The Sand Reckoner (Greek: Ψαμμίτης, Psammites) is a work by Archimedes, an Ancient Greek mathematician of the 3rd century BC, in which he set out to determine an upper bound for the number of grains of sand that fit into the universe. In order to do this, Archimedes had to estimate the size of the universe according to the contemporary ...
Following the heliocentric ideas of Aristarcus (but not explicitly supporting them), around 250 BCE Archimedes in his work The Sand Reckoner computes the diameter of the universe centered around the Sun to be about 10 14 stadia (in modern units, about 2 light years, 18.93 × 10 12 km, 11.76 × 10 12 mi). [40] In Archimedes' own words:
Part 1 is mainly concerned with expressing large numbers, Georg Cantor and infinity, and the imaginary unit.After disparaging the Roman numeral system for being limited to thousands (M), The Sand Reckoner system of myriads and octades is described.
[21] [22] In the Sand-Reckoner, Archimedes gives his father's name as Phidias, an astronomer about whom nothing else is known. [22] [23] A biography of Archimedes was written by his friend Heracleides, but this work has been lost, leaving the details of his life obscure.
The polymath Archimedes (ca. 287–212 BC) invented a decimal positional system based on 10 8 in his Sand Reckoner; [2] 19th century German mathematician Carl Gauss lamented how science might have progressed had Archimedes only made the leap to something akin to the modern decimal system. [3]
Following the heliocentric ideas of Aristarcus (but not explicitly supporting them), around 250 BC Archimedes in his work The Sand Reckoner computes the diameter of the universe centered around the Sun to be about 10 × 10 14 stadia (in modern units, about 2 light years, 18.93 × 10 12 km, 11.76 × 10 12 mi). [29] In Archimedes' own words:
One of the earliest examples of this is The Sand Reckoner, in which Archimedes gave a system for naming large numbers. To do this, he called the numbers up to a myriad myriad (10 8) "first numbers" and called 10 8 itself the "unit of the second numbers".
