Your recent changes to Ununoctium

Hi! I wanted to ask why you decided to remove information from Ununoctium without specifying a reason. Was it incorrect? SkyLined (talk) 23:15, 25 March 2008 (UTC)[reply]

On the noble gases talk page we argued that Ununoctium should not be considered a noble gas until there is evidence that it has similar properties to the six other elements of group 18. Thus I removed the "(noble gases)" in the Uuo introduction.--Roentgenium111 (talk) 23:37, 25 March 2008 (UTC)[reply]

That makes sence then. I've tried to adjust the wording on the page to put the statement around it potentially not being a noble gas nearer the statement that puts it in group 18, but couldn't think of anything that made sense. I either end up duplicating information or moving something else that then makes no sense... oh, well. Thanks for the info! SkyLined (talk) 10:20, 26 March 2008 (UTC)[reply]

Template:Natural satellites

Hi,

If we describe the table as having dwarf planets in bold, then your revert is fine. But currently we say that bold = hydro. equilibrium. Objects aren't in hydro. equilibrium "by definition" because they're dwarf planets, they're dwarf planets by definition because they're in hydro. equilibrium. Eris is assumed to be in hydro. equilibrium because it's more massive than Pluto, and Makemake and E61 are assumed it be in hydro. equilibrium because their absolute magnitudes are less than 1. Many others are assumed to be in hydro. equilibrium as well, but we have no problem italicizing them. What we could do is say that bold = hydro. equilibrium or an assumption of hydro. equilibrium for naming purposes. However, if we did that, we would need to bold E61 as well. Or we could say bold = hydro. equilibrium or accepted as a dwarf planet by the IAU, in which case we would not need to bold E61. kwami (talk) 19:42, 15 September 2008 (UTC)[reply]

I don't quite get your point. My reasoning is the following: 1. IAU classifies Eris, Pluto and Makemake as dwarf planets. 2. By IAU, an object is a dwarf planet, if it has achieved hydro. equilibrium (+not having cleared the neighbourhood). It follows logically from 1. and 2. that Eris, Pluto and Makemake have achieved hydro. equilibrium (in IAU's opinion, of course). I don't know any source which disagrees with this. However, IAU does not (yet) classify EL61 as either dwarf planet or as having reached hydrostatic equilibrium. --Roentgenium111 (talk) 12:26, 16 September 2008 (UTC)[reply]

heaviest element

If you could find a RS for the claim that 170-210 is the theoretical limit of elements, that would be appreciated. As would the reasoning, which you hinted at Talk:Extension_of_the_periodic_table_beyond_the_seventh_period. It looks like there may be 3 issues: the physical limits due to drip lines, tied up w the presumed Island of Stability, and the theoretical limits for neutral atoms and for nuclei. Thanks, kwami (talk) 11:54, 15 May 2009 (UTC)[reply]

What do you mean by "RS"? I gave a reference for this statement in the article (currently reference [4], Encyclopedia Britannica). I must admit I don't know the reason why this is believed to be the limit. --Roentgenium111 (talk) 21:33, 15 May 2009 (UTC)[reply]

WP:RS. The EB isn't much more accurate than Wikipedia; we certainly don't want to use them for esoteric claims about physics if we don't have to. I agree it's better than a bald claim, but there's no way to tell if the info is peer reviewed, dated, rejected, or adjusted. I can ask at the physics project. kwami (talk) 01:19, 16 May 2009 (UTC)[reply]

I don't see what's "esoteric" about this claim. Also, according to WP:RS:

Tertiary sources such as compendia, encyclopedias, textbooks, and other summarizing sources may be used to give overviews or summaries, but should not be used in place of secondary sources for detailed discussion.

So, since I only used it for an "overview" statement and we (unfortunately) don't have secondary sources available, I think the use of EB as a reference in this situation is quite appropriate. --Roentgenium111 (talk) 17:55, 18 May 2009 (UTC)[reply]

It's acceptable lacking anything better, just not terribly reliable. Physics could easily have moved on since then, esp. considering how sensitive such estimates are to the models used. Considering the general unreliability of any encyclopedia, including the EB, it would be better to get something peer reviewed that can be verified by the reader. kwami (talk) 20:19, 18 May 2009 (UTC)[reply]

H1N1 Outbereak in Norway

I cannot see what you mean by deleating irrelevant information, as what you deleted is highly relevant to a pandemic in Norway, it is all numbers by the Norwegian government, and should be kept. —Preceding unsigned comment added by Notelitten (talk • contribs) 10:38, 6 June 2009 (UTC)[reply]

