Our favorite was the exhibit describing circumstances in which the Manhattan Project was born, and the story behind its set up and growth. For example, I found it incredibly interesting and thrilling to read an original of Einstein's Letter to Roosevelt, in which he warned the president of a new kind of bomb that Germans might have been working on. As a scientist, I was touched to see that we actually sometimes have something important to say and that our voices are being heard.
