Does a clock’s second hand try to move non-stop around the clock, but it’s somehow stalled so it takes one second to get past each niche?
Or does it stop at each niche, and move to the next one after stopping at each niche for one second?
The question for the first one is what stalls the second hand over each line?
The problem with the second one is that it takes time to move from one point to another, and the second hand couldn’t just travel instantaneously to the next line. For it to work, some parts of the time the second the hand stopped at the niche would have to be equally divided on either side of the second, to give the second hand time to get to the next line. Is that what happens?
Or does it incorporate both, and take half a second to get to the next line, and half a second to pause on each line?
And in all of those, when and/or where does one second stop and the next begin? And what makes the second hand hesitate, wherever it hesitates?