The article I deleted this information from covers all the 200 countries in the world, so we can only give an overview of the situation in each country. The Norway chapter was one of the longest, so I tried to shorten it. (I did the same for my own country Germany, by the way). But you may create a separate article "Swine flu outbreak in Norway" and put the deleted information in there if you think it noteworthy, and put a link to it in the main article. --Roentgenium111 (talk) 17:08, 6 June 2009 (UTC)[reply]

Overpopulation - your question regarding my charts

Hi Roentgenium111 - just to let you know that I noticed your question yesterday, indirectly addressed to me, that you posted last November on Overpopulation Talk.

Perhaps another time you could also mention it on my talk page so it's easier for me to notice? Anyhow please do take a look and see if I have now put your mind at rest?

Many thanks Barryz1 (talk) 21:44, 7 January 2010 (UTC)[reply]

Hi again Roentgenium111, in response to your further observation & questions I put in a whole lot more time and effort to reply. Please do take a careful look through and give me your thoughts. Hopefully we are now in agreement but if not I'd be very interested indeed to know your detailed thoughts on the subject; Population falls due to Plague shown on Charts.

Hi, Roentgenium111. I'm a native Vietnamese and maybe I would make wrong spelling and grammar.

German federal election July 1932

I did the best I could, but your revision is better. I just happened to look at the article and happened to notice the explanation of that edit, that the sentences being deleted were "meaningless" when they were anything but. The sentences read like they were written by a German native speaker and they also assumed a certain level of knowledge about parliamentary government that is not possessed by most Americans, so I was trying to restore the information in a way that it would not get deleted again. Marrante (talk) 18:49, 6 July 2010 (UTC)[reply]

Yes, I imagined something like that. It was good you made that edit, since this important fact definitely belongs in the article. In case you were worried, I didn't want to criticise your edit with my edit summary. I just wanted to give reasons for mine so that it would not be reverted. --Roentgenium111 (talk) 14:49, 27 July 2010 (UTC)[reply]

I just finally made it back here to see your reply to my post above. Thanks for explaining your edit because I did think there was an implied criticism a bit (because of the quotes around "central point", which can be sometimes be a kind of sarcasm) but the edit itself really did explain it better and you were right about what I had written. Anyway, I made it back here again because I wanted to thank you for restoring that sentence. I saw the deletion and explanation, but hoped you'd fix it and felt you'd do a better job than I would anyway (which you did). I'm having trouble enough right now, just typing on a schleptop kezboard. ;-> Marrante (talk) 21:41, 1 August 2010 (UTC)[reply]

By way of a thank you, I will tweak your comment. (Would that you could return the favor, but we're not supposed to write in other languages here. Or more accurately, would that my German were as good as your English!) Marrante (talk) 21:46, 1 August 2010 (UTC)[reply]

If you have a scientific reference for the sentence I deleted, feel free to re-add it.

Elements 109, 110, 111

While I agree that the chemical properties of these elements have not been found out, IUPAC specifically defines the transition metals to be elements in groups 3-12 ([1], p. 51), so Mt, Ds and Rg would be transition metals regardless of their chemical properties by this definition. (For the systematically-named elements, IUPAC does not mention anything like this, so the current colouring is correct. I would think that [2] is not a reliable source.) Lanthanum-138 (talk) 07:41, 3 March 2011 (UTC)[reply]

Thanks for your comment. But you're not quite correct: On that page, IUPAC says that these elements are "commonly referred to" as "transition elements" - so 1. they don't call them thus themselves (the list of IUPAC-appproved element categories on p.51/52 does not include this category), and 2. the notion of "transition element" naturally does not imply anything about chemical properties, while "transition metal" (which is the term used in the table I recently edited) implies that they're all metals, which is yet unknown. So I'd say that 109-111 are transition elements by definition, but not necessarily transition metals. (BTW, I'd rather oppose changing the category name in the table to "trans. element" since the colouring is supposed to show chemical similarities, not pure formalities.)

