Who is the forerunner of modern atomism

Answer 1

The forerunner of modern atomism is often attributed to the ancient Greek philosopher Democritus (c. 460 – c. 370 BCE). Democritus developed the idea that all matter is composed of indivisible and indestructible particles called "atoms." He proposed that atoms are constantly moving and combine in different arrangements to form different substances. Democritus' theories laid the foundation for the development of modern atomic theory.
