Making War Make Sense, Mathematically

That is, unless you’re Sean Gourley. The San Francisco-based physicist has applied numbers to conflict zones and several other unlikely places. In 2009, he presented an idea at TED: that the apparent chaos of war contains in it some mathematical logic. Certain patterns, he and his team found, repeated themselves across a number of conflicts, each with its own unhappy mess of factions, problems and economic tensions: Iraq, Colombia, Afghanistan, Senegal, Peru, Indonesia. Armed with his analysis, they could actually “generate an equation that could predict the likelihood of an attack,” as Gourley explains in the accompanying TED Talk. Stephen Petranek: Your kids might live on Mars. Here's how they'll survive. The wars that inspired Game of Thrones - Alex Gendler.

Refresh your understanding of the basic outline with the Encyclopedia Britannica entry, then delve into more details at this dedicated site with a timeline, maps, and descriptions of the major battles.

The wars that inspired Game of Thrones - Alex Gendler

For a closer look at the beginning of the conflict, check out the BBC’s biographies of Richard II and Henry IV. Of course, Shakespeare’s series of plays remains the best-known fictional account of the wars, though not a historically accurate one, and you can even dive into the world of politics and intrigue yourself with a detailed board game. Finally, make sure to read about Richard III’s recent appearance in the news and his proper royal funeral 530 years after his defeat.

Art that blurs the line between paint and photograph. Alexa Meade doesn’t paint on canvas.

Art that blurs the line between paint and photograph

No, as she explains in her talk from TEDGlobal 2013, she paints on something very different — human skin. “If I want to paint your portrait, I’m painting it on you — physically on you. That also means you’re probably going to end up with an ear full of paint because I need to paint your ear on your ear,” says Meade in this extremely fun talk, given at TEDGlobal 2013. “The mask of paint mimics what is directly below it. In this way, I am able to take a three-dimensional scene and make it look like a two-dimensional painting.” Kenneth Lacovara: Hunting for dinosaurs showed me our place in the universe. Mia Birdsong: The story we tell about poverty isn't true.

What really happens to the plastic you throw away - Emma Bryce. If you watched this video, you’re probably interested in how plastics are made, and what impact they have on the environment.

What really happens to the plastic you throw away - Emma Bryce

For starters, you might want to watch this video that shows you how plastic bottles are produced. The American Chemistry Council also has some helpful guidelines on how the material is manufactured, what different types there are, and what role monomers and polymers play in the manufacturing process. (What are monomers and polymers anyway? You can read more about how they’re used in plastics, here.) Moving on from the molecular stuff, plastic also has more visible impacts on the earth. Schrödinger's cat: A thought experiment in quantum mechanics - Chad Orzel. Here’s are more TED-Ed Lessons by the same educator: Particles and waves: The central mystery of quantum mechanics and What is the Heisenberg Uncertainty Principle?

Schrödinger's cat: A thought experiment in quantum mechanics - Chad Orzel

Schrödinger’s Cat is a very fertile subject for discussion, and has also been discussed in this lesson from Josh Samani. Here’s more about the thought experiment described briefly by Minute Physics. Go to the Sixty Symbols video and learn much more detail about Schrodinger’s Cat. For a humorous look at this cat experiment, venture to this site for a simulation. Tabetha Boyajian: The most mysterious star in the universe. Elizabeth Gilbert: A new way to think about creativity. A new Tree of Life reminds us to question what we know. Since Darwin’s day, scientists have worked to map all of life on a single tree to show how all forms of life on Earth evolved and are related.

A new Tree of Life reminds us to question what we know

The DNA sequencing revolution has allowed us to fill in more of the blanks than ever before, greatly accelerating research into biodiversity and Earth’s ecosystems and constantly changing our understanding of life. Last week, our perspective shifted dramatically when researchers unveiled a newly updated Tree of Life showing a whole branch of heretofore-unknown microbes that appear to dominate Earth’s biodiversity. We asked biodiversity mathematician and TED Fellow Hélène Morlon – who uses computer models and the Tree of Life to better understand the forces that shape evolution – to explain why the new phylogenetic tree is changing the way we view life on Earth. Tom Uglow: An Internet without screens might look like this. Clay Shirky: How cognitive surplus will change the world.

Gallery: Why the stories of Ellis Island matter today

The women wear headscarves, the men thick coats, the children the travel-weary expressions of those who have come a very long way. Oren Yakobovich: Hidden cameras that film injustice in the world’s most dangerous places. Pourquoi j’ai créé une école où les enfants font ce qu’ils veulent. What should the future of capitalism look like? Greece’s former finance minister Yanis Varoufakis calls himself a libertarian Marxist Keynesian — or “completely confused,” as he jokes.

What should the future of capitalism look like?

So it was hard to predict how he would react to Zambian economist Dambisa Moyo, a more traditional proponent of free markets. The two economists spoke with TED’s European director Bruno Giussani ahead of December’s TEDGlobal conference in Geneva, where they argued that during these uncertain economic times we should question ideologies, discard certitudes and adapt to a messy, new economic reality. They share their views on how to revive the global economy (the text has been edited for length and clarity). What’s wrong with the world economy today? Dambisa Moyo: We, the international community, very successfully convinced a whole swathe of emerging market countries that they should be more democratic and they should be more market friendly.

