Description: Develops concepts relating to the tools and limitations of physical measurement using the determination of the speed of a rifle bullet as an illustration. William Siebert of M.I.T. follows a step-by-step analysis of the measurement process including the discussion of problems of "noise," bias, use of apparatus, significant figures, and the element of decision found in all problems of measurement., Develops concepts of electrical pressure, current, and resistance, and establishes the need for the measurement of electricity. Demonstrates the measurement of electrical pressure and current flow, shows the development and use of Ohm's law in calculating electrical relationships, and discusses the importance of fuses as a safety measure.
