  2. History of logarithms - Wikipedia

    en.wikipedia.org/wiki/History_of_logarithms

    The history of logarithms is the story of a correspondence (in modern terms, a group isomorphism) between multiplication on the positive real numbers and addition on the real number line that was formalized in seventeenth century Europe and was widely used to simplify calculation until the advent of the digital computer.

  5. Natural logarithm of 2 - Wikipedia

    en.wikipedia.org/wiki/Natural_logarithm_of_2

    The decimal value of the natural logarithm of 2 (sequence A002162 in the OEIS ) is approximately. The logarithm of 2 in other bases is obtained with the formula. The common logarithm in particular is ( OEIS : A007524 ) The inverse of this number is the binary logarithm of 10: ( OEIS : A020862 ). By the Lindemann–Weierstrass theorem, the ...
