It was no less than Aristotle himself who wondered “Why are the stones on the seashore which are called pebbles round, when they are originally made from long stones and shells?”
In typical Aristotlean fashion, he not only asked the question, but went on to provide a very plausible explanation (see appendix below)
– one which lay untested for more than 2000 years. It now been verified in practice by professor Douglas Durian and his Durian Research Group
at the University of Pennsylvania, Philadelphia, US.
