Reference checks, initial pass
The references passed the mechanical check with few problems. In going through the refs, here are the corrections and changes I would suggest:

Note 53, ref name=ZUBAK
This generates a warning ref check. The simple technical solution substitutes URL=http://physics.aps.org/articles/v6/15 for http://prola.aps.org/abstract/PRL/v15/i6/p240_1

However, even the corrected link is too technical for the general reader – I think either of the two alternatives listed below would be fine, and leave it to someone more expert as to which would be more appropriate. Either URL change should be accompanied by the corresponding journal reference (e.g., CHAOS, etc.).


 * http://physics.aps.org/articles/v6/15 which gives a nice overview of the problem for the general reader


 * http://dx.doi.org/10.1063/1.1861554 which provides a more detailed historical perspective by the original author of the article.


 * I really, really don't think that the readers will go looking, but substituted the first article. Hawkeye7 (talk) 08:29, 24 May 2013 (UTC)

Note 13, ref name=VOLSKY
The reference appears genuine, but points to an inappropriate website. Substitute http://www.aulam.org/anxious2.htm#volsky for current URL: http://groups.yahoo.com/group/300PolishSquadron/message/3289?var=1 and update the corresponding reference in the note.
 * Done. Hawkeye7 (talk) 08:29, 24 May 2013 (UTC)

Note 75, ref name=MONTESEARCH
I would replace this reference and slightly reword the paragraph it supports: The Monte Carlo method has become a ubiquitous and standard approach to computation, and the method has been applied to a vast number of scientific problems. In addition to problems in physics and mathematics, the method has been applied to: finance, social science, environmental risk assessment, linguistics, radiation therapy, and sports, ..

Next, in the references section, replace MONTESEARCH with MONTEALAMOS

Ulam Quotations
Comment: Before the recent flurry of edits, which began on 13 May 2013, the article contained two sections of quotations by and about Ulam. There were 14 quotations, documented by 8 distinct references. Both sections have been deleted. I find it hard to believe that nothing from this material should be included in a good article about Ulam. Deer*lake (talk) 18:27, 24 May 2013 (UTC)
 * They are all still there on Wikiquote, which is linked in the article. The section was removed per WP:LONGQUOTE: Do not insert any number of quotations in a stand-alone quote section Hawkeye7 (talk) 19:00, 24 May 2013 (UTC)
 * A comparison of the quotes by and about Ulam with those in Wikiquote shows that the above statement is not true. In fact, of the 33 Wikiquotes, only three appeared in the article.  The "rule" cited above is ambiguous.  Within its context in WP:LONGQUOTE, there is no way it can be used to mandate wholesale deletion of pertinent quotations.  The point is that quotations offer a compact way to introduce relevant information that does not fit well within the text.  For example, Ulam's quoted and referenced declaration "I'm an agnostic." adds dimension to his character, and its deletion leaves two of his categorizations unreferenced.  Similarly, Hans Bethe's quotation,  which has been in the article since 5 May 2005, puts on record his authoritative  opinion on who deserves credit for the H bomb.   Deer*lake (talk) 20:49, 26 May 2013 (UTC)
 * WP:LONGQUOTE is quite clear on this matter: quote sections are prohibited. The quotes should be on Wikiquote. I have inserted Bethe's quotation into the text, although I believe that the text already covered the issue. Hawkeye7 (talk) 21:56, 26 May 2013 (UTC)
 * I'd personally not object to having one or two quotes, but it is a rare practice, and per cited policy, more often frowned upon than not. --Piotr Konieczny aka Prokonsul Piotrus&#124; reply here 12:16, 28 May 2013 (UTC)
 * If the intention of WP:LONGQUOTE is to prohibit quote sections, then it should say so in plain language. In any case, it is part of an essay, Quotations, where the box at the top states: "This guidance essay … is not a Wikipedia policy or guideline."  Deer*lake (talk) 17:13, 28 May 2013 (UTC)
 * I have no opinion about quotations generally. However, for this article I think that the agnosticism quote should be re-introduced (along with its corresponding REF) – otherwise, I agree categorizing Ulam as an agnostic is unsupported. If there is agreement, adding the quote in or at the end of the Holocaust paragraph seems most appropriate, but I'm also open to alternative suggestions for resolving this. Dictioneer (talk) 19:38, 28 May 2013 (UTC)
 * It took a bit of effort to find an appropriate spot, but I have inserted it into the text. Hawkeye7 (talk) 22:11, 28 May 2013 (UTC)

Two more ref issues
Note 35 ref name=MIKEDEATH does not appear adequate to support the sentence, and the sentence appears to be unnecessary. Recommend deleting, but some form of rewording might also work.
 * Removed. Hawkeye7 (talk) 11:54, 28 May 2013 (UTC)

Note 17, name=MCKIBB, does not appear to support the paragraph that references it. Recommend its removal or use in some other part of the article. The statement is adequately supported by fn 5, name=VITA.

