India has made many significant contributions to mathematics, science, and technology over the centuries. Some key contributions include: 1) Aryabhatta invented the number system with zero and made advances in algebra, trigonometry, and calculus. 2) Bhaskaracharya calculated the time taken for earth to orbit the sun centuries before Western astronomers. 3) Sushruta is considered the father of surgery, performing complicated procedures like cesareans and cataract surgery over 2,000 years ago. 4) Figures like Raman, Bose, Bhabha, Khorana, Sen, and Chandrasekhar have won Nobel Prizes for their revolutionary work

9. chanakya is traditionally identified as Kautilya or Vishnu Gupta,
who authored the ancient Indian political treatise
called Arthaśāstra. As such, he is considered as the pioneer of
the field of economics and political science in India, and his work
is thought of as an important precursor to Classical
Economics. Chanakya is often called the
"Indian Machiavelli", although his works predate Machiavelli's by
about 1,800 years.His works were lost near the end of the Gupta
dynasty and not rediscovered until 1915.

formulation of the 3,959 rules of Sanskrit morphology, syntax
and semantics in the grammar known
as Ashtadhyayi (अष्टाध्यायी Aṣṭādhyāyī, meaning "eight
chapters"), the foundational text of the grammatical branch
of the Vedanga, the auxiliary scholarly disciplines of Vedic
religion.

16. Sir C.V.Raman
• He gave enormous contribution
in the field of vibration, sound,
musical instruments, ultrasonics,
diffraction, photo electricity,
colloidal particles, X-ray
diffraction, magnetron,
dielectrics, etc.
• He gave ‘THE RAMAN EFFECT’
regarding the scattering of the

17. J.C. BOSE Bose subsequently made a number of
pioneering discoveries in plant
physiology. He used his own invention,
the crescograph, to measure plant
response to various stimuli, and
thereby scientifically proved
parallelism between animal and plant
tissues. Although Bose filed for a
patent for one of his inventions due to
peer pressure, his reluctance to any
form of patenting was well known. To
facilitate his research, he constructed
automatic recorders capable of
registering extremely slight
movements; these instruments
produced some striking results, such
as Bose’s demonstration of an
apparent power of feeling in plants,
exemplified by the quivering of injured
plants.

18. Bhabha gained international
prominence after deriving a correct
expression for the probability of
scattering positrons by electrons, a
process now known as Bhabha
scattering. His major contribution
included his work on Compton
scatterin, R-process, and furthemore
the advancement of nuclear physics.

19. Har Gobind Khorana
Hargobind Khorana (January 9, 1922
– November 9, 2011) was a biochemist
who shared the 1968 Nobel Prize for
Physiology or Medicine with Marshall W.
Nirenberg and Robert W. Holley for
research that helped to show how
the nucleotides in nucleic acids, which
carry the genetic code of the cell,
control the cell’s synthesis of proteins.
Khorana and Nirenberg were also
awarded the Louisa Gross Horwitz
Prize from Columbia University in the
same year.

20. Amartya Sen
Amartya Sen, is an Indian economist who
was awarded the 1998 Nobel Prize in
Economic Sciences for his contributions
to welfare economics and social choice
theory. Sen is best known for his work on the

preventing or limiting the effects of real or
perceived shortages of food. Amartya Sen's

him in their 2010 edition of "World's 50 Most
Influential People Who Matter

evolutionary stages of massive stars.
The Chandrasekhar limit is named after him.
Chandrasekhar was the nephew of Sir
Chandrasekhara Venkata Raman.
Chandrasekhar worked in distinct periods
worked in various areas including stellar
structure, theory of white dwarfs, stellar
dynamics, theory of radiative transfer,
quantum theory of the negative ion of
Hydrogen

India for his work on the development of ballistic
