What is "supertask"

n. (context philosophy English) A quantifiably infinite number of operations that occur sequentially within a finite interval of time.

In philosophy, a supertask is a countably infinite sequence of operations that occur sequentially within a finite interval of time. Supertasks are called "hypertasks" when the number of operations becomes uncountably infinite. The term supertask was coined by the philosopher James F. Thomson, who devised Thomson's lamp. The term hypertask derives from Clark and Read in their paper of that name.
