Cavendish Professor of Physics the university regulations which allowed students who had not studied at Cambridge to receive a B.A. by submitting a thesis which was judged "of distinction as a record of original research." Among the students attracted by this change was future Cavendish Professor Ernest Rutherford. Whilst Thomson was Cavendish Professor, he discovered the electron and the existence of isotopes, and also fostered an atmosphere of friendliness and mutual helpfulness. Rutherford returned to Cambridge in 1918, and spent the last 19 years of his life there. This was around the time of the change from classical to modern physics, and Rutherford was
Laboratory of Instrumentation and Experimental Particles Physics with the University of Coimbra, the Lisbon University, the Technical University of Lisbon, the New University of Lisbon, the University of the Minho and the University of Beira Interior. LIP is involved in scientific research on issues related to high energy physics and instrumentation, working heavily with CERN, of which Portugal is a full member. LIP has also been involved in space science projects with NASA, the Pierre Auger Observatory, the SNOLAB, and the European Space Agency, and conducts research in Monte Carlo methods for medical physics. The laboratory is also involved in the Ibercivis distributed computing project. Laboratory of
