Slide10: In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds. -Albert Einstein Some Reference materials: National Science Foundation web site American Association of Physics Teachers web site University of Maryland Physics Question of the Week web site: Some Reference materials: National Science Foundation web site American Association of Physics Teachers web site University of Maryland Physics Question of the Week web siteSlide12: Topics for this evening: Brownian Motion The Photoelectric Effect RelativitySlide13: Brownian motion: is the small molecular motion inherent in all molecules, even at the lowest possible temperature.Discovered by botanist Robert Browne (1773-1858) “..in 1827.
