Revisiting the Mousetrap Experiment: Not Just About Nuclear Chain Reactions
Abstract
We present quantitative measurements on a classic experiment proposed for the first time in 1947 to illustrate the phenomenon of a chain reaction in nuclear fission. The experiment involves a number of mousetraps loaded with solid balls. Once one trap is made to snap, it releases two balls that cause other traps to snap more traps and the result is a chain reaction. We report for the first time that the mousetrap experiment can be fitted by a simple dynamic model. We also discuss the significance of this experiment beyond nuclear chain reactions, as providing insight in a variety of fields involving complex, adaptive systems.
