Welcome to the new GigaPhysics site. If you have been here before, you'll notice some changes. For one, this site now concentrates exclusively on the part of the site people used the most—the virtual labs. The interfaces to the labs have been updated, in part to make them more friendly to tablet-sized screens. The lab guides have been rewritten to reflect these changes, though (as of May 30, 2026), they are in a sort of first draft state and may get some refinements later on.
