Ernest Rutherford

Ernest Rutherford was a pioneering physicist known for his groundbreaking work in understanding atomic structure and radioactivity. In 1909, he conducted the famous gold foil experiment, which revealed that atoms have a small, dense nucleus at their center, leading to the discovery of the proton. Rutherford's work laid the foundation for nuclear physics and chemistry, explaining how atoms behave and interact. He also played a key role in identifying different types of radioactivity, making significant contributions to both theoretical and experimental science. His insights profoundly influenced the development of modern atomic theory.
