what is science like physical, chemical, medical, and environmental science?

Science, any systemic learning from testable experiments to getting the knowledge of physical or chemical phenomena occurring in our universe or environment. Modern science divided into many subdomains. Hence physics, chemistry, biology, natural, medicinal, environmental science, etc are the main subdomain of science.
