The Full Form of PCME is‍ Physics,Chemistry,Mathematics and Electronics.

Physics

The Department of Physics in CHRIST (Deemed to be University) was started in the year 1969. It offers Physics as a subject at the undergraduate and postgraduate levels. It offers two specializations i.e., Crystal Physics and Electronics at the PG level. The course opens up teaching as well as research opportunities in Physics. The postgraduate course in Physics is the final formal training for students to provide in depth knowledge of the subject. Hence, regular class room teaching is supplemented with tutorials, brain storming ideas and problem solving efforts pertaining to each theory and practical course.

Mathematics
The undergraduate course in Mathematics is designed to enable the students to lay a strong foundation in various fields of Mathematics. The course enables the students to develop a respectable intellectual level seeking to expose the various concepts in Mathematics. It also aims at enhancing the students reasoning, analytical and problem solving skills. The first four semesters are devoted to appreciate the beauty of mathematics through Introductory Algebra, Calculus, Differential Equations and Calculus of several variables. In order to help the students in exploration of mathematical concepts through activities and exploration, FOSS(Free and Open Source Software) tools like SCILAB and MAXIMA are introduced.Students find better perceptions of the classical papers like Abstract Algebra, Linear Algebra and Real and Complex Analysis in final year. Numerical Analysis, Fourier series and Integral Transforms  papers help the students to envisage an in depth knowledge of various numerical methods and integral transforms required in Scientific and Technological  Applications.

Electronics
The department aims at setting a benchmark in education in the field of electronics by incorporating new and innovative teaching methods which include learning management system (LMS) Moodle, MOOC, software simulators, video presentations, projects, internship etc.. The undergraduate programme is diversified greatly in order to keep in pace with recent trends and developments and the fast changing needs of the society. The three years of study starts from the fundamentals of electronics, semiconductor devices and applications, Linear integrated circuits and applications, digital logic design and VHDL, Analog and digital communication systems, satellite communication, fiber optic communication, microcontrollers and embedded systems, electronic instrumentation, industrial electronics , digital signal processing etc.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
