A brilliant article with many lessons. Some of the comments from last time it was submitted are interesting: http://news.ycombinator.com/item?id=589608 http://news.ycombinator.com/item?id=589608 Another story about Einstein is told by a small girl who sees an apparently crazy man standing in a public square in front of a fountain waving his hands in front of his face. He turned to her and said: "See! If you wave them at the right speed and look through your fingers, you can make the droplets stand still!" That's the story that has always stuck with me, the delight in simple, elementary techniques to reveal things that otherwise can't be seen. The story of progressing from the simple through phases to greater and greater complexity is also of value. Oldie, goodie, and definitely worth remembering.
