He may have invented the Napier's Bones Napier's Rods Seeing there is nothing that is so troublesome to mathematical practice… than the multiplications, divisions, square and cubical extractions of great numbers, which besides the tedious expense of time are Archibald Napier was a justice-depute and was knighted in The definition of the logarithm follows: If his writings had survived he'd surely be considered one of the most brilliant and innovative geometers of antiquity.


At the Napier tercentenary celebrations. After Fibonacci, Europe still did not embrace the decimal system until the works of Vieta, Stevin, and Napier. On the surface of the thick rods are inscribed multiple numbers of digits, marked on the rod, as the digit of the rod is inscribed instead of letter a, doubled digit is inscribed instead of letter b and so on.

His theories of physics would seem quaint today, but he seems to have been the first to describe magnetism and static electricity.

Ptolemy perfected or, rather, complicated this model even further, introducing 'equants' to further fine-tune the orbital speeds; this model was the standard for 14 centuries.

Modern mathematicians refer to that "Theorem" as the Axiom of Archimedes. The reason for publishing the work is given by Napier in the dedication, where he says that so many of his friends, to whom he had shown the numbering rods, were so pleased with them that they were already becoming widely used, even beginning to be used in foreign countries one of these friends was Alexander Seton, the Earl of Dumfermline and High Chancellor of Scotland.

Leibniz wrote "He who understands Archimedes and Apollonius will admire less the achievements of the foremost men of later times. This problem was a major inspiration for Descartes and was finally fully solved by Newton. Cum Appendice de expeditissimo Multiplicationis promptuario. Continuing to add the digits along the diagonals and we will get the proper result He deliberately emphasized the beauty of pure, rather than applied, mathematics, saying his theorems were "worthy of acceptance for the sake of the demonstrations themselves.

At some point a longer list will become a List of Great Mathematicians rather than a List of Greatest Mathematicians. I've expanded my original List of Thirty to an even Hundred, but you may prefer to reduce it to a Top Seventy, Top Sixty, Top Fifty, Top Forty or Top Thirty list, or even Top Twenty, Top Fifteen or Top Ten List.
