J.J. Thomson discovered the electron in 1897 and led the Cavendish Laboratory into a world-class research institution. His work opened the field of subatomic physics to experimental investigation and helped unravel the inner workings of the atom. He deve

J.J. Thomson's cathode ray tube experiment discovered the subatomic particle the electron. Prior to the experiment, it was not known that atoms were composed of further particles. Cathode rays were determined to be composed of negatively charged particles that were smaller than the smallest atom....

J.J. Thomson was a Nobel Prize-winning physicist whose research led to the discovery of electrons.
aIn the model proposed by J.J. Thomson [3] in 1904, the atom was considered like a fluid with continuous spherical distribution of positive charges where electrons with negative charges were embedded, in a number sufficient to 在J.J.提议的模型。 Thomson (3) 1904年,原子被考虑了象流体以正...
One of the things I love most about Laracon is being exposed to more advanced topics in software engineering that I might not have otherwise discovered. For example:Database Indexing –The art of indexing a database is kind of obscure, but the pursuit of fast queries and ‘groking’ data...
Thomson's master's work,Treatise on the motion of vortex rings, provides a mathematical description of William Thomson's vortex theory of atoms. He was awarded the Adams Prize in 1884. Thomson discovered the natural radioactivity of potassium in 1905. In 1906, Thomson demonstrated a hydrogen ato...
