In this process, I do not need to "cover" 2 or 3 or 4.

Actually Cantor made an error. It was in one of his first papers where he wrote that you also could sort of count with transfinite numbers, and you the numbers you could count where those of the same class. If I remember correctly (I do not have the book here at home) he made the error that you needed a number of a higher class when counting all numbers of a particular class. I will try to find it tomorrow (it is in the first article where he uses omega). -- dik t. winter, cwi, kruislaan 413, 1098 sj amsterdam, nederland, +31205924131 home: bovenover 215, 1025 jn amsterdam, nederland; http://www.cwi.nl/~dik/ |
