Throughout history many of the Roman Catholic clerics have made contributions to science, mostly during periods of Church domination of public life. These cleric-scientists include Nicolaus Copernicus, Gregor Mendel, Georges Lemaître, Albertus Magnus, Roger Bacon, Pierre Gassendi, Roger Joseph Boscovich, Marin Mersenne, Bernard Bolzano, Francesco Maria Grimaldi, Nicole Oresme, Jean Buridan, Robert Grosseteste, Christopher Clavius, Nicolas Steno, Athanasius Kircher, Giovanni Battista Riccioli, William of Ockham, and others. The Catholic Church has also produced many lay scientists and mathematicians, including 20th century Nobel Laureates like chemist Mario J. Molina, chemist John Polanyi, physicist Riccardo Giacconi, among many others. The Jesuits have made numerous significant contributions to the development of science. For example, the Jesuits have dedicated significant study to earthquakes, and seismology has been described as "the Jesuit science". The Jesuits have been described as "the single most important contributor to experimental physics in the seventeenth century". According to Jonathan Wright in his book "God's Soldiers", by the eighteenth century the Jesuits had "contributed to the development of pendulum clocks, pantographs, barometers, reflecting telescopes and microscopes, to scientific fields as various as magnetism, optics and electricity. They observed, in some cases before anyone else, the colored bands on Jupiter's surface, the Andromeda nebula and Saturn's rings. They theorized about the circulation of the blood (independently of Harvey), the theoretical possibility of flight, the way the moon affected the tides, and the wave-like nature of light." Protestantism had an important influence on science. According to the Merton Thesis there was a positive correlation between the rise of Puritanism and Protestant Pietism on the one hand and early experimental science on the other. The Merton Thesis has two separate parts: Firstly, it presents a theory that science changes due to an accumulation of observations and improvement in experimental techniques and methodology; secondly, it puts forward the argument that the popularity of science in 17th-century England and the religious demography of the Royal Society (English scientists of that time were predominantly Puritans or other Protestants) can be explained by a correlation between Protestantism and the scientific values. In his theory, Robert K. Merton focused on English Puritanism and German Pietism as having been responsible for the development of the scientific revolution of the 17th and 18th centuries.
