Alpha decay represents a fundamental mode of radioactive disintegration wherein an unstable nucleus emits an alpha particle—a tightly bound cluster of two protons and two neutrons. This process not ...

Physicists in France have measured the longest ever radioactive half-life - over twenty billion billion years - in a naturally occurring element that decays by emitting alpha-particles. Nőel Coron and ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.
