In various contexts, decay refers to the gradual deterioration or decline of a substance, structure, or system over time. In physics and chemistry, radioactive decay pertains to the spontaneous disintegration of unstable atomic nuclei, emitting radiation in the form of particles or electromagnetic waves. This process transforms the nucleus into a more stable configuration, often involving the emission of alpha or beta particles. Decay is also used in mathematics to describe the reduction or diminishing of a quantity or value over successive iterations or intervals. In biology, decay signifies the decomposition of organic matter by microorganisms, ultimately returning nutrients to the ecosystem. In broader terms, decay encompasses a natural process of transformation and change observed across various scientific, School Management System environmental, and societal domains.
