**Logic Euler Diagram**- in a logical setting one can use model theoretic semantics to interpret euler diagrams within a universe of discourse in the ex les below the euler diagram depicts that the sets animal and mineral are disjoint since the corresponding curves are disjoint and also that the set four legs is a subset of the set of animals the original application of euler diagrams as a way of diagrammatically demonstrating logic is widely used in schools where they are a great aid to teaching set theory more academic work includes hammer ham95 who introduced a sound and plete logical system based on euler diagrams p div div class sa uc ul class b vlist li class b annooverride div class b factrow a href https cs kent ac uk events conf 2004 euler programme html h id serp 5431 1 programme a 183 a href https cs kent ac uk events conf 2004 euler submissions html h id serp 5432 1 submissions a 183 a href https cs kent.
