TED is a nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. TEDTalks began as a simple attempt to share what happens at TED with the world. Under the moniker "ideas worth spreading," talks were released online. They rapidly attracted a global audience in the millions. Indeed, the reaction was so enthusiastic that the entire TED website has been reengineered around TEDTalks, with the goal of giving everyone on-demand access to the world's most inspiring voices.

#9 - Steven Pinker: Is the world getting better or worse? A look at the numbers

Season 2018 - Episode 135 - Aired 4/30/2018

Was 2017 really the "worst year ever," as some would have us believe? In his analysis of recent data on homicide, war, poverty, pollution and more, psychologist Steven Pinker finds that we're doing better now in every one of them when compared with 30 years ago. But progress isn't inevitable, and it doesn't mean everything gets better for everyone all the time, Pinker says. Instead, progress is problem-solving, and we should look at things like climate change and nuclear war as problems to be solved, not apocalypses in waiting. "We will never have a perfect world, and it would be dangerous to seek one," he says. "But there's no limit to the betterments we can attain if we continue to apply knowledge to enhance human flourishing."

In this joyful, heartfelt talk featuring demos of her wonderfully wacky creations, Simone Giertz shares her craft: making useless robots. Her inventions — designed to chop vegetables, cut hair, apply lipstick and more — rarely (if ever) succeed, and that's the point. "The true beauty of making useless things [is] this acknowledgment that you don't always know what the best answer is," Giertz says. "It turns off that voice in your head that tells you that you know exactly how the world works. Maybe a toothbrush helmet isn't the answer, but at least you're asking the question."

#18 - Pratik Shah: How AI is making it easier to diagnose disease

Season 2018 - Episode 225 - Aired 7/24/2018

Today's AI algorithms require tens of thousands of expensive medical images to detect a patient's disease. What if we could drastically reduce the amount of data needed to train an AI, making diagnoses low-cost and more effective? TED Fellow Pratik Shah is working on a clever system to do just that. Using an unorthodox AI approach, Shah has developed a technology that requires as few as 50 images to develop a working algorithm — and can even use photos taken on doctors' cell phones to provide a diagnosis. Learn more about how this new way to analyze medical information could lead to earlier detection of life-threatening illnesses and bring AI-assisted diagnosis to more health care settings worldwide.
