- How does a computer/calculator compute logarithms? (zachartrand.github.io)
There are many functions on a scientific or graphing calculator that we are introduced to as high school students that, we are told, just work. You select the function, put in the value that you need to calculate, hit “=” or “ENTER”, and SHABAM! You have the correct answer to some arbitrary number of digits that you are ensured are all 100% accurate.

An online book-in-progress by Charles Petzold wherein is explored the utility, history, and ubiquity of that marvelous invention, logarithms including what the hell they are; with some demonstrations of their primary historical application in plane and spherical trigonometry.
- Daniel Webster (Wikipedia)
Daniel Webster (January 18, 1782 – October 24, 1852) was an American lawyer and statesman who represented New Hampshire and Massachusetts in the U.S. Congress and served as the 14th and 19th U.S. Secretary of State under Presidents William Henry Harrison, John Tyler, and Millard Fillmore. Webster was one of the most prominent American lawyers of the 19th century, arguing over 200 cases before the United States Supreme Court in his career. During his life, Webster had been a member of the Federalist Party, the National Republican Party, and the Whig Party. He was among the three members of the Great Triumvirate along with Henry Clay and John C. Calhoun.

When it comes to the relationship ab=c, we have examined how c can be thought of as a combination of a and b. We have also considered the implications of thinking of a as a combination of b and c. There is one more possible combination we could contemplate – what happens if we view b as a combination of a and c?

In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 10^3, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. The logarithm of x to base b is denoted as logb (x), or without parentheses, logb x, or even without the explicit base, log x, when no confusion is possible, or when the base does not matter such as in big O notation.
