THEME

This brief sketch of the life and achievements of the great genius Albert Einstein, reveals that extraordinary personalities with exceptional intellectual capabilities are not necessarily noticed during the early years. The author focuses on two aspects of Einstein’s personality – as a scientist and as a human being. As a scientist, his marvellous discoveries created a revolution and as a human being, he worked towards peace and democracy in the world.





TITLE

 The title of this biographical feature “A Truly Beautiful Mind” is very appropriate as it encompasses both the intelligence of Einstein and his humanistic tendencies. As a genius, he made an immense contribution to the world of science by presenting startling theories and as a human being, he preached for peace and democracy. Thus, his mind was really beautiful and teeming with new ideas and human concerns.

MESSAGE





This account of the life and personality of the famous scientist Einstein gives us the message that a beautiful mind possesses not only innovative ideas but also makes sincere efforts to use these ideas for the well being of mankind. Science should be solely devoted to the promotion of worldwide peace and prosperity. If used for destructive purposes, the scientific inventions and discoveries can wreak havoc on the earth.



CHARACTER





Albert Einstein

 Albert Einstein has been portrayed as a great intellectual genius and a peace-loving human being with liberal ideas. As an intellectual, he created a revolution in the field of science, particularly physics. Ma human being, he spread the message of love, liberty and peace.

During his childhood, Einstein did not show any traces of intelligence. He was a slow child who started speaking very late. Even his mother considered him to be a freak and the headmaster of his school had such a negative opinion about him that he stated that Einstein would never achieve success in any career that he chi” However, Einstein proved to be a good student as he had s13’en interest and skills in mathematics and physics and he also scored in all other subjects.

Einstein’s love for freedom dated back to his school days. He felt suffocated in his school in Munich because of excessive discipline. He opted to study in Switzerland in a school with a liberal environment. He left Germany for America when the dictatorial Nazis took over because he was averse to every type of authority.



Though a great scientist, Einstein was a lover of arts and literature. He was against philistinism (ignorance of or hostility towards art and culture). He fell in love with a Serbian girl Mileva Maric because she held similar ideas about art. As a scientist, his theories of relativity and gravity created a stir in the world of science. He was awarded the Nobel Prize and got numerous other honours.



Einstein was a great lover of mankind. He wanted a world government. He was perturbed by the destructive use of science when the atom bomb was dropped over Hiroshima and Nagasaki. He spent the rest of his life spreading the message of peace and democracy. Thus, Einstein’s traits as a scientific genius and a peace-loving human being with a deep love for freedom are amply highlighted in this biographical account.

Short and Simple Summary of the lesson in English– (Lesson Name)/ Summary in simple Words/ Critical appreciation of the lesson – (Lesson Name)

Summary in ENGLISH
Albert Einstein was born on March 14, 1879, in the German city of Ulm. He was a normal looking child. His mother thought him an abnormal child. He began to speak very late. And when he spoke he repeated each word twice. The other children made fun of him. So he used to play all alone. lie loved to play with mechanical toys. When he was six years old, he learnt to play the violin.



            Albert Einstein went to high school in Munich. He was a good student. Ile scored good marks in all subjects. But he did not like the strict discipline of the school. He often got clashed with his teachers. So he left the school for good.

After long discussions, he agreed to continue his study in Switzerland. He was highly gifted in mathematics and interested in physics. After passing high school, he joined Zurich University. There he got interested in a fellow student Mileva Marie. He found an ally in her. She was a young Serb. She was very intelligent. They fell in love and later they got married in 1903.



Albert graduated in 1900, at the age of 21. He was unemployed. the lie worked as a teaching assistant. In 1902, he got the job of a technical expert in a patent office in Bern. His job was to assess other people’s discoveries. He was secretly developing his own ideas. He published his famous paper in 1905 on ‘Special Theory of Relativity’, according to which time and distance are not absolute.

Einstein’s new personal chapter coincided with his rise to world fame. In 1915, he had published his ‘General Theory of Relativity’, which provided a new interpretation of gravity. Einstein has correctly calculated in advance the extent to which the light from fixed stars would be deflected through the sun’s gravitational field. Einstein received the Nobel Prize for Physics in 1921. He was showered with honours and invitations from all over the world and lauded by the press.



