| logarithm | <mathematics> One of a class of auxiliary numbers, devised by John Napier, of Merchiston, Scotland (1550-1617), to abridge arithmetical calculations, by the use of addition and subtraction in place of multiplication and division. The relation of logarithms to common numbers is that of numbers in an arithmetical series to corresponding numbers in a geometrical series, so that sums and differences of the former indicate respectively products and quotients of the latter; thus 0 1 2 3 4 Indices or logarithms 1 10 100 1000 10,000 Numbers in geometrical progression Hence, the logarithm of any given number is the exponent of a power to which another given invariable number, called the base, must be raised in order to produce that given number. Thus, let 10 be the base, then 2 is the logarithm of 100, because 10^2 = 100, and 3 is the logarithm of 1,000, because 10^3 = 1,000. Arithmetical complement of a logarithm, the difference between a logarithm and the number ten. Binary logarithms. See Binary. Common logarithms, or Brigg's logarithms, logarithms of which the base is 10; so called from Henry Briggs, who invented them. Gauss's logarithms, tables of logarithms constructed for facilitating the operation of finding the logarithm of the sum of difference of two quantities from the logarithms of the quantities, one entry of those tables and two additions or subtractions answering the purpose of three entries of the common tables and one addition or subtraction. They were suggested by the celebrated German mathematician Karl Friedrich Gauss (died in 1855), and are of great service in many astronomical computations. Hyperbolic, or Napierian, logarithms, those logarithms (devised by John Speidell, 1619) of which the base is 2.7182818; so called from Napier, the inventor of logarithms.

| logarithmic phase | <cell culture> The steepest slope of the growth curve of a culture--the phase of vigorous growth during which cell number doubles every 20-30 minutes. (15 Nov 1997) |
| logarithmical | Of or pertaining to logarithms; consisting of logarithms. <mathematics> Logarithmic curve, a curve which, referred to a system of rectangular coordinate axes, is such that the ordinate of any point will be the logarithm of its abscissa. Logarithmic spiral, a spiral curve such that radii drawn from its pole or eye at equal angles with each other are in continual proportion. See Spiral. Origin: F. Logarithmique.

The logarithm of any positive number n to the base b is the power l to which that base must be raised in order to satisfy the identity n = b l : l = log b n. Logarithms to the base 10 are called common logarithms and written log or log 10 . Logarithms to the base e = 2.7182818284 . . . are called natural (Napierian, hyperbolic) logarithms, and are often written log e or ln. The natural logarithms are the more convenient in any computations involving differentiation

We call the b positive number's a based (a > 0; a cannot equal with 1) logarithm that exponent, which we get, if we raise a to the b th power. Symbol: a^log a b = b; The natural logarithm: 10^lg b = b (The ^ sign means raising to a higher power)

| logarithm |
formally, the number of times ten must be multiplied with itself to equal a certain number. For example, log 5 is 100,000 (10 x 10 x 10 x 10 x 10). VIRAL LOAD is often reported in terms of log. In addition, logs are used to measure changes in viral load. For example, a reduction in viral load from 100,000 to 1,000 copies/ml is a 2.0 log (or 99 percent) reduction (100,000 divided by 100 [2.0 log or 10 x 10] equals 1,000). ...
