Scientific contributions

Apart from being a monarch, the King's interests included mathematics, and anything that would be beneficial to his warlike purposes. He is credited with having invented an octal numeral system, as well as a more elaborate one with the base 64, which he considered more suitable for war purposes because all the boxes used for materials such as gunpowder were cubic. According to a report by contemporary scientist Emanuel Swedenborg, the King had sketched a model of his thoughts on a piece of paper and handed it to him at their meeting in Lund in 1716. The paper was reportedly still in existence a hundred years later but has since been lost.
