How Old Cell Phones Are Protecting the Rainforest

Planted high in jungle treetops, used cell phones powered by small solar panels record and upload the surrounding sounds of the landscape. In real-time, the audio is analyzed by AI software that can recognize chainsaws, logging trucks, and other signs of illegal logging nearby and notify locals of the problem. This project by Rainforest Connection is helping to put a stop to illegal logging in Indonesia and 11 other countries.

The Rainforest Connection System, the RFCx platform really is a full, end to end type solution, it all begins with what we call a guardian, which are ostensibly more or less, phones in boxes up in the treetops.

They have solar panels, so they can last for years, they charge themselves in the daytime and they run 24 hours a day. They capture all the sound of the forest, they package it up and send it up to the cloud in real-time over the cellphone network.

Once it’s in the cloud, we can run any number of artificial intelligence models on it, we can pick out chainsaws, gunshots, trucks, etc. Then in real-time, we can take those alerts and send them right back to people on the ground through software that we build called the Ranger App and through these web dashboards.

Rainforest Connection Taps High-Tech To Thwart Illegal Logging
“They can come here and catch the people in the act. That’s the powerful result of this system, because normally you arrive, and the trees are gone. You don’t know who did it and when they did it. But this system allows us to actually identify the threats and act in real time.”

What AI Hears in the Rainforest
“As it turns out, the best way to track people who are cutting down trees is sound. Using old cell phones linked to an artificial-intelligence platform in the cloud, White developed a system that can detect chainsaws in real time and send automated alerts to authorities.”

Illegal logging | WWF
“The global trade in roundwood, paper, furniture, and other products originating from illegally extracted timber is a multi-million dollar industry… Timber that is logged without payment of duties and taxes pushes down the market price of timber, which acts as an incentive for other loggers to follow the same practice. This further increases losses to governments and starts a vicious cycle in the market.”

Across the globe, elephants are poached for their tusks, pangolins for their scales, and totoaba fish for their bladders. Tackling the fourth largest crime industry in the world isn’t easy, but biologists, roboticists, detectives and even NASA scientists are getting creative in the hopes of making a difference. In this Seeker series, we’ll investigate true stories of wildlife crime and meet the people who are working to protect the world’s most endangered and persecuted animals.

The world’s biggest battery looks nothing like a battery

Discover the world’s biggest battery and explore how inventors are creating other giant batteries to help power the world— sustainably.

As of 2020, the world’s biggest lithium-ion battery is hooked up to the Southern California power grid and can provide enough power for about 250,000 homes. But it’s actually not the biggest battery in the world: a pair of lakes are. How can lakes be a battery? Explore how inventors are rethinking what a battery can be, and how these surprising solutions could help us achieve a sustainable future.

Understanding the history of ‘blackface’ — and why it’s so harmful | Dwan Reece | TEDxMidAtlantic

Throughout history, portrayals of characters in ‘blackface’ — with white people made up to caricature Black stereotypes — have been used in ways that demean, denigrate, and trivialize people of African descent. Dwan Reece, Curator of Music and Performing Arts at the Smithsonian’s National Museum of African American History Culture, offers a detailed history of this practice, and how it is still so harmful when it appears today. Dwandalyn (Dwan) Reece is a musician, scholar and museum professional who is Curator of Music and Performing Arts at the Smithsonian’s National Museum of African American History Culture. Responsible for the acquisition, research and interpretation of the museum’s music and performing arts collection, she curated the museum’s permanent exhibition, Musical Crossroads, for which she received the Secretary’s Research Prize in 2017.

Dwan’s other projects include the museum’s three-day Grand Opening Festival, Freedom Sounds: A Community Celebration and the Center for Folklife and Cultural Heritage’s 2011 Folklife Festival program, Rhythm & Blues: Tell it Like It Is. She serves as chair of the SI pan-institutional group, Smithsonian Music, and is co-curator of the 2019 initiative, the Smithsonian Year of Music.

