3. • Science and Technology have always been an
integral part of Indian culture.
• Natural philosophy, as it was termed in those ancient
times, was pursued vigorously at institutions of
higher learning.
• The Indian Renaissance, which coincided with our
independence struggle, at the dawn of 1900s
witnessed great strides made by Indian scientists.
• This innate ability to perform creatively in science
came to be backed with an institutional setup and
strong state support after the country’s
independence in 1947.
• Since then, the Government of India has spared no
effort to establish a modern S&T infrastructure in the
country.
• The Department of Science and Technology plays a
pivotal role in promotion of science and technology in
the country.
Science & Technology

4. C.V.RAMAN
Sir Chandrasekhara Venkata Raman was an
Indian physicist.
Born in the former Madras Province in India presently called
as Tamil Nadu.
He carried out ground-breaking work in the field of light
scattering.
Raman discovered that when light traverses a transparent
material, some of the deflected light changes wavelength.
This phenomenon, subsequently known as Raman scattering,
results from the Raman effect.
INTRODUCTO
N

5. At an early age, Raman moved to the city of Visakhapatnam and
studied at St. Aloysius Anglo-Indian High School.
Raman passed his matriculation examination at the age of 11
and he passed his F.A. examination with a scholarship at the
age of 13.
In 1902, Raman joined Presidency College in Madras where his father
was a lecturer in mathematics and physics In 1904
In 1907 he gained his Master of Sciences degree with the
highest distinctions from University of Madras
He stood first and won the gold medal in physics..

6. In the year 1917, Raman resigned from his government service after he was
appointed the first Palit Professor of Physics at the University of Calcutta.
At the same time, he continued doing research at the Indian
Association for the Cultivation of Science (IACS).
Raman discovered a phenomena on scattering of light
,which he named “RAMAN’S EFFECT”
Raman had a complicated professional relationship
with K. S. Krishnan.
Raman and Krishnan shared a noble prize in
physic
CARRER

7. During a voyage to Europe
in 1921, Raman noticed the
blue colour of glaciers and
the Mediterranean sea. He
was motivated to discover
the reason for the blue
colour.
ACHIVEMENTS
. Raman carried out
experiments regarding the
scattering of light by water and
transparent blocks of ice which
explained the phenomenon.. He
detected lines in the spectrum,
which were later called Raman
lines
He presented his theory at a
meeting of scientists in
Bangalore on 16 March
1928, and won the Nobel
Prize in Physics in 1930.
. In Munich, some physicists
were initially unable to
reproduce Raman's results,
leading to scepticism.

8. Awards and Honours of
C.V Raman
• Professor C V Raman was also the first to
investigate the harmonic nature of the sound
• Raman was also conferred the title of ‘Bharat Ratna'
in 1954.
• C.V’s discovery of the ‘Raman Effect' made a very
distinctive contribution to Physics.
• In 1943, he established the ‘Raman Research
Institute', near Bangalore. Bangalore.
• Highest honour in science, the ‘Nobel Prize' in
physics.

9. Homi JehangirBhabha
Indian development of nuclear weapons which Bhabha
also supervised as its director
INTRODUCTION
Homi Jehangir Bhabha (30 October 1909 – 24 January
1966) was an Indian nuclear physicist.
Baba was founding director, and professor of physics at
the Tata Institute of Fundamental Research.
Colloquially known as "father of the Indian nuclear
programme’.
Baba was the founding director of two well-known
research institutions, namely the Tata Institute of
Fundamental Research and the Trombay Atomic
Energy

10. After completing his Mechanical
engeneering he joined Tata Steel.
Early Life
Homi Jehangir Bhabha was born
into a wealthy and prominent
industrial Parsi family.
He received his early education
at Bombay's Cathedral and John
Connon School.
Baba joined Elphinstone college,
then he passed his Cambridge
examination
He then attended the Royal
Institute of Science until 1927
Then be joined Caius
College of Cambridge University.

11. Starting his nuclear physics career in Britain, Bhabha had returned
to India for his annual vacation before the start of World War II in
September 1939.
Bhabha played a key role in convincing the Congress Party's senior
leaders.
Bhabha established the Cosmic Ray Research Unit at the Institute,
began to work on the theory of point particles movement.
In 1945, he established the Tata Institute of Fundamental
Research in Bombay, and the Atomic Energy.

12. ATOMIC ENERGY IN INDIA
• Homi bhaba is known as the father of atomic science in
India
• With the help of trustees he established an atomic
research at Mumbai
• Many radioactive substances were discovered at this
atomic plant
• After , his death the atomic center was named after him

13. LEGECY OF HOMI BABA
After his death, the Atomic Energy Establishment
at Bombay was renamed as the Bhabha Atomic
Research Centre in his honour
Bhabha was also a painter
and a classical music and opera enthusias
and a lover of plants.
Bhabha also encouraged research in
electronics, space science, radio astronomy
and microbiology..
. The Homi Bhabha Fellowship Council has been
giving the Homi Bhabha Fellowships since 1967

14. SALIM ALI
Sálim Moizuddin Abdul Ali (12 November 1896 – 20
June 1987) was
an Indian ornithologist and naturalist.
Sometimes referred to as the "birdman of India"
Salim Ali was among the first Indians to conduct
systematic bird surveys across India .
He became the key figure behind the Bombay
Natural History Society after 1947.
Salim prevented the destruction of what is now
the Silent Valley National Park.
Intoduction

15. EARLY LIFE
Salim went to primary school at Zenana Bible
and Medical Mission High School.
Salim gained his higher education from St.
Xavier's College,
Salim was born in a Muslim Bhora
family.
He collected different types of birds.
He barely managed to pass the matriculation
exam of the Bombay University in 1913.

16. Ornithonolgy
Hugh Whistler
Ornithology is a branch of zoolgy that
concerns the study of birds.
The science of ornithology has a long
history and studies on birds .
Early ornithology was principally
concerned with descriptions and
distributions of species
Most modern biological theories apply
across taxonomic groups and the number
of professional scientists who identify
themselves as "ornithologists" .
A wide range of tools and techniques are used in
ornithology..

17. Later Life and Death:
• Salim not only researched about birds, but
also contributed to the arena of protection of
nature.
• For his extraordinary efforts, he was given
an international award of INR 5 lacs, but he
donated all the money to Bombay Natural
History Society.
• The Government of India honoured him
with Padma Vibhushan in 1983.
• This genius man died at the age of 90 on
June 20, 1987.

18. As soon as Salim returned, he studied zoology,
and secured a position of a guide at the museum
of the Bombay Natural History Society.
He published a research paper discussing the
nature and activities of the weaver bird in 1930.
Contributions and Achievements:
He published “The Book of Indian Birds in
1941” in which he discussed the kinds and
habits of Indian birds.
He got many awards and honors on
orthonology.
