who developed the theory of atomism and believed that all things consist of particles called atoms
Atomism References to the concept of atomism and its atoms are found in ancient India and ancient Greece. In the West, atomism emerged in the 5th century BCE with Leucippus and Democritus.[6] In India the Jain,[7][8] Ajivika and Carvaka schools of atomism may date back to the 4th century BCE.[9] The Nyaya and Vaisheshika schools later developed theories on how atoms combined into more complex objects.[10]
