Edward Lorenz

Definition

Edward Lorenz was a pioneering American mathematician and meteorologist, best known for his work in chaos theory and the concept of the butterfly effect. His research laid the groundwork for understanding complex systems, including how small changes in initial conditions can lead to vastly different outcomes in chaotic systems, which is highly relevant in the study of magnetosphere-ionosphere coupling.
