static electricity and how it related to atoms. THE CONNECTION WITH MAGNETISM In the 17th century scientists believed electrical and magnetic forces were completely separate until, in the 1870s, British physicist James Clerk Maxwell proved they were both forms of a single phenomenon: electromagnetism 166–67 gg. THE FORMS OF ELECTRIC FIELDS In 1839 British scientist Michael Faraday 170–71 ggvisualized the shapes of electric fields and proved that static and current electricity were different

atoms and molecules, scientists began to understand heat as a form of energy. When an object slows down because of friction, for example, the energy of the moving object is not lost—it is merely transferred as heat to the atoms and molecules of the object and its surroundings. In other words, the energy of motion, kinetic energy, changes to thermal (heat) energy. During the 1840s scientists realized that energy can neither be created nor destroyed, an idea investigated by the English scientist

formulated during a revolution in scientific thinking—the birth of experimental science—and are upheld today by the world’s scientific societies. $Recording observations Good science needs precise recording of information. These notes by the French mathematician and physicist, André-Marie Ampère, concern the magnetic properties of electrical current. &Testing theories Scientists must design experiments that are open—not to prove a preconceived theory but if possible to disprove it.

between. Polarizing filters act by absorbing the waves oscillating in one direction only, Light-bending materials Polarizing filter When light passes from one material into another, for example from air into glass or water, it changes direction; light is refracted (bent) as it goes through the interface. This refraction makes ponds look shallower than they really are, and can make a spoon appear bent when it stands in a glass of water. Light travels more slowly through denser materials, such as
