Aristotle's axiom is weaker than the parallel postulate.
The very existence of Wikipedia is proof that there are more people in the world wanting to build than to tear down. Were that not true, vandals would have overwhelmed and destroyed us years ago.
I believe knowledge should be beautiful! If you need any help with diagrams just let me know and I'll see what I can do.
My main focus of work lately has been the Group Testing article, which recently passed its GA review. Next I'm hoping to take this article to featured, so any suggestions or feedback is welcome.
I am also currently recording a spoken version of the Earth article. You can find my script here.

Here you can see most of the graphical work that I've uploaded to date (almost entirely SVGs) in reverse chronological order. Note that many of these are vectorisations of previous works. In these cases, click on the image to find a link to the original author. I do all my vectorisations by hand to ensure the best quality (compare this and that to see what I mean: one tenth the file size, incalculably better quality). For a full list of uploads see my upload list.

Agood article is an article that has passed an independent review ensuring that it is well written, verifiable, broad, neutral and if possible, illustrated. You can identify good articles by this icon: 
, which appears in their top right corner. Below you can find a list of the good-article reviews that I've conducted, as well as the template that I use to do them.

Vector Bloom is an ongoing initiative of mine hosted once a month. The idea is to draw 10 or more diagrams (vectorisations are permitted) on a single day. Then I'll add comments on how 'the bloom' went.
Update: This initiative has been canceled. Contrary to it's original aims, Vector Bloom ended up decreasing productivity. This is because it incentivised 'saving' vectorisations for later (so I could tackle them all at once). This then created a barrier: if I wanted to do a vectorisation, I would be committing myself to doing 10, or I'd be wasting the ones I did. Anyway, I'd like to find some other way to increase my productivity in this area, but until then, I'll just be working sporadically as usual.
Bloom 1 (14/2/2017) |
|---|
|
This bloom was dominated by 'arrow style' diagrams, and I feel like I learnt a lot about easily placing text. I finally started using one of Wikipedia's available fonts for the first time (letter placement issues be gone!). I also drew some icons that we're hoping will make it into a new Wikiproject banner template. All in all it was a pretty successful bloom, though the uploading process to a lot longer than I had anticipated. |

Links to information on the internal history and evolution of Wikipedia. My current task is to hoover up the primary sources in meta:Category:Wikimedia history. There are also some interesting pages in Category:Wikimedia hardware.
Secondary sources are those which provide any amount of commentary or summary of events. If known/meaningful, the date of the topic under discussion is written in (round brackets), and the date at which the secondary source was written is written in [square brackets].
Timelines are chronologically ordered lists of events with minimal commentary.
|
Primary sources are direct records/logs of events as they happened with no commentary.
The following are collections of very early discussions. The dates of the discussions are difficult to ascertain, because they have all been moved at least once and many of them are from very early era Wikipedia. Additional date information can be found on their talk pages.
Indices are lists of links to primary or secondary sources without commentary (other than possibly dates) attached.
