Science is an empirical cumulative, and systematic approach to the field of science concerned with the observations and results of scientific methods and research. A branch of Physics, it deals with the physical laws and principles that govern the behavior of real objects as observed experimentally and by experiment. It is logically organized around the field of physics and encompasses many related areas including astronomy, mathematics, and earth sciences. It includes numerous subtopics such as research, analysis, and new studies in diverse areas. The discipline of science is continuously growing, changing, and advancing through the practice of research, investigation, and observation.
Science is an empirical cumulative, and systematic approach to the study of nature and the universe. It is rational and can be measured, examined, and tested. Scientific theories are tested against observational evidence in order to verify the existence and properties of a reality that has previously been thought to be unobtainable, and to determine if the theory is actually true. It is based on the principle of naturalism that science is able to explain any phenomena that can be observed and tested independently of human intervention.
The fields of biology, chemistry, physics, and chemistry each have their own unique areas of research and study. Within these branches of science, there are two main categories: life science and physical science. Life science is the area of study that attempts to understand how living things are structured and how they function. The focus of life science research is to discover the relationships among living things and to discover how their systems work to create and maintain their environment. A strong example of a subcategory of life science is microbial biology, which studies the genetic structure and development of all forms of life. Although microorganisms cannot speak, they are the basis of all life on earth, and research into their origins and structure has profoundly improved our understanding of disease and illness.
Physical science deals with the world around us and the laws that govern it. One major subfield within physical science is physics, which seeks to describe the workings of the physical universe and the laws that govern it. Physics can be applied to a wide variety of areas beyond human understanding, including astronomy, cosmology, and particle physics. A major branch of physical science is mathematics, which uses calculations to describe the behavior of objects and the laws that govern them. Math is used in everything from mechanics to computer science. Although not considered a subcategory of physical science, chemical science deals mainly with the properties of matter and how they interact with one another.
Natural science, as its name suggests, is the area of study that is independent of science as we understand it. It therefore combines elements of both science and art in order to understand the relationship between the two. The most obvious example of a subfield of natural science is paleontology, which involves the study of prehistoric bones. Art, as we understand it today, would not have been possible without the results of paleontology, and paleontologists have made significant contributions to our knowledge of natural history.
We have been discussing only a small part of the broad range of fields of science. When you finish reading this article, you will understand that there are many more subfields within science. These fields have their own specific purposes, and their own unique areas of study. For example, although biology is a subfield of natural science, it also has its own specific branches, such as virology and microbiology, which to many may seem quite unrelated, yet they share some fundamental principles.
