This episode asks why mankind is gold crazy, and discovers there's a hard-wired reason we lust after it, and a microscopic explanation for why it shines. We reveal how the science behind our favorite metal drives men across oceans and continents, and how a difference in the way it's used in each hemisphere leads to a clash of civilizations.
