Summary in English (Part 1):

The story begins with Albert Einstein’s early life. Born in Germany, he was slow in speaking and disliked the regimentation of school life. Despite this, he excelled in mathematics and had a passion for science. After graduating, he worked in a patent office and began developing his scientific ideas, including the famous equation E = mc².

Summary in English (Part 2):

Einstein’s personal life was marked by challenges, including his troubled marriage with Mileva Maric. However, his scientific contributions continued, and he gained international recognition. He later advocated for peace and democracy, especially after the horrors of World War II and the atomic bombings.

   • Mileva and Einstein’s mother (10)
   • A letter that launched the arms race (15)
   • A desk drawer full of ideas (8)
   • Marriage and divorce (11)
2. 2. Who had these opinions about Einstein?
   • (i) He was boring. — Einstein’s playmates in his childhood.
   • (ii) He was stupid and would never succeed in life. — A headmaster at Einstein’s school.
   • (iii) He was a freak. — Einstein’s mother.
3. 3. Explain what the reasons for the following are.
   • (i) Einstein leaving the school in Munich for good. — He left the school because of the strict regimentation that conflicted with his liberal and questioning mind.
   • (ii) Einstein wanting to study in Switzerland rather than in Munich. — He preferred Switzerland because it was more liberal, and the educational system encouraged independent thinking.
   • (iii) Einstein seeing in Mileva an ally. — Einstein saw in Mileva an ally because she shared his intellectual interests and opposed the traditional role expected of women.
4. 4. What did Einstein call his desk drawer at the patent office? Why?

   Einstein called his desk drawer at the patent office "the bureau of theoretical physics" because he worked on his scientific papers secretly while doing his official work.

5. 5. Why did Einstein write a letter to Franklin Roosevelt?

   Einstein wrote a letter to Franklin Roosevelt to warn him that Germany might be developing an atomic bomb, urging the U.S. to accelerate its own nuclear research.

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

   Einstein was deeply shaken by the bombing of Hiroshima and Nagasaki. Although he had encouraged the development of atomic energy, he was horrified by its destructive use and worked for world peace thereafter.

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

   The world remembers Einstein as a “world citizen” because of his commitment to global peace and democracy. He advocated for disarmament and international cooperation, especially after witnessing the horrors of atomic warfare.

8. 8. Here are some facts from Einstein’s life. Arrange them in chronological order.
   • [ ] Einstein publishes his special theory of relativity.
   • [ ] He is awarded the Nobel Prize in Physics.
   • [ ] Einstein writes a letter to U.S. President, Franklin D. Roosevelt, and warns against Germany’s building of an atomic bomb.
   • [ ] Einstein attends a high school in Munich.
   • [ ] Einstein’s family moves to Milan.
   • [ ] Einstein is born in the German city of Ulm.
   • [ ] Einstein joins a university in Zurich, where he meets Mileva.

Writing Newspaper Reports : Einstein’s Manuscript Unearthed

21 August 2005: An original handwritten manuscript of the renowned physicist Albert Einstein has been unearthed, creating excitement among the scientific community. The document, believed to contain groundbreaking insights, has been hidden from public view for decades.

The discovery was made by Rowdy Boeynik, a student at the University of the Netherlands. Boeynik was researching old papers belonging to an old friend of Einstein when he stumbled upon this precious manuscript. The finding was made on 21 August 2005, and it has since sparked interest in the world of physics.

The 16-page document is dated 1924 and contains Einstein’s last known theory regarding the behaviour of atoms at low temperatures. This theory is now famously referred to as the Bose-Einstein condensation. Fingerprints of Albert Einstein were found on the document, further authenticating its importance.

The manuscript will be preserved at Leyden University, the same institution where Einstein was awarded the Nobel Prize. This discovery is expected to contribute significantly to the ongoing study of Einstein’s works and the history of quantum physics.
