When a parameter, N, say, decays at a rate proportional to how much of it there is at a given time, we can write that $$N=N_0e^{-\lambda t}$$ where $$N_0$$ is the value of N at time t = 0 and $$\lambda$$ is the decay rate.  The half-life, $$\tau$$, is related to $$\lambda$$ by $$\tau =\frac{ln2}{\lambda}$$.

 

However, this might make more sense if you post a specific half-life question!

zegroes.....The way to work out half-life problems is just to ignore them for the first half of your life........this still leaves you with another half-life to figure them out.....
