'''The Sand Reckoner''' (Greek: Ψαμμίτης, Psammites) is a work by [[Archimedes]] in which he set out to determine an upper bound for the number of grains of sand that fit into the [[universe]].

== Description ==

In order to do this, he had to estimate the size of the universe according to the contemporary model, and invent a way to talk about extremely large numbers.

The work, also known in Latin as ''Archimedis Syracusani Arenarius & Dimensio Circuli'', which is about 8 pages long in translation, is addressed to the Syracusan king [[Gelo II]] (son of [[Hiero II]]), and is probably the most accessible work of Archimedes.

In some sense, it is the first [[research-expository paper]].
