He is a Nobel Laureate who won one quarter of the prize in 2008 "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature."Word of the Day: Range- Since today is Super Bowl Sunday, I thought we'd take a look at projectile motion, which anyone watching the Super Bowl tonight will see plenty of. As the quarterback throws the football, they will be putting an projectile, namely the football, in the air. It will follow the shape of a parabola as it reaches its (hopefully) destined target somewhere downfield. Now, there are many many different critical words relating to this parabola, but today we will talk about the range. Range is the total horizontal distance traversed by the projectile, in tonight's case, the football. The announcers, coaches, players, and referees will be highly concerned with the range of the projectile, aka a "30 yard pass", et cetera. In sports, they don't care much about the maximum height achieved, or the angle of the throw, but rather just how far it has gone, and where it lands. In physics, this is referred to as the range of the projectile. Quote of the Day: "Winning can be defined as the science of being totally prepared" -George AllenKeywords: Kinematics, Range, Football, x-direction