Other projects include the forthcoming, Smithsonian Anthology of Hip-Hop and Rap and a book on the material culture of African American music. A resident of the Washington, DC metropolitan area for the last nineteen years, Dwan’s work at the museum and within her local community focuses on exploring the arts within a social, cultural and historical context. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Business revolution: What is the membership economy? | Robbie Kellman Baxter | Big Think

Business revolution: What is the membership economy?
Watch the newest video from Big Think: https://bigth.ink/NewVideo
Join Big Think Edge for exclusive videos: https://bigth.ink/Edge
———————————————————————————-
“I think that the membership economy is having as big an impact on business as the industrial revolution,” says Silicon Valley consultant Robbie Kellman Baxter.

Memberships or subscriptions fundamentally change the relationship between the consumer and the brand by delivering what Baxter calls a “forever promise.” The famous example of Blockbuster vs. Netflix illustrates this perfectly.

Subscriptions are not a new idea. Charles Dickens released his books to subscribers one chapter at a time, as he wrote them. What’s different today is technology and the speed at which even a one-person business can reach a huge number of customers.
———————————————————————————-
ROBBIE KELLMAN BAXTER

Based in Silicon Valley, Robbie is the author of The Membership Economy: Find Your Superusers, Master the Forever Transaction & Build Recurring Revenue (McGraw-Hill 2015), andThe Forever Transaction: How to Build a Business So Compelling, Your Customers Will Never Want to Leave (McGraw-Hill 2020). Robbie’s expertise extends to include SaaS, media, consumer products and retail and community organizations. Clients have included Microsoft, Fitbit and the Wall Street Journal.
———————————————————————————-
TRANSCRIPT: The membership economy is a term that I coined to describe what I was seeing starting about 15 years ago when I was working with Netflix and continuing into this massive transformational trend where companies of all types were moving from a model that focuses on ownership to access, from the transactional to the relational, from anonymous to known, from one payment to many smaller payments and from the organization talking at the customer and hoping they’re listening to multidirectional communication among customers and back and forth between the customers and the organization under the brand umbrella of the organization. So when you put all of those things together you have this kind of painter’s palette to reinvent your business model and that’s what’s driving this membership economy.

So membership isn’t a new concept. We have been joining things for as long as there have been humans. We joined clans or tribes. We’ve had professional societies and trade guilds for centuries. Charles Dickens sold his novels in subscription format so people subscribed to have access and as he had the chapters done he would deliver them to his subscribers. So this is not a new concept, but what has changed is the ability to build a business model around it that transcends time and space. So Charles Dickens actually had to know the people he was delivering to, had to print it out, had to bring it to them. Today we can deliver it to strangers digitally and we can do it with time lapse. So that has created so many possibilities for organizations to build this ongoing relationship which is what people want.

One example of the difference between a membership economy company and a non-membership economy company is the comparison between Blockbuster and Netflix. So when people, you know, way back when people used to have to go to the corner store to the Blockbuster on a Friday night to see what movies were available to rent, bring them home and it was never the movie that you really wanted. It was whatever happened to be available. And then if you forgot that you had it and you kept it for a few extra days the cost would end up being like triple what you thought it was going to be. And compare that to Netflix where they sent you three DVDs at a time, so three movies that you had on your long list, your queue. You didn’t have to leave your home. You always had three movies at home. And, best of all no late fees. So it’s a very different way of thinking about the model that starts with a forever promise.

A promise of what it is that you really want to achieve. So in the case of Netflix versus Blockbuster, which was what really inspired me, what I wanted was to always have movies, professionally created content delivered in the most efficient way possible because I had little babies, with cost certainty – no late fees. And that’s what Netflix delivered on 15 years ago that pretty much put Blockbuster out of business. And today even though they have streaming, even though they create their own content, even though a lot has changed at Netflix they still deliver everyday on that promise of professional created content delivered with cost certainty in the most efficient way possible.

The time of my life | Ferenc Sarkadi | TEDxBudapestMetropolitanUniversity

Nem valószínű, hogy sok pedagógus van azon a listán, akik 2020 tavaszán az oktatást is érintő változások hallatán ezt gondolták: “végre eljött az én időm.” Pedig Sarkadi Ferenc a március 16-i hétvégén még nem is sejtette, hogy néhány hét múlva a diákjai hamburgerezőt nyitnak, repülőgépet és városokat terveznek – és mintegy mellékesen megmentik az emberiség számára a rántottát. // How many teachers could have felt in March 2020 that those were the days of their lives? Covid stroke in, schools were closed down, and everyone stayed at home in Hungary. Ferenc Sarkadi felt the challenge inspiring from the start. Although, he had no clue that after a few weeks, his pupils will open a burger diner, design aeroplanes and cities …and -as a side-effect- they save poarched eggs for mankind.

