Light attenuation and exponential laws
This particular base value is denoted e, and is approximately 2.71828. Light attenuation To get a feel for how exponentiality manifests itself physically, let’s look at how light (or any electromagnetic radiation, including, for example, X-rays), decays in its brightness (intensity) through a medium.

Important Mathematical Constants
It’s value has been estimated at about 2.71828 … While it is still uncertain to mathematician just why this number is so important, it surely is. It, also like pi, is used in a surprising number of real-world applications. It is the key, in fact, to such common

 · It is approximately equal to 2.71828 So there you go. If you are all mathy (yes, I know that isn’t a word) and geeky, you should hack into some Chromebooks and take some of Google’s sponsorship money.
Logarithm
Logarithms or logs are a part of mathematics. They are related to exponential functions. A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation. Historically, they were useful in multiplying or dividing large numbers. An example of a logarithm is log 2 ⁡ ( 8

Element analysis: a wavelet-based method for analysing …

At the other extreme, for signals that are nearly singular in nature, the ‘modulus maxima’ method [2,6] has proved useful. These popular methods represent the signal as being supported entirely on nearly horizontal, or nearly vertical, curves on the time/scale
i Power i: What Is i Raised To The Power i?
While learning complex analysis, one learns that exponential with respect to i does not have a single, fixed value. Rather, the function is a multi-valued. Imaginary numbers live in a world of their own; the numbers are counted on an entirely different plane or axis that is solely devised for them.
