so atoms are the smallest unit of matter and building blocks of everything in the universe

be it solid,liquid or gas right from the gain of sand to strand of hair to your body to the planets,stars and the moon to the infinity.

where did it all began as the story goes one fine day in ancient india maharshi kanada an indian scientist sage and philosopher was walking with food in his hand as he ate the food after chewing for a while it occcured to him that he could not divide the food into further part

thus the idea of a matter which cannot be divided further came into existence. he called that indivisible matter "anu" a sanskrit word for atoms. Even though sage Kanada was believed to be the first one to come up with this idea,

but the credit for making this concept popular and proposing the first Atomic theory goes to a greek philosopher who explained tht everything around us is made up of tiny particles surrounded by empty space,

he even said that they vary in size and shape depending on the substances they compose. He name this particle atomos, agreek word for indivisible and as time progressed this theory went uinto many chnage and challenges and finally we know atoms.
