The transition from the 19th-century billiard ball model to the modern cloud model is a central theme in the history of atom and its scientific evolution. Each new discovery was built upon the failures and successes of the previous generation of researchers. Nowadays, atomic theory is the basis for electronics, medicine, and energy production. Understanding these milestones allows for a deeper appreciation of the technology that defines the modern world. か
