TEDTalks Technologie

Scheinbar sinnlose wissenschaftliche Forschung kann zu außergewöhnlichen Entdeckungen führen, sagt Physikerin Suzie Sheehy. Mit ihrem Vortrag und einigen technischen Experimenten demonstriert sie uns, wie viele unserer modernen Technologien auf jahrhundertealte Experimente zurückgehen, die nur auf Neugier basierten. Damit hält sie ein Plädoyer dafür, dass wir mehr investieren müssen, um die Welt besser zu verstehen.

By 2050, an estimated 10 billion people will live on earth. How are we going to provide everybody with basic needs while also avoiding the worst impacts of climate change? In a talk packed with wit and wisdom, science journalist Charles C. Mann breaks down the proposed solutions and finds that the answers fall into two camps -- wizards and prophets -- while offering his own take on the best path to survival.

Wir sind weit davon entfernt, empfindungsfähige Roboter zu entwickeln. Jedoch haben wir schon Gefühle für sie, sagt Roboterethikerin Kate Darling, und ein solcher Instinkt kann Konsequenzen haben. Lernen Sie mehr darüber, wie wir biologisch darauf programmiert sind, Absicht und Leben auf Maschinen zu projizieren -- und wie es uns helfen könnte uns selbst besser zu verstehen.

In a talk that's part history lesson, part love letter to graphics, information designer Tommy McCall traces the centuries-long evolution of charts and diagrams -- and shows how complex data can be sculpted into beautiful shapes. "Graphics that help us think faster, or see a book's worth of information on a single page, are the key to unlocking new discoveries," McCall says.

Unsere Fingerabdrücke sind das, was uns einzigartig macht -- aber sie sind auch Tor zu einer Welt voller in Molekülen versteckter Informationen, die unsere Handlungen, Lebensstile und Gewohnheiten offenbaren. In dieser fesselnden Rede zeigt Chemikerin Simona Francese, wie sie diese mikroskopisch kleinen Spuren mittels Massenspektografie untersucht, eine Technologie, die Fingerabdrücke in vorher undenkbarem Detail analysiert und demonstriert, wie diese supermoderne, forensische Wissenschaft der Polizei dabei helfen kann, Kriminelle zu fangen.

If you ever struggle to make decisions, here's a talk for you. Cognitive scientist Tom Griffiths shows how we can apply the logic of computers to untangle tricky human problems, sharing three practical strategies for making better decisions -- on everything from finding a home to choosing which restaurant to go to tonight.

Meet AIVA, an artificial intelligence that has been trained in the art of music composition by reading more than 30,000 of history's greatest scores. In a mesmerizing talk and demo, Pierre Barreau plays compositions created by AIVA and shares his dream: to create original live soundtracks based on our moods and personalities.

In a series of mind-bending demos, inventor Mary Lou Jepsen shows how we can use red light to see and potentially stimulate what's inside our bodies and brains. Taking us to the edge of optical physics, Jepsen unveils new technologies that utilize light and sound to track tumors, measure neural activity and could possibly replace the MRI machine with a cheaper, more efficient and wearable system.

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 and TED Fellow 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.

Do you think you're good at spotting fake videos, where famous people say things they've never said in real life? See how they're made in this astonishing talk and tech demo. Computer scientist Supasorn Suwajanakorn shows how, as a grad student, he used AI and 3D modeling to create photorealistic fake videos of people synced to audio. Learn more about both the ethical implications and the creative possibilities of this tech -- and the steps being taken to fight against its misuse.
