1$\begingroup$ It seems that you are mixing two ralted but seperate consepts, coordinate charts and frames. It is also not clear what your question is. $\endgroup$MBN– MBN2026-03-31 11:41:08 +00:00Commented 16 hours ago

$\begingroup$ Yes, the definition from Landau&Lifshitz is about coordinate charts, I think, right ? $\endgroup$CarloC– CarloC2026-03-31 12:15:39 +00:00Commented 16 hours ago

1$\begingroup$ What is the question? $\endgroup$Dale– Dale2026-03-31 12:18:29 +00:00Commented 16 hours ago

1$\begingroup$ So are you making a point and not asking a question? If so, that isn’t what this site is for. This is a question and answer site. Not a discussion forum. You might consider physicsforums.com instead $\endgroup$Dale– Dale2026-03-31 13:12:05 +00:00Commented 15 hours ago

2$\begingroup$ Ok, so on this site you need to write a question to which the feedback you want would be the answer. That needs to be edited into the question itself, not the comments. $\endgroup$Dale– Dale2026-03-31 13:19:34 +00:00Commented 15 hours ago

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. quantum-mechanics), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
