Deletion of Horizontal versus vertical

Comment: Keep'''. The author here again. Thank you Ducknish for toning down the  issue. The article is fresh but there is nothing original in it except the use of diagrams which I mostly drew myself. But to take your main point, I disagree. The concepts of horizontal and vertical are inter-related. One is defined in terms of the other with some degree of freedom as to which is the primary concept. By discussing them in one place, by contrasting ''horizontal'' with ''vertical'', the ''symmetries'' and the ''asymmetries'' can be displayed, as the article illustrates. Misconceptions that arise from not appreciating the inter-relationship between the two concepts can be dispelled by discussing the two together. It should be a useful article for the physics teacher and student. But this is not an argument against improving my article or merging with other wiki articles. I have already mentioned the long standing wiki article Horizontal plane which my article complements

Comment: The article is  to a certain extent but also a topic that isn't really worthy of inclusion. There's no real justification for having an article comparing horizontal and vertical when they each have their own article to be seen
