How urban spaces can preserve history and build community | Walter Hood
00:14:14
Can public spaces both reclaim the past and embrace the future? Landscape architect Walter Hood has explored this question over the course of an iconic career, with projects ranging from Lafayette Square Park in San Francisco to the upcoming International African American Museum in Charleston, South Carolina. In this inspiring talk packed with images of his work, Hood shares the five simple concepts that guide his approach to creating spaces that illuminate shared memories and force us to look at one another in a different way.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/i5zpON5h9lQ" height="1" width="1" alt=""/>

How cancer cells communicate -- and how we can slow them down | Hasini Jayatilaka
00:10:19
When cancer cells are closely packed together in a tumor, they're able to communicate with each other and coordinate their movement throughout the body. What if we could interrupt this process? In this accessible talk about cutting-edge science, Hasini Jayatilaka shares her work on an innovative method to stop cancer cells from communicating -- and halt their fatal ability to spread.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/-Zni3gWQOWw" height="1" width="1" alt=""/>

What a scrapyard in Ghana can teach us about innovation | DK Osseo-Asare
00:14:17
In Agbogbloshie, a community in Accra, Ghana, people descend on a scrapyard to mine electronic waste for recyclable materials. Without formal training, these urban miners often teach themselves the workings of electronics by taking them apart and putting them together again. Designer DK Osseo-Asare wondered: What would happen if we connected these self-taught techies with students and young professionals in STEAM fields? The result: a growing maker community where people engage in peer-to-peer, hands-on education, motivated by what they want to create. Learn more about how this African makerspace is pioneering a grassroots circular economy.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/QoowR5dbnCE" height="1" width="1" alt=""/>

Why I fight for the education of refugee girls (like me) | Mary Maker
00:16:47
After fleeing war-torn South Sudan as a child, Mary Maker found security and hope in the school at Kenya's Kakuma Refugee Camp. Now a teacher of young refugees herself, she sees education as an essential tool for rebuilding lives -- and empowering a generation of girls who are too often denied entrance into the classroom. "For the child of war, an education can turn their tears of loss into a passion for peace," Maker says.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/XV3DGzXBpBg" height="1" width="1" alt=""/>

You may be accidentally investing in cigarette companies | Bronwyn King
00:14:38
Tobacco causes more than seven million deaths every year -- and many of us are far more complicit in the problem than we realize. In a bold talk, oncologist Dr. Bronwyn King tells the story of how she uncovered the deep ties between the tobacco industry and the entire global finance sector, which invests our money in cigarette companies through big banks, insurers and pension funds. Learn how Dr. King has ignited a worldwide movement to create tobacco-free investments and how each of us can play a role in ending this epidemic.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/VVmMJlH_11o" height="1" width="1" alt=""/>

How to stop swiping and find your person on dating apps | Christina Wallace
00:05:19
Let's face it, online dating can suck. So many potential people, so much time wasted -- is it even worth it? Podcaster and entrepreneur Christina Wallace thinks so, if you do it right. In a funny, practical talk, Wallace shares how she used her MBA skill set to invent a "zero date" approach and get off swipe-based apps -- and how you can, too.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/SMz8rN8qM9Y" height="1" width="1" alt=""/>

How AI is making it easier to diagnose disease | Pratik Shah
00:04:59
Today's AI algorithms require tens of thousands of expensive medical images to detect a patient's disease. What if we could drastically reduce the amount of data needed to train an AI, making diagnoses low-cost and more effective? TED Fellow Pratik Shah is working on a clever system to do just that. Using an unorthodox AI approach, Shah has developed a technology that requires as few as 50 images to develop a working algorithm -- and can even use photos taken on doctors' cell phones to provide a diagnosis. Learn more about how this new way to analyze medical information could lead to earlier detection of life-threatening illnesses and bring AI-assisted diagnosis to more health care settings worldwide.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/za50rkHp_Cs" height="1" width="1" alt=""/>

