GRAVITATIONAL WAVES Concept of gravitional waves according to Einstein Well Einstein was a man wuth great mind, he had put forth many jaw-dropping laws and relations which jad just changed the way of looking at the physics as in the case of gravitional waves. A concept which descripes how space time fabric bends around the large celestial accelerating objects for instance, in the case of two black holes colliding,they had a great acceleration and their collision could led to one of the most fascinating phenonmena of the mysterious gamma ray bursts which too are so energetic ,this could be explained by using the plack's idea of quantization and relation of that energy with the frequency of the EM radiation, in case gamma rays (not waves as waves do have a particle nature) and this energetic revolovment and motion would led to the formation of ripples in the space time fabric.
ANURAG SAMBHRIYA MODELS OF ATOM Thomson's model of an atom Thomson was a greater mentor and taught upto 7 person who have got noble prize incorporating rutherford who had disproven his model. His model is also called the plum pudding and watetmelon model of an atom as he had proposed that atlm is some sort of spherical ball onto which most of the posit ive charge is spread uniformly (just like the milk in the plum pudding and fleshy part in the watermelon)and negative charged electrons are embedded over it (just like the currents in the puddung and seeds in the watermelon )
