# Logarithm

## Intuitive

Given how the natural log is described in math books, there’s little “natural” about it: it’s defined as the inverse of $e^x$, a strange enough exponent already.

But there’s a fresh, intuitive explanation: The natural log gives you the time needed to reach a certain level of growth. Demystifying the Natural Logarithm (ln) by Kalid Azad

## Abstract

Some things go up really fast, like the number of cases of coronavirus in March. Some things go down really fast, like the stock market in March.

Logarithms are a way to flatten exponential curves, so we can see and understand their structure, even when dealing with extreme/exponential growth.

The motto in this section is: the higher the level of abstraction, the better.