Why doctors are offering free tax prep in their waiting rooms | Lucy Marcil
00:04:56
More than 90 percent of children in the US see a doctor at least once a year, which means countless hours spent in waiting rooms for parents. What if those hours could be used for something productive -- like saving money? Through her organization StreetCred, pediatrician and TED Fellow Lucy Marcil is offering free tax prep to parents right in the waiting room, reimagining what a doctor's visit can look like and helping to lift families out of poverty. Learn more about how free tax prep and guidance could be the best poverty prescription we have in the US.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/CCPn3JSK7c0" height="1" width="1" alt=""/>

Where are all the aliens? | Stephen Webb
00:13:18
The universe is incredibly old, astoundingly vast and populated by trillions of planets -- so where are all the aliens? Astronomer Stephen Webb has an explanation: we're alone in the universe. In a mind-expanding talk, he spells out the remarkable barriers a planet would need to clear in order to host an extraterrestrial civilization -- and makes a case for the beauty of our potential cosmic loneliness. "The silence of the universe is shouting, 'We're the creatures who got lucky,'" Webb says.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/Gv7sgxTTbK4" height="1" width="1" alt=""/>

What the Russian Revolution would have looked like on social media | Mikhail Zygar
00:04:49
History is written by the victors, as the saying goes -- but what would it look like if it was written by everyone? Journalist and TED Fellow Mikhail Zygar is on a mission to show us with Project1917, a "social network for dead people" that posts the real diaries and letters of more than 3,000 people who lived during the Russian Revolution. By showing the daily thoughts of the likes of Lenin, Trotsky and many less celebrated figures, the project sheds new light on history as it once was -- and as it could have been. Learn more about this digital retelling of the past as well as Zygar's latest project about the transformative year of 1968.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/veK27DBaze8" height="1" width="1" alt=""/>

What your smart devices know (and share) about you | Kashmir Hill and Surya Mattu
00:09:05
Once your smart devices can talk to you, who else are they talking to? Kashmir Hill and Surya Mattu wanted to find out -- so they outfitted Hill's apartment with 18 different internet-connected devices and built a special router to track how often they contacted their servers and see what they were reporting back. The results were surprising -- and more than a little bit creepy. Learn more about what the data from your smart devices reveals about your sleep schedule, TV binges and even your tooth-brushing habits -- and how tech companies could use it to target and profile you. (This talk contains mature language.)<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/ttbCIEvichc" height="1" width="1" alt=""/>

The power of diversity within yourself | Rebeca Hwang
00:09:44
Rebeca Hwang has spent a lifetime juggling identities -- Korean heritage, Argentinian upbringing, education in the United States -- and for a long time she had difficulty finding a place in the world to call home. Yet along with these challenges came a pivotal realization: that a diverse background is a distinct advantage in today's globalized world. In this personal talk, Hwang reveals the endless benefits of embracing our complex identities -- and shares her hopes for creating a world where identities aren't used to alienate but to bring people together instead.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/YIx3nbEAgKU" height="1" width="1" alt=""/>

The mission to create a searchable database of Earth's surface | Will Marshall
00:06:13
What if you could search the surface of the Earth the same way you search the internet? Will Marshall and his team at Planet use the world's largest fleet of satellites to image the entire Earth every day. Now they're moving on to a new project: using AI to index all the objects on the planet over time -- which could make ships, trees, houses and everything else on Earth searchable, the same way you search Google. He shares a vision for how this database can become a living record of the immense physical changes happening across the globe. "You can't fix what you can't see," Marshall says. "We want to give people the tools to see change and take action."<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/iTXKP4BfJ1Y" height="1" width="1" alt=""/>

The rapid growth of the Chinese internet -- and where it's headed | Gary Liu
00:12:41
The Chinese internet has grown at a staggering pace -- it now has more users than the combined populations of the US, UK, Russia, Germany, France and Canada. Even with its imperfections, the lives of once-forgotten populations have been irrevocably elevated because of it, says South China Morning Post CEO Gary Liu. In a fascinating talk, Liu details how the tech industry in China has developed -- from the innovative, like AI-optimized train travel, to the dystopian, like a social credit rating that both rewards and restricts citizens.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/k61E27fj9GQ" height="1" width="1" alt=""/>

