Study Is Challenging: Why Physics Is the Uttermost Hated Subject by Students

Physics is one of the oldest elementary sciences. It is the expert learning subject for the study of matter, energy, time and space, velocity, etc., and it also explores in-depth knowledge about the interactions between these elements. Its objective is to know the universe and understand the different phenomena that

Particle Frenzy: Poem

It began with a bang. At high energies the universe sang. Born were time and particles many; Perfect symmetry, there was complete harmony. What we see now is complete mystery, How is there a broken symmetry? Matter-antimatter, how does it matter? Matter/antimatter, which does it favor? Well…all that

Stigma: A Science Fiction Story

The laboratory seemed long deserted. No vital sign of breath. Somehow, at the secret underground part, there was something going on. Insignificant stage of a significant mission. And there he was, Dr. Hue, standing in front of a huge machine in the shape of a metallic ring. This machine, was

Einstein, the War and General Relativity

Einstein’s theory of General Relativity is one of the greatest exercise of human thought. For, those of us, who have had the good fortune to study it in detail, we cannot stop wondering in awe at the beauty of the theory. Though, built with techniques of abstract and abstruse

Cube of Nature: Evolution of physics and mathematics

“Mathematics is the mirror of civilization” Physics deals with the study and understanding of the physical world. And simultaneous study and measurement of experiment and mathematics lead us to the fundamental understanding of nature. Mathematics is the language of physics, and hence considered as the universal language to understand our

Gravitational Waves

The activities of the universe are truly mysterious. In its folds lie the knowledge of the past, the present and the course of the future. Science has always endeavored to unfold the true nature of our universe, and yet after centuries of human evolution we are to some extent unsuccessful

Simulating the Atomic World

Computer simulation, in the present day scientific scenario, has become one of the primary tools in both basic and applied sciences. With the escalating advancement of science in the last few decades experiments have become more complex with the use of sophisticated scientific instruments. And understanding such complex scientific phenomena

Life cycle of Stars

Sun, the brightest object of our solar system, is the primary energy source of our life, in fact for any living organism. Sun is considered to be the central object of our solar system that holds all the planets and their moons together. The day begins with beautiful sunshine and

On the Nature of Light

It is the fastest in the universe and has to be fast since nothing can even reach its speed. Light or adustum as it is known in Latin is the ultimate form of energy. It is not just about the visible wavelengths but even more about numerous others that sustain

Higgs Boson: The Nobel Winning Particle

Nobel Prize, the most prestigious honor awarded to physicists in his life time for outstanding contribution to physics. In 2013, Nobel Prize in Physics has been awarded to physicist Peter Higgs along with F. Englert for their contribution of Higgs Boson, the particle which is supposed to give mass to

God Particle: “If Universe is the answer what is the question…??”

The whole conversation starts with Higgs Boson. If you are from non-physics background then just think it is a hypothetical sub-atomic particle with extremely negligible life span. It exists for a mere fraction of second. The specialty of Higgs boson particle is that it is considered to be the origin

Quantum Yang-Mills Theory

[Editor: This is next part in our series of articles on the Millennium Problems.] In classical physics, there were two kinds of entities, material particles governed by Newtonian mechanics and fields governed by appropriate field equations eg Maxwell’s equations for electromagnetic field. However just before and after the beginning

Time Dilation and Relativity

Of all that we have known in physics, the Galilean laws, the Newtonian laws, the discovery of the speed of light along with many others govern the mind. In the eyes of Physics, in the 20th century physics the very concept of Relativity was a Renaissance. Relativity can be said

The Dark Fantasy

There seems to be a HALO of mysterious invisible material engulfing galaxies, which is commonly referred to as Dark matter. Scientists infer the existence of dark (=invisible!!!) matter from the observation of its gravitational pull, which causes the stars in the outer regions of a galaxy to orbit faster than

Invisibility

Invisibility tends to reality

Can invisibility be reality? A query which has been in the back of curious minds of the scientific giants and even the common masses throughout many generations, has finally found a positive answer and the credit for it unquestionably goes to science and particularly to physics.
