Bürgi was born in 1552 Lichtensteig, Toggenburg, at the time a subject territory of the Abbey of St. Gall (now part of the canton of St. Gallen, Switzerland).Not much is known about his life or education before his employment as astronomer and clockmaker at the court of William IV in Kassel in 1579; it has been theorized that he acquired his mathematical knowledge at Strasbourg, among others ...
The Swiss mathematician Jost Bürgi constructed a table of progressions which can be considered a table of antilogarithms [25] independently of John Napier, whose publication (1614) was known by the time Bürgi published at the behest of Johannes Kepler. We know that Bürgi had some way of simplifying calculations around 1588, but most likely ...
In mathematics, the logarithm to base b is the inverse function of exponentiation with base b.That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x.
Included are function tables of logarithms (a useful computational tool that had been described in 1614 by John Napier) and antilogarithms, and instructive examples for computing planetary positions. [7] For most stars these tables were accurate to within one arc minute, [8] and included corrective factors for atmospheric refraction. [9]
With John Pell he computed the first table of antilogarithms in the 1630s. [13] John Aubrey, relying on Pell's testimony, states that Warner had claimed to have anticipated William Harvey's discovery of the circulation of the blood, and that Harvey must have heard of it through a Mr Prothero. Pell also mentioned that Warner had been born ...
MK-36. Elektronika B3-36 (Russian: Электроника Б3-36), renamed to Elektronika MK-36 later in the production, is a soviet calculator.It was produced since 1979. It is able to perform four arithmetic operations: calculating natural and decimal logarithms, antilogarithms, direct and inverse trigonometric functions, reciprocals, factorial, perform calculations with two-level brackets ...
The primary calculation in GRAPE hardware is a summation of the forces between a particular star and every other star in the simulation. Several versions (GRAPE-1, GRAPE-3 and GRAPE-5) use the logarithmic number system (LNS) in the pipeline to calculate the approximate force between two stars and take the antilogarithms of the x, y and z components before adding them to their corresponding ...
