the top quark and the Higgs safely in hand, physicists will still face a host of issues. The question of the size of the universe, and why it is not curled up into the size of a football, is only one of them.

"I do not know what I may seem to others," wrote Isaac Newton. "But, as to myself, I seem to have been only as a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me." In this spirit, rather than with the hope of final and ultimate insight, physicists may welcome new accelerators such as the LHC, as they usher in the agenda of the next century. Our researchers may divert themselves with the pretty shells of the top quark and even the Higgs, but Newton's ocean still conceals many of the truly deep issues: The origin of mass; the origin of the universe; the character of a truly ultimate theory of nature, if indeed a theory exists. For all our hope and all our work to date, we still must stand with Paul: "We know in part, and we prophesy in part. … Now we see through a glass, darkly."