Also suggest shorter wording, something like: Knowing nothing of the area, he borrowed a New Mexico guide book. On the checkout card, he found the names of his Wisconsin colleagues, Joan Hinton, David Frisch, and Joseph McKibben, all of whom had mysteriously disappeared.

Dangling phrase
In 1951, after controversy over credit for the H bomb developed, both Teller and Ulam left Los Alamos, which is an indication of their states of minds. The original paragraph stating this has been removed, which leaves dangling the first phrase of Fermi-Pasta-Ulam problem   Deer*lake (talk) 17:35, 28 May 2013 (UTC)
 * I had to look back quite a few revisions to find the missing sentence, and even then I think it had a couple intervening paragraphs. It appears that the reference is to when Teller left for the University of Chicago and Ulam took up a visiting professorship at Harvard in 1951. If this understanding is correct, I suggest the following opening sentence in Fermi-Pasta-Ulam problem: In September 1951, Ulam began a pattern of going on leave as visiting professor to a variety of universities but returning each summer to continue his research. Dictioneer (talk) 19:38, 28 May 2013 (UTC)
 * September 1951 is when Teller left, but I'm not sure exactly when Ulam did. If you insist on deleting the original paragraph, you could just start the FPU section with a statement that Ulam went to Harvard in late 1951.  Although Ulam was often on leave from Los Alamos, I don't think a pattern had been established at this early date.  Deer*lake (talk) 21:01, 28 May 2013 (UTC)
 * I have restored part of the original paragraph, which was deleted because it was unsourced, and ran off-topic on talking about Teller's subsequent activities. Ulam departed Los Alamos on 13 September, three days after Teller submitted his resignation. Hawkeye7 (talk) 21:40, 28 May 2013 (UTC)

Impact and legacy edits

 * Delete the following 2 sentences as non-relevant to this biographical article: Alwyn Scott was its first director, and Kac was chairman of its first external advisory committee, on which Martin Kruskal also served. The purpose of CNLS is to continue the laboratory's tradition of work in nonlinear science, which began with FPU, but which also includes Mitchell Feigenbaum's important work in chaos and fractals (1975).

 * For the biology legacy, substitute the following as a stand-alone paragraph:
 * old graf: In 1985, Beyer, Sellers, and Waterman reviewed Ulam's contributions to theoretical biology in terms of his work in cellular automata theory, population biology, pattern recognition, and biometric spaces. In much of this work, Ulam attempted to define distance metrics, which differ from Euclidian distances, but which are appropriate measures in the context of molecular  biology.  In 1982, Ulam gave an overview of these ideas in his Gamow memorial lecture at the University of Colorado.  His Los Alamos colleague, Walter Goad, has described their impact on sequence analysis.
 * new graf: Ulam's work on non-Euclidean distance metrics in the context of molecular biology made a significant contribution to sequence analysis and his contributions in theoretical biology are considered watersheds in the development of cellular automata theory, population biology, pattern recognition, and biometrics generally. Colleagues noted that some of his greatest contributions were in clearly identifying problems to be solved and general techniques for solving them.

 * I would remove the first sentence of the next paragraph as not relevant to this biography, and reword the next 2 sentences: Fermi, learning of Ulam's breakthrough, devised an analog computer known as the Monte Carlo trolley, later dubbed the FERMIAC. The device performed a mechanical simulation of random diffusion of neutrons. As computers improved in speed and programmability, these methods became more useful. In particular, many Monte Carlo calculations carried out on modern massively parallel supercomputers are embarrassingly parallel applications, whose results can be very accurate..
 * There may be an argument for keeping it as is, but at this point, I think a substantial edit is needed.
 * Agreed. Hawkeye7 (talk) 13:10, 30 May 2013 (UTC)

Infobox, misc
I am not a fan of infoboxes and consequently not very familiar with best practice. I've had a look at the MOS and think these consistent with its guidance, but nonetheless consider the following changes as open to discussion.


 * In the Fields section of the infobox, I think Physics is a “must-add”, and Biology and Computer Science also seem appropriate additions.
 * Done. Ulam considered himself a mathematician. Hawkeye7 (talk) 19:46, 1 June 2013 (UTC)
 * The sentence at the end of Known For seems unnecessary for the infobox and repeats the last sentence of the introductory paragraph. I recommend deleting it.
 * Removed. Normally everything in the legacy section would be listed. Hawkeye7 (talk) 19:46, 1 June 2013 (UTC)
 * I noticed that the Teller-Ulam design suggestions listed above were not implemented. That's fine and certainly not a deal-breaker, but please add a note to the section documenting why the changes would not improve the article. If they simply got missed in the clutter, feel free to implement them and make a note.
 * Implemented. They were just overlooked. Hawkeye7 (talk) 19:46, 1 June 2013 (UTC)
