Par Collective Queerality

Migrating can mean many different things for each person. For some, it is a dream, a door to new opportunities. For others, it is a necessity: an imposed decision that is beyond their control. Regardless of the reasons why we migrate, changing our country of residence is a disorienting experience. Navigating a new system, with new laws, customs, and languages, is fascinating but also confusing, exhausting, and complex: like moving through a maze. La complexité des laberynthes thus invites us to compare both experiences: to explain in a tangible way how we cope with, for example, healing a broken heart far from “home.”
La complexité des labyrinthes is part of the 2023 program of the Bureau Des Questions Importantes, which took place from September 1st to 16th in Nyon, Switzerland.

I helped with some of the drawings on the following website, where the University of Heidelberg is announcing the celebration of the Poincaré conjecture as part of the Millennium Problems MathFest.

Some surfaces may look different, but they are topologically equivalent. That is, we can smoothly deform one (without pinching or breaking it) into the other.

One way to study the structure of the objects surrounding us is by looking at their symmetries. To find out more about wallpaper tilings, their symmetry groups, and their presence in the Palace of Alhambra, check out the January blog post of STRUCTURES, by clicking here.
