EINSTEIN'S THEORY TO BE EXPLAINED.
Byline: Carol Rock Staff Writer VALENCIA  Call it ``Physics for Dummies.'' Participants in a free presentation about Einstein's theory of relativity April 12 are promised a clearer understanding of one of science's most profound theories. The presentation will begin at 7 p.m. April 12 in the cafeteria at College of the Canyons. The speaker will be retired NASA astronomer Skip Newhall, who worked at Jet Propulsion Laboratory for 35 years. During his career, Newhall worked on spacecraft navigation and orbit determination, verylong baseline interferometry and lunar laser ranging. Newhall will explain Albert Einstein's theory of relativity in a talk titled ``Special Relativity for NonScientists.'' His illustrated, nontechnical presentation will cover the speed of light and when it can and cannot be exceeded; the slowing of the rates of moving clocks; the apparent contraction of the length of moving objects; the three speeds defined by relativity, and a layman's explanation of Einstein's equation E=MC2. Newhall will discuss what it means, where it comes from and why it has to be. The talk is scheduled on the 100th anniversary of Einstein's introduction of the theory of special relativity, which he refined in 1916 in more complete form as general relativity. The theory forced a fundamental reevaluation of the workings of the universe. The program is presented by the Mathematics, Engineering, Science Achievement (MESA) program at College of the Canyons. Refreshments will be served. For more information, call Susan Crowther at the college, (661) 3623448 or email susan.crowther(at)canyons.edu. Carol Rock, (661) 2575252 carol.rock(at)dailynews.com
