They were able to do so because they shared two essential characteristics. Their achievement was sufficiently unprecedented to attract an enduring group of adherents away from competing modes of scientific activity. Simultaneously, it was sufficiently open-ended to leave all sorts of problems for the redefined group of practitioners to resolve. Achievements that share these two characteristics I shall henceforth refer to as “paradigms,” a term that relates closely to “normal science.” — The Structure of Scientific Revolutions -- part contents for background part 22 ----- text ----- • WHOLE EARTH • LEARNING • INQUIRY • Philosophy -- part contents for background part 23 ----- text ----- 06051114 -- part contents for background part 30 ----- text ----- card id 73409 -- part contents for background part 31 ----- text ----- card id 65127 -- part contents for background part 32 ----- text ----- stack "WHOLE EARTH" stack "LEARNING" card id 44534 card id 45655 -- part contents for background part 27 ----- text ----- card id 45655 -- part contents for background part 28 ----- text ----- card id 312592 -- part contents for background part 29 ----- text ----- card id 85791
