An observation made by the inertial observer is the act of assigning to any event the coordinates x, y, z of the location of its occurrence, and the time read by the clock at (x, y, z) when the event occurred.
It is not the time t on the wrist watch worn by a scientist located at (0, 0, 0) when he first learns of the event.
A visual observation is of this second type: the eye regards as simultaneous all events it sees at the same time; an inertial observer regards as simultaneous all events that occur at the same time as recorded by the clock nearest them when the events occurred.

We will never mean a visual observation unless we say so ... (查看原文)
