  Cartesian coordinate system - Wikipedia, the free encyclopedia
Cartesian means relating to the French mathematician and philosopher Descartes, who, among other things, worked to merge algebra and Euclidean geometry.
The modern Cartesian coordinate system in two dimensions (also called a rectangular coordinate system) is commonly defined by two axes, at right angles to each other, forming a plane (an xy-plane).
In analytic geometry the Cartesian coordinate system is the foundation for the algebraic manipulation of geometrical shapes.

 Cartesian closed category - Wikipedia, the free encyclopedia
The category of all directed graphs is cartesian closed; this is a functor category as explained under functor category.
In algebraic topology, cartesian closed categories are particularly easy to work with, and it is regrettable that neither the category of topological spaces with continuous maps nor the category of smooth manifolds with smooth maps is cartesian closed.
Certain cartesian closed categories, the topoi, have been proposed as a general setting for mathematics, instead of traditional set theory.

 One World, Two Maps (thoughts on the Wikipedia debate). Many-to-Many:   (Site not responding. Last check: 2007-11-07)
Cartesian people assume that any technological change lands you somewhere — reality is just one point of many on the map, and is not especially privileged over other states you could be in.
Cartesian people want to know, for any change, where you end up, and what the characteristics of the new landscape are.
When they make mistakes, Cartesian people tend to underestimate the cost in moving from reality to some imagined alternate state, and to overestimate their ability to predict what a global maximum would look like.

 Cartesian product - Wikipedia, the free encyclopedia
In mathematics, the Cartesian product (or direct product) of two sets X and Y, denoted X × Y, is the set of all possible ordered pairs whose first component is a member of X and whose second component is a member of Y.
The Cartesian product is named after René Descartes whose formulation of analytic geometry gave rise to this concept.
The assertion that the Cartesian product of a non-empty collection of non-empty sets is non-empty is equivalent to the axiom of choice.

 20th WCP: Cartesian Dualism and the Union of Mind and Body: A Synchronic Interpretation
Thought and matter are clear and distinct primitive notions that come from reason, whose role is laying the foundations for Cartesian metaphysics and physics, while the primitive notion of union is acquired by the senses and lacks clarity and distinction even while it serves the objective of founding Descartes' moral philosophy.
Cottinghams Cartesian trialism emerges from the difficulty to regard sensation and imagination as purely mental faculties, due to the fact that they involve the activity of a hybrid unit.
Bentez argues that while thought and extension are the notions which found the Cartesian metaphysics and physics, the union of mind and body appears as the fundamental notion upon which Descartes builds his moral or practical philosophy.

 Robert Desgabets
Although Desgabets himself was not one to adopt Cartesianism in its entirety, in his view his own criticisms perfected and maintained the integrity of the Cartesian principles, while Cordemoy's adoption of atoms and the void was a direct affront to the Cartesian metaphysics.
Desgabets defends the Cartesian doctrines of sensible qualities, matter, mind-body dualism, mind-body union and interaction in man while criticizing Descartes's argument for the cogito as the first principle of knowledge, the claim that there is such a process as pure intellection, that there are innate ideas, and that ideas have objective reality (pure possibility).
In his favour, he never strayed from the Cartesian metaphysics, i.e., its substance dualism of mind and matter, substance-mode ontology, mind-body union and interaction, and the view that extension is the essence of matter and thought the essence of mind; and he remained loyal to the Cartesian physics against that of the atomists.

 cartesian-theory
The Cartesian structure of space imposes a physical law that all mechanical systems have three degrees of freedom, which explains the shape of a house, a car, an airplane; it is the first principle of all zoological formation and axiomatically predetermines the anatomy of man. The human body is a three-axis Cartesian structure (Fig.
This Cartesian geometry of mitosis and embryology then is the origin of the Cartesian symmetry of the brain, evidenced in the intersection of the neuraxis, the Medial fissure, and the Central (Rolandic) fissures of the brain- the three Cartesian axes of the brain.
While the Cartesian theory indicates simply lateralization of the limbic system for N, it now explains the "novel" identification of cortical arousal with E. the Bell-Magendie dichotomy is most visible in the cortex (the motor-sensory strip) which would lead to an identification of E with cortical function.

 Solipsism and the Problem of Other Minds [Internet Encyclopedia of Philosophy]
This Cartesian view of the matter was, in its essentials, accepted by John Locke, the father of modern British empiricism.
The point which we come to then, in essence, is this: assuming the validity of the Cartesian position, we have to infer that it makes as much or a little sense, on these premises, to attribute any psychological predicate to another human being as it does to attribute it to a table or a rock.
The Cartesian egocentric view of the mind and of mental events which gives rise both to the spectre of solipsism and attempts to evade it by means of the argument from analogy has its origins in this very misapprehension.

