4. Satyendra Nath Bose

Satyendra Nath Bose
Born -1 January 1894
Died - 4 February 1974
He was a Bengali Indian physicist specializing
in mathematical physics. He was born
in Calcutta. He is best known for his work
on quantum mechanics in the early 1920s,
providing the foundation for Bose–Einstein
statistics and the theory of the Bose–Einstein
condensate. A Fellow of the Royal Society,
the Government of India awarded him India's
second highest civilian award, the Padma
Vibhushan in 1954.

5. Sir Chandrasekhara
Venkata Raman
Born - 7 November 1888
Died – 21 November 1970
He was an Indian physicist whose ground
breaking work in the field of light scattering
earned him the 1930 Nobel Prize for Physics.
He discovered that, when light traverses a
transparent material, some of the deflected
light changes in wavelength. This phenomenon
is now called Raman scattering and is the
result of the Raman effect. In 1954, he was
honored with the highest civilian award in
India, the Bharat Ratna.

6. Srinivasa Ramanujan
Born - 22 December 1887
Died – 26 April 1920
He was an Indian mathematician and autodidact who, with
almost no formal training in pure mathematics, made
extraordinary contributions to mathematical
analysis, number theory, infinite series, and continued
fractions. Living in India with no access to the larger
mathematical community, which was centred in Europe at
the time, Ramanujan developed his own mathematical
research in isolation. As a result, he rediscovered known
theorems in addition to producing new work. Ramanujan
was said to be a natural genius by the English
mathematician G. H. Hardy, in the same league as
mathematicians such as Euler and Gauss.

7. Homi Jehangir Bhabha
Born - 30 October 1909
Died – 24 January 1966)
He was an Indian nuclear physicist, founding
director, and professor of physics at the Tata
Institute of Fundamental Research. Colloquially
known as "father of Indian nuclear
programme”, Bhabha was the founding director
of two well-known research institutions, namely
the Tata Institute of Fundamental
Research (TIFR) and the Trombay Atomic Energy
Establishment (now named after him); both sites
were the cornerstone of Indian development of
nuclear weapons which Bhabha also supervised
as its director.

8. Subrahmanyan Chandrasekhar
Born - October 19 1910
Died – August 21 1995
He was an IndianAmerican astrophysicist who, with William A.
Fowler, was awarded the 1983 Nobel Prize for
Physics for his mathematical theory of black
holes, which was a key discovery that led to
the currently accepted theory on the later
evolutionary stages of massive
stars. The Chandrasekhar limit is named after
him.

9. Avul Pakir Jainulabdeen Kalam
Born - 15 October 1931
He usually referred to as Dr. A. P. J. Abdul Kalam, is an
Indian scientist and administrator who served as
the 11th President of India from 2002 to 2007. Kalam
was born and raised in Rameswaram, Tamil Nadu,
studied physics at the St. Joseph's College,
Tiruchirappalli, and aerospace engineering at
the Madras Institute of Technology (MIT), Chennai.
Before his term as President, he worked as an
Aerospace engineer with Defence Research and
Development Organisation (DRDO) and Indian Space
Research Organisation (ISRO). Kalam is popularly
known as the Missile Man of India for his work on the
development of ballistic missile and launch
vehicle technology. He played a pivotal organizational,
technical and political role in India's Pokhran-II nuclear
tests in 1998, the first since the original nuclear test by
India in 1974.

10. FAMOUS
SCIENTISTS
AROUND THE
WORLD

11. Albert Einstein
Born - 14 March 1879
Died – 18 April 1955
He was a German-born theoretical physicist and
violinist. He developed the general theory of
relativity, one of the two pillars of modern
physics (alongside quantum mechanics). While
best known for his mass–energy
equivalence formula E = mc2 (which has been
dubbed "the world's most famous equation"), he
received the 1921 Nobel Prize in Physics "for his
services to theoretical physics, and especially for
his discovery of the law of the photoelectric
effect”. The latter was pivotal in
establishing quantum theory.