Finally, Wikipedia does not in general consider IUPAC as the most authorative source. Otherwise, we would have to stop the periodic table at copernicium (112), since this is the last element whose discovery has been acknowledged by them. (I considered doing this some years ago, but it was met with strong resistance by other WP editors.) --Roentgenium111 (talk) 12:31, 3 March 2011 (UTC)[reply]

Oops - this is what I get for not reading carefully. However, since the current periodic table at Template:Compact periodic table is relatively stable, we may have to bring this up at WT:ELEM. Lanthanum-138 (talk) 12:17, 6 March 2011 (UTC)[reply]

BTW, can you give me a link to the discussion where you considered stopping the periodic table at Cn some years ago? Double sharp (talk) 10:38, 10 February 2012 (UTC)[reply]

I think it was this discussion: Wikipedia_talk:WikiProject_Elements/Archive_8#Proposal_to_remove_undiscovered_elements_from_the_periodic_table. I was editing as an IP back then.

(Thanks for finally establishing the "uncolouring" of 109-111, BTW - I had already given up on it before since my edits had been continuously reverted without explanation.) --Roentgenium111 (talk) 15:35, 10 February 2012 (UTC)[reply]

High Earth orbit

Excerpt from the source:

Definition: A High Earth Orbit is any orbit above geosynchronous (above 35,786 km). A Highly Elliptical Orbit is an orbit of low perigee (about 1000 km) and a high apogee over 35,786 km)

Excerpt from the article:

A High Earth Orbit is a geocentric orbit whose apogee lies above that of a geosynchronous orbit (35,786 kilometres (22,236 mi)). Highly Elliptical Orbits are a subset of High Earth Orbits.

Are you suggesting that the source say that both the perigee and apogee of a High Earth Orbit are above geosynchronous ? If not what exact claim of the article do you think is unsupported (or contradicted) by the source ? Bomazi (talk) 20:42, 4 April 2012 (UTC)[reply]

An "orbit above geosynchronous" to me means that at least the mean orbital distance (if not the perigee) is above 35,786 km, not just the apogee.--Roentgenium111 (talk) 21:00, 4 April 2012 (UTC)[reply]

Extended periodic table limit

Previously there seemed to be a large consensus that elements higher than Z=173 cannot exist which seemed to be backed by large number of scientific articals. Why is the limit now z=218? Robo37 (talk) 09:52, 5 December 2012 (UTC)[reply]

I don't know; I haven't edited that article for a year, when it was still 173. You'd best ask this question on the article's talk page, or ask the editor who actually made that change. --Roentgenium111 (talk) 13:47, 5 December 2012 (UTC)[reply]

173 was based on a misunderstanding of the theoretical calculations. While it's true that at Z>173 the 1s states enter the negative continuum, that in itself does not stop the atom from existing. Instead the atom remains stable and bound if the 1s shell is not ionized, and the 1s states mixed with the states in the negative continuum to form a bound "resonance" state.

Could PH2 b Be Potentially Habitable - Or Not?

Copied from Talk:PH2 b#Could PH2_b Be Potentially Habitable - Or Not:

Could PH2 b Be Potentially Habitable - Or Not?
[edit]

Apparently, the confirmed exoplanet PH2 b is in the "Habitable zone".(< ref name="arXiv-20130103">Wang, Ji (January 3, 2013). "Planet Hunters. V. A Confirmed Jupiter-Size Planet in the Habitable Zone and 42 Planet Candidates from the Kepler Archive Data". arXiv:1301.0644v1 [astro-ph.EP]. {{cite arXiv}}: Unknown parameter |accessdate= ignored (help); Unknown parameter |coauthors= ignored (|author= suggested) (help); Unknown parameter |journal= ignored (help); Unknown parameter |url= ignored (help)CS1 maint: date and year (link)</ref>
One cited reference in the PH2 b article suggests that a "Jupiter-size world" (PH2 b?) could "potentially be habitable."< ref name="Space-20130113">Howell, Elizabeth (January 13, 2013). "Amateur Astronomers Discover 42 Alien Planets". Space.com. Retrieved January 13, 2013.</ref>
This was originally stated in the PH2 b Wikipedia article but has been reverted by two editors: Roentgenium111 with a reason and by Nergaal without a reason. The reason for the reversion given by Roentgenium111 is as follows: ("correct - the absurd habitability claim is (self-)contradicted by the space.com article itself: "Ph2 b is considered much too large to host life." It could only have habitable moons...")
However, the statement ("Ph2 b is considered much too large to host life.") seems to have been written by the magazine writer (Elizabeth Howell) and does *not* seem to have been presented by the scientists: after all, there is no citation for the sentence; Ms Howell, the writer, does not quote the scientists and a search of the original arXiv article does not reveal any mention of the notion (directly or indirectly) as far as I can see.
For myself at the moment, the notion of a planet being in the "Habitable zone" may make the existence of life (as we know it) more likely - such a planet being large (or even being gaseous) should not make hosting life forms less likely. Is there something I may be overlooking?
Any help in better understanding this issue would be greatly appreciated - in any case - Enjoy! :) Drbogdan (talk) 02:13, 15 January 2013 (UTC)

