How do John Daltons discovery effect or change our world?

John Dalton's discovery of atomic theory fundamentally changed our understanding of matter and laid the groundwork for modern chemistry. By proposing that all matter is composed of indivisible atoms and that different elements have distinct types of atoms, Dalton provided a framework for explaining chemical reactions and the formation of compounds. This shift in perspective not only advanced scientific inquiry but also paved the way for innovations in various fields, including medicine, materials science, and energy, ultimately impacting technology and industry in profound ways. Dalton's work continues to influence scientific research and education today.
