René Descartes ( 31 March 1596 – 11 February 1650) was a French philosopher, mathematician and scientist who spent most of his life in the Dutch Republic.<br/><br/> He has been dubbed the father of modern philosophy, and much subsequent Western philosophy is a response to his writings, which are studied closely to this day. In particular, his <i>Meditations on First Philosophy</i> continues to be a standard text at most university philosophy departments. Descartes' influence in mathematics is equally apparent; the Cartesian coordinate system — allowing reference to a point in space as a set of numbers, and allowing algebraic equations to be expressed as geometric shapes in a two-dimensional coordinate system (and conversely, shapes to be described as equations) — was named after him.<br/><br/> He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the scientific revolution and has been described as an example of genius.

The Comoros, officially the Union of the Comoros, is a sovereign archipelago island nation in the Indian Ocean located at the northern end of the Mozambique Channel off the eastern coast of Africa between northeastern Mozambique and northwestern Madagascar.<br/><br/> Other countries near the Comoros are Tanzania to the northwest and the Seychelles to the northeast. Its capital is Moroni, on Grande Comore.

John Calvin, born Jehan Cauvin: 10 July 1509 – 27 May 1564) was an influential French theologian and pastor during the Protestant Reformation. He was a principal figure in the development of the system of Christian theology later called Calvinism, aspects of which include the doctrines of predestination and of the absolute sovereignty of God in salvation of the human soul from death and eternal damnation.<br/><br/> Various Congregational, Reformed, and Presbyterian churches, which look to Calvin as the chief expositor of their beliefs, have spread throughout the world.
