  • I came here with the same question but now I realize that if I ask it I will only get replies explaining me what Z-score is and not Z-score of what. So I will just assume it is sth akin to h-index. Still does not make much sense to me as to why average h-index papers “don’t survive” (i.e get rejected because no one is interested lets say) where as negative ones do.




















  • In order to keep you rotating at a fixed distance to the center, the wheel has to apply a central force to you to keep changing your velocity direction (which if left unperturbed would be tangent to the wheel and you fly off in a fixed direction like someone yeeted you). That is what will kill you.

    On the other hand if you apply any time dependent coordinate transformation which has acceleration (i.e double t derivative non zero) you will inevitably change forces in your equations so that becomes your new universe.
