Animath turns 25

On March 16 this year, the Animath association celebrated its 25th anniversary at the Institut Henri-Poincaré.

The centenary of Gustave Eiffel's death

Mathematics and literature,

Gilles Cohen has always championed breaking down the divide between literary and scientific backgrounds. To him, the two are not only perfectly compatible but also mutually enriching.

Tête-à-tête chercheuse(s),

Nathalie Ayi, a researcher and associate professor at Sorbonne Université, also created and hosts the podcast Tête-à-tête chercheuse(s).

An adventure in fifteen videos

Directors Cassia Sakarovitch and Gwenael Mulsant have set themselves a challenge: to make short videos about mathematical concepts from the specialist mathematics curriculum in the final two years of French high school.

A theorem puzzle in pictures every Monday

Since 2015, the Image des maths website (https://images.math.cnrs.fr) has featured a "picture-theorem puzzle" every Monday, taken from Geometry in Figures, a book published in 2011 by the young Russian mathematician Arseniy Akopyan (CreateSpace Independent Publishing Platform) and available in French as Figures sans paroles (Independently Published, 2019).

Pitot's theorem

First stated by the French engineer and physicist Henri Pitot (1695–1771), the theorem that bears his name concerns quadrilaterals with an inscribed circle (known as tangential quadrilaterals).

New careers in mathematics and computer science

The exhibition "Mathematics, Computer Science… With Women!" is available. Created by the association Femmes et Mathématiques in partnership with the CCSTI of the Centre-Val de Loire region, it comprises twenty-one roll-up panels presenting the career paths of twenty young women. Each panel features a portrait by photographer Marie-Pierre Dieterlé.

An essential issue

Présence d’Évariste Galois 1811–1832 (APMEP, 1982) is a special issue devoted entirely to the young algebraist, marking the 150th anniversary of his death.

The "treasure hunters"

Alongside university and academic research, enthusiasts conduct genuine investigations into Galois's life

Editorial

Évariste Galois is one of the best-known mathematicians—and also one of the least understood.

My first differential equation

Do differential equations frighten you? Admittedly, there is good reason to be wary. Yet they become very approachable once a few constraints are imposed; linearity is one of them. And when the factors involved are constants, they are within everyone's reach—especially when the right-hand side is zero.
