Q2. Why did Albert Einstein leave his school? 

Ans: Einstein left school because he was unhappy with its rigid and strict system. He felt suffocated by its regimentation and struggled to adjust, which ultimately led him to drop out.

Q3. Why did Einstein write a letter to Franklin Roosevelt? 

Ans: Einstein wrote a letter to President Roosevelt due to his concerns that the Nazis in Germany might create an atomic bomb after the discovery of nuclear fission. He urged Roosevelt to take action, which ultimately contributed to the U.S. development of the atomic bomb.

Q4. What is Einstein’s Special Theory of Relativity? 

Ans: Einstein’s Special Theory of Relativity states that time and distance are relative and not absolute. This theory led to the famous equation E = mc², which describes the relationship between mass and energy.Einstein Q5. Why was Einstein nicknamed "Brother Boring" by his playmates? 

Ans: Einstein was nicknamed “Brother Boring” by his playmates for several reasons:

• He often did not participate in games like the other children.
• He had a tendency to repeat words, which made him stand out.
• His large head contributed to a perception of him being different.

Q6. How did Einstein’s personal life become complicated after his studies? 

Ans: Einstein's personal life became complicated due to several factors:

• He wished to marry Mileva, but his mother disapproved.
• His mother believed Mileva was too old and too intelligent for him.

This disapproval caused significant tension in his life.

Q7. Why did Einstein call his desk drawer at the patent office the "bureau of theoretical physics"? 

Ans: Einstein jokingly called his desk drawer at the patent office the "bureau of theoretical physics" because:

• While evaluating inventions for his job, he was also working on his own important ideas in physics.
• It reflected his dual role as a patent clerk and a pioneering scientist.

Q8. How did Einstein react to the bombings of Hiroshima and Nagasaki? 

Ans: Einstein was profoundly shocked by the devastation caused by the bombings of Hiroshima and Nagasaki. He expressed his feelings through a letter to the United Nations, urging the need for:

• The establishment of a world government
• Measures to prevent future destruction

Q9. Why did Einstein show no signs of genius during his childhood? 

Ans: As a child, Einstein exhibited several traits that did not suggest his future genius:

• He had a large head, which some might have viewed as unusual.
• He began speaking late compared to his peers.
• He often repeated his words.
• He was not very social and rarely interacted with others.

These characteristics led many to underestimate his potential.

Q10. What kind of toys fascinated Einstein as a child? 

Ans: Einstein was particularly fascinated by mechanical toys as a child. These toys captured his interest in scientific principles and concepts. He often preferred playing with them rather than engaging in activities with other children.

Q11. Why did Einstein look for wheels on his newborn sister's body? 

Ans: Einstein, fascinated by mechanical toys, humorously expected his sister to have wheels like those toys upon her birth. This reflects his innate scientific curiosity.

Q12. Which musical instrument did Einstein learn to play and why? 

Ans: Einstein began learning the violin at the age of six because his mother encouraged him to do so. He became quite skilled and continued to play throughout his life.

Einstein learnt Violin

Q13. Why did Einstein move to Switzerland for his education?

Ans: Einstein moved to Switzerland for several reasons:

• The educational system was more open-minded compared to Munich.
• He found the rigid structure of the Munich system stifling.
• Switzerland offered a more flexible approach to learning.

Q14. Why did Einstein see Mileva Maric as an ally? 

Ans: Einstein viewed Mileva Maric as an ally due to their shared interests:

• Both were passionate about science and art.
• They expressed a mutual disdain for philistines, those who overlooked culture.

Long Answer Type Questions 

Q1. Write about the achievements of Albert Einstein. 

Ans: Albert Einstein was a scientific genius known for his remarkable contributions to mathematics and physics.

Key achievements include:

• After graduating from Zurich University, he initially struggled to find employment and gave private lessons.
• Secured a position at the patent office in Bern, where he could explore his ideas.
• In 1905, published groundbreaking papers, including the famous formula E = mc².
• Awarded the Nobel Prize in Physics in 1921 for his work on the photoelectric effect.

Einstein's achievements transformed the field of physics and established him as a global icon, earning him numerous accolades.

Q2. How was Einstein an unusual child, with no signs of future greatness? 

Ans: As a child, Einstein was quiet and had an unusually large head. He often avoided interactions with other children, earning him the nickname "Brother Boring." His headmaster even predicted that he would never succeed in life.

Einstein struggled with the strict rules and regimentation of school, which led him to leave. His early behaviour and lack of academic success did not hint at the remarkable achievements he would later attain as a physicist.

Q3. What impact did Einstein’s letter to President Roosevelt have on the world? 

Ans: Einstein's letter to President Roosevelt had significant global consequences:

• Einstein warned Roosevelt about the potential of Nazi Germany developing an atomic bomb.
• This prompted the United States to start the secret Manhattan Project to develop its own atomic bomb.
• The bomb was ultimately used in August 1945 on Hiroshima and Nagasaki, leading to the end of World War II.
• Einstein later expressed deep sadness over the destruction and advocated for a world government to prevent future atrocities.

Q4. Describe Einstein’s education journey from school to university. 

Ans: Einstein’s early education was quite unremarkable:

• His headmaster held a low opinion of him.
• Despite performing well academically, he struggled with the strict discipline of his Munich school.
• This clash with authority led him to leave the school.

In Switzerland, he discovered a more liberal educational environment:

• He completed his schooling there.
• He particularly excelled in mathematics and physics.

In 1900, he graduated from the University of Zurich, which was crucial for his future scientific achievements.

Q5. What research and theories proved Einstein’s genius, and how was he rewarded?

Ans: Einstein's research in the early 20th century established him as a scientific genius. Key achievements include:

• In 1905, while at the patent office, he published the Special Theory of Relativity, which transformed the understanding of time and space.
• The famous equation E = mc² emerged, marking a revolutionary idea.
• In 1915, he introduced the General Theory of Relativity, predicting phenomena such as the bending of light due to gravity.

In recognition of his work, he was awarded the Nobel Prize in 1921 for his research on the photoelectric effect. Throughout his life, he received numerous accolades for his groundbreaking contributions to science.
