In brief, the critical mass of a material is the amount needed for it to continue a nuclear reaction once it has begun.

Critical mass is also a sociodynamic term to describe the existence of sufficient momentum in a social system such that the momentum becomes self-sustaining and creates further growth.(wikipedia)
The term was taken and used to name mass cyclists in protest on roads.
ie, Critical Mass is a cycling event typically held on the last Friday of every month in over 300 cities around the world. The ride was originally founded in 1992 in San Francisco. The purpose of Critical Mass is not usually formalized beyond the direct action of meeting at a set location and time and traveling as a group through city or town streets on bikes.-(wikipedia.)
We have critical mass cycles in Western Australia from time to time.
I have re-used the term again to name and describe my work here:
