(This ambitious plan is part of the Audacious Project, TED's initiative to inspire and fund global change.)
Theoretical physicist David Deutsch delivers a mind-bending meditation on the "great monotony" -- the idea that nothing novel has appeared in the universe for billions of years -- and shows how humanity's capacity to create explanatory knowledge could be the thing that bucks this trend. "Humans are not playthings of cosmic forces," he says. "We are users of cosmic forces."
"Human beings are works in progress that mistakenly think they're finished." Dan Gilbert shares recent research on a phenomenon he calls the "end of history illusion," where we somehow imagine that the person we are right now is the person we'll be for the rest of time. Hint: that's not the case.
Most of us know Bruce Lee as the famous martial artist and action film star -- but he was also a philosopher who taught "self-actualization": the practice of how to be yourself in the best way possible. In this inspiring talk, Bruce's daughter Shannon Lee takes us inside the mind of her father, exploring how to use his philosophy in your daily life to achieve profound personal growth and make a lasting impact.

Learn how an ancient rock found near a hot volcanic pool is shifting our understanding of the origin-of-life puzzle.
Traditional thinking on corruption goes like this: if you put good laws in place and enforce them well, then economic development increases and corruption falls. In reality, we have the equation backwards, says innovation researcher Efosa Ojomo. In this compelling talk, he offers new thinking on how we could potentially eliminate corruption worldwide by focusing on one thing: scarcity. "Societies don't develop because they've reduced corruption," he says. "They're able to reduce corruption because they've developed."
With fascinating research and hilarious anecdotes, neuroscientist Camilla Arndal Andersen takes us into the lab where she studies people's sense of taste via brain scans. She reveals surprising insights about the way our brains subconsciously experience food -- and shows how this data could help us eat healthier without sacrificing taste.
The US health care system assumes many things about patients: that they can take off from work in the middle of the day, speak English, have a working telephone and a steady supply of food. Because of that, it's failing many of those who are most in need, says Mitchell Katz, CEO of the largest public health care system in the US. In this eye-opening talk, he shares stories of the challenges low-income patients face -- and how we can build a better system for all.

Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we're a small part of a complex, four-billion-year process -- and not the end of the line. "We're not the goal of evolution," Chakrabarty says. "Think of us all as young leaves on this ancient and gigantic tree of life -- connected by invisible branches not just to each other, but to our extinct relatives and our evolutionary ancestors."
Tobacco causes more than seven million deaths every year -- and many of us are far more complicit in the problem than we realize.

"Positivity is something worth fighting for, and the fight is not with others -- it's internal," Thomas says. "If you want to make positive changes in your life, you have to consistently be positive."
Can technology make people safer from threats like violent extremism, censorship and persecution? In this illuminating talk, technologist Yasmin Green details programs pioneered at Jigsaw (a unit within Alphabet Inc., the collection of companies that also includes Google) to counter radicalization and online harassment -- including a project that could give commenters real-time feedback about how their words might land, which has already increased spaces for dialogue. "If we ever thought that we could build an internet insulated from the dark side of humanity, we were wrong," Green says. "We have to throw our entire selves into building solutions that are as human as the problems they aim to solve."
"For all that's ever been said about climate change, we haven't heard nearly enough about the psychological impacts of living in a warming world," says science writer Britt Wray.

Learn how Kleinrock teaches kids to discuss taboo topics without fear -- because the best way to start solving social problems is to talk about them.
In the US, the very same blood test can cost $19 at one clinic and $522 at another clinic just blocks away -- and nobody knows the difference until they get a bill weeks later. Journalist Jeanne Pinder says it doesn't have to be this way. She's built a platform that crowdsources the true costs of medical procedures and makes the data public, revealing the secrets of health care pricing. Learn how knowing what stuff costs in advance could make us healthier, save us money -- and help fix a broken system.
Roy Bahat was worried. His company invests in new technology like AI to make businesses more efficient -- but, he wondered, what was AI doing to the people whose jobs might change, go away or become less fulfilling?

Learn three ways we can each work to be more civil -- and start talking about our differences with respect.
Modern American health care is defined by its high costs, high overhead and inaccessibility -- especially for low-income patients. What if we could redesign the system to serve the poor and still have doctors make money? In an eye-opening (and surprisingly funny) talk, physician P.J. Parmar shares the story of the clinic he founded in Colorado, where he serves only resettled refugees who mostly use Medicaid, and makes the business case for a fresh take on medical service.

