== Guidelines for style and organization ==

Some of the style guidelines are obvious and well known to most. But hey it's nice to be thorough.

* None of the guidelines below should contradict '''[[wikipedia]]''' style and organization guidelines. 

* All '''entries''' should be list items. 

* The timeline is to be '''sectioned''' by century. Century section headings should give the century's number in roman numerals. 

* approximate year '''dates''' should be preceded by ca. (abbreviation for circa). 

* '''Dates''' are given using the gregorian calendar. Hijra calendar dates should be identified with AH.

* I figure the separator between the date and the content of a timeline '''entry''' should be a sequence of one or more keywords ordered alphabetically and enclosed in square brackets, naming the research field for which the entry is most relevant; eg, [mathematics], [ceramics; materials; metallurgy] and so on.

* '''References''': Instead of an external links section, a "References" section is used with external links given in it as needed. The references are numbered so they can be used for citations in the body of the text.

* '''Entries''' that are bloated due to biographical detail should instead link to the subject's own article, and create it if it does not already exist.

* '''Keywords''' or at least some of them should be bold for faster browsing. 

* There may need to be a reworking of the article's '''title''', and thus its placement in any larger structure of articles.

==Resource?==
I found a resource, but is it good? It is well referenced:

Khaleel, Kasem (2000). The Arabian connection: A conspiracy against humanity. Lincolnshire, IL: Knowledge House Publishers. ISBN: 0-911119-70-1.

A neighbor recommended it, and it is available on Amazon. While it does not appear to be biased, it does have a somewhat personal tone, however thoroughly referenced.

He asks the question: "Who originated the modern sciences?" The book purports to answer this question.

Cover bio: "Dr. Kasem Khaleel is a medical writer specializing in health and the history of science. The author of over twelve books, his ten year study in the field of scientific history culminated in the publication of this book."

== first manned rockets ==

"1600s [flight; rocketry] Turkish scientist Hezarfen Ahmet Celebi took off from Galata tower and flew over the Bosphorus. Lagari Hasan Çelebi, another member of the Celebi family, sent the first manned rocket, using 150 okka (about 300 pounds) of gunpowder as the firing fuel. This is more than two hundred years before similar attempts in Modern Europe and the United States."

were there not chinese experiments in manned rocketry hundreds of years before this?

ah, it turns out that i was thinking about the legend of Wan Hu, which takes place in the 16th century.

==first war rockets==

Sultan of Misore coud not be an inventor of war rockets. For example: http://en.wikipedia.org/wiki/Kazimierz_Siemienowicz

== Text on amicable numbers misses Descartes contribution to same pair. ==

The text, "1600s [mathematics] The Arabic mathematician Mohammed Baqir Yazdi gave the pair of amicable numbers 9,363,584 and 9,437,056 still many years before Euler's contribution [1]." was copied from http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/Arabic_mathematics.html and the way it reads misses that according to http://amicable.adsl.dk/aliquot/c2/c2_7.txt (this link was taken from the Wikipedia page [[Amicable_number]] and as can be seen from http://amicable.homepage.dk/apstat.htm#discoverer ) that single pair is '''joint discovered''' by Decartes i.e. it is recorded as Yazdi/Decartes. Euler obviously came later (well he was born later, duh!) and has 59 pairs to his name. Also interestingly that original copied reference, http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/Arabic_mathematics.html also mentions the pair 
17296 and 18416 and also says how these had been mistakenly attributed to Euler, "He also gave the pair of amicable numbers 17296, 18416 which have been attributed to Euler, but we know that these were known earlier than al-Farisi, perhaps even by Thabit ibn Qurra himself." Other sites attribute this to Fermat and not Euler, and would show this as being found by all of al-Banna, Farisi and Fermat. That site linked on the Wikipedia page as reference [1] for the Arabic mathematics at the University of St-Andrews Scotland really has a thing with Euler and that raises issues with its accuracy. I have no idea how to change this other than to say that Yazdi was co-discoverer of that pair with Descartes (1636)...but that doesn't really spin it right now does it ?

