	From circa 1972, a Quiz on Qualitative Physics for u/g students of mechanics devised by HAC. This was the start of active research, which involved the development of dragons - simple qualitative puzzles in elementary physics -- that both the expert and the tyro could answer with confidence, but with remarkably different solutions. See the web page Dragons.

My MIT Artificial Intelligence Laboratory Memo

H.A. Cohen, The Art of Snaring Dragons, M.I.T. Artificial Intelligence Laboratory Memo Number 338, May 1975. Dragons are formidable problems. challenging, and yet solvable using little or even no algebra or calculus. Dragons are also distinguished by the fact that (unlike other physics problems seen by the tyro as "difficult") both the tyro - and the experienced physicist, are confident with their - so-different - predictions. Thus such Dragons are akin to the Conservation Puzzles of Piaget, where both the four-year old pre-conserver, and the six year conserver are equally confident with their (differing!) conclusions. In this paper, written when the writer was part of the LOGO Group at the MIT Artificial Intelligence Laboratory, an explanation is given in terms of the Frames concept of Marvin Minsky.
