Measurement of N, the number of 14 C atoms currently in the sample, allows the calculation of t, the age of the sample, using the equation above. The above calculations make several assumptions, such as that the level of 14 C in the atmosphere has remained constant over time. The calculations involve several steps and include an intermediate value called the "radiocarbon age", which is the age in "radiocarbon years" of the sample: Radiocarbon ages are still calculated using this half-life, and are known as "Conventional Radiocarbon Age".

September 18, Iraidka Shutterstock Though people have always understood the concept of nothing or having nothing, the concept of zero is relatively new; it fully developed in India around the fifth century A. Before then, mathematicians struggled to perform the simplest arithmetic calculations.
