The following link is for the purpose of helping everyone see Einstein's papers for themselves, and the following information should help with the main points involved in the error. And again, everyone can look to see where the error exists.

The following url is a second part, and the first paper of June 30, 1905 is the starting point. You can click on "previous investigation" in the first sentence of this second paper to easily get back to the first paper, and then return to the second for the last part. This makes one url to copy and use here.

In the first paper this is where he starts proving relativity. The second paper is where he takes the foundational "assumption" of the synchronization is true and then uses relativity to get to E=mc^2. And, everything in the first paper also builds completely on the assumed truth of that synchronizing part. So, if the synch is wrong, then everything that follows is then wrong because it all relies completely on the synch being right.

In the first paper then, in I. Kinetic Part, and section 1. Definition of simultaneity, you can find the equation tB-tA = t'A-tB in the seventh paragragh. This stationary synchronizing is correct, and as described in my original post.

In section 2 On Relativity of Lengths and Times, you can read the entire section and in the latter part you will find the second equation mentioned in my post, and as follows.

tB-tA=rAB/c-v and t'A-tB=rAB/c+v

To make a long description short here, the last sentence in the paragragh where the second equation is located is completely wrong, and the error that Einstein made. You can obviously and should look for yourselves, but in any case it is fully wrong. The truth is that neither set of observers sees the clocks as synchronous and my original post calculations prove the fact of this.

You can look through all of the calculations and assumptions that follow the error point, but it is a huge waste of time in doing so because every last bit of the following ALL depends on the synch part being correct. And, all of the calculations are nothing but doing calcs on a wrong base.

In the second paper the first sentence and paragragh also link everything there to the first paper and assumes the first paper is also correct. It is not and then all of the second paper is then totally wrong in its conclusion. That conclusion is E=mc^2. NOTE that it is important to read the information in the yellow box at end, and where it describes Einstein using L instead of E, and the comment about the wording in italics. That is needed to understand the E=mc^2 connection.

So, this is provided so anyone can see the Einstein actual words and then see for yourself. The words were in German, but the translation is accurate.

Also, you can read everything on the papers, but you will save yourself a WHOLE lot of time and energy if you figure out soon in the first paper where the synchronization is wrong, and that everything after that point is fully linked and assuming the synch as being true. With THAT as fact, the remaining parts of the papers are true folly. And yes, I read the entire wording on both papers in the beginning. THAT was a HUGE waste of time. And yes, all of the calcs did look impressive and complicated, but the fact is still fact that it doesn't matter how impressive they look IF the foundationally required synch part is dead wrong. It is, and that makes all of the following calcs nothing but spit in the wind.
