SUMMARY
The discussion centers on the measurement of half-lives and average lifetimes in nuclear physics, specifically regarding the definition of a year. It highlights that there is no universally accepted convention for the equivalent of a year in seconds within the field. The most cited response indicates that the numerical error in values expressed in years is often larger than the discrepancies caused by different definitions of a year, such as the Julian year (365.25 days) versus the Gregorian year. Notably, the half-life of carbon-14 has an uncertainty exceeding 0.5%, further emphasizing the lack of precision in these measurements.
