Pierre de Fermat, Pascal's famous contemporary | Tangente
Who was Pierre de Fermat? Pascal regarded him as the greatest mathematician of his time. He was a very modest man, probably aware of his extraordinary mathematical abilities, who readily shared his often original ideas. We know that he was a man of great learning, capable of translating works from Latin and Greek and writing sophisticated poetry, even… in Spanish.

A master of mathematical induction
Mathematical induction is a major tool in mathematical proofs. On at least three occasions, Pascal explicitly uses reasoning that is "almost" mathematical induction, making him one of the method's inventors.

Pascal and geometry: the mystic hexagram | Tangente
Blaise Pascal's earliest work in geometry has passed into legend. He was only 16 when he published his Essay pour les coniques (Essay on Conics) in 1640.

An extraordinary mind — The life of Pascal | Tangente
Blaise Pascal was no universal scholar, but he developed a rigorous, experiment-based scientific method that enabled him to transcend the prevailing orthodoxy and open up new avenues in both mathematics and physics.

Pascal on stage — Descartes and Pascal on stage | Tangente
The mathematician is also one of the central characters in a philosophical comedy by Jean-Claude Brisville (1922–2014), best known to the general public for Le Souper (1989), featuring Talleyrand and Fouché, whose film adaptation was a memorable success.

Pascal's 400th anniversary in Clermont | Tangente
In Auvergne, the city of Clermont-Ferrand, Clermont Auvergne Métropole and the University of Clermont Auvergne (UCA), together with their many partners, are preparing to celebrate the 400th anniversary of Blaise Pascal's birth in 2023.

Sidon sets
Number theory is a branch of mathematics that still contains questions that are easy to state yet remain unsolved. Sidon sets, in which the differences between pairs of terms are all distinct, are a case in point.

Numbers at the heart of mathematics—and our lives | Tangente
The Mathematics Forum held at UNESCO last November took stock of the role of mathematics in our societies, students' attainment—which, according to various international comparative studies, is plummeting—and the place of women in mathematics.

Happy New Year! The properties of 2023
As is now customary, the Tangente team explores the properties of the year number in our Gregorian calendar. What can we say about 2023? We will examine it in particular through the Josephus sieve.
