注意到阁下在Special:Diff/76079896引用了一段短片作为来源,但该来源不属维基百科可用的WP:可靠来源(例如因为非经正式途径出版,内容亦未经审核),因为不能加入。敬希垂注,祝编安!——留言2023年2月22日 (三) 22:37 (UTC)[回复]

阁下可以引用已出版的论文、书籍作为来源,而假如影片是实验录影/数据模拟之类,文字难以表达,但有助读者理解主题的影片,符合Wikipedia:外部链接要求的话亦可加入作为外部链接(而非引用作“来源”),但单纯朗读的影片,其资讯并非必须以影片格式为载体,因此不必链接,而应引用其朗读内容的原始出处(倘若出自可靠来源)。——留言2023年2月22日 (三) 22:43 (UTC)[回复]
I added a ref to replace the original one.

既然此短片是adapted from另一已引用的来源,似乎未见重复引用短片(因为也是仅有朗读)的理由。引用自己著作时请留意在维基百科上WP:SELFCITE的提醒,例如此类情况下在下(&)建议避免引用该短片,以免给予其他编者一种为推销影片而引用的观感,感谢。——留言2023年2月23日 (四) 00:03 (UTC)[回复]
Hello, the video added discussions for the analogy with skiing and kayaking in both English and Chinese versions.
It should not be simply viewed as "仅有朗读". Please let me know if I can be helpful. Thanks, -Bowen--Bwshen留言2023年2月23日 (四) 00:08 (UTC)[回复]
不太认同阁下的见解,因为虽然有滑雪片段,但该片段与主题无关,与主题相关的提到skiing和kayaking的内容实质上仍是依赖旁白朗读文字(所以在下说“仅有朗读”),不能算是善用了“影片”此一媒体的表现方式,而应直接使用文字描述。——留言2023年2月23日 (四) 00:19 (UTC)[回复]
Skiing was first used to discuss SDIC (i.e., butterfly effect) by Prof. Lorenz (1993). We cited and added discussions in https://www.mdpi.com/2073-4433/13/11/1892.
Please let me know. Thanks.--Bwshen留言2023年2月23日 (四) 00:23 (UTC)[回复]
直接引用该论文,会比引用影片更加符合WP:可供查证方针的要求。——留言2023年2月23日 (四) 00:29 (UTC)[回复]
A current trend is to provide a video clip to support the contents in paper.
Please see the strategy of MDPI Encyclopedia. As mentioned, the new reference was posted by MDPI Encyclopedia.
Why? For example, "skiing" was used in Lorenz (1993). Many readers were not aware of it.
Shen et al. (2022) extended the concept to include kayaking and used skiing and kayaking provided an analogy.
A staff of MDPI Encyclopedia already "reviewed" it.
Please let me know if you have additional questions or comments. Thanks, -Bowen--Bwshen留言2023年2月23日 (四) 00:36 (UTC)[回复]
(?)疑问“the new reference was posted by MDPI Encyclopedia.”MDPI的确有一本peer-reviewed journal称为 Encyclopedia,但影片似乎只是发布于"Encyclopedia Pub",是user-generated content collection platform[1]而非peer-reviewed journal?假若如此,其"review"与传统审稿相比如何?(举例arxiv preprint亦要经"moderation"才能上线但WP:可靠来源指引订明此种程度的review不能使arxiv成为可靠。)另外不太确定阁下“Why? For example, "skiing" was used in Lorenz (1993). Many readers were not aware of it.”一句是指not aware of the fact that "skiing" was used in Lorenz (1993)还是not aware of what skiing is,若是后者,应考虑使用WP:内部链接或以WP:注脚说明,让读者在skiing和kayaking条目找到插图或影片,与是否在蝴蝶效应引用来源无关。——留言2023年2月23日 (四) 01:13 (UTC)[回复]

感谢澄清Encyclopedia pub和MDPI encyclopedia的关系。但尚未明白阁下所指需要引用此影片的理由为何,既然影片是同作者“根据peer reviewed的文章制成”,而已引用该论文,重复引用影片似乎不会增加可信性,反而可能属于应避免的WP:CITEBOMB“大量的引注仅仅指向一个事实⋯⋯引入的来源往往只是其他来源的转述”情况。
另一(?)疑问,Lorenz ref 13似乎未见提及bounded或finite,是否不能用于佐证“轨迹在有限范围内的特性,可由蝴蝶有限的双翼所显示”句?假如ref 13不能佐证该句,亦应移除段尾的引注13,保留段中间Lorenz观点的引注13即可。
(与编辑相关的讨论,在下倾向于维基百科公开进行,以便其他编者检视。)——留言2023年2月23日 (四) 23:33 (UTC)[回复]
哈啰,该影片整理了"几篇文章",是一个精简但"自我完整"(self contained)的版本,用来介绍混沌。譬如说,混沌系统的二个重要特性为:解的有界性,和正的Lyapunov exponent(LE),这两个同时成立,才能表示混沌。一个线性系统,y "=ay, a>0。可以有正的LE,但解不是无界的,因此不是混沌系统。该民谣应该属于这里种情况。我们文章内有详细讨论。许多人,没有时间阅读我们的文章。因此,我们提供一个精简的语音版本。阁下,可以审阅内容,和我们2022的两篇文章比较。若有疑虑,请指教。又,电话讨论可能比较有效。--Bwshen留言2023年2月24日 (五) 01:56 (UTC)[回复]