Should politicians meddle with the free market? Youngest solo sailor, around the world at 16: Laura Dekker at TEDxYouth@Auckland. Taryn Simon: Photographs of secret sites. What doctors don’t learn about death and dying. I learned about a lot of things in medical school, but mortality wasn’t one of them.

What doctors don’t learn about death and dying

I was given a dry, leathery corpse to dissect in my first term — but that was solely a way to learn about human anatomy. Our textbooks had almost nothing on aging or frailty or dying. How the process unfolds, how people experience the end of their lives and how it affects those around them? That all seemed beside the point. Kevin Allocca: Why videos go viral. Que se passera-t-il quand nos ordinateurs deviendront plus intelligents que nous ?: What happens when our computers get smarter than we are? The mathematical secrets of Pascal’s triangle - Wajdi Mohamed Ratemi. Math is really fun!

Marina Abramović: An art made of trust, vulnerability and connection. BLACK: My journey to yo-yo mastery. Tristram Stuart: The global food waste scandal. Why we need to slow down our lives. The idea of going nowhere is as universal as the law of gravity; that’s why wise souls from every tradition have spoken of it. “All the unhappiness of men,” the seventeenth-century French mathematician and philosopher Blaise Pascal famously noted, “arises from one simple fact: that they cannot sit quietly in their chamber.” After Admiral Richard E. Byrd spent nearly five months alone in a shack in the Antarctic, in temperatures that sank to 70 degrees below zero, he emerged convinced that “Half the confusion in the world comes from not knowing how little we need.”

Or, as they sometimes say around Kyoto, “Don’t just do something. Sit there.” Yet the days of Pascal and even Admiral Byrd seem positively tranquil by today’s standards. And the more facts come streaming in on us, the less time we have to process any one of them. Fabian Oefner: Psychedelic science. Andres Lozano: Parkinson's, depression and the switch that might turn them off. Miguel Nicolelis: A monkey that controls a robot with its thoughts. No, really.

Why are we being such idiots about climate change? When I started covering climate change more than thirty years ago, the underlying science was already clear. Heat from the sun warms the Earth. Gases like carbon dioxide in the atmosphere then act like a snuggly blanket or greenhouse to trap much of that warmth, keeping much of the heat from radiating back out to space. For humans, this greenhouse effect is a vital — and fortuitous — physical phenomenon. A new way to combat food waste. Cucumbers wasted per week at The Netherland’s largest cucumber farm. (Credit: Fiona Jongejans) It is normal — and sometimes even regulated — for absolutely edible and healthy food products to be discarded merely due to cosmetic reasons, says industrial designer Fiona Jongejans at TEDxMaastricht. In the Netherlands, where Jongejans lives, fruits and vegetables are placed into different classes, with a cucumber required to be “practically straight … [with the] maximum height of the inner arc [being] 10 mm per 10 cm of length” to be considered “class I.”

Scott Dinsmore: How to find work you love. James B. Glattfelder: Who controls the world? How to give a persuasive presentations: A Q&A with Nancy Duarte. Stepping onto the TED or TEDx stage — or speaking in front of any group of people, for that matter — is truly nerve-wracking. Will you remember everything you wanted to say, or get so discombobulated that you skip over major points? Will the audience be receptive to your ideas, or will you notice a guy in row three nodding off to sleep? Presentation expert Nancy Duarte, who gave the TED Talk “The secret structure of great talks,” has built her career helping people express their ideas in presentations. Markham Nolan: How to separate fact and fiction online. Scott Dinsmore: How to find work you love. BJ Miller: What really matters at the end of life.

The importance of self-care. Want to be happy? SLOW DOWN. In 1972, Matthieu Ricard had a promising career in biochemistry, trying to figure out the secrets of E. coli bacteria. A chance encounter with Buddhism led to an about turn, and Ricard has spent the past 40+ years living in the Himalayas, studying mindfulness and happiness. In this free-wheeling discussion at TED Global in October 2014, Ricard talked with journalist and writer Pico Iyer about some of the things they’ve learned over the years, not least the importance of being conscious about mental health and how to spend time meaningfully. An edited version of the conversation, moderated by TED Radio Hour host Guy Raz, follows.

Quand le cheval dévoile les limites de l'homme: Jean Loup PEGUIN at TEDxRennes. Talks on how to love work again. How to watch a presidential debate (or win it): Tips from Amy Cuddy. Amy Cuddy’s TED Talk, Your body language shapes who you are, has millions of views for a reason — everyone who watched it understood a little bit more about themselves. But the flip side of her research is equally fascinating — how we can understand others through the body language they, consciously or unconsciously, choose to use. Back during the last U.S. presidential election in 2012, our writer Ben Lillie sat down to ask Dr.

How does my brain work? Debra Jarvis: Yes, I survived cancer. But that doesn't define me. Gary Haugen: The hidden reason for poverty the world needs to address now. Gallery: How networks help us understand the world. As designer Manuel Lima points out in his TED Talk, A visual history of human knowledge, the network has become a powerful way to visualize much of what is going on in the world around us.

“Networks really embody notions of decentralization, of interconnectedness, of interdependence,” says Lima. “This way of thinking is critical for us to solve many of the complex problems we are facing nowadays, from decoding the human brain to understanding the vast universe out there.” Why humans run the world. 70,000 years ago humans were insignificant animals. The dark side of data. Now playing. The mathematical secrets of Pascal’s triangle - Wajdi Mohamed Ratemi.
