    • (edited Dec 21st 2023)

    Seeing the page history, there have been two weird edits to this page on 31 July 2023. The first made a couple of deletions. The second seems to have restored them. But to be safe I have rolled back to version 304 before that event.

    I am currently in China, visiting the Yau Mathematical Science Center. This alerts me of how inconvenient some of the nLab’s habits are for users from here (which in I knew in theory, but one gets a better sense of it when actually affected in practice).

    For instance the search functionality at the top of the HomePage does not work here, since no Google service is available here.

    We should accompany the search box at the top of the page by alternatives which use other search engines.

    I would change it myself, but right now I am not actually sure how to do it. Our code is

      <form  name="gsearch" method="get" action="https://www.google.com/search"><input type="text" size="30" name="as_q"/><input type="hidden" name="as_sitesearch" value="https://ncatlab.org/nlab/"/></form>
    

    How to adjust this for other engines?

    In the Sandbox I have tried this code with the url exchanged for that of Bing, but that alone doesn’t help. Probably also the “method” field etc needs to be adjusted?

    If anyone knows about how this works, I’d be grateful for hints.

  1. The apostrophe in “Urs Schreiber’s” was rendering (in my browser) as an opening single-quote, so I changed it from character ’ to character ‘.

    Added:

    The following custom themes are available for the nLab:

    diff, v311, current

  2. Due to recent editing behaviour on the nLab, I’ve added a little note to the main HomePage explaining that original research is banned and that the nLab should only be used for existing concepts in the literature:

    Note: In the past, people have used the nLab for their own personal notes and original research. This purpose has since been depreciated from the nLab. Please only add material that is discussed in the existing literature to the nLab.

    diff, v312, current

  3. I also added “and please add references to the literature for the added material” to the note.

    I edited the following paragraph about MathML, but perhaps it should be deleted altogether, since MathML is supported by pretty much all browsers these days:

    The nLab should be viewable and editable in any modern web browser on any device. For technical reasons, modern browsers that are able to render MathML, such as Firefox 2+, Chrome/Chromium/Edge 109+, Safari 10+ may render very large pages quicker than older browsers, but these pages are few and far between, and most people will be able to use the browser of their choice.

    No Madeleine, this is not true. We certainly want people bring good ideas with proofs. The problem is not originality, but the lack of substantiation.

  4. Is this note better?

    Note: In the past, people have used the nLab for their own personal notes and unsubstantiated original research. This is no longer allowed the nLab. When you add add material to the nLab, please add references to the literature to substantiate the added material.

  5. missing “on” in second sentence. Corrected version:

    Note: In the past, people have used the nLab for their own personal notes and unsubstantiated original research. This is no longer allowed on the nLab. When you add add material to the nLab, please add references to the literature to substantiate the added material.

    diff, v314, current

  6. I also removed the following sentence from the first sentence of the Purpose section:

    Along with work of an expository nature, original material can be found in abundance, as can notes from evolving research.

  7. “add references to the literature” -> “include references to the literature in the article”

    diff, v314, current

  8. Done revising for now

    Note: In the past, people have used the nLab for their own personal notes and unsubstantiated original research. This is no longer allowed on the nLab. When you add material to the nLab, please also include references to the literature to substantiate the added material.
