António Ribeiro Gomes, a retired full professor at the Coimbra Mathematics Department, passed away at the end of June.

Born in 1930, he completed his PhD in 1964, after studying in Paris with Yvonne Choquet-Bruhat, one of the world's foremost experts on General Relativity and Gravitational Radiation.
In the 1970s and 80s he played a decisive role in the organization of CMUC, with special impact on the fields of Mathematical Physics, Geometry, Analysis and Probability & Statistics.
He held leading positions in the Coimbra Mathematics Department and in the School of Science and Technology, as well as in the National Institute for Scientific Research (INIC), then the main funding agency for research in Portugal.

New postdocs at CMUC

Portugal at the 2017 International Mathematical Olympiad

The team representing Portugal at the 2017 International Mathematical Olympiad has been selected. The team members are Duarte Nascimento, Henrique Navas, Kevin Pucci, Manuel Cabral, Maria Matilde Silva and Pedro Fernandes.
The competition will take place in Rio de Janeiro, Brazil, between 12 and 23 July. The Portuguese team will depart a few days early to participate in problem sessions with the Brazilian team at IMPA.
Selection and training of Portuguese teams in all international mathematical competitions is part of the activities of "Project Delfos", a Mathematics school for highly motivated young students. Delfos is a 15-year old Coimbra Mathematics Department initiative and is supported by CMUC.

Summer University 2017

The Summer University 2017, promoted by the University of Coimbra (UC), will take place from 16 to 21 July. This is an event for high school students. Throughout the event, several high school students will have the opportunity to participate in scientific, pedagogic and cultural activities that will show them what is best done in the UC and in the town. The Department of Mathematics and CMUC collaborate with a set of activities on Mathematics, as well as in some transversal activities.

More Atractor's webpages in English

The webpage of Atractor (Interactive Mathematics) has now English versions of the following pages:

Around the wheel
Comparing two geometric problems
Journey into PI
Math without words
Mathematical training of lifeguards
Morley Theorem
The curvature and torsion: how to distinguish the shape of a curve
The dynamics of a trick
The loxodrome
Triangles with multiple angles

These translations of the original Portuguese version are part of a project involving a team of CMUC and DMat, whose goal is the full translation into English of the mathematical contents of Atractor's website.

3D film "The math of seashells"

Atractor has produced a 3D film about the mathematical description of seashells growth. The film illustrates how the great majority of shells existing in nature can be generated by a fixed set of equations by simply varying some parameters. This gives one more example of how the apparent complexity one sees in nature may have a much simpler mathematical inner structure.
The film is based on Atractor's webpage about the mathematical description of seashells.

See the 2D version of the film in the Atractor's YouTube channel.
