Alain Connes (; born 1 April 1947 ) is a French mathematician, currently Professor at the Collège de France, IHÉS, The Ohio State University and Vanderbilt University.

It is named after André-Marie Ampère ( 1775 – 1836 ), French mathematician and physicist, considered the father of electrodynamics.

In 1842, the Italian mathematician Luigi Menabrea, whom Babbage had met while travelling in Italy, wrote a description of the engine in French.

André-Marie Ampère ( 20 January 1775 – 10 June 1836 ) was a French physicist and mathematician who is generally regarded as one of the main founders of the science of classical electromagnetism, which he referred to as " electrodynamics ".

In 1736, he participated in the expedition organized for that purpose by the French Academy of Sciences, led by the French mathematician Pierre Louis Maupertuis ( 1698 – 1759 ) to measure a degree of latitude.

Blaise Pascal (; 19 June 1623 – 19 August 1662 ), was a French mathematician, physicist, inventor, writer and Christian philosopher.

This phenomenon is known as Bourget's hypothesis after the nineteenth century French mathematician who studied Bessel functions.

Nevertheless, it was the French mathematician Pierre-Simon Laplace, who pioneered and popularised what is now called Bayesian probability.

French mathematician Étienne Bézout ( 1730 – 1783 ) proved this identity for polynomials.

However, this statement for integers can be found already in the work of another French mathematician, Claude Gaspard Bachet de Méziriac ( 1581 – 1638 ).

The French mathematician Augustin Louis Cauchy was the first to formulate such models in the 19th century, but research in the area continues today.

Cartesian means of or relating to the French philosopher and mathematician René Descartes — from his name — Rene Des-Cartes.

The adjective Cartesian refers to the French mathematician and philosopher René Descartes ( who used the name Cartesius in Latin ).

In 1752, the French astronomer Nicolas Louis de Lacaille subdivided it into Carina ( the keel, or the hull, of the ship ), Puppis ( the poop deck, or stern ), and Vela ( the sails ).

Antlia was created in 1756 by the French astronomer Abbé Nicolas Louis de Lacaille, who created fourteen constellations for the southern sky to fill some faint regions.

Then in 1702 the French astronomer Philippe de la Hire used a year he labeled at the end of years labeled ante Christum ( BC ), and immediately before years labeled post Christum ( AD ) on the mean motion pages in his Tabulæ Astronomicæ, thus adding the designation 0 to Kepler's Christi.

Finally, in 1740 the French astronomer Jacques Cassini, who is traditionally credited with the invention of year zero, completed the transition in his Tables astronomiques, simply labeling this year 0, which he placed at the end of Julian years labeled avant Jesus-Christ ( before Jesus Christ or BC ), and immediately before Julian years labeled après Jesus-Christ ( after Jesus Christ or AD ).

* 1918 – Gerard Henri de Vaucouleurs, French astronomer ( d. 1995 )

In 1794, this fortress was used by the French astronomer Pierre François André Méchain for observations relating to a survey stretching to Dunkirk that provided the official basis of the measurement of a metre.

The separation of Crux from Centaurus is generally attributed to the French astronomer Augustin Royer in 1679, but other historians attribute the invention of Crux to Petrus Plancius in 1613.

* 1704 – Louis Godin, French astronomer ( d. 1760 )

The gegenschein was first described by the French Jesuit astronomer and professor Esprit Pézenas ( 1692 – 1776 ) in 1730.

It was first detected as an unknown yellow spectral line signature in sunlight during a solar eclipse in 1868 by French astronomer Jules Janssen.

The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India.
