I refer to this deleted question and my question is this:
Why was this question deleted rather than migrated to History of Science and Mathematics SE?
To summarize the deleted question: cites this book "How Einstein Ruined Physics" by Roger Schlafly, one of whose main premises seems to be the notion that Einstein was a fraud because Poincaré, Lorentz (not to mention, unwittingly, Maxwell himself) and others made important contributions to STR that were unacknowledged by Einstein at the time. The OP asked for an opinion as to how valid this viewpoint is.
Now the question was probably against the rules of this site owing to its opinion-dependent nature, but I was rather concerned that it was deleted as "Offensive" instead of being migrated to History of Science and Mathematics SE.
Maybe this question was trolling. Maybe it was genuine. Either way, the notion of Einstein's fraud can be soundly repudiated by discussion, not censorship. I wrote an answer that was upvoted thrice very swiftly: I emphasize that I really don't give the nether end of a rat about the reputation, but I do care that the arguments against a fairly fashionable idea in some circles couldn't be put, either by me or by someone else - I really don't care. The upvotes seem to say that people had valid thoughts on this question. Moreover, after I wrote my answer, several people made highly valid comments that I hadn't thought of and should also have been put to repudiate what the OP seemed to be implying (or seeking confirmation of). Like it or not, many lay people read this site and form opinions about science grounded on its practices. Some will take from this question's deletion the impression that bad ideas are censored rather than rationally repudiated and shown, with evidence, to be bad ideas as should, IMO, be the wont of scientists.
In deleting the question, we lost the chance to describe an important aspect of the scientific method. That is, science is a culture and we all benefit from the ideas of our forerunners. Hopefully we cite these other ideas, but sometimes they become deeply enmeshed in the culture and body of knowledge that we forget that there was a time before them. Add to this Einstein's odd, intense, somewhat isolated personality that lead to his being e.g. stuck in his building's elevator many cycles lost in his thoughts before realizing it was time to get off, you have someone who was perhaps a little less adept at citation than he might have been. Einstein - crucially - lived in a world where communication was very different from today and it was not as easy to keep abreast of ideas. I recall a sign in my faculty library in the 1980s advertising a course in Dialog (an ancient forerunner to the WWW) bearing the slogan "Information Revolution Got You Down?" In those days I certainly felt this way, much more so than now where, thanks to the WWW and decent search engines, I do not feel overwhelmed by information.
So science is a culture that shares ideas that everyone benefits from. Einstein was no different from any other scientist in this way. Does that make Einstein a fraud? Absolutely not: without the protagonists, including Einstein, there is NO culture and there is NO science. The author of the book in question as a professional geometer liked Poincaré's insights into special relativity and the geometric / group theoretic description more than Einstein's. If the truth be known, probably I do too. So what. We all think differently. My understanding of the history is that Einstein was first to uniquely take time dilation as just that: a real effect on time itself rather than arising from Lorentz's "local time" which was not taken as being "true" or "real": Poincaré himself described it as having no meaning by itself and resulting only from convention. Moreover, as one commenter pithily put it, Einstein's contribution was hardly only special relativity, or even only GTR and STR put together.
I can understand the viewpoint that the question was not a good fit for this site. I disagree that challenges such as the OP's to mainstream viewpoints can be offensive. He/She attacked no-one personally on this site. I disagree with the question's deletion and believe that it should have been migrated to History of Science and Mathematics SE.
I've banged on enough, so could someone please give any further insight into why this question was deleted rather than migrated?
