I want to take the Walter Isaacson biography of Einstein back to the library soon. I am trying very hard to undestand the science, but I don't have the background for it. The explantions are very good and seem simple enough, but they are hard to get your mind around. Of course the Europe of the time (all the famous scientists earning Nobel prizes!) is fascinating, as are the bizarre personal lives of the great savants. We leave in a week and I have a millon little ends I was planning to tie up. These little plans "gang aft agley." Good night.
