A little about the video
Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay. A useful application of half-lives is radioactive dating.

By that we mean that whenever you have an equation that has to do with circles or spheres circumference, area, or volume the value pi is bound to figure into the equation somehow.
