Dearest Clockologists,

They say ' A stopped clock tells the correct time twice a day '


Well, here's a stopped clock !


[attachment=15703]

A Clock That Has Stopped Sometime Last Week !



Considering that time is a flowing kind of time thing that keeps moving forward...And to be really pedantic about the whole thing....can the clock ,which has stopped,  really truly tell the right time twice a day ?...After all..it is not  "with time"  ie:...it is stopped and even when a working clock reaches that time wouldn't time itself have to stop at the exact same indication for the stopped clock to be correct ?


whajafink ?

That's a very good question. Our normal view of time is that it's a sort of "flowy" thing, but we can only really measure time by counting things that "tick". At the finest level of granularity we count off subatomic "ticks". Problem is, when we get down to really small scales (at the quantum level) we can't count events at all. I'm not even sure we can sense a direction of time at that level.

This is probably a slightly wonky explanation, but I'm sure I will get lambasted someone will correct any errors I may have made.
There ain'ta no sanity clause, and there ain'ta no centrifugal force ćther.

It is correct at just the point where it stops being a bit fast, but before it's a bit slow.

Well, in that case, even the most accurate atomic clock is never correct.
But if you forget any smaller division in time than the "second", that sheepy clock will be correct twice a day

If we are going to be really pedantic, then this clock would only be right once a day!

A stopped clock can really be correct twice a day, but the problem is you do not when that time is correct.

Or, to be slightly more pedantic, it's right a little over 24 times a day- but in different time zones.
