Why was the Manhattan Project successful?
The goal of the Manhattan Project was effectively summed up by scientist Robert Serber when he deduced, “Since the one factor that determines the damage is the energy release, our aim is simply to get as much energy from the explosion as we can.”[1] Thus, due to the nature of the program’s objective, the Manhattan Project is one of scientific engineering’s foremost successes.
When does the Manhattan Project start?
With this basic knowledge of atomic chemistry and the motivation of a world crisis, the Manhattan project began in 1942. Two prominent challenges delayed the successful unleashing of nuclear energy: processing of sufficient fissionable material, and the actual design of a nuclear bomb that would maintain and maximize a fissile chain reaction.
Did Robert Oppenheimer regret the atomic bomb?
Oppenheimer alluded numerous times to feelings that strongly imply he regretted inventing the bomb, or at least regretted the bomb being used. He certainly wasn’t a fan of how the bomb was capable of ending the world. As for how most Americans feel, that’s a more complicated question.
Why was the Manhattan Project named Manhattan Project?
Why was the Manhattan Project named Manhattan Project? The Manhattan Project was the code name for the U.S. effort during World War II to produce the atomic bomb. It was named for the Manhattan Engineer District of the U.S. Army Corps of Engineers, because much of the early research was done in New York City.

The Manhattan Project was under enormous time pressure, partly because intelligence suggested that Nazi Germany was further ahead with nuclear weapons research than was actually the case. Groves chose to de-emphasise the kind of prototyping that was common in military projects of the day in order to save time. In a move that foreshadowed Agile development practices, he was also willing to move forwards with only partially completed plans, using an energetic work ethos, determination, disciplined modularisation and careful recruitment to compensate.

Early Life
A Problem with His Conscience
- The massive destruction the bombs inflicted troubled Oppenheimer. He had been so caught up in the challenge of creating something new and the competition between the U.S. and Germany that he—and many of the other scientists working on the project—had not considered the human toll that would be caused by these bombs. After the end of World War II, Oppenheimer began to voic…
Award

Death
- Oppenheimer spent his remaining years researching physics and examining the moral dilemmas related to scientists. Oppenheimer died in 1967 at age 62 from throat cancer.
Legacy
- The invention of the atomic bomb had a profound impact on the outcome of World War II and on the ensuing Cold War and arms race. Oppenheimer's personal ethical dilemma has become the focus of myriad books and several plays, including In the Matter of J. Robert Oppenheimer.