"Indentions"

I'm puzzled about a piece of this edit, wherein you readded italics to the non-planets in the list. Is there a (good) reason why those should be italicized? --Izno (talk) 04:15, 24 May 2014 (UTC)[reply]

My intention for the italics was just to keep them visibly distinct from the actual planets in the list (but I wouldn't mind distinguishing them in some other way). Is there a reason why they shouldn't be italicized? --Roentgenium111 (talk) 21:44, 24 May 2014 (UTC)[reply]

Because we don't italicize things for no reason? WP:ITALICS explains when it is a good reason. (Besides, I personally see no reason to delineate between planet and non-planet....) --Izno (talk) 22:44, 24 May 2014 (UTC)[reply]

Actually, MOS:EMPHASIS suggests using italics for emphasis. It's also used for distinction in exactly the same way in other articles like List of sovereign states and dependent territories by fertility rate (using italics for dependent territories, as opposed to sovereign states). In this case, a distinction is reasonable because the article is only about terrestrial planets, not the Moon or some asteroids; the latter are (presumably) only included for comparison purposes. If we don't emphasize this, the non-planets should be removed completely because they're off-topic. --Roentgenium111 (talk) 13:55, 25 May 2014 (UTC)[reply]

I actually have no objection to removing the non-planets; it does seem odd to me to include them in a list on a page about planets. :^) --Izno (talk) 02:28, 28 May 2014 (UTC)[reply]

Tunisian election

Hi Roentgenium, thanks for your edit at Tunisian presidential election, 2014. Could you also update the source? The one currently in use only mentions preliminary results. Thanks! Abjiklɐm (tɐlk) 17:54, 15 December 2014 (UTC)[reply]

Hi Abjiklam, thanks for notifying me. I don't have another source, unfortunately, I thought those results were final. But I think my edit can stand as is, it's still an official document giving exact, even if preliminary, results. (Usually preliminary official results don't change by much any more.) It's not just "early results indicating" the run-off candidates, Marzouki and Essebsi are already named explicitly at http://www.isie.tn/ . --Roentgenium111 (talk) 10:17, 17 December 2014 (UTC)[reply]

I understand, but the current source says "Preliminary results in the country's first presidential ballot since the uprising are expected later on Monday." That's hardly an official document giving exact results. Maybe directly referencing the ISIE would be better. Abjiklɐm (tɐlk) 17:26, 18 December 2014 (UTC)[reply]

You're right, I've copied the ISIE source there instead. --Roentgenium111 (talk) 14:25, 19 December 2014 (UTC)[reply]

Kepler-438b - near or super Earth sized?

Thanks again for your recent edit on the Kepler (spacecraft) article - depending on the definition of a Super-earth, perhaps Kepler-438b (r = 1.12earth) is near-Earth-sized instead? - possibly relative quote => "Kepler-438b and Kepler-442b, are less than 1.5 times the diameter of Earth. Kepler-438b, 475 light-years away, is 12 percent bigger than Earth and orbits its star once every 35.2 days."^[1]^[2] - in any case - Enjoy! :) Drbogdan (talk) 15:01, 12 January 2015 (UTC)[reply]

^ Overbye, Dennis (January 6, 2015). "As Ranks of Goldilocks Planets Grow, Astronomers Consider What's Next". New York Times. Retrieved January 6, 2015.

