이상현상

내가 흔하거나 평범하지 않은 "이상 현상"들에 관심을 갖는 이유는 다음과 같다.

Anomalous values in experimental results may indicate either a problem with the experiment or a new phenomenon to be

investigated.  <from 'Introduction to Data Mining' by 'Tan et al.'>

다음은 Kuhn(1962)의 조언이다.

Discovery commences with the awareness of anomaly. . . . It then continues with a more of less extended exploration of the area of anomaly. And it closes when the paradigm theory has been adjusted so that the anomalous has become the expected. 

<from Kuhn, T. S. (1962). The structure of scientific revolution, University of Chicago Press, Chicago.>
