It was once thought that the motion of atoms and subatomic particles could be ex-pressed using classical mechanics, the laws of motion introduced in the seventeenthcentury by Isaac Newton, for these laws were very successful at explaining the motionof everyday objects and planets. However, towards the end of the nineteenth century,experimental evidence accumulated showing that classical mechanics failed when itwas applied to particles as small as electrons, and it took until the 1920s to discover theappropriate concepts and equations for describing them. We describe the concepts ofthis new mechanics, which is called quantum mechanics, in this chapter, and applythem throughout the remainder of the text.
