I would like to introduce you to Ted Talks. Here is just one of thousands of "less than 20 minute" talks by the best and brightest in the world. I chose Isabel Allende, and her talk on passion, because she is from Chile, and so entertaining.
These "talks" span brains, and books, and bees, and hope and technology and bio-engineering, and medicine and evolution, love, disability, diversity and ideas and themes that will cause you to think and wonder differently about the world.
