Class 9 English Chapter 4 Important Question Answers - A Truly Beautiful Mind

Short Answer Type Questions 

Q1: Why was Einstein referred to as a world citizen?
Ans: People called Einstein a world citizen because he was actively involved in campaigning for peace, democracy, and opposing war, especially after the bombing of Hiroshima and Nagasaki.

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 found it difficult to adjust, which led him to drop out.

Q3: Why did Einstein write a letter to Franklin Roosevelt?
Ans: Einstein wrote a letter to President Roosevelt because he feared that the Nazis in Germany could develop an atomic bomb after the discovery of nuclear fission. He urged Roosevelt to take action, which eventually led to the development of the atomic bomb by the U.S.

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.

Q5: Why was Einstein nicknamed "Brother Boring" by his playmates?
Ans: Einstein's peers called him "Brother Boring" because he didn’t engage in games like other children, repeated words, and had a large head, making him seem different from others.

Q6: How did Einstein’s personal life become complicated after his studies?
Ans: Einstein wanted to marry Mileva, but his mother disapproved, thinking Mileva was too old and too smart for him. This created personal tension in his life.

Q7: Why did Einstein call his desk drawer at the patent office the "bureau of theoretical physics"?
Ans: Einstein humorously referred to his desk drawer at the patent office as the "bureau of theoretical physics" because, while he was assessing inventions as part of his job, he was secretly developing his own groundbreaking ideas in physics.

Q8: How did Einstein react to the bombings of Hiroshima and Nagasaki?
Ans: Einstein was deeply shocked by the devastation caused by the bombings. He wrote to the United Nations, advocating for the establishment of a world government to prevent further destruction.

Q9: Why did Einstein show no signs of genius during his childhood?
Ans: As a child, Einstein had a large head, began speaking late, repeated his words, and didn’t interact much with others, which did not indicate his future genius.

Q10: What kind of toys fascinated Einstein as a child?
Ans: Einstein was fascinated by mechanical toys because they reflected his interest in scientific principles. He preferred them over playing with other children.

Q11: Why did Einstein look for wheels on his newborn sister's body?
Ans: Einstein, intrigued by mechanical toys, humorously expected his sister to have wheels like a toy when she was born, reflecting his 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 wanted him to. He became quite skilled and continued playing it throughout his life.

Long Answer Type Questions 

Q1: Write about the achievements of Albert Einstein.
Ans: Albert Einstein was a scientific genius with a deep interest in mathematics and physics. After graduating from Zurich University, he worked on the theory of relativity, but faced initial unemployment and gave private lessons. He later secured a job at the patent office in Bern, which allowed him to develop his own ideas. In 1905, he published groundbreaking papers, including his famous formula E = mc². Einstein gained worldwide recognition and was awarded the Nobel Prize in Physics in 1921 for his work on the photoelectric effect. His achievements revolutionized physics, and he became a global figure, honored with numerous accolades.

Q2: How was Einstein an unusual child, with no signs of future greatness?
Ans: As a child, Einstein was quiet, had an abnormally large head, and didn't engage much with other children, leading to his nickname "Brother Boring." His headmaster believed he would never succeed in life. He left school because he disliked its strict rules and regimentation. His peculiar childhood behavior and lack of academic success early on did not indicate the greatness he would later achieve as a physicist.

Q3: What impact did Einstein’s letter to President Roosevelt have on the world?
Ans: On the advice of colleagues, Einstein wrote a letter to President Roosevelt, warning him about the possibility of Nazi Germany developing an atomic bomb. This letter led to the secret development of the atomic bomb by the U.S. The bomb was eventually dropped on Hiroshima and Nagasaki in August 1945, ending World War II. Einstein was deeply saddened by the destruction and later advocated for a world government to prevent such devastation in the future.

Q4: Describe Einstein’s education journey from school to university.
Ans: Einstein’s early education was unremarkable. His headmaster had a low opinion of him, and though he did well in subjects, the strict discipline of his Munich school clashed with his independent spirit, leading him to leave. He found a more liberal environment in Switzerland, where he finished school and honed his talents in mathematics and physics. In 1900, he graduated from the University of Zurich, which laid the foundation for his future scientific discoveries.

Q5: What research and theories proved Einstein’s genius, and how was he rewarded?
Ans: Einstein's research in the early 20th century cemented his reputation as a scientific genius. In 1905, while working at the patent office, he published his Special Theory of Relativity, challenging the traditional understanding of time and space. His equation, E = mc², was revolutionary. Later, in 1915, his General Theory of Relativity further demonstrated his brilliance by predicting phenomena like light bending under gravity. He was awarded the Nobel Prize in 1921 for his work on the photoelectric effect and continued to receive numerous accolades throughout his life for his groundbreaking contributions to science.