 Adventures in Science and Technology - Cartesian Divers Project   (Site not responding. Last check: 2007-11-07)
Air can be compressed much more easily than water, therefore the air inside the Cartesian diver becomes more dense than the water as we push on the sides of the bottle.
Due to the increase in the relative density of the Cartesian diver, the diver sinks to the bottom of the bottle.
It is one of Galileo's students, Raffaelo Maggiotti, who first described the Cartesian diver in writing (he called it the Cartesian Devil).

 A Philosophical Toy
In contrast to its hesitant appearance in the history of science, the Cartesian diver is nearly ubiquitous in science teaching.
The other demonstration is puzzling precisely because a test tube in a bottle appears to reverse the behavior of the Cartesian diver An inverted test tube containing an amount of air insufficient to keep it floating is dropped into a 1.5 liter plastic soft drink bottle.
Students reach a level of tentative certainty in their knowledge of the Cartesian diver, unsettled with the idea that it may not be possible to find the book where the final truth is written but invigorated with the accomplishment of having thoroughly investigated a compelling physical system.

The more direct followers of Descartes, the Cartesian philosophers, devoted themselves chiefly to the problem of the relation of body and soul, of matter and mind.
In physical theory his doctrines were formulated as a compromise between his devotion to Roman Catholicism and his commitment to the scientific method, which met opposition in the church officials of the day.
Mathematics was his greatest interest; building upon the work of others, he originated the Cartesian coordinates and Cartesian curves; he is often said to be the founder of analytical geometry.

 Dictionary of Philosophy of Mind - skepticism, Cartesian   (Site not responding. Last check: 2007-11-07)
skepticism, Cartesian - Any of a class of skeptical views against empirical knowledge based on the claim that claims to empirical knowledge are defeated by the possibility that we might be deceived insofar as we might be, for example, dreaming, hallucinating, deceived by demons, or brains in vats.
This kind of premise can be problematic for Cartesian skeptics that want to question empirical knowledge in general, since it itself is a piece of empirical knowledge.
One defense of premise B is that I might be a brain in a vat.

 Chapter 3: Humboldt and the Cartesian Tradition
The year after Cartesian Linguistics appeared, Hans Aarslef, regarded as a leading scholar in the field, published a major book "in which," Chomsky writes, "he described traditional universal grammar as solely `Cartesian' in origin, completely ignoring the quite obvious Renaissance and earlier origins that are emphasized in Cartesian Linguistics" (31 Mar. 1995).
The term "Cartesian" is not used here according to its generally accepted definition; Chomsky extends that definition to encompass, as he puts it, "a certain collection of ideas which were not expressed by Descartes, [were] rejected by followers of Descartes, and many first expressed by anti-Cartesians" (31 Mar. 1995).
The work that Chomsky assigned to the Cartesian corpus, and the tradition of research that the Cartesians had upheld, was, in Chomsky's opinion, more pertinent than the research of contemporary scholars, and certainly more useful than that which was being produced in the field of the history of linguistics.

 Information: Resurrection of the Cartesian Physics
In this regard, the Cartesian physics prior to Newtonian successor is perceptive enough to appreciate the significance of signaling and communication in the local perspective.
The Cartesian physics was rescued by forcing it to abandon its adherence to the issue of communication among the participating material bodies.
The Cartesian physics, on the other hand, is explicit in directly facing the issue of those material configurations being local both in space and in time by way of appreciating the role of signaling and communication.

 Technology Opportunity: Robust and Efficient Generation of Cartesian Meshes for CFD   (Site not responding. Last check: 2007-11-07)
Fundamentally, in Cartesian approaches, one trades the case-specific problem of generating a body-fitted surface mesh for the more general problem of computing and characterizing intersections between hexahedral mesh cells and body surfaces.
Thus, all difficulties associated with meshing a given geometry are restricted to a lower-order manifold that constitutes the wetted surface of the geometry.
Unlike the surface cells of a body-fitted mesh, the cells of a Cartesian mesh that intersect the surface are describable without describing the surface itself.

 Antoine Le Grand
In England, he taught philosophy and theology, advocating Catholicism and eventually Cartesianism, the latter being as unpopular as the former was perilous.
This problem is especially acute for Cartesians who held that there is a modal difference between what is found at the level of sensory perception and intellection, such that impressions cannot contain any of the properties found at the level of ideas.
He later rejected this view of the passions and argued the Cartesian view that the passions ought to be trained (not expunged) in the moral life.

 Test: Anyone can draw a map - why innovation is neither Radial nor Cartesian
At the risk of sounding even more 'cartesian', this is a ridiculous over-simplification, and artificially polarises the debate we were having about the impact of folksonomies as an innovation.
He then extends the cartesian analogy to explain why only companies who have a monopoly - or think they do - engage in pure research, as cartesian approaches to innovation require more resources over longer periods of time.
Instead of innovation being depicted as a single line, it is a complex network of innovations and communities [click here to see this illustrated in a pop-up window].
