Physics Department

Department of Physics is one of the right places in our college for understanding basic science.  The present department is a recognized research Centre from Vishweshvaraya Technological University (VTU), Belagavi where intense research is being taken place in the field of Quantum dots, Nanotechnology, Solar cells, Materials Science - Magnetic Materials, Magneto caloric Materials, Ceramics etc.

The department is equipped with well qualified teaching as well as research faculties and supporting staffs.  Also, it includes fully-fledged laboratories and advanced experimental setups for students to realize concepts in Physics. 

The overall agenda of the syllabus incorporated in the engineering physics is to expose the students to very important basic concepts related to the advanced technology available today around the globe.  The list of experiments included in the curriculum are totally related to the classroom theory-syllabus.  Therefore, the detailed discussions made in the classroom about the theory would be realized while conducting related experiments back in the laboratory.  In this process students would gain deeper knowledge of fundamental governing principles based on which the present day advanced engineering technologies are build.

To impart the quality education in the process of understanding fundamentals based on which the present or future technology is established. Exposing students to new and important basic concepts in physics to develop ability in them to solve complex engineering problems.

The department is with a proposal of starting master degree in Physics in the near future timeline. Also, up gradation of advanced experimental facilities to conduct frontline research for invention and innovation is the higher priority.

Department of Phyiscs has started publishing a periodic science magazine "VIGNYAN".

The first volume (part 1) of the same on "Quantum Physics and Quantum computation" has been released by the Vice-chairman and other dignitaries on january  26th - Republic day function 2020.

     

---------------------------------------------------------------------------------------------------------

Department of Physics organized many training programs in various Districts in Karnataka for high school teachers to enhance their quality in understanding and teaching Science subjects to students.  Practical sessions were also conducted in the physics department laboratory, MCE, Hassan. These sessions were dedicated to demonstrate the fundamental science concepts related to High School syllabus to all the participants.  In this process many school students from Hassan Taluk were also benefited by visiting the same exhibition.  The department was successful in integrating other branches like Automobile Engineering, Mechanical Engineering, Electrical & Electronics Engineering, Electrical & communication engineering of Malnad Engineering College, for the same workshop to benefit the high school teachers for clarifying their doubts from field experts.  This work shop was sponsored by TEQUIP and held thrice in Hassan (TQ), once in Chikmangalore (D), Shivamogga(D) and Mandya(D).
