TED is a nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. Since then its scope has become ever broader. Along with two annual conferences -- the TED Conference in Long Beach and Palm Springs each spring, and the TEDGlobal conference in Edinburgh UK each summer -- TED includes the award-winning TEDTalks video site, the Open Translation Project and TED Conversations, the inspiring TED Fellows and TEDx programs, and the annual TED Prize.

TEDTalks began as a simple attempt to share what happens at TED with the world. Under the moniker "ideas worth spreading," talks were released online. They rapidly attracted a global audience in the millions. Indeed, the reaction was so enthusiastic that the entire TED website has been reengineered around TEDTalks, with the goal of giving everyone on-demand access to the world's most inspiring voices.

In an impassioned talk, Morris uncovers the causes of "pushout" and shows how we can work to turn all schools into spaces where black girls can heal and thrive.

If we really want to address climate change, we need to make gender equity a reality, says writer and environmentalist Katharine Wilkinson. As part of Project Drawdown, Wilkinson has helped scour humanity's wisdom for solutions to draw down heat-trapping, climate-changing emissions: obvious things like renewable energy and sustainable diets and not so obvious ones, like the education and empowerment of women. In this informative, bold talk, she shares three key ways that equity for women and girls can help stop global warming. "Drawing down emissions depends on rising up," Wilkinson says.

The way we're taught to live has got to change, says author Casey Gerald. Too often, we hide parts of ourselves in order to fit in, win praise, be accepted. But at what cost? In this inspiring talk, Gerald shares the personal sacrifices he made to attain success in the upper echelons of American society — and shows why it's time for us to have the courage to live in the raw, strange magic of ourselves.

You probably know the common symptoms of a heart attack: chest and arm pain, shortness of breath and fatigue. But there's another kind that's just as deadly and harder to detect because the symptoms are silent. In this quick talk, 17-year-old inventor Akash Manoj shares the device he's developed to stop this silent killer: a noninvasive, inexpensive, wearable patch that alerts patients during a critical moment that could mean the difference between life and death.

From London to Tokyo, climate change is causing cities to sink — and our modern concrete infrastructure is making us even more vulnerable to severe flooding, says landscape architect and TED Fellow Kotchakorn Voraakhom. But what if we could design cities to help fight floods? In this inspiring talk, Voraakhom shows how she developed a massive park in Bangkok that can hold a million gallons of rainwater, calling for more climate change solutions that connect cities back to nature.

The American election system is complicated, to say the least — but voting is one of the most tangible ways that each of us can shape our communities. How can we make the system more modern, inclusive and secure? Civic engagement champion Tiana Epps-Johnson shares what's needed to bring voting in the US into the 21st century — and to get every person to the polls.

2019x23 Soraya Chemaly: The power of women's anger

  • 2019-01-27T23:00:00-06:00 — 15 mins

Anger is a powerful emotion — it warns us of threat, insult, indignity and harm. But across the world, girls and women are taught that their anger is better left unvoiced, says author Soraya Chemaly. Why is that, and what might we lose in this silence? In a provocative, thoughtful talk, Chemaly explores the dangerous lie that anger isn't feminine, showing how women's rage is justified, healthy and a potential catalyst for change.

The Montreal Protocol proved that the world could come together and take action on climate change. Thirty years after the world's most successful environmental treaty was signed, atmospheric scientist Sean Davis examines the world we avoided when we banned chlorofluorocarbons — and shares lessons we can carry forward to address the climate crisis in our time.

What does it take to build a national movement? In a captivating conversation with TEDWomen curator Pat Mitchell, Marian Wright Edelman reflects on her path to founding the Children's Defense Fund in 1973 — from the early influence of growing up in the segregated American South to her activism with Dr. Martin Luther King Jr. — and shares how growing older has only made her more radical.

"The climate crisis has already been solved. We already have all the facts and solutions," Thunberg says. "All we have to do is to wake up and change."

Did you know that almost 150 million people worldwide are born intersex — with biology that doesn't fit the standard definition of male or female? (That's as many as the population of Russia.) At age 10, Emily Quinn found out she was intersex, and in this wise, funny talk, she shares eye-opening lessons from a life spent navigating society's thoughtless expectations, doctors who demanded she get unnecessary surgery — and advocating for herself and the incredible variety that humans come in.

(Contains mature content)

"Where does it hurt?" It's a question that activist and educator Ruby Sales has traveled the US asking, looking deeply at the country's legacy of racism and searching for sources of healing. In this moving talk, she shares what she's learned, reflecting on her time as a freedom fighter in the civil rights movement and offering new thinking on pathways to racial justice.

The path to skill around the globe has been the same for thousands of years: train under an expert and take on small, easy tasks before progressing to riskier, harder ones. But right now, we're handling AI in a way that blocks that path — and sacrificing learning in our quest for productivity, says organizational ethnographer Matt Beane. What can be done? Beane shares a vision that flips the current story into one of distributed, machine-enhanced mentorship that takes full advantage of AI's amazing capabilities while enhancing our skills at the same time.

Is women's sexuality more complicated than men's? Well, not really, no, says author Sarah Barmak.

Matt Mullenweg, cofounder of Wordpress and CEO of Automattic (which has a 100 percent distributed workforce), shares his secrets.

Finding a job used to start with submitting your résumé to a million listings and never hearing back from most of them. But more and more companies are using tech-forward methods to identify candidates. If AI is the future of hiring, what does that mean for you? Technologist Priyanka Jain gives a look at this new hiring landscape.

Past generations found a company to work for and then stayed there for decades. But today, we rarely stay in the same job (let alone on the same career path) and we don't rely on a single income stream. The tools and resources are out there for us to do our own thing, and more of us are going with the entrepreneurial spirit — even if it's on the side of a traditional job. Podcaster and marketer Nicaila Matthews Okome helps survey the scene.

Most companies operate on a set of policies: mandated vacation days, travel guidelines, standard work hours, annual goals. But what happens when a company looks less to control and more to trust?

"Sí, se puede!" — "Yes, we can!" It's the rallying cry Dolores Huerta came up with as a young activist in the 1970s, and she's lived by it in her tireless pursuit of civil rights ever since. With her signature wit and humor, Huerta reflects on her life's work, offering inspiration for anybody trying to overcome apathy, get involved and find their own power.

What is a border? It's a line on a map, a place where cultures mix and merge in beautiful, sometimes violent and occasionally ridiculous ways. And a border wall? An overly simplistic response to that complexity, says architect Ronald Rael. In a moving, visual talk, Rael reimagines the physical barrier that divides the United States and Mexico — sharing satirical, serious works of art inspired by the borderlands and showing us the border we don't see in the news. "There are not two sides defined by a wall. This is one landscape, divided," Rael says.
