<blockquote>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 [[basic_tools:exponential_function|exponent]] already. | <blockquote>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 [[basic_tools:exponential_function|exponent]] already. | ||
But there’s a fresh, intuitive explanation: The natural log gives you the time needed to reach a certain level of growth. | But there’s a fresh, intuitive explanation: The natural log gives you the time needed to reach a certain level of growth. | ||

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