The first Friday in May is celebrated as the National Space Day across the country. The day marks the influence of science, mathematics, engineering, and technology in the efforts of space exploration. India has been one of the front runners when it comes to space exploration and technology. Being one of the few countries with launching capabilities, India has always challenged the norms and proven its proficiency in space exploration to the world. Be it cost-effective missions like the Mangalyaan or setting world records in the number of satellites launched, India is a hub for space tech.

National Space Day seeks to inspire the youth to take up higher education and pursue careers in the four fundamental fields that lend to space exploration, namely, science, mathematics, technology, and engineering. The Indian nation has also produced phenomenal personalities in these fields and here are some personalities from whom you can draw inspiration to pursue your space dreams.


Srinivasa Ramanujan

When we talk about Indian Mathematics, Ramanujan is the first name that comes to mind. He is a very unique mathematician in his right as he had no formal education. Without a degree, it is surprising how he discovered some of the most intricate theories like the Ramanujan theta function and the mock theta functions. Ramanujan is widely known for his quick solutions to complex problems. Having no formal education, Ramanujan had a difficult time proving his theories until he started a postal relationship with leading British mathematician, G. H. Hardy. Hardy later invited Ramanujan to England where he further proved and invented new theories. Hardy once noted that the solutions that Ramanujan gave had often more than what met the eye. Ramanujan often attributed his mathematical genius to his household deity Namagiri. He is one of the youngest fellows of the Royal Society and is the first Indian to be elected as the Fellow of the Trinity College, Cambridge. Sadly, Ramanujan did not stay with us for a long time and in 1920 he passed away at the age of 32.


One of the most renowned mathematicians, Aryabhata is one of the most familiar ancient Indian mathematicians. Born in 476 CE, Aryabhata gained most of his education from the Nanda University which was the international hub for knowledge at his time. Aryabhata developed the theories of the Greeks and Mesopotamians coming up with groundbreaking discoveries in Mathematics and Astronomy. His mathematical works cover algebra, arithmetics, plane trigonometry, and spherical trigonometry. Aryabhatia, his work on mathematics is a literature that has survived to modern times.

P. C. Mahalanobis

Prasanta Chandra Mahalanobis, a Bengali mathematician, and statistician are renowned for his work in Statistics and Anthropometry. His most renowned contribution to statistics is the Mahalanobis distance that gives the measure of how far a point P is from a distribution D. Mahalanobis is the founder of the Indian Statistical Institute and contributed heavily to the design of large-scale sample surveys. For his contribution, P. C. Mahalanobis is considered the father of Indian Statistics.

D. R. Kaprekar

Recreational Mathematics is a branch that focuses on utilizing mathematics for entertainment. As unusual as it sounds, D. R. Kaprekar is regarded as one of the best recreational mathematicians worldwide. He had no postgraduate education, worked as a school teacher, and worked largely alone. Some of his most notable works include Karpekar’s constant and he has described several classes of natural numbers like Karpekar, Harshad, and self numbers.

Bhaskara II

Born in Bijapur, Karnataka, Bhaskara II or Bhaskaracharya is probably the greatest Indian mathematician of ancient times. His work Siddhanta Shiromani (Crown of Treatises) laid the foundation for future works in many theories like arithmetic, algebra, spheres, and even the mathematics of planets. He is widely believed to be the first to conceive differential coefficient and differential calculus, centuries before Newton and Leibnitz.


Satyendra Nath Bose

A powerhouse in theoretical physics, Satyendra Nath Bose is one of the most prominent physicists that India produced. His work in quantum mechanics is unparallel and he collaborated with Albert Einstein to produce the Bose-Einstein Statistics and the Bose-Einstein Condensate, the fifth form of matter. Paul Dirac named particles that obey the Bose-Einstein statistics as Bosons in Satyendra’s honor. He was awarded the Padma Vibhushan by the Government of India in 1954.

C. V. Raman

A prestigious student, C. V. Raman is a world-renowned physicist most popular for his discovery of a new scattering light effect or the Raman effect, named after him. But Raman was not just involved in Physics, he was also a prolific scientist in music. He worked out theories like the theory of transverse vibration of bowed string instruments and the wolf tones of violins and cellos. He received the Nobel Prize in Physics for the Raman effect and was the first Asian to do so.

Sir Jagdish Chandra Bose

The Bengali science fiction writer, Sir Jagadish Chandra Bose is one of the greatest contributors to the field of radio and microwave optics and plant science. He was a pioneer in the first two fields and also laid the foundations for experimental research in India. He invented the crescograph, a device for measuring the growth of plants. He was given the title of Knight Bachelor in 1917 and even has a moon crater named after him.

Asima Chatterjee

The first woman to receive a Doctorate in Science from an Indian University, Asima Chatterjee was an Indian organic chemist noted for her work in organic chemistry and phytomedicine. She has authored numerous works on medicinal plants found in the Indian subcontinent. Her most prominent contributions included works on vinca alkaloids, the development of anti-epileptic drugs, and the development of anti-malaria drugs. In 1975, she was conferred the Padma Bhushan for her contributions and even nominated to the Rajya Sabha by the President from 1982 to 1990.

Mangala Mani

What Mangal Mani has achieved for science can be done only by a few. Mangala Mani, a woman scientist of ISRO (Indian Space Research Organization) is the first Indian woman to stay in Antarctica for more than a year (403 days). She had been posted to the ISRO post in Antarctica, Bharati in November 2016 and stayed there for over a year. She had never experienced snowfall in her life and carried loads of equipment to do her research work. Truly an example of the grit in Indian women to succeed.
