Visualizing Math and Physics with Python

Former Gr@v member Raimon Luna developed a project to visualize many mathematical and physical concepts through images and animations fully generated by short Python scripts. 

Each picture is supposed to introduce a different idea in mathematics or physics in a visually appealing way, without the use of any text or numbers. For those of us who tend to have a visual understanding of these abstract topics, including the author, the pictures can be a nice way to get a different intuition on them.

Our understanding of the cosmos is shaped by what we are able to observe in the sky. Resolving progressively smaller astrophysical structures requires instruments with increasingly high angular resolution. However, even an ideal telescope is limited by nature through diffraction, which ties its resolving power to the diameter of its collecting aperture.

Tracing Curvature: Where Art Meets Science

On January 20th, 2026, the art–science exhibition was officially (re)opened at Fábrica - Centro Ciência Viva de Aveiro. The event was hosted by Fábrica’s director, Pedro Pombo, and brought together the head of the Department of Mathematics, Alexandre Almeida, and the director of CIDMA, Delfim Torres, along with several colleagues. This initiative is another step in sharing the beauty of science with a broader audience, strengthening the connection between scientific research and society.

10 years of SPRG and GW observations

The 10th anniversary of the Portuguese Society of Relativity and Gravitation (SPRG), along with the anniversary of the first gravitational wave (GW) detection, was celebrated with a specially made cake at the XVIII Black Holes Workshop.

Dyson, just before the first detection of Gravitational Waves (GWs) by LIGO, raised the question of whether the detection of a single graviton can be achieved with GW strain detectors. If this is possible, then it would be a direct evidence for the quantization of the gravitational field.

Quasi-integrability in classical field theories

We present a general inverse scattering formalism for systems with quasi-zero curvature representations, extending the tools of integrable models to the quasi-integrable setting.
