This is the user page for Michael (Mike) D. Turnbull, created on 26 April 2018. My username is my real-life name but I am not in any way connected to the notable individuals with similar names listed atMichael Turnbull.
My first contribution was a major re-write and expansion of the biography ofRalph Raphael, followed by additions on other pages to cross-reference him. I have done the same forAlan Battersby. I work to improve articles onICI; pesticides invented atJealott's Hill, for example2,4-D,MCPA,diquat,cyhalothrin,paclobutrazol,tefluthrin,fluazifop andazoxystrobin; plus others inSyngenta's product range such asbutafenacil,mesotrione,pydiflumetofen andacibenzolar. I also write about biosynthetic routes, for examplevitamin B12 andchlorophyll, adding oddments related to chemistry in general.
Chemistry is the study of the behaviour of the chemical elements and there is a simple template here which gives their names on hover-over and allows readers to jump to the relevant pages in the encyclopaedia by clicking on the cell of interest. My professional focus isorganic chemistry and during my career I have made many novel compounds containing the marked elements.
I prefer to edit existing articles rather than create new ones. At present there are 7,138,880 articles on the English WIkipedia and my opinion is that this is too many. For every new article it might be best to delete a less worthwhile one, so new editors should consider usingWP:AfD beforeWP:AfC.
In October 2020 I assistedEd Gold by uploading some ofhis remarkable photos to Wikimedia Commons with {{CC BY-SA 4.0}} licenses, which means not only that they can be incorporated in articles here but also that they may be freely downloaded for any purpose whatever, provided that Ed Gold and/or Wikipedia is acknowledged if they are subsequently published. Note, however that many are portraits of living people and these persons are protected by {{Personality rights}}, which means that they must be contacted before the image can be used for a commercial venture. This is not a hurdle for re-use within Wikipedia articles or for personal non-commercial use.

/64 to the end of the URL. For exampleSpecial:Contributions/2601:5C0:C380:4980:BD25:9843:27D3:B53C/64The source editor has an "advanced" menu bar with a search-and-replace function (icon on right). This is very powerful but must be used with care! An interesting example is to use aRegEx search to convert external links incorrectly placed in the body text into proper citations:
1) Search for expression=\[https?(.*?)\] (this matches both http and https prefixes)
2) Replace with<ref>https$1</ref> (tick box "Treat search string as a regular expression")
3) Preview to check whether any legitimate external links have been converted to refs and manually put them back. Save/publish changes.
Finally, use theWP:ReFill toolat this link to convert the bare URLs into{{cite web}} templates.
SeeWT:WikiProject Film/Archive 79#Masking imdb links as wikilinks for the background.These searches should give no hits but usually will have some that can usefully be cleaned up.
This insource search should have no hits and if it does the edit that introduced them should be reverted.
