Did you know?
Did you know...... that on December 24, besides being Christmas Eve, is Gravity Day? This day celebrates the birthday of Isaac Newton (1642 according to the old style calendar), the first to describe gravity. He was born at Woolsthorpe, England on January 4, 1643 (according to the new style calendar). Happy birthday, Isaac!
