Wikipedia should be interesting edit

Who was the jerk who deleted the medal theft paragraph? It is news, all over the papers in USA. Nobel medals are pure gold and also precious for their symbolic value. The fact that he donted his medal for post-mortem public display and the museum was morons to display such a rare and valuable object without true security is notable and revelant. Restoration is thus demanded! 82.131.210.162 10:06, 10 March 2007 (UTC)Reply

Proposed: altering existing photo link to Lawrence images at the Emilio Segrè Visual Archives edit

I'd like to propose changing the photo link from [1] to [2] as this latter link shows all of the Lawrence images at ESVA. In page History, see change made 1/25/2010.

Sure, looks good, makes sense. Binksternet (talk) 18:49, 3 February 2010 (UTC)Reply

MIT work on RADAR edit

How would we go about adding His pioneering work at MIT to help the British develop RADAR that ended with his giving them his best man Luis Alvarez, once the initialproblems had been solved, to miniaturize the components for use in aircraft? Scslate (talk) 09:32, 26 January 2013 (UTC)Reply

I'm happy to review this over the weekend. Jamesx12345 20:01, 20 September 2013 (UTC)Reply

  • "1939 for his invention of the cyclotron atom-smasher" - is "atom smasher" colloquial? I've always thought it is, and if that is the case, it is probably redundant.
  • "and two years later became the youngest full professor at the University of California" - "becoming the youngest full professor there two years later."
  • "Lawrence was intrigued by a diagram of a device to" - this is very abrupt - could it be started, "Whilst at..., Lawrence was intrigued"
  • "high-energy particles and pondered how to make the accelerator more compact. He created a circular accelerating chamber" - "high-energy particles. Contemplating how to make the accelerator more compact..."
  • "the cyclotron" - "the first cyclotron"
  • Radiation Laboratory should be linked
  • A ref in the intro for his support of Teller would be good (obviously pretty contentious.)
    •  Y Easily done, but I wouldn't have thought it was contentious. Hawkeye7 (talk) 20:59, 20 September 2013 (UTC)Reply
I've always thought that the Teller/Oppenheimer caused massive divisions - that's not quite the same, though.
  • "after his first year.[2] Lawrence completed" - "after his first year.[2] He completed"
  • "Instead of using it to travel to Europe, remained at Yale University with Swann as a researcher" - missing "he"
  • Two sentences with "They showed" could probably be run together.
  • "people who were unimpressed" - "who were" can be removed.
  • In 1928, Lawrence... - this paragraph needs references for his membership being sponsored and meeting people there.
  • "Lawrence named his son Robert after J. Robert Oppenheimer, his closest friend at Berkeley"
  • "Lawrence saw that such..." - needs a few more references.
  • "to do the work." - needs a ref (even if it is a self-evident truth.)
  • "Hiring good people and paying them little or nothing would prove to be a sound business model." - likewise
  • "able to accelerate ions to 1 MV." - is that 1 MeV?
  • "more than enough for his PhD thesis." - this could be expanded, even just to say "more than enough to obtain the results he needed for his PhD thesis."
    •  Y No, the construction of a cyclotron was the subject of his thesis. Hawkeye7 (talk) 21:26, 20 September 2013 (UTC)Reply
  • "as soon as there was the first signs of success" - should signs be singular?
  • Added space to $800 11-inch
  • "Lawrence found an 80-ton magnet" - "The magnet for the $800 11-inch cyclotron weighed 2 tons, and the magnet for the 27-inch one weighed 80 tons." - removes the possibility that he stumbled across 80 tons of magnet.
    • No, he stumbled across 80-tons of magnet. It was used by the Navy for something. I'll have to expand this, but haven't got the book on hand here. Please give me a few days. Hawkeye7 (talk) 21:26, 20 September 2013 (UTC)Reply
This link is from the American Institute of Physics, so definitely satisfies RS.
  • "well within the capability of the 11-inch cyclotron." - ref needed
  • Something of a contradiction between the paragraph beginning "Through his increasingly..." and the previous one. Perhaps "this did not translate immediately into scientific discovery" would make more sense?
  • "but they had overlooked another important discovery." - it would be nice to know what!
    •  Y Fusion. I thought is was obvious, but tried to make it clear. Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • "He the first at Berkeley to become a Nobel Laureate, and the first ever to be so honored while at a state-supported university." - a bit more concise
  • "campus of the university with Lawrence receiving" - "campus of the university, with Lawrence receiving" - add a comma
