👉 In physics, "realizations" are events that occur in a system under control. They represent states of motion or conditions that can be observed and measured by the observer or instrument. Realizations are fundamental for understanding physical systems because they provide insight into how the system behaves over time and in response to external forces. Realizations allow us to predict future behavior based on current observations, which is crucial for modeling complex systems. In practice, realizations are often used to analyze phenomena such as fluid dynamics,
