In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...

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.
