"Professor Brown's mathematical meanderings provide more than just entertainment. . . . Brown takes the mystery out of calculating interest on your money, converting Fahrenheit to Celsius and interpreting daily values on food labels. You'll enjoy numerous other examples of the fascinating use of numbers ranging from risk analysis to how GPS works. You can count on it."
— Dr. Joe Schwarcz
