Martin Gardner's Wonderland

In France, Martin Gardner is best known for his mathematical recreations written as a science communicator. He who, strangely, never studied mathematics at university, but was a magician, philosopher, writer and publisher, left a much vaster work resulting from his multiple interests. Thus, new facets are discovered through his very original philosophical development of scientific skepticism or through his amazing and prolific literary production ranging from science fiction to poetry, including novels. And one will not fail to be amazed by exploring his mathemagic tricks.

Structuring mathematics

The multiplication of mathematical discoveries leads, at the end of the 19th century, to the need for a structuration that involves questioning the foundations. The many paradoxes constructed within the framework of old theoretical systems lead to rethinking the definitions of various concepts previously perceived intuitively, such as infinity, sets, numbers… The work of Euclid having opened the way to an axiomatic approach, this is systematized throughout the 19th and 20th centuries with the work of Cantor, Hilbert, Peano, Russell, Gödel among many others. This approach is made possible by the formalization of logic, which results in the automatic processing of reasonings, opening the way to modern computer science.

Yvonne Choquet-Bruhat, a mathematician of relativity

Yvonne Choquet-Bruhat, who died on 11 February 2025, is known as the first woman to become a member of the Académie des sciences. Dwelling on this fact risks overshadowing the importance of her work. Her colleague Piotr Chruściel takes us through her research, which is little known to the general public.
