This series helps teachers demystify physics by showing students what it looks like. Field trips to hot-air balloon events, symphony concerts, bicycle shops, and other locales make complex concepts more accessible. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance, while historical reenactments of the studies of Newton, Leibniz, Maxwell, and others trace the evolution of theories. The Mechanical Universe helps meet different students' needs, from the basic requirements of liberal arts students to the rigorous demands of science and engineering majors. This series is also valuable for teacher professional development. Produced by the California Institute of Technology and Intelecom. 1985. By the 1860s all the pieces of the electricity and magnetism puzzle were in place, except one. The last piece, discovered by James Clerk Maxwell and called (unfortunately) the displacement current was just what was needed to produce electromagnetic waves called (among other things) light. Instructional Objectives * Be able to write down Maxwell's equations and discuss the experimental basis of each. * Be able to state the definition of Maxwell's displacement current and discuss its significance. * Realize that Maxwell's equations reveal that light is an electromagnetic wave. * Be able to state the expression for the speed of an electromagnetic wave in terms of electric and magnetic currents. * Be able to comment on the symmetry of Maxwell's equations. * Know the significance of Maxwell's equations in modern technological society
