After taking his B.A. degree in mathematics, the opportunity of doing experimental research drew him to the Cavendish Laboratory. In 1883, he received his Masters of Arts degree (with Adams Prize).
Thomson began studying cathode rays, and his research led to the discovery of the electron, and he pursued further innovations in atomic structure exploration. In 1906 he received the Nobel Prize for Physics for his researches into the electrical conductivity of gases. Besides this, he was honored with various prestigious awards such as, in 1908 he was knighted; in 1909 he was made the president of the British Association for the Advancement of Science, and in 1912 he received the Order of Merit.