    •  Y Decided to split the long sentence instead., Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • "After the outbreak of World War II in Europe..." - ref for recruiting and security reasons.
    • There is already a reference in the paragraph. Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • Added space to "submarines. Meanwhile"
  • "Oliphant met with Lawrence at Oppenheimer at Berkeley" - I assume that is "Lawrence and Oppenheimer"?
  • "Lawrence had already thought about the problem of uranium enrichment, for only the uranium-235 isotope is fissile." - "Lawrence had already thought about the problem of uranium enrichment, for only the uranium-235 isotope will undergo the fission reaction necessary to create a bomb" - or something like that
    • No, that is not correct. Fissile is what we want. Uranium 238 will fission in a high flux situation, and was used as a tamper. Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • "One way of separating the isotopes was with a mass spectrometer, so Lawrence began converting his old 37-inch cyclotron into a giant mass spectrometer" - "One of the proposed ways of separating the isotopes was with a mass spectrometer, so Lawrence began converting his old 37-inch cyclotron for that purpose."
    • No, that is not correct. It wasn't a proposed way; it was already known to work. But it only produced small quantities, and could not be used on an industrial scale. Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • "laboratory mass spectrometer and cyclotron" - "and the cyclotron"
  • "bolstered by twenty nine British scientists until Oliphant" - confusing meaning.
    •  Y It should be "including Oliphant" Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • "scientifically elegant" - according to whom? I know Feynman hated it.
    •  Y Probably for this reason. Gaseous diffusion was a better solution, but no one knew how to get it to work. Basically, the technology risk in the electromagnetic method was low. Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • Stone & Webster can be linked. (A reference for their building it would also be nice)
    • The paragraph is already referenced. Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • "and had to be fastened more securely." - needs a ref (I can only imagine what would happen to all the computers...)
    • The paragraph is already referenced. Hawkeye7 (talk) 22:30, 20 September 2013 (UTC)Reply
  • "demonstration would be wise" - also needs a ref
    • The paragraph is already referenced. The article is fully referenced. Hawkeye7 (talk) 00:39, 21 September 2013 (UTC)Reply
  • "requirements for big machines and big money" - "costly apparatus and large teams of experimenters" Some references for this paragraph as well would be good.
    • The paragraph is already referenced. The article is fully referenced. Hawkeye7 (talk) 00:39, 21 September 2013 (UTC)Reply
  • "a new linear accelerator and a new billion electron volt synchrotron which became known at the bevatron" - "a new linear accelerator and a billion electron volt synchrotron which later became known at the bevatron"
  • "The major obstacle was the contracts due to expire on July 1, 1948" - confusing again
  • "The 184-inch was completed" - "The 184-inch cyclotron was completed"
  • "pi meson" - "pion" - more common name
    • But anachronistic. It was not yet called that. Hawkeye7 (talk) 00:39, 21 September 2013 (UTC)Reply
  • "Lawrence banned Robert Oppenheimer's brother" - is "banned" the most appropriate word here. It's hard to tell if he was forced to leave or not allowed to take up a position.
    • He wasn't allowed in the building. Hawkeye7 (talk) 00:39, 21 September 2013 (UTC)Reply
  • "which had commenced operation." - ref
    • The paragraph is already referenced. The article is fully referenced. Hawkeye7 (talk) 00:39, 21 September 2013 (UTC)Reply
  • "For his service to his country" - "For service to his country"
  • Is there a link for the proposed treaty?
  • I assume he died of colitis? It would be good just to make that absolutely clear.
    • Sort of. I will expand this.
      •  Y Done. Some readers might find it a bit TMI though, especially if they click on the links. Hawkeye7 (talk) 05:57, 22 September 2013 (UTC)Reply

Extremely readable article, coming from here in just a month. I'm surprised by the chattiness of the prose in some parts, but on reflection, I think it prevents it from being unreadably dry. Jamesx12345 21:52, 20 September 2013 (UTC)Reply

If you're your own derivative, you must be ex. Just saying. Hawkeye7 (talk) 05:53, 22 September 2013 (UTC)Reply
I've always thought that "jams" must be 1, even without a satisfactory numerological explanation, and some brackets. I'll probably remove that tragic experiment in html anyway, and promote the article now. Good work again. Jamesx12345 11:28, 22 September 2013 (UTC)Reply
