Purpose of the Document
This is a Audio slides Wiki2Reveal Test Page that is used check converting a Wiki page "on the fly" into a reveal presentation.

Audio Comments in Section
Audio Comments in the text can be used Now a Rock Beat for drums
 * to add additional audio comments to a slide or
 * to play audio samples in the reveal presentation

Splitting Slide with Audio
This slide is splitted by audio sample, first Accordion sound Press play on audio player and hear the accordion sound Again the Rock Beat for drums

Inline Math Expression in Slides
The condition that U be simply connected means that U has no "holes" or, in homotopy terms, that the fundamental group of U is trivial; for instance, every open disk $$U=\{ z: |z-z_{0}| < r\}$$ qualifies. The condition is crucial; consider

Block Math Expression in Slides

 * $$\gamma(t) = e^{it} \quad t \in \left[0,2\pi\right]$$

which traces out the unit circle, and then the path integral


 * $$\oint_\gamma \frac{1}{z}\,dz = \int_0^{2\pi} { ie^{it} \over e^{it} }\,dt= \int_0^{2\pi}i\,dt = 2\pi i $$

is non-zero; the Cauchy integral theorem does not apply here since $$f(z) = 1/z$$ is not defined at $$z = 0$$.
