The Spacetime Interval and Causality | Special Relativity

[@FacultyofKhan]

In anticipation of this video, I have fully braced myself for the controversy that will inevitably arise from my choice of the signs on the delta terms in s^2. For those of you who choose to put -1 in front of your spatial coordinates, come at me!

That's me. It seems more intuitive when reasoning about timelike, spacelike. and null because t is ct and your comparing distances; also for many calculations.

Looking forward to the video on 4-vectors!

You read my mind, because that's up next in this series!
