Pure & Applied Science

Science is a systematic enterprise that builds and organizes knowledge in the form of explanations and predictions about the universe. In an older and closely related meaning, “science” also refers to this body of knowledge itself, of the type that can be rationally explained and reliably applied. In modern usage however, “science” most often refers to a way of pursuing knowledge, not only the knowledge itself. It is also often restricted to those branches of study that seek to explain the phenomena of the material universe.

Science can be broadly classified into 2 types- BASIC SCIENCE and APPLIED SCIENCE.

Basic science or “pure” science seeks to expand knowledge regardless of the short-term application of that knowledge. It is not focused on developing a product or a service of immediate public or commercial value. The goal of basic science is knowledge for knowledge’s sake, though this does not mean that, in the end, it may not result in a practical application.

In contrast, applied science or “technology” aims to use science to solve real-world problems such as improving crop yields, finding a cure for a particular disease, or saving animals threatened by a natural disaster. Many scientists think that a basic understanding of science is necessary before an application is developed; therefore, applied science relies on the results generated through basic science.
