Two guys from Blount County are sittin' in a boat on Douglas Lake fishing and suckin' down beer when all of a sudden Bill says, "I think I'm going to divorce my wife - she hasn't spoken to me in over 6 months."
Earl sips his beer and says, "You better think it over - women like that are hard to find."

Jean Piaget

Born 9 Aug 1896; died 17 Sep 1980 at age 84. Swiss psychologist and zoologist. By age 15 he was contributing articles on molluscs to journals of zoology, and his doctoral degree (1918) thesis was on the distribution of molluscs in the Valaisian Alps. Thereafter, he turned to researching how mental growth develops in several successive stages from infancy to adulthood - “the embryology of intelligence” - for which he became distinguished. In the journal Science (27 Jun 1958), he summarized that at the age of eleven or twelve “a child becomes capable of certain formal or abstract operations of thought which before were possible only as concrete operations on properties of the immediately present object world. This provides the last of three mental revolutions during development.”«
