To enter, please submit a link to your problem/note/wiki in the comments. Add (at most) one image, if you feel like it.
The problem/note/wiki must be related to Physics, Chemistry, Mathematics, Economics, Biology or Computer Science in some way. Needless to say, it must also relate to the contest theme.
Wikis are not jokes. If you wish to submit a wiki, please do not compromise with the integrity of wiki articles.
We are looking for the best content, not authors. So, you may submit more than one content.
The score of a content will be determined by number of upvotes. Winning entries will be selected with a probability directly proportional to the score of the submission.
The contest ends on February 14, 2017.
Keep the comment sections clean and constructive.
