    How does laser eye surgery work? - Dan Reinstein

    Explore the eye-opening science of LASIK: corrective laser eye surgery that focuses on reshaping the cornea to fix blurry vision. -- In 1948, Spanish ophthalmologist Jose Ignacio Barraquer Moner was fed up with glasses. He wanted a solution for blurry vision that fixed the eye itself, without relying on external aids. The surgery he eventually devised was called “keratomileusis,” and his technique focused on reshaping the cornea— what we now know as LASIK. So how does laser eye surgery actually work?

    How do our brains process speech? - Gareth Gaskell

    Learn how to identify, develop, and share your best ideas with TED Masterclass: http://bit.ly/tedmasterclass -- The average 20-year-old knows between 27,000 and 52,000 different words. Spoken out loud, most of these words last less than a second. With every word, the brain has a quick decision to make: which of those thousands of options matches the signal?