J.D. Vance grew up in a small, poor city in the Rust Belt of southern Ohio, where he had a front-row seat to many of the social ills plaguing America: a heroin epidemic, failing schools, families torn apart by divorce and sometimes violence. In a searching talk that will echo throughout the country's working-class towns, the author details what the loss of the American Dream feels like and raises an important question that everyone from community leaders to policy makers needs to ask: How can we help kids from America's forgotten places break free from hopelessness and live better lives?
There's no better way to stop a disease than to catch and treat it early, before symptoms occur. That's the whole point of medical screening techniques like radiography, MRIs and blood tests. But there's one medium with overlooked potential for medical analysis: your breath. Technologist Julian Burschka shares the latest in the science of breath analysis -- the screening of the volatile organic compounds in your exhaled breath -- and how it could be used as a powerful tool to detect, predict and ultimately prevent disease.
You know the "forgotten middle": they're the students, coworkers and regular people who are often overlooked because they're seen as neither exceptional nor problematic. How can we empower them to reach their full potential? Sharing her work helping young people get to and through college, social activist Danielle R. Moss challenges us to think deeper about who deserves help and attention -- and shows us how to encourage those in the middle to dream big.

In this frank, eye-opening talk, she shows how a flawed understanding of the female body has shaped this discussion for centuries. She debunks some age-old myths (you're welcome) and offers a richer definition of pleasure that gets closer to the simple truth about women's sexuality.
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.

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.
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.

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.
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.
If we hope to heal the racial tensions that threaten to tear the fabric of society apart, we're going to need the skills to openly express ourselves in racially stressful situations.

In this visionary talk, Richards calls for a global political revolution for women's equality and offers her ideas for how we can build it.
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.
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.
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.
Around the world, black girls are being pushed out of schools because of policies that target them for punishment, says author and social justice scholar Monique W. Morris. The result: countless girls are forced into unsafe futures with restricted opportunities. How can we put an end to this crisis? 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.

