This book reads like an official museum guide that introduces the Trinity test and the early history of nuclear weapons through the lens of the National Atomic Museum’s collections. It covers the Manhattan Project’s scientific and military context, the July 16, 1945 Trinity detonation in New Mexico, key people and technologies involved, and how the test site and its artifacts are preserved and interpreted today. Expect a concise, visitor-oriented format with historical summaries, photographs/illustrations of exhibits and objects, and practical background on what the museum and Trinity Site commemorate.
