Systems theory is the complex interdisciplinary study of every type of phenomena occurring in this world. It takes into account different properties such as substance and type of phenomena. Systems theory also employs effective mathematical models to better describe the details involved.
First proposed by biologist Ludwig Von Bertalanffy, it was evolved further by Ross Ashby. Unifying science was the underlying principle of the systems theory. It attempts to disprove the need to independently study various scientific fields such as physics, chemistry, biology, technology, etc. It states that the complete understanding of the working of a body can only be achieved by looking at the relationships between all the parts that constitute it. This means combining all the fields of science under one roof. Systems theory involves a holistic approach, studying the interaction between a body and its surroundings. Particles, cells, and molecules can be defined by different sciences. But looking into their working with other particles, cells and molecules gives us a clear picture of the entire system. Systems theory helps in analyzing effectively and dealing with various problems. Identifying problems and constructing solutions becomes much easier with a complete understanding of a process and its internal workings. While expertise calls for diversification of science, systems theory tries to reverse that aim.
