On Aesthetics in Science

There have been, in recent years, exhibitions that juxtapose abstract paintings with photographs taken through the electron microscope, and contemporary sculpture with molecular models, in order to demonstrate the closeness of modern art and the products of modern science (or the effect of nature seeming to imitate art). And parallels between Cubism and relativity, or between action painting and the indeterminate character of quantum phenomena, have been put forward as evidence of a twentieth century mentality that is embodied in both art and science. The essays included in On Aesthetics in Science,however, deal with the subject at a much deeper level, beyond these somewhat facile likenesses and parallels. The book is not so much concerned with the products and artifacts of science as it is with the concepts, models, and theories that make them possible. And beyond that, it is concerned with the processesby which individual scientists-passing their ideas and data through Poincare''s irreducible "delicate sieve" of the aesthetic sensibility-create their concepts, models, and theories. Elegance, simplicity, economy, beauty, the sense of rightness, of inevitability, of perfect correspondence-these are the intuitive guides and formal goals that scientists have long recognized but have seldom explicitly articulated. Above all, the book treats aesthetics as a way of knowing, as fundamental to cognition. As the editor writes in her introduction, "The aesthetic factors in cognition-manifest in both art and science, though until recently more recognizable in art-are continuous, and broader than either.... Aesthetics is presented in this collection as a mode of cognition that focuses on forms and metaphors used in scientific conceptualizing and modeling.... Viewed as a way of knowing, aesthetics in science is concerned with the metaphorical and analogical relationship between reality and concepts, theories and models. As Cyril Smith points out, the search in science for models that illuminate nature seems to parallel certain crucial processes in art: they share a fundamental evocative quality." Aesthetic judgments in science are found to be as dependent on cultural context and personal style as they are in the arts. Thus, the book notes, although the "appreciation of elegance and economy is historically recurrent" and is certainly in accord with contemporary taste, whether conceptual or decorative, the Victorians "often preferred more complicated formulations" in their science. And while some individual scientists are guided by geometric intuitions that appeal to the visual cognitive mode (Kepler and the planetary orbits, Bohr and electron orbits), others are attracted to abstract mathematical formalisms (Newton and the universal laws of the cosmos, Heisenberg and "unvisualizable" particle of quantum mechanics). The book notes other such dualities that embody the dialectic of the scientific imagination. Just as art can be appreciated by those who did not engage in the process of its creation, so can the grandeur of the epoch-defining scientific theories. And in both cases an understanding of the appropriate aesthetics is recommended. That is why this book is for scientist and nonscientist alike-for all who would share the experience of the sudden eureka of discovery or the long evolution toward understanding. The book was developed from a course taught by the author at MIT.
