22.8 Clocks in Motion: Examples

office hours

I see how asynchronous clocks justify each team’s claim of a longer length for an object at rest in their frame. But what if Team Platform tosses Team Train a ruler to measure the train's length? Now explain Team Train's claim of a longer length.

In the example you gave in class, George and Germaine disagree regarding which firecracker went off first. So, is it true that for any two events, some observers will think one happened first while some will claim the other happened first?
