Mythbusters’ Adam Savage explains how curiosity can lead to great discoveries

I absolutely love the Mythbusters, and I absolutely love this video – it explains how, with extremely simple equipment, but using logic and a little creativity, we can make fascinating discoveries. He talks about how Eratosthenes calculated the circumference of the Earth 2200 years ago, and how Hippolyte Fizeau measured the speed of light in 1849.
