Learning Physics helps us to understand how the world around us works. The knowledge of Physics is the very basis for most modern technology and studying Physics strengthens quantitative reasoning and problem solving skills that are valuable in areas beyond Physics. Majoring in Physics provides the graduate student the excellent career platform to train the mind in all branches of engineering and information/computer science disciplines. It is also useful to pursue interdisciplinary programs in life sciences, earth sciences, atmospheric sciences and even in economics public policy and journalism. All the College and corporate recruiters recognize the value of analytical brains developed through Physics.

Physics at National College gives a student a transformational experience by virtue of its legacy in the College and well-knit curriculum. The Department of Physics is one of the oldest in the college and is functioning from the prestigious Science Block. It provides a conducive learning environment for the students to develop scientific insights and practical skills in order to apply them for solving real world problems.

The Department regularly arranges workshops, national and international conferences. Students are imparted leadership training through the Physics Association activities. Also, they are highly encouraged to enroll themselves in any one of the co-curricular and club activities in the campus and are sent to the competitions being held in the other Colleges and Universities.

At present, the Department’s faculty strength is 20 (Aided-13, UAP-7) with three non-teaching staff assisting them in the laboratories. The faculty are highly qualified and are involved in both teaching and research. Research grants have been received from the Central and State Government agencies viz. UGC, DRDO, DST, CSIR, DBT and TNSCST. The Department is recognized as one of the STAR Departments in the College under DBT scheme.

In addition to the Core Physics programs, the Department, regularly offers allied and elective Physics courses to the students of other science Departments in the College, especially to those in Chemistry, Mathematics and Geology.

The alumni of the Department are well placed in diverse areas including premier research and educational institutions, public, banking and private sectors. The Department celebrated its Golden Jubilee in 2009 and Diamond Jubilee in 2019. The Department happily welcomes all those students who intend to achieve success in the world with Physics as a means.
