JAGADISH CHANDRA BOSE
What happens if you take a
rich magistrate's son and make him learn in a village school sitting besides
the sons of servants and fishermen? He'll hear tales of birds and animals that
make him curious about Nature. And that makes him one of India's first scientists
- Jagdish Chandra Bose.
Botanist and
physicist Jagadish Chandra Bose was born in Mymensingh, India (now in
Bangladesh) on November
30, 1858. He was educated first at the village school in Faridpur, where his
father was a magistrate, Bhagwan Chandra Bose. Later he migrated to St.
Xavier’s College, Calcutta at the age of thirteen. There he met Father Eugene Lafont, who was very interested
in promoting modern science in India. He later went to the UK, where he got
degrees from the universities of Cambridge and London. He also met Prafulla
Chandra Ray, another pioneer of Indian science.
He came back and was made a
Professor of Physics at Presidency College on the Viceroy's recommendation.
However, the principal and other faculty, who were White, were very racially
biased against him and gave only an acting appointment. He was offered
one-third the salary of the school's white professors, and in protest at this
slight he took no salary at all for several years. They denied him any laboratory facilities, but he carried on
his research work, buying equipment with his own salary.
He remained at Presidency for his entire career, where he
assembled the first modern scientific research facilities in Indian academia.
He conducted landmark research of the response of plant and animal life to
stimuli including electricity, light, sound, and touch, and showed how water
and sap in plants and trees is elevated from roots due to capillary action. He
invented the crescograph, an early oscillating recorder using clockwork gears
to measure the growth and movements of plants in increments as small as
1/100,000 of an inch. His 1902 paper "Responses in the Living and
Non-living" showed that plant and animal tissues share a similar
electric-impulse response to all forms of stimulation, a finding which
challenged conventional science of the time, and also showed that even
inanimate objects — certain rocks and metals — have similar responses. In a
1907 paper Bose established the electro transmission of excitation in plant and
animal tissues, and showed that plants respond to sound, by growing more
quickly in an environment of gentle speech or soft music, and growing more
poorly when subjected to harsh speech or loud music.
Prior
to his plant and animal experiments, Bose spent several years experimenting
with electromagnetic waves, and conducted successful wireless signaling
experiments in Calcutta in 1895. The invention of radio is usually credited to G. Marconi, but a comparison
of their records suggests that at certain points of Bose's radio research, he
was about a year ahead of the Italian scientist. In Marconi's first wireless
trans-oceanic transmission in 1901 a mercury auto coherer was a key component
of the receiving device, and while Marconi made no acknowledgment of Bose at
the time, subsequent research has shown that Marconi's auto coherer was a
near-exact replica of a mechanism invented by Bose, who explained it in detail
in a demonstration at the Royal Society of London two years earlier.
Bose
was the first Indian scientist to be widely respected as an equal in the halls
of western science. When he demonstrated his mechanisms for generating and
detecting radio waves in a January 1897 lecture before the Royal Institution in
London, it was the first such lecture given by an Indian. He was elevated to
knighthood in 1917, and in 1920 he became the first Indian elected to
membership in the prestigious Royal Society. Bose, who came from a fairly
affluent family, had no particular interest in the profit potential of his
work, and refused to file patent claims. A patent was filed by friends in
Bose's name for his 1901 invention of a solid-state diode detector to detect
electromagnetic waves.
He founded the Bose Research Institute in Calcutta in 1917,
which continues to conduct scientific research. He was a contemporary and
friend of the poet Rabindranath
Tagore. In 1937, Dr. Jagdish Chandra Bose breathed his last. In the pages
of history are recorded the glorious achievements of many great men whom the
world recognises, loves and respects. Such men prove to be a true asset not
only to their own countries but also to the world. Their lives become a message
and a source of inspiration for generations to come.
Dr. Jagdish Chandra Bose was one such personality who became
immortal in the field of science. He was not only a scientist par excellence,
but also a warm human being and a modest personality. Dr. Jagdish Chandra Bose
was worthy and illustrious son of our motherland whom the nation feels proud
of. He brought various laurels to our country. Immense hard working capacity,
patience and simplicity were hallmarks of his personality. Dr. Jagdish Chandra
Bose was a creative and imaginative scientist, a connoisseur of literature and
a great lover of nature.
Homi Jehangir Bhabha
Homi Jehangir Bhabha was a multifaceted
personality - scientist, visionary
and institution builder. He was born on October 30, 1909 in an
illustrious family with a long tradition of learning and service to the
country. Bhabha was exposed to fine arts, music and painting, which moulded his
artistic traits.
