Pure sciences involve the study of natural phenomena to understand them and develop scientific theories to explain them without consideration of their application. It includes a method of investigating nature by the experimental method in an attempt to satisfy the need to know. Physics, Chemistry, Biology and Astronomy are all pure sciences.
The focus of pure sciences is on developing theories, laws and principles that explain the natural phenomena in world and the universe around us. Applied science on the other hand focuses on solving a specific problems or creating a product. Pure science generates better tools for applied science to use in solving problems. When there is a problem in applied science that current tools of science can’t solve, it becomes a new area for pure scientists to investigate.
Admission to pure science courses is based on class XII marks in most universities across the country. However, some of the established institutions such as IITs, BITS, IISc, NISERs, to name a few, either use the scores of entrance exams such as JEE Mains and JEE Advanced for granting admission or have their own entrance exams such as BITSAT and NEST
With an increase in the number of Indian students wanting to study pure Sciences, a number of universities and colleges have begun offering undergraduate and post graduate courses in pure sciences. In addition to give thrust to high quality education and research in pure sciences the Government of India has set up the Indian Institutes of Science Education and Research (IISERs) at Bhopal, Kolkata, Mohali, Pune and Thiruvananthapuram and the National Institute of Science Education and Research (NISER) at Bhubaneshwar, which offer a 5 year integrated programme in pure sciences. In addition pure science programs are there at the IITs BITS (Pilani, Goa and Hyderabad) and the Indian Institute of Science (IISc), Bangalore.
There are a number of job opportunities for a pure science graduate nowadays if he/she is equipped with proper type of training pertaining to his branch because of globalisation that has resulted in many MNCs in coming to India and utilising the potential for research here. In addition the growth of the education sector has also created a demand for qualified teachers. Moreover apart from the traditional pharmaceutical, fine chemical and the automotive sectors which were big employers of science graduates, now there is a broader interest across many sectors — from machine tools and cement to electronics and healthcare.
Salary of a scientist depends largely upon their academic qualification, institute or university from which the degree is attained and the level of work experience they have achieved. To start with the budding scientists from prestigious institutes like IITs, IISc etc can get anything between Rs.2,00,000 to Rs.3,00,000 as annual income in the private sector and this goes up several times with experience. Salaries in the government jobs tend to be lower.
