Can a person disappear in plain sight? That’s the question Liu Bolin‘s remarkable work seems to ask. The Beijing-based artist is sometimes called “The Invisible Man” because in nearly all his art, Bolin is front and center — and completely unseen. He aims to draw attention to social and political issues by dissolving into the background.

In our digital world, social relations have become mediated by data. Without even realizing it, we’re barricading ourselves against strangeness -- people and ideas that don't fit the patterns of who we already know, what we already like and where we’ve already been. A call for technology to deliver us to what and who we need, even if it’s unfamiliar. (Filmed at TED@Intel.)

Clinical psychologist Meg Jay has a bold message for twentysomethings: Contrary to popular belief, your 20s are not a throwaway decade. In this provocative talk, Jay says that just because marriage, work and kids are happening later in life, doesn’t mean you can’t start planning now. She gives 3 pieces of advice for how twentysomethings can re-claim adulthood in the defining decade of their lives.

Sir Ken Robinson outlines 3 principles crucial for the human mind to flourish -- and how current education culture works against them. In a funny, stirring talk he tells us how to get out of the educational "death valley" we now face, and how to nurture our youngest generations with a climate of possibility.

Leaving a high-flying job in consulting, Angela Lee Duckworth took a job teaching math to seventh graders in a New York public school. She quickly realized that IQ wasn’t the only thing separating the successful students from those who struggled. Here, she explains her theory of “grit” as a predictor of success.

In a heart-melting moment, TED Talks Education host John Legend sits at the piano to sing "True Colors," giving the lyrics a special meaning for kids and teachers. "So don't be afraid / to let them show / your true colors / are beautiful, like a rainbow."

Why, why, why does our education system look so similar to the way it did 50 years ago? Millions of students were failing then, as they are now -- and it’s because we’re clinging to a business model that clearly doesn’t work. Education advocate Geoffrey Canada dares the system to look at the data, think about the customers and make systematic shifts in order to help greater numbers of kids excel.

Young poet, educator and activist Malcom London performs his stirring poem about life on the front lines of high school. He tells of the “oceans of adolescence” who come to school “but never learn to swim,” of “masculinity mimicked by men who grew up with no fathers.” Beautiful, lyrical, chilling.

Pearl Arredondo grew up in East Los Angeles, the daughter of a high-ranking gang member who was in and out of jail. Many teachers wrote her off as having a problem with authority. Now a teacher herself, she’s creating a different kind of school and telling students her story so that they know it's okay if sometimes homework isn’t the first thing on their minds.

It took a life-threatening condition to jolt chemistry teacher Ramsey Musallam out of ten years of “pseudo-teaching” to understand the true role of the educator: to cultivate curiosity. In a fun and personal talk, Musallam gives 3 rules to spark imagination and learning, and get students excited about how the world works.

Until recently, many teachers only got one word of feedback a year: “satisfactory.” And with no feedback, no coaching, there’s just no way to improve. Bill Gates suggests that even great teachers can get better with smart feedback -- and lays out a program from his foundation to bring it to every classroom.

For foreigners, learning to speak Chinese is a hard task. But learning to read the beautiful, often complex characters of the Chinese written language may be less difficult. ShaoLan walks through a simple lesson in recognizing the ideas behind the characters and their meaning -- building from a few simple forms to more complex concepts. Call it Chineasy.

In this well-argued talk, Timothy Bartik makes the macro-economic case for preschool education -- and explains why you should be happy to invest in it, even if you don't have kids that age (or kids at all). The economic benefits of well-educated kids, it turns out, go well beyond the altruistic. (Filmed at TEDxMiamiUniversity.)

Rita Pierson, a teacher for 40 years, once heard a colleague say, "They don't pay me to like the kids." Her response: "Kids don't learn from people they don’t like.’” A rousing call to educators to believe in their students and actually connect with them on a real, human, personal level.

What if Andy Warhol had it wrong, and instead of being famous for 15 minutes, we’re only anonymous for that long? In this short talk, Juan Enriquez looks at the surprisingly permanent effects of digital sharing on our personal privacy. He shares insight from the ancient Greeks to help us deal with our new “digital tattoos.”
