Thanks to both of you for the praise. You might also be interested in "The Secret Life of Machines". [link] and [this video] . Philip Morrison (from Ring of Truth) is perhaps best known for his powers-of-10 movie. [link] . He was also a columnist for Scientific American. The only column I remember is when he decided to make bread from scratch. Really from scratch. They grew wheat in a small plot of land near his home in Cambridge, Mass. He's part of the generation that developed the first atomic bomb. He carried the first core to the Trinity test site in the back seat of his car, and helped load the weapons on the planes that went to Japan.