Why Jakarta is sinking

The 400-year curse dragging Indonesia’s capital into the sea.

Subscribe to our channel! http://goo.gl/0bsAjO

Like many coastal cities around the world, Jakarta is dealing with sea level rise. But Indonesia’s biggest city also has a unique problem: Because of restricted water access in the city, the majority of its residents have to extract groundwater to survive. And it’s causing the city to sink. Today, Jakarta is the world’s fastest-sinking city.

The problem gets worse every year, but the root of it precedes modern Indonesia by centuries. In the 1600s, when the Dutch landed in Indonesia and built present-day Jakarta, they divided up the city to segregate the population. Eventually, that segregation led to an unequal water piping system that excluded most Indigenous Jakartans, forcing them to find other ways to get water.

To understand how it all ties together, and what’s in store for Jakarta’s future, watch the video above.

Why the ISS Will Be Receiving Experiments With Worms and Grape Juice

Northrop Grumman’s Antares rocket is getting ready for its next resupply mission to the ISS. In addition to critical cargo, the rocket will send up various science experiments to orbit — including worms and grape juice.

Northop Grumman is a longtime favorite as far as NASA resupply missions go. The company has been supplying its Antares rockets since the early 2010’s and will continue to do so until at least 2023. This is mostly because this low cost, two stage, middle class rocket is reliable as heck. And in the last two years installed two newly built RD-181 engines to the first stage of its rocket. Its latest payload capacity is now 8,000 kg, helping to get to Low Earth Orbit with ease.

Antares is rarely ever seen nowadays without the Cygnus spacecraft. This is because it’s another reliable craft that already delivered more than 30,000 kg of critical cargo to the ISS during its first contract missions. And its first launch of this year is NG-15, and the capsule this time around is named after mathematician Katherine Johnson, a black woman who played a critical role during the early days of human space flight. And the mission will be carrying a load more of exciting experiments.

Back in 2018, the Materials International Space Station Experiment – Flight Facility, also known as MISSE-FF, was permanently installed outside of the station. It doesn’t do much, just stands still in different directions for periods of time, BUT is probably one of the most vital ongoing experiments aboard the ISS, and that’s because it tests various materials for the harsh environment of space. We’re talking literally any kind of material from paints to solar cells. MISSE-FF is actually part of a longer MISSE series, starting back in 2001 and to date, it’s tested more than 4,000 kinds of materials. Some of which have helped push our understanding of our solar panels. And now they’re sending up phosphor powders and composites that are used for rapid temperature measurement from 0 degrees celsius to 1,200 degrees celsius.

Katherine Johnson: A Lifetime of STEM
https://www.nasa.gov/audience/foreducators/a-lifetime-of-stem.html
It was this inquisitive nature that made her a valuable resource to the team and the only woman at the time to ever be pulled from the computing pool to work on other programs. Then in 1962, President John F. Kennedy charged the country to send a man to the Moon. Johnson became part of the team, and she began to work on calculating the trajectory for America’s first space trip with Alan Shepherd’s 1961 mission, an early step toward a Moon landing. She went on to do the calculations for the first actual Moon landing in 1969.

Dogs vs Cats: The Diversity Paradox

To make our work paw-sible, join us on Patreon at http://patreon.com/MinuteEarth!
Different dogs look incredibly different – but that doesn’t mean they are necessarily more diverse.

**************
To learn more about this topic, start your googling with these keywords:
phenotypic diversity – the range of different observable traits in a certain organism – for example, size, color, strength, and friendliness.
genetic diversity – the variation in the genetic information within and among individuals of a population or species
artificial selection (or selective breeding) – a process used by humans to develop new organisms with desirable characteristics

Why do we, like, hesitate when we, um, speak? – Lorenzo García-Amaya

Why do we fill pauses in speech with words like “um,” “uh,” and “like”? Dig into the hesitation phenomenon to find out their linguistic significance.

