Question 3:
Explain what the reasons for the following are.
(i) Einstein leaving the school in Munich for good.
Answer: Albert Einstein was not a bad pupil. He scored good marks in almost every subject. However, he hated the regimentation of school, because of which he often had clashes with his teachers. At the age of 15, when he felt too stifled to continue studying, he left the school in Munich for good.
(ii) Einstein wanting to study in Switzerland rather than in Munich.
Answer: According to Einstein, German-speaking Switzerland was more liberal than Munich. Hence, he wanted to study in Switzerland.
(iii) Einstein seeing in Mileva an ally.
Answer: Einstein had a special interest in Mileva, who was his fellow student. He thought that she was a very clever person. She had come to Switzerland because the University in Zurich was one of the few in Europe where women could get degrees. Einstein instantly realised that she was an ally against all the people he was at odds with. He thought she was a clever person.
(iv) What do these tell you about Einstein?
Answer: All these instances indicate that Einstein was a visionary. He was clever and never hesitated in keeping his point of view in front of others. He never went with the tide and did things the way he wanted to. Once he knew that he was right, he was not afraid of being at odds with his teachers or for that matter anyone else.
Even though he was doing well in school, he left it because he found it too stifling. He eventually moved to Zurich because he thought that this city was much more liberal than Munich. He liked to mix with people who had the same attitude as him. He was a strong man who stuck to his principles and ideas and was not afraid of bringing them into practice.

Question 4: What did Einstein call his desk drawer at the patent office? Why?
Answer: Einstein was working as a technical expert in the patent office in Bern. He called his desk drawer at the patent office the “bureau of theoretical physics.”
He called it so because while he was supposed to be assessing other people’s inventions, he was actually developing his own ideas in secret and his drawer was where he stored these ideas.
Question 5: Why did Einstein write a letter to Franklin Roosevelt?
Answer: When the Nazis came to power in Germany, Einstein emigrated to the United States of America. The American physicists were in an uproar because of the discovery of nuclear fission in Berlin.
They were afraid that the Nazis could now build and use an atomic bomb. At the urging of a colleague, Einstein wrote a letter to Franklin Roosevelt to warn him of the consequences of an atomic explosion.
Question 6: How did Einstein react to the bombing of Hiroshima and Nagasaki?
Answer: The Americans developed the atomic bomb in a secret project and dropped it on the Japanese cities of Hiroshima and Nagasaki. Einstein was deeply shaken by the extent of the destruction caused by the explosions.
He proposed the formation of a world government. However, his proposal was not paid any attention. Over the next decade, he got more involved in politics, trying to agitate people to bring an end to the arms race. He campaigned for peace and democracy till his last days
Question 7: Why does the world remember Einstein as a “world citizen”?
Answer: The world remembers Einstein as a “world citizen” because he was a visionary and a scientific genius.
He not only made many discoveries in science but was also deeply concerned about the growing arms race between certain nations in the world. He used his popularity to campaign for peace and democracy till his last days.
