It seems a contradiction but it is not. A MAthematicAl ApproAch to Art The history of the relationships between art and mathematics is a long and winding road. There was an increased interest in these relationships over the last two centuries, and Max Bill wrote intriguing words on this subject in his 1949 ar- ticle “The Mathematical Way of Thinking in the Visual Art of Our Time,” on the relationship between art, form and mathematics. He wrote about mathematics as the science of transformations, relations and connections. Bill wanted to point out that, while mathematical and artistic activity are obviously not interchangeable, the mathematical laws of space and of the relations between objects can and should be of great importance for art. Bill used words very similar to those mathematicians used. A real and clear definition of the way in which the relationships between the two disci- plines—considered by many to be so distant—should be is as follows: It must not be supposed that an art based on the principles of mathematics, such as I have just adumbrated, is in any sense the same thing as a plastic or pictorial interpreta- tion of the latter. Indeed, it employs virtually none of the resources implicit in the term “pure mathematics.” The art in question can, perhaps, best be defined as the building up of significant patterns from the ever-changing relations, rhythms and proportions of abstract forms, each one of which, having its own causality, is tantamount to a law unto itself. As such, it presents some analogy to mathematics itself [5]. [Previously:] By a mathematical approach to art it is hardly necessary to say I do not mean any fanciful ideas for turning out art by some ingenious system of ready reckon- ing with the aid of mathematical formulas. So far as com- position is concerned every former school of art can be said to have had a more or less mathematical basis. There are also many trends in modern art which rely on the same sort of empirical calculations. These, together with the artist’s own individual scales of value, are just part of the ordinary elementary principles of design for establishing the proper relationship between component volumes; that is to say for imparting harmony to the whole [6].
