READING PASSAGE : Science
Science and collecting Science, meaning knowledge, is a systematic method that builds and organizes knowledge in the form of testable interpretations and expectations about the universe.
Guessing modern science is divided into three main branches consisting of natural sciences, such as biology, physics and chemistry, which study nature in the broadest sense, and social sciences, such as economics, psychology, and sociology, which study the science of individuals and societies, and formal sciences such as logic, mathematics, and theoretical computer sciences, which study abstract concepts. Disciplines that use current scientific knowledge for practical purposes, such as applied engineering and medicine, are described as applied sciences.
Science depends on research that is usually conducted in academic and research institutions, as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of scientific policies that seek to influence the scientific institution by giving priority to the development of commercial products, health care, weapons and the environment.
