"Research can be driven by a quest for fundamental understanding with no prospect for use (Bohr's quadrant), for individual, group, or societal use without regard for fundamental knowledge (Edison's quadrant), or fundamental knowledge inspired by use (Pasteur's quadrant). (Research may also be done with neither use nor fundamental knowledge in mind, e.g., lab training.) In the post-war era, he argues, Pasteur's quadrant - knowledge for use - has been the source of the most significant scientific advances."
