304:"Since there is already an article on Special Relativity, which includes an introduction, why do we also need a separate article on "Introduction to Special Relativity"? This article is almost entirely unsourced. It seems to be just a place where people can come to present their own personal ideas about special relativity. I don't think there's anything in this article that isn't already in the article on special relativity (other than some things that don't belong in Knowledge (XXG) at all). Shouldn't this article be proposed for deletion?" 258:"...in the case of special relativity, there happens to be a demand for jump-in-introductions. So we find many in the literature. Unfortunaly, most are just rubbish and merely present the author's misconceptions and misunderstandings about the subject. The more correct you want the treatment of an advanced subject to be, the less accessible it will be for the lay person. That is why, in my opinion, this article should not be here. It will never serve its purpose." 943:. These intro articles were a bit of a fad in the sciences in 2005-6ish. They're difficult to write and most look like they haven't been maintained all that well. It may be that they've outlived their usefulness with better resources available on other projects aimed at the same audience. I wanted to vote keep on this one, but on reading the article I don't think this is salvageable, even if the topic might be. Time for 55:. There is no consensus for any specific outcome (delete, redirect, merge or keep), but there is consensus for the view that we should not have a separate article about this. So I'm closing this as a redirect as the least destructive "not keep" option, allowing any content deemed worthwhile by editorial consensus to be merged from the history to elsewhere. 1355:. As noted by multiple people, this article is still too technical to be legitimately called an "introduction". However, this means that the article needs work, not deletion. These separate "Introduction to..." articles are not forbidden on Knowledge (XXG) (just type "Introduction to" in the Knowledge (XXG) search box). In fact, 290:"The article currently veers between elementary examples (eg passengers on a train) and mathematical proofs. While these two styles are suited to text books, though for widely separated age/competency classes, they are insufficient in style and gradation to satisfy the needs of an encyclopedic article." 601:
It is completely encyclopedic in its writing style, explaining the essence of the theory in non-mathematical fashion using simple explanations aided by well-chosen figures and insightful analogies that have long been standard in popular expositions of this subject, supported by 49 inline citations to

This article was started in March, 2005 with noble intentions. It was to be a mostly non-mathematical, introductory text written on a level comparable to a science article that one might find in the science section of the New York Times, that an educated "general reader" without a current background

For a general audience it's appropriate to use high school algebra accompanied by ample discourse and explanation. This is what the article tries to do. I know it is possible for this to succeed, because I learned special relativity while I was taking algebra in high school, before I knew basically

I could answer a lot of these objections (e.g. "Minkowski space" is defined and thoroughly expounded on in the article, as are the differences between Galilean and Lorentz transformations, etc.) but really, there is no policy-based objection here. At worst, even if these objections were valid, they
1072:
The article only manages to avoid math by throwing a lot of undefined terms at the reader. What does a rotation in Minkowski space mean? What really is a "transformation"? What are the differences between Galilean and Lorentz transformations? What are Maxwell's equations and Dirac's equation about?
1048:
Since by definition rotations must keep the distance same, passing to a different reference frame must keep the spacetime interval between two events unchanged. This requirement can be used to derive an explicit mathematical form for the transformation that must be applied to the laws of physics

An article on Knowledge (XXG) should be an introduction in no small amount (by definition of an encyclopedia article), and the lead of an article an introduction to the article-proper. The deletion-leaning persons above convince me that this article cannot be saved. However, I think a
