Total and mathematics: high-performance computing
HPC, or high-performance computing, harnesses multiple processing units, such as CPUs (central processing units) and GPUs (graphics processing units used for computation), to carry out computationally intensive tasks. The Total group has always been a pioneer in the field.
The mathematics of 5G | Tangente
Large companies are beginning to understand that they cannot survive in the long term without funding fundamental research. A career as a mathematician in the private sector is therefore possible, provided you have some understanding of technological challenges.
Modélisation des écoulements d'air autour des éoliennes : équations de Navier-Stokes et simulations numériques
The energy sector needs advanced mathematical expertise. In wind energy, modeling airflow means grappling with the formidable Navier–Stokes equations. Numerical simulation draws on a variety of discretization techniques.
Images: unexpected applications | Tangente
When we think of the mathematics behind image processing, compression, transmission, denoising and the restoration of digital files naturally come to mind. Its other applications are less familiar—for example, its use in art to help restore frescoes.
Taking to the skies with mathematics
An aircraft is an extraordinarily complex system. Have you ever considered how much mathematics goes into making your flight possible—and enjoyable? Come aboard! Let's take a quick look at the specific demands of aeronautics.
Randomness in video games
ChickenPods is a free-to-play video game (F2P to those in the know) developed in 2019 at the startup Mathilde. Randomness plays an important role in generating environments and determining how the chickens move. That is where mathematics comes in...
Blockchain in all its mathematical forms | Tangente
Blockchain technology is among the technologies to watch in the years ahead, as it could revolutionize several sectors of the economy. It draws on recent mathematical developments through increasingly sophisticated processes.
Matrices and graphs in accounting
Accountants are not known for using sophisticated mathematical tools. Yet modern techniques enable them to handle many situations arising in what is known as "complex accounting".

Jeanne Calment: the mathematics of longevity | Tangente
Jeanne Calment of France, who died in 1997 at the exceptional age of 122, long held the title of the world's oldest person. In January, Nicolaï Zak, a Russian mathematician with an interest in genealogy, and gerontologist Valeri Novosselov claimed that Jeanne had in fact died back in 1934 and been "replaced" by her daughter Yvonne… because of an inheritance-tax matter.
