:At the close of my sophomore year ' my Greek professor ' asked me to teach the course in elementary physics in the preparatory department during the next year. To my reply that I did not know any physics at all, his answer was, ?Anyone who can do well in my Greek can teach physics.? ?All right,? said I, ?you will have to take the consequences, but I will try and see what I can do with it.? I at once purchased an Avery?s Elements of Physics, and spent the greater part of my summer vacation of 1889 at home ? trying to master the subject. ' I doubt if I have ever taught better in my life than in my first course in physics in 1889. I was so intensely interested in keeping my knowledge ahead of that of the class that they may have caught some of my own interest and enthusiasm.
