31 Interesting Facts about J. J. Thomson

Joseph John Thomson, also known as J.J. Thomson, was a British physicist who was born on December 18, 1856, in Cheetham Hill, a suburb of Manchester, England. He is best known for his discovery of the electron, which revolutionized our understanding of the nature of matter.

Thomson was educated at Owens College in Manchester, where he excelled in mathematics and physics. After completing his studies, he worked as a professor of physics at the University of Cambridge, where he spent most of his career.

In 1897, Thomson made his most significant discovery when he observed that cathode rays, a beam of negatively charged particles, could be deflected by a magnetic field. This led him to propose that these particles, which he called “corpuscles,” were actually subatomic particles, later known as electrons. This discovery earned him the Nobel Prize in Physics in 1906.

Thomson’s work on the electron also led to his development of the “plum pudding” model of the atom, which proposed that the atom was a sphere of positive charge with negatively charged electrons scattered throughout. This model was later revised by Ernest Rutherford, who proposed the concept of a nucleus, but Thomson’s work paved the way for the modern understanding of atomic structure.
