👁Mary's Room: A philosophical thought experiment - Eleanor Nelsen
🗣Subtitle: Farsi | English | Turkish
👣Imagine a neuroscientist who has only ever seen black and white things, but she is an expert in color vision and knows everything about its physics and biology. If, one day, she sees color, does she learn anything new? Is there anything about perceiving color that wasn’t captured in her knowledge? Eleanor Nelsen explains what this thought experiment can teach us about experience.

👁Chimps have feelings and thoughts. They should also have rights
🗣Subtitle: Farsi | English | Turkish
👣Chimpanzees are people too, you know. Ok, not exactly. But lawyer Steven Wise has spent the last 30 years working to change these animals' status from \"things\" to \"persons.\" It's not a matter of legal semantics; as he describes in this fascinating talk, recognizing that animals like chimps have extraordinary cognitive capabilities and rethinking the way we treat them -- legally -- is no less than a moral duty.

👁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.)

👁Moral behavior in animals
🗣Subtitle: Farsi | English | Turkish
👣What happens when two monkeys are paid unequally? Fairness, reciprocity, empathy, cooperation -- caring about the well-being of others seems like a very human trait.

👁What causes antibiotic resistance? - Kevin Wu
🗣Subtitle: Farsi | English

👁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. Spurred by the jaw-dropping losses of the 1990s, new laws (and transparent data) are helping slow the rate of deforestation in Brazil. Is it enough? Not yet. He has five ideas about what we should do next. And he asks if the lessons learned in Brazil could be applied to an even bigger problem: global climate change.

👁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.
