We take a very large particle accelerator of several kilometers. On this particle accelerator, we fix a point A, coordinates (0,0,0) and we ask to draw the trajectory of the proton in R. We assume z=0. We then have a large circle. We then request a change of reference frame, and we request the trajectory of point A in the proton reference frame. I wish good luck to whoever answers, it's not high school level. R.H.
