Thomson, was a British physicist who first theorized and offered experimental evidence that the atom is a divisible entity rather than the basic unit of matter, as was widely believed at the time. A series of experiments with cathode rays he carried out near the end of the 19th century led to his ...
WebThe Discovery of the Electron (J. J. Thomson) In 1897, J. J. Thomson found that the cathode rays can be deflected by an electric field, as shown below. By balancing the effect of a magnetic field on a cathode-ray beam with an electric field, Thomson was able to show that cathode "rays"are actually composed of particles. This experiment also ... In "A Defense of Abortion", Thomson grants for the sake of argument that the fetus has a right to life, but defends the permissibility of abortion by appealing to a thought experiment: You wake up in the morning and find yourself back to back in bed with an unconscious violinist.
