Why doesn’t magenta appear in the rainbow? The answer lies not in physics but in biology.
Your smartphone may feel like a friend — but a true friend would give you a smile once in a while. At TED2013, Keller Rinaudo demos Romo, the smartphone-powered mini robot who can motor along with you on a walk, slide you a cup of coffee across the table, and react to you with programmable expressions.
Cosmic Journeys examines the great promise of the Voyager mission and where it will lead us in our grand ambition to move out beyond our home planet. The two Voyager spacecraft are part of an ancient quest to push beyond our boundaries… to see what lies beyond the horizon. Now tens of billions of kilometers from Earth, two spacecraft are streaking out into the void. What will we learn about the Galaxy, the Universe, and ourselves from Voyager’s epic Journey to the stars?
How did the universe begin — and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.
Professor Moriarty requested that we re-visit one aspect of physics in the game Portal 2 – humour him!
At age 12, Freeman Hrabowski marched with Martin Luther King. Now he’s president of the University of Maryland, Baltimore County (UMBC), where he works to create an environment that helps under-represented students — specifically African-American, Latino and low-income learners — get degrees in math and science. He shares the four pillars of UMBC’s approach.
Adam Garone has an impressive moustache, and it’s for a good cause. A co-founder of Movember, Garone’s initiative to raise awareness for men’s health — by having men grow out their moustaches every November — began as a dare in a bar in 2003. Now, it’s a worldwide movement that raised $126 million for prostate cancer research last year.
There’s a pleasure in making things for yourself — especially something unexpected. William Gurstelle shows how to make your own speakers from objects probably already laying around your house, like copper wire and an empty yogurt cup.

But Jeff Hancock doesn’t believe that the anonymity of the internet encourages dishonesty. In fact, he says the searchability and permanence of information online may even keep us honest.
When are humans most happy? To gather data on this question, Matt Killingsworth built an app, Track Your Happiness, that let people report their feelings in real time. Among the surprising results: We’re often happiest when we’re lost in the moment. And the flip side: The more our mind wanders, the less happy we can be. (Filmed at TEDxCambridge.)
When two people are trying to make a deal — whether they’re competing or cooperating — what’s really going on inside their brains? Behavioral economist Colin Camerer shows research that reveals just how little we’re able to predict what others are thinking. And he presents an unexpected study that shows chimpanzees might just be better [...]
