Predicting the Unpredictable: The Mathematics of Radioactive Decay
In short: How do we measure the lifespan of an atom when its death is impossible to schedule? This video explores why probability, rather than certainty, governs the behavior of radioactive nuclei.
Paul Andersen explains that while it is impossible to determine the exact moment a single nucleus will decay, scientists use probability to predict behavior across large groups. This leads to the concept of half-life: the specific duration required for 50% of a radioactive sample to decay.
The video details how nuclei release alpha, beta, or gamma particles during this process. The rate of these transitions is dictated by a specific decay constant, which determines the unique half-life of different isotopes.
