Science is a systematic approach that constructs and organize scientific information in the form of predictions and testable predictions about the natural world. The field of science has an enormous range of sub-disciplines such as life sciences, physical sciences, cognitive science, social sciences etc. A large number of journals are published on all these aspects of science each year. There is enormous diversity in the area of science and the subject matter is extremely broad, ranging from the study of stars and galaxies to the study of the human brain and nervous system.
The modern discipline of science has developed over the years in response to challenges from numerous different fields of study. In recent decades, with the development of new technologies and applications for many fields of science, the scope of scientific research has also widened. There has been tremendous progress in various fields of science like microbiology, genetics, biochemistry, physiology, physics, astronomy etc. However, in all these fields, there are still vast areas of research that have yet to be covered. Some of the areas of current interest are life sciences, cognitive science, social sciences and the physical sciences.
The discipline of science is widely popular among students in colleges and schools, as it provides a framework to understand the nature works. For example, physics teaches us how things work and how they interact with one another. Biology and chemistry are important for understanding the functioning of living organisms. In order to understand the behavior of diverse living organisms, a detailed knowledge of the scientific method is required.
One way to get a clear picture of how science happens is to understand the conceptual model of science. This model helps students understand how the natural world works and how various scientific methods are applied. A good way to grasp how science happens is to adopt the Cartesian view, which postulates that science is a systematic way of obtaining knowledge about nature works by the use of unifying concepts that can be applied independently of each other.
A good way to understand science is to start from objects and how they stand in space. How do objects fall? What causes them to move? How do they interact with gravity? Science textbooks usually explain each question and try to give readers an answer by means of illustrations or theories. However, once a student has understood the conceptual model of science, then he/she can simply ask how something looks like, how it moves and what its shape or size or other properties are.
There are many theories in science that help us better understand nature. Some of these theories are observational sciences which study how things look, behave and change over time. Explorative science deals with how science actually occurs by investigating how new forms of knowledge form. A good example of a form of observational science is genetics where genetic similarities between species are revealed through the accumulated evidence.
