The discovery of the ionization of gases by ultra-violet light was made by Philipp Lenard in 1900. As the effect was produced across several centimeters of air and made very great positive and small negative ions, it was natural to interpret the phenomenon, as did J. J. Thomson, as a Hertz effect upon the solid … Continue reading PHOTO-ELECTRIC. A NOBEL AWARD ARTICLE 
In the X-ray regime, the photoelectric effect in crystalline material is often decomposed into three steps: 1)Inner photoelectric effect . The hole left behind can give rise to auger effect, which is visible even when the electron does not leave the material. In molecular solids phonons are excited in this step and may be visible as … Continue reading Three-step model(PHOTOELCTRIC EFFECT)
A neutrino electrically neutral, weakly interacting elementary subatomic particle with half-integer spin. The neutrino (meaning "small neutral one" in Italian) is denoted by the Greek letter ν (nu). All evidence suggests that neutrinos have mass but that their mass is tiny even by the standards of subatomic particles. Their mass has never been measured accurately. … Continue reading Neutrino – What is it?
The unification of forces is possible due to the energy scale dependence of force coupling parameters in quantum field theory called renormalization group running, which allows parameters with vastly different values at usual energies to converge to a single value at a much higher energy scale.It is commonly believed that this matching is unlikely to … Continue reading important role of supersymmetry in Unification of forces (grand unified theory)
i never tried these equations untill i make my own mathematical approaches to the level of mathematical physics.i never suggest readers of my blog to not read einstiens field equations,the field equations needs higher mathematics...guys once think about the photoelectric effect ,that was greatest discovery which einstien got nobel prize,but now school childrens learn that … Continue reading The Einstein field equations (EFE)
is gravitational singularity and space time singularity are same?simple its same,guys the time and space sometimes makes an whirlpool like pattern(i personaly understand like this) this patern is no longer uniform,it may be a swirl type or water pool type,it may be affected by mass.how singularity works?what is singularity?A gravitational singularity or spacetime singularity is … Continue reading Gravitational singularity(simple way understanding)
the idea behind this worm hole is given by albert einstien.when einstien publishes his general theory of relativity,it contains the space-time,gravity-time wrap,gravity curve.etc.A wormhole, also known as an Einstein–Rosen bridge,is a hypothetical topological feature of spacetime that would be fundamentally a "shortcut" through spacetime. A wormhole is much like a tunnel with two ends each … Continue reading worm hole (short cut to space time)
