Experimental Text
Some suff.

Her are examples of formatting in bold, itallic and both together.

Note: Do not use Section Level 1 headers in articles.

Formatting in Boxes
Stuff in a box. Note the change to a fixed width font. Also be aware that lines of text inside a box do NOT automatically adjust to the width of the browser. To add a carrage return in the Visual Editor in a box, use Shift-Return, otherwise you start a new box. In the normal Source Code Editor, create boxes by starting lines with a space character. In the Visual Editor, a box is called a 'Preformatted Section'. The option is the 2nd tab from the left at the top of the screen.

This line does not have a leading space charcter, so it doesn't appear in a box.

This is a code box:. This is created by surounding its contents with. The Visual editor dosn't suport this directly.

Note that ordinarily, just placing commands like into the text will activate them, not display them as text in the way they are in this sentence. To make them (or any other formatting command) visible as normal text, insert them between and  commands. These force everything between them to be treated as regular text.

Formatting for Science
This is a short excerpt from the article on Einstein's General Theory of Relativity copied here to illistrate mathmatical formulae in action:

On the left-hand side is the Einstein tensor, a specific divergence-free combination of the Ricci tensor $$R_{\mu\nu}$$ and the metric. Where $$G_{\mu\nu}$$ is symmetric. In particular,


 * $$R=g^{\mu\nu}R_{\mu\nu}\,$$

is the curvature scalar. The Ricci tensor itself is related to the more general Riemann curvature tensor as


 * $$R_{\mu\nu}={R^\alpha}_{\mu\alpha\nu}.\,$$

On the right-hand side, $$T_{\mu\nu}$$ is the energy–momentum tensor. All tensors are written in abstract index notation. Matching the theory's prediction to observational results for planetary orbits (or, equivalently, assuring that the weak-gravity, low-speed limit is Newtonian mechanics), the proportionality constant can be fixed as κ = 8πG/c4, with G the gravitational constant and c the speed of light. When there is no matter present, so that the energy–momentum tensor vanishes, the results are the vacuum Einstein equations,


 * $$R_{\mu\nu}=0.\,$$