As a fire chief and first responder, Jan Rader has spent her career saving lives. But when the opioid epidemic hit her town, she realized they needed to take a brand-new approach to life-saving. In this powerful, hopeful talk, Rader shows what it's like on the front lines of this crisis -- and how her community is taking an unusual new approach to treating substance-abuse disorder that starts with listening.
Our leaders and institutions are failing us, but it's not always because they're bad or unethical, says venture capitalist John Doerr -- often, it's simply because they're leading us toward the wrong objectives. In this practical talk, Doerr shows us how we can get back on track with "Objectives and Key Results," or OKRs -- a goal-setting system that's been employed by the likes of Google, Intel and Bono to set and execute on audacious goals. Learn more about how setting the right goals can mean the difference between success and failure -- and how we can use OKRs to hold our leaders and ourselves accountable.
There are about 7,000 languages spoken around the world -- and they all have different sounds, vocabularies and structures. But do they shape the way we think? Cognitive scientist Lera Boroditsky shares examples of language -- from an Aboriginal community in Australia that uses cardinal directions instead of left and right to the multiple words for blue in Russian -- that suggest the answer is a resounding yes. "The beauty of linguistic diversity is that it reveals to us just how ingenious and how flexible the human mind is," Boroditsky says. "Human minds have invented not one cognitive universe, but 7,000."
Can you look at someone's face and know what they're feeling? Does everyone experience happiness, sadness and anxiety the same way? What are emotions anyway? For the past 25 years, psychology professor Lisa Feldman Barrett has mapped facial expressions, scanned brains and analyzed hundreds of physiology studies to understand what emotions really are. She shares the results of her exhaustive research -- and explains how we may have more control over our emotions than we think.
In the early days of digital culture, Jaron Lanier helped craft a vision for the internet as public commons where humanity could share its knowledge -- but even then, this vision was haunted by the dark side of how it could turn out: with personal devices that control our lives, monitor our data and feed us stimuli. (Sound familiar?) In this visionary talk, Lanier reflects on a "globally tragic, astoundingly ridiculous mistake" companies like Google and Facebook made at the foundation of digital culture -- and how we can undo it. "We cannot have a society in which, if two people wish to communicate, the only way that can happen is if it's financed by a third person who wishes to manipulate them," he says.
In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" -- raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar.
At some point in our lives, almost every one of us will have our heart broken. Imagine how different things would be if we paid more attention to this unique emotional pain. Psychologist Guy Winch reveals how recovering from heartbreak starts with a determination to fight our instincts to idealize and search for answers that aren't there -- and offers a toolkit on how to, eventually, move on. Our hearts might sometimes be broken, but we don't have to break with them.
Trust is the foundation for everything we do. But what do we do when it's broken? In an eye-opening talk, Harvard Business School professor Frances Frei gives a crash course in trust: how to build it, maintain it and rebuild it -- something she worked on during a recent stint at Uber. "If we can learn to trust one another more, we can have unprecedented human progress," Frei says.
Who deserves to be in a museum? For too long, the answer has been "the extraordinary" -- those aspirational historymakers who inspire us with their successes. But those stories are limiting, says museum curator Ariana Curtis. In a visionary talk, she imagines how museums can more accurately represent history by honoring the lives of people both extraordinary and everyday, prominent and hidden -- and amplify diverse perspectives that should have always been included.
Women own 39 percent of all businesses in the US, but female entrepreneurs get only two percent of venture funding. What's causing this gap? Dana Kanze shares research suggesting that it might be the types of questions start-up founders get asked when they're invited to pitch. Whether you're starting a new business or just having a conversation, learn how to spot the kinds of questions you're being asked -- and how to respond more effectively.
Sir Ken Robinson makes an entertaining and profoundly moving case for creating an education system that nurtures (rather than undermines) creativity.
Hard work, resilience and grit lead to success, right? This narrative pervades the way we think, says economist Darrick Hamilton, but the truth is that our chances at economic security have less to do with what we do and more to do with the wealth position we're born into. Enter "baby bonds": trust accounts of up to $60,000 for every newborn, calibrated to the wealth of their family. Learn how this bold proposal could help us reduce inequality -- and give every child personal seed money for important things like going to college, buying a home or starting a business. "Without capital, inequality is locked in," Hamilton says. "When it comes to economic security, wealth is both the beginning and the end."
In a powerful talk, educator Eldra Jackson III shares how he unlearned dangerous lessons about masculinity through Inside Circle, an organization that leads group therapy for incarcerated men.