== Text on ibn al-Haitham implies he knew proof 750 years before Lagrange. This is wrong. ==

The last paragraph in the section for 965 - 1040 ...has the last sentence as "... Lagrange gave the first known proof in 1771, ... more than 750 years after al-Haytham."
There is no evidence that "al-Haytham" found a proof. He just stated the theorem. It even says so in the reference. The "750" year value was copied from http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/Arabic_mathematics.html and reworded. This is very much [[WP:OR]]. Please get it right - with these mistakes you make a mockery of both the contributions of ibn al-Haitham and Lagrange to mathematics. [[User:Ttiotsw|Ttiotsw]] 23:28, 22 October 2006 (UTC)

== Does this topic conform to NPOV? ==

Im athiest, so i dont care either way, but shouldn't there also be Christian, Hindu, Buddhist and Jewish Science as well?

Also, is not science and technology a seperate subject (not neccisarily mutually exclusive) to a religion.

This article would do much better to be "Timeline of Human Science and Technology" or at least "Timeline of Middle-east Science and Technology" <small>—The preceding [[Wikipedia:Sign your posts on talk pages|unsigned]] comment was added by [[Special:Contributions/220.233.221.252|220.233.221.252]] ([[User talk:220.233.221.252|talk]]) 13:10, 27 January 2007 (UTC).</small><!-- HagermanBot Auto-Unsigned -->

Not really...this article doesn't pertain to Islam's contributions to science but rather to the contributions to science made by the civilization known by historians as the Islamic civilization. Therefore it doesn't imply that science is mutually exclusive to a religion but highlights the contributions to science made by Islamic civilization. I do however think that a more appropriate title would be "Timeline of Science and Technology in Islamic Civilization".  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/70.81.17.219|70.81.17.219]] ([[User talk:70.81.17.219|talk]]) 11:22, 14 May 2010 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

==Suggestion to change title into "Timeline of science and technology in the Islamic world"==

Although a lot of the science described hier is very important, I have my doubts that this is all "Islamic science".

The reasons for my doubts are:
Today there is no pure "Islamic science" under the term of what we understand as "physical [[Science]]". Science is science, that's it. So science in the Islamic world is just science, not Islamic science. Under the official term "science" there isn't also no Christain science, Jewish science, or whatever.

But, under certain cirumstances we can name it indeed Islamic science:

*[[Political geography|Political geographically]] based argument: During the Islamic empire, when it was a [[political division]] of a geographical entity, a [[sovereign territory]]. In this case there is an argument to name it "Islamic science". For example it is normal talk about Belgium science (Science performed by a person from Belgium), Maroccan science (science performed bu a person from Marocco). But concerning todays, it is strange to talk about Islamic science, since this [[Linguistics|linguistically]] implies science performed by a [[Islamist]] or a [[Moslim]], hereby linking the religion of that person with the science he is doing. As I told earlier, in this point of view it is also strange to talk about "Jewish science" (however, Israelian science is correct). Unlike Europe (the continent), the Islam is not a a geographical entity, and unlike the [[European Union]] the Islamic world is not a Political geographically union also. Althought the last one is a weak argument. At the wikipedia you will not find any sites about "European sciences", only maybe something like "Science in (the) Europe (Union)". Also you will not find a site "Western science". But to name it Islamic science according during the Islamic Empire is, I think, correct. According to todays, "Islamic world science" is also okay, although a little strange and murky to me, since we do not also speak about "Sciences in Catholic countries in the world".

*[[Culture|Cultural]] [[entity]] based argument: Science developed purely based on the merit of a Islamic culture. Some argue that this is the case indeed with science in the Islamic world during the period of [[Islamic civilization]]. I personally disagree with this argument, because science is not developed purely on the merit of that culture, without outside knowledge or influences. For example, science during that period was based and influenced by the sciences from Europe and vice versa. Only under very very special circumstances this argument is valid, for example science in the Empire of China during the their period of isolation (although the political geographically based argument is already valid according to China). Or maybe science or technology in South Amerika before there was contact with the Europeans.

*[[Ethnic]] based argument: Science or technology developed by an ethnic group or race. For example the arrow developed by an [[American Indian]]. Although this argument is a dubious and a maybe racist one, for example "white science".

