0 the smallest amount of matter that is needed to produce a nuclear chain reaction
1 the size or number that something needs to reach before a particular change or development can happen:
A minimum critical mass of primary care staff committed to research is needed to drive an evaluation forward.
This subset is the critical mass needed to begin any collective action.
These functional relations will show that there exists a critical mass ratio, below which the synchronization regime extends to infinity.
The great technical problem of such a system is the critical mass of a fission chain reaction, making it difficult to miniaturize a fission explosion.
It enlarges the critical mass and opens possibilities for sharing facilities.
These investigators speculated that a critical mass of scar tissue provided the substrate for ventricular arrhythmias.
It would certainly lack the critical mass which is essential for progress.
There is a critical mass for blow-up and a rich set of dynamics including families of similarity solutions for finite-time blow-up and infinite-time spreading.
