About Applied science

Applying scientific knowledge to practical applications, such as technology or innovations, is called applied science.

Basic science, sometimes known as "pure science," is a branch of natural science that focuses on discovering and explaining natural occurrences. Applied science is the process through which this knowledge is put to use in real-world situations. There may be some interaction between fundamental science and applied science. Applied science is often engineering, which generates technology (research and development).


Applied science is the application of scientific principles and findings to real-world problems. Engineers, scientists, and medical professionals all fall under this umbrella. Basic science, on the other hand, aims to advance scientific ideas and principles that explain and predict phenomena in the natural world. The two fields are frequently compared.

Examples & Applications

Case Studies and Practical Uses

Applied sciences include fields like medical microbiology and other aspects of the medical sciences. It is in these fields that biology is used to medical knowledge and innovations, although it is not always in biomedicine or biomedical engineering, which is more explicitly developed. Probability theory and statistical analysis are used in epidemiology to analyze the patterns that emerge from a population's health and disease. The field of genetic epidemiology is an applied field of study that makes use of both biological and statistical techniques.
