Earlier I thougth you were a crackpot. Then I began to suspect
that you werea solid state physicist. (Mind you my ability to
discriminate between the two is rahter limited) But after
reading this I'm inclined to return to my earlier conclusion.

So tell me, when I bake a potato in the oven should the
aluminum foil be wrapped shiny side in?
