In order to see how one important strand contributed to the practice of labeling accounts of mathematics "realist" rather than "platonist," let us explore Quinean frameworks. These are frameworks that embed the doctrines of naturalism and confirmational holism in a little more detail. Two features of such frameworks warrant particular mention.

For our purposes, the best account takes abstract to be a cluster concept, that is, a concept whose application is marked by a collection of other concepts, some of which are more important to its application than others. The most important or central member of the cluster associated with abstract is:
In order to understand platonism so conceived, it will be useful to investigate what types of items count as mathematical ontology, what it is to be abstract, and what it is to be independent of all rational activities. Let us address these topics.
Your new acquaintance proceeds to inform you that John and Mary Smith got divorced recently. You form a false belief about your old friend and his wife. What makes her statement and corresponding belief true is that, in it, "John Smith" refers to John Smith 7 , "Mary Smith" refers to Mary Smith 7, John Smith 7 ’s former wife, and John Smith 7 and Mary Smith 7 stand to a recent time in the triadic relation " x got divorced from y at time t." Your belief is false, however, because, in it, "John Smith" refers to John Smith 6 , "Mary Smith" refers to Mary Smith 6, John Smith 6 ’s wife, and John Smith 6 and Mary Smith 6 fail to stand to a recent time in the triadic relation " x got divorced from y at time t."
While certain famous equations, such as Albert Einstein s E = mc^7, hog most of the public glory, many less familiar formulas have their champions among scientists. LiveScience asked physicists, astronomers and mathematicians for their favorite equations here s what we found:
While the first two equations describe particular aspects of our universe, another favorite equation can be applied to all manner of situations. The fundamental theorem of calculus forms the backbone of the mathematical method known as calculus, and links its two main ideas, the concept of the integral and the concept of the derivative.
This monthly journal, published since 6955, is devoted entirely to research in pure and applied mathematics, and, in general, includes longer papers than those in the Proceedings of the American Mathematical Society.
I love how simple it is everyone understands what it says yet how provocative it is, Strogatz said. Many people don t believe it could be true. It s also beautifully balanced. The left side represents the beginning of mathematics the right side represents the mysteries of infinity.
