👁The mind behind Linux
‌
🗣Subtitle: Farsi | English | Turkish

👣Linus Torvalds transformed technology twice -- first with the Linux kernel, which helps power the Internet, and again with Git, the source code management system used by developers worldwide. In a rare interview with TED Curator Chris Anderson, Torvalds discusses with remarkable openness the personality traits that prompted his unique philosophy of work, engineering and life. \"I am not a visionary, I'm an engineer,\" Torvalds says. \"I'm perfectly happy with all the people who are walking around and just staring at the clouds ... but I'm looking at the ground, and I want to fix the pothole that's right in front of me before I fall in.\"

‌

👁How isolation fuels opioid addiction
‌
🗣Subtitle: Farsi | English

👁The most important thing you can do to fight climate change: talk about it
‌
🗣Subtitle: Farsi | English

👣How do you talk to someone who doesn't believe in climate change? Not by rehashing the same data and facts we've been discussing for years, says climate scientist Katharine Hayhoe. In this inspiring, pragmatic talk, Hayhoe shows how the key to having a real discussion is to connect over shared values like family, community and religion -- and to prompt people to realize that they already care about a changing climate. \"We can't give in to despair,\" she says. \"We have to go out and look for the hope we need to inspire us to act -- and that hope begins with a conversation, today.\"

👁A new way to monitor vital signs (that can see through walls)
‌
🗣Subtitle: Farsi | English | Turkish

👣At MIT, Dina Katabi and her team are working on a bold new way to monitor patients' vital signs in a hospital (or even at home), without wearables or bulky, beeping devices. Bonus: it can see through walls. In a mind-blowing talk and demo, Katabi previews a system that captures the reflections of signals like Wi-Fi as they bounce off people, creating a reliable record of vitals for healthcare workers and patients. And in a brief Q&A with TED curator Helen Walters, Katabi discusses safeguards being put in place to prevent people from using this tech to monitor somebody without their consent.
