Okay, that makes a lot of sense. I can see that a person might interpret an answer of x=+/-ct as two conditions--for the light on the positive axis x=ct; for light on the negative axis x=-ct, as pointed out by the author. This suggests to the reader that we are talking about light that...
I like the way you think Kwestion :approve:
The symbols make me wonder if the presentation was made by the author first working the problem backwards on scratch paper, then reversing the thought process for the published presentation.
Maybe behind the scenes, the math was performed in...
I'm trying to follow along with Simple Derivation of the Lorentz Transformation, but am having some hurdles.
I'll be referring to step (5) which states:
x'=ax-bct
ct'=act-bx
In paragraph marked 6, I see that the author tries to get eqn (5) to describe motion of the K' frame. This is an...
I started to study Simple Derivation of the Lorentz Transformation
In this derivation, I gather that there are two rays of light being tracked--one going to the right of the origin and one going to the left of the origin.
The right-going light is described by x=ct and x'=ct'.
The...
I'm not sure about the reliability, so thanks for asking about the source. Here's a link to the paper: http://worldnpa.org/pipermail/memberschat_worldnpa.org/attachments/20100506/167ccaf1/attachment.pdf"]One-Way[/PLAIN] Light Speed Measurement Using
the Synchronized Clocks of the GPS by...
Thanks for your reply.
I wouldn’t expect a non-interfering apparatus to affect the measurement by definition :smile:. My understanding is that vacuums don’t contain mirrors. My original device contained a mirror/splitter which interrupted the vacuum.
I wouldn’t initially think that it would...
Hello, I'm looking to understand the concept of the constancy of the speed of light. In particular, I think I need to understand what is meant by the speed being constant for all observers. Even more particular, I'm looking for experimental evidence that I can understand that will show me that...
Thanks to all. Lots of valuable replies. I think I now have firmed up where I have been parting with what should seem obvious (Stacy's observation translating to Trent's experience). Thanks for patience and willingness to get through. I willl have followup questions later and hope I'm as lucky...
Something's still nagging me to think that the words in blue are essential:
Let’s now consider a passenger on the moving train. The passenger will be Trent, who is located at the center of the train. In Stacy's frame, because Trent is moving with the train, he is approaching the light signal...
I think this is the area that I need to focus on for understanding.
I've been thinking that the story had its light source intentionally set up in an ambiguous or symmetrical way so that the the light could be interpretted as interchangeably coming from the track or the train. I'm gathering...
Okay. Erase my prior terminogy. I'll try to introduce as few of my own words as possible and borrow from the author's wording as much as possible in order to present my meaning. I'm supposing the author could have told the exact same story, but could have also included this alternate...
I think your comment is in line with the scenario that I'm trying to draw out, so I'm not catching your point. On the other hand, is it not true that the recipient's motion after the flash, does make a difference? Here's something from the author:
You and DaleSpam made similar comments regarding it not being a conclusion. I may not be communicating well, or may not be understanding some facet of the story. Somehow though, between post #27 and #28, DaleSpam seems to have connected to my thoughts. Would you mind reviewing those posts in...
Thanks for hanging in there with me. I see that you've given real effort into understanding where I'm coming from. I appreciate that.
You've highlighted what I see as the disconnect well.
I recently posted the description of the scenario that I've been thinking about. Typically, I think the two perspectives are taken to be from two different observers, in my case, I'm wondering why a single observer can't have two different perspectives on the situation.
In the above-posted...
