Re: history of logarithm
There's a good entry about logarithms in Wikipedia. It's got a paragraph about their history if you scroll down.
Why did the vector cross the road?
It wanted to be normal.

Re: history of logarithm
applying logarithms into a complicated function can make the function much easier. for example:
y= [x^(3/4)√ (x² + 1)]/(3x + 2)^5
apply log to both sides
lny = 3/4lnx + 1/2lx(x² + 1) - 5ln(3x + 2)
all we gotta do now is add and subtract which is much easier than the original one.
