The constant e

  1. Dec 15, 2004 #1
    I am currently learning about logarithms and I understand that Log base e (or Ln) comes up quite often in solutions of logarithms

    However, I also heard that it is a number that comes up often in nature

    Are there any good examples of "e" in nature?

    Euler's number will arise in any process in which the rate of change of a quantity is proportional to the quantity itself. Radioactive decay, Newton's Law of Cooling, Population Growth models and continuous compounding of interest are a few examples.

    Attenuation of wave intensity (light, sound, quantum etc.) when it is absorbed is another important example.
