Albert Einstein was one of the greatest scientists ever born on this planet.
He is famous for his work in the field of astrophysics, especially for his theory of Gneral , Special relativity including photoelectric effect, mass energy equivalence formula etc.
In the early stages of his life he was a struggler. His days of school and collage weren't that good. His professors didn't liked him much.
During his studies he fell in love with one of the students names Mileva Maric.
They relationship didn't worked well but he had a child even before his marriage who later died.
After 2 years of thier child's death they married but that didn't worked too.
They faced a lot of economic problems and Einstein had to join a patent office as a Clerk in Sweden.
And this was the time when he add access to all important papers. He ised to call his desk " Bureau of theoretical physics". In 1905 he pointed out the whole idea of Ether as unnessary which was prevalent at that time. And he was willing to abandon the Idea of absolute time.
Einstein's arguments were closer to the French mathematician Henri poincare exept for the part where the mathematician regarded that problem as purely mathematical.

Einsteinin 1905 presented a theory called as Special relativity. It had 2 postulates one that laws of physics should be same for all freely moving observers no matter what their speed is. And the second one was all freely moving onservers must measure the speed of light as same no matter how fast they are moving towards or away from the source.
His arguments about gravity were different from newton and were more accurate. They perfectly matched the observations. As in the case of planet mercury. Suppose that suddenly the sun disappers then According to newtonian Gravity well know that immidiately as the earth with leave it's orbit as a result of no more gravitational force on it. But Maxwell's theory (supported by Einstein) predicted that we'll know that after about 8 minutes as the light will continue to come from there till then.

Between 1908 and 1914 he made a lot of unsuccessful attempts to find a theory of gravity that was consistent with relativity.
But finally in 1915 he proposes a brand new theory called "General theory of relativity".

He explained that space was not actually falt but curve. It bends when massive objects are kept on the fabric of Space time.
And according him Space and time weren't 2 different thing but were something same and hence called Space-time.
He once said "One can't help but be in the awe when one contemplates the mystery of eternity of life, of marvellous structure lf reality and mystery of it".

He famous equation e=m^2 the mass energy equivalence formula said that mass and energy are same thing.
On the basis of which atom bomb was created.
And Einstein was very regretfully that it was his thoery that lead to destruction in Nagasaki.
In the later couse of his life he finally broke away from Meliva and married his cousin Elsa Lowenthal.
He was then a professor in Berlin, Gremany and was aginst the World war.
Anti organiaations were set up in Germany as it was the time lf hitler who hated jews and Einstein was a jew. His theories were criticised.
He left Germany and went to America.
He got involed in politics because of the the nuclear attack.
His life was "divided between politics and equations" in his own words. Throughout his life, he made his efforts towards peace.
He quotes that " Equations are more important to me, because politics is for present, but am equation is something for eternity".

He always support the idea of having imagination better than knowledge.
