Mathematics Revenge How numbers don't behave as they should! www What I don't understand about Cantor Infinities Cantor defines w w elements. The reason this is called an Ordinal Infinity is because the set of numbers has a specific ordering: 2 always follows 1, etc. This set of Ordinal Numbers does not itself include Infinity ( Inf ) since Inf is not a number you can count. For more information on this please visit: Robert Munafo's Large Number Pages Section 4 Eric Weisstein's MathWorld page on Ordinal Numbers Following the logical definition of w , Cantor further devised the concept of even larger sets. If you imagine w w because w is Inf . Adding w to that set would produce a set 1 bigger than w , which Cantor denoted w + 1. It must be noted however that Cantor did not consider 1 + w to be the same as w w w w w but w w Cantor further defined even larger sets. Like with integers, normal mathematical operations could be applied to Cantor's infinities. Thus, w w + 1 because w w + 1 + 1, where w w w w w w w w w w - 1 is a place holder for the last integer in the w w w in the same way we do normal integers: w 2. By analogy, Cantor went further to define

2. The Repressed Content-Requirements Of Mathematics HBT requires uncountable infinities of rotations. Cantor's interpacking of infinite decimals Wittgenstein's arguments against cantor's infinitiesin turn considered idiotic by most http://www.henryflynt.org/studies_sci/reqmath.html

Back to H.F. Philosophy contents The Repressed Content-Requirements of Mathematics Henry Flynt [started c. 1987; this draft 1994] (c) 1994 Henry A. Flynt, Jr. A. Mathematics, as it is conceived in the twentieth century, has presuppositions about perception, and about the comprehension of lived experience relative to the apprehension of apparitions, which are repressed in professional doctrine. It also has presuppositions of a supra-terrestrial import which are repressed. The latter concern abstractions whose reality-character is an incoherent composite of features of sensuous-concrete phenomena. In the twentieth century, mathematicians have been taught to say by rote, "We are beyond all that now. We are beyond psychology, and we are beyond independently subsisting abstractions." This recitation is a case of denial. Indeed, if this recitation were true, it would allow mathematics nowhere to live. Certainly social conventionsbeloved by the Vienna Circleare too unreliable to found the truths which mathematicians claim to possess. (Truths about the decimal value of [pi], or about different sizes of infinity, for example.) To uncover the repressed presuppositions, a combination of approaches is required. (One anthropologist has written about "the locus of mathematical reality"but, being an academic, he merely reproduces a stock answer outside his field, namely that the shape of mathematics is dictated by the physiology of the brain.)

Links In the example on the previous page, student B matched each number with its double, which resulted in the following correspondence: The integers can be put into correspondence with the natural numbers like this: Now, Cantor made the following definition: Definition : Two sets are equal in magnitude (i.e. size) if their elements can be put into one-to-one correspondence with each other. This means that the natural numbers, the integers, and the even integers all have the 'same number' of elements. Cantor denoted the number of natural numbers by the transfinite number (pronounced aleph-nought or aleph-null). For ease of notation, we will call this number d, since the set of all natural numbers (and all sets of equal magnitude) are often called denumerable , a , a corresponds to the natural number 1, a to 2, and so on. Theorem: The set of rational numbers is denumerable, that is, it has cardinal number d.

OK (let's agree or at least pretend!) - a line contains an infinite number of points - a plane contains an infinite number of lines; that is a plane contains an infinite number of lines each line with an infinite number of points. Seems like a plane should have an infinite number of points more than the infinite number of points in the line. This is a comparison of two like kinds/classes of infinity so they (the number of points in a line and the number of points in a plane) are really-really equal. If those two infinities are equal (equal means, "every point in a plane can be mapped to a single unique point in a line and the converse is true") than describe such a (isomorphic) mapping. thanks - chris-m Send to a Friend Printer Friendly Sign Up to See Solution Sign Up to See Solution Member Name (cannot be changed) Email Address

