“ When we first arrived at the school we received an extended introduction detailing what a wonderful place it was and how lucky we were to be there. But no one explained exactly why we were to be there. Yes, we understood the general objective was to accumulate knowledge, although learning Shakespeare and algebra did not strike us as particularly helpful to our future lives. I've yet to meet a single person who found a use for algebra in later life. The excuse proffered was that it developed intelligence. It struck me as extremely unintelligent not to give us the opportunity to study subjects that would be of practical use as well as develop our intelligence. I learned Boyle's law and Ohm's law parrot fashion without having a clue as to their meaning, yet left the school five years later incapable of changing a fuse or wiring a three-pin plug. Understandably, we formed the general impression that we were there for the same reason we were sent to Sunday school – to keep us out of mischief until we were old enough to work. ”
