A random walk is a mathematical concept that describes a path consisting of a series of random steps. Imagine a person taking steps in different directions, where each step is determined by chance. This idea can be applied to various fields, such as physics, finance, and ecology, to model unpredictable behaviors, like stock market fluctuations or animal movements in nature.
In a random walk, the future position of the walker is uncertain and depends on the previous steps taken. This randomness can lead to interesting patterns and behaviors, making it a valuable tool for understanding complex systems, such as the spread of diseases or the behavior of particles in physics.
