Ans. Although as a young child, Einstein was very slow, still while studying in Munich, he showed great progress in almost all the subjects and scored very good marks. He showed a special interest in Physics and Mathematics.
Q.29. Why did Einstein leave school in Munich?
Ans. Einstein left the school in Munich because of the stifling environment that suppressed his scientifically curious mind. The excessively stern discipline and rigid rules in that school led to frequent clashes with his teachers. He thus began to feel that such a place was inappropriate for a liberal person like him.
Q.30. Why did Einstein shift to Switzerland to continue his education?
Ans. Einstein shifted to the German-speaking part of Switzerland to continue his education because he had left his school in Munich midway. This new place was more liberal than Munich and Einstein’s curious and free temperament got a favourable environment over here.

Ans. Einstein jokingly called his desk drawer at the patent office as “Bureau of theoretical physics”. He did so because his office job required him to assess the inventions of other people while he secretly developed his own ideas regarding his keen interest in Physics.
Q.33. Why did Einstein’s mother does not want him to marry Mileva?
Ans. There were two reasons for Einstein’s mother not wanting him to marry Mileva. Firstly, the girl was three years older than Einstein and secondly, she was much too intelligent – ‘a book’ just like him, in his mother’s opinion.

Q.36. When and for what did Einstein gain international fame?
Ans. Einstein gained international fame when his paper on General Theory of Relativity was found to be accurate in 1919. As per this theory, the calculations made by Einstein in advance about the deflection of light in the solar gravitational field during the eclipse were proven true. This theory was treated as “a scientific revolution.”
Q.37. How was Einstein honoured for his achievements?
Ans. Honours came pouring in for Einstein after his theories proved him to be a scientist with exceptional abilities. He was awarded the prestigious Nobel Prize for Physics in 1921. Honours and invitations were conferred on him from all over the world. The newspapers too applauded his genius.
Q.38. Why did Einstein leave Germany and emigrate to America?
Ans. Einstein had always been a lover of freedom and liberal ideas. The Nazi government, which came to power in 1933, was very suppressive and autocratic. Therefore, Einstein left Germany and emigrated to America.

Q.41. What was the effect of Einstein’s letter on Roosevelt?
Ans. The warning sounded by Einstein in his letter to Franklin D. Roosevelt about how dangerous an atom bomb made by German)’ could be, had a lightening effect on the Americans. They at once rose to action and secretly developed an atom bomb of their own.
