Dr. A. P. J. Abdul Kalam was one of the most respected scientists in India. He was born on 15 October 1931 in Rameswaram, Tamil Nadu. He played an important role in India's missile and space programmes.

He was popularly known as the Missile Man of India because of his contributions to missile development. He also worked with the Indian Space Research Organisation (ISRO) and the Defence Research and Development Organisation (DRDO).

In 2002, he became the 11th President of India. He was also a great teacher and inspired students to dream big and work hard. He received the Bharat Ratna, India's highest civilian award, in 1997.

Dr. Kalam passed away on 27 July 2015 while delivering a lecture to students. His life continues to inspire young people across the country.

2. Dr. C. V. Raman

Dr. Chandrasekhara Venkata Raman was a great Indian physicist. He was born on 7 November 1888 in Tiruchirappalli, Tamil Nadu.

He is famous for discovering the Raman Effect, which explains how light changes when it passes through a transparent material or interacts with molecules.

For this discovery, he received the Nobel Prize in Physics in 1930. He was the first Asian scientist to receive a Nobel Prize in the sciences.

National Science Day is celebrated in India on 28 February every year to commemorate the discovery of the Raman Effect. Dr. Raman's work brought international recognition to Indian science.

3. Dr. Homi Jehangir Bhabha

Dr. Homi Jehangir Bhabha was a famous Indian nuclear physicist. He was born on 30 October 1909 in Bombay, now Mumbai.

He is widely known as the Father of the Indian Nuclear Programme. He played a major role in developing scientific research and nuclear science in India.

He founded the Tata Institute of Fundamental Research (TIFR) in 1945. He also helped establish the foundations of India's nuclear energy programme.

Dr. Bhabha believed that science and technology were essential for India's development. His efforts helped India become a centre for advanced scientific research.

4. Dr. Vikram Sarabhai

Dr. Vikram Sarabhai was a great Indian scientist and visionary. He was born on 12 August 1919 in Ahmedabad, Gujarat.

He is widely regarded as the Father of the Indian Space Programme. He understood that space technology could help India improve communication, education, weather forecasting, and national development.

He played a leading role in establishing the Indian National Committee for Space Research, which later developed into the Indian Space Research Organisation (ISRO).

Dr. Sarabhai encouraged young scientists to explore new ideas and work towards the country's progress. His vision laid the foundation for India's achievements in space science.

5. Sir Jagadish Chandra Bose

Sir Jagadish Chandra Bose was an Indian scientist known for his pioneering work in physics and plant physiology. He was born on 30 November 1858 in Mymensingh, which is now in Bangladesh.

He conducted important experiments on radio waves and contributed to the development of early wireless communication research.

He also studied how plants respond to different kinds of stimuli. He invented an instrument called the crescograph to measure plant growth.

His research showed that plants respond to their surroundings in measurable ways. Jagadish Chandra Bose was a pioneer whose work influenced several areas of scientific research.

6. Dr. Satyendra Nath Bose

Dr. Satyendra Nath Bose was a renowned Indian physicist. He was born on 1 January 1894 in Calcutta, now Kolkata, West Bengal.

He made important contributions to quantum physics, a branch of science that studies the behaviour of matter and energy at very small scales.

His work on particle statistics became the foundation of what is now known as Bose-Einstein statistics. The class of particles called bosons is named in his honour.

His research influenced the development of modern physics. His work also contributed to the scientific ideas that later led to the discovery of the Bose-Einstein condensate.

Dr. Bose remains one of India's most celebrated theoretical physicists.

7. Dr. Srinivasa Ramanujan

Dr. Srinivasa Ramanujan was a brilliant Indian mathematician. He was born on 22 December 1887 in Erode, Tamil Nadu.

Although he had limited formal training in advanced mathematics, he developed extraordinary mathematical ideas through independent study.

He made important contributions to number theory, infinite series, continued fractions, and mathematical analysis.

His work attracted the attention of the British mathematician G. H. Hardy, who invited him to Cambridge University in England. Together, their collaboration produced important mathematical results.

Ramanujan's life is an inspiring example of natural talent, curiosity, and dedication. India celebrates National Mathematics Day on 22 December, his birth anniversary.

8. Dr. M. S. Swaminathan

Dr. Monkombu Sambasivan Swaminathan was a renowned Indian agricultural scientist. He was born on 7 August 1925 in Kumbakonam, Tamil Nadu.

He played a leading role in India's Green Revolution, which helped increase food grain production through improved crop varieties and better agricultural practices.

His work focused on improving food security and helping farmers increase agricultural productivity.

He worked with other scientists and agricultural experts to introduce high-yielding wheat varieties and promote modern farming methods in India.

Dr. Swaminathan received the Bharat Ratna in 2024, after his death. He is remembered for his contributions to agriculture, food security, and farmers' welfare.

9. Dr. Venkatraman Ramakrishnan

Dr. Venkatraman Ramakrishnan is an Indian-born scientist known for his important research in molecular biology and biochemistry.

He was born in Chidambaram, Tamil Nadu, on 16 April 1952. His research focused on the structure and function of ribosomes, which are tiny structures inside cells that help produce proteins.

In 2009, he shared the Nobel Prize in Chemistry with Thomas A. Steitz and Ada E. Yonath for their studies of the structure and function of the ribosome.

His research has helped scientists understand how cells produce proteins and how certain antibiotics work.

His achievements demonstrate the importance of scientific curiosity, careful research, and international collaboration.

10. Dr. Tessy Thomas

Dr. Tessy Thomas is a distinguished Indian scientist who has made significant contributions to India's missile development programme.

She worked with the Defence Research and Development Organisation (DRDO) and became known for her contributions to the Agni missile programme.

She has often been referred to in the media as the Missile Woman of India. She served as Project Director for the Agni-IV missile and contributed to the development of advanced missile technology.
