Please check out my re-written introduction to Spacetime[edit]

I've tried to address the issues that you and others have raised on the talk page, by re-writing the Introduction. Let me know how well I've succeeded. Thanks! Stigmatella aurantiaca (talk) 13:50, 26 March 2017 (UTC)[reply]

It reads very well, I do have a couple of suggestions:

Mention that general relativity relies on the fact that space and time are on the same footing? Space-time doesn't merely simplify some theories, for some it is required. Without a combining space and time one cannot write quantities which are the same in any frame of reference.
It could do with a citation or two. When I read it I felt like the sentence about Special Relativity inspiring Hermann Minkowski needed to be cited.

Aside from these things I think you've done a good job. I feel strongly that any layman should be able to head to Wikipedia if they decide they want to learn the basic keywords that scientists use. Eradicating 'manifold' from the introduction of this article is the first step towards doing that. PhysicsSean (talk) 17:47, 26 March 2017 (UTC)[reply]

I've reworded on the basis of yours, Greg's, and a friend in Norway's suggestions, so that the Introduction should read better. Stigmatella aurantiaca (talk) 15:00, 8 May 2017 (UTC)[reply]

Citations have been improved in the Introduction. MOS does not require citations in the lede, provided that they exist at appropriate points in the main body of the article.

The Introduction is quite long (much longer than the March 26 version that you read), so I've linked each level-3 and level-4 subsection in the Introduction to a brief summary in an associated stub article, Spacetime (Introduction section) summary. I hope that the navigation back-and-forth between the main article entries and the summary entries is intuitively obvious.

A new section, "Basic mathematics of spacetime", is still under development, so I am not yet officially soliciting comments. The math in this section is limited to algebra (except for two uses of calculus ["dr/dt = 0"] in the Transverse Doppler shift section that I couldn't see how to avoid). But try out what I have so far. Stigmatella aurantiaca (talk) 15:00, 8 May 2017 (UTC)[reply]

Could I have your thoughts on this proposed edit to Spacetime?[edit]

Back in March 2017, you were one of the commentators who led me (under a previous user name, which which I was forced to abandon when I lost the password and password recovery failed) to do a complete re-write of the article Spacetime.

I was wondering if you could comment on the following discussion? Talk:Spacetime#Existing_articles_on_(Introduction_to_the)_mathematics_of_general_relativity_are_virtually_useless

I believe that you should be well-qualified to comment on the actual scientific merits of the material that I have proposed adding, which User:Zefr has reverted.

Thanks!
