Question 1:

Who do you think of, when you hear the word ‘genius’? Who is a genius- what qualities do you think a genius has?

Answer:

I think of Albert Einstein when I hear the word ‘genius’.

A genius is a person with exceptional intellectual or creative abilities. I think a genius has a strong drive, devotion and curiosity to gain knowledge. He works patiently and with great concentration. He is imaginative and solves problems with an open mind.  He is a versatile person who is not only perfect in his field of work but also devotes energy towards bettering the society.

(iv) What do these tell you about Einstein?

Answer:

(i) Albert Einstein left the school in Munich because he hated the school’s strict and controlled environment, and often had disagreements with his teachers.

(ii) According to Einstein, Switzerland was more liberal than Munich. Hence, he wanted to study in Switzerland.

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”. This was because the drawer was where he used to store his secretly developed ideas.

Question 5:

Why did Einstein write a letter to Franklin Roosevelt?

Answer:

Einstein wrote a letter to Franklin Roosevelt to warn him of the fatal consequences of an atomic explosion.

Question 6:

How did Einstein react to the bombing of Hiroshima and Nagasaki?

Einstein was profoundly disturbed by the magnitude of the destruction caused by the bombing of Hiroshima and Nagasaki. He even wrote a public letter to the United Nations proposing the formation of a world government. Gradually he became more and more involved in politics, attempting to bring about world peace.

Question 7:

Why does the world remember Einstein as a “world citizen”?

Answer:

Einstein is remembered as a “world citizen” as much as a genius scientist because of his efforts towards world peace and democracy, and for his crusade against the use of arms.

Your report could begin like this:

Student Unearths Einstein Manuscript

21 AUGUST 2005. An original handwritten Albert Einstein manuscript has been unearthed at a university in the Netherlands …

Answer:

Student Unearths Einstein Manuscript

By a Staff Reporter

Netherlands, 21 AUGUST 2005. An original handwritten Albert Einstein manuscript has been unearthed at a university in the Netherlands. The yellowed 16-page German manuscript was dated December 1924.

Rowdy Boeynik, a student in the University of the Netherlands, was researching papers belonging to an old friend of Einstein when he stumbled upon the manuscript. The fingerprints of Einstein have been traced on these research papers.

The document, titled ‘Quantum theory of the monatomic ideal gas’, contains Einstein’s work on what is now known as the Bose-Einstein condensation. It concerns the behavior of atoms at a low temperature, the last major work of the scientific genius.

The manuscript will be kept at Leyden University where Einstein got the Nobel Prize for Physics in 1921.
