Re: How to nip erroneous content in the bud?

Kathryn Haas

This was the message I got from Steve Contakes (who is brilliantly detail focused). If we can get a list of pages, we can correct the error on all pages, unless you have a better suggestion.
Thanks!

Kathryn,

I found another error on the site. While using Inorganic Syntheses to write problems for the nomenclature section I noticed that the formulae there and just about everywhere else didn't agree with the rules for writing of formulas for coordination compounds given on several Chem.libretexts pages.  From the pages on our site it looks like we were misled by some students at UC Davis who wrote an article on the site saying that anionic ligands should be placed before neutral ones and then backed it up by a snappy graphic.

I am a bit ashamed to admit that I looked deeply enough into the nomenclature rules to say this but it turns out that not only is there is no such rule, the IUPAC red book expressly repudiates the practice:

IR-9.2.3.1 Sequence of symbols within the coordination formula

(i) The central atom symbol(s) is (are) listed first.

(ii) The ligand symbols (line formulae, abbreviations or acronyms) are then listed in alphabetical order (see Section IR-4.4.2.2).5 Thus, CH3CN, MeCN and NCMe would be ordered under C, M and N respectively, and CO precedes Cl because single letter symbols precede two letter symbols. The placement of the ligand in the list does not depend on the charge of the ligand.

The error persists on the following chem libre pages, possibly among others:

Re: How should we license figures created for LibreTexts construction?

Delmar Larsen <dlarsen@...>

Yeah. There is a requirement from the Dept. of Ed. grant for it to be CC BY. if the image is created for this grant, then that is the preferred license. If content is remixed from other sources, then this doesn't apply.

Re: How to nip erroneous content in the bud?

Delmar Larsen <dlarsen@...>

If the content was transcluded or forked, then we can check the meta-tags for the source page ID. I have dreams of making this a bit clearer so we can see how content propagates through out our libraries. But, it is not at the top of our queue.

Which page and image needed updating?

How to nip erroneous content in the bud?

Kathryn Haas

One of our team has found some erroneous content, including figures, on Libretexts. Is there a simple way to find and replace any propagation of these errors on other pages (aside from a good old keyword search)?

How should we license figures created for LibreTexts construction?

Kathryn Haas

I noticed that an attribution place holder has been added to Figure templates. So far, I've just left all new content without specific license because I wasn't sure.

I hate to open up a can of worms, but is there a preferred license to use for figures created specifically for construction efforts? Or is it simply up to individual authors?

Re: Hypothes.is annotations not visible even though public

Delmar Larsen <dlarsen@...>

Which page(s) specifically. We added a "canonical" tag so to the hypothesis to address moving of pages (e.g., renaming). But, we should confirm this.

Re: Hypothes.is annotations not visible even though public

Kathryn Haas

Delmar,
Several faculty at Saint Mary's, including myself, are currently plagued by this same issue. It seems that some URL's have been changed (although I haven't changed them) and hypothes.is has lost track of the page and cannot link the annotations. It would be helpful if this could be fixed. Can you help?

Re: Contour integral symbol not displaying in equations

Delmar Larsen <dlarsen@...>

We will define the \oiiint code. So just use that for now and we can handle the specific code behind the scenes.

Re: Forcing equations to number

Delmar Larsen <dlarsen@...>

To use mathjax, you need to put the entire sentence into mathjax to get an automatic equation number.

Hi,

I have a text with a number of lines that contain formulas at the end and I want them to number
For example

This is a line with some mathjax $$X$$

and I want this equation at the end to autonumber

Looking for help

Re: Contour integral symbol not displaying in equations

Josh Halpern

\int\hspace{-2ex}\int\hspace{-3ex}\bigcirc~  works. You have to back space to maintain distances

Ah ok, thank you so much! I'll give that a go

smmuller@...

Hi Jasmine,
In Google Maps, after you find your location, click Share, then the Embed a Map tab, and copy the HTML.
Once you're in Libretexts and editing your page, in the top menu click View, and then Source, and paste the map's HTML where you want it.
Click View and Source again, and your map should be there on the page.
(If you really don't want to work with the page source, you can cheat instead - in the top menu click Elements, then Video. Click the Embed tab, paste in the HTML you copied from Google Maps, and click Insert Video. It will insert your map there.)

Jasmine Keane

Hi everyone,
i am trying to add a google maps feature to a project I am working on. Its a specific location but I cant figure out how to add it currently.

Thanks,

Contour integral symbol not displaying in equations

The contour integral symbol does not display when used in equations. The Latex code shows correct when using Mathpix, but on the Libretext page, double and triple contour integrals do not display the symbols. The code and page pics are attached.

0.5 \oiint_{\mathrm{A}} \overline{\mathrm{\underline S}} \bullet \hat{n} \mathrm{da}+\oiiint_{\mathrm{V}}\left[\left\langle\mathrm{P}_{\mathrm{d}}(\mathrm{t})\right\rangle+2 \mathrm{j} \omega\left(\mathrm{W}_{\mathrm{m}}-\mathrm{W}_{\mathrm{e}}\right)\right] \mathrm{d} \mathrm{v}=0

Thank you,

For the first page, it looks like the pathways are formatted as a definition list. The easiest way to fix it would be to just get rid of that - highlight the list, go to Elements, and click Definition List, and it should remove that formatting. (Unless you're asking how to edit the HTML/CSS/whatever controls that behavior?)

For the second page, you could try removing the http:// part of the link so you just have something like this:
