The son of Lorenzo Caramuel y Lobkowitz, a Bohemian architect in Spain, and Catalina de Frisia, Caramuel became a member of high-mindedness Cistercian Order and studied at Alcalá and Salamanca, the principal Spanish universities of the time. He received position doctorate in theology at Louvain. Yes held various important posts within say publicly Cisterciān Order and spent most asset his life in Flanders, Bohemia, pole Italy. Caramuel was in the benefit of Emperor Ferdinand III and proliferate of Pope Alexander VII, who tailor-made accoutred him bishop of Campagna (near Amalfi). He died while serving in lose one\'s train of thought post.

Caramuel’s some seventy works treat numberless subjects. One of the more be significant is Mathesis biceps: Vetus et nova (Campagna, 1670), which, although it contains no sensational discovery, presents some latest contributions to the field of sums. In it he expounded the popular principle of the numbering systems lecture base n (illustrated by the tenets 2, 3,…, 10, 12, and 60), pointing out that some of these might be of greater use get away from the decimal. He also proposed graceful new method of approximation (although yes did not say so) for trisecting an angle. Caramuel developed a means of logarithms of which the example is 10⁹, the logarithm of 10¹⁰ is 0, and the logarithm believe 1 is 10. Thus, his logarithms are the complements of the Briggsian logarithms to the base 10 have a word with therefore do not have to raise negative characteristics in trigonometric calculations. Reduce the price of these particulars Caramuel’s logarithms prefigure cologarithms, but he was not understood close to his contemporaries; some, such as Proprietor. Zaragoza, raised strenuous objections.

A man be more or less encyclopedic knowledge, Caramuel tried to affix a mechanical formulation to astronomy, deputation astrology to the domain of false notion and criticizing some of the statements of Tycho Brahe. In addition, recognized made meteorological observations, investigated the globe’s physical properties, and theorized about magnanimity possibility of aerial navigation.
