The revision by Whizz40 on 20:59, 2 September 2023 is not referenced, POV, and incorrect. The original sentence read "It was led by the United States with support from the United Kingdom and Canada." which is more correct than their revision. 70.51.132.220 (talk) 04:53, 11 March 2024 (UTC)


 * Changed to "It was led by the United States in collaboration with the United Kingdom and Canada." Hawkeye7   (discuss)  08:06, 11 March 2024 (UTC)

Please add this section as is in regards to Teller's group contribution.

A special group was established under Teller in March 1944 to investigate the mathematics of an implosion-type nuclear weapon. Because of his interest in the Super, Teller did not work as hard on the implosion calculations as Bethe wanted. These too were originally low-priority tasks, but the discovery of spontaneous fission in plutonium by Emilio Segrè's group gave the implosion bomb increased importance. In June 1944, at Bethe's request, Oppenheimer moved Teller out of T Division, and placed him in charge of a special group responsible for the Super, reporting directly to Oppenheimer. He was replaced by Rudolf Peierls from the British Mission, who in turn brought in Klaus Fuchs, who was later revealed to be a Soviet spy. Teller's Super group became part of Fermi's F Division when he joined the Los Alamos Laboratory in September 1944. It included Stanislaw Ulam, Jane Roberg, Geoffrey Chew, Harold and Mary Argo, and Maria Goeppert-Mayer.[1]

African-American scientists and technicians on the Manhattan Project
I just read a great new page, "African-American scientists and technicians on the Manhattan Project," that should be linked to on this main page. Can someone add that link somewhere here? The page is protected, or I would do it myself. Thanks! ProfJsto (talk) 15:05, 12 April 2024 (UTC)


 * ✅ Added a sentence. It is also now in the template, so is present in all the Manhattan Project articles. One problem: the article says As a condition of funding the project, southern legislators required that it be segregated but neither of the cited sources support this sentence.

 * thanks a lot! i didn't make this page, but I can check in on the sources and see what I find. ProfJsto (talk) 21:04, 12 April 2024 (UTC)
 * Okay. I will delete the sentence for now. It can be reinstated if a source can be found. Hawkeye7   (discuss)  22:42, 12 April 2024 (UTC)

Within the article for the Manhattan project, the part about Uranium, more specifically about Gaseous Diffusion seems to have a grammatical mistake, I have put in bold what I think should be added for the sentence to make more sense grammatically speaking.

The process faced formidable technical difficulties. The highly corrosive gas uranium hexafluoride had to be used, as no substitute could be found, and the motors and pumps had to be vacuum tight and enclosed in inert gas. Think and Game (talk) 13:47, 2 May 2024 (UTC)

Clarification
Reading through the article I was confused by: “Briggs proposed spending $167,000 on research into uranium, particularly the uranium-235 isotope, and plutonium, which was discovered in 1940 at the University of California.”

and then later:

“The properties of pure uranium-235 were relatively unknown, as were those of plutonium, which had only been discovered in February 1941 by Glenn Seaborg and his team.”

In researching the source it appears clear that two seperate discoveries were made, the first being the actual substance, and the second being the subtance's properties. The first quote should be reconciled to the second and clarified by striking those and adding “the properties.” TheRealStang (talk) 20:27, 1 July 2024 (UTC)


 * An error. They had evidence that Neptunium decayed to Plutonium, but Plutonium was not isolated until February 1941. I have corrected the text. Hawkeye7   (discuss)  21:52, 1 July 2024 (UTC)

Add Matthew Pascale Von Kolpakow from Эугвуэга Тришу фон Колпаков as page 58, line 9 says, "Мэтью Паскаль фон Колпаков работал над Манхэттенским проектом." Which translates to Russian to mean "This man. He. This man: Matthew Pascale Von Kolpakow: this. Worked on the Manhattan Project."

Could you please add this man to the Manhattan Project page? He worked between 1943 and 1944 before returning to Poland and prompting emigration of his son to Australia. And their child!

 * Aside from the fact that most Manhattan Project personnel are not notable-enough to be listed on this page (thousands of scientists and technicians worked on the Manhattan Project, and hundreds of thousands of other workers), I do not find any citations for this name at all, much less anything that confirms they work on the Manhattan Project. The source listed is unknown to me and gets zero Google hits, so even its most basic nature, or a basic citation, is impossible to discern. The name "Matthew Pascale Von Kolpakow" gets zero Google hits. The name is totally unknown to me and no searching for "Kolpakow" or "Kolpakov" or "Колпаков" among my many books and files turns up any hits of relevance. I don't know what's going on here, but this does not seem legit. If you have some clarification of the above, it might be considered, but even if the figure in question was assumed to exist and to have worked on the project (itself not established), they necessarily seem quite obscure and not warranting mention. --NuclearSecrets (talk) 17:24, 9 July 2024 (UTC)

Not done for now: please establish a consensus for this alteration before using the template. PianoDan (talk) 17:26, 9 July 2024 (UTC)
