What is the equation for half lives?

Mathematically, the half life can be written in terms of the decay rate: Half-life = – ln(2) / k. The natural logarithm (ln) is a mathematical function that is the inverse to the exponential (e) function. You can find the natural logarithm on a scientific calculator where it will be labelled “ln.”.

What is the half life story?

Main article: Half-Life storyline. The original Half-Life takes place at the Black Mesa Research Facility in 200-. During an experiment, researchers at Black Mesa accidentally cause a Resonance Cascade which rips open a portal to Xen , a parallel universe, and the only known borderworld.
