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

What is science?

Science is any systemic learning from testable experiments to getting the knowledge of physical or chemical phenomena occurring in our universe or environment. Science divided into many branches. Physics, chemistry, biology are the main branches of science. Other branches are medicinal, environmental, nuclear science, etc. In this part of the category, we discuss topics related to chemistry.
