This meeting initiated an official shift from the research to the development phase of the project.
What breakthrough occurred in 1942 how did it impact the Manhattan Project?
A breakthrough occurred in December 1942 when Fermi led a group of physicists to produce the first controlled nuclear chain reaction under the grandstands of Stagg Field at the University of Chicago. Enrico Fermi, a physicist who left fascist Italy for America, encouraged the U.S. to begin atomic research.
Why was the Manhattan Project kept a secret?
A key component of keeping the Manhattan Project secret was making sure Project sites were secret and secure. One obvious reason the Manhattan Engineers District selected Los Alamos, NM, Oak Ridge, TN, and Hanford, WA as project sites was their geographic isolation.
