(p.1) 1 What You Need to Know to Read This Book
The Logician and the Engineer

Paul J. Nahin

Princeton University Press

This chapter details the background knowledge needed to read this book. Specifically, it assumes some knowledge of mathematics and electrical physics and an appreciation for the value of analytical reasoning—but no more than a technically minded college-prep high school junior or senior would have. In particular, the math level is that of algebra, including knowing how matrices multiply. The electrical background is simple: knowing (1) that electricity comes in two polarities (positive and negative) and that electrical charges of like polarity repel and of opposite polarity attract; and (2) understanding Ohm's law for resistors (that the voltage drop across a resistor in volts is the current through the resistor in amperes times the resistance in ohms) and the circuit laws of Kirchhoff (that the sum of the voltage drops around any closed loop is zero, which is an expression of the conservation of energy; the sum of all the currents into any node is zero).

Keywords:   Boolean algebra, Boolean logic, mathematics
