Many of us (at least those of us who are/were physics majors) have come across the infamous pole-and-barn problem when dealing with Special Relativity. It truly tests one's understanding of SR's time-dilation/length contraction effects, and forces us to examine how and when we know about something that occurs.
This paper revisits that pole-and-barn paradox and tries to convey a clear explanation of all the issues surrounding this problem. It might provide a clarification for those who might still have a bit of a problem with this scenario.
