what do you call this re-ordering operation on a list?
Given a list, what do you call the reordering operation that you get by stepping through the elements of a list n positions at a time, considering the list to wrap around? For instance, here's my list, L=[a,b,c,d,e,f]. I'll call the operation Q_n, where n is the number of positions to move at a time. Q_1(L) = ... 3 Jul 2010 02:38

Proton Radius derived from "Nobel Prize-winning" hedge-fund formula: BP's cap&trade!
rocks o'light, squeezin' thru th'aether; A=Mcc -- yahoo!TM. thus&so: numbertheory was always the ****, the higher arithmetic, the king of the sciences etc., but no more important than theo ther three elements of *mathematica*.

Is Mathematics for selling your free-beer-miles to BP's cap&trade -- with CO2 creds at ARCO?
numbertheory was always the ****, the higher arithmetic, the king of the sciences etc., but no more imprtant than theother three elements of *mathematica*, When asked what good numbertheory was, Landau said, many people had gotten Ph.D.s in it. thus&so: so, acid rain is the germain topic, since it was t... 2 Jul 2010 15:45

Global Warming - BP's cap&trade legislators & agitprop Beyond Phossilized Phuels (TM)
like, I typed, before. thus&so: so, acid rain is the germain topic, since it was the First Cap and Trade (Waxman's '91 bill). so, what I haven't seen dyscussed in the WSUrinal e.g., is just how wonderfully this'd worked -- who made the money in the God-am "free market?" [NB, Waxman's cmte. also ran the health... 2 Jul 2010 15:45

using geometry's finite-line & infinite-line and line rays to hopefully well-define finite-number & infinite-number #623 Correcting Math
So let me try going from geometry's precision well-defining of finite- line versus infinite-line to see if I can well-define Algebra's numbers. I do not expect to make progress on this because geometry has three different types of geometry with its NonEuclidean elliptic and hyperbolic. One thing is sure, tha... 2 Jul 2010 14:38

More on Fibonacci numbers, Lucas numbers, and primes in progressions
I made an earlier post asking if it were known that any prime divisor of L(p) was congruent to 1 mod p and observed the implication that this allowed is to give an effective bound to the size of such a prime in a completely trivial way. I was using fairly complicated methods in pursuit of a completely different go... 10 Jul 2010 16:01

Classification of semi-simple Lie groups
A while ago I heard the following two facts about semi-simple Lie groups (though I have a feeling they may have to be restricted to connected semi-simple Lie groups): 1. That semi-simple Lie groups are classified by their weight (and co- weight) and root (and co-root) lattices; 2. That all of these lattices can ... 3 Jul 2010 10:08

The set of all SUBSETS that don't contain themself -> PARADISE
The set of all SETS that don't contain themself -> PARADOX The set of all SUBSETS that don't contain themself -> PARADISE This is the status quo of early 21ST Century mathematics. In the 2nd subset version you can (attempt to) list the subsets and contain refers to the list position being an element of th... 5 Jul 2010 12:12

HERE is a list that contains ALL possible infinite sequences of digits
As the length of the list of computable reals->oo, the length of all possible digit sequences on the list->oo. What's your explanation for what happens if the list IS infinitely long? All sequences doesn't quite make it to infinity?? It misses some? Herc -- "George Greene" <greeneg(a)email.unc.edu> wrote ... 5 Jul 2010 02:25
