I'm not sure what this has to do with my reply to your original post. You stated:

I was answering the question of who produced a device that measured seconds... and it's in the Wikipedia article. Before then, records indicate that "seconds" were actually "heartbeats." That's not a terribly accurate measurement, since everyone's varies but it might give some approximation. And, of course, depending on when you measure that heartbeat you would get a different number. So sometimes you could measure a falling object and it would be five heartbeats before it hit the ground or six or seven or four or any other number.

In the case of 6/pi, I doubt they could accurately measure something that fell during a time period that might last only one and a fraction heartbeats.

...unless you have some evidence of Egyptian chronometers that I'm not familar with? The ones I know of are water clocks and candles and daylight and solar markers like sundials...and heartbeats. I admit my knowledge isn't all encompassing. I'd like to see links to a more detailed time measuring device if such exists.

No, thanks. I could come up with the same measure using all sorts of interesting mathematics (calculus, for instance... vector analysis...) that the Egyptians didn't have.

But your original question asked:
------------

Yes... not in the same measurements, but we all know that gravity works and I'm pretty sure that folks here know about the variations in speed depending on whether the measurement is taken at sea level or higher and depending on slight gravitational anomalies in the region.

Again, to answer your question, it may have been the Germans who invented a standardized second in 1560 or thereabouts, but the first fairly accurate one was done after 1657 and Christain Hugyens is credited with the invention:
[en.wikipedia.org]

Gallileo, by the way, timed the fall (roll down an incline, actually) of objects by starting and stopping a stream of water and weighing the water (the following site includes a translation of Gallileo's description of his experiment and how he timed it.)
[galileoandeinstein.physics.virginia.edu]

So, to answer your question (still) it appears the second wasn't measured and standardized until 1657. If they'd been doing it earlier, the Greeks would have picked it up from the Egyptians.


(I do admit my brain was off on a distracted note with the stellar measurements. My bad!)
