natural log 

(MATHEMATICS) a logarithm whose base is e (2.71828...)

The number e is a transcendental irrational, which means that it has infinitely many decimal places but cannot be expressed as a fraction.

A useful feature of the natural log function is that the derivative of (ln x) is 1/x.

The natural log of n is equal to the {log(base x)n} divided by the {log(base x)e}.

Natural Log 

Look in the toilet after #2 and you will find a Natural Log.

Example: Calculus tends to be very fond of Natural Logs. For example, what is the derivative of a natural log? Why is this natural log bigger than this other natural log?

Natural Logico‑Epistemology

A framework that treats logic and epistemology as part of natural science, continuous with psychology, biology, and neuroscience. It argues that logical principles are descriptive of human cognitive processes (or idealizations thereof) rather than transcendent norms. Natural logico‑epistemology studies how humans actually reason, how logical competence develops, and how epistemic norms are grounded in evolutionary adaptation. It challenges the a priori status of logic, making it an empirical subject.

Natural Logico‑Epistemology Example: “Her natural logico‑epistemology research used fMRI to show that people’s performance on syllogisms correlates with neural activity in areas associated with spatial reasoning.”