For as long as we’ve had language, some people have tried to control it. And some of the most frequent targets of this communication regulation are the ums, ers, and likes that pepper our conversations. These linguistic fillers occur roughly 2 to 3 times per minute in natural speech. So are ums and uhs just a habit we can’t break? Or is there more to them? Lorenzo García-Amaya investigates.

The chaos and failure that drive creativity towards innovation | Jelle Saldien | TEDxGhent

A story on how education, research and innovation need to be powered by creative thinking (ref Sir Ken Robinson) and the confrontation with failure and perseverance in order to shape a better and more sustainable society. Jelle Saldien is associate Professor at the Department of Industrial Systems Engineering and Product Design of the Faculty of Engineering and Architecture at Ghent University. He received his M.S. degree in Industrial Science ICT at DeNayer Institute (now KULeuven) in 2003 and an additional M.S. degree in Product Development at Artesis (now UAntwerpen) in 2005. In 2009, he received his Ph.D. at the Vrije Universiteit Brussel on the design and development of the social robot Probo. From 2010, he was lecturer in Industrial Design at the Howest University College West Flanders. Since 2013 he is appointed as Professor Industrial Design at Ghent University. From 2014-2017 he was research coordinator of the UGent Industrial Design Center and steering member of Flanders Make VD4. From 2018, he joined the imec-mict-ugent research group and became Principal Investigator in imec. In the meantime, his research has led to ‘Opsoro’; an open platform for social robots, for which he has been honored with the 2019 annual price science communication by the Royal Flemish Academy of Belgium for Science and Arts. In 2017 Jelle was listed as one of the 50 Tech Pioneers in Flanders by news agency De Tijd. In 2019, he started a UGent spinoff named Creative Therapy, that aims to digitize rehabilitation therapy. Furthermore in 2019, Jelle was appointed as UGent board member in the Ministry Of Makers.
Jelle Saldien is author of over 80 technical publications, proceedings, editorials and books. His research looks at the design of interactions between human and technology (Interaction Design). This includes both the physical and digital aspects of future products as perceived by users. Emphasis is placed on new methods for prototyping and the interfaces in Product Design, Human Computer Interaction (HCI) and Human Robot Interaction (HRI), as well as involving (the right) users for product innovation. Currently there is a strong focus on lead-user innovation, information interfaces and open modular system design for intelligent products.

Your Drugs are Average | Cinzia Silvestri | TEDxGhent

We are all different in unique ways, yet most modern treatments ignore individuals’ genetic variations. People from different ethnicities, gender, ages are often limited to take drugs based on a genetic set that is entirely different from their own. What if we could have the perfect medicine for each person? Unfortunately, biologists are missing accurate tools to handle that diversity. In Bi/ond, we create that tool. As a microelectronics engineer, that tool couldn’t be different than what I was used to -a computer chip – where biologists can insert patient tissues. Those tissues are nourished, stimulated, and monitored by the chip, like in the human body. In this environment, it will be possible to test drugs on your cells, making sure they have the desired effect on you. Our technology is part of a sophisticated innovation chain that includes advanced stem-cell technology and big data processing automation technologies. But innovation is just a component. If we want to bring diversity, inclusion, and equity in healthcare, we will need policymakers, researchers, patients, entrepreneurs, investors to join this revolution. Cinzia believes that as every person is unique, our medicine should reflect that as well. She is a resilient and creative entrepreneur who brings real and inclusive innovation to society by applying her passion and knowledge in microelectronics. She is the founder and CEO of Bi/ond, a deep-tech company that empowers diversity in biological studies by engineering microchips. Before going “Bi/ond”, she did her Ph.D. in microelectronics at the prestigious Technical University of Delft. During her academic experience, she realized that her mission is to shorten the distance between academics and industry. Cinzia strongly believes that entrepreneurial role models are needed. She built up a diverse and multidisciplinary team to address the significant challenges in the Organ-on-Chip field. In 2018, she was named one of the 50 most inspiring women in Italy’s technology sector (InspiringFifty – Italy). Thanks to her vision, Bi/ond has been included in the Fund Right Initiative both as a women-lead company and diversity in the team.

General Relativity Explained in 7 Levels of Difficulty

Go to https://curiositystream.com/minutephysics get access to CuriosityStream AND Nebula (where you can watch the extended version of this video), plus you’ll get a 26% discount on an annual subscription.

