Experimentalists in high-energy physics are probing at the smallest scales of length to learn about the fundamental nature of elementary particles and the interactions between them. In addition they are performing precision tests of the standard model and searching for new physics beyond it. The goal of experimental astrophysics is to determine the nature of the universe through observations of radiation reaching the Earth from space.

Precision measurements at low energies provide an alternate path to the frontier in particle physics, and provide complementary information to that obtained at the highest-energy colliders. Both kinds of information will be necessary if we are to understand the data obtained at the Large Hadron Collider. See the medium-energy page for more details.
