Learn more about the host city, Los Alamos.
Los Alamos is a small town in northern New Mexico, about an hour northwest of Santa Fe. Its claim to fame is the Los Alamos National Laboratory (LANL), where Oppenheimer and other physicists created the world's first atomic bomb during World War II, concluding the Golden Age of Modern Physics and heralding the Atomic Age. Many of Los Alamos's 12,000 residents work at the laboratory. White Rock, with about 6,000, is a part of Los Alamos, but is separated from the main town by LANL. Nearly all of LANL is closed to the public, but the town has a couple of museums which are good places to learn about the history of the town.
