Radiometric dating disproved
He claimed that it was capable of dating animal, plant and human remains of fairly recent origin. As they say on Star Trek, we are all carbon based units.Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.You could talk about the tiny quartz crystal and the piezoelectric effect used to provide a stable time base for the electronic movement.You could describe the atomic workings of the quartz oscillator and how it resonates at a specific and highly stable frequency, and how this is used to accurately pace a timekeeping mechanism.
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.
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.
If you check this educational page by the US Geological Society you will see that they spend all their time talking about the technicalities of radioactive decay.
This illustrates the whole problem with the radioactive dating of geological events.
Those who promote the reliability of the method spend a lot of time impressing you with the details of radioactive decay, half-lives, mass-spectroscopes, etc.
