TiYBoM Introduction.

From "I Love Music and I Love Science-- Why Would I Want to Mix the Two?" (the Introduction) of This is Your Brain on Music by Daniel J. Levitin:

The Oxford historian Martin Kemp points out a similarity between artists and scientists.  Most artists describe their work as experiments"n concern or to establish a viewpoint.  My good friend and colleague William Forde Thompson (a music cognition scientist and composer at the University of Toronto) adds that the work of both scientists and  artists involves similar stages of development: a creative and exploratory "brainstorming" stage, followed by testing and refining stages that typically involve the application of set procedures, but are often informed by additional creative problem-solving.  Artists' studios and scientists' laboratories share similarities as well, with a large number of projects going at once, in various stages of completion.... What artists and scientists have in common in the ability to live in an open-ended state of interpretation and reinterpretation of the products of our work.  The work of artists and scientists is ultimately the pursuit of truth, but members of both camps understand that truth in its very nature is contextual and changeable, dependent on point of view, and that today's truths become tomorrow's disproven hypotheses or forgotten objets d'art.... For the artist, the goal of the painting or musical composition is not to convey literal truth, but an aspect of a universal truth that if successful, will continue to move and to touch people, even as contexts, societies, and cultures change.  For the scientist, the goal of a theory is to convey "truth for now"-- to replace an old truth, while accepting that someday this theory, too, will be replaced by a new "truth," because that is the way science advances.

... I just figured out how it actually might be possible for the biochemist and the scenic designer to live happily ever after.  More importantly, this explains Ross and Rachel.
