Acharya Kanad

The Indian Sage who developed Atomic Theory 2,600 years ago

John Dalton (1766 – 1844), an English chemist and physicist, is the man credited today with the development of atomic theory.  However, a theory of atoms was actually formulated2,500 years before Dalton by an Indian sage and philosopher, known as Acharya Kanad.

Acharya Kanad was born in 600 BC in Prabhas Kshetra (near Dwaraka) in Gujarat, India. His real name was Kashyap.

Kashyap was on a pilgrimage to Prayag when he saw thousands of pilgrims litter the streets with flowers and rice grains, which they offered at the temple. Kashyap, fascinated by small particles, began collecting the grains of rice. A crowd gathered around to see the strange man collecting grains from the street. Kashyap was asked why he was collecting the grains that even a beggar wouldn’t touch. He told them that individual grains in themselves may seem worthless, but a collection of some hundred grains make up a person's meal, the collection many meals would feed an entire family and ultimately the entire mankind was made of many families, thus even a single grain of rice was as important as all the valuable riches in this world. Since then, people began calling him ‘Kanad’, as ‘Kan’ in Sanskrit means ‘the smallest particle’. 

Kanad pursued his fascination with the unseen world and with conceptualising the idea of the smallest particle. He began writing down his ideas and teaching them to others.  Thus, people began calling him ‘Acharya’ (‘the teacher’), hence the name Acharya Kanad (‘the teacher of small particles’)

Kanad’s conception of Anu (the atom)

Kanad was walking with food in his hand, breaking it into small pieces when he realised that he was unable to divide the food into any further parts, it was too small. From this moment, Kanad conceptualised the idea of a particle that could not be divided any further. He called that indivisible matter Parmanu, or anu (atom).

Acharya Kanad proposed that this indivisible matter could not be sensed through any human organ or seen by the naked eye, and that an inherent urge made one Parmanu combine with another.  When two Parmanu belonging to one class of substance combined, a dwinuka (binary molecule) was the result. This dwinuka had properties similar to the two parent Parmanu.

Kanad suggested that it was the different combinations of Parmanu which produced different types of substances. He also put forward the idea that atoms could be combined in various ways to produce chemical changes in presence of other factors such as heat. He gave blackening of earthen pot and ripening of fruit as examples of this phenomenon.

Acharya Kanad founded the Vaisheshika school of philosophy where he taught his ideas about the atom and the nature of the universe. He wrote a book on his research “Vaisheshik Darshan” and became known as “The Father of Atomic theory.”

In the West, atomism emerged in the 5th century BC with the ancient Greeks Leucippus and Democritus. Whether Indian culture influenced Greek or vice versa or whether both evolved independently is a matter of dispute.

Kanad is reporting to have said: ”Every object of creation is made of atoms which in turn connect with each other to form molecules.”  His theory of the atom was abstract and enmeshed in philosophy as they were based on logic and not on personal experience or experimentation. But in the words of A.L. Basham, the veteran Australian Indologist, "they were brilliant imaginative explanations of the physical structure of the world, and in a large measure, agreed with the discoveries of modern physics."

The Father of Atomic Theory: Acharya Kanad – Sanskaar Varg

Ancient India’s Contribution to Physics – United India


Yeah, finally some science articles, can we have some more, please? It's obvious from the comments that lots of people on the site think this too....
If you want a hand with unravelling the mystery of Daedalus and first flight, happy to write an article for you. I'm pretty sure they got this flying, I might build a scale model as a proof of concept over a weekend. It's the same today as then, show the war chief a new technical capability and they throw a little cash at it. I know they got this working and you can build a basic glider with Minoan tech, easy peasy.

So, what we've been taught for years, that the Greeks originated the idea of atoms, is wrong? The Indians came up with it first?
"the fifth century BCE by Leucippus and Democritus. The Greeks called these particles atomos, meaning indivisible, and the modern word “atom” is derived from this term"

So Indians may have invented the idea of atomic theory but certainly missed out on the concepts of basic sanitation. Instead of creating and worshiping all those imaginary gods, they should have developed toilets and bathrooms. Here it is 2018 and Indians still defecate in public like dogs. India is a filthy, disgusting, seething cesspool of humanity and excuse for a civilized country.