The agony of opioid withdrawal -- and what doctors should tell patients about it | Travis Rieder
00:14:17
The United States accounts for five percent of the world's population but consumes almost 70 percent of the total global opioid supply, creating an epidemic that has resulted in tens of thousands of deaths each year. How did we get here, and what can we do about it? In this personal talk, Travis Rieder recounts the painful, often-hidden struggle of opioid withdrawal and reveals how doctors who are quick to prescribe (and overprescribe) opioids aren't equipped with the tools to eventually get people off the meds.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/Ly4em6JGpxk" height="1" width="1" alt=""/>

The symbols of systemic racism -- and how to take away their power | Paul Rucker
00:07:01
Multidisciplinary artist and TED Fellow Paul Rucker is unstitching the legacy of systemic racism in the United States. A collector of artifacts connected to the history of slavery -- from branding irons and shackles to postcards depicting lynchings -- Rucker couldn't find an undamaged Ku Klux Klan robe for his collection, so he began making his own. The result: striking garments in non-traditional fabrics like kente cloth, camouflage and silk that confront the normalization of systemic racism in the US. "If we as a people collectively look at these objects and realize that they are part of our history, we can find a way to where they have no more power over us," Rucker says.

What if we eliminated one of the world's oldest diseases? | Caroline Harper
00:10:12
Thousands of years ago, ancient Nubians drew pictures on tomb walls of a terrible disease that turns the eyelids inside out and causes blindness. This disease, trachoma, is still a scourge in many parts of the world today -- but it's also completely preventable, says Caroline Harper. Armed with data from a global mapping project, Harper's organization Sightsavers has a plan: to focus on countries where funding gaps stand in the way of eliminating the disease and ramp up efforts where the need is most severe. Learn more about their goal of consigning trachoma to the history books -- and how you can help. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/cs6wFnDOowY" height="1" width="1" alt=""/>

Writer and artist James Bridle uncovers a dark, strange corner of the internet, where unknown people or groups on YouTube hack the brains of young children in return for advertising revenue. From "surprise egg" reveals and the "Finger Family Song" to algorithmically created mashups of familiar cartoon characters in violent situations, these videos exploit and terrify young minds -- and they tell us something about where our increasingly data-driven world is headed. "We need to stop thinking about technology as a solution to all of our problems, but think of it as a guide to what those problems actually are, so we can start thinking about them properly and start to address them," Bridle says.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/dzws81n0CIo" height="1" width="1" alt=""/>

Why you should love gross science | Anna Rothschild
00:13:12
What can we learn from the slimy, smelly side of life? In this playful talk, science journalist Anna Rothschild shows us the hidden wisdom of "gross stuff" and explains why avoiding the creepy underbelly of nature, medicine and technology closes us off to important sources of knowledge about our health and the world. "When we explore the gross side of life, we find insights that we never would have thought we'd find, and we even often reveal beauty that we didn't think was there," Rothschild says.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/OL3EdMlA918" height="1" width="1" alt=""/>

How Netflix changed entertainment -- and where it's headed | Reed Hastings
00:20:51
Netflix changed the world of entertainment -- first with DVD-by-mail, then with streaming media and then again with sensational original shows like "Orange Is the New Black" and "Stranger Things" -- but not without taking its fair share of risks. In conversation with TED curator Chris Anderson, Netflix co-founder and CEO Reed Hastings discusses the company's bold internal culture, the powerful algorithm that fuels their recommendations, the $8 billion worth of content they're investing in this year and his philanthropic pursuits supporting innovative education, among much more.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/zda9wPVRBjc" height="1" width="1" alt=""/>

How we can bring mental health support to refugees | Essam Daod
00:05:26
The global refugee crisis is a mental health catastrophe, leaving millions in need of psychological support to overcome the traumas of dislocation and conflict. To undo the damage, child psychiatrist and TED Fellow Essam Daod has been working in camps, rescue boats and the shorelines of Greece and the Mediterranean Sea to help refugees (a quarter of which are children) reframe their experiences through short, powerful psychological interventions. "We can all do something to prevent this mental health catastrophe," Daod says. "We need to acknowledge that first aid is not just needed for the body, but it has also to include the mind, the soul."<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/S17jz6CjqYE" height="1" width="1" alt=""/>

