Confusing mathematical masturbation with intercourse between research and reality

Summary:
Confusing mathematical masturbation with intercourse between research and reality No real problem worth solving can be solved without some basic research. Therefore the engagement of faculty and students on real problems yields basic research problems whose solutions are of practical significance. Furthermore, the validity of these solutions can be tested in the most effective way known: in application. This avoids one’s confusing mathematical masturbation with intercourse between research and reality. Russell L. Ackoff [h/t Robert Locke]
