thread_title:  Araucarites kozloduyana 

message: The statement "At least one genus, possibly Agathis, survived into the Eocene.[1]" - makes no sense.  Right below this is a section that names three (3) extant "genera" of the Araucariaceae.  So what does this opening statement mean?  Of course at least one genus survived.  That's what the article is about.  The timeline is also wrong, where it says "recent".   It should be "Present".  98.194.39.86 (talk) 04:06, 5 December 2016 (UTC)
replies: text: Per source, it is talking about araucarians in the northern hemisphere (specifically, North America). The group is now absent in the northern hemisphere, except for a few species of Agathis in Malesia which possibly spread there from the Sahul region in relatively recent times. That said, I agree that the sentence is confusing and I have removed it (unless someone else objects). The use of "present" or "recent" in the geological range template is a matter of convention, I think. Best take up the matter in Template talk:Geological range, as most articles use "recent."-- OBSIDIAN†SOUL 04:41, 5 December 2016 (UTC)

message: Somebody has written to Talk:Cyclobalanopsis:
"It is ONLY the Flora of China that treats Cyclobalanopsis as a genus. Almost all botanists incl. the ones responsible for the genus Quercus consider it a subgenus. In my opinion Wikipedia should follow the currently most common opinion and add Cyclobalanopsis as a subgenus of Quercus."
I agree on this. For example, Angiosperm Phylogeny Website (http://www.mobot.org/mobot/research/APweb/welcome.html) and any of the taxonomy databases (like http://www.ncbi.nlm.nih.gov/Taxonomy/taxonomyhome.html/ and http://www.ars-grin.gov/cgi-bin/npgs/html/tax_search.pl) do not support the genus Cyclobalanopsis.

Talk:Iron(II) fluoride

message: The main text says that FeF2 is a "green crystalline solid," with a colorless tetrahydrate, whereas the infobox says it's a "red-violet transparent crystal." I think one would have to be color-blind to reconcile the two descriptions. I know of inorganic compounds that change color when hydrated or not, or due to fluorescence, but this doesn't seem to explain the discrepancy in this particular case. Which description is right? A brief Google search didn't shed any light upon this subject. It did show, though, that ferrous salts are usually green, as are nickel ones, and nickel (II) fluoride is green. So, I'm more tempted to believe the main text description, but can anyone confirm the color of ferrous fluoride? --UrsoBR (talk) 02:33, 12 November 2013 (UTC)
replies: text: The "green" may have been a blid guess from the pale green color of the solution, and "red-violet" may have been vandalism.  All references I have seen say that both the solid anhydrous and tetrahydrate are white (colorless).  Fixed. --Jorge Stolfi (talk) 13:06, 13 November 2016 (UTC)
replies: text: That was my conclusion.  High spin ferrous would be expected to be that way.  The other thing that I learned is that a lot of work has been reported on the anhydrous (>1000 hits in SciFinder), but almost nothing on the hydrate.  The usual problem with hydrated fluorides is that they are contaminated with isostructural hydroxides.

In order to achieve optimal yields the gap between the wire and the solid krypton should be 1 cm, giving rise to a temperature gradient of about 900 °C/cm.
By grade school arithmetic, that puts the krypton at -220 °C (or about 50 K).
