En general un campo es un campo vectorial. En el cual siempre hay ciertamente un dualismo implícito que la física ha heredado de las matemáticas. Albert Lautman en Mathematics, ideas and the physical real lo expuso con toda claridad:
- «The geometrical interpretation of the theory of differential equations clearly places in evidence two absolutely distinct realities: there is the field of directions and the topological accidents which may suddenly crop up in it, as for example the existence of . . . singular points to which no direction has been attached; and there are the integral curves with the form they take on in the vicinity of the singularities of the field of directions . . . The existence and distribution of singularities are notions relative to the field of vectors defined by the differential equation. The form of the integral curves is relative to the solution of this equation. The two problems are assuredly complementary, since the nature of the singularities of the field is defined by the form of the curves in their vicinity. But it is no less true that the field of vectors on one hand and the integral curves on the other are two essentially distinct mathematical realities.»
