In the early twentieth century, inspired by modern science such as Albert Einstein’s theory of relativity, an emerging avant-garde movement sought to expand the “dimensionality” of modern art, engaging with theoretical concepts of time and space to advance bold new forms of creative expression. Dimensionism: Modern Art in the Age of Einstein illuminates the remarkable connections between the scientific and artistic revolutions that shaped some of the most significant works of the time, from Alexander Calder’s kinetic sculptures to Marcel Duchamp’s early experiments with Conceptual art. Others were inspired by emerging research into interstellar and microscopic spaces, while expanding knowledge of quantum mechanics transformed many artists’ views of the world, leading to new approaches to understanding the nature of everyday reality.