 When the Nazis came to power in Germany in 1933, Einstein emigrated to the United States. Five years later, the discovery of nuclear fission in Berlin had American physicists in an uproar.

 At the urging of a colleague, Einstein wrote a letter to the American president Franklin D. Roosevelt, on August 2, 1939, in which he warned against the danger of atom bombs. His words influenced Roosevelt. The Americans developed the atomic bomb in a secret project of their own and dropped it on the Japanese cities of Hiroshima and Nagasaki in August 1945.



 Einstein was deeply shaken by the extent of the destruction. This time he wrote a long letter to the United Nations. In it, he proposed the formation of a world government. Einstein got ever more involved in politics using his popularity to campaign for peace and democracy. When Einstein died in 1955 at the age of 76. he was celebrated as a visionary and world citizen as much as a scientific genius.

LONG ANSWER QUESTIONS
                                

Q1.Write a short note on Einstein’s education from school to university.

Ans: As a young boy, Einstein did not show any symptoms of an intellectual genius. His headmaster had a very poor opinion about him and he even declared that Einstein would fail in any career that he chose. However, as he grew up and joined a school in Munich, he showed appreciable progress in studies scoring good marks in almost all the subjects. But the strict discipline of the school was not in accordance with the free spirit of Einstein. As a result, he frequently had scuffles with his teachers. Being a person of liberal ideas, he felt so suffocated that he ultimately left that school for good. He chose to complete his studies in a school in Switzerland where the environment was more liberal as compared to Munich. Highly gifted in mathematics and having a great interest in Physics, Einstein joined the university in Zurich after completing school and from where he graduated in 1900.

Q2. What researches and theories proved that Einstein was a true genius? How was he rewarded for his scientific achievements?

Ans: Einstein proved to be an intellectual and scientific genius after the completion of his university education. Although he was jobless for some time and gave private tuitions, he finally got a job of a technical expert in a patent office in Bern. Here, along with the job, he kept developing secretly his own ideas and came out with the publication of his famous research paper on ‘Special Theory of Relativity’, according to which time and distance are not absolute. His theory about the relationship between mass and energy was developed into the world famous formula E = mc2, and this equation made him a renowned scientist. Einstein earned international acclaim with the publication of his General Theory of Relativity which enabled him to calculate in advance the extent of the deflection of light from fixed stars as it passed through the gravitational field of the sun. The theory was declared as “a scientific revolution” by the newspapers. For his contribution to the development of science, Einstein was awarded the Nobel Prize for Physics in 1921. After this, a number of honours were bestowed upon him and he was invited by different countries in the world. Newspapers too hailed his scientific genius.



Q3. The author talks about two important letters that Einstein wrote -one to President Franklin D. Roosevelt and the other to the United Nations. What prompted Einstein to write these letters? What impact did they make?

Ans: At the insistence of a colleague, Einstein wrote a letter to the American President, Franklin D. Roosevelt in 1939 warning him that the atomic bomb, if made and used by Germany, could not only destroy the whole port on which it could be dropped but also the territory surrounding it. The impact of the letter was both deep and rapid as the Americans secretly developed their own atomic bombs which were dropped on Hiroshima and Nagasaki in Japan in 1945. As expected, these bombs caused terrible destruction. The large-scale damage caused by these bombings on Japan perturbed Einstein so much that this time he wrote a letter to the United Nations. In this letter, he proposed that there should be only one government in the world. This would put an end to the enmity between nations and hence stop the massacres caused in the name of wars. But this letter did not have any impact. Thus, unlike the letter to Roosevelt, Einstein’s letter to the United Nations failed to evoke any response.

Q4.Which values does the life of Einstein teach you?

Ans: Einstein was not only a great scientist but a man with love for peace. His life history contains in itself the moral lesson that one must love one’s fellow beings and all the discoveries of science should be oriented towards the aim of establishing peace. Einstein had written a letter to the American President Roosevelt to warn him against the destructive atom bomb that Germany would build on the principle of nuclear fission. But Einstein was terribly shocked when America caused a large scale destruction in Japan by dropping an atom bomb on Hiroshima and Nagasaki. Einstein made sincere efforts to spread the message of peace. He even wrote a letter to the United Nations proposing that a world government should be established. He did not use his popularity for selfish or personal gains. Instead, he worked for furthering the cause of democracy and peace. He was never carried away by his achievements; on the contrary, the honours bestowed on him encouraged him to work more for the welfare of humanity. The life of Einstein thus inspires in us the values of sincere work, devotion to humanity, selfless service of mankind, and love of peace.

