In what primary fields does science mainly operate?

The primary fields in which science mainly operates include physics and chemistry because these disciplines form the foundation of understanding the natural world. Physics examines the fundamental principles governing matter, energy, and the forces of nature. It encompasses a wide range of phenomena, from the smallest subatomic particles to the vast universe. Chemistry, on the other hand, focuses on the composition, structure, properties, and reactions of matter. It explores how substances interact, combine, and transform, which is essential for understanding the molecular basis of life and various materials.

Together, physics and chemistry provide critical insights into both macroscopic and microscopic processes, making them integral to scientific research and applications. These two fields are interconnected, as concepts from physics often apply to chemical processes and vice versa, which contributes to advancements in technology, medicine, and various scientific endeavors. In contrast, other options lack the broad scientific framework that is integral to scientific understanding and exploration.
