    Science in the broadest sense refers to any system of knowledge attained by verifiable means.[1] In a more restricted sense, science refers to a system of acquiring knowledge based on empiricism, experimentation, and methodological naturalism, as well as to the organized body of knowledge humans have gained by such research. This article focuses on the meaning of science in the latter sense. Scientists maintain that scientific investigation must adhere to the scientific method, a process for evaluating empirical knowledge that explains observable events in nature as results of natural causes, rejecting supernatural notions. Fields of science are commonly classified along two major lines: Natural sciences, the study of the natural phenomena; Social sciences, the systematic study of human behavior and societies. Mathematics has both similarities and differences compared to other fields of science. It is similar to other sciences, because it is a rigorous, structured study of topics such as quantity, structure, space, and change. It is, however, different in its method of arriving at results. Mathematics as a whole is vital to the sciences — indeed, major advances in mathematics have often led to major advances in other sciences. Certain aspects of mathematics are indispensable for the formation of hypotheses, theories, and laws, both in discovering and describing how things work (natural sciences) and how people think and act (social sciences). Science as defined above is sometimes termed pure science in order to differentiate it from applied science, the latter being the application of scientific research to human needs. The word science comes from the Latin word scientia for knowledge, which in turn comes from scio - I know. The Indo-European root means to discern or to separate, akin to Sanskrit chyati, he cuts off, Greek schizein, to split, Latin scindere, to split. From the Middle Ages to the Enlightenment, science or scientia meant any systematic or exact recorded knowledge. Science therefore had the same sort of very broad meaning that philosophy had at that time. In some languages, including French, Spanish, Portuguese, and Italian, the word corresponding to science still carries this meaning. From classical times until the advent of the modern era, philosophy was divided into natural philosophy and moral philosophy. In the 1800s, the term natural philosophy gradually gave way to the term natural science. Natural science was gradually specialized to its current domain, which typically includes the physical sciences and biological sciences. The social sciences, inheriting portions of the realm of moral philosophy, are currently also included under the auspices of science to the extent that these disciplines use empirical methods. As currently understood, moral philosophy still retains the study of ethics, regarded as a branch of philosophy and one of the three classical normative sciences.
