Foremost among the earliest mathematicians on record is(c.625 - c.550 BC). However, in a poem about Thales, the famous librarian/Callimaque(c.300-240 BC) seems to credits an Phrygian mathematician,by the name of , with the straightedge-and-compass constructionof the circle circumbscribed to a scalene triangle.

Ancient Indians held the art of reckoning () in the highest esteem. They used symbols for marks or divisions () which are theancestors of modern digits (1, 2, 3, 4, 5, 6, 7, 8, 9). The introduction of a tenth symbol for (0) pavedthe way to our of decimal numeration...

Yet, a Swiss watchmaker by the name of(1552-1632) had the same idea in 1588(six years before Napier) but did not publish until 1620 (six years after Napier). [His first name is variously spelled: Jobst, Jost, Joost, Joose, or Joobst.] Prior to that, Bürgi was one of the foremost pioneers of the so-called method which reduces a multiplication to the computation ofa sum, a difference and a half-sum with 4 lookups of available trigonometric tables. In its purest form, requires only a table of cosines and yields a product as the average of thecosines of a sum and a difference by applying the following formula (which Bürgi brought to the attention of who used it very extensively for many years):

Although this makes a difference only when the utmost in precision is called for,the Fahrenheit and the Celsius scales are nolonger defined in terms of actual measurements of the ice point or the steam point. Instead, both scales now refer to the thermodynamic temperature scale, in which 273.16 K is the exact temperatureof the (the only temperature at whichall three states of water can be observed at once).

The Slovanian mathematician Jurij Vega (1754-1802)published his first table of logarithms in 1783. He endeavored to build 7-figure log tables,based on the original Vlacq tables. These were checked by soldiers who received a gold ducat for every mistake they found... Vega's first edition of appearedin 1794; the 90th edition [!] was published in 1924...
