If you increase the size of the disk in the non-linear example until it is almost linear (or the same size as the planet), then it is the same minus the possibility of General Relativities experimentally disproven time dilation (with muons), but the experiment works without time dilation, and would still experience the SR style of time dilation...
Actually that is an interesting point, since that is the same as an argument here: http://en.wikipedia.org/wiki/Time_dilation#Simple_inference_of_time_dilation_due_to_relative_velocity The difference is that here light is assumed to be C, and if we saw the clock on the rotating frame from the lab, or looked at the clock on the train from the ground it would only make sense if *time was seen to speed up in these rotating frames or train frames*! But even IF this time acceleration of the moving clock can be massaged into SR somehow, then we can complicate matters further by adding a second light source on the rotating frame that reverses the relationship... BUT now the speed of light can not possibly be C for the rotating frame as the clock would need to simultaneously be seen to tick faster and slower! And that is an easy conclusion to come to but I recommend not trying to imagine this as it will do your head in :) John On Fri, Feb 28, 2014 at 8:28 PM, H Veeder <hveeder...@gmail.com> wrote: > On second thought, I am not so sure about the "linear example". > I will need to see it illustrated to be sure. > > harry > > > > On Fri, Feb 28, 2014 at 2:14 AM, H Veeder <hveeder...@gmail.com> wrote: > >> The "linear example" you describe below. >> >> Harry >> >> >> >> On Fri, Feb 28, 2014 at 2:09 AM, John Berry <berry.joh...@gmail.com>wrote: >> >>> I very much appreciate your saying so Harry! >>> >>> You give me faith in humans! >>> >>> Which SR experiment are you saying I should illustrate? >>> >>> >>> On Fri, Feb 28, 2014 at 3:27 PM, H Veeder <hveeder...@gmail.com> wrote: >>> >>>> That is clearer.