Yes, Kepler-438b is certainly near-Earth-sized (unlike the largest planets in the list). That's why I put the "super" in brackets in a subsequent edit. Feel free to reword the text for clarity. But I don't like wikilinking "near-Earth-sized" to "terrestrial planet" for any of the planets - unless we have a good mass estimate, even 438b might be a gas dwarf like Kepler-138d is... Terrestrial (exo)planets are not defined by size, but by their composition. --Roentgenium111 (talk) 15:12, 12 January 2015 (UTC)[reply]

@Roentgenium111: Thanks for your comments - *maybe* one possible caption for the image is the following:

"Confirmed near-Earth-sized (Kepler-62f, Kepler-186f, Kepler-438b, Kepler-442b) and super-Earth-sized (Kepler-62e Kepler-296e, Kepler-296f, Kepler-440b) exoplanets in habitable zones."

other possible image captions welcome of course - should note that the related exoplanets with associated "r/earth" are as follows (those less than r = 1.50earth are noted): Kepler-62e/1.61, Kepler-62f/1.41*, Kepler-186f/1.11*, Kepler-296e/1.75, Kepler-296f/1.79, Kepler-438b/1.12*, Kepler-440b/1.86, Kepler-442b/1.34* - in any regards - Thanks again for your comments - and - Enjoy! :) Drbogdan (talk) 19:22, 12 January 2015 (UTC)[reply]

@Roentgenium111: BRIEF Followup - might just stay with the image caption in the image itself =>

"Confirmed small exoplanets in habitable zones. (Kepler-62e, Kepler-62f, Kepler-186f, Kepler-296e, Kepler-296f, Kepler-438b, Kepler-440b, Kepler-442b)."

maybe best after all - let me know if otherwise of course - Thanks again for your comments - and raising the issue - Enjoy! :) Drbogdan (talk) 21:58, 12 January 2015 (UTC)[reply]

Both captions look good to me. But Kepler uses 1.25 R_E as the lower limit for super-Earths, not 1.5 R_E. (It is estimated that all planets smaller than about 1.5-1.6 R_E are more likely than not terrestrial [4], but there's no clear dividing line.) --Roentgenium111 (talk) 11:58, 13 January 2015 (UTC)[reply]

@Roentgenium111: Thanks for your comments - Yes - agreed - seems there's an issue with the lower limit of Earth mass (M_E) and Earth radius (R_E) for Super-Earth exoplanets (ie, the upper limit seems to be "10" M_E but the lower limit seems to vary between "1" and "5" M_E, according to Super-Earth#Definition - which may be related to the R_E in some ways) - seems the image caption above noting "small" may be best, and avoids the R_E issue, and has been used to update relevant image captions re the image - hopefully this is *entirely* ok with you - let me know if otherwise of course - Thanks again for your comments - and - Enjoy! :) Drbogdan (talk) 13:51, 13 January 2015 (UTC)[reply]

"Small" is fine, but duplicate to the "caption" contained in the image. It seems the image lists all HZ planets below 2 R_E? So we could write "Confirmed small exoplanets (below 2 R_E) in habitable zones" to give extra information without worrying about the murky super-Earth definition. But I would also like to stick with something like "Confirmed Earth- and super-Earth-sized exoplanets in habitable zones" since it may be more "intuitive" for laypeople - it still doesn't require us to distinguish Earths and super-Earths in the caption if we can't agree on the dividing line. --Roentgenium111 (talk) 10:11, 14 January 2015 (UTC)[reply]

@Roentgenium111: Thanks for your comments - *entirely* ok with me if the image caption is presented as you suggested =>

"Confirmed Earth and super-Earth sized exoplanets in habitable zones. (Kepler-62e, Kepler-62f, Kepler-186f, Kepler-296e, Kepler-296f, Kepler-438b, Kepler-440b, Kepler-442b)."

TRAPPIST-1

I reverted your edits because all the sources seem to agree it is a brown dwarf that I can find. The brown dwarf article notes " At the high end of their mass range (60–90 MJ)..." when discussing them so 83 MJ would seem to be at the high end but not out of range absolutely. I am not a very knowledgeable astronomer though, so if there is a good source please do cite it and restore them. Before the starbox was added the mass wasn't posted. You may well be right OR it may be some of the info in the starbox is wrong I added some of it and could have messed something up, but we should be sure the changes we make are the right ones and based on good sources. Glad to see others are interested though seems like pretty cool stuff. Phil (talk) 13:57, 3 May 2016 (UTC)[reply]

The lead of the article Brown dwarf gives "an upper limit around 75 to 80 Jupiter masses". Can you give a specific source which states that TRAPPIST-1 is a brown dwarf? I checked several sources in the article, and they all say "ultracool dwarf" or "dwarf star", neither of which implies brown dwarf (the Sun is a dwarf star too). --Roentgenium111 (talk) 15:29, 3 May 2016 (UTC)[reply]

