Throughout history, speculation has spurred beautiful, revolutionary science -- opening our eyes to entirely new universes. "I'm not talking about science that takes baby steps," says Eric Haseltine. "I'm talking about science that takes enormous leaps." In this talk, Haseltine passionately takes us to the edges of intellectual pursuit with two ideas -- one that's already made history, and the other that's digging into one of humanity's biggest questions with admirable ambition (and a healthy dose of skepticism from many). Watch »

How do you define "nature?" If we define it as that which is untouched by humans, then we won't have any left, says environmental writer Emma Marris. She urges us to learn a new definition of nature -- one that includes not only pristine wilderness but also the untended patches of plants growing in urban spaces -- and encourages us to bring our children out to touch and tinker with it, so that one day they might love and protect it.

Professional Arab women often juggle more responsibilities than their male counterparts, and they can face more cultural rigidity than Western women.

Tracing her career as an engineer, advocate and mother in Abu Dhabi, Leila Hoteit shares three lessons she's learned about thriving in the modern world. Watch »

Adam Savage makes things and tells stories -- and he uses costumes to add humor, color and clarity to the stories he tells. Tracing his lifelong love of costumes from a childhood space helmet made of an ice cream tub to a No-Face costume he wore to Comic-Con, he explores the fascinating world of cosplay and the meaning it creates for its community. "We're connecting with something important inside of us," he says. "The costumes are how we reveal ourselves to each other." Watch »

Quote of the Week

Let's give you a story. It's a rainy election day in a small country -- that can be my country, but could be also your country. And because of the rain until 4 o'clock in the afternoon, nobody went to the polling stations. But then the rain stopped, people went to vote. And when the votes had been counted, three-fourths of the people have voted with a blank ballot.

And the government and the opposition, they are simply paralyzed. Because you know what to do about protests. You know who to arrest, who to negotiate with. But what to do about people who are voting with a blank ballot? ... Basically they went to the ballot boxes to say that they have nobody to vote for.

This is the opening of a beautiful novel by José Saramago called Seeing. But in my view it very well captures part of the problem that we have with democracy in Europe these days. On one level nobody's questioning that democracy is the best form of government. Democracy is the only game in town. The problem is that many people start to believe that it is not a game worth playing."

Can democracy exist without trust?

What caused the war in Syria? Oppression, drought and religious differences all played key roles, but Marwa Al-Sabouni suggests another reason: architecture. Speaking to us over the Internet from Homs, where for the last six years she has watched the war tear her city apart, Al-Sabouni suggests that Syria's architecture divided its once tolerant and multicultural society into single-identity enclaves defined by class and religion. The country's future now depends on how it chooses to rebuild. Watch »

We are embarrassingly unaware of how divided our societies are, and Brexit grew out of a deep, unexamined divide between those that fear globalization and those that embrace it, says social scientist Alexander Betts. How do we now address that fear as well as growing disillusionment with the political establishment, while refusing to give in to xenophobia and nationalism? Join Betts as he discusses four post-Brexit steps toward a more inclusive world. Watch »

As she says: "When we design for disability first, you often stumble upon solutions that are better than those when we design for the norm." Watch »

I had no idea that you could suffer in this way and then have your whole experience, your story, denied, buried and forgotten. And it seemed that whenever there was a camera around, or a video or film camera, it was a great deal harder to do -- for those in power to bury the story."

Julia Galef: Why you think you're right -- even if you're wrong

11:37 minutes · Filmed Feb 2016 · Posted Jun 2016 · TEDxPSU

Perspective is everything, especially when it comes to examining your beliefs. Are you a soldier, prone to defending your viewpoint at all costs -- or a scout, spurred by curiosity? Julia Galef examines the motivations behind these two mindsets and how they shape the way we interpret information, interweaved with a compelling history lesson from 19th-century France. When your steadfast opinions are tested, Galef asks: "What do you most yearn for? Do you yearn to defend your own beliefs or do you yearn to see the world as clearly as you possibly can?"

We're on the edge of a new frontier in art and creativity -- and it's not human. Blaise Agüera y Arcas, principal scientist at Google, works with deep neural networks for machine perception and distributed learning. In this captivating demo, he shows how neural nets trained to recognize images can be run in reverse, to generate them. The results: spectacular, hallucinatory collages (and poems!) that defy categorization. "Perception and creativity are very intimately connected," Agüera y Arcas says. "Any creature, any being that is able to do perceptual acts is also able to create." Watch »

Wanda Diaz Merced studies the light emitted by gamma-ray bursts, the most energetic events in the universe. When she lost her sight and was left without a way to do her science, she had a revelatory insight: the light curves she could no longer see could be translated into sound.

"It has to be available to everyone, because we are all natural explorers." Watch »
