Philosophy of Atom by Acharya Kanad

Acharya Kanad and Atomic Theory

• Acharya Kanad is recognized as the father of atomic theory, having formulated his ideas around 2500 BCE.
• He introduced the concept of 'atom' prior to John Dalton's atomic theory.
• The term 'atom' is derived from the Sanskrit word found in his work 'Vaisesika Sutra.'

Key Concepts of Kanad's Atom

• Atoms are described as indivisible particles that make up all matter.
• The term 'mahat' (great) refers to the collective size of atoms when unified.
• In the absence of unity among atoms, they remain as separate entities, known simply as 'atoms.'

Visibility of Atoms

• Atoms are not observable in ordinary life, while larger objects are visible.
• Kanad theorized about the visibility and invisibility of atoms, predating discussions about carbon dioxide (CO2) visibility.
• This distinction highlights early philosophical considerations of matter and perception.