This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it’s gravity, curved space) through to the concepts of how curved spacetime is represented by psuedo-Riemannian manifolds with Lorentzian signature (that is, special relativity and minkowski space are the local tangent space), how matter and energy are represented by an energy-momentum tensor, and how these two together obey the Einstein Field Equations. The solutions to the Einstein Field Equations (including the schwarzschild metric, kerr metric, freedman-lemaitre-robertson-walker metric, etc) represent gravity around massive objects like the sun, earth, and black holes, but also the history and expansion and future evolution of the cosmos. The universe on a large scale is described by general relativity – on a small scale, quantum mechanics. And where they meet… there’s still work to be done.

Why Robots That Bend Are Better

Robots of the future may be softer, squishier and bendier than robots today. This could make them ideal for space exploration. Check out http://kiwico.com/Veritasium50 for 50% off your first month of any subscription!

On Thursday February 18th, 2021 the NASA Perseverance Rover will land on Mars. It is a wonderful robot, made out of steel and wire — but will future robots look like Perseverance? There is an emerging field of research on “soft robots”, where the machines are flexible. These soft robots have many advantages over traditional robots — they’re safer, lighter, more flexible and can change their shape and size.

NASA is investigating the use of soft robots for space missions. For future visits to Enceladus or Europa, a lander could cut a hole in the ice and then insert a compliant robot through the hole. This robot could then grow and change shape on the other side.

Here’s What Holding Your Breath Does To Your Body

It’s common to see how long you can hold your breath for, but how does your body know when you’re at your breaking point? In this episode of Human, Patrick explains why it comes down to what’s in your blood.
» Subscribe to Seeker! http://bit.ly/subscribeseeker
» Watch more Human! http://bit.ly/HUMANplaylist

The whole point of breathing is so that our tissues can consume oxygen and glucose and turn them into energy, leaving water and carbon dioxide as waste products. This process called cellular respiration is essential to anything that breathes oxygen. And if our tissues don’t get enough oxygen, or experience hypoxia, they can start to die off or see other problems.

There are a bunch of reasons that a tissue might not get enough oxygen — like an iron deficiency might cause anemia, which means that less oxygen will be able to ride on each red blood cell and oxygenate your tissues. Hypoxia can also happen if there’s not enough blood flow to a tissue, like when an artery is too narrow and doesn’t deliver as much blood to its target tissue. Then there’s high altitude where oxygen isn’t as easily available.

High CO2 levels in our blood, or hypercapnia, can cause symptoms like headaches and dizziness, but also more severe symptoms like paranoia, irregular heartbeats, and seizures. Hypercapnia can happen without breath holding too, like if you’re in a submarine or just a stuffy room with the windows closed. Since neither hypoxia or hypercapnia are ideal, our bodies are constantly measuring and reacting to oxygen and carbon dioxide in the blood. That’s where the carotid bodies come in, receptors embedded in the carotid artery in your neck that are triggered by certain chemicals.

Pushing the Limits of Extreme Breath-Holding

“Scientists have long speculated that what feel like physical limits are often merely warning signals generated by the brain’s protective circuitry. In the case of breath-holding, a spate of recent studies offers a glimpse of what it takes to tap into the hidden reserves beyond these boundaries—and what price you might pay for access.”

What’s the secret to holding your breath?
https://www.theguardian.com/science/2014/nov/30/whats-the-secret-to-holding-your-breath
“While our ability to breath-hold may not be all that special, when we compare ourselves with other animals, it’s now proving very useful in one particular area of medicine.”

The Limits of Breath Holding

“It’s logical to think that the brain’s need for oxygen is what limits how long people can hold their breath. Logical, but not the whole story.”

How is diversity being weaponized? | Heather Heying | Big Think

How is diversity being weaponized?
Watch the newest video from Big Think: https://bigth.ink/NewVideo
Join Big Think Edge for exclusive videos: https://bigth.ink/Edge
———————————————————————————-
In efforts to achieve diversity, whether within workplace teams or elsewhere, leaders often focus on variation of identities regarding race, gender, sexual orientation, and physicality.

Evolutionary biologist Heather Heying urges that these efforts be taken a step further to focus on diversity of viewpoints and socioeconomic status — two forms of identity that are less apparent without thoughtful conversation.

