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.

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 सिद्धांत’ पर 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 सिद्धांत’ का
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 ।

formula, ‘E’ stands for energy, ‘m’ for mass and ‘c’ for the speed of light in
a vacuum.
(d) How did this formula establish Einstein as
a scientific genius?
This
formula, having been proved to be accurate, had become the most famous formula
of the world and therefore, Einstein’s reputation as a scientific genius was

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.
Q22. How did Einstein react to the bombing of
the Japanese cities Hiroshima and Nagasaki by America?
(Textual)
Ans:
Einstein was completely shaken by the immense destruction caused due to the
bombing of the Japanese cities Hiroshima and Nagasaki by America. As a reaction
to this tragic event, he wrote a letter to the United Nations proposing the
establishment of a world government that could counter such fierce enmity among
nations.
Q23. What did Einstein campaign for after he
got involved in politics?
Ans:
After getting involved in politics, Einstein made earnest efforts for world
peace and harmony. He campaigned against the race for armaments and supported
the cause of peace and democracy.
Q24. Why does the world remember Einstein as a
“world citizen”?
Ans:
The world remembers Einstein as a world citizen because, towards the later part
of his life, he strived for the peace and well-being of the entire world and
not just his own country. He -was no longer solely a scientific genius but a
visionary as well, who felt that the solution to enmity between countries was a
world government.
