In the present scenario of professional education aimed to get easy and good employment opportunities, many-2 new educational subjects have made their way to people’s choice.  Any educational subject has a meaningful existence when it is pursued by many people for higher learning. There were times when core subjects like Physics, Chemistry, and Mathematics were the craze as challenging subjects for brilliant minds.

Students were not only motivated to opt these subjects in high education level due to job opportunities but also to some extent to learn more about nature and its working all around us.  It never means that other core subjects like history, social sciences, languages (English etc) were not the desired choices of the students.  Other subjects were equally pursued by students but the students studying subjects like Physics, Chemistry, and Mathematics were drawing due respect in the society. Presently, however, much have changed about the selection and pursuing of higher education subjects. At technical level also many subjects have lost boundaries and have mixed in each other.

Physics like other subjects is one of the main subjects which make people to think something new about nature however many few people are pursuing Physics as a subject of higher learning. Physics has and will always motivate and attract intriguing minds towards its beauty as a subject. When we call physical laws “beautiful,” we mean primarily two things: they are wonderfully symmetric and wonderfully productive. And the beauty of the laws has lately become more important than ever to scientific progress. In this article, an effort has been made to highlight the beauty of Physics as a subject. Though, the presentation in any means does not undermine the importance of other subjects. Physics is the fundamental science branching into narrow pathways leading scientific discovery of the unimaginable, the unexpected, the exciting and electrifying. Physics is all about imagination and curiosity. It is about bringing together tiny bits of thoughts to come up with something meaningful. The soul of the science remains to remove ambiguity and establish facts! It does what almost every science does, gives us proof which serves as an answer to our question.

Physics is the search for and applications of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems. Physics is not a subject related to abstract, data and its interpretations or just to read and memorized the past and present facts but it is something by which anything can be reasoned. We can conceive the idea and follow the development of idea by understanding every step. These different ideas cumulate as technology or engineering products for the benefit of mankind. Physics makes a reader to question and answer amazing things of nature happening all around him like Dark energy, Black holes, supersymmetries etc. There is also something beautiful about simpler physics: a moving charge creates a magnetic field, length shortens when speed increases. The source of beauty in the laws of physics is their productivity. Just a handful of basic principles generate an astonishing wealth of consequences – everything in the physical world. Wishful thinking could never have produce working iPhones, photographs of Pluto, or atomic bombs, developments in computer power, virtual reality, and artificial intelligence but it is due to the basic knowledge provided by Physics. Physics, as summarized in a handful of mathematically precise laws, indisputably works. Yet many things that “work” do not inspire the kind of admiration that the fundamental laws of nature do. Great Physicists have just quoted about beauty of physics and similar sentiments are all but universal among modern physicists.

  • The nineteenth-century physicist Heinrich Hertz once described his feeling that James Clerk Maxwell’s equations, which depict the fundamentals of electricity and magnetism, have an independent existence and an intelligence of their own, that they are wiser…even than their discoverers, that we get more out of them than was originally put into them.
  • Albert Einstein called Niels Bohr’s atomic model “the highest form of musicality in the sphere of thought.”
  • The late Nobel laureate Richard Feynman, describing his discovery of new laws of physics, declared, “You can recognize truth by its beauty and simplicity.”
  • Melvin Schwartz-The beauty of physics lies in the extent which seemingly complex and unrelated phenomena can be explained and correlated through a high level of abstraction by a set of laws which are amazing in their simplicity.

The beauty of physical law is too impressive to be accidental. It has led people throughout history to believe that some tasteful higher being created us, and that we inhabit a consciously designed world. But this is an extravagant hypothesis, which goes far beyond the facts it is meant to explain.  The evolutionary utility of the beauty of physical laws is somewhat less obvious, but no less real. Given the usefulness of accurately assessing the consequences of our actions, our reward system has evolved so that we derive joy from making successful predictions. Understanding the forces and patterns defining our world, and especially principles that apply (without changing) to a wide variety of situations, can help to improve our predictions. The fact that we can often infer the behavior of complex objects or systems from knowledge of their parts – that we get back more than we put in – can help us to hone our predictions further.

When it comes loving a subject we can love it for the results we get from it, or we can love it for the process of doing it. Beauty of Physics is reading textbooks and articles, solving problems, doing calculations, experimenting, etc. Though, learning physics and solving problems is not that easy going job however it is still interesting and immensely rewarding. The dictionary definition of physics is “the study of matter, energy, and the interaction between them”, but what that really means is that physics is about asking fundamental questions and trying to answer them by observing and experimenting.  Physics doesn’t just deal with theoretical concepts. It’s applied in every sphere of human activity, including:

  • >Development of sustainable forms of energy production
  • >Treating cancer, through radiotherapy, and diagnosing illness through various types of imaging, all based on physics.
  • >Developing computer games
  • >Design and manufacture of sports equipment
  • >Understanding and predicting earthquakes

In fact, pretty much every sector we can think of needs people with physics knowledge and equip a physicist with following qualities:

  • >Physics helps to develop critical thinking and problem-solving skills.
  • >Physics so many phenomena, is so fundamental, is a beautiful and elegant theory, has intriguing concepts and problems, etc, etc.
  • >Physics makes things possible.
  • >Physics makes you more attractive to recruiters/employers