*[[Religion]] based argument: In some circumstances we can speak of religious science, when we speak of science according to the interpretation of the holy book of that religion. See for example [[Christian Science]].

Conclusion: according to the arguments, and the fact that this site described sciences upto the 20th century, it does not meet the above criteria.

So, I think that the topic name of this page should be changed from "Timeline of Islamic science and technology" to "Timeline of science and technology in the Islamic world". But I'm not going to change the title for the upcoming two days, first I want to know from someone about why and how of the present title [[User:Demophon|Demophon]] 14:21, 27 June 2007 (UTC)

::I have changed the title. [[User:Demophon|Demophon]] 18:09, 30 June 2007 (UTC)

==Split into two articles?==
I think it would be a good idea to split this article into two seperate articles, to reduce the size of the article and to make space for more additions. One article can deal with the timeline of [[Islamic science]], and the other with the timeline of [[Inventions in the Muslim world|Muslim technology]]. Any comments? [[User:Jagged 85|Jagged 85]] 00:24, 28 August 2007 (UTC)

==Title and citations==
Great article, but does the title ("Timeline of science and technology in the Islamic world") reflect the content? Many of the later entries refer to Muslim scientists who were active (and often born) outside the Islamic world: for example, Pierre Omidyar and Jawed Karim were both born in the West, while Ahmed Zewail, Fazlur Khan, Abdus Salam, etc were all active there.

Also, are we certain that all the entries are Muslim? For example, Jawed Karim's mother was a German woman called Christine, while Lotfi Zadeh is listed online as having a Jewish Russian mother. The problem is that most scientists don't write about their religious views (Abdus Salam being a notable exception). Without sources, even Pierre Omidyar could potentially be a Christian or Zorastrian. [[User:Udzu|Udzu]] ([[User talk:Udzu|talk]]) 15:31, 5 March 2008 (UTC)

: No response, so I've renamed the article "Timeline of Muslim scientists and engineers", and added a ''refimprovesect'' for the 20th and 21st century scientists. [[User:Udzu|Udzu]] ([[User talk:Udzu|talk]]) 10:17, 9 March 2008 (UTC)

:Unless there is a clear ref that states they are Muslim then a number of the 20th/21st century can be removed. I'll individual flag each one. If they stay unref'd then we eventually delete the entry. [[User:Ttiotsw|Ttiotsw]] ([[User talk:Ttiotsw|talk]]) 06:49, 19 March 2008 (UTC)

==Change the article title==
In June 2007 Demophon made a reasoned argument for a change of title for this article.  Then in March 2008 Udzu changed it back again , but I'm not sure I folow his reasons for this. Can we have a debate?

I suggest "Timeline of science and technology in the Islamic world" is the better title. We dont talk about Christian science or Atheistic science so why have an Islamic science. As User:Udzu says , little is known of the beliefs of the scientists mentioned here. The Islamic world is a cultural entity under which science operated for centuries. I propose changing it back again to "Timeline of science and technology in the Islamic world"  . [[User:Lumos3|Lumos3]] ([[User talk:Lumos3|talk]]) 11:29, 7 August 2008 (UTC)

:I whole heartedly disagree. Jews consider themselves to be a race, however there are black Jews. So why should Jews be classified as a race? It is Islamic science, there are many fieleds, (see [[Aviccena]] for details). In addition as noted in the introduction many Muslims say the Qu'ran expresses scientific knowledge. ANd that is why "Islamic Science" is Islamic Science. Do you understand? I hope I have clarified enough info. Leave the title as it is. [[User:LOTRrules|<span style="color:blue;">'''Lord of Moria'''</span>]] <sub>[[User talk:LOTRrules|'''<span style="color:purple;">Talk</span>''']]</sub> <sup>[[Special:Contributions/LOTRrules|'''<span style="color:gold;">Contribs</span>''']]</sup> 15:34, 7 August 2008 (UTC)

I propose that the article be split into two parts: '''Timeline of classical Islamic science and engineering''' and '''Timeline of modern Muslim scientists and engineers'''. The reason why I think this would be more appropriate is because the classical period deals almost exclusively with the Islamic world, whereas the modern period deals with Muslim scientists and engineers from both within and outside the Islamic world. Furthermore, it would help reduce the length of the article, without having to sacrifice any content. Regards, [[User:Jagged 85|Jagged 85]] ([[User talk:Jagged 85|talk]]) 03:16, 9 August 2008 (UTC)

