The Electric Age making available the vast stores of energy contained in coal, wood, and oil. By burning fuel, chemical energy is converted into heat energy, which in turn can be used to boil water to produce steam. By letting the steam expand against a piston or a turbine blade, heat energy can be converted to mec

Electromagnetic Waveswas to introduce Wheatstone to the audience. At the last minute, just as Faraday and Wheatstone were about to enter the lecture hall, Wheatstone got stage fright, turned around, and ran out into the street. Faraday had to improvise and give a lecture himself. Normally, Faraday discussed in public on

Probing the Atome during the nineteenth century in attributing the thermodynamic laws and some of the properties of matter, especially gases, to the kinetic-molecular theory (Chapter 7). In addition, it was known for centuries that there are different types of so-called fundamental “elements” in nature—gold, silver

The Quantum Model of the Atomt elements. Physicists knew from Maxwell’s theory that light is emitted and absorbed only by accelerating charges. This suggested that the atom might contain moving charges. Patterns and regularities in the properties of the light emitted we expected to provide valuable clues about the precise natur

Solids Matterroperties of matter and radiation, the fundamental constituents of the Universe. The new physics also enabled an amazing variety of technological applications that are continuing to transform our lives—from lasers and microchip transistors to new medical imaging devices, and a host of new materials.

Probing the Nucleusarged electrons. Experiments on the scattering of a particles revealed that the nucleus has dimensions of the order of 10. m. Since the diameter of an atom is of the order of 10. m, the nucleus takes up only a minute fraction of the volume of an atom. The nucleus, however, contains nearly all of the

Electromagnetic Wavesly his actual experiments. But on this occasion he revealed certain speculations which, as he later admitted, he would never have made public had he not suddenly been forced to speak for an hour—although these speculations soon changed physics.
