New page

''[[On Physical Lines of Force]] → Rendering test''

A page for checking that this MediaWiki installation renders the wiki correctly. '''If everything below looks right, the import is complete.''' Delete this page once you are satisfied — it is the only page nothing links to.

== 1. Inline mathematics ==

Written as <code><math> ... </math></code>. The magnetic force has components <math>\alpha, \beta, \gamma</math>, the current components are <math>p, q, r</math>, and the permeability is <math>\mu</math>. A fraction inline looks like <math>\frac{d\gamma}{dy}</math>.

== 2. Displayed mathematics ==

Written as <code><math display="block"> ... </math></code>.

<math display="block">\nabla\times\mathbf{E} = -\frac{\partial\mathbf{B}}{\partial t}</math>

== 3. Numbered equations ==

texvc rejects <code>\tag</code>, so equation numbers are set inside the maths with <code>\qquad\qquad\mathrm{(54)}</code>. Every numbered equation in this wiki uses that form.

<math display="block">\frac{d(\mu\alpha)}{dt} = \frac{dQ}{dz}-\frac{dR}{dy} \qquad\qquad\mathrm{(54)}</math>

== 4. Multi-line alignment ==

<math display="block">\begin{aligned} \nabla\cdot\mathbf{D} &= \rho \\ \nabla\cdot\mathbf{B} &= 0 \\ \nabla\times\mathbf{E} &= -\frac{\partial\mathbf{B}}{\partial t} \\ \nabla\times\mathbf{H} &= \mathbf{J} + \frac{\partial\mathbf{D}}{\partial t} \end{aligned}</math>

== 5. Underbraces ==

Used on [[On Physical Lines of Force/Part I/Prop. III|Prop. III]] to label the five terms.

<math display="block">X \;=\; \underbrace{\mu\gamma\,q \;-\; \mu\beta\,r}_{\text{the force on currents}} \;-\; \underbrace{\frac{d\,p_{0}}{dx}}_{\text{simple pressure}}</math>

== 6. Mathematics in a table ==

{| class="wikitable"
! Maxwell !! modern
|-
| <math>\mu\alpha, \mu\beta, \mu\gamma</math> || <math>\mathbf{B}=\mu\mathbf{H}</math>
|-
| <math>p, q, r</math> || <math>\mathbf{J}</math>
|-
| <math>F, G, H</math> || <math>\mathbf{A}</math>
|}

== 7. Mathematics in a list ==

* the divergence: <math>\frac{d\alpha}{dx}+\frac{d\beta}{dy}+\frac{d\gamma}{dz}</math>
* the curl, one component: <math>\frac{d\gamma}{dy}-\frac{d\beta}{dz}</math>
* absolute values: <math>\vert\mathbf{E}\vert = c\,\vert\mathbf{B}\vert</math>

== 8. A figure ==

[[File:OPL-fig-plate-fig2.svg|thumb|center|680px|Vortex cells and the particles between them]]

== 9. Ordinary formatting ==

This sentence has '''bold''', ''italic'', <u>underline</u> and <code>monospace</code> in it, followed by inline maths <math>\mu = 1</math>, then more '''bold'''.

<blockquote>
A block quotation, which this wiki uses for every verbatim passage from Maxwell.
</blockquote>

----

== Troubleshooting ==

'''Maths shows as raw markup.''' The Math extension is not installed or not enabled. Install '''Extension:Math''', add <code>wfLoadExtension( 'Math' );</code> to <code>LocalSettings.php</code>, then run <code>php maintenance/update.php</code>. All 935 equations in this wiki were validated against texvcjs — MediaWiki's own TeX checker — so none should be rejected.

'''Figures do not display.''' The 19 SVGs must be uploaded separately: an XML import carries page text only. Use <code>Special:Upload</code>, or run <code>php maintenance/importImages.php /path/to/images</code>. SVG uploads also need <code>$wgFileExtensions[] = 'svg';</code> and, for rasterised thumbnails, <code>$wgSVGConverter = 'rsvg';</code>.

'''Links are red.''' Every internal link points at a page title under <code>On Physical Lines of Force/</code>. If the import was partial, re-run it. Titles are case-sensitive after the first letter.

'''Sub-page breadcrumbs are missing.''' Optional: add <code>$wgNamespacesWithSubpages[NS_MAIN] = true;</code> to <code>LocalSettings.php</code> for automatic parent links.
