Algorithmic techniques of various kinds are almost universally used in mathematical physics. These are frequently supplemented, in the case of fundamental physics, by a few of the elementary techniques of formal logic. In most cases, the semiotic aspect of the subject is not considered explicitly. This may be justifiable in principle if one has arrived at a short set of mathematical axioms from which the results of the theory under consideration may be deduced mathematically in a direct manner, though any interpretations of terms and connectives left without semantic comment until such axioms are obtained are in general likely to be unrewarding from the point of view of a directional semantic discussion of physical concepts. For instance, typical summaries of the lattice-theoretic approach to quantum mechanics assume that the sign ' =' means 'implies'. Reference to the literature of formal logic gives a large number of different ways 'implication' may be mathematically formalised (Curry, 1957), none of them (of course) entirely satisfactory as formalisations of the U-language term. There is no immediate reason why the term 'implication' should be forced into the description of a physically complex theory like quantum mechanics. One can quote Kleene (1962); '"Implication" is a handy name for '~ '. In using it, we follow the practice common in mathematics of employing the same designation for analogous notions arising in related technical theories. An example is the many different kinds of "addition" and "multiplication" in mathematics'. The easiest way out is to regard 'implies' as a label for' ~' and to endow that label with a U-language significance whenever one feels inclined to do so. However, if semiotic problems are ignored in this way, there are problems involved if one wishes to deduce a set of mechanical rules which will allow the axioms of a theory to be deduced from given experimental data. As well as the obvious difficulty that it is hard to define connectives properly if one does not know what they are intended to mean in the U-language, there is also the diff that until the metasemiosis problem has been considered a primitive frame with a clear U-language significance is unlikely to be obtained. In particular, since connectives 'v', '^', and '~' appear to be basic connectors in many schemes of deduction, they may also arise as adjunctors in the axioms ifa distinction (Curry, 1957) is not made between