Using examples from vacations to colonoscopies, Nobel laureate and founder of behavioral economics Daniel Kahneman reveals how our "experiencing selves" and our "remembering selves" perceive happiness differently. This new insight has profound implications for economics, public policy -- and our own self-awareness.
How do you talk to someone who doesn't believe in climate change? Not by rehashing the same data and facts we've been discussing for years, says climate scientist Katharine Hayhoe. In this inspiring, pragmatic talk, Hayhoe shows how the key to having a real discussion is to connect over shared values like family, community and religion -- and to prompt people to realize that they already care about a changing climate. "We can't give in to despair," she says. "We have to go out and look for the hope we need to inspire us to act -- and that hope begins with a conversation, today."
Humans are no longer valued for our creativity, says media theorist Douglas Rushkoff -- in a world dominated by digital technology, we're now just valued for our data. In a passionate talk, Rushkoff urges us to stop using technology to optimize people for the market and start using it to build a future centered on our pre-digital values of connection, creativity and respect. "Join 'Team Human.' Find the others," he says. "Together let's make the future that we always wanted."
The workplace is often presented as a meritocracy, where you can succeed by putting your head down and working hard. Wall Street veteran Carla Harris learned early in her career that this a myth. The key to actually getting ahead? Get a sponsor: a person who will speak on your behalf in the top-level, closed-door meetings you're not invited to (yet). Learn how to identify and develop a productive sponsor relationship in this candid, powerful talk.
Imagine your company hires a new employee and then everyone just ignores them, day in and day out, while they sit alone at their desk getting paid to do nothing. This situation actually happens all the time -- when companies invest millions of dollars in new tech tools only to have frustrated employees disregard them, says Nadjia Yousif. In this fun and practical talk, she offers advice on how to better collaborate with the technologies in your workplace -- by treating them like colleagues.
What shapes our perceptions (and misperceptions) about science? In an eye-opening talk, meteorologist J. Marshall Shepherd explains how confirmation bias, the Dunning-Kruger effect and cognitive dissonance impact what we think we know -- and shares ideas for how we can replace them with something much more powerful: knowledge.
When a parent is sent to prison, the unintended victims of their crimes are their own children -- without stability and support, kids are at higher risk for mental health and development issues. In a heartfelt talk, Alan Crickmore explains how the charity Storybook Dads is keeping families connected through the simple act of storytelling.
Domestic workers are entrusted with the most precious aspects of people's lives -- they're the nannies, the elder-care workers and the house cleaners who do the work that makes all other work possible. Too often, they're invisible, taken for granted or dismissed as "help," yet they continue to do their wholehearted best for the families and homes in their charge. In this sensational talk, activist Ai-Jen Poo shares her efforts to secure equal rights and fair wages for domestic workers and explains how we can all be inspired by them. "Think like a domestic worker who shows up and cares no matter what," she says.
Two hundred million years ago, our mammal ancestors developed a new brain feature: the neocortex. This stamp-sized piece of tissue (wrapped around a brain the size of a walnut) is the key to what humanity has become. Now, futurist Ray Kurzweil suggests, we should get ready for the next big leap in brain power, as we tap into the computing power in the cloud.
How can we get people to do more good: to go to the polls, give to charity, conserve resources or just generally act better towards others? MIT research scientist Erez Yoeli shares a simple checklist for harnessing the power of reputations -- or our collective desire to be seen as generous and kind instead of selfish -- to motivate people to act in the interest of others. Learn more about how small changes to your approach to getting people to do good could yield surprising results.
How you respond after setbacks is what defines your character. Stacey Abrams was the first black woman in the history of the United States to be nominated by a major party for governor -- she lost that hotly contested race, but as she says: the only choice is to move forward. In an electrifying talk, she shares the lessons she learned from her campaign for governor of Georgia, some advice on how to change the world -- and a few hints at her next steps. "Be aggressive about your ambition," Abrams says.
Think about the most tired you've ever been at work. It probably wasn't when you stayed late or came home from a road trip -- chances are it was when you had someone looking over your shoulder, watching your each and every move. "If we know that micromanagement isn't really effective, why do we do it?" asks entrepreneur Chieh Huang. In a funny talk packed with wisdom and humility, Huang shares the cure for micromanagement madness -- and how to foster innovation and happiness at work.
The subject of race can be very touchy. As finance executive Mellody Hobson says, it's a "conversational third rail." But, she says, that's exactly why we need to start talking about it. In this engaging, persuasive talk, Hobson makes the case that speaking openly about race — and particularly about diversity in hiring -- makes for better businesses and a better society.
In 2006, Tarana Burke was consumed by a desire to do something about the sexual violence she saw in her community. She took out a piece of paper, wrote "Me Too" across the top and laid out an action plan for a movement centered on the power of empathy between survivors. More than a decade later, she reflects on what has since become a global movement -- and makes a powerful call to dismantle the power and privilege that are building blocks of sexual violence. "We owe future generations nothing less than a world free of sexual violence," she says. "I believe we can build that world."