Q5.What important lessons can Educationists today learn from the biographical sketch of the great scientist, Einstein?



Ans: “A Truly Beautiful Mind” forms a powerful comment on the education system in many institutions. A brief life sketch of the great scientist reveals that Einstein was not a fast learner at the early stage of schooling. One of his teachers had remarked that he would not succeed in any course he took. But the reality proved to be otherwise. Einstein turned out to be an intellectual genius. Educationists today can learn several important lessons from his education career. First, teachers must encourage all the students all the times. Instead of making negative remarks, they should discover the individual potential of students and try to develop it to the maximum. Second, students should be provided with a liberal and conducive environment, so that they feel encouraged to think originally and their ideas may find nourishment instead of being smothered. Einstein felt much suppressed in his school in Munich because of the stifling regimentation over there. Such strictness made him leave the school for good and move to Switzerland. His talent bloomed in the liberal environment of the university in Zurich. Third, all stakeholders of the education system today should be free from all kinds of biases and prejudices.

SUMMARY IN HINDI
एल्बर्ट आइंसटाईन का जन्म 14 मार्च , 1879 को जर्मनी के उल्म नामक शहर में हुआ था । वह एक सामान्य-सा दिखाई पड़ने वाला बालक था । उसकी माता तो उसे एक विचित्र बालक मानती थी । उसने बहुत देरी से बोलना शुरू किया । ओर जब वह बोलता था तो प्रत्येक शब्द को दो बार बोलता था । दुसरे बच्चे उसका मजाक उड़ाते थे । इसलिए वह अकेला ही खेलता रहता था । वह मैकेनिकल (यांत्रिक) खिलौनों के साथ  खेलना पसंद करता था । जब वह मात्र 15 बर्ष का था तो उसने वायलिन बजाना सीख था ।

एलबर्ट आइंसटाईन को म्यूनिख में उच्च-विद्यालय में भेजा गया । वह एक अच्छा विद्यार्थी था । वह सभी विषयों में अच्छे अंक प्राप्त करता था । लेकिन उसे स्कूल का कठोर अनुशासन पसंद नहीं था । वह प्राय: अपने  अध्यापकों के साथ झगड़ पड़ता था । इसलिए  उसने हमेशा के लिए ही स्कूल को छोड़ दिया ।



लंबे वार्तालाप के पश्चात वह स्विटूजरलैंड में अपनी पढाई को जारी रखने के लिए सहमत हो गया । गणित में तो वह बहुत विशिष्टता प्राप्त था तथा भौतिकी में भी उसकी बहुत रुचि थी । हाई स्कूल की परीक्षा पास करने के पश्चात उसने ज्यूरिक विश्वविद्यालय में प्रवेश ले लिया । यहाँ उसकी अपनी एक सहपाठी मिलेवा मैरिक से लगाव हो गया । उसने उसमें एक साथी ढूंढ लिया । वह एक  युवा सर्वियाई युवती थी । वह वहुत ही बुद्धिमान थी । उन दोनों में प्यार हो गया और बाद में दोनों ने 1903 में शादी कर ली ।



एल्बर्ट ने सन 1900 में 21 वर्ष की आयु में स्नातक की उपाधि प्राप्त की । वह बेरोजगार था । उसने एक सहायक शिक्षक की नौकरी कर ली । 1902 में,  उसे बर्न में एक पेटेंट कार्यालय में नौकरी मिल गई । उसका कार्य दूसरे लोगों के अविष्कारों का मूल्यांकन  करने का था । वह गुप्त रुप से अपने सिद्धांतों को भी विकसित कर रहा था । उसने सापेक्षता के विशेष सिद्धांतपर  1905 में अपना विख्यात पत्र प्रकाशित किया, जिसके अनुसार समय और दूरी अपने आप में स्वतंत्र नहीं हैं ।

आइंसटाईन के जीवन का नया अध्याय विश्व में उसके उदय से प्राप्त प्रसिद्धि से मेल खाता है । 1915 में उसने सापेक्षता के सामान्य सिद्धांतका  प्रकाशन किया , जिसने गुरुत्व-बल की एक नई व्याख्या की । आइंसटाईन ने सही सही गणना कर ली थी कि स्थिर सितारों से कितने समय में सूर्य गुरुत्व बल के कारण प्रकाश का अपवर्तन हो जाता है । 1921 में आइंसटाईन को

