Because it made the single most destructive weapon ever used in any war, before or since. The use of this weapon gave the Japanese government an excuse they could use for surrendering without taking on too much disgrace for doing so, thus quickly ending the war.
The Manhattan Project IS the codename. So no, there is not.
yes it would have been accomplished if we were not at war
The Manhattan Project not only built the bombs that ended the war and saved millions of lives it helped scientists learn to harvest plutonium, uranium and to harness its power so they could eventually make nuclear powered ships and reactors for power.
The Manhattan Project resulted in the development of the atomic bombs that were dropped on Japan in world war two. The most immediate impact was on Japan since hundreds of thousands of people were killed. Ultimately the entire human race was impacted by the nuclear arms race.
The top secret program to build an atomic bomb was called the Manhattan Project. It was so secret the top Generals and Admirals did not know about it. The people who worked on the project often did not know what they were working on. All the workers lived in places that were developed from the ground up and they could not talk about what they were doing. Even Vice President Truman did not know about it until after President Roosevelt died.
The scientists did not "give up" on the Manhattan Project. They accomplished their goals of developing three atom bombs. The Project ended at the end of the war. The workers went home and much of the "little towns" were taken down. There was no need for the project to continue after the war. It cost 2 billion dollars back then to create the three bombs so the government would not fund it any further when there was no need for further work.
possibility that Germans were building atomic bomb
While the B29 was expensive it cannot even compare to the real most expensive project of World War 2. The Manhattan Project was the most costly project to develop the atom bombs used in World Wa2. This project cost well over 2 Billion Dollars in the 1940s. That would be like a 20 Billion or so dollars today. So the atom bombs each cost slightly under a billion dollars a piece.
Most of them were patriots and some other was soviet spies.
There weren't 6 African scientists on the Manhattan project. They were all European or American. It was rare indeed for a black man to be allowed an education in those days. It is doubtful that any got so far as to achieve a PhD in physics or chemistry. It is certain that none were part of project Manhattan. ------------- The above comment is not true - African-American scientist J. Ernest Wilkins got a PhD in 1942 and from 1944 worked on the Manhattan Project in the University of Chicago's Met Lab.
no, but they did help the US work on the Manhattan Project, so they had the classified data on how to build them.
nobody asked to work on the project, if told its purpose, refused the opportunity to work on a weapon so important to the war. although the majority of manhattan project workers (they were not cleared and had no need to know in order to perform their jobs) had no idea that what they were working on was an atomic bomb. however any soldiers on the project that breached security were instantly removed from the project and reassigned to remote bases in alaska!