Technology that knows what you're feeling | Poppy Crum
00:12:42
What happens when technology knows more about us than we do? Poppy Crum studies how we express emotions -- and she suggests the end of the poker face is near, as new tech makes it easy to see the signals that give away how we're feeling. In a talk and demo, she shows how "empathetic technology" can read physical signals like body temperature and the chemical composition of our breath to inform on our emotional state. For better or for worse. "If we recognize the power of becoming technological empaths, we get this opportunity where technology can help us bridge the emotional and cognitive divide," Crum says.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/V49G5BVSWD0" height="1" width="1" alt=""/>

The surprising science of alpha males | Frans de Waal
00:15:54
In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/UocfRyUm8xo" height="1" width="1" alt=""/>

Four billion years of evolution in six minutes | Prosanta Chakrabarty
00:05:41
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."<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/XBIvLOzwuug" height="1" width="1" alt=""/>

Why the secret to success is setting the right goals | John Doerr

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.

In this powerful talk, Eustis outlines his plan to reach (and listen to) people in places across the US where the theater, like many other institutions, has turned its back -- like the deindustrialized Rust Belt. "Our job is to try to hold up a vision to America that shows not only who all of us are individually, but that welds us back into the commonality that we need to be," Eustis says.

What it takes to be racially literate | Priya Vulchi and Winona Guo
00:12:22
Over the last year, Priya Vulchi and Winona Guo traveled to all 50 US states, collecting personal stories about race and intersectionality. Now they're on a mission to equip every American with the tools to understand, navigate and improve a world structured by racial division. In a dynamic talk, Vulchi and Guo pair the personal stories they've collected with research and statistics to reveal two fundamental gaps in our racial literacy -- and how we can overcome them.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/RWxDqZeSno0" height="1" width="1" alt=""/>

How to build (and rebuild) trust | Frances Frei
00:15:05
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.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/nHgzPe4yEZc" height="1" width="1" alt=""/>

Why you don't like the sound of your own voice | Rébecca Kleinberger
00:12:42
Your voice is indistinguishable from how other people see you, but your relationship with it is far from obvious. Rébecca Kleinberger studies how we use and understand our voices and the voices of others. She explains why you may not like the sound of your own voice on recordings, the differences between your outward, inward and inner voices -- and the extraordinary things you communicate without being aware of it.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/mQeTAO_FVUU" height="1" width="1" alt=""/>

It's time for the law to protect victims of gender violence | Laura L. Dunn
00:06:13
To make accountability the norm after gender violence in the United States, we need to change tactics, says victims' rights attorney and TED Fellow Laura L. Dunn. Instead of going institution by institution, fighting for reform, we need to go to the Constitution and finally pass the Equal Rights Amendment, which would require states to address gender inequality and violence. By ushering in sweeping change, Dunn says, "our legal system can become a system of justice, and #MeToo can finally become 'no more.'"<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/B-yHMxBLcK0" height="1" width="1" alt=""/>

Is the world getting better or worse? A look at the numbers | Steven Pinker
00:18:32
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."<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/2HeG6GbpVUk" height="1" width="1" alt=""/>

How I turn negative online comments into positive offline conversations | Dylan Marron
00:10:52
Digital creator Dylan Marron has racked up millions of views for projects like "Every Single Word" and "Sitting in Bathrooms With Trans People" -- but he's found that the flip side of success online is internet hate. Over time, he's developed an unexpected coping mechanism: calling the people who leave him insensitive comments and asking a simple question: "Why did you write that?" In a thoughtful talk about how we interact online, Marron explains how sometimes the most subversive thing you can do is actually speak with people you disagree with, not simply at them.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/ZnruJLpdCCM" height="1" width="1" alt=""/>

00:04:27
In the ongoing debate over refugees, we hear from everyone -- from politicians who pledge border controls to citizens who fear they'll lose their jobs -- everyone, that is, except migrants themselves. Why are they coming? Journalist and TED Fellow Yasin Kakande explains what compelled him and many others to flee their homelands, urging a more open discussion and a new perspective. Because humanity's story, he reminds us, is a story of migration: "There are no restrictions that could ever be so rigorous to stop the wave of migration that has determined our human history," he says.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/hHrO7NuRM30" height="1" width="1" alt=""/>

What if we ended the injustice of bail? | Robin Steinberg
00:14:24
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 plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/oK5Ky6urmp4" height="1" width="1" alt=""/>

How we need to remake the internet | Jaron Lanier
00:14:54
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.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/UMNxGGLXiH0" height="1" width="1" alt=""/>

How language shapes the way we think | Lera Boroditsky

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.

