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."

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. Through sonification, she regained mastery over her work, and now she's advocating for a more inclusive scientific community. "Science is for everyone," she says. "It has to be available to everyone, because we are all natural explorers."

How do you build a product people really want? Allow consumers to be a part of the process. "Empathy for what your customers want is probably the biggest leading indicator of business success," says designer Tom Hulme. In this short talk, Hulme lays out three insightful examples of the intersection of design and user experience, where people have developed their own desire paths out of necessity. Once you know how to spot them, you'll start noticing them everywhere.

What makes you, you? Psychologists like to talk about our traits, or defined characteristics that make us who we are. But Brian Little is more interested in moments when we transcend those traits -- sometimes because our culture demands it of us, and sometimes because we demand it of ourselves. Join Little as he dissects the surprising differences between introverts and extroverts and explains why your personality may be more malleable than you think.

Seema Bansal forged a path to public education reform for 15,000 schools in Haryana, India, by setting an ambitious goal: by 2020, 80 percent of children should have grade-level knowledge. She's looking to meet this goal by seeking reforms that will work in every school without additional resources. Bansal and her team have found success using creative, straightforward techniques such as communicating with teachers using SMS group chats, and they have already measurably improved learning and engagement in Haryana's schools.

Ninety-six percent of genome studies are based on people of European descent. The rest of the world is virtually unrepresented -- and this is dangerous, says geneticist and TED Fellow Keolu Fox, because we react to drugs differently based on our genetic makeup. Fox is working to democratize genome sequencing, specifically by advocating for indigenous populations to get involved in research, with the goal of eliminating health disparities. "The research community needs to immerse itself in indigenous culture," he says, "or die trying."

Gill Hicks's story is one of compassion and humanity, emerging from the ashes of chaos and hate. A survivor of the London terrorist bombings on July 7, 2005, she shares her story of the events of that day -- and the profound lessons that came as she learned how to live on.

How often does technology interrupt us from what we really mean to be doing? At work and at play, we spend a startling amount of time distracted by pings and pop-ups -- instead of helping us spend our time well, it often feels like our tech is stealing it away from us. Design thinker Tristan Harris offers thoughtful new ideas for technology that creates more meaningful interaction. He asks: "What does the future of technology look like when you're designing for the deepest human values?"

Chris Milk uses innovative technologies to make personal, interactive, human stories. Accompanied by Joshua Roman on cello and McKenzie Stubbert on piano, Milk traces his relationship to music and art -- from the first moment he remembers putting on headphones to his current work creating breakthrough virtual reality projects. VR is the last medium for storytelling, he says, because it closes the gap between audience and storyteller. To illustrate, he brought the TED audience together in the world's largest collective VR experience. Join them and take part in this interactive talk by getting a Google Cardboard and downloading the experience at with.in/TED.

TED Fellow Andrew Pelling is a biohacker, and nature is his hardware. His favorite materials are the simplest ones (and oftentimes he finds them in the garbage). Building on the cellulose structure that gives an apple its shape, he "grows" lifelike human ears, pioneering a process that might someday be used to repair body parts safely and cheaply. And he has some even wilder ideas to share ... "What I'm really curious about is if one day it will be possible to repair, rebuild and augment our own bodies with stuff we make in the kitchen," he says.

We're not going to end violence by telling people that it's morally wrong, says Jamila Raqib, executive director of the Albert Einstein Institution. Instead, we must find alternative ways to conduct conflict that are equally powerful and effective. Raqib promotes nonviolent resistance to people living under tyranny -- and there's a lot more to it than street protests. She shares encouraging examples of creative strategies that have led to change around the world and a message of hope for a future without armed conflict. "The greatest hope for humanity lies not in condemning violence but in making violence obsolete," Raqib says.

Half of the world's poorest people have something in common: they're small farmers. In this eye-opening talk, activist Andrew Youn shows how his group, One Acre Fund, is helping these farmers lift themselves out of poverty by delivering to them life-sustaining farm services that are already in use all over the world. Enter this talk believing we'll never be able to solve hunger and extreme poverty, and leave it with a new understanding of the scale of the world's biggest problems.

TED Fellow Negin Farsad weaves comedy and social commentary to cleverly undercut stereotypes of her culture. In this uproarious talk/stand-up hybrid, Farsad speaks on her documentary, The Muslims Are Coming!, narrates her fight with the MTA in New York and offers a detailed breakdown of the different types of haters she's encountered in her work. "Comedy is one of our best weapons," she says. "We've tried a lot of approaches to social justice, like war and competitive ice dancing -- but a lot of things are still kind of awful. I think it's time we try and tell a really good poop joke."

In some parts of the world, it's easier to get an automatic rifle than a glass of clean drinking water. Is this just the way it is? Samantha Nutt, doctor and founder of the international humanitarian organization War Child, explores the global arms trade -- and suggests a bold, common sense solution for ending the cycle of violence. "War is ours," she says. "We buy it, sell it, spread it and wage it. We are therefore not powerless to solve it."
