This chapter explores the intrinsic connection between mathematics and art through Mathemalchemy, a collaborative traveling installation created by a team of 24 mathematical artists and artistic mathematicians known as “Mathemalchemists.” The work brings to life a richly imagined world where mathematical ideas are made tangible through artistic media. This chapter focuses on five fundamental themes shared by both disciplines – ideal forms, symmetry, infinity, abstraction, and recursion – and highlights how they appear throughout the installation. Together, these elements demonstrate that mathematics and art are not opposing domains but, in many senses, one and the same. Mathemalchemy invites viewers to inhabit a world where proof and play coexist, where aesthetic intuition and logical structure are intertwined, and where the creative process itself becomes a living expression of mathematics as art.
