Significance of Physics in Engineering Education

'All truths are easy to understand once they are discovered; the point is to discover them. - Galileo Galilei'
Physics deals with study of natural phenomenon, processes, laws, principles that are observed in nature. Galileo Galilei called as “father of modern physics”, “father of observational astronomy” was first of modern scientists who affirmed that laws of nature are mathematical. Galileo was referred as “father of modern science” by Albert Einstein for his remarkable work in physics and allied fields of science.


Now a day, study of Physics can be classified in to two broad areas which are Classical Physics and Modern Physics. Classical Physics deals with macroscopic study of Newtonian mechanics, the concept of gravitation and Langragian Formulation. On the other hand, concepts of modern Physics are applied at microscopic levels in the field of quantum mechanics, solid state physics, nuclear physics, theory of relativity, quantum thermodynamics etc.

Physics provides guidelines to solve the engineering and technology related problems in a simple manner. The solution to these problems requires imagination and application of knowledge. Engineering Physics uses basic concepts of Physics to develop new technologies and find solutions to everyday engineering problems.

Professionals in the field of Physics usually apply their knowledge and skills to various engineering disciplines like manufacturing, material engineering, electronics, electrical, computer, medicine and biotechnology etc. The drastic changes in the properties of material on Nano-scale have opened up a new dimension in sensor technology, environmental studies and energy. The interesting ideas thoroughly studied in Physics at various levels are as follows.

  • Wave Particle Duality
  • Einstein's Theory of Relativity
  • Quantum Probability & the Measurement Problem
  • Heisenberg Uncertainty Principle
  • Quantum Entanglement & Non-locality
  • Unified Field Theory
  • The Big Bang Theory
  • Dark Matter & Dark Energy

The learning in Physics departments at college and university level focuses on the experiments that are of current research interest in day to day life while engineering physics focuses on things that are of use in the development and design of new systems.



Some of the remarkable inventions that changed the scientific world are worth mentioning includes:

  • Origin of Universe
  • Waves carry energy.
  • Quantum Mechanics
  • Special Theory of Relativity
  • The concept of superconductivity and its applications
  • The use of Lasers for peaceful and industrial applications.
  • Semiconductor devices
  • Nanotechnology
  • Gravitational Waves

Physicists are researching to enhance the scientific understandings that can be used for transformation of knowledge for the technology updates useful for human beings. They are curious to know basics of Nano science that plays vital role in overall development of science and technology.

Multidisciplinary approach in education and future work environment involves integration of different disciplines and different perspectives. Engineering physics, also referred as applied physics is the strongest pillar in integrating different disciplines as physics is one of the most fundamental scientific discipline. Engineering education at JNEC is focusing on implementing multidisciplinary approach through pedagogy and project based learning. Physics is playing important role in developing complex problem solving skills of students by enriching the students with sound knowledge of physical concepts and principles.

Engineering programs such as mechanical engineering, civil engineering, electrical or electronics engineering and information technology involves fundamental understanding of physics. Most of the technological development related to above mentioned engineering branches are based on physics. Applied science department of JNEC, instituted for study of applied sciences by first year engineering students, is well equipped with laboratories for conducting the experiments. Innovative pedagogy, modern assessment processes and research-driven teaching staff is contributing to build strong foundation of engineering physics knowledge so as to help engineering graduates in solving real life engineering problems.
