Visual representation of the Logarithmic timeline in the scale of the universe. This timeline shows the whole history of the universe, the Earth, and mankind in one table. Each row is defined in years ago, that is, years before the present date, with the earliest times at the top of the chart. In each table cell on the right, references to ...
A logarithmic timeline is a timeline laid out according to a logarithmic scale. This necessarily implies a zero point and an infinity point, neither of which can be displayed. The most natural zero point is the Big Bang, looking forward, but the most common is the ever-changing present, looking backward. (Also possible is a zero point in the ...
He then called the logarithm, with this number as base, the natural logarithm. As noted by Howard Eves, "One of the anomalies in the history of mathematics is the fact that logarithms were discovered before exponents were in use." [16] Carl B. Boyer wrote, "Euler was among the first to treat logarithms as exponents, in the manner now so ...

In mathematics, the logarithm to base b is the inverse function of exponentiation with base b. 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 of 1000 is 3, or log 10 (1000) = 3.
1614 – John Napier develops method for performing calculations using logarithms; 1671 – Newton–Raphson method developed by Isaac Newton; 1690 – Newton–Raphson method independently developed by Joseph Raphson; 1706 – John Machin develops a quickly converging inverse-tangent series for π and computes π to 100 decimal places
By the nature of a logarithmic timeline, the last row covers the shortest period (say, one year). The second-but-last row, if we're going to stick with the unintuitive 10^0.1, will then be 1.26 years. This is supposed to be a logarithmic timescale, so it should be done properly (or not at all). --dab 13:58, 15 May 2009 (UTC)
Logarithms can be used to make calculations easier. For example, two numbers can be multiplied just by using a logarithm table and adding. These are often known as logarithmic properties, which are documented in the table below. [2] The first three operations below assume that x = b c and/or y = b d, so that log b (x) = c and log b (y) = d.
