What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower — and do it in a way that’s more efficient, secure and widespread.
In 2011, journalist Bruno Torturra covered a protest in São Paulo which turned ugly. His experience of being teargassed had a profound effect on the way he thought about his work, and he quit his job to focus on broadcasting raw, unedited experiences online. In this fascinating talk, he shares some of the ways in which he’s experimented with live streaming on the web, and how in the process he has helped to create a very modern media network.
How often does technology interrupt us from what we really mean to be doing? At work and at play, we spend a startling amount of time distracted by pings and pop-ups — instead of helping us spend our time well, it often feels like our tech is stealing it away from us. Design thinker Tristan Harris offers thoughtful new ideas for technology that creates more meaningful interaction. He asks: “What does the future of technology look like when you’re designing for the deepest human values?”
Rivers are one of nature’s most powerful forces — they bulldoze mountains and carve up the earth, and their courses are constantly moving. Understanding how they form and how they’ll change is important for those that call their banks and deltas home. In this visual-packed talk, geoscientist Liz Hajek shows us how rocks deposited by ancient rivers can be used as a time machine to study the history of the earth, so we can figure out how to more sustainably live on it today.
When two people are trying to make a deal — whether they’re competing or cooperating — what’s really going on inside their brains? Behavioural economist Colin Camerer shows research that reveals how badly we predict what others are thinking. Bonus: He presents an unexpected study that shows chimpanzees might just be better at it.