Bhabha was intelligent, hard working and
sincere student. After finishing schooling, Bhabha’s parents sent him to
Cambridge University, UK for higher education in mechanical engineering. After
completing his degree in 1932, Bhabha continued his research at Cambridge
University. His first paper appeared in 1934, based on theoretical explanation
of shower production in cosmic rays. His name is associated with Bhabha
scattering, which involves relativistic exchange scattering of electrons and
Bhabha-Heitler theory, dealing with production of electron and positron showers
in cosmic rays. Thus, it was no surprise that at a young age of 31, he
was elected as a fellow of the Royal Society, London. Bhabha rubbed shoulders
with great physicists like Bohr, Pauli, Dirac, Cockcroft and others, who
later became Noble Laureates.
This period was crucial for Bhabha for capacity building and leadership qualities.
Bhabha was on vacation during 1939, when
the second world war broke out and he could not go back abroad to
continue his research. He then joined Indian Institute of Science, Bangalore as
a Reader in Department of Physics, headed by Sir C. V. Raman and set
up a cosmic ray research unit. Raman had great admiration for Bhabha and
at Nagpur Indian Academy meeting in 1941, while introducing Bhabha, he said “Bhabha is a great lover of music,
a gifted artist, a brilliant engineer and an outstanding scientist. He is the
modern equivalent of Leonardo da Vinci”. It was from Bangalore in 1944, Bhabha wrote his historical letter
to the Tata trust for support in setting up a centre for research work in
nuclear science, which could play a central role in the development of nuclear
energy. There was a clear similarity in vision between the great Jamshedji
Nusserwanji Tata and Bhabha with respect to the need for education, scientific
research and human resource development for economic prosperity. Subsequently,
in 1945 Tata Institute of Fundamental Research (TIFR) was formed and large
scale research in physics, chemistry, electronics and mathematics
commenced.
Bhabha was instrumental for the formation of
Atomic Energy Commission in 1948 and the Department of Atomic Energy in 1954
and he chalked out a focussed research and minerals exploration programmes for
nuclear energy. He was such a visionary that he had realized the importance of
nuclear power programme way back in 1950s and enunciated a three stage nuclear
programme so as to meet the energy security of the nation. It consisted
of utilization of natural uranium, plutonium and abundant thorium resources in thermal,
fast and advanced nuclear reactors with closed fuel cycle. He also had
balanced perspective on the role of other energy resources such as coal, oil
and solar. A significant factor that contributed for the growth of nuclear
sciences and its applications was Bhabha's rapport with the then Prime Minister
Pandit Jawaharlal Nehru, who reposed complete confidence in him. This was possible because Bhabha had
the deserving credentials and his passion matched with Nehru’s vision of modern
India. There was a great synergy in thinking between Nehru and Bhabha with
respect to industrialization and scientific research, evolving hand-in-hand.
Bhabha gave utmost importance to the
development of quality human resources. The commencement and continuation of
BARC Training School for the scientific manpower over the last 50 years is a
real tribute to Bhabha’s foresight on quality manpower. Bhabha, a
person of perfection, purpose and excellence, ensured these qualities in all
his endeavours viz., research, management, buildings and environment. His total
conviction, never-accepting mediocrity, never compromising on excellence,
meeting the challenges head-on with confidence made him a unique personality.
Bhabha was a great scientific manager and followed the mantra of right man for
the right job.
Bhabha had received many prestigious national
and international awards and recognitions. In 1954, he was conferred with Padma
Bhushan award for outstanding contributions to nuclear science. In 1955, he was
elected as the President of the first International Conference on the 'Peaceful Uses of Atomic Energy',
organized by the UN at Geneva.
At a young age of 56, Bhabha suddenly passed away in 1966 due to a
plane crash in Switzerland. A vibrant and robust organization, that he had left behind with
many signal achievements in nuclear science and technology as well as a
dedicated and talented pool of human resources, bears testimony to the visionary
zeal of Bhabha. His life was an example for all of us, which stood for ‘deserve, desire and demonstrate’.
