipment: a flower petal-shaped "starshade" that allows a telescope to photograph planets from 50,000 kilometers away. It is, he says, the "coolest possible science."
  • Del Harvey: The strangeness of scale at Twitter

    Mar 27, 2014 | 10 min
    When hundreds of thousands of Tweets are fired every second, a one-in-a-million chance -- including unlikely sounding sounding scenarios that could harm users -- happens about 500 times a day. For Del Harvey, who heads Twitter’s Trust and Safety Team, these odds aren’t good. The security maven spends her days thinking about how to prevent worst-case scenarios while giving voice to people around the globe. With deadpan humor, she offers a window into how she keeps 240 million users safe.

    Feb 4, 2014 | 10 min
    We're all familiar with satellite imagery, but what we might not know is that much of it is out of date. That's because satellites are big and expensive, so there aren't that many of them up in space. As he explains in this fascinating talk, Dan Berkenstock and his team came up with a different solution, designing a cheap, lightweight satellite with a radically new approach to photographing what's going on on Earth.
  • Guy Hoffman: Robots with "soul"

  • Abha Dawesar: Life in the "digital now"

    Oct 30, 2013 | 13 min
    One year ago, Abha Dawesar was living in blacked-out Manhattan post-Sandy, scrounging for power to connect. As a novelist, she was struck by this metaphor: Have our lives now become fixated on the drive to digitally connect, while we miss out on what's real?
  • Amy Webb: How I hacked online dating

    Oct 2, 2013 | 18 min

    Sep 16, 2013 | 18 min
    How do you pick up a malicious online virus, the kind of malware that snoops on your data and taps your bank account? Often, it's through simple things you do each day without thinking twice. James Lyne reminds us that it's not only the NSA that's watching us, but ever-more-sophisticated cybercriminals, who exploit both weak code and trusting human nature.
  • Ron McCallum: How technology allowed me to read

    Sep 11, 2013 | 16 min

This emerging technology will allow us to print objects that then reshape themselves or self-assemble over time. Think: a printed cube that folds before your eyes, or a printed pipe able to sense the need to expand or contract.
  • Jennifer Healey: If cars could talk, accidents might be avoidable

    May 21, 2013 | 10 min
    When we drive, we get into a glass bubble, lock the doors and press the accelerator, relying on our eyes to guide us -- even though we can only see the few cars ahead of and behind us. But what if cars could share data with each other about their position and velocity, and use predictive models to calculate the safest routes for everyone on the road? Jennifer Healey imagines a world without accidents. (Filmed at TED@Intel.)
  • Sergey Brin: Why Google Glass?

    May 17, 2013 | 8 min