Achieving diversity in these ways adds varying life experiences and opinions that enrich office or team culture and provide more innovative solutions.
———————————————————————————-
HEATHER HEYING:

Heather Heying is an evolutionary biologist and former Professor at Evergreen State College. She applies the tool kit of evolutionary theory to problems large and small, some seemingly intractable, some possibly trivial—what to eat, how to teach and parent and be an upstanding citizen, what to avoid, and what to seek.

Heather came to prominence after she and her husband, Bret Weinstein, stood up to supporters of an enforced “Day of Absence” for white staff and teachers at Evergreen State College.

Follow Heather on twitter: @HeatherEHeying and on Medium and through her website, heatherheying.com.
———————————————————————————-
TRANSCRIPT:

HEATHER HEYING: The concept of diversity is honorable and is being weaponized by people who are not, I think, actually interested in true diversity across all demographics. Diversity could be understood merely at a “”we can count this by what you look like and how you identify – your ethnicity, your sex, your sexual orientation, your able-bodiedness,”” these sorts of things. And these are all real ways that humans differ, and the more varied the life histories and the demographics there are in any particular organization, the more likely there are to be unique solutions to problems that emerge because of the different ways that people with diverse backgrounds will approach questions.

However, socioeconomic diversity, which is not often talked about by many of the people who are currently talking about diversity, is in some ways a better predictor of having things like viewpoint diversity and experience with the real world and being able to actually solve problems on the fly, either the physical or the social sort because they’ve had to. Because people who are emerging not from the elite and the upper middle class have actually often had to solve problems in a way that those of us who grew up with greater economic privilege didn’t have to. We may have chosen to put ourselves in these situations, but even so when it’s a choice it’s different.

So diversity is a good, but we are not hearing nearly enough about socioeconomic diversity and we are also not hearing nearly enough about viewpoint diversity, which is hidden, which you can’t wear on your sleeve: I mean you could you could wear a T-shirt that proclaims some things, but the only thing you can proclaim on a T-shirt is an ideology. You cannot proclaim a nuanced worldview except through extended conversation. Most people who have arrived at their beliefs and their values and their worldview through, first, principles as opposed to through accepting something by rote that was handed to them pre-scripted actually don’t fall entirely into a particular ideology. Most of us have views that would sound pretty Democratic and also have views that would sound maybe a bit Republican and some views that are moderate and probably most of us have some extreme views on some topics, and it’s not going to be the same mix for anyone. And we find that through talking with one another.

That diversity, which is diversity at the individual level for people who are not ideologues, who have actually arrived at their positions through careful nuanced intellectual but compassionate thought about the world – that’s the kind of person that you want in a boardroom. And if those people all look the same in terms of their sex or the color of their skin I would say there’s probably some diversity that you’re missing that you could stand to gain. But the idea that you can’t have diversity of life experience and diversity of opinion and diversity of what people actually come to offer in a room of people who appear to look the same by the metric that we are currently being told to use seems far off base to me, that diversity for the countable phenotypic characteristics should not be the highest goal.

How Archaeologists Are Literally Recreating the Past | Experimental Archaeology

This episode is brought to you by the Music for Scientists album! Stream the album on major music services here: https://biglink.to/music-for-scientists. Check out the “For Your Love” music video here: https://youtu.be/YGjjvd34Cvc.

Archaeology might make you think about excavating dinosaur bones or exploring ancient ruins, but we can also learn a lot about the past through experimentation, sometimes with some pretty tasty results!

How to write an email that will always be answered! | Guy Katz | TEDxZurich

Research shows that each of us gets up to 120 emails per day, but we only open 34% of them. By learning just a few basic methods, you can optimize your day and make sure your emails hit the spot, and maybe more importantly: even have fun while writing them.

Let’s spread the recipe of how to write awesome emails – Every character counts 😉 The Swiss would say I am Israeli, Israelis would say I am German; I guess I am a little bit of both, while also blended with a dash of Arab and a pint of American. First serving in the military as an officer, I have worked for governments, startups, non-profits, consulting companies, and giant companies.

Always on the lookout for the right bit of science mixed with practical tips, I now spend my days optimizing the magical recipe for being a father of two amazing boys, a Professor for International Management & Leadership, the owner of a business training company operating worldwide and teaching people how to fly airplanes. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
