## Main Question or Discussion Point

http://en.wikipedia.org/wiki/Exponential_family

I can't count the number of times I've encountered exponential trends in my daily life:

- Productivity

- Skill differences

- Wealth differences

Not even all socioeconomic: You can even find it in nature:

- the energy amplitude of an electron decreasing exponentially as you get away from the center

- your mass increasing as you approach the speed of light

or in business:

- the distribution of the length of phone calls to a call center...

- the salesvolume distribution of various products of a company

- the reasons of why certain products fail (Poisson charts)

There are many more examples (too many to count in other areas of the universe and life).

Why? What is the fundamental principle that is shared by all exponential trends?
