Mulliken/Orbital
Hi, I hope it is appropriate to ask you to have a look at the discussion page of the "Molecular orbital" article.

Thanks in advance! —Preceding unsigned comment added by 134.176.250.16 (talk) 23:15, 15 February 2010 (UTC)

It would be more appropriate if you signed your comments and changes. Laburke (talk) 02:17, 2 May 2010 (UTC)

Woodbury Creek
I received your email. I do not operate CorenSearchBot. (In fact, I don't run any bot at all.) Your initial article was flagged by CorenSearchBot for being a copyright violation. I reviewed it and determined that it appeared to be copied from another website, which is not permitted. So I deleted it. It was then recreated, but the entire article was a link to another website. Somebody else revised it but it was deemed by the community to be below the threshold standards for inclusion here, so it was deleted. You are free to recreate the article, as long as you do not copy somebody else's words and give the article some content, e.g., where does it start, where does it end, how long is it, does it flow through any communities, is it navigable, is there a group that maintains or cleans it, does it have particular recreational uses, etc.

Take care and thank you for contributing to Wikipedia. -- But | seriously | folks   01:43, 27 May 2010 (UTC)

Flanders
Please take a look at Talk:Flanders. I saw that you edited it. I agree that that sentence is a bit confusing, so could you clarify it and/or reference it? And also, in the sentence "In contemporary Belgium, there is pressure to consider Flanders as the 'country of the Flemings' rather than just a region of Belgium." the "pressure" is a bit vague.

Ultima
Excuse me, I understood the source of our disagreement on phrasing in the Ultima (linguistics) article. I did undo too hastily, as you said, without looking at the talk page (as you did not look at it before your recent edit, judging by your edit summary). But I think your phrasing may not be the clearest, since it assumes a way of counting syllables that didn't seem obvious to me at first and might not be obvious to other Wikipedia readers if anyone is like me. That was why I introduced an (alas) less parallelistic phrasing that I hoped would be clearer after I undid your edit. — Eru·tuon 15:04, 21 September 2011 (UTC)

Spherical or cartesian coords for wave functions-- it doesn't matter to the graph or most places (just makes the radially symmetric equation easier to solve)
In atomic orbital you've changed nice simple |ψ|s into  |ψ(r,θ,φ)|s and I don't see that this helps at all, except to make it uglier and more complicated. After all, these are the very same graphs as if you used (say) |ψ(x,y,z)|s or any other spacial coordinate choice. Why don't you just change them back to the simpler form? Are you trying to show a spacial dependence? Just say they're being graphed in terms of spacial dependence and then you don't confuse the reader (by implication) into thinking that perhaps choice of coordinate systems makes some kind of difference.

 * Dear Sb, If you were the one to have submitted the graphics, I apologize in the Greek/Latin sense of apologia. Perhaps it can be left as ψ(x,y,z) so as to not get into too many details, except for the essential and important one. For at least 40 years, I have seen too many students get off on the wrong foot by not noticing that an orbital is a mathematical function that depends on the coordinates of ONE electron. Last night, I put the xyz or r,th,ph into the titles of these excellent graphics to emphasize the one-electron character of orbitals for beginning (and advanced) students in other fields. I thought someone would complain if I didn't put rtp for atoms and xyz for atomic orbitals as starting points for molecular orbitals. (I was even expecting a complaint from someone because cylindrical coordinates are used for diatomics.) No, I didn't want to make explicit reference to cartesian or polar, or cylindrical, or complex, or any other coordinate system. That's too much for a title, and you're right to complain if xyz is in one and rtp in another without explanation in the graphic. I find that many people (including myself) head for the pictures first. That's why I highlighted psi(xyz) and psi(rtp) there for the newbies. Please keep them there somehow. There's so much evne a high school student can learn by graphing one dimensional Ψ(x)=f(x)=y=exp(-Zx^2). BTW, if you or anyone else reading this would like to contact me, please make the effort to go to my talk page, see where I work, go to my web page, and contact me by e-mail. I'd be happy to discuss things that way. (Unless, of course, you are stuck in the mud of Woodbury Creek. I live close enough to throw you a line.)

Disambiguation link notification
Hi. When you recently edited Croconic acid, you added a link pointing to the disambiguation page DFT (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ* Join us at the DPL WikiProject.

Van 't Hoff equation
Are you aware that this equation is true even if $$ \Delta H $$ and $$ \Delta S $$ are functions of temperature? Their net effect is to cancel each other out, so the result is the same as if one were to assume that they are independent of temperature. — Preceding unsigned comment added by 131.111.184.8 (talk) 18:43, 7 February 2013 (UTC)

Dear Unsigned. After using the equation for over 40 years, I know that it is exact in the limit of dT, that is, when one knows the curvature of deltaH at a particular point T. All Physical Chemistry textbooks explain this, but they assume you know calculus. Some even give ways of estimating deltH at a new T using Kirchoff's Law assuming constant molar C over T. This usually gives a better estimate of a new K instead of using the tabulated deltH value at T=298. After teaching the equation for over 30 years, I have from time to time heard the error that the equation is true because the S and H temperature variation effects cancel each other out. The student also usually thinks that the "standard" in standard deltH means at T=298. The major reason why the equation is so valuable even though deltH can vary ca. 5-10% over deltT=300K is that you are graphing lnK to 1/T, essentially differences in powers of 10 of K to differences in thousandths of 1/T.

Thank you for the clarification, much appreciated. - Unsigned

Europe 10,000 Challenge invite
Hi. The WikiProject Europe/The 10,000 Challenge has recently started, based on the UK/Ireland The 10,000 Challenge. The idea is not to record every minor edit, but to create a momentum to motivate editors to produce good content improvements and creations and inspire people to work on more countries than they might otherwise work on. There's also the possibility of establishing smaller country or regional challenges for places like Germany, Italy, the Benelux countries, Iberian Peninsula, Romania, Slovenia etc, much like The 1000 Challenge (Nordic). For this to really work we need diversity and exciting content and editors from a broad range of countries regularly contributing. If you would like to see masses of articles being improved for Europe and your specialist country like WikiProject Africa/The Africa Destubathon, sign up today and once the challenge starts a contest can be organized. This is a way we can target every country of Europe, and steadily vastly improve the encyclopedia. We need numbers to make this work so consider signing up as a participant and also sign under any country sub challenge on the page that you might contribute to! Thank you. -- Ser Amantio di Nicolao Che dicono a Signa?Lo dicono a Signa. 09:27, 6 November 2016 (UTC)