== Taqi al-Din ==

from the source cited; "To compensate this relative "failure", Taqī al-Dīn evokes in his book Kitāb Nūr an important discovery that was never mentioned before. This regards an instrument that makes the objects located far away appear closer to the observer. He says: "I made a crystal (billawr) that has two lenses displaying in details the objects from long distances. When they look from one of its edges, people can see the sail of the ship in far. My instrument is similar to that of ancient Greeks which had made and placed on the Tower of Alexandria" [13].

Taqī al-Dīn's assertion evokes no less than a kind of spectacles, the instrument that had beginning from 1609 the tremendous fortune we know of, when Galileo directed it to the skies and used it as a telescope. As he describes it, Taqi al-Din's instrument helps to see the objects in detail by bringing them very close. In addition, he stated that he wrote an article explaining the way of making and using this instrument. Yet, there is confusion concerning a part of his explanation, when he claims that his apparatus has similar properties to one used by ancient Greeks in Alexandria penthouse. Obviously, this derives from the tales and narrations that surrounded this mysterious monument, like burning mirrors.

At any rate, this is a topic that needs to be investigated carefully, to state whether such an invention was really made in Ottoman lands, if Taqi al-Din's instrument attracted the attention of his contemporaries, and most of all, if it was transmitted in a way or another to Western Europe by the end of the 16th century. According to the known and available information, spectacles were used in Europe at the beginning of the 17th century. It was in this context that Galileo used them in astronomical investigation from the summer of 1609. Now, Taqī al-Dīn's book had been written nearly 30-35 years before. What conclusions could be drawn from these dates? Only a thorough research in the original archives can attain a conclusion. What we can state for the moment is that this is an area of research worth a deep investigation, and that it may reveal some hidden secrets."

* ''1551 - 1574 [astronomy, engineering] [[Taqi al-Din]] invents a rudimentary [[telescope]], as described in his ''Book of the Light of the Pupil of Vision and the Light of the Truth of the Sights'' around 1574. He describes it as an instrument that makes objects located far away appear closer to the observer, and states that the instrument helps to see distant objects in detail by bringing them very close. He also states that he wrote another earlier treatise explaining the way this instrument is made and used, suggesting that he invented it some time before 1574. <small>This ref was causing a formatting error, so I took it out of the rendered page.

::I assume the [[User:J8079s|J8079s]]'s addition of a reference was to support the reinstating of the above paragraph about [[Taqi al-Din]] (please include rationals in summery statements in future). I have moved the above paragraph to talk because it is an '''incorrect to statement of fact''' to say "''Taqi al-Din invents a rudimentary [[telescope]]''" in 1551 - 1574.  The source Dr. Hüseyin Gazi Topdemir himself states "''this is a topic that needs to be investigated carefully, to state whether such an invention was really made in Ottoman lands''" and that "''there is confusion concerning a part of (Taqi al-Din's) explanation''".

== 20th/21st century entries ==

I'm concerned about the validity of sources for the recent entries on this list, specifically the ones covering 1900 to the present day. It seems that a large number of those entries are either unsourced or use only self-published sources. Additionally, in our current globalised world it doesn't seem to make sense to talk about Islamic, or Western, or Chinese, or any other kind of science and engineering. Big projects are invariably multiresearcher - what percentage of coinventors have to be Muslim before it can be considered Islamic science? How do we define "Muslim scientist"? Born in a majority Muslim area? To a Muslim family? Converted to the faith? Before or after the invention? It seems like a perennial thorn and just not possible to reconcile with Wikipedia's original research and neutral point of view policies.

Please note that I'm '''not''' talking about the entries before 1900 (or even, arguably, before 1945). Before then, science and engineering were separate and nationalistic/cultural. But I think that this article would stand better as a historically focused one rather than going through to the present day. [[User:Orpheus|Orpheus]] ([[User talk:Orpheus|talk]]) 05:16, 29 January 2009 (UTC)

: Incidentally, "First Muslim to do X" is kind of circular logic - I took out a couple of those as well.

