things outside of physics. According to at least one analyst, the Cold War was WWIII and the War on Terrorism is WWIV. If he's right, and he makes some pretty good arguments to support his case, then once again Einstein was wrong (as he was when he dismissed the Uncertainty Principle with the statement, "God doesn't play dice with the universe.")

Einstein was one of the world's great intellects on physics, but like everyone else, he had his limitations when he ventured outside his area of expertise. History provides many examples where prominent scientists and "experts" claimed something was impossible only to be soon proven wrong. This is especially true when they talk about things outside of their domain of expertise.
