  "The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living."
  ( Henri Poincaré)
 
  We shall not cease from exploration
  And the end of all our exploring
  Will be to arrive where we started
  And know the place for the first time.
  (T.S.Eliot)
