) is the time required for a quantity to reduce to half its initial value.
Note the consequence of the law of large numbers: with more atoms, the overall decay is more regular and more predictable.
A half-life usually describes the decay of discrete entities, such as radioactive atoms.
Carbon-14 dating can be used on objects ranging from a few hundred years old to 50,000 years old.
Note that after one half-life there are not exactly one-half of the atoms remaining, only approximately, because of the random variation in the process.
Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic unit for the exponential decay equation.
The accompanying table shows the reduction of a quantity as a function of the number of half-lives elapsed.
But on the second day, there is no reason to expect that one-quarter of the puddle will remain; in fact, it will probably be much less than that.
This is an example where the half-life reduces as time goes on.
