Heaviside

The Heaviside function, named after mathematician Oliver Heaviside, is a mathematical tool that models a sudden change or switch. It’s like a light switch that turns from off (0) to on (1) instantly at a certain point, usually zero. For example, it can represent the moment when a voltage suddenly appears in an electrical circuit. The function is useful in engineering and physics for describing systems with abrupt transitions, such as switching signals or step changes in behavior. Although it’s a simple concept, it helps analyze and solve complex problems involving sudden shifts.
