All other encyclopaedias seem to point to Loas Angeles as the place where he died. Can someone check this? I don't not want to alter Cambridge without a written (printed) high class source. --DrJunge (talk) 06:30, 20 July 2008 (UTC)[reply]

According to [1], Libby tried to find spontaneous fission in 1939 and found the upper limit of its partial desintegration constant to be 10^-22 s^-1. --217.21.43.22 (talk) 17:23, 8 October 2014 (UTC)[reply]

• I propose to undertake this review and will read through the article in detail shortly. Cwmhiraeth (talk) 17:37, 20 October 2015 (UTC)[reply]

First reading

The first half of the article has a number of careless errors while the second half is much better:

• "He sided with Edward Teller on pursuing a crash program to develop the hydrogen bomb, help the Atoms for Peace program, and defended the administration's atmospheric nuclear testing." - the tenses in this sentence are a bit muddled.

  Y Corrected. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "When he was five, Libby's parents moved to the Santa Rosa, California" - "the" not needed.

  Y Deleted word. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "When he was five, Libby's parents moved to the Santa Rosa, California. Libby began his education in a two-room Colorado schoolhouse." - These two sentences need to be reversed to make them chronological.

  Y Done. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "... independently of the work of George de Hevesy and Max Pahl" - I suggest you put this phrase at the beginning of the sentence.

  Y Done. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "He became and assistant professor of Chemistry there in 1938" - typo.

  Y Corrected. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "and the fissile uranium-235 made up only one-hundred and fortieth of natural uranium." - Couldn't you express this as a percentage, or say "less than one percent"?

  Y Done. I thought one part in 140 was easier for people to grasp than 0.7% Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• " a heavier one. In fact," - sentence structure.

  Y Joined sentences together. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "In addition to the developing a suitable barrier," - typo.

  Y Deleted word. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "had to assist in design an industrial gaseous" - a couple of words missing here.

  Y Added words. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "Only a few tests by Libby indicated that the Norris-Adler they were working indicated that it would." - This sentence is a bit garbled.

  Y Done. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• Wikilink or explain "Norris-Adler"

  Y That's an idea. Done. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "He remained confident that with an all-effort," - "all-out-effort"?

  Y Added words. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• He was working on using gaseous diffusion and finding problems. It is not clear to me whether he was successful in the end, or whether the isotopes were eventually separated by a quite different method, in a new process developed by Kellex.

  Y He was successful in the end, but the the isotopes were eventually separated by a quite different method, in a new process developed by Kellex Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]

• "a professorship in Chemistry Department at the " - typo.

  Y Corrected. Hawkeye7 (talk) 21:32, 20 October 2015 (UTC)[reply]
