Abstract:
Athanasius Kircher paid special attention to magnetism, more specifically terrestrial one, in his work Magnes sive de arte magnetica. Other Jesuits of his time, such as Garzoni and Cabeo, also wrote on this subject. Kircher studied in particular magnetic declination and its possible use to determine geographical longitudes. At his time, this was an important subject for long sea journeys. First, he collected a large number of observations of magnetic declination from different sources in three tables and two lists with a total of 518 values, among them forty-three made by Jesuits. Kircher prop

Abstract:
AbstractIn the early nineteenth century, Norwegian mathematician and astronomer Christopher Hansteen (1784–1873) contributed significantly to international collaboration in the study of terrestrial magnetism. In particular, Hansteen was influential in the origin and orientation of the magnetic lobby in Britain, a campaign which resulted in a global network of fixed geomagnetic observatories. In retrospect, however, his contribution was diminished, because his four-pole theory inUntersuchungen der Magnetismus der Erde(1819) was ultimately refuted by Carl Friedrich Gauss inAllgemeine Theorie des

Abstract:
Charts marked with the lines of magnetic variation have been published since Halley's Atlantic chart of 1701. It was already known that the location of the magnetic poles shifted over time, and that the north and south poles were not diametrically opposite. As more seafarers penetrated the Southern Ocean, isogons on the charts were extended southwards with greater confidence. At sea variation was measured by comparing compass direction with the Sun's midday shadow. In polar regions, where horizontal force is too weak to attract a compass needle, the location of the pole was sought by observing

AbstractWe evaluate a numerical model on the thermal evolution of terrestrial planets to estimate life-time of planetary intrinsic magnetic field for various mass planets. In this model, we take into account the pressure-dependency of density profile of the planet by using Birch-Murnaghun equation of state, and simulate thermal evolution of the planet by means of mixing length theory. According to our numerical results, the planetary mass must be between 0.1 and 1.4 Earth mass to sustain the intrinsic magnetic field for 4.5Gyr. If existence of intrinsic magnetic field were a key factor to make

Abstract:
Abstract After their restoration of 1814, the Jesuits made significant contributions to the natural sciences, especially in the fields of astronomy, meteorology, seismology, terrestrial magnetism, mathematics, and biology. This narrative provides a history of the Jesuit institutions in which these discoveries were made, many of which were established in countries that previously had no scientific institutions whatsoever, thus generating a scientific and educational legacy that endures to this day. The essay also focuses on the teaching and research that took place at Jesuit universities and se

Abstract:
ABSTRACT Geophysics, in the modern sense, started with geomagnetic works in the 1600s in the Ottoman Empire. The period between 1600 and 1800 included the measurement of magnetic declination, inclination and magnetic field strength. Before that time, there was only a little information available, such as how to use a compass, for example in the Kitab-i Bahriye (the Book of Navigation) by Piri Reis, one of the most important mariners of the Ottoman Empire. However, this may not mean that magnetic declination was generally understood. The first Turkish scientific book relating to terrestrial mag
