An amazingly well structured course taught with ‘tender loving care’ by an exceptional teacher!!!

The graph is plotted with x/t axes representing George’s/Earth’s reference frame. Instead can it be plotted using Gracie/Spaceship’s reference frame?

Awesome demonstration! Mr. Greene’s enthusiasm in teaching, his ability in simplifying troublesome concepts and also the quality of the animations used is truly top class! It’s unbelievable that this super high-quality content is available free!!
