1919 by an eclipse of the sun which Einstein had previously calculated about
the extent to which the light from the fixed stars would be deflected through
the sun’s gravitational field.

After it was proved correct,
the newspapers proclaimed his work as “a scientific revolution”. Moreover, he
received Nobel Prize for physics.

 

15. Why did Einstein leave Germany? What

mathematics and interested in physics. After that, he got admitted to a University in Zurich.

 

 

2.    How
was the relation of Einstein, his mother and Meva Maric?

Ans. Einstein had a
great interest in subjects like mathematics and physics. Apart from these, he had

to be a “clever creature”. She was three years older than Albert. Einstein saw an
ally against the “Philistines” with those people with whom he was constantly at
odds. They fell in love with each other. They wrote letters for each other
mixing science with tenderness. While Einstein was solving the most difficult
problems in physics, his private life was unravelling. He wanted to marry
Mileva after finishing his studies but his mother was against of hid marriage
with Mileva. She was also bothered by Mileva’s intelligence. But they finally
got married in the year of 1903 and had two sons. Later on, they got divorced

ambition.



 

3.    Discuss
Special Theory of Relativity and General Theory of Relativity.

Theory of Relativity provided a new interpretation of gravity. It was published
in the year of 1915. According to this theory, time and distance were not
absolute. His theory was proved in the year of 1919. Einstein had properly
calculated the extent to which the light from the fixed stars would be
deflected through the gravitational field produced by the sun beforehand. The
newspapers proclaimed his work as a “scientific revolution”.

 

4.    What
was Einstein’s take on Atom Bomb? How was it a part of his whole life?

Ans.
After the Nagasaki and Hiroshima incident that occurred in August, 1945,
Einstein was deeply shaken by the extent of the destruction. He wrote a public
