How we found the giant squid
8 minutes 38 seconds
Humankind has been looking for the giant squid (Architeuthis) since we first started taking pictures underwater. But the elusive deep-sea predator could never be caught on film. Oceanographer and inventor Edith Widder shares the key insight -- and the teamwork -- that helped to capture the squid on film for the first time.
Hunting for dinosaurs showed me our place in the universe
15 minutes 49 seconds
What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus -- a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet -- and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time.
Archaeology from space
5 minutes 20 seconds
In this short talk, TED Fellow Sarah Parcak introduces the field of "space archaeology" -- using satellite images to search for clues to the lost sites of past civilizations.
Meet the dazzling flying machines of the future
11 minutes 35 seconds
When you hear the word "drone," you probably think of something either very useful or very scary. But could they have aesthetic value? Autonomous systems expert Raffaello D'Andrea develops flying machines, and his latest projects are pushing the boundaries of autonomous flight -- from a flying wing that can hover and recover from disturbance to an eight-propeller craft that's ambivalent to orientation ... to a swarm of tiny coordinated micro-quadcopters. Prepare to be dazzled by a dreamy, swirling array of flying machines as they dance like fireflies above the TED stage.
The boiling river of the Amazon
15 minutes 49 seconds
When Andrés Ruzo was a young boy in Peru, his grandfather told him a story with an odd detail: There is a river, deep in the Amazon, which boils as if a fire burns below it. Twelve years later, after training as a geoscientist, he set out on a journey deep into the jungle of South America in search of this boiling river. At a time when everything seems mapped and measured, join Ruzo as he explores a river that forces us to question the line between known and unknown ... and reminds us that there are great wonders yet to be discovered.
Jill Bolte Taylor
My stroke of insight
18 minutes 19 seconds
Jill Bolte Taylor got a research opportunity few brain scientists would wish for: She had a massive stroke, and watched as her brain functions -- motion, speech, self-awareness -- shut down one by one. An astonishing story.
In the Internet age, dance evolves ...
16 minutes 48 seconds
The LXD (the Legion of Extraordinary Dancers) electrify the TED stage with an emerging global street-dance culture, revved up by the Internet. Directed by Jon M. Chu, this astonishing troupe of dancers and musicians show off their superpowers.
Here's how we take back the Internet
35 minutes 2 seconds
Appearing by telepresence robot, Edward Snowden speaks at TED2014 about surveillance and Internet freedom. The right to data privacy, he suggests, is not a partisan issue, but requires a fundamental rethink of the role of the internet in our lives — and the laws that protect it. "Your rights matter," he says, "because you never know when you're going to need them." Chris Anderson interviews, with special guest Tim Berners-Lee.
5 minutes 27 seconds
David Gallo shows jaw-dropping footage of amazing sea creatures, including a color-shifting cuttlefish, a perfectly camouflaged octopus, and a Times Square's worth of neon light displays from fish who live in the blackest depths of the ocean. This short talk celebrates the pioneering work of ocean explorers like Edith Widder and Roger Hanlon.
Photos from a storm chaser
3 minutes 26 seconds
Photographer Camille Seaman has been chasing storms for 5 years. In this talk she shows stunning, surreal photos of the heavens in tumult.
