Hello Mitch, live saving videos like always, but I gotta ask you for clarification in question d) of the example. So the reason why the pulse of light can travel from A to D in S is because it doesn’t time travel backwards + it is perpendicular to the ct=x line. For S’, I am assuming that the pulse (while being perpendicular) reaches/intersects a dotted line that brings you to the D point without going backwards in time? Does that mean the approach would be to try to do S frame first and then use the line you drew in the S frame to determine if its possible for S’?

Finally a video that explains how to find the order of events, thank you, you made it so clear!
Yay!
Thank you very much for your videos! Very helpful, especially since they are done for the IB's NEW physics syllabus.
Thank you, your videos saved my life!!!!
I'm so glad I could help!
did the video help explain bites the dust?
