Physical systems research involves studying the behavior and dynamics of complex physical systems. This can include systems at various scales, ranging from microscopic particles to large-scale structures like buildings or bridges. Researchers in this area use principles from physics, engineering, and mathematics to understand how these systems function, interact, and respond to external stimuli. Areas of study within physical systems research can include dynamics, control theory, chaos theory, and system optimization. The ultimate goal of this research is to develop better models and tools for analyzing and designing physical systems for a wide range of applications, from transportation and energy systems to biomedicine and environmental science.
