Pictures: the father of nuclear physics, Sir Ernest Rutherford

The British physicist of New Zealand origin, known as the “father” of nuclear physics, also the Nobel Prize winner in chemistry in 1908, Sir Ernest Rutherford, was born on August 30, 1871.

We decided to recall the biography of the famous scientist and illustrate its main milestones in our photo selection.

Born on August 30, 1871 in the city of Spring - Brouv (New Zealand) in a family of Scottish immigrants. My father worked as a mechanic and farmer-flax grower, my mother worked as a teacher. Ernest was the fourth of Rutherford’s 12 children and the most talented.

Already at the end of elementary school, as the first student, he received an award of £ 50 to continue his education. Due to this, Rutherford entered college in Nelson (New Zealand).

After graduating from college, the young man passed the exams at the University of Canterbury and here he was seriously engaged in physics and chemistry.

“If a scientist cannot explain what he is doing, a cleaner cleaning the floor in his laboratory, then he himself does not understand what he is doing”

J.J.Tomson, like many outstanding professors of physics at the end of the 19th century, gathered a group of bright young "students-researchers" around him. Directly among them is his protege Ernest Rutherford.

He participated in the creation of a scientific student society and made a report in 1891 on the theme “The Evolution of Elements”, where the idea was first expressed that atoms are complex systems built from the same components.

At a time when J. Dalton’s idea of ​​the indivisibility of the atom reigned in physics, this thought seemed absurd, and young Rutherford even had to apologize to his colleagues for “obvious nonsense.”

True, after 12 years, Rutherford proved his point. After graduating from university, Ernest became a high school teacher, but he clearly did not like this occupation. Rutherford - the best graduate of the year - was awarded a scholarship, and he went to Cambridge - the science center of England - to continue his studies.

In the Cavendish Laboratory, Rutherford created a transmitter for radio communications within a radius of 3 km, but gave priority to his invention to the Italian engineer G. Marconi, while he himself began to study the ionization of gases and air. The scientist noticed that uranium radiation has two components - alpha and beta rays. It was a revelation.

In Montreal, when studying the activity of thorium, Rutherford discovered a new gas - radon. In 1902, in his work The Cause and Nature of Radioactivity, the scientist first suggested that the cause of radioactivity is the spontaneous transition of some elements into others. He found that alpha particles are positively charged, their mass is greater than the mass of a hydrogen atom, and the charge is approximately equal to the charge of two electrons, and it resembles helium atoms.

In 1903, Rutherford became a member of the Royal Society of London, and from 1925 to 1930 he served as its president.

In 1904, the fundamental work of the scientist “Radioactive substances and their radiation,” which became an encyclopedia for nuclear physicists, was published. In 1908, Rutherford became a Nobel laureate for his research on radioactive elements. Head of the Physics Laboratory at the University of Manchester, Rutherford created a school of nuclear physicists, his students.

Together with them, he was engaged in the study of the atom in 1911. He finally came to the planetary model of the atom, as he wrote in an article published in the May issue of The Philosophical Journal. The model was not accepted immediately, it was established only after it was finalized by the students of Rutherford, in particular N. Bohr.

The scientist died on October 19, 1937 in Cambridge. Like many great people of England, Ernest Rutherford rests in the Cathedral of St. Paul, in the "Corner of Science", next to Newton, Faraday, Darren, Herschel.
