Below are three interesting and stimulating podcasts from past TED conferences.

• Sir Ken Robinson makes an entertaining (and profoundly moving) case for creating an education system that nurtures creativity, rather than undermining it. With ample anecdotes and witty asides, Robinson points out the many ways our schools fail to recognize -- much less cultivate -- the talents of many brilliant people. "We are educating people out of their creativity," Robinson says. The universality of his message is evidenced by its rampant popularity online. A typical review: "If you have not yet seen Sir Ken Robinson's TED talk, please stop whatever you're doing and watch it now."

• Neuroanatomist Jill Bolte Taylor had an opportunity few brain scientists would wish for: One morning, she realized she was having a massive stroke. As it happened -- as she felt her brain functions slip away one by one, speech, movement, understanding -- she studied and remembered every moment. This is a powerful story about how our brains define us and connect us to the world and to one another.

• In this soaring demonstration, deaf percussionist Evelyn Glennie leads the audience through an exploration of music not as notes on a page, but as an expression of the human experience. Playing with sensitivity and nuance informed by a soul-deep understanding of and connection to music, she talks about a music that is more than sound waves perceived by the human ear. She illustrates a richer picture that begins with listening to yourself, and includes emotion and intent as well as the complex role of physical spaces -- instrument, concert hall and even the bones and body cavities of musician and listener alike.
