Chia-Ching, your recommendation for November 9, 2019 is...

Baratunde Thurston explores the phenomenon of white Americans calling the police on black Americans who have committed the crimes of ... eating, walking or generally "living while black." In this profound, thought-provoking and often hilarious talk, he reveals the power of language to change stories of trauma into stories of healing -- while challenging us all to level up.

The phrase, "Laugh to keep from crying" usually means we do the first instead to forestall the second. Baratunde actually uses laughter to try to prevent the tragic outcomes that make us cry. Making anti-racism funny takes a special kind of brilliance. And making comedy do the work of anti-racism…Baratunde is a special talent.

After billions of years of monotony, the universe is waking up

15:10 minutes · Filmed Apr 2019 · Posted Oct 2019 · TED2019

Theoretical physicist David Deutsch delivers a mind-bending meditation on the "great monotony" -- the idea that nothing novel has appeared in the universe for billions of years -- and shows how humanity's capacity to create explanatory knowledge could be the thing that bucks this trend. "Humans are not playthings of cosmic forces," he says. "We are users of cosmic forces."

This week's new TED Talks

How we can eliminate child sexual abuse material from the internet
Social entrepreneur Julie Cordua works on a problem that isn't easy to talk about: the sexual abuse of children in images and videos on the internet. At Thorn, she's building technology to connect the dots between the tech industry, law enforcement and government -- so we can swiftly end the viral distribution of abuse material and rescue children faster. (This ambitious plan is part of the Audacious Project, TED's initiative to inspire and fund global change.)

An app that helps incarcerated people stay connected to their families
Over his eight-year prison sentence, Marcus Bullock was sustained by his mother's love -- and by the daily letters and photos she sent of life on the outside. Years later, as an entrepreneur, Bullock asked himself: How can I make it easier for all families to stay connected during incarceration? Enter FlikShop: an app he developed that lets families send quick postcards to loved ones in prison and help keep open a critical line of support.

The psychological impact of child separation at the US-Mexico border
How does psychological trauma affect children's developing brains? In this powerful talk, social worker Luis H. Zayas discusses his work with refugees and asylum-seeking families at the US-Mexico border. What emerges is a stunning analysis of the long-term impact of the US's controversial detention and child separation policies -- and practical steps for how the country can do better.

A circular economy for salt that keeps rivers clean
During the winter of 2018-2019, one million tons of salt were applied to icy roads in the state of Pennsylvania alone. The salt from industrial uses like this often ends up in freshwater rivers, making their water undrinkable and contributing to a growing global crisis. How can we better protect these precious natural resources? Physical organic chemist Tina Arrowood shares a three-step plan to keep salt out of rivers -- and create a circular salt economy that turns industrial byproducts into valuable resources.

How a handful of fishing villages sparked a marine conservation revolution
We need a radically new approach to ocean conservation, says marine biologist Alasdair Harris. In a visionary talk, he lays out a surprising solution to the problem of overfishing that could both revive marine life and rebuild local fisheries -- all by taking less from the ocean.

A love story for the coral reef crisis
Over the course of dozens of scuba diving trips, marine biologist Ayana Elizabeth Johnson fell in love -- with a fish. In this ode to parrotfish, she shares five reasons why these creatures are simply amazing (from their ability to poop white sand to make colorful "wardrobe changes") and shows why they need our protection from the destruction of coral reefs.