== Rewrite ==

The more I look at this article, the more I think it needs a complete rewrite. I'm going to have a bash at it, and I'd appreciate any suggestions or criticisms that the community has. I'll list my objectives here, and I welcome any additions or modifications. These are off the top of my head - I'll probably end up making lots of modifications myself...

* ''Avoid a chronologically ordered duplication of [[Inventions of the Islamic Golden Age]]''. I think that's a pretty good article, and I can see there's a lot of overlap between there and here. I envisage lots of links into subsections of Inventions of the Islamic Golden Age, in lieu of detailed descriptions here.
* ''Condense multiple discoveries into single entries''. For instance, Gerber has a lot of independent entries here, one after the other. I propose condensing those into something like "[[Gerber]] was active in advancing the science of chemistry from X to Y CE. His discoveries included ''short list of primary discoveries, especially those relevant to subsequent timeline entries''."
* ''Apply a narrower definition of science and engineering''. The legal, political and culinary innovations are good fodder <small>sorry...</small> for timelines of jurisprudence, governance and, um, gourmance, but they don't belong here. 
* ''Better style''. I like the idea of categorising discoveries, especially as this is a timeline and not a categorised list, but there must be a better way to do it. Any suggestions?
* ''Summarise, and include less detail on invention specifics''. Here's a good timeline entry and one better suited to a brief summary and a link to [[Inventions of the Islamic Golden Age]]. See if you can guess which is which.
** 1579 [civil engineering] The first prefabricated homes and movable structure are invented by Akbar the Great.[307]
** 1589 - 1590 [astronomy, engineering, metallurgy] The seamless celestial globe invented by Muslim metallurgists and instrument-makers in Mughal India, specifically Lahore and Kashmir, is considered to be one of the most remarkable feats in metallurgy and engineering. All globes before and after this were seamed, and in the 20th century, it was believed by metallurgists to be technically impossible to create a metal globe without any seams. It was in the 1980s, however, that Emilie Savage-Smith discovered several celestial globes without any seams in Lahore and Kashmir. The earliest was invented in Kashmir by the Muslim metallurgist Ali Kashmiri ibn Luqman in 998 AH (1589-1590 CE) during Akbar the Great's reign; he invented the method of lost-wax casting in order to produce these globes. 21 such globes were produced, and these remain the only examples of seamless metal globes. These seamless celestial globes are considered to be an unsurpassed feat in metallurgy, hence some consider this achievement to be comparable to that of the Great Pyramid of Giza which was considered an unsurpassed feat in architecture until the 19th century.[310]
* ''Less pride, more NPOV''. This isn't a big problem when looking at the tone, but the quality of some of the entries suggests a completely understandable but sadly unencyclopedic enthusiasm to claim a discovery for "our" side. For reasoning, see my [[User:Orpheus/Science and nationalism|own feelings]] on the matter (warning: may include harmful quantities of undirected musing). 

As I said above, suggestions welcome here or on my talk page (probably a better venue for discussing the last entry) and I'll endeavour to create a list of (or perhaps archive on a talk subpage) the content I end up removing during the rewrite.

In response to Kitty's message, while I appreciate the formatting changes you've made to the article, I had a problem with the large amount of sourced content you were removing, and it seems some of it was even by accident? I thought it would be best to just restore all the sourced content and then start again, section by section. I'll be more than willing to help shorten each entry into a more concise summary format.

