1. The Age Equation

---

Origin Story

As a geochronologist, I always find myself momentarily flummoxed when asked how you get from something that looks like $N=N_oe^{-\lambda t}$ to something that looks like $n = n_o + N \left( e^{\lambda t} - 1 \right)$. Why is the $\lambda$ positive now? Why do we subtract 1? My answer is always, Hold on, let me do all of this math from scratch again to try to make sense of it.

There are some textbooks out there that do a pretty good job, but the math is often scattered across pages with additional information that is useful, but extraneous to my immediate needs. And this is just for a generic equation. What about derivations specific to certain decay systems?

Hence, a most ambitious and reckless project to collapse context, derivation, and application of radiometric decay equations into single page primers.

Hope this helps you as much as it has helped us,