Message
for youth
Bhabha’s life is an example of pursuing individual
passion with a national perspective and purpose. If he chose, he could have
gone abroad after the Second World War and pursued his scientific research and
perhaps, could have even won Noble prize in physics. But, he chose to stay back
to serve the country. He channelized all his scientific pursuits to develop
scientific institutes with an aim to serve the society. He blended his
individual vision and passion with that of the Country. Today, we have
world class institutes and the Departments like Atomic Energy and Space, thanks
to Bhabha’s foresight and vision. Thus, his life message to all of us is ‘do pursue the passion of
your life but with a vector or direction of serving the country and making it
proud with your contributions’.
VIKRAM SARABHAI
Vikram Sarabhai was one of the greatest scientists of India.
He is considered as the Father of the Indian space program. Apart from being a
scientist, he was a rare combination of an innovator, industrialist and
visionary.
Vikram Ambalal Sarabhai was born on August 12, 1919 at
Ahmedabad in an affluent family of progressive industrialists. He was one of
eight children of Ambalal and Sarla Devi. He had his early education in a
private school. Some of the great men of India such as Rabindranath Tagore, Jawaharlal Nehru, Sarojini Naidu, Maulana
Azad, C. F. Andrews, Sir C. V. Raman
used to stay with the Sarabhai family when they visited Ahmedabad. Mahatma
Gandhi also once stayed at their house while recovering from an illness. Visits
by such great men greatly influenced Vikram Sarabhai.
After his matriculation, Vikram Sarabhai proceeded to
Cambridge for his college education and took the tripos in Natural Sciences
from St. John's college in 1940. When World War II began, he returned home and
joined as a research scholar under Sir C. V. Raman at the Indian Institute of
Science, Bangalore. His interest in solar physics and cosmic ray led him to set
up many observation stations around the country. He built the necessary
equipment with which he took measurements at Bangalore, Poona and the
Himalayas. He returned to Cambridge in 1945 and completed his Ph.D in 1947.
Vikram Sarabhai was instrumental in establishing the Physical
Research Laboratory (PRL) in Ahmedabad in November 1947. The laboratory was
established in a few rooms in M.G. Science Institute of the Ahmedabad Education
Society, which was founded by his parents. Subsequently, it got support from
the Council of Scientific and Industrial Research (CSIR) and the Department of
Atomic Energy.
Vikram Sarabhai did research on the time variations of cosmic
rays and concluded that meteorological effects could not entirely affect the
observed daily variations of cosmic rays; further, the residual variations were
wide and global and these were related to variations in solar activity. Vikram
Sarabhai visualized a new field of research opening up in solar and
interplanetary Physics.
The year 1957-1958 was designated as International
Geo-physical year (IGY). The Indian program for the IGY had been one of the
most significant ventures of Sarabhai. It exposed him to the new vistas of
space science with the launching in 1957 of Sputnik-I. Subsequently, the Indian
National Committee for Space Research was created, of which Vikram Sarabhai
became Chairman.
With active support from Homi Bhabha, Vikram Sarabhai, set up
the first Rocket Launching station (TERLS) in the country at Thumba near
Thiruvananthapuram on the Arabian Coast, as Thumba is very close to the
Equator. The first rocket with sodium vapour payload was launched on November
21, 1963.
As a result of Dr. Sarabhai's dialogue with NASA in
1966, the Satellite Instructional Television Experiment (SITE)
was launched during July 1975 – July 1976 (when Dr. Sarabhai was no more). Dr.
Sarabhai started a project for the fabrication and launch of an Indian satellite. As a result, the first Indian satellite, Aryabhata, was put
in orbit in 1975 from a Russian Cosmodrome.
After the sudden death of Homi Bhabha in an air crash, Vikram
Sarabhai was appointed Chairman, Atomic Energy Commission in May 1966. He
wanted the practical application of science to reach the common man. He decided
to acquire competence in advance technology for the solution of country’s
problems based on technical and economic evaluation of its real resources. He
initiated India’s space programme, which today is renowned all over the world.
To train efficient managers of factories, he started the
Indian Institute of Management (IIM) at Ahmedabad. Of all the institutions, he
established the most important were the ‘Indian Space Research Organization’
with Centers at Thumba, Ahmedabad, Shriharikota and Arvi. He established Rocket
Launching Stations at Thumba and Shrihatikota. Along with his work on the
science front, he took utmost interest and managed family business of Textiles
and Pharmaceuticals. He died suddenly in 1971, aged fifty-two, at the
height of his creative career.
Dr.
Vikram Sarabhai was awarded with Shanti Swarup Bhatnagar Medal in 1962 and
Padma Bhushan in 1966. Vikram Sarabhai passed away in his sleep on December
31,1971.
