Who is the father of trigonometry?

How many total trigonometric identities? Highlighter singh (talk) 15:41, 25 February 2016 (UTC)

Hello fellow Wikipedians,

I have just added archive links to {{plural:1|one external link|1 external links}} on Optics. Please take a moment to review [https://en.wikipedia.org/w/index.php?diff=prev&oldid=712861944 my edit]. You may add {{tlx|cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{tlx|nobots|deny{{=}}InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

• Attempted to fix sourcing for http://dbhs.wvusd.k12.ca.us/webdocs/Chem-History/Bohr/Bohr-1913a.html

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{tlx|Sourcecheck}}).

{{sourcecheck|checked=true}}

"Bacon was able to use parts of glass spheres as magnifying glasses to demonstrate that light reflects from objects rather than being released from them."

:This claim is made also in History of Optics; both articles would benefit from a citation which I have as yet been unable to discover. Any historians or physicists who can help out?TimeForLunch (talk) 15:02, 23 December 2016 (UTC)

There is absolutely nothing in this article about optical units. In fact when searching, "unit" is found in "community" and little else. An article about optics need to say something about these: lumen; candela, foot-candle, ... 47.215.188.197 (talk) 03:11, 8 February 2017 (UTC)

Editors of this article may be interested in the discussion at Talk:Silicon photonics#Fiber Optics & Silicon photonics. User:Ne0Freedom is trying to remove :Category:Fiber optics from :Category:Optics and instead put it in his newly created category, :Category:Silicon photonics. I strongly oppose this. His view seems to be based on the misconception that anything optical with silicon in it (even silicon dioxide—glass) is automatically "silicon photonics".--Srleffler (talk) 01:52, 22 March 2017 (UTC)
