👁Let's launch a satellite to track a threatening greenhouse gas
‌
🗣Subtitle: Farsi | English | Turkish

👣When we talk about greenhouse gases, carbon dioxide gets the most attention -- but methane, which often escapes unseen from pipes and wells, has a far greater immediate impact on global warming. Environmentalist Fred Krupp has an idea to fix the problem: launch a satellite that tracks global methane emissions, and openly share the data it collects with the public. Learn more about how simple fixes to cut down on this invisible pollutant can help us put the brakes on climate change. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)

👁Hopeful lessons from the battle to save rainforests
‌
🗣Subtitle: Farsi | English | Turkish

👣\"Save the rainforest\" is an environmental slogan as old as time — but Tasso Azevedo catches us up on how the fight is actually going these days.

👁How high can you count on your fingers? (Spoiler: much higher than 10) - James Tanton
‌
🗣Subtitle: Farsi | English | Turkish
👣How high can you count on your fingers? It seems like a question with an obvious answer. After all, most of us have ten fingers -- or to be more precise, eight fingers and two thumbs. This gives us a total of ten digits on our two hands, which we use to count to ten. But is that really as high as we can go? James Tanton investigates.

👁A new way to fund health care for the most vulnerable
‌
🗣Subtitle: Farsi | English

👣In 2011, eye surgeon and TED Fellow Andrew Bastawrous developed a smartphone app that brings quality eye care to remote communities, helping people avoid losing their sight to curable or preventable conditions. Along the way, he noticed a problem: strict funding regulations meant that he could only operate on people with specific diseases, leaving many others without resources for treatment. In this passionate talk, Bastawrous calls for a new health care funding model that's flexible and ambitious -- to deliver better health to everyone, whatever their needs are.

👁Should we be looking for life elsewhere in the universe? - Aomawa Shields
‌
🗣Subtitle: Farsi | English | Turkish
👣As the number of “potentially habitable” planets that astronomers find continues to rise, we seem ever closer to answering the question, “Are we alone in the universe?” But should we be looking for life elsewhere? If we were to find life in one of these worlds, should we try to contact any beings who may live there? Is that wise? Aomawa Shields navigates the murky waters of pursuing curiosity.