:While almost all of it was sourced, A LOT of it was repetitive. A lot of it was offtopic. And all of it was too poorly constructed so as to be helpful, a timeline should be concise, a timeline shouldn't have these ranges of 300,400,500 years referring to no real event. There were a dozen things that got placed in two or three or four times. The giant blocks of text seemed inappropriate for this article, and it was obvious that having these large, poorly worded, and often contributed to multiple additions and a difficultly in comprehending the text. I understand [[WP:PRESERVE]] but it seemed that the format, the bulk of irrelevant, inaccurate and unreadable text was hampering contribution. I believe the right approach is to cut out the cruft and try to accept more appropriate edits in the style of some of the respectable timelines such as chemistry. I apologize for the cursing but I spent hours trying to clean out these awful entries and was taken aback to see a lot of it come back in. The page took hours to read, comprehend and try to summarize succinctly (again, I think we should try to keep the events on this page significant, at least having citations inside WP, lest we be overrun); again, looking at featured timelines such as [[Timeline of chemistry]] for an example. --[[User:KittyKAY4|kittyKAY4]] ([[User talk:KittyKAY4|talk]]) 03:27, 7 June 2009 (UTC)
: Again, even when sourced and succinct we need to look at these contributions... 1000-1048 Abū Rayhān al-Bīrūnī criticizes the theory of the transmutation of metals.[99] followed by 1000-1037 Avicenna criticizes the theory of the transmutation of metals.[95] and then 1377...discredits the theory of the transmutation of metals.[239]. In my mind... unless the alchemy leads to the creation of a chemistry technique such as [[crystallization]], we should avoid such pointless, repetitive commentary all over this article... --[[User:KittyKAY4|kittyKAY4]] ([[User talk:KittyKAY4|talk]]) 03:32, 7 June 2009 (UTC)

{{anchor|Disputed}}
== Article issues (X-2009) ==
* '''Incorrect entries; misreading of sources''': There are a number of problematic statements, in various sections, e.g.:<br /><br />(1) "Geber...introduced...chemical processes such as ... filtration": incorrect, filtration goes back at least to the Hellenistic alchemists (''A short history of chemistry'', Partington, 3rd ed., Courier Dover, 1989, {{ISBN|0486659771}}, p. 23.)<br />(2) "An early industrial factory complex for Islamic pottery and glass production is built in Ar-Raqqah, Syria...nearly three hundred new chemical recipes for glass are produced at all three sites."  This is a misreading of the source ({{doi|10.1111/j.1475-4754.2004.00167.x}}.)  What there are nearly three hundred of is samples of glass, which were analyzed by electron microprobe.  Different samples may have been produced by the same recipe and the authors group the samples into just a few main types.<br />(3) "c. 930: The cartographic grid is invented in Baghdad": The cartographic grid itself was not invented in the Islamic world as it dates back to the Hellenistic period and was used e.g. by Ptolemy (''Science and civilisation in China'', Joseph Needham, vol. 3, Cambridge University Press, 1959, {{ISBN|0521058015}}, p. 527.)  The source ([http://findarticles.com/p/articles/mi_m0QYQ/is_1_2/ai_n6160527/], David A. King, "Reflections on some new studies on applied science in Islamic societies (8th-19th centuries)", ''Islam & Science'', June 2004) discusses some maps made with a special, Mecca-centered, type of cartographical grid for the purpose of determining the ''qibla''; in his book (''World-maps for finding the direction and distance to Mecca: innovation and tradition in Islamic science'', David A. King, Brill, 1999, {{ISBN|9004113673}}) King discusses these maps in greater detail.<br />(4) "Muhammad ibn Mūsā al-Khwārizmī invents the quadrant":   The quadrant itself was not invented in the Islamic world as it was described by Ptolemy in the ''Almagest'' (book I, chapter 12, pp. 62 ff. in the translation of Toomer, {{ISBN|0715615882}}.)  King credits al-Khwarizmi with describing the sine quadrant, a particular type of quadrant (''Astronomy before the Telescope'', Christopher Walker, ed., {{ISBN|0-312-15407-0}}, p. 167.)  King also considers it possible that the author of an anonymous treatise on the universal horary quadrant, or ''quadrans vetus'' (another type of quadrant) is al-Khwarizmi, but points out that the author does not claim to have invented it ({{bibcode|2002JHA....33..237K}}).<br /><br />This is just from a quick scan, which also reveals many more problems.
* '''Scope confusion''': The article describes the framed-tube system of skyscraper construction and other structural innovations developed by Fazlur Khan, and the erection of the John Hancock Center, the Sears Tower, and a few other American skyscrapers.  These are not inventions of the Islamic world as they occurred in the United States, which is not part of the Islamic world. (Khan moved to the U.S. in the 1950s and later worked for SOM in Chicago, which is where he did his designing; see ''Engineering legends: great American civil engineers : 32 profiles of inspiration and achievement'', Richard Weingardt, ASCE Publications, 2005, {{ISBN|0784408017}}, pp. 75 ff.)
* '''No criterion for novelty or significance of entries''': Any timeline or list needs some criterion for deciding what is important enough to include as otherwise it will become clogged with cruft.