भौतकी के क्षेत्र में नोबल पुरुस्कार प्राप्त हुआ । उसे सारे विश्व में सम्मान और निमंत्रण पत्र प्राप्त हुए और मीडिया के माध्यम से प्रसिद्ध हुआ ।
जब 1933 ई. में जर्मनी में नाजीवादी पार्टी सत्ता में आई तो  आइंसटाईन जर्मनी छोड़कर अमेरिका चला गया । पांच वर्ष बाद जब जर्मनी ने नाभिकीय विखंडन किया तो अमेरिका के भौतिकीशास्त्री  परेशानी में आ गए । अपने एक सहकर्मी की सलाह पर आइंसटाईन ने अमेरिका के राष्ट्रपति फ्रिंकालिन डी. रुजवेल्ट को परमाणु बम के भारी खतरे के बारे में चेतावनी दे डाली । उसके शब्दों ने रूजवेल्ट को प्रभावित किया । अमेरिका वालों ने एक गुप्त योजना के अंतर्गत परमाणु बमों का विकास किया और अगस्त,1945 में उन्हें जापान  के हिरोशिमा और नागासाकी शहरों के ऊपर गिराया ।

आइंसटाईन  युद्ध को तबाही से बहुत अधिक विचलित हो उठा । इस बार उसने संयुक्त राष्ट्र के नाम एक लम्बा पत्र लिखा जिसमें उसने  विश्व सरकार बनाने का प्रस्ताव रखा। आइंसटाईन राजनीति में और अधिक   लेने लग गया और उसने ख्याति को शांति और लोकतंत्र की स्थापना में प्रयोग क्रिया । जव 1955 में 76 वर्ष की आयु में आइंसटाईन की मृत्यु हुई तो लोगों  ने उसे एक  महान वैज्ञानिक के साथ-साथ एक भविष्य-द्रष्टा तथा विश्व नागरिक के रूप में भी याद किया ।

SHORT ANSWER QUESTIONS


Q1. Who is a ‘freak’? Why did Einstein’s mother think him to be a ‘freak’?

Ans: A ‘freak’ is a word used disapprovingly for a person who is unusual in looks and behaviour. Einstein’s mother thought him to be a ‘freak’ because his head seemed too large to her. This made him look different from the other children of his age.

Q2. During his childhood, Einstein did not show any traces of becoming a genius one day. How?

Ans: As a child, Einstein had a large head and did not start to speak till he was two-and-a-half years old. Finally, when he did speak, he used to utter everything twice. He could not interact freely with his playmates either. All this showed the absence of any traces in him of becoming a genius one day.

Q3. Why did Einstein’s playmates call him “Brother Boring”?

Or



 Why did Einstein play all alone when he was a child?

Ans: Einstein did not know what to do with other children. His shy and introvert nature made his company boring to his playmates. So, they teased him as “Brother Boring” and did not include him in their games. Therefore, he played all alone when he was a child.

Q4. What kind of toys attracted the attention of Einstein when he was a child? Why?

Ans: Einstein could not enjoy the company of playmates because of his introvert nature. Instead as a child, he was attracted only by mechanical toys. It showed his scientific temperament since mechanical toys work on some kind of scientific principles.

 Q5. Why did Einstein try to look for wheels on the body of his newly born sister?



Ans: Einstein was much too interested in mechanical toys and had scientific inclinations. When his sister was born, he thought her to be a new toy; that is why he tried to search for wheels on her body.

Q6. What was the opinion of the school headmaster about Einstein?

Ans: The school headmaster considered Einstein to be a good-for-nothing boy. He was of the opinion that Einstein would never succeed in any profession. Therefore, choice of profession would not make any difference in the results of his efforts.

Q7. Which musical instrument did Einstein begin to learn? Why?

Ans: Einstein began to learn to play upon the violin at the young age of six. He kept this interest alive throughout his life and became a gifted amateur violinist. He began learning the violin because his mother wanted him to.

 Q8. How did Einstein perform in various subjects while studying in Munich?

