Getting back to Franklin, he pioneered many aspects of electricity. In one of his less successful experiments, he almost killed himself with electricity from a battery, in 1750. It sounds like a cold fusion experiment gone bad. He was trying to electrocute a turkey. He wrote: "I have lately made

What Ben said about finding the truth in nature is valid, but finding what will work in Engineering is a different issue. A good engineer will imagine a billion ways in which an invention will fail so that invention is built to avoid all those failure modes. The disciples of Cassandra make the