5. Untitled in the building of stronger theoretical foundations, nonEuclidean geometries, and cantor's infinities we shall see in Cantor's work on infinities, geometry contains a problem http://www.andrews.edu/~closserb/215_Logan.html

INDEPENDENCE AS IT INFLUENCED THE DEVELOPMENT OF THE AMERICAN IDENTITY AND THE DEVELOPMENT OF MATHEMATICS IN THE NINTEENTH CENTURY Clara Logan During the 1800s, we find the theme of independence, or freedom from outside constraints, in the development of two different frontiers. We find it in the American West through Manifest Destiny, freedom from caste, and in the chance that homesteaders had to acquire virtually free land. We find independence in math through in the building of stronger theoretical foundations, non-Euclidean geometries, and Cantor's infinities. Independence involves breaking from the commonly accepted, traditional views in order to explore the new. It is not necessarily individual people working alone. We can see independence in a community of thought as well as in the work of a single person. The concept of Manifest Destiny is also seen in the actions of the common people. These common people included the family of my great grandmother's grandmother, Mary Rocell. In the 1880s, Hulda Rocell and her daughter Mary emigrated from Sweden to the United States. Abe Lincoln had just been shot. Mr. Rocell had to stay in Sweden because of his tuberculosis. Nevertheless, Mr. Rocell said, "Go to the United States. It is strong enough that Lincoln's assassination will not plummet the nation into chaos." Although he did not place this optimism under the title of Manifest Destiny, the idea that the United States is strong, and will continue despite opposition, is a part of this concept.

Zeno's Paradox A Math Forum Project Table of Contents: Famous Problems Home The Bridges of Konigsberg The Value of Pi Prime Numbers ... Links The great Greek philosopher Zeno of Elea (born sometime between 495 and 480 B.C.) proposed four paradoxes in an effort to challenge the accepted notions of space and time that he encountered in various philosophical circles. His paradoxes confounded mathematicians for centuries, and it wasn't until Cantor's development (in the 1860's and 1870's) of the theory of infinite sets that the paradoxes could be fully resolved. Zeno's paradoxes focus on the relation of the discrete to the continuous, an issue that is at the very heart of mathematics. Here we will present the first of his famous four paradoxes. Zeno's first paradox attacks the notion held by many philosophers of his day that space was infinitely divisible, and that motion was therefore continuous. Paradox 1: The Motionless Runner A runner wants to run a certain distance - let us say 100 meters - in a finite time. But to reach the 100-meter mark, the runner must first reach the 50-meter mark, and to reach that, the runner must first run 25 meters. But to do that, he or she must first run 12.5 meters. Since space is infinitely divisible, we can repeat these 'requirements' forever. Thus the runner has to reach an infinite number of 'midpoints' in a finite time. This is impossible, so the runner can never reach his goal. In general, anyone who wants to move from one point to another must meet these requirements, and so motion is impossible, and what we perceive as motion is merely an illusion.

8. Cantor's Diagonal Proof cantor's Diagonal Proof. Simplicio I'm trying to understand the significance of cantor's diagonal proof. I find it especially confusing that the rational numbers are considered to be countable, but http://www.mathpages.com/home/kmath371.htm

Cantor's Diagonal Proof Simplicio: I'm trying to understand the significance of Cantor's diagonal proof. I find it especially confusing that the rational numbers are considered to be countable, but the real numbers are not. It seems obvious to me that in any list of rational numbers more rational numbers can be constructed, using the same diagonal approach. Interfering With PI Simplicio: You said there is no upper bound on the size of natural numbers, and thus the least upper bound on the naturals is infinite, even though every natural number is finite. To me this implies that there can be numbers which do not have such a bound. Is that not so? Salviati: It sounds like you're trying to invent a kind of "number" that has infinitely many digits in the direction of geometrically increasing significance, somewhat analagous to the reals, which have infinitely many digits in the direction of geometrically decreasing significance. Number systems like what you are talking about have actually been developed, Simplicio, (see p-adic numbers) but the crucial difference is that the infinite sequence of digits is in the direction of increasing, not decreasing, significance, so the resulting implied "sum" does not converge to a value that behaves consistently like a magnitude. (The valuations are said to be "non- Archimedian".) There's nothing wrong with conceiving new forms of numbers like this, but we need to be clear about how they differ from other forms of numbers.

