To draw oblique coordinates with the coordinates measured perpendicular to each axis would be wrong, right?
I saw it done in a fairly popular book. It's usually the case that I'm the one who is wrong, but I think the book is incorrectly treating minkowski diagrams. Look at these images from the text:
(It says a bit earlier in the text that the S' frame moves along x axis.)
It says events a and b are "coincident" (simultaneous?) in the S' frame but differ in time in S. However the diagram seems to show b, the event which is spatially further (along the motion), occur sooner in time than a, which is not what SR predicts right?
This is a quite popular book... (though I have not read but this chapter)
