A cohort of subjects was surveyed       their opinion and belief whether .999, dot dot dot,       was equal to, or less than, one. About half said       same and about half said different.                     It's two different natural notations that happen       to collide and thus result being ambiguous.              So, then these days we have the laws of arithmetic       introduced in primary school, usually kindergarten,       about the operations on numbers, and also inequalities,       and the order in numbers.              Yet, even the usual account of addition and its       inverse and its recursion and that's inverse,       as operators, of whole numbers, has a different       account, of increment on the one side, and, division       on the other, sort of like the Egyptians only had       division or fractions and Egyptian fractions,       and tally marks are only increment, that though       it was the Egyptian fractions that gave them a       mathematics, beyond the simplest sort of conflation       of "numbering" and "counting".              So, where ".999 vis-a-vis 1" has a deconstructive account,       to eliminate its ambiguities with respect to what it's       to model, or the clock-arithmetic and field-arithmetic,       even arithmetic has a deconstructive account, then,       even numbering versus counting has a deconstructive account,       to help eliminate what are the usually ignored ambiguities.                     So, pre-calculus, the course, goes to eliminate or talk       away the case .999, dot dot dot, different 1. Yet,       it can be reconstrued and reconstructed, on its own       constructive account. So, it's a convention.                     It's "multiplicity theory", see, that any, "singularity       theory", which results as of admitting only the principal       branch of otherwise a "bifurcation" or "opening" or "catastrophe"       or "perestroika (opening)", as they are called in mathematics,       branches, that singularity theory is a multiplicity theory,       yet the usual account has that it's just nothing,       or that it's apeiron and asymptotic.                     So, there's a clock arithmetic where there's a reason why       that there's a .999, dot dot dot, _before_ 1.0, in the       course of passage of values from 0, to 1, and, it's also       rather particularly only between 0 and 1, as what results       thusly a whole, with regards to relating it to the modularity       of integers, the integral moduli.              Thusly, real infinity has itself correctly and constructively       back in numbers for "standard infinitesimals" here called       "iota-values".              Then, this is totally simple and looks like f(n) = n/d,       for n goes from zero to d and d goes to infinity, this       is a limit of functions for this function which is not-       a- real- function yet is a nonstandard function and that       has real analytical character, it's a discrete function       that's integrable and whose integral equals 1, it illustrates       a doubling-space according to measure theory in the measure problem,       it's its own anti-derivative so all the tricks about the exponential       function in functional analysis have their usual methods about it,       it's also a pdf and CDF of the natural integers at uniform random,       of which there are others, because there are at least three laws       of large numbers, at least three Cantor spaces, at least three       models of continuous domains, and, at least three probability       distributions of the naturals at uniform random.              So, "iota-values" are not the same thing as the raw differential,       which differential analysts will be very familiar with as usually       not- the- raw- differential yet only as under the integral bar       in the formalism, yet representing about the solidus or divisor bar       the relation of two quantities algebraically, then indeed there's       that "iota-values" are as of some "standard infinitesimals", yet       only under the limit of function the "natural/unit equivalency function"       the N/U EF, about [0,1]. This thus results a model of       a continuous domain "line reals" to go along with the usual standard       linear curriculum's "field reals" then furthermore later there's       a "signal reals" of at least these three models of continuous domains.                     The usual demonstration after introducing the repeating terminus       and using algebra to demonstrate a fact about arithmetic,       is good for itself, and is one of the primary simplifications       of the linear curriculum, yet as a notation, it's natural that       two different systems of notation can see it variously, then       that it merely demands a sort of book-keeping, to disambiguate it.              If you ever wonder why mathematics didn't have one of these,       or, two of these as it were together, it does, and it's only       a particular field of mathematics sort of absent the super-classical       and infinitary reasoning, that doesn't.              Then at least we got particle/wave duality as super-classical,       then Zeno's classical expositions of the super-classical were       just given as that the infinite limit as introduced in pre-calculus       said we could ignore the deductive result that it really must complete,       the geometric series.              --- SoupGate-DOS v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
