Test Page

## Welcome to the wiki playground

This page is a place for you to practice doing some edits and see what the effect is (using the workspace below). This is particularly beneficial for trying out some mathematics, which are typeset using the math environment. Studying this page will give you the very basics for editing a page on this site. More information on the syntax appropriate for all kinds of things (headings, fonts, math-mode, links, tables, etc.) can be found on the wiki-syntax page.

Here is an example of bold text, italic text and underlined text. A photograph can be inserted fairly easily using the insert image wizard. Here, I inserted a picture of me from the web.

It might even be useful to embed audio (or video) that is stored somewhere else. This is also quite easy to accomplish using the embed audio (or video) button.

Here's an audio example:

And here's a video example:

Of course, there will probably be some mathematical expressions on this site, so here is a sample (displayed) equation:

(1)
\begin{align} \rho _{\rm GJ} = -\sigma (r) \left[ (1 - \eta _{\ast }^2 {\kappa \over {\eta ^3}}) \cos \chi \right. + \left. {3\over 2} \theta (\eta) H(\eta) \xi \sin \chi \cos \phi \right]. \end{align}

The above is a displayed, numbered equation. The mathematics are typeset using $\LaTeX$ syntax, so if you already know $\LaTeX$, mathematics is a piece of cake. If an equation is labeled, it is easily referred to using [[ eref eqlabel ]]—so Eq. (1) is easily referred to.

Conversely, an inline equation is typed as follows: $E = mc^2$ is much more popular than $G_{\mu\nu} - \Lambda g_{\mu\nu} = \kappa T_{\mu\nu}$. Of course, just as in a $\LaTeX$ document, equations sometimes take up more than one line. Similar to $\LaTeX$, we use type="eqnarray" in the math environment to get

(2)
\begin{eqnarray} \lefteqn{ \cos x = 1 -\frac{x^{2}}{2!} +{} } \\ & & {}+\frac{x^{4}}{4!} -\frac{x^{6}}{6!}+{}\cdots. \end{eqnarray}

Of course, you will also want to appropriately reference your work. Again, similar to $\LaTeX$, we use a bibliography environment and then cite things using bibcite. For example, the first experiment to definitively demonstrate the existence of the photon was performed in 1985 by Grangier, Roger, and Aspect [1]. And in case you didn't know, a coherent state can be written as [2]

(3)
\begin{align} \left| \alpha \right>=e^{-\frac{1}{2}|\alpha|^2}\sum_{n=0}^{\infty} \frac{\alpha^n}{\sqrt{n!}}\left| n\right>. \end{align}

# Workspace

Feel free to modify anything between the lines in this workspace but please do not modify anything else on this page. I want to be sure there are always some working examples on this page!

Have fun!

~Hey it's Lindsay- I've got everything all set up and ready to go!

Just figuring out-

thats way intense Brendan… I feel like you should show me how to do that… p.s. this is erin finally becoming a memeber….
