2 Answer the questions briefly
a) What did Bhabha actually want to pursue, when he was sent to Cambridge to study Mechanical Engineering?
He wanted to pursue Physics. He was very much interested in the subject. But due to the force of his family member and because of the attachment with his family members towards Tata Steels, He had to pursue Mechanical engineering. But his actual interest was that of Physics.
b) During his educational travel, who were the eminent scientists Bhabha met in Europe?
Enrico Fermi, Wolfgang Pauli, Neils Bohr were the scientists whom Bhabha met during his educatonal travel. Enrico Fermi form Rome, Italy who credited with the creation of the world’s first nuclear reactor. Wolfgang Pauli from Zurich, Bohr from Denmark.
c) What were the most important traits of Bhabha, which were clearly displayed in his inititative to form Tata Institute of Fundamental Research.
A) Bhaba was very eager to promote his research in Fundamental Physics.He had a clear view of his plan to implement some progress. He knew very well that there was lack of institutions in India. Bhaba was desirous about the developmnt of atomic energy for the collaboration internationally.Bhaba has the capabilities. He has future vision.
D) Expalain in brief Bhabha’s theoryon the hitting of cosmic rays on earth’s atmoshphere
A) Cosmic rays are highly charged, high energy particles that come from outer space and travel almost at the speed of light and bombard the earth’s atmosphere in all directions from outer space. When they do so they are slowed down and broken up by the earth’s atmosphere. These showers mainly consist of electrons and protons.
E) Which institute did Bhabha help found in Bombay Whose help did he seek in doing so?
A) Tata Institute of Fundamental Research (TIFR). He sought the help of Tata TRUST and corresponded with JRD Tatat and Sir Sorab Saklarvala and sent a formal proposal.
F) What capabilities did Bhabha develop for the Apsara reactor?
A) Sourching of Uranium, purification of fissile materials to designing, fabrication and installing nuclear reactors and their various components.
G) What is Meson theory? Explain in brief.
A) Meson theory, according to Bhabha, was that the positive or negative mesons should spontaneously decay into a positron or electron. He duduced that the time of disintegration of the mesons in longer when the particle is in motion. Bhabha had proposed vector nature of the meson fields as aginst the original Yukawa’s theory of mesons being scalar particles.
H) Why did Bhaba send scientists abroad for training?
A) The idea was taht they would get to know more about the advancements going on and would also serve as trainers for the new crop of scietists.
I) What were the objectives Bhabha wanted to fulfil with the nuclear programme?
A) To build up resources towards the INDIAN NUCLEAR PROGRAMME.
j) What was the most devastating event during the World War 11 ?
A) Japan had to face the ultimate brunt of the atom bomb. The U.S. army dropped atom bombs on Japanese towns of Hiroshima and Nagasakin on 6 and 9 August 1945 respectively.
K) Which form of art did Bhabha pursue? Also name the forms of this art he worked on
A) Bhabha was the lover of music and art. He listened to Indian classical music. Bought painting and sculptors.
L) Which event was Bhaba scheduled to attend when he met a fatal plane crash?
A) He was on his way to Vienna to attend a meeting of the scientific advisory council of the International Atomic Energy Agency.
M) When Bhabha went to England to pursue higher studies what condition did his father put on his coice of subject?
A) He told that Bhaba must finish his Mechanical engineering to further his studies in Physics.
n) Note contributions of Ernest Rutherford
A) He contributed in the field of nuclear physics. He is known as the father of nuclear physics.
o) What was the chief contribution of Carl David Anderson?
A) He discovered Positive electron or positron providing conclusive confirmation of relativistic electron theory postulated by Paul Dirac.
P) Who was Dirac? What was his major contributions?
A) Dirac was Bhabha’s Mathematics teacher. His contributed for semina work on quantum theory.
