1. critical mass
   In physics, the minimum amount of fissionable material required to sustain a chain reaction. Of a software product, describes a condition of the software such that fixing one bug introduces one plus epsilon bugs. (This malady has many causes: creeping featurism, ports to too many disparate environ...

6. critical mass
   Critical mass is the minimum mass of a fissionable material (235U or 239Pu) that will initiate an uncontrolled chain reaction as in an atomic bomb. The critical mass of pure 239Pu is about 4.5 kg, and of 235U about 15 kg.
