1. Absolute dating (chronometric or calendar dating ) - -process of determining a specific date for an archaeological site or artifact Radiometric dating - technique used to date materials based on knowledge of the decay rates of naturally occurring isotopes, and the current abundances.

2. The half-life of a quantity subject to exponential decay is the time required for the quantity to decay to half of its initial value.

3. Let N(t) be the amount of an element left (after decay) at time t. tN(t) 0 N0N0N0N0 1 N 0 *(1/2) 2 N 0 *(1/2) 2 3 N 0 *(1/2) 3 4 N 0 *(1/2) 4

4. We calculated the amount of a quantity N(t) left after any period of time t to be N(t) = N 0 (1/2) t where N 0 is the initial amount of the quantity.

5. N(t) = N 0 (1/2) t What happens to the amount of the quantity as t gets larger and larger? N(t) = N 0 (1/2) t the quantity decays exponentially as t gets larger and larger

6. How does an exponential function compare with a linear function? Do they grow at similar rates? Which grows faster? 2x2x 2*x 2x2x