其实中文系版本蝴蝶效应的图一,需要被修正。有机会可以聊聊。--Bwshen留言2023年2月24日 (五) 03:17 (UTC)[回复]
感谢说明引用影片的理由,的确有一定意义。(虽然对是否符合维基百科当前的“可靠”定义仍存疑问,但可以留待日后再考虑。)虽然整理几篇文章的二手来源为维基百科所重视,但已引用的ref 10的subsection 3.1似乎是整理了同样几篇文章,甚至更多,而影片内容大致上就是对应该节?如此“整理了"几篇文章"”似乎不是重复引用的理由。从百科全书引注方面考虑,已有详细原文,自不必再引用精简的语音版本,若有需要可考虑放在WP:外部链接
关于另一问题,在下不是质疑阁下文章内对民谣情况的定性,也不是质疑“轨迹在有限范围内的特性,可由蝴蝶有限的双翼所显示”(句1),但维基百科的引注规则是,除了scientific accuracy,还着重WP:非原创研究,还望阁下理解。该方针规定,对原始文献的诠释也需要引用二手来源,假若Lorenz 2008 (ref 13)不能直接支持句1而ref 10可以直接支持(不论是原创观点抑或对ref 13等来源的总结皆可),则句1应引用ref 10而非ref 13,所以需要向阁下请教是否属于此情况。——留言2023年2月25日 (六) 00:55 (UTC)[回复]
再者该网站收录"user-generated content collection platform for researchers with additional contributions published on scientific websites by competent experts"[2],除非该短片有经过编审流程,否则user-generated content按WP:可靠来源一般也要避免使用(维基百科对arxiv也是同样处理),已有更好来源(期刊)佐证同一语段的情况下,不应采用较不可靠的来源。——留言2023年2月23日 (四) 00:14 (UTC)[回复]

维基中文版"蝴蝶效应"的讨论,有许多问题。首先,图一,最起码的修正:将attractor 改为trajectory。更重要的是,其定义不准确。经由讨论,显示,你至少同意劳伦兹2008年的看法。有关蝴蝶效应,请参考劳氏1993出版的书。而我们2022年的文章,有补充说明。阁下,如果有心改善准确性,请思考以上论述。我们可以深入讨论。(加入一个不准确页面的讨论,有一定向风险。)--Bwshen留言2023年2月25日 (六) 05:38 (UTC)[回复]
关于图片,较难改动,可能需要制作一张新的(中文)图片,或者从c:Category:Chaos theory尝试从已有图片中,找出合适的图片替换。阁下可能误会了在下请教的问题,在下没有质疑劳伦兹2008年的看法,在下质疑的是该文没有直接支持“轨迹在有限范围内的特性,可由蝴蝶有限的双翼所显示”。假若阁下的意思是Lorenz 2008的看法,虽然没有直接写明,仍包含“轨迹在有限范围内的特性,可由蝴蝶有限的双翼所显示”一点,则正正属于需要引用其他来源作出此诠释的情况,而非引用Lorenz 2008。假若阁下认为有直接写明,请给出页码和引文。维基百科的引用是要方便查证,倘引用较不直接相关的内容,无助于读者查证,若纯属acknowledgement and attribution用途,前句已引述Lorenz 2008。——留言2023年2月25日 (六) 11:44 (UTC)[回复]
(1) I am working on it; (2) are you aware of the butterfly pattern solution (e.g., the first Figure of Butterfly Effect in English)? it is obvious that the butterfly wings are finite. I will keep you posted soon. -Bowen--Bwshen留言2023年2月25日 (六) 12:05 (UTC)[回复]
I'm not saying the wings are not finite. (I thought this is the third time I'm reiterating this.) I'm saying Lorenz 2008 never mentions this, so can't be used to support that statement.--留言2023年2月25日 (六) 12:10 (UTC)[回复]
To be clear, I fully agree that in File:Lorenz_attractor_yb.svg the wings are finite and this suggests the trajectory is bounded. I never say this statement is wrong. But whether the editor agrees or not means nothing on Wikipedia. We should cite suitable sources that directly supports the statement. Shen 2019 does check out this statement, while Lorenz 2008 doesn't seem to, so we should cite the former (and maybe other sources) but not the latter. Of course if Lorenz 2008 directly supports the statement we can cite it as well.——留言2023年2月25日 (六) 12:30 (UTC)[回复]

No, it seems that you have misunderstand the statement here, maybe you are an authority in this area, but here, the authority refers to the authority of the publisher. For example, if Alice published an article on one journal and Bob wants to cite it on Wikipedia, then the authority means the authority of Alice, not Bob. If you are telling me your real identity, a similar case happened on English Wikipedia about ten years ago when Dr. Timothy Messer-Kruse tried to fix some errors in the article "Haymarket affair". He used a similar strategy by announcing he is an expert, but some editors refused him, which later caused criticism towards Wikipedia.--ときさき くるみ 2023年2月25日 (六) 06:12 (UTC)[回复]
I understand your concern. That's why I asked the following.

I fully agree, so it is usually not needed. I think Tokisaki Kurumi's comment is just in case we'd still like to cite Lorenz 2008 for that statement, since (as I've said) searching for "bounded" and "finite" etc yields no result in Lorenz 2008 and in this case, the editor adding it should give the page number or quote to help locating the relevant content.——留言2023年2月25日 (六) 12:39 (UTC)[回复]

I added the following from Lorenz (2008):
--
A related property of chaos is absence of true periodicity. For many systems, because the number of possible states, each differing more than a given amount from any of the others, is limited, we can be sure that if we wait long enough we shall encounter a state close to one that we have seen before, and we may think of the later state as the earlier one plus a small perturbation.
--
"recurrence" also indicates "boundedness". I appreciate your comments and suggestions which helped clarify for many readers.
Thanks,
-Bowen--Bwshen留言2023年2月25日 (六) 13:17 (UTC)[回复]
BTW, the first figure was added by Eliot in early 2008. (Unfortunately, the last edit by Eliot was done in 2016.) I already sent Eliot the following message:

Hi Eliot,

As mentioned, a quick fix is to replace "attractor" by "trajectory".
