The Cambridge HEP pages for schools, educators and the general public

  • In a 27km tunnel, 100m underground, protons zip around, crossing the Franco-Swiss border 22000 times every second.
  • Discover how we can see the paths of particles in our detectors. Our spark chamber shows the cosmic ray particles that are all around you.
  • Huge teams of scientists are needed for our experiments. Here are some of the scientists behind (and in front of) one of the particle detectors that we work on.
  • Nature tries its luck at combining up, down and strange quarks into protons, pions and kaons to build the Universe from its fundamental constituents.
  • Particle physics theory calculations make use of Feynman diagrams. Their appearance has inspired theoreticians to name them after animals, plants and birds like this penguin diagram.
  • We are trying to find the answers to some fundamental questions. What secrets might the Large Hadron Collider reveal?
  • A part of our exhibit that we took to the 2011 Royal Society Summer Science Exhibition with our Birmingham Particle Physics partners.
  • Our Cosmic Ray Observatory for Cambridgeshire Schools project is putting particle detectors into schools in our region.
  • Explaining cosmic rays to visitors using our spark chamber.

Scatter! is the University of Cambridge High Energy Physics Group web site for schools, educators and the general public. Here we have gathered together various educational resources related to our work that have originated within the group or with which we have been closely associated. We hope that you will find them useful, interesting and fun.

Please use the links on the left of this page to navigate around this site. You will find various outreach projects in which members of the HEP Group are currently involved and events that have taken place in the last few years. You will also find information about the annual Masterclass and Physics at Work events for schools.

We have also included links to other sites with related material that may be of interest.

High Energy Physics (also often called Particle Physics) is the physics of the most fundamental constituents of matter and the interactions between them. The theories that we use to describe these interactions combine field theory, quantum mechanics and relativity. The predictions of these theories have been tested to very high precision in a variety of experiments, most notably using accelerators that collide particles at very high energies. Examples are the Large Electron Positron collider (LEP) and now at the Large Hadron Collider (LHC) at CERN where most of the experimental activity of the Cambridge High Energy Physics group is focussed.


Future events are highlighted green.
