Logarithms. Slide rules are based on the concept of logarithms. Although a knowledge of logarithms it is not necessary to be able to use a slide rule, it does help you to understand what you are doing. If you multiply a number raised to two different powers, the result is equal to the same number raised to the sum of the powers. Logarithms book for beginners and high school students on solving logarithms. Explaining Logarithms by Dan Umbarger. ISBN (color) ISBN (b & w). A logarithm is an exponent. log 10 10, = 4. "The logarithm of 10, with base 10 is 4." 4 is the exponent to which 10 must be raised to prod "10 4 = 10," is called the exponential form. "log 10 10, = 4" is called the logarithmic form. Here is the definition: log bx = n means bn = x. That base with that exponent produces x.

In his second book, Joint Slide Rules: Sectors, 2-foot 2-fold and similar slide rules, expert Peter M. Hopp examines the joint rule, completing an important but neglected part of slide rule history. The book is a comprehensive account of joint rules and contains detailed information on over two hundred joint slide rule makers from around the world. This is the fundamental identity underlying all slide rule calculations, and it is worth stating prominently: It's convenient to think of the logarithm as the common (base 10) logarithm, and the length of the slide rule as one unit, but you can also think of log meaning the natural logarithm, and the length of the slide rule being log(10) units. So of course, \(2^{\log n} = n\) when the base of the log is 2. (this is simply logarithm property (1)). A slide rule measures the length of the logarithm for the numbers, lets you slide bars representing these lengths to add up the total length, and finally converts this total length to the correct numeric answer by taking the inverse of. If you're interested in slide rules but not very familiar with their use, you will find this book helpful and informative. It starts slowly, explaining what a logarithm (log) is and how slide rules use logs to enable multiplication and division. From there, it goes on to explain the use of 5/5(3).
