In philosophy, a supertask is a countably infinite sequence of operations that occur sequentially within a finite interval of time.[1] Supertasks are called hypertasks when the number of operations becomes uncountably infinite. A hypertask that includes one task for each ordinal number is called an ultratask.[2] 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.[3]
