The U.S. Army took over atomic research in the early 1940s primarily due to the urgency of World War II and the potential military applications of nuclear technology. Following concerns that Nazi Germany was developing atomic weapons, the U.S. government sought to accelerate its own research efforts. This led to the establishment of the Manhattan Project, which centralized atomic research under the Army Corps of Engineers to ensure a coordinated and rapid development of nuclear weapons. The project's focus was on harnessing nuclear fission for military use, ultimately culminating in the atomic bomb.
One event that caused great fear in the United States in 1949 was the communist takeover of China. The other event was the Soviet Union detonating an atomic bomb.

Willy Higginbotham, who invented the first video arcade game, worked on advanced radar displays for B28 bombers and went on to work for the Manhattan Project where he designed the timing mechanism for the first atomic bomb in the early 1940's.

An atomic pile is a type of nuclear reactor that uses natural uranium as fuel to sustain a controlled nuclear reaction. It is an early form of nuclear reactor developed in the mid-20th century for research and experimental purposes.
Computers were invented in the early to mid 1940s.

Anne Frank longed for freedom, peace, safety, and a world without persecution during the early 1940s while hiding from the Nazis in Amsterdam.
The development of atomic energy was introduced in the early 20th century, with significant advancements occurring in the 1940s during World War II. This led to the first successful nuclear reactions and the subsequent harnessing of atomic power for both military and civilian purposes.
On very early versions of the Periodic Table the elements were organized by atomic mass, because it was measurable and the concept of atomic number was unknown. After Rutherford and Bohr developed their model of the structure of the atom, the Periodic Table was reorganized by atomic number (which caused a few elements to swap positions).