12. Albert Einstein
Near the beginning of his career, Einstein thought
that Newtonian mechanics was no longer enough to
reconcile the laws of classical mechanics with the laws
of the electromagnetic field. This led to the development
of his special theory of relativity. He realized, however,
that the principle of relativity could also be extended
to gravitational fields, and with his subsequent theory of
gravitation in 1916, he published a paper on the general
theory of relativity. He continued to deal with problems
of statistical mechanics and quantum theory, which led
to his explanations of particle theory and the motion of
molecules. He also investigated the thermal properties
of light which laid the foundation of the photon theory of
light. In 1917, Einstein applied the general theory of
relativity to model the large-scale structure of
the universe.

13. Sir Isaac Newton
Born - 25 December 1642
Died – 20 March 1727
He was an English physicist and mathematician who
is widely regarded as one of the most influential
scientists of all time and as a key figure in
the scientific revolution. His book Philosophiæ
Naturalis Principia Mathematica ("Mathematical
Principles of Natural Philosophy"), first published in
1687, laid the foundations for most of classical
mechanics. Newton also made seminal contributions
to optics and shares credit with Gottfried Leibniz for
the invention of the infinitesimal calculus.

14. Sir Isaac Newton
Newton's Principia formulated the laws of
motion and universal gravitation that dominated scientists'
view of the physical universe for the next three centuries. It
also demonstrated that the motion of objects on the Earth
and that of celestial bodies could be described by the same
principles. By deriving Kepler's laws of planetary
motion from his mathematical description of gravity, Newton
removed the last doubts about the validity of
the heliocentric model of the cosmos.

15. Aristotle
Born - 384 BCE
Death – 322 BCE
He was a Greek philosopher born in Stagirus, northern Greece,
in 384 BCE. His father, Nicomachus, died when Aristotle was a
child, whereafter he lived under a guardian’s care. At eighteen,
he joined Plato’s Academy in Athens and remained there until the
age of thirty-seven (c. 347 BCE). His writings cover many
subjects – including physics, biology, zoology,
metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhet
oric, linguistics, politics and government – and constitute the first
comprehensive system of Western philosophy. Shortly after Plato
died, Aristotle left Athens and, at the request of Philip of
Macedonia, tutored Alexander the Great between 356 and
323 BCE. According to the Encyclopædia Britannica, “Aristotle
was the first genuine scientist in history. ... Every scientist is in his
debt.

16. Marie Curie
Born - 7 November 1867
Death – 4 July 1934
He was a Polish and naturalizedFrench physicist and chemist who conducted
pioneering research on radioactivity. She was
the first woman to win a Nobel Prize, the only
woman to win in two fields, and the only
person to win in multiple sciences. She was
also the first woman to become a professor at
the University of Paris, and in 1995 became
the first woman to be entombed on her own
merits in the Panthéon in Paris.

17. Archimedes of Syracuse
Born - 287 BC
Death – 212 BC
He was
a Greek mathematician, physicist, engineer, inventor,
and astronomer. Although few details of his life are
known, he is regarded as one of the
leading scientists in classical antiquity. Among his
advances in physics are the foundations
of hydrostatics, statics and an explanation of the
principle of the lever. He is credited with designing
innovative machines, including siege engines and
the screw pump that bears his name. Modern
experiments have tested claims that Archimedes
designed machines capable of lifting attacking ships
out of the water and setting ships on fire using an
array of mirrors.

18. Nikola Tesla
Born - 10 July 1856
Death– 7 January 1943
He was a Serbian American inventor, electrical
engineer, mechanical engineer, physicist, and futurist best known
for his contributions to the design of the modern alternating
current (AC) electricity supply system.Tesla gained experience
in telephony and electrical engineering before emigrating to
the United States in 1884 to work for Thomas Edison. He soon
struck out on his own with financial backers, setting up laboratories
and companies to develop a range of electrical devices. His
patented AC induction motor and transformer were licensed
by George Westinghouse, who also hired Tesla as a consultant to
help develop a power system using alternating current. Tesla is
also known for his high-voltage, high-frequency power experiments
in New York and Colorado Springs which included patented
devices and theoretical work used in the invention
of radio communication, for his X-ray experiments, and for his illfated attempt at intercontinental wireless transmission in his
unfinished Wardenclyffe Tower project.
