Consider the scene ... If I were to ask you what is water made of what would you say? Molecules of hydrogen and oxygen. What are the hydrogen and oxygen made of? Protons neutrons and electrons. What are the protons neutrons and electrons made of? ….This is what particle physics aims to find out. PDST Resources for Leaving Certificate Physics 2 Particle Physics What is Particle Physics To do this, you need to all about? Let’s be more think……. BIG specific! It is a study of the most basic building blocks of matter and the forces that act upon them. We want to understand how these basic building blocks interact to make the universe look and behave the way it does. PDST Resources for Leaving Certificate Physics 3 Requirements? What do we need to study particle physics? We need the fastest computers The coldest temperatures and the strongest magnets on the planet! PDST Resources for Leaving Certificate Physics 4 How do we do particle physics? We take a particle we can easily reproduce, such as a proton, and we accelerate it around and around in a circle faster and faster until it almost reaches the speed of light... and then we smash them together and see what happens! PDST Resources for Leaving Certificate Physics 5 What do we know so far? We have a body of knowledge called the standard model it says that all matter is made up of 12 fundamental particles (6 quarks and 6 leptons) acted on by three of the four forces of nature –the strong force, –the weak force and –the electromagnetic force.
