Consider a human collective whose members issue opinions about an event that can only be true of false. Individual reliability is p, ranging between zero and one. It is higher

The Riemann hypothesis is an unproven statement referring to the zeros of the Riemann zeta function.

Mathematically, the motion of a fluid is described by the so-called Navier-Stokes equations. In the spirit of Newtonian mechanics, these equations should determine the future motion of the fluid out of its initial state.

The aim of this article is to highlight some previous challenges that were also a stimulus to finding proof for some interesting results. With this pretext, we present three moments in the history of mathematics that were important for the development of new lines of research.

The Hodge conjecture, proposed in 1950, is one of the seven millennium problems, and is framed within differential geometry and algebraic geometry.

The Russian mathematician Grigori Perelman did not accept the Fields Medal in 2006 and refused the million dollar prize for solving Poincaré's conjecture, one of the millennium problems, in 2010.

The Poincaré conjecture is a topological problem established in 1904 by the French mathematician Henri Poincaré. It characterises three-dimensional spheres in a very simple way. This problem was directly solved between 2002 and 2003 by Grigori Perelman, and as a consequence of his demonstration of the Thurston geometrisation conjecture.

The Clay Mathematics Institute made a list of seven problems in May 2000; they were called the «millennium problems». Finding their solution has an added incentive: each solver will receive a million dollars as a prize.

Genre Egalité et Mixité is a interdisciplinary research group on gender in education, created at the University of Lyon, that explores this issue along three axes: teacher training, scientific research, and the creation of a specialised library. Coming from several disciplines, its researchers have different profiles and consequently, different conceptions of feminism, making the team unique.

Women remained invisible in health sciences until the late twentieth century because they were not included in the cohorts used in researched studies. Thanks to the work done by different

We live in a rapidly transforming world. Social reality moves, nature moves, the cosmos moves and human beings move as well, but we do so not only across our biography

Cancer, one of the greatest problems of modern medicine, is also one of the most profound biological mysteries. And there are more than just one type of cancer: cancer has many different origins, development processes, and anatomic and pathological consequences.

Women make up the majority of the university students at the beginning, but are progressively overtaken by their male colleagues, until they become an invisible minority in the highest levels of the system.

Recent gender analyses have been opening new paths for innovation and excellence. They are the basis for the Gendered Innovations project. However, this work did not come out of nowhere; it is supported by decades of gender and science studies.  

The institutionalisation of equality policy in science should facilitate progress towards equality in a space that wants to consider itself merit (and ability) driven.

With the title of this monograph, SheScience, we want to delve on these two aspects. We are committed to science done by women in the same numbers and hierarchy as men, and to science that reveals differential characteristics between women and men, and those other aspects that are specific to women. Both often ignored.

The general model for evaluating scientific production fits into the accountability system: a way of measuring scientific output which does not usually acknowledge the presence of gender imbalances in academic

The existence of habitable extra solar planets, is nothing new in science fiction cinema. Perhaps more interesting is the existence of unusual planets, such as the planet Tatooine from Star Wars (1977), by George Lucas, that orbits a binary star system.
