I understand a lazy shisnos example alright. I am still not clear why peculiarities about the speed of light must mean time and length must also change.
If light causes us to perceive weird stuff does this mean that weird stuff is really happening? If we see wave lengths of light as red...
I am still finding this hard. If it is agreed the A events are one and the same then the only thing left to discuss is what each observer experiences.
I am not getting it.
You guys appear to be saying the A events happen at a different time. If so the whole thought experiment seems to be a...

Thanks. It seems I was not understanding what Einstein was saying and getting confused by what is meant by the invariance of the speed of light.
I will have to think about the text but it seems to be sorted out.
Cheers

>>So you agree that the flashes of light are not simultaneous from the point of view of the train observer? What's the problem, then?
Einstein appears to be saying the reason for the flash not being simultaneous for the train observer is because he is moving towards the light rays coming from B...
This is going to be easier if you just stick with einsteins text.
Are you saying the timing of the two events on the embankment are not directly related to the timing of the two events on the train where both events are known as A and B?
So I am asking you how are you interpreting his...
I am not sure what you are wanting to say to me.
Einstein tells us the train observer does not see simultaneity because he is moving towards the light rays coming from B.

Einstein says "
Lightning has struck the rails on our railway embankment at two places A
and B far
distant from each other. I make the additional assertion that these two lightning flashes

Each observer is correct in what he observes. Only one correctly detects reality using his vision. One observer does not see a simultaneous flash. However on the moving object there were two simultaneous flashes. We can explain to the observer on the moving platform why he has not seen...
I realize the observers do not both see simultaneous flashes. The issue i am raising is why it matters? how does einstein then leap from observer experience to time itself having changed? Sure the two observers might be confused but we can see the cause of their confusion, ie one observer...
Hi, I read through einsteins popular book on relativity translated into english around 1922 and subsequently read the original 1905 paper on the electrodynamics of moving bodies.
So we have a fixed observer seeing flashes happening at the same time and we have a moving observer seeing one...
Are you telling me it is impossible to explain in words why energy is released when a chemical bond is formed? I thought maths was a shorthand way of describing something that could in principle be described in words?
Hi, I am wondering about latent heat release when water freezes but it seems best to start with a regular exothermic reaction. How does bond formation create heat? What is actually happening at the microscopic level so that these combining particles are capable of causing adjacent molecules...
