- The idea of atoms as the smallest units of matter was proposed by John Dalton in 1803, based on his experiments with different substances1. However, the direct evidence of atoms was not observed until 1827, when Robert Brown noticed that pollen grains in water moved randomly due to collisions with water molecules2. This phenomenon was explained by Einstein’s theory in 1905, and confirmed by observations and calculations in 19083.

He concluded that all matter was made of tiny particles called atoms. He suggested that an atom was a tiny solid ball. He published his ideas in 1803.www.bbc.co.uk/bitesize/guides/zp3dh39/revision/1The first truly direct evidence of atoms is credited to Robert Brown, a Scottish botanist. In 1827, he noticed that tiny pollen grains suspended in still water moved about in complex paths. This can be observed with a microscope for any small particles in a fluid.openstax.org/books/college-physics/pages/30-1-dis…Einstein’s theory was that that the particles from the pollen grains were being moved around because they were constantly crashing into millions of tinier molecules of water – molecules that were made of atoms. By 1908, observations backed with calculations had confirmed that atoms were real.ielts-up.com/reading/sentence-completion-lesson.h… - People also ask
