What is TED? This primer of 11 classic TED Talks show you the wide range of topics covered — and introduce you to beloved speakers like. Here they are:

Ken Robinson: “Do schools kill creativity?” (19:24)

Sir Ken Robinson makes an entertaining and profoundly moving case for creating an education system that nurtures (rather than undermines) creativity.

David Gallo: “Underwater astonishments” (6:27)

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.

Sarah Kay: “If I should have a daughter….” (18:25)

“If I should have a daughter, instead of Mom, she’s gonna call me Point B … ” began spoken word poet Sarah Kay, in a talk that inspired two standing ovations at TED2011. She tells the story of her metamorphosis — from a wide-eyed teenager soaking in verse at New York’s Bowery Poetry Club to a teacher connecting kids with the power of self-expression through Project V.O.I.C.E. — and gives two breathtaking performances of “B” and “Hiroshima.”

Hans Rosling: “The best stats you’ve ever seen” (19:50)

You’ve never seen data presented like this. With the drama and urgency of a sportscaster, statistics guru Hans Rosling debunks myths about the so-called “developing world.”

Chimamanda Ngozi Adichie: “The danger of a single story” (18:49)

Our lives, our cultures, are composed of many overlapping stories. Novelist Chimamanda Adichie tells the story of how she found her authentic cultural voice — and warns that if we hear only a single story about another person or country, we risk a critical misunderstanding.

Hugh Herr: “The new bionics that let us run, climb, and dance” (19:00)

Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature’s own designs. Herr lost both legs in a climbing accident 30 years ago; now, as the head of the MIT Media Lab’s Biomechatronics group, he shows his incredible technology in a talk that’s both technical and deeply personal — with the help of ballroom dancer Adrianne Haslet-Davis, who lost her left leg in the 2013 Boston Marathon bombing, and performs again for the first time on the TED stage.

Brené Brown: “The power of vulnerability” (20:19)

Brené Brown studies human connection — our ability to empathize, belong, love. In a poignant, funny talk, she shares a deep insight from her research, one that sent her on a personal quest to know herself as well as to understand humanity. A talk to share.

Bryan Stevenson: “We need to talk about an injustice” (23:41)

In an engaging and personal talk — with cameo appearances from his grandmother and Rosa Parks — human rights lawyer Bryan Stevenson shares some hard truths about America’s justice system, starting with a massive imbalance along racial lines: a third of the country’s black male population has been incarcerated at some point in their lives. These issues, which are wrapped up in America’s unexamined history, are rarely talked about with this level of candor, insight and persuasiveness.

Alejandro Aravena: “My architectural philosophy? Bring the community into the process” (15:49)

When asked to build housing for 100 families in Chile ten years ago, Alejandro Aravena looked to an unusual inspiration: the wisdom of favelas and slums. Rather than building a large building with small units, he built flexible half-homes that each family could expand on. It was a complex problem, but with a simple solution — one that he arrived at by working with the families themselves. With a chalkboard and beautiful images of his designs, Aravena walks us through three projects where clever rethinking led to beautiful design with great benefit.

Amy Cuddy: “Your body language shapes who you are” (21:02)

Body language affects how others see us, but it may also change how we see ourselves. Social psychologist Amy Cuddy shows how “power posing” — standing in a posture of confidence, even when we don’t feel confident — can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success.

David Christian: “The history of our world in 18 minutes” (17:40)

Backed by stunning illustrations, David Christian narrates a complete history of the universe, from the Big Bang to the Internet, in a riveting 18 minutes. This is “Big History”: an enlightening, wide-angle look at complexity, life and humanity, set against our slim share of the cosmic timeline.
