David Damberger’s work with Engineers Without Borders has taken him from communities in India to Southern Africa to help build infrastructure -- and learn.

Yves Béhar and Forrest North unveil Mission One, a sleek, powerful electric motorcycle. They share slides from distant (yet similar) childhoods that show how collaboration kick-started their friendship -- and shared dreams.

What could you do with the world's smallest 3D printer? Klaus Stadlmann demos his tiny, affordable printer that could someday make customized hearing aids -- or sculptures smaller than a human hair.

Concrete is all around us: we use it to build our roads, buildings, bridges and much more. Yet over the last 2,000 years, the art of mixing cement and using it to bind concrete hasn't changed very much -- and it remains one of the world's biggest emitters of carbon. Entrepreneur Tom Schuler previews an innovative way to create concrete, potentia...

Surgeons are required every day to puncture human skin before procedures — with the risk of damaging what's on the other side. In a fascinating talk, find out how mechanical engineer Nikolai Begg is using physics to update an important medical device, called the trocar, and improve one of the most dangerous moments in many common surgeries.

Tribology: it's a funny-sounding word you might not have heard before, but it could change how you see and interact with the physical world, says mechanical engineer Jennifer Vail. Offering lessons from tribology -- the study of friction and wear -- Vail describes the surprisingly varied ways it impacts everyday life and how it could help us mak...

A flying car -- it's an iconic image of the future. But after 100 years of flight and automotive engineering, no one has really cracked the problem. Pilot Anna Mracek Dietrich and her team flipped the question, asking: Why not build a plane that you can drive?

Luck is rarely a lightning strike, isolated and dramatic -- it's much more like the wind, blowing constantly. Catching more of it is easy but not obvious. In this insightful talk, Stanford engineering school professor Tina Seelig shares three unexpected ways to increase your luck -- and your ability to see and seize opportunities.

When architect Antón García-Abril moved to Boston, he quickly discovered that his budget wouldn't stretch to the sort of airy, modern home he had in his native Madrid. His solution: to ship a prefabricated house from Madrid to Boston. Using video documentation to illustrate his point, García-Abril explains how his home-in-a-box could represent t...

Your mobile phone, computer and game console have a bloody past — tied to tantalum mining, which funds the war in the Democratic Republic of the Congo. Drawing on his personal story, activist and refugee Bandi Mbubi gives a stirring call to action.

It may seem that big problems require big solutions, but ad man Rory Sutherland says many flashy, expensive fixes are just obscuring better, simpler answers. To illustrate, he uses behavioral economics and hilarious examples.

These exciting innovations and breakthroughs demonstrate what's possible when humans draw inspiration from some of nature’s best work.

Always wanted to do something more with your free time? Let these talks inspire you to take up anything from a classic hobby, to something a little less conventional.

Inspiring talks from women who have pushed the boundaries in their field and are paving the way for the next generation of girls to earn their place in traditionally male-dominated professions.

Chris Domas is a cybersecurity researcher, operating on what's become a new front of war, "cyber." In this engaging talk, he shows how researchers use pattern recognition and reverse engineering (and pull a few all-nighters) to understand a chunk of binary code whose purpose and contents they don't know.

In 1991, Linus Torvalds shared the Linux kernel with a few computer hobbyists. The operating system they built reshaped the software industry.

To futureproof your job against robots and AI, you should learn how to code, brush up on your math skills and crack open an engineering textbook, right? Wrong. In this surprisingly comforting talk, tech journalist Kevin Roose makes the case that rather than trying to compete with the machines, we should instead focus on what makes us uniquely hu...

With technical advancement comes great ethical responsibility. In these talks, amazing, life-altering feats of science make us ask: How could we mess this up?

In 1990, the Italian government enlisted top engineers to stabilize Pisa's famous Leaning Tower. There'd been many attempts during its 800 year history, but computer models revealed the urgency of their situation. The tower would topple if it reached an angle of 5.44 degrees— and it was currently leaning at 5.5. What gives the tower its infamous...

Renowned paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking living descendants of the dinosaur (chickens) and genetically engineering them to reactivate ancestral traits — ...

The COVID-19 pandemic has upended how we think about the workplace. TED curator Chee Pearlman and James Ludwig, vice president of global design and product engineering at Steelcase, discuss how we can use this time as an opportunity to reflect on what matters most – and make the office of the future even better in the process. (Recorded June 16,...

Computer science began in the '30s ... the 1830s. John Graham-Cumming tells the story of Charles Babbage's mechanical, steam-powered "analytical engine" and how Ada Lovelace, mathematician and daughter of Lord Byron, saw beyond its simple computational abilities to imagine the future of computers.

For the dawn of a new decade, adventurer Bertrand Piccard offers us a challenge: Find motivation in what seems impossible. He shares his own plans to do what many say can't be done -- to fly around the world, day and night, in a solar-powered aircraft.

Joe Lassiter focuses on one of the world’s most pressing problems: developing clean, secure and carbon-neutral supplies of reliable, low-cost energy all around the world.

Maurice Conti explores new partnerships between technology, nature and humanity.

Lisa Nip's work focuses on how we can use synthetic biology to allow humanity to explore space

Linus Torvalds transformed technology twice -- first with the Linux kernel, which helps power the Internet, and again with Git, the source code management system used by developers worldwide. In a rare interview with TED Curator Chris Anderson, Torvalds discusses with remarkable openness the personality traits that prompted his unique philosophy...

That crazy, sci-fi future we all imagine? It’s here.

Forests don't have to be far-flung nature reserves, isolated from human life. Instead, we can grow them right where we are -- even in cities. Eco-entrepreneur and TED Fellow Shubhendu Sharma grows ultra-dense, biodiverse mini-forests of native species in urban areas by engineering soil, microbes and biomass to kickstart natural growth processes....
