Discussion: Lorentz invariance of certain zero angles
- Thread starter Pete
- Start date
any chance of clarification for us laypeople?
don't think i could understand if it was explained, but its worth a shot..

Once the debate started , we can no longer answer. Watch the Debate thread, the answers are there.
Well, I addressed the scenario and I provided the calculations. There isn't much left , unless you disagree with the calculations.
I'd hardly call that a calculation. It's pretty much you stating a result.
This is because the derivation is trivial, all the information is there. I would be more than happy to explain it in greater detail, what part did you need help with? Please let me know and I will be more than happy to explain it to you.

You agreed to the rules, I'd like you to stick to the agreement.
I will proceed as agreed, and make sure we agree on the scenario before going any further.
Go ahead. Did you understand the explanation? Because, if you didn't or if you disagree with it I do not plan to waste another 100+ posts.
Hi Tach,
As agreed in the proposal thread, we will go one step at a time, doing all we can to make sure we understand each other before proceeding.
Also, I notice that you edited your post twenty minutes after posting, with no explanation. Please stick to the rules we agreed on in the proposal thread.

The darn thing has no spell checking, in a long post it is tough weeding out the mistakes.
Let's keep the debate/discussion in this forum, I am getting tired switching between the two in trying to answer you, Trippy, AN, etc. OK?
Good idea.
Tach, I've just noticed that did a major edit to [post=2863701]post 4[/post] while I was responding to it.
We agreed not to do that:
OK? No edits more than 5 minutes after posting. No edits except for spelling mistakes or similar.
Preview your posts before committing them.
If you want to make a significant change after posting, PM me or post to the discussion thread first.
Please, if we can't stick to the rules we agreed on, I'm worried that the debate will descend into another confused jumble of misunderstandings.

We agreed not to do that:
- Posts may not be edited except:
- Within 5 minutes of posting
- For typographical errors only
- If permission is given by the other person by PM or the Discussion thread.

Hi Tach,
We seem to have entered our first side issue, that of coordinate dependence.
With your permission I'd like to edit the opening post to add 1.1 - Coordinate dependence to the list and set it active, and make 1.0 - Scenario pending.
I apologize, I should have done this before responding to the Debate thread.
Also, I notice that you aren't using the post headings we agreed to use. Please do so.

Please add it.

I don't think Tach has grasped the notion of coordinate dependence. A vector is coordinate dependent (if you don't believe me write a general vector down and perform a coordinate transformation). An example of something that is coordinate invariant is the Ricci scalar which one can show is the same regardless of the coordinate system in which it is computed.
