Three historic sites that were the center of the Manhattan Project are on their way to becoming a national park. The Manhattan Project was the code name for the work that created the atomic bomb. The park will be named the Manhattan Project National Historical Park. Park sites will be in New Mexico, Tennessee, and Washington. One physicist at Lawrence Livermore National Laboratory believes the Manhattan Project park is important. He says people should understand the fear that drove this scientific work. It was the fear during World War II (1939–45) that the Nazis would make an atom bomb first because many great physicists lived in Germany.