Ans: Although as a young child Einstein was very slow, still while studying in Munich, he showed great progress in almost all the subjects and scored very good marks. He showed a special interest in Physics and Mathematics.

Q9. Why did Einstein leave the school in Munich?                                                                          (Textual)

 Ans: Einstein left the school in Munich because of the stifling environment that suppressed his scientifically curious mind. The excessively stern discipline and rigid rules in that school led to frequent clashes with his teachers. He thus began to feel that such a place was inappropriate for a liberal person like him.

Q 10. Why did Einstein shift to Switzerland to continue his education?                                (Textual)



Ans: Einstein shifted to the German-speaking part of Switzerland to continue his education because he had left his school in Munich midway. This new place was more liberal than Munich and Einstein’s curious and free temperament got a favourable environment over here.

 Q11. Why did Einstein see an ally in Mileva Maric?                                                                        (Textual)

Ans: Einstein saw an ally in his Serbian fellow student Mileva Maric because, like him, she too was against philistines – the people who have disregard for art and culture. As both shared similar tastes, Einstein developed a liking for her and they both fell in love.

Q12. What did Einstein call his desk drawer at the patent office? Why?                                (Textual)



Ans: Einstein jokingly called his desk drawer at the patent office as “Bureau of theoretical physics”. He did so because his office job required him to assess the inventions of other people while he secretly developed his own ideas regarding his keen interest in Physics.

 Q13. Why did Einstein’s mother not want him to marry Mileva?

Ans: There were two reasons for Einstein’s mother not wanting him to marry Mileva. Firstly, the girl was three years older than Einstein and secondly, she was much too intelligent – ‘a book’ just like him, in his mother’s opinion.

Q14. Why did Einstein’s marriage with Mileva not survive long?



Ans: Although Einstein and Mileva had been in love, still their marriage did not survive long because Mileva gradually lost her intellectual vigour and aspirations. She became a frustrated housewife. There were frequent scuffles between the couple which resulted in their ultimate divorce in 1919.

Q15. What was the new personal chapter in Einstein’s life? How did it coincide with his fame?



Or

“Einstein’s new personal chapter coincided with his rise to world fame”. What new personal chapter in Einstein’s life is the author talking about here?

Ans: The new personal chapter in Einstein’s life was his marriage to his cousin Elsa in the year 1919 immediately after his divorce from Mileva. This chapter coincided with his rise to world fame when his paper on General Theory of Relativity, published in 1915, was found to be accurate due to the proof that came through the eclipse of the sun in 1919.

Q16. When and for what did Einstein gain international fame?

Ans: Einstein gained international fame when his paper on General Theory of Relativity was found to be accurate in 1919. As per this theory, the calculations made by Einstein in advance about the deflection of light in the solar gravitational field during the eclipse were proven true. This theory was treated as “a scientific revolution.”

Q17. How was Einstein honoured for his achievements?

Ans: Honours came pouring in for Einstein after his theories proved him to be a scientist with exceptional abilities. He was awarded the prestigious Nobel Prize for Physics in 1921. Honours and invitations were conferred on him from all over the world. The newspapers too applauded his genius.



Q18. Why did Einstein leave Germany and emigrate to America?

 Ans: Einstein had always been a lover of freedom and liberal ideas. The Nazi government, which came to power in 1933, was very suppressive and autocratic. Therefore, Einstein left Germany and emigrated to America.

Q19. Why did the discovery of nuclear fission in Berlin disturb the American physicists?

                                                                                                Or

 ‘The discovery of nuclear fission in Berlin had American physicists in an uproar”. Why?

Ans: The American physicists were disturbed by the discovery of nuclear fission in Berlin because they were afraid that Germany would make an atom bomb and use it for destructive purposes.

 Q20. Why did Einstein write a letter to Franklin Roosevelt?                                                       (Textual)



 Ans: Einstein wrote to the American president, Roosevelt, because he wanted to forewarn him regarding the massive destructive power of the atom bomb which the Germans were expected to build after the discovery of nuclear fission. If dropped on a port, the bomb could destroy the whole port as well as the area around it.

Q21. What was the effect of Einstein’s letter on Roosevelt?

Ans: The warning sounded by Einstein in his letter to Franklin D. Roosevelt about how dangerous an atom bomb made by German)’ could be, had a lightening effect on the Americans. They at once rose to action and secretly developed an atom bomb of their own.
