Dig into the era of China’s Cultural Revolution, and how communist leader Mao Zedong used mangoes as a propaganda tool.--In August 1968, factory workers overheard news of a mandatory meeting. Whispered rumors described shipments of a gift from the country’s Communist leader, Chairman Mao Zedong. And sure enough, managers soon distributed a gift to every factory worker– a glass box encasing a golden wax replica of a mango. What was the meaning behind this unusual offering?

Five great revolutions have shaped political culture over the past 50 years, says theorist Ivan Krastev. He shows how each step forward -- from the cultural revolution of the '60s to recent revelations in the field of neuroscience -- has also helped erode trust in the tools of democracy. As he says, "What went right is also what went wrong." Can democracy survive? Talk by Ivan Krastev.

Explore how scientists define adulthood, and find out if there’s a specific age at which we reach maturity. --Most countries recognize 18 as the start of adulthood by granting various freedoms and privileges. Yet there’s no exact age or moment in development that we can point to as having reached full maturity. If there’s no consensus on exactly when we reach maturity, when do we actually become adults? Shannon Odell shares how scientists define adulthood using stages of brain development.Lesson by Shannon Odell, directed by Biljana Labović.This video made possible in collaboration with Bezos Family FoundationLearn more about how TED-Ed partnerships work: https://bit.ly/TEDEdPartnersSupport Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/when-are-you-actually-an-adult-shannon-odellDig deeper with additional resources: https://ed.ted.com/lessons/when-are-you-actually-an-adult-shannon-odell#digdeeper----------------------------------------------Thank you so much to our patrons for your support!

Dig into the psychology of why rejection causes us pain, and explore strategies to cope with this common experience.--Rejection hurts. It’s incredibly painful to feel like you’re not wanted — and we do mean painful. Researchers found that we relate rejection to being “hurt,” using terms like “crushed” or “broken-hearted.” So, why does rejection trigger such a strong response, and is there any way to cope with this unique kind of pain? Explore common strategies to help you process this emotional experience.Directed by Caitlin McCarthy.This video made possible in collaboration with Character LabLearn more about how TED-Ed partnerships work: https://bit.ly/TEDEdPartnersA special thanks to Mark Leary who provided information and insights for the development of this video.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/how-to-deal-with-rejectionDig deeper with additional resources: https://ed.ted.com/lessons/how-to-deal-with-rejection#digdeeperAnimator's website: https://c8l.in----------------------------------------------Thank you so much to our patrons for your support!
