This is a straightforward account of an interesting scientist of our times. The invented dialogue is not obtrusive. It is the sort that serves to get the salt passed. As is often the case in biographies for this age level, the subject is made to muse aloud. This overworked device must have a multitude of the literal minded convinced that all great men blab to themselves constantly. However, all things considered, this is a sprightly record of a life that encountered great difficulties and many setbacks with admirable equanimity.
