Discovered cathode rays
On 22 December 1884, Thomson was appointed Cavendish Professor of Physics at the University of Cambridge. The appointment caused considerable surprise, given that candidates such as Osborne Reynolds or Richard Glazebrook were older and more experienced in laboratory work. Thomson was known for his work as a mathematician, where he was recognized as an exceptional tale… WebApr 10, 2024 · Wilhelm Conrad Roentgen discovered that the Crookes tubes he was using to research cathode rays emitted a new kind of invisible ray that could penetrate the black paper. The recently observed x-rays entered the body's soft tissue as well, and the medical world recognised their use for imaging almost immediately.
