Einstein was not only the scientist who brought ‘a scientific revolution’ but also a gifted amateur violinist and political thinker. Unlike other children, he started speaking after the age of two-and-a-half. He uttered the first sentence when one night, he broke his silence to say, “The soup is too hot.” His prodigious penchant towards mechanical toys was revealed when he looked at his newborn sister, Maja, and said: “Fine, but where are her wheels?” Einstein’s ‘Special Theory of Relativity’, which states that time and distance are not absolute, was a ground-breaking finding. His General Theory of Relativity, published in 1915, provided a new interpretation of gravity. An eclipse of the sun in 1919 proved that the theory was accurate. Einstein had correctly calculated in advance the extent to which the light from fixed stars would be deflected through the sun’s gravitational field. The newspapers proclaimed his work as “a scientific revolution.” Einstein received the Nobel Prize for Physics in 1921. He also expressed his concern to Franklin D Roosevelt against the atom bomb. He had also written to United Nations to form a world government to conserve peace and democracy in the world. Hence, Einstein is certainly a synonym for genius

The disciple did not want to leave the palace because the most important thing in life for him was food. And in the kingdom of fools, food was very cheap and good. The disciple therefore, stays back in the kingdom, refusing to listen to his guru word. It eventually turned out to be a very foolish idea because he eats without a respite and begins to resemble to resemble a street sidw overfed sacred bull
