Los Alamos National Laboratory’s Bradbury Science Museum will unveil two exhibits next week and hosts a talk about Manhattan Project physicist Richard Feynman on Sept.  29.
All the events are open to the public and coincide with Los Alamos County’s “See You In September” celebration of Cultural Heritage Month.
The museum opens its “Fireset” exhibit with a reception from 3 to 4 p.m., Tuesday followed by a discussion and question-and-answer session with Laboratory retiree Glenn McDuff.
“The Fireset: How Fat Man was Triggered,” features the only known remaining original fireset made to work with the Fat Man nuclear device. The exhibit describes how this artifact worked and why it was a crucial part of the perfectly synchronized ignition of the high explosives used to detonate Fat Man, while also protecting against misfires.
Two days later, “A NewLook at Trinitite” opens with a welcome and reception from 3 to 4 p.m. and a discussion and question-and-answer session with Laboratory scientist Robb Hermes.
The trinitite exhibit uses this famous green glass produced by the first atomic device test at Trinity Site to tell a story about the scientific method.
