Professor Paul Harrison came in to talk to us about particle physics. He began by telling us about the standard model of elementary particles and about quarks and gluons- including the composition of protons and neutrons, and how all quarks are point like (can't be measured) and bound. He then moved on to tell us about the 'Guiding Principles of Particle Physics':
He then moved on to talk about his work at CERN, as well as telling us briefly about the discovery of the Higgs boson particle, and what is made on particle colliders. Lastly, he talked about the questions still facing particle physicists today: Is the Higgs boson as expected? Why is the Higgs bosons mass stable? Is the dark matter of the universe really a new undiscovered particle? How to unify strong force with weak and electromagnetic? Why do elememtary particles take the masses they do?