With Marvel's "America Chavez," Gabby Rivera wrote a new kind of superhero -- one who can punch portals into other dimensions while also embracing her gentle, goofy, soft side. In a funny, personal talk, Rivera shares how her own childhood as a queer Puerto Rican in the Bronx informed this new narrative -- and shows images from the comic book that reveal what happens when a superhero embraces her humanity. As she says: "That myth of having to go it alone and be tough is not serving us."
What if we took out more greenhouse gases than we put into the atmosphere? This hypothetical scenario, known as "drawdown," is our only hope of averting climate disaster, says strategist Chad Frischmann. In a forward-thinking talk, he shares solutions to climate change that exist today -- conventional tactics like the use of renewable energy and better land management as well as some lesser-known approaches, like changes to food production, better family planning and the education of girls. Learn more about how we can reverse global warming and create a world where regeneration, not destruction, is the rule.
Tech that can decode your brain activity and reveal what you're thinking and feeling is on the horizon, says legal scholar and ethicist Nita Farahany. What will it mean for our already violated sense of privacy? In a cautionary talk, Farahany warns of a society where people are arrested for merely thinking about committing a crime (like in "Minority Report") and private interests sell our brain data -- and makes the case for a right to cognitive liberty that protects our freedom of thought and self-determination.
Every cell that's ever lived has been the result of the four-letter genetic alphabet: A, T, C and G -- the basic units of DNA. But now that's changed. In a visionary talk, synthetic biologist Floyd E. Romesberg introduces us to the first living organisms created with six-letter DNA -- the four natural letters plus two new man-made ones, X and Y -- and explores how this breakthrough could challenge our basic understanding of nature's design.
On any given night, more than 450,000 people in the United States are locked up in jail simply because they don't have enough money to pay bail. The sums in question are often around $500: easy for some to pay, impossible for others. This has real human consequences -- people lose jobs, homes and lives, and it drives racial disparities in the legal system. Robin Steinberg has a bold idea to change this. In this powerful talk, she outlines the plan for The Bail Project -- an unprecedented national revolving bail fund to fight mass incarceration. (This ambitious idea is part of the Audacious Project, TED's initiative to inspire and fund global change.)
As a writer, Elizabeth Gilbert is notorious for placing her heart squarely on her sleeve. Her best-selling memoir "Eat Pray Love" was a sensation precisely because of her eloquent, open-hearted descriptions of fear, divorce and wanting everything life had to offer. When she spoke at TED back in 2009, she charmed the audience with her frank descriptions of what happened after the book became a runaway success and her lyrical ideas of the nature of creativity. Nearly ten years later, in this extraordinarily intimate conversation with TED curator Chris Anderson, she shares why openness, transparency and creativity are still central to her philosophy of life -- even when faced with moments of desperation and personal tragedy.
Do you ever order clothes online in different sizes and colors, just to try them on and then send back what doesn't work? Aparna Mehta used to do this all time, until she one day asked herself: Where do all these returned clothes go? In an eye-opening talk, she reveals the unseen world of "free" online returns -- which, instead of ending up back on the shelf, are sent to landfills by the billions of pounds each year -- and shares a plan to help put an end to this growing environmental catastrophe.
Our oceans are unexplored and undersampled -- today, we still know more about other planets than our own. How can we get to a better understanding of this vast, important ecosystem? Explorer Sebastien de Halleux shares how a new fleet of wind- and solar-powered drones is collecting data at sea in unprecedented detail, revealing insights into things like global weather and the health of fish stocks. Learn more about what a better grasp of the ocean could mean for us back on land.
Some days, it feels like the only thing we can agree on is that we can't agree -- on anything. Drawing on her background as a world debate champion, Julia Dhar offers three techniques to reshape the way we talk to each other so we can start disagreeing productively and finding common ground -- over family dinners, during work meetings and in our national conversations.
Was 2017 really the "worst year ever," as some would have us believe? In his analysis of recent data on homicide, war, poverty, pollution and more, psychologist Steven Pinker finds that we're doing better now in every one of them when compared with 30 years ago. But progress isn't inevitable, and it doesn't mean everything gets better for everyone all the time, Pinker says. Instead, progress is problem-solving, and we should look at things like climate change and nuclear war as problems to be solved, not apocalypses in waiting. "We will never have a perfect world, and it would be dangerous to seek one," he says. "But there's no limit to the betterments we can attain if we continue to apply knowledge to enhance human flourishing."
Libraries have the power to create a better world; they connect communities, promote literacy and spark lifelong learners. But there's one thing that keeps people away: the fear of overdue book fines. In this thought-provoking talk, librarian Dawn Wacek makes the case that fines don't actually do what we think they do. What if your library just ... stopped asking for them altogether?
What exactly is civility, and what does it require? In a talk packed with historical insights, political theorist Teresa Bejan explains how civility has been used as both the foundation of tolerant societies and as a way for political partisans to silence and dismiss opposing views. Bejan suggests that we should instead try for "mere civility": the virtue of being able to disagree fundamentally with others without destroying the possibility of a common life tomorrow. (This talk contains mature language.)
Author AJ Jacobs embarked on a quest with a deceptively simple idea at its heart: to personally thank every person who helped make his morning cup of coffee. More than one thousand "thank yous" later, Jacobs reflects on the globe-trotting journey that ensued -- and shares the life-altering wisdom he picked up along the way.
