Modern Atomic Discoveries

The journey to understanding atoms gained momentum in the 19th century with Dalton's groundbreaking proposal that elements consist of unique atoms reacting in specific ratios. Observations of Brownian motion by a botanist provided further evidence, as Einstein later explained this erratic movement as the result of water molecules colliding with dust grains. Together, these insights reinforced the notion that matter is discrete rather than continuous, cementing the atomic theory's place in science.