9. Cantor's Diagonal Proof These numbers would, of course, also be infinite, but would be larger infinities than the standard infinity, ¥, that we are used to. Cantor called these http://home.ican.net/~arandall/abelard/math12/Cantor.html

Cantor’s Diagonal Proof Cantor introduced the idea of sets. A set was, for Cantor, a purely intuitive concept, not formally defined. A set is a kind of collection of objects that we can imagine intuitively in our minds. We can speak, for instance, of the set of all red things. Or a set can contain other sets, such as the set of all sets of coloured things. . However, Cantor asked us to consider that there could be larger numbers than infinity. These numbers would, of course, also be infinite, but would be larger infinities than the standard infinity, , that we are used to. Cantor called these numbers "transfinite" numbers. After , we get ( + 2), and so on. So what is the cardinality, or size, of ( . But, in fact, I can place all the elements of the first set into a one-to-one correspondence with the second, like so: Cantor defined the size of his sets so that any two sets that could be matched up one-to-one like this were considered to be the same size. The same holds true for any finite number of new elements I insert into the set. Note that it does not really matter that I placed the new element at the beginning, since the one-to-one match-up would still hold no matter where I inserted the new element. So it really makes no sense to say that one of these sets is larger than the other. In other words, + 1, and we do not seem to have created a larger number with

The Continuum Hypothesis 4. Axiomatic Set Theory ... Related Entries 1. The Essence of Set Theory The objects of study of Set Theory are sets . As sets are fundamental objects that can be used to define all other concepts in mathematics, they are not defined in terms of more fundamental concepts. Rather, sets are introduced either informally, and are understood as something self-evident, or, as is now standard in modern mathematics, axiomatically, and their properties are postulated by the appropriate formal axioms. The language of set theory is based on a single fundamental relation, called membership . We say that A is a member of B (in symbols A B ), or that the set B contains A as its element. The understanding is that a set is determined by its elements; in other words, two sets are deemed equal if they have exactly the same elements. In practice, one considers sets of numbers, sets of points, sets of functions, sets of some other sets and so on. In theory, it is not necessary to distinguish between objects that are members and objects that contain members the only objects one needs for the theory are sets. See the supplement Basic Set Theory for further discussion.

11. Cantor's Diagonal Argument The great granddaddy of diagonal arguments is Cantor s, which proved that some infinities are bigger than others. Cantor s Diagonal Argument. http://www.chaos.org.uk/~eddy/math/diagonal.html

Diagonal arguments Various arguments prove extremely strong results by phrasing the result in such a way that some `two-parameter' thing can be used to supply a `diagonal', the special case where the two-parameter thing has both parameters equal, analysis of which suffices to prove some property of the two-parameter thing which suffices to imply the desired strong result. The great grand-daddy of diagonal arguments is Cantor's, which proved that some infinities are bigger than others. Cantor's Diagonal Argument can can enumerate any set of subsets of the naturals as long as there's an upper (finite) bound on the size of the subsets. One may use each natural in turn as choice of upper bound and construct an enumeration of all the subsets of the naturals smaller than this. It might seem that `in the limit at infinity' this process should get us at least an enumeration of all finite sub-sets of the naturals; and one might hope that some analogous trickery might enable one to get all sub-sets of the naturals. In any case the diagonal argument shows only one The diagonal argument can be read as an algorithm for converting a function, from a set to its power set, into a function from the set's successor to

And then until my ability to conceive of it was overwhelmed, and I woke up in a highly anxious state. and then I was awake, wide-eyed and perspiring.

It is called the Von Neumann heirarchy , and it is a construction in set theory.
