    But think of the golf, or tennis!

    Indeed there are many misconceptions in text books. A quote from the new Edexcel Year1 A level mechanics book: "As the force of gravity does not depend on mass...."

    Many other misconceptions in text books are more in the nature of simplifications. I find it difficult teaching pupils that metals are malleable because the layers of atoms are easily able to slide over each other. My degree is in metallurgy and materials. One of our first lectures was a calculation showing the enormous force which would be required for this to happen and explaining metals actually deform by the movement of crystal defects called dislocations.

    Actually Alan Shepard (Apollo 14 commander) did play golf on the moon, or at least he hit a couple of golf balls which went a very long way.

    Thank you, very comprehensive, although I'm not sure how many people would agree that school produces enjoyment.
