阿尔伯特·爱因斯坦是一位德国物理学家，他提出了相对论，他把原子弹的想法和其他著名的物理学家一起思考了。在第二次世界大战开始时，德国物理学家Fritz Strassmann和Otto Hahn想用核裂变来分裂铀原子。后来在战争中，一群美国科学家开始了曼哈顿计划，正式名称为曼哈顿工程师区。莱斯利·格罗夫斯将军领导着这个项目，由物理学家j·罗伯特·奥本海默管理的科学研究部门，他被称为“原子弹之父”。实验制造了原子弹，由美国、加拿大和英国资助。曼哈顿计划有四个实验室，他们在那里制造炸弹。这些地点分别是:Richland,Washington,Oak Ridge,Tennessee,Los Alamos,New Mexico,and Chalk River,Ontario,Canada。令人震惊的是，美国第32任总统富兰克林·德拉诺·罗斯福(Franklin Delano Roosevelt)在第二次世界大战期间，将炸弹的生产秘密地保留在国会和公众面前。事实上，当杜鲁门宣誓就职时，他就知道了这个计划。科学家们制造了三枚炸弹，小玩意，小男孩和胖子。这个小玩意和那个胖子是一种类似的炸弹;然而，科学家们并不确定这种类型的炸弹是否会起作用。温哥华代写assignment：阿尔伯特·爱因斯坦.这项名为“三位一体”的测试于1945年7月16日凌晨5:30在新墨西哥州引爆。每一位科学家都为原子弹的成功而兴奋不已，离测试地点一百英里远的市民也能感受到爆炸的亮光。令人惊讶的是，一个失明的女孩在120英里外看到了闪电。三位一体是炸弹可用的绿灯。三周后将在日本使用。
Albert Einstein, a German physicist who came up with the theory of relativity, thought of the idea of the atomic bomb with other noted physicists. In the beginning of World War II, Fritz Strassmann and Otto Hahn, German physicists, thought of splitting uranium atoms by nuclear fission. Later in the war, a group of American scientists began The Manhattan Project, formally known as The Manhattan Engineer District. General Leslie Groves led the project and the scientific research department managed by physicist J. Robert Oppenheimer, known as "The Father of the Atomic Bomb." The experiment created atomic bombs, which were funded by the Americans, Canadians, and the British. The Manhattan Project had four laboratories where they created bombs. The locations were Richland, Washington, Oak Ridge, Tennessee, Los Alamos, New Mexico, and Chalk River, Ontario, Canada. Shockingly, Franklin Delano Roosevelt, the thirty-second president of the United States, kept the production of the bombs a secret from Congress and the public during World War II. In fact, Truman figured out about this project when he was sworn into his presidency. The scientists created three bombs, the Gadget, Little Boy and Fat Man. The Gadget was a similar type of bomb as the Fat Man; however, the scientists were unsure if either of this type of bomb would work. The test, called Trinity, conducted to detonate the Gadget in New Mexico on July 16, 1945, at 5:30 in the morning. Every scientist was thrilled by the success of the bomb, and citizens one hundred miles away from the testing location could feel and see the bright light from the explosion. Astonishingly, a blind girl saw the flash up 120 miles away (Bellis). The Trinity was the green light that the bombs were usable. They would be used three weeks later in Japan.
