1. What is the definition of “Physics” Webster’s 9 th new Collegiate Dictionary gives: physics [physica, pl, natural science, fr. Gk, of physikos of nature … ] 1. a science that deals with matter and energy and their interactions in the fields of mechanics, acoustic, optics, heat, electricity, magnetism, radiation, atomic structure, and nuclear phenomena

2. The Game of Physics Physics is much like playing a game. The game is to find the rules of nature. We cannot always understand why the rules are what they are, but we can still play the game and test the rules as we play. We test the rules with experiments. Mathematics is used a lot in physics because it communicates the rules of the game in a precise and concise way. As with any other language knowing what certain words and symbols mean is important. For example c is used frequently for the speed of light (3 x 10 8 m/s).

3. Eddy Currents a rule of nature When a magnet is dropped down a metallic tube, the changing magnetic field created by the falling magnet pushes electrons in the metal tube around in circular, eddy-like currents. These eddy currents have their own magnetic field that opposes the fall of the magnet. The magnet falls dramatically slower than it does in ordinary free fall in a nonmetallic tube.

4. “The World Year of Physics 2005 is a United Nations endorsed, international celebration of physics. Events throughout the year will highlight the vitality of physics and its importance in the coming millennium, and will commemorate the pioneering contributions of Albert Einstein in 1905. Through the efforts of a worldwide collaboration of scientific societies, the World Year of Physics brings the excitement of physics to the public and will inspire a new generation of scientists. “ What is the “World Year of Physics 2005” From the “World Year of Physics 2005 Website

5. Why 2005? “In 1905, his year of wonders, Einstein 1) made major contributions to the classical kinetic theory of atoms and molecules; 2) resolved the conflict between classical mechanics and the optics and electrodynamics of moving bodies; and 3) laid the foundations for the quantum theory of light and matter." From a talk by Dr. John Stachel Professor Emeritus of Physics and Director, Center for Einstein Studies Boston University given on Friday, February 4, 2005 8:00 p.m McKenna Hall Auditorium, University of Notre Dame