== Unreliable source - Muslimheritage.com material ==


Content from Muslimheritage.com / FSTC is an unreliable source, as discussed on Wikipedia:Reliable_sources/Noticeboard/Archive_18#History_of_Science. None of its publications are peer-reviewed, and its authors often exhibit a strong bias and incomplete or flawed citation practices. The site has been used as a source in numerous science and history of science articles to make extraordinary claims about Islamic invention and discovery. I am working to remove these extraordinary claims where they stem directly and solely from a Muslimheritage.com reference. Many of these claims were added by a user who has a history of using flawed sources for extraordinary claims, as discussed on Wikipedia:Requests_for_comment/Jagged_85. That page details numerous examples where claims from these sources contradict more reliable sources, on a scale which casts the entirety of the material originating from the site into doubt.

::: I think this revert is brutal to say the least, and work should be done to re-add deleted information. I also think that a cutoff at 1800 on the basis that science became "global" then is vacuous because simultaneously it can be argued: that science and "knowledge" has always been global through well-known and unknown paths of transmission , and that "islamic" or arab scientists remained relatively isolated from Europe in the 18th and 19th centuries.

I realise that this runs counter to [[WP:AGF]] but that policy is not a suicide pact and the problems caused by the sock are both deeply engrained and common. Please can someone check the source and provide a relevant quotation from it. Thanks. - [[User:Sitush|Sitush]] ([[User talk:Sitush|talk]]) 02:24, 17 October 2013 (UTC)

==Oh my...==
I've just done a load of clean up. And yet I found that so much of this is a copyvio of http://www.cyberistan.org/islamic/

Probably I could get the offending stuff out.  But the history - the attribution... the humanity!

* http://metaexistence.org/timeline1.htm appears to be a copyvio of the Wikpedia page, you can see the page being built and there is a [1] in the copy, but no footnotes.  Many other pages have similar clues. I am not sure to what extent the other sources are  copyvio'd here though. And they don't look like RS either.

::All the copyvio from given online sources is gone, I hope. We are left with a few issues:
::# We need RS for the material already here  Some of the books listed above are good candidates.
::# A lot needs to be added. Remember this is timeline, not a "we did it first" list, so tech arrivals from India, China, Eurpoe etc. are just as important.
::# Someone should look at the Gerber stuf and make sure its no pseudo-Gerber.
::# Everything should be evaluated as to whether it belongs here.

:::5. Some of the cruft has seeped into [[Timeline of mathematics]] and [[Timeline of numerals and arithmetic]]. All the best, ''[[User:Rich Farmbrough|Rich]]&nbsp;[[User talk:Rich Farmbrough|Farmbrough]]'', <small>09:52, 7 April 2014 (UTC).</small><br />
::::Are you familiar with [[WP:Jagged 85 cleanup]]? In brief, an amazing amount of boosterism was performed by an editor who managed to inject an enormous amount of UNDUE material based on unreliable sources, or often with simply made-up references. I do not know the status of this article, and am mentioning the issue merely as a possibility to bear in mind. Searching for "muslimheritage" above shows the view established when the Jagged case was unfolding that any references based on that website need to go.

:::::Yes, thanks for bringing it up though. There is always boosterism on discoveries and inventions pages - though I know Jagged was an extreme example.  I am going to leave this one alone for a bit I think.  All the best, ''[[User:Rich Farmbrough|Rich]]&nbsp;[[User talk:Rich Farmbrough|Farmbrough]]'', <small>21:55, 7 April 2014 (UTC).</small><br />

==this is missing a lot==
Avicenna, Al-Haytham (alhazen) for example. Al-tusi, al-nafisi, al-razi (rhazes), it's a list shockingly lacking in the biggest names. [[Special:Contributions/135.23.132.58|135.23.132.58]] ([[User talk:135.23.132.58|talk]]) 07:21, 15 November 2016 (UTC)
