I searched the web for a document that contain history of logarithm but didn't find an iteresting thing!

Is there a savier?

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.

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.
