I found these quotes http://www.personal.dundee.ac.uk/~kbaar/DrKeithbaar.html
"An
expert is a man who has made all the mistakes which can be made in a very
narrow field." (Niels Bohr)
"There
are two possible outcomes to an experiment: if the result confirms the
hypothesis, then you've made a measurement. If the result is contrary to the
hypothesis, then you've made a discovery." (Enrico Fermi)
