From Wikipedia, the free encyclopedia

Hi. My name is Dedhert.Jr. I am a Wikipedia editor contributing here by glossing articles to be suitably referenced articles; my contribution is mathematics, especially in polyhedral articles. Over the past months, I have gained many experiences from events or incidents: how the tensions between users look like, how to resolve a problem, and many more. Whenever I contribute here, some users may look at my horrendous action; whenever it does, giving a warning notification is sufficient to remind me how I behaved here (and I will try to fix it).

I also want to join WikiProject, but it could be a problem for me if my language is extremely abysmal^[a] and lack knowledge of the subject. Because of these problems, I might never become a good editor, so I personally made up my mind to improve them both.

As I mentioned before, my favorite subject is mathematics, and I love to make some improvements to the articles, especially to become GA, FA, or FL. The following is my improvement of the article that has GA status:

Square pyramid

The DYKs:

"... that square pyramids can have different shapes, and pyramidologists have put forward multiple theories on which of these shapes was used for the Egyptian pyramids?"

Some of my tools here:

Some lists

Whenever I feel bored, I sometimes come to the Category:GA-Class mathematics articles and Category:FA-Class mathematics articles, checking if there is an update of the significant number of GA. All of these articles may listed in the following specific sections.

GA
