Common Logarithm - History

History

Common logarithms are sometimes also called "Briggsian logarithms" after Henry Briggs, a 17th-century British mathematician.

Because base 10 logarithms were most useful for computations, engineers generally simply wrote "log(x)" when they meant log10(x). Mathematicians, on the other hand, wrote "log(x)" when they meant loge(x) for the natural logarithm. Today, both notations are found. Since hand-held electronic calculators are designed by engineers rather than mathematicians, it became customary that they follow engineers' notation. So the notation, according to which one writes "ln(x)" when the natural logarithm is intended, may have been further popularized by the very invention that made the use of "common logarithms" far less common, electronic calculators.

Famous quotes containing the word history:

    “Literary works cannot be taken over like factories, or literary forms of expression like industrial methods. Realist writing, of which history offers many widely varying examples, is likewise conditioned by the question of how, when and for what class it is made use of.”
    —Bertolt Brecht (1898–1956)

    “There is nothing truer than myth: history, in its attempt to “realize” myth, distorts it, stops halfway; when history claims to have “succeeded” this is nothing but humbug and mystification. Everything we dream is “realizable.” Reality does not have to be: it is simply what it is.”
    —Eugène Ionesco (b. 1912)

    “The reverence for the Scriptures is an element of civilization, for thus has the history of the world been preserved, and is preserved.”
    —Ralph Waldo Emerson (1803–1882)
