Herman Trivilino replied to the thread Reconcile poundforce w/slug and lbmass.No. There is no officially-sanctioned definition of the pound-force. The definition of the pound Avoirdupois is 0.453 592 37 kg. The... -
Herman Trivilino replied to the thread I want to help Physics education. What should I do?.Look into the work Eric Mazur did at Harvard University. When he started teaching he was taken aback by student course evaluations that...
