Discipline is a subdivision of knowledge. — Wikipedia
Academic discipline or academic field is a subdivision of knowledge that is taught and researched at the college or university level. Disciplines are defined (in part) and recognized by the academic journals in which research is published, and the learned societies and academic departments or faculties within colleges and universities to which their practitioners belong. Individuals associated with academic disciplines are commonly referred to as experts or specialists.
While academic disciplines in and of themselves are more or less focused practices, scholarly approaches such as multidisciplinarity/interdisciplinarity, transdisciplinarity, and cross-disciplinarity integrate aspects from multiple academic disciplines, therefore addressing any problems that may arise from narrow concentration within specialized fields of study. — Wikipedia
Science would be ruined if (like sports) it were to put competition above everything else, and if it were to clarify the rules of competition by withdrawing entirely into narrowly defined specialties. The rare scholars who are nomads-by-choice are essential to the intellectual welfare of the settled disciplines. — Benoit Mandelbrot
Interdisciplinarity involves the combination of two or more academic disciplines into one activity (e.g., a research project). It is about creating something by thinking across disciplinary boundaries. — Wikipedia
