When I look at the cover of Time Magazine http://img.timeinc.net/time/magazine/archive/covers/1946/1101460701_400.jpg it reads Einstein's 1905 paper equates to Atomic Bomb, not relativity. Albert Einstein didn't want to do a Relativity experiment, he want to do an Atomic Bomb experiment. http://img.timeinc.net/time/magazine/archive/covers/1946/1101460701_400.jpg If you girls cannot understand Einstein's 1905 paper, surely you can understand a picture of it: http://img.timeinc.net/time/magazine/archive/covers/1946/1101460701_400.jpg -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.
