Ans. Einstein loved
mechanical things from his childhood. He loved mechanical toys a lot.
After seeing his
sister, Maja, he asked about her wheels.

bad as a student. He went to high school in Munich and scored good marks in
almost every subject. But he hated the school regimentation and often clashed
with the teachers.
subjects was Einstein sharp at? Which university did he join and why?
Ans. Einstein was
sharp at subjects like mathematics and physics.
He joined the
university in Zurich because he was extra-ordinary in the field of science
specially mathematics and physics.
8. In what ways the thoughts of Einstein matched
with Mileva Maric? What was Einstein’s view about ‘Phristines’?

11. Write in your own word the special theory
of Relativity? How in a simplistic way did Einstein explain Relativity?
Ans. According to the
Special Theory of relativity, time and distance are not absolute. He provided a
formula to show the relationship between mass and energy:
Relativity in a very simplified manner. He told that, “When you sit with a nice
girl for two hours, it seems like two minutes. When you sit on a hot stove for
two minutes, it seems like two hours- That’s relativity”.
12. When did Einstein want to marry Mileva?
What did his mother think about this?
Ans. Einstein wanted to
marry Mileva after finishing his studies.
His mother was against this
marriage as she thought that Mileva being three years older than her son was
too old for him. She was also bothered about her intelligence.
13. Why did they marry and why did the couple
divorce at last?
Ans. They married in the
year of 1903 in the month of January. They got married as they loved each
other. They wrote letters mixing science with tenderness.
They got divorced at last
because Mileva thought that she was losing her intellectual ambition and was
becoming an unhappy housewife.
14. What is General Theory of Relativity? How
was it proved true? What was the effect of it?
Ans. The General Theory of Relativity
provided the new interpretation of gravity. It is the theory proposed by
Einstein that explained the extent to which the light from the stars would get
deflected due to the gravitational field of the sun.
It was proved in the year of
1919 by an eclipse of the sun which Einstein had previously calculated about
the extent to which the light from the fixed stars would be deflected through
the sun’s gravitational field.
After it was proved correct,
the newspapers proclaimed his work as “a scientific revolution”. Moreover, he
received Nobel Prize for physics.
15. Why did Einstein leave Germany? What
incident in Berlin made Einstein and other scientists in tension?
Ans. Einstein left Germany as
the Nazis came to power in Germany.
After five years the
discovery of nuclear fission in Berlin made Einstein and other scientists in

have an effect. The Americans developed the atomic bomb in a secret project of
their own and dropped it in the August 1945 on the Japanese cities of Hiroshima

born without any indication about his greatness. Albert’s mother thought him to
be freak and considered his head to be large enough. Even at the age of

headmaster of Einstein said that no matter what he would choose as his profession,
he would not be able to make success at anything.
He scored good marks
in almost every subject. Einstein was sharp at subjects like mathematics and
physics. He had continuous clashes with the teachers and as a result of which
he left the school. Then he went to
Switzerland where education was more liberal. Einstein was highly gifted in
mathematics and interested in physics. After that, he got admitted to a University in Zurich.
was the relation of Einstein, his mother and Meva Maric?
Ans. Einstein had a
great interest in subjects like mathematics and physics. Apart from these, he had
grown a special interest in a fellow student named Mileva Maric. He found her
to be a “clever creature”. She was three years older than Albert. Einstein saw an
ally against the “Philistines” with those people with whom he was constantly at
odds. They fell in love with each other. They wrote letters for each other
mixing science with tenderness. While Einstein was solving the most difficult
problems in physics, his private life was unravelling. He wanted to marry
Mileva after finishing his studies but his mother was against of hid marriage
with Mileva. She was also bothered by Mileva’s intelligence. But they finally
got married in the year of 1903 and had two sons. Later on, they got divorced
after constant fighting as Mileva thought that she was losing her intellectual
Special Theory of Relativity and General Theory of Relativity.
Ans. The Special
Theory of Relativity provided a new interpretation of gravity. It was published
in the year of 1915. According to this theory, time and distance were not
absolute. His theory was proved in the year of 1919. Einstein had properly
calculated the extent to which the light from the fixed stars would be
deflected through the gravitational field produced by the sun beforehand. The
newspapers proclaimed his work as a “scientific revolution”.
was Einstein’s take on Atom Bomb? How was it a part of his whole life?
After the Nagasaki and Hiroshima incident that occurred in August, 1945,
Einstein was deeply shaken by the extent of the destruction. He wrote a public
missive to the United Nations. In this, he proposed the formation of a world
government. But this one had no impact at all unlike the first letter to the
President Roosevelt. After that, he got involved in politics so that he could
bring an end to the arms build-up. He campaigned for peace and democracy.
died at the age of 76 and he was celebrated as a visionary and world citizen as
much as a scientific genius.
