Sir C.V. Raman 

Sir C.V. Raman was an Indian physicist who made groundbreaking discoveries in the field of optics and acoustics. He is best known for his discovery of the Raman Effect, which is the scattering of light by particles in a medium. This effect is used in many applications, including cancer diagnosis and the detection of counterfeit drugs. 

Raman was born in Tamil Nadu, India in 1888. He obtained his bachelor's degree from Presidency College in Madras and went on to study physics at Cambridge University. After completing his studies, he returned to India and joined the Indian Institute of Science in Bangalore, where he worked for many years. In 1930, he was awarded the Nobel Prize in Physics for his discovery of the Raman effect. 

Raman's other notable contributions include his work on the properties of diamonds, the development of a new method for measuring air pressure, and studies on the scattering of X-rays and gamma rays. He also wrote several popular books on science, including The Nature of Light and Sound (1939) and The Physics of Solids (1945). Raman died in 1970 at the age of 82. 

Satyendranath Bose 

Satyendranath Bose was an Indian physicist who laid the foundation of modern quantum statistics. He is best known for his work on the theory of the behavior of particles that obey what is now known as Bose–Einstein statistics. 

Bose was born in Calcutta, India, on January 1, 1894. He studied physics at the Presidency College, graduating in 1915. He went on to study at the University of Calcutta and then at Cambridge University, where he worked with J.J. Thomson on the effects of electric fields on the gas of charged particles. 

In 1924, Bose published a paper deriving Planck’s law of black-body radiation without making use of classical physics. This was followed by a series of papers developing the statistical treatment of particles that obeyed what is now known as Bose–Einstein statistics. 

In 1938, Einstein invited Bose to join him at the Institute for Advanced Study in Princeton, New Jersey. Bose remained at the Institute until his death in 1975. Bose’s work laid the foundation for the development of quantum mechanics and has had applications in diverse fields such as cosmology, superfluidity, and lasers.

Meghnad Saha 

Meghnad Saha was an Indian astrophysicist who developed the ionization equation, which is used to determine the conditions under which a star produces energy. He also did important work on the theory of stellar spectra and on the identification of elements in stars. 

Homi J. Bhabha 

Homi Jehangir Bhabha FRS was an Indian nuclear physicist, founding director, and professor of physics at the Tata Institute of Fundamental Research. Colloquially known as "Father of the Indian Bomb", he played a pivotal role in the development of India's nuclear program. 

Bhabha received his early education at the Cathedral and John Connon School, Mumbai and Elphinstone College, Mumbai. He then went on to study for one year at Royal Institute of Science in Mumbai before going to Cambridge University on an India Association Scholarship in 1934. There he gained his tripos in physics with first class honours and excelled in Mathematics gaining a first class honours degree. After completing his studies at Cambridge, Bhabha joined CERN on Rutherford’s recommendation as Assistant Professor. 

In 1945, Bhabha was elected Fellow of the Royal Society. In 1957, he founded TIFR which has since emerged as one of India's leading scientific research institutions. Some of Bhabha's major achievements include his work on Compton scattering, his theory of cosmic rays, and his prediction of the pion-zero meson or pi-meson which later came to be known as the "Higgs boson".

Subrahmanyam Chandrashekhar

Subrahmanyam Chandrashekhar was an Indian-American astrophysicist who made groundbreaking contributions to the field of stellar evolution. He is best known for his work on the Chandrasekhar limit, which is the maximum mass of a white dwarf star. 

Chandrashekhar was born in Lahore, India in 1910. He attended Presidency College in Madras, where he studied physics under the renowned scientist C.V. Raman. After graduating from college, Chandrashekhar won a scholarship to study at Trinity College, Cambridge. It was there that he developed an interest in stellar evolution and came up with the idea for the Chandrasekhar limit.

Chandrashekhar returned to India in 1930 and began teaching at the University of Allahabad. In 1935, he published his first paper on the subject of white dwarf stars, which outlined his theory on the Chandrasekhar limit. This work earned him international recognition and he was awarded the Nobel Prize in Physics in 1983. 

Chandrashekhar made many other important contributions to astrophysics during his career. He helped develop theories on the formation of planetary nebulae and black holes. He also did pioneering work on computer simulations of stellar collisions. Chandrashekhar died in 1995 at the age of 84. 

Vikram Sarabhai

Vikram Sarabhai was an Indian physicist who is considered to be the father of India's space program. He was born in Ahmedabad, Gujarat in 1919. After studying physics at Cambridge University, he returned to India and founded the Physical Research Laboratory in 1947. He played a key role in the establishment of the Indian Institute of Management Ahmedabad and the Vikram A Sarabhai Community Science Centre.

Sarabhai's contributions to science were many and varied. He helped develop nuclear power for India, and also worked on applications of cosmic rays and upper atmospheric research. He was instrumental in setting up India's first Satellite Telecommunication Earth Station and launching its first satellite, Aryabhata. He also founded the Indian Space Research Organisation (ISRO) in 1969.

Sarabhai received many awards during his lifetime, including the Padma Bhushan (1966) and the Padma Vibhushan (1972). He died suddenly in 1971, aged 52, but his legacy continues through ISRO and its many successes, including the launch of India's first moon mission, Chandrayaan-1, in 2008. 

G.N Ramachandran 

G.N Ramachandran was an Indian physicist who made significant contributions to the fields of physics and chemistry. He is best known for his work on the structure of proteins, which led to the discovery of the alpha helix. He also contributed to the understanding of sickle cell disease and developed a model for DNA that provided insight into how it could store information.

Jayant Narlikar 

Jayant Narlikar is an Indian astrophysicist and cosmologist who worked with Fred Hoyle. He is known for his contributions to the field of cosmology and his advocacy of the steady state theory. He has also worked on theories of gravitation and the origin of cosmic rays.

He is a recipient of the Padma Bhushan, Padma Vibhushan, and the prestigious Kalinga Prize for Science. He was also awarded the Gold Medal by the Royal Astronomical Society in 1981 and the Dirac Medal by UNESCO in 1985. He has served as Professor Emeritus at the Inter-University Centre for Astronomy and Astrophysics in Pune, India. 

Narlikar is credited with work on Mach's principle, which suggests that inertia may be a consequence of distant matter in the universe, and describes its relation to gravity. This work has been used to explain certain cosmological phenomena such as cosmic inflation and dark energy. He is also known for his contributions to black hole thermodynamics, which led to a better understanding of quasars. 

Narlikar is considered one of India's foremost astrophysicists and cosmologists and has written extensively on topics related to astrophysics and cosmology. His popular books include The Primeval Universe (1986), Modern Cosmology (1989), Quasars (1990) and The Structure of the Universe (1998). 

Harish Chandra 

Harish Chandra was an Indian physicist who made significant contributions to the fields of quantum electrodynamics and representation theory. He is best known for his work on the mathematical model of the hydrogen atom, which led to the development of the atomic bomb. 

Born in Lahore in 1911, Chandra was educated at the University of Cambridge, where he worked with some of the leading physicists of his time, including Niels Bohr and Paul Dirac. After returning to India, he taught at the Allahabad University and then at the Indian Institute of Technology, Kanpur. 

Chandra's work on quantum electrodynamics was instrumental in developing the theory of renormalization, which is widely used in physics today. He also did important work on representation theory, which is a branch of mathematics that studies symmetry in physical systems. Chandra was awarded the Nobel Prize in Physics in 1970 "for his outstanding contributions to theoretical physics". He died in 1971 at the age of 59.
