User talk:AnInformedDude

A belated welcome!
Here's wishing you a belated welcome to Wikipedia, AnInformedDude. I see that you've already been around a while and wanted to thank you for your contributions. Though you seem to have been successful in finding your way around, you may benefit from following some of the links below, which help editors get the most out of Wikipedia:
 * Introduction
 * The five pillars of Wikipedia
 * How to edit a page
 * Help pages
 * How to write a great article
 * Editor's index to Wikipedia

Also, when you post on talk pages you should sign your name using four tildes ( ~ ); that should automatically produce your username and the date after your post.

I hope you enjoy editing here and being a Wikipedian! If you have any questions, feel free to leave me a message on, consult Questions, or place helpme on your talk page and ask your question there.

Again, welcome! Sam Sailor Sing 03:08, 15 November 2013 (UTC)

Tonometry calculations
As each method is different, the calculations required will depend on the mechanism. There are some studies which compare methods to the gold standard which is an intracameral (in the eye) pressure transducer. These studes are normally performed during cataract surgery when you're already inserting instuments in to the eye. I'm pretty sure there is an ISO standard but don't know the number. For Goldmann tonometry (the clinical gold standard), you would need to consult the original paper from the 1950s. Briefly, Goldmann contented that when an area of 3.05mm was flattened, then the meniscal forces of the tear film were equivalent to those of corneal rigidity (cancelling each other out) so that the pressure could be inferred by the force applied from a calibrated adjustable tension spring. Current Goldmann tonometers all have a calibration bar that can be used to check the forces they apply. Hope thats helpful.Nernst (talk) 21:42, 8 December 2012 (UTC)

November 2013
Hello, and thank you for your contributions to Wikipedia. I noticed that you recently added commentary to an article, Iron(II) phosphate. While Wikipedia welcomes editors' opinions on an article and how it could be changed, these comments are more appropriate for the article's accompanying talk page. If you post your comments there, other editors working on the same article will notice and respond to them, and your comments will not disrupt the flow of the article. However, keep in mind that even on the talk page of an article, you should limit your discussion to improving the article. Article talk pages are not the place to discuss opinions of the subject of articles, nor are such pages a forum. Thank you. This diff Sam Sailor Sing 03:09, 15 November 2013 (UTC)

Response to Sam Sailor from AnInformedDude
Hi there, thanks for your message. I was merely pointing out that Iron (II) phosphate and Iron (III) phosphate ought to have different colours due to the differing oxidation states of the Iron atoms that comprise their molecules. I did not, however, mention either the correct colours for the relevant chemical compounds, nor a specific source which vindicates the colours of these two compounds under "standard conditions". Of course, someone with chemistry knowledge ought to be able to point out what the colours are. Further comments about the appearance of the crystal or other granular structures of the compound would be a good idea. I may bring this to your attention on your page.

 * Hello Dude. Mentioning my name with the user prefix echoes. Why not raise the question on Talk:Iron(II) phosphate? And/or on Wikipedia talk:WikiProject Chemistry? Best, Sam Sailor Sing 07:12, 20 November 2013 (UTC)
