Einstein, in his famous equation E=mc2 (energy equals mass times the speed of light squared), says that mass is energy and energy is mass. This is correct only if we see first the mass and then the energy, not the other way around. Differently said, energy doesn’t exist without mass, but mass without energy does. The existence of energy depends on the mass. No mass, no energy. The equation should have been written M=ec2 (mass equals energy times the speed of light squared) and no viceversa. Now, time, space and energy don’t exist, if so, what is left of Einstein’s special and general relativity?

The questions about space, time, energy and special or general relativity don’t end here. Einstein almost silenced Newton's gravity and in its place placed Maxwell's electromagnetism and his space-time. The Earth no longer revolves around the Sun, like in the old days, but it shoots straight ahead. The theory of general relativity imposes this concept. Let’s suppose now for an instant that the Sun is no longer there, what will happen to the Earth? Will it continue to go around and around even without the Sun or it will start darting into deep space?

If an electron of charge -e and mass m or positron of charge +e and mass m is to assume any configuration, it is most likely to be an impenetrable spherical shell of radius a with a uniform surface charge. The electric potential is constant and the electric field is zero inside the shell. From outside the shell it is as if the whole charge is concentrated at the centre of the sphere. The radial electric field outside the shell, in accordance with Coulomb’s inverse-square law, pulls the surface charge outwards while the universal space pushes it inwards to maintain a stable structure, like a bubble in the air. Such a configuration should have intrinsic energy E_n and mass m, where E_n = ½mc², c being the speed of light in a vacuum.  A positron and an electron join together to form a neutral particle called “unitron” of intrinsic energy 2E_n, potential energy -E_n  and mass m. The positron, the electron and the “unitron” are proposed as the basic constituent particles of matter. On this premise, two models of the hydrogen atom are developed, a non-nuclear model identified for the gaseous state and a nuclear model for the liquid or solid state, with emission of radiation at frequencies in conformity with the Balmer-Rydberg formula. The hydrogen atom is the building block of atoms of elements and molecules of compounds.

As Michael Faraday came up with electromagnetic field in the 19^th century to Maxwell’s equation in 1862 to Max Planck’s blackbody radiation to Albert Einstein’s photoelectric effect in 1905 and Niels Bohr’s bohr model in 1913, electron has been key element that plays core role in formulating physics phenomena.Spintronics, which is the study of spin of electrons in hard solid devices such as semiconductor, is believed to be crucial field regarding engagement of electromagnetic works in spaces at material appliances around us that can promote people’s quality of lives.Therefore, I decided to present my view with combined structures of both QFT and Spintronics that entails electrons movements into practical formula as well as opening possibilities to biophysics that can greatly contribute to our lifecycle and wellbeing.Entire works of mine are based on my self-learning started with a book called ‘Basic Physics’ written by Karl F.Kuhn and self-paced learning online.
