He also invented Crescograph used for measuring the growth of plants.

6. Meghnad Saha

Meghnad Saha

Invention: Saha Ionization Equation

Meghnad Saha was an Indian scientist who missed winning the Nobel Prize in 1930.

His Saha Ionization Equation is used to draw a nearly complete picture of chemical composition and physical condition of stars, comets and other cosmic bodies.

His complex equation continues to be used till date, as scientists around the world look for planets that could potentially host alien life forms.

Summing It Up

There are several more inventions that can rightly be credited to Indian scientists.

Prime among these is Vimana or the ancient flying machine that many consider as merely mythical.

However, reliable ancient texts do prove that ancient Indians made flying machines. Ancient carvings and paintings depict these aircraft.

Further, there is evidence to prove that nuclear weapons were first used in India.

Graphic yet poetic descriptions of “Divine Weapons” used by Indian gods have an uncanny resemblance to those used in the modern world.

In recent years, India lost out on several pioneering inventions due to rampant brain drain: highly qualified and innovative scientists left the country for Europe and North America to seek fortunes. This brain drain cost India dearly.

In Conclusion

These 13 Indian Scientist and their Inventions prove that Indians have been at forefront of science and technology since times immemorial.

There are countless Indian inventions that await proper documentation.

Unfortunately, years of colonial rule and destruction of evidence by foreign rulers may mean, these pioneering inventions remain unknown to the world.
