Publisher's Notes
First Line: "To any machine, work is a matter of principle, because everything a machine does is in accordance with a set of principles or scientific laws. To see the way a machine works, you can take the covers off and look inside. But to understand what goes on, you need to get to know the principles that govern its action."