Italian constitutional referendum

Sorry for this. You're right, my fault. Yet, I think the paragraph is not optimally worded. "As well as effectively abolishing the current Senate, the package also included a new electoral law". The term "package" is poor, as the paragraph (as you pointed out) describes a general political direction rather than a specific body of reforms (to which the term "package" would be more fit). Likewise, the phrase "effectively abolishing the Senate" also seems to refer to a specific reform, and reinforces the misunderstanding of the term package. Moongateclimber (talk) 08:25, 18 November 2016 (UTC)[reply]

It's fine, I'm glad you agree. I wouldn't mind replacing "package" by "program" - that's how it's called in the previous sentence. But I do think the two reforms belong closely together. I think they were announced together by Renzi, and together they allow the plurality party to govern on its own w.r.t. most laws. The senate reform only took a longer time because it's a constitutional change, while the electoral law could be changed by simple majority of the Parliament.--Roentgenium111 (talk) 11:32, 18 November 2016 (UTC)[reply]

Polgar

Hi, would you please undo your revert on László Polgár. The source is entirely correct, see Interzonal. The final match was only stage 4 of the World Championship. Guido den Broeder (talk) 13:19, 5 May 2017 (UTC)[reply]

Thanks for coming here to discuss. Even if the interzonal is considered part of the World Championship, there is no mention of Susan Polgar qualifying for an interzonal in our articles World Chess Championship 1987 or World Chess Championship 1990, which both give detailed results for the corresponding interzonals in 1985 resp. 1987.

As I wrote in my edit, we need a better (chess-related) source, not a psychology paper, for such a strong claim of gender discrimination. Both of the championships mentioned above are clearly called "World Chess Championship" both in Wikipedia and in the sources given there, so Psychology Today's claim of it being called the "'Men's World Championship'" is evidently false. Thus it's clearly an unreliable source with respect to chess competition details. --Roentgenium111 (talk) 16:48, 11 May 2017 (UTC)[reply]

Psychology Today is a reliable source, which means that they have a good reputation for fact-checking. It's a fitting source for this particular article. Wikipedia, on the other hand, is inherently unreliable and cannot be used as a source. It contains a high percentage of errors, including a failure to mention that it used to be the men's world championship. Susan Polgar qualified for the Zonal Tournament in her region, which was the first phase of the championship. Except that she wasn't a man. Guido den Broeder (talk) 17:59, 11 May 2017 (UTC)[reply]

I don't know if Psychology Today is generally considered reliable, but it's clearly not specialised on chess, so WP:CONTEXTMATTERS applies: "Information provided in passing by an otherwise reliable source that is not related to the principal topics of the publication may not be reliable; editors should cite sources focused on the topic at hand where possible." As I said, it's not just Wikipedia stating that it was called "World Chess Championship", that name is sourced by chess-related references: e.g. [5], [6].

And how do you know that "Susan Polgar qualified for the Zonal Tournament in her region, which was the first phase of the championship"? The Psychology Today article doesn't give such detailed information, it simply claims she qualified for the World Championship, which would be rather misleading if she only qualified for the first of four stages. If you have another source for this, please give it, so that we can resolve this. --Roentgenium111 (talk) 18:54, 11 May 2017 (UTC)[reply]

No, it is not mentioned 'in passing'. You can, however, find the information here online as well, and in Susan's books, all the international chess magazines, the proceedings of the 1986 FIDE congress, etcetera. I know because I was one of many chess players to successfully press the FIDE into changing the name and nature of the Men's World Chess Championship, allowing women to participate from then on.

On China's "1.5" child policy

Greetings Roentgenium111, Was glad to see your Oct. 10 abbreviations to the One Child Policy intro, and I agree that China did not have a uniform "1.5" child policy after the major loosening of one-child restrictions in the mid 1980s, but I disagree that the loosening was step by step after that (there was essentially no loosening of quotas by the central government between the mid 1980s and 2013 - the apparent loosening after 2000 was due instead to increasing proportions of parents who qualified for existing exemptions). There is plenty of original research to support these assertions, and I would like to re-write a single sentence for the intro with appropriate refs to emphasize that "the" one-child policy really is a misnomer - it was not so strict for most of its existence. BTW - I think this entry will require a lot of updating in the near future. ps - you may note that I am a rather new editor here - still trying to figure out some of the basics of editing, talk pages (just watched a helpful video), etc., so feel free to offer suggestions if you wish.Despoina8 (talk) 09:45, 14 October 2018 (UTC)[reply]
