chain reaction

A series of events wherein the outcome of each instance specifically influences or causes the next. The phrase comes from the occurrence of such reactions in chemistry and physics. Deciding to take a course studying James Joyce in college set up a chain reaction that ultimately led me to move to Ireland. When one bookshelf fell, it caused a chain reaction that knocked over all the rest.

chain reaction

A series of events in which each influences or gives rise to the next event, as in If one person collects substantial damages by suing a company, you can expect a chain reaction of such lawsuits . The term originated in the physical sciences, first (1920s) chemistry and later (1940) physics; in the latter it denotes a process of nuclear fission. By the 1940s it had been transferred to more general use.
