The work of Julia Carrillo (Mexico, 1987) develops around the balance between art and science, in an attempt to analyze reality. Her degree in mathematics led her to combine scientific methodologies with artistic practices to represent natural phenomena, such as the movement of light and the shapes of water. Among the works proposed in this monograph we find “Coreografías”: a series of 24 rayographies that make up a dance where light, striking translucent geometric objects, unfolds and bounces. The variation of the projection angle of the light simulates the different incidences of the sun on the earth during the day. The change of angle of the light generates new visions, so simple geometric structures positioned on the photo-sensitive paper come to life giving life to a sort of “choreography”. In “Superficies minimas”, using the analogue photographic lens, Carrillo shows the results of spatial studies based on structures generated by soap bubbles. It starts from the mathematical concept that deals with the “stable form”, in this case membranes that are able to contain the greatest volume within a film with the smallest possible surface. The sphere is the simplest minimum surface and can be observed in a soap bubble. The artist shows us, with splendid black and white images, that when a conglomeration of bubbles is created, they lose their sphericity and their geometry changes, always keeping the largest volume inside and ensuring that the soap film (or the surface) covers the minimum area. In the “Score” polyptych we find water which, like a lens, continuously modifies the reflection of light and traces an imaginary coastline through the union of the eight frames that compose it. With the medium of painting, the artist investigates concepts such as the border and the infinite. On display some works on paper test the possible geometric configurations based on two elements: line and color. In these works we find the contamination between various geometries, as in optical devices, generating three-dimensional illusions.
