Our universe Book

Totally unreadable -- even if you are an expert on the contents by profession, you will find the methods archaic and the notation obfuscatory -- but five stars for being full of genius. The brief section from Einstein is more accessible, as are Hawking's commentaries, but Copernicus, Galileo, Kepler, and Newton are very difficult indeed. It is, however, pretty neat to see what these important original works looked like.