But we can get smarter about the way we make, and remake, our products.

Learn more about the "adjacent possible" -- the crossroads of what's actual and what's possible -- and how studying the math that drives it could explain how we create new ideas.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/nf4PuFvkZew" height="1" width="1" alt=""/>

A rite of passage for late life | Bob Stein
00:05:53
We use rituals to mark the early stages of our lives, like birthdays and graduations -- but what about our later years? In this meditative talk about looking both backward and forward, Bob Stein proposes a new tradition of giving away your things (and sharing the stories behind them) as you get older, to reflect on your life so far and open the door to whatever comes next.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/Fz2JHQ-ZAIM" height="1" width="1" alt=""/>

What if gentrification was about healing communities instead of displacing them? | Liz Ogbu
00:15:01
Liz Ogbu is an architect who works on spatial justice: the idea that justice has a geography and that the equitable distribution of resources and services is a human right. In San Francisco, she's questioning the all too familiar story of gentrification: that poor people will be pushed out by development and progress. "Why is it that we treat culture erasure and economic displacement as inevitable?" she asks, calling on developers, architects and policymakers to instead "make a commitment to build people's capacity to stay in their homes, to stay in their communities, to stay where they feel whole."<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/nxJsPDOlhC0" height="1" width="1" alt=""/>

How I use art to bridge misunderstanding | Adong Judith
00:05:00
Director and playwright Adong Judith creates provocative art that sparks dialogue on issues from LGBTQ rights to war crimes. In this quick but powerful talk, the TED Fellow details her work -- including the play "Silent Voices," which brought victims of the Northern Ugandan war against Joseph Kony's rebel group together with political, religious and cultural leaders for transformative talks. "Listening to one another will not magically solve all problems," Judith says. "But it will give a chance to create avenues to start to work together to solve many of humanity's problems."<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/ZqJEkEhHQmI" height="1" width="1" alt=""/>

Can I have your brain? The quest for truth on concussions and CTE | Chris Nowinski
00:11:20
Something strange and deadly is happening inside the brains of top athletes -- a degenerative condition, possibly linked to concussions, that causes dementia, psychosis and far-too-early death. It's called chronic traumatic encephalopathy, or CTE, and it's the medical mystery that Chris Nowinski wants to solve by analyzing brains after death. It's also why, when Nowinski meets a pro athlete, his first question is: "Can I have your brain?" Hear more from this ground-breaking effort to protect athletes' brains -- and yours, too.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/HiYk3FYnjZM" height="1" width="1" alt=""/>

What we can do about the culture of hate | Sally Kohn

We're all against hate, right? We agree it's a problem -- their problem, not our problem, that is. But as Sally Kohn discovered, we all hate -- some of us in subtle ways, others in obvious ones. As she confronts a hard story from her own life, she shares ideas on how we can recognize, challenge and heal from hatred in our institutions and in ourselves.<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/PKSuBtB3yuo" height="1" width="1" alt=""/>

The Great Migration and the power of a single decision | Isabel Wilkerson
00:17:55
Sometimes, a single decision can change the course of history. Join journalist and author Isabel Wilkerson as she tells the story of the Great Migration, the outpouring of six million African Americans from the Jim Crow South to cities in the North and West between World War I and the 1970s. This was the first time in American history that the lowest caste people signaled they had options and were willing to take them -- and the first time they had a chance to choose for themselves what they would do with their innate talents, Wilkerson explains. "These people, by their actions, were able to do what the powers that be, North and South, could not or would not do," she says. "They freed themselves."<img src="http://feeds.feedburner.com/~r/TedtalksHD/~4/q65-Wy3dQFY" height="1" width="1" alt=""/>
