Many scientists are uncomfortable with the idea that even their most precise procedures originate more from intuitive leaps of the imagination than from explicitly describable method. Yet even that most exact branch of the sciences, mathematics, depends largely upon intuition for its great advances. The solving of difficult equations, the detection of hitherto unsuspected mathematical pattern, realization that stars, planets and subatomic particles follow mathematical rules are all triumph of intuition. Similarly in biology the discovery of the rules of genetic inheritance and the blueprint of its mechanism, the causes of infectious diseases and the nature of immune reaction of the human body against them, are all successes ascribable initially to intuition. It is perfectly true that these discoveries would not have been accepted as established had not intuition been followed by strict mathematical proof or by experimental verification, but this should not be allowed to obscure the fact that such proof or verification is secondary to intuition.
Intuition leads to asking relevant questions.
Inquiry, experiment and rigorous mathematical proof are concerned with answering those questions. Many of you use and even more heard the term intuition. Intuition is the apprehension of a situation or object by sense of intellect without the conscious use of any reasoning process. This is the most common form of assessment used by human beings when they judge the problems and conditions. Indeed in most circumstances there is not time to use any other form of mental process.
