His (Galileo's) father was an impoverished mathematician, and did his utmost to turn the boy towards what he hoped would prove more lucrative studies. He successfully prevented Galileo from even knowing that there was such a subject as mathematics until, at the age of nineteen, he happened, as an eavesdropper, to overhear a lecture on geometry. He seized with avidity upon the subject, which had for him all the charm of forbidden fruit. Unfortunately the moral of this incident has been lost upon schoolmasters.
