India is full of geniuses and innovators who have made us proud. Needless to say, our country's contributions to the field of science are some of the greatest. But here's the thing. Most of these scientists are either not well-known or not talked about enough. The years of hard work that these people have put in is immensely applaudable and deserves our attention.

If you haven't heard of them, here are 15 lesser-talked about Indian innovators that you must take out time to read about:

1. Yellapragada Subbarow

Even if you don't understand the technicalities, I'm sure you know what cancer is. This Indian biochemist discovered the function of adenosine triphosphate as an energy source in the cell , and developed methotrexate for the treatment of cancer! Guess who's helping us out, immensely?

2. Satyendra Nath Bose

He is 'one of those' who actually met Albert Einstein to formulate a theory related to the gas-like qualities of electromagnetic radiation! Indeed a brilliant mathematician and physicist.

8. Meghnad Saha

We may not understand the fundas behind the astrological crap we hear everyday. But this astrophysicist developed the Saha equation which explains chemical and physical cond itions in stars. It is considered as the twelfth most important landmark in the history of astronomy!

9. Har Gobind Khorana

Two words. Genetic code. He won a Nobel Prize in 1968 for his outstanding work in the field and is the first person to segregate the DNA parts and chains of nucleotides. But how many of us have heard of him?

11. Gopalaswamy Doraiswamy Naidu

How does an electric motor work? Well, because of him! He is referred to as the Edison of India and has manufactured the first electric motor in India, in 1937. But that's not all! H is other inventions include super-thin shaving blades, a distance adjuster for film cameras, a fruit juice extractor, a tamper-proof vote-recording machine and a kerosene-run fan!

12. Subrahmanyan Chandrasekhar

So he graduated with a degree in physics before reaching his twentieth birthday, is a child prodigy and The Chandrasekhar Limit is named after him! Insane right? For the bulk of work that he's done, he also won a Nobel Prize.

13. G.N.Ramachandran

Along with his major contributions in Physics and Biology, he discovered the ways to describe the 3-D structure of proteins well before the same was done with crystallography. Amazing, right? He also created the Ramachandran plot for understanding peptide structure and was the first to propose a triple-helical model for the structure of collagen .

14. Ashoke Sen

A legendary physicist of his time, he was among the first recipients of the Fundamental Physics Prize "for opening the path to the realisation that all string theories are different limits of the same underlying theory". Currently, a professor at the Harish-Chandra Research Institute , Allahabad, he is also the Morningstar Visiting Professor at MIT .

15. Aneesur Rahman

Have you heard about the Aneesur Rahman Prize for computational physics? This man has an award in his honour for being the father of molecular dynamics, a discipline of physics that utilizes computers to simulate microscopic behavior of physical systems. His study of liquid argon in 1964 started an entire field of study!

Special mention: H emendra Nath Chatterjee

We weren't aware of the Diarrhoea treatment until he showed us how. Let's remember him as the Bengali scientist who was the first to formulate and demonstrate the effectiveness of Orally Rehydrated Saline for diarrhoea management.
