Extractions: The surface of a marble table is spread out in front of me. I can get from any one point on this table to any other point by passing continuously from one point to a "neighboring" one, and repeating this process a (large) number of times, or, in other words, by going from point to point without executing "jumps." I am sure the reader will appreciate with sufficient clearness what I mean here by "neighbouring" and by "jumps" (if he is not too pedantic). We express this property of the surface by describing the latter as a continuum. So here we are describing something that is inherent in Superstring theory, and who is going to pave the way for me to understand this? By coming to the realization of the continuum, spoken by Einstein, it has made me realize, the value we could have assigned energy, and what did Kaluza do for Einstein that Einstein did for us?

The power set of N will therefore have a cardinality of Aleph_0 to teh power of 2, which is denoted by c-the cardinal number of the set of real numbers (the continuum). Cantor's hypothesis is that no infinite cardinal lies between Aleph_0 and c. continuum hypothesis is a:

To see what Day 1, Day 2, Day 3, etc. correspond to, see my syllabus Answer x.y corresponds to Day x , exercise y . When a question has sub-questions, then answer x.y.z corresponds to Day x , question y , sub-question z . Two systems S and S' may have the same theorems but different axioms and rules. This difference means they will differ in their proof theory. In S, some wff A might follow from another wff B, but this implication may not hold in S'. . Statement i is certainly true, in that every terminating, semantically bug-free program is obviously effective. Programming languages express what computers can do, and every step a computer takes is 'dumb' (even if putting many of these steps together is 'intelligent'). Statement ii may be true, but it is uncertain and unprovable. We'll never know whether a definite class of methods (those that are programmable) coincides with an indefinite class of methods (those that satisfy our intuition about 'dumbness'). The claim that statement B is true is called Church's Thesis, and will come up again on Day 27 (Hunter at 230ff). Statement i is false in this sense: many ineffective methods are programmable. Every method with an infinite loop is both ineffective and programmable.

Extractions: Abstract The Continuum Hypothesis is a modern formalization of some of mankinds most philosophical questions concerning the nature of space and time. Zeno's paradox ( c . 490-435 BC), a.k.a. the stadium paradox, argues about the infinite divisiblity of time and space. The Continuum Hypothesis was conjectured by G. Cantor (1845-1918) at the end of the 19th century and has had a crucial role on the development of set theory and is at the foundations of modern mathematical analysis. The basic statement of the continuum hypothesis is: every infinite subset of is either countable or has the same cardinality as

Extractions: I'm probably missing something obvious, but surely there is a known order type which contains ordinals of the form: a + a + ... + a i i where a i are natural numbers? Because if there is, then we can map each of its elements to a real number between and 1, and hence, it must correspond to the cardinal c. This sounds too simple to be missed by mathematicians... so what's the flaw with my reasoning here? I'm sure there must be a flaw in my reasoning somewhere. Sponsors

This Week in History Continuum hypothesis in the news In mathematics , the continuum hypothesis is a hypothesis about the possible sizes of infinite set s. Georg Cantor introduced the concept of cardinality to compare the sizes of infinite sets, and he showed that the set of integer s is strictly smaller than the set of real number s. The continuum hypothesis states the following: There is no set whose size is strictly between that of the integers and that of the real numbers. Or mathematically speaking, noting that the cardinality for the integers is aleph-null ") and the cardinality for the real numbers is , the continuum hypothesis says: The real numbers have also been called the continuum , hence the name. There is also a generalization of the continuum hypothesis called the generalized continuum hypothesis , which is described at the end of this article. Consider the set of all rational number s. One might naively suppose that there are more rational numbers than integers, and fewer rational numbers than real numbers, thus disproving the continuum hypothesis. However, it turns out that the rational numbers can be placed in one-to-one correspondence with the integers, and therefore the set of rational numbers is the same size as the set of integers: they are both countable set s.
