Acharya Kanad was born in 600Bc in Dwarika,Gujrat. His real name was Kashyap. His father “Ulka” was a great philosopher. Since childhood he was attracted by minute things, particles etc.
Once he went to Prayag on a pilgrimage, he saw thousands of pilgrims littered the town roads & the banks of river Ganga with flowers and rice grains which they offered at the temple. He started collecting the grains of rice. Everybody thought he was insane as he was from a good family. Crowd gathered around him & one person asked him why was he collecting the grains even beggars wouldn’t like to touch these. He told them howsoever small the object could be, It’s a part of the universe. Individual grain might seem useless but the collection could serve as someone’s meal.” since then people started calling him “Kanad”, as “Kan” in Sanskrit means “Smallest particle” like grains.
Kanad first introduced the world about atoms and molecules. He said,”Every object of creation is made of atoms which in turn connect with each other to form molecules.” He found out universe is made up of “kana” means atoms. He studied atomic theory and found the way atoms move & react with each other. He wrote a book on his research “Vaisheshik Darshan”.
People started calling him “Acharya– the teacher”, hence the name Acharya Kanad. Acharya Kanad is known as “The Father of Atomic theory.”
