Question 3.
Explain what the reasons for the following are:

Einstein leaving the school in Munich for good.
Einstein wanting to study in Switzerland rather than in Munich.
Einstein seeing in Mileva an ally.
What do these tell you about Einstein?

Answers:

Einstein left the school in Munich because he did not like the discipline of the school. He hated the school’s regimentation and often clashed with teachers.
Albert’s parents moved to Milan and left their son with relatives. After prolonged discussion, Einstein got his wish to continue his education in German – speaking Switzerland. Actually, it was more liberal than Munich.
Einstein saw in Mileva Marie an ally against the “Philistines”—those people in his family and at the university with whom he was constantly at odds. He found that she was a “clever creature”.
These tell that Einstein was a genius and had the capabilities to achieve his targets. Moreover, he had his own view of life. He liked freedom too much.

Question 4.
What did Einstein call his desk drawer at the patent office? Why?
Answer:
Einstein called his desk drawer at the patent office the “bureau of theoretical physics”. Einstein was actually developing his own ideas in secret and his drawer had all the evidences which could reveal the secret.

Question 5.
Why did Einstein write a letter to Franklin Roosevelt?
Answer:
With the emergence of Nazis in Germany,
Einstein emigrated to the United States. It was the fact that the Nazis had the ability to develop the atomic bomb. It could destroy the whole world. So he warned Franklin D. Roosevelt in his letter.

Dictation
(Page 53)

Question 1.
Your teacher will dictate these paragraphs to you. Write down the paragraphs with correct punctuation marks.

In 1931 Charlie Chaplin invited Albert Einstein, who was visiting Hollywood, to a private screening of his new film, City Lights. As the two men drove into town together, passersby waved and cheered. Chaplin turned to his guest and explained: “The people are applauding you because none of them understands you and applauding me because everybody understands me.”

One of Einstein’s colleagues asked him for his telephone number one day. Einstein reached for a telephone directory and looked it up. “You don’t remember your own number?” the man asked, startled. “No,” Einstein answered. “Why should I memorise something I can so easily get from a book?” (In fact, Einstein claimed never to memorise anything which could be looked up in less than two minutes.)

Long Answer Type Questions (4 marks each)
(About 80-100 words each)

Question 1:
Write down the achievements of Albert Einstein. (Board Term 1,2012, ELI-022)
Answer:
Albert Einstein was really a scientific genius. He felt at home in Mathematics but he showed keen interest in physics. After graduating from the university in Zurich he started working vigorously. With his university education he was working on relativity. After his graduation, he remained jobless. So, he gave private lessons. In 1902, he secured a job as a technical expert in the patent office in Bera. But he went on developing his own ideas. The world showered on him honors invitations. He was honored with Noble prize in 1921.

Question 2:
Einstein was an unusual child with no indication of his potential greatness. Comment.(Board Term 1,2012, ELI-039)
Answer:
Einstein’s head was larger than the usual head. He was called “Brother Boring” because he never mixed up with his classmates. He left school because he was not happy with the strict regimentation. He loved mechanical toys and thought his sister to be a toy. The head master thought him to be stupid and good for nothing and that he would never succeed in life. He also told Einstein’s father that whatever profession he chose would not matter, because “he will never make a success at anything”. This proves that Einstein was an unusual child with no indication of his potential greatness.
