Peculiarly Interesting Things I Found On This Site Thus Far
1.) The Null Glitch

Copy and paste the following string of characters into the source code of a page, then publish your edit.

\(\color{#FF0000}{😃}\)

After publishing your edit, hit edit again and in visual mode, put your cursor to the sharp right of the emoji and hit backspace once. This will cause a character to appear in it's place which resembles a question mark inside a gray diamond. Now publish your edit; the entire page's contents should be deleted and replaced with the word "null".

2.) The Null-Text Error

A LaTeX script which has a command to display an empty text string such as

$$\text{}$$

will display as error message when the page attempts to display it, which is as follows:

$$\text{}$$

3.) Squares Aren't Actually Square

With the MathJax command \(\square\) or \(\blacksquare\) you can create squares, but what you probably don't know is that these squares are actually irregular curves ! Here is a comparison.

4.) Saving Equations As Pictures

When there is LaTeX code such as $$\omega^{\omega^{\omega^{.^{.^{.}}}}}$$, you can save the resulting display on the page as an image by right clicking, which is how I managed to take this photo:



Unfortunately, this does not work for LaTeX' more versatile counterpart MathJax.

5.) YouTube Embedding

With the code [URL of YouTube Video] you can embed YouTube videos in a wiki page, which will automatically be uploaded to the wiki, but just by adding an extra space to the second "youtube", (i.e. the code [URL of YouTube Video] ) you will produce a video that can be accessed but none the less is not a part of the wiki, as shown below. Of interest to is that anything placed after the embedding of the video in the source code will not be visible either in visual mode or in non-edit mode. If you do attempt to place text after the video you will still see the video but it will not play, unless you insert a title " ==[Ending Character Portion of YouTube URL]== " after the video.

This is also the reason I have kept this fact the last one on this page.
