Vega-Bremiker
For a long time one of the most important table works for technology and science was the Vega-Bremiker , published by the Weidmann bookstore .
The underlying seven-figure logarithms were around 1795 by the Slovenian mathematician and imperial officer Jurij Vega (better known as Georg Freiherr von Vega calculated) and presented to about 1970, the most widely used in Europe logarithmic calculation aid high accuracy. It is only in the 1970s, it was the slow the emerging electronic pocket calculator .
Vega recognized the advantage of seven-digit tables in the fact that they represent an ideal compromise between high calculation accuracy and interpolating between the table values that is not yet too tedious . Since the mathematician was also very familiar with arithmetic practice as a teacher and engineer, he selected the table interval (for the trigonometric functions 1 " or 10") in such a way that the result was a high level of effectiveness - in the exchange relationship between simple / cumbersome looking up and lengthy / fast interpolation.
In addition, the panels were made in a bookbinding style with a very durable cover that fits comfortably in the hand and z. B. in the course of studies at technical universities or in the practice of geodetic calculations ensured years or decades of usability. The large number of well-preserved copies in the second-hand bookshops attests to these advantages of the work.
The original title of the edition 1797 is logarithmic - trigonometric tables , along with other established for use of mathematics tables and formulas and even appeared in two volumes. The most frequently used editions 75–100 as "Vega Bremiker " (from 1856 and most recently several times between 1940 and approx. 1965, also reprints ) combined both volumes in a single, but very solidly bound table work about 4 cm thick. Printing on light, rough paper was an added benefit for users.
