Ernest Rutherford

Ernest Rutherford (30 August 1871 – 19 October 1937) was a New Zealand-born British physicist who came to be known as the father of nuclear physics. He is best known for his pioneering work in the study of radioactivity, and his development of the planetary model of the atom.

Early Life and Education[edit | edit source]

Ernest Rutherford was born in Brightwater, New Zealand, on 30 August 1871. He was the fourth of twelve children. His father, James Rutherford, was a farmer, and his mother, Martha Thompson, was a schoolteacher. Rutherford attended Nelson College and won a scholarship to study at Canterbury College, University of New Zealand, where he participated in the study of physics and mathematics.

Career[edit | edit source]

In 1895, Rutherford was awarded an 1851 Research Fellowship from the Royal Commission for the Exhibition of 1851, to travel and study at the Cavendish Laboratory, University of Cambridge. There, he conducted research under the guidance of J.J. Thomson, and his work led to the discovery of the concept of radioactive half-life, proving that radioactivity involved the transmutation of one chemical element to another.

In 1911, Rutherford postulated the existence of a compact atomic nucleus, with positively charged particles ('protons') surrounded by 'orbiting' electrons. This became known as the Rutherford model of the atom, or the planetary model.

Legacy[edit | edit source]

Rutherford's work has had a profound impact on the field of physics, and he is widely regarded as one of the greatest experimentalists in the history of the subject. His work on the structure of the atom has been fundamental to our understanding of the physical world.
