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. 

27. Beyond the Mechanical Universe 
The world of electricity and magnetism, and 20th-century discoveries of relativity and quantum mechanics. 

28. Static Electricity 
Eighteenth-century electricians knew how to spark the interest of an audience with the principles of static electricity. 

29. The Electric Field 
Faraday's vision of lines of constant force in space laid the foundation for the modern force field theory. 

30. Potential and Capacitance 
Franklin proposes a successful theory of the Leyden jar and invents the parallel plate capacitor. 

31. Voltage, Energy, and Force 
When is electricity dangerous or benign, spectacular or useful? 

32. The Electric Battery 
Volta invents the electric battery using the internal properties of different metals. 

33. Electric Circuits 
The work of Wheatstone, Ohm, and Kirchhoff leads to the design and analysis of how current flows. 

34. Magnetism 
Gilbert discovered that the earth behaves like a giant magnet. Modern scientists have learned even more. 

35. The Magnetic Field 
The law of Biot and Sarvart, the force between electric currents, and AmpΦre's law. 

36. Vector Fields and Hydrodynamics 
Force fields have definite properties of their own suitable for scientific study. 

37. Electromagnetic Induction 
The discovery of electromagnetic induction in 1831 creates an important technological breakthrough in the generation of electric power. 

38. Alternating Current 
Electromagnetic induction makes it easy to generate alternating current while transformers make it practical to distribute it over long distances. 

39. Maxwell's Equations 
Maxwell discovers that displacement current produces electromagnetic waves or light.
