theory). Other notable priest scientists have included Albertus Magnus, Robert Grosseteste, Nicholas Steno, Francesco Grimaldi, Giambattista Riccioli, Roger Boscovich, and Athanasius Kircher. Even more numerous are Catholic laity involved in science:Henri Becquerel who discovered radioactivity; Galvani, Volta, Ampere, Marconi, pioneers in electricity and telecommunications; Lavoisier, "father of modern chemistry"; Vesalius, founder of modern human anatomy; and Cauchy, one of the mathematicians who laid the rigorous foundations of calculus. 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. Jesuit in science 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 18th 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." Protestant 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
