And you have to check to make sure he touches the edge at the end of each lap.
Without these observations you cannot be sure that the time is valid.
Without the starting time it is Actually, knowing the starting time is still not enough.
During the race you have to watch the swimmer and count how many laps he has swum so you know that he has done 1,500 metres.
Geochronologists do not claim that radiometric dating is foolproof (no scientific method is), but it does work reliably for most samples.
My thanks to both him and other critics for motivating me.
Much of the Earth's geology consists of successional layers of different rock types, piled one on top of another.
That is why you need at least two, sometimes three judges to measure the time of the race to the standard needed to enter the record books.
It would make no difference how accurate or high-tech the wristwatch was.
But they omit discussion of the basic flaw in the method: you cannot measure the age of a rock using radioactive dating because you were not present to measure the radioactive elements when the rock formed and you did not monitor the way those elements changed over its entire geological history.
