 Quote: ... Now then, if you find a solution x^2 - y^2 = 0 mod T where x = 1 mod T, then you will also find that S = 2*x*k mod T solves to give k = S*(2*x)^{-1} mod T so if you solve for k FIRST, with x_res = 1 mod T, then you get the SAME ANSWER if k is a residue modulo T, understand? That is an important point.

Not really. As I said, I'm done with this method, but I'll take time to
spell out an implication you missed in my last message (I didn't spell out
every step then -- I will now).

No matter what you pick for anything, or how you go about it, these are
/requirements/ of the method:

x^2 - y^2 = 0 (modulo T) [1]
x^2 - y^2 = S - 2*x*k [2]
2*S*k = x_res (modulo T) [3]

Solving for S in [2] and substituting into [3] gives:

2*(x^2 - y^2 + 2*x*k)*k = x_res (modulo T)

But by [1], x^2 - y^2 is congruent to 0, so that becomes:

2*(2*x*k)*k = x_res (modulo T)
or
4*x*k^2 = x_res (modulo T) [4]

Then in any solution that doesn't work purely by luck, you also need:

x = x_res (modulo T)

so that [4] becomes:

4*x*k^2 = x (modulo T) [5]

Then acknowledging that it's a miracle if x isn't coprime to T (if it isn't,
use gcd(x, T) to factor and forget the rest), x has an inverse modulo T, and
[5] is then equivalent to:

4*k^2 = 1 (modulo T) [6]

You may have noticed that I derived the same thing in the context of my
specific "work backwards" example, but the derivation was shorter there
because it used specific numbers. But in fact [6] depends on nothing about
the way I picked x or x_res: if you want to pick x_res=1 instead, fine, [6]
_still_ applies. Picking S first and then solving for k doesn't change that
either. You can't get away from it. As just demonstrated, it's _inherent_
to this method that it needs to find k satisfying the quadratic congruence
[6], and that's equivalent to solving the modular square root problem, and
that in turn is known (has been proved) to be exactly as hard as factoring
T.

Nothing you say, hope, wish for, or believe can worm around that fact. If
you can solve [6] efficiently, sure, you can factor efficiently too. So
demonstrate you can solve [6] efficiently, or let go and move on. And by
"solving [6]" I mean solving it for a /given/ T, not goofiness like picking
k first and then finding T for which [6] holds (that's trivial to solve, and
irrelevant).

 Quote: ... Look over my roadmap of discoveries. Why do you think your mathematical insights are better than mine?

Partly because I believe most of your claimed discoveries are wrong (i.e,
failures to me, with a few wildly over-valued correct results), and in the
specific case of factoring integers because I routinely see how one of your
methods has to end in minutes, instead of the days, weeks, or months you
continue to struggle with one. That's not because I'm "lucky".

If you haven't noticed, I've also had much more success factoring integers
with your methods than you've had. The reason for that is that I generally
understand what your methods /actually/ do more deeply than you do.

 Quote: Just because you've seen a lot of my failures?

No. All I take from those is that for someone trying to do mathematics,
you're extraordinarily careless, generally know little about the areas you
tackle, often have trouble thinking and writing clearly, and have enormous
difficulty letting go of failed ideas. Those alone don't preclude you from

 Quote: But could you have ANY of my successes?

But I'm not willing to call incorrect claims successes, neither yours nor
mine. That puts me at a severe disadvantage, you know

[Tim Peters, to JSH, shows that if x is congruent to x_res modulo T,
and x is coprime to T, then every solution for k must satisfy:]

 Quote: ... 4*k^2 = 1 (modulo T) [6]

[and then leaps to an incorrect conclusion of his own:]

 Quote: ... If you can solve [6] efficiently, sure, you can factor efficiently too. So demonstrate you can solve [6] efficiently, or let go and move on.

I apologize for not noticing that [6] is of a special form with two easily
found solutions (assuming T is odd, and only considering solutions in [1,
T)):

k = (T+1)/2
and
k = (T-1)/2

Finding the other two solutions (when T=p*q is the product of two distinct
odd primes) is still as difficult as factoring T: [6] boils down to finding
the square roots of 1 (solve (2*k)^2 = 1 for 2*k, and then use 2^-1=(T+1)/2
to isolate k), and the solutions above correspond to +/-1. The other two
square roots of 1 are mod(+/-(p^(q-1) - q^(p-1)), T), and there's no
efficient way to find those without knowing p and q.

So you can find two solutions to [6] very easily after all. I don't know
whether they're useful solutions, but you're not going to get anywhere if
[6] isn't satisfied, and the other solutions are hard to find, so these are
worth pursuing.

 Quote: I am going to refer to Feynman's Lectures on Physics page 2-10 of the Table 2-3 of Elementary Interactions: Coupling Strength Law photon to charged particle approx 10^-2 law known gravity to all energy approx 10^-40 law known weak decays approx 10^-5 law partly known mesons to baryons approx 1 law unknown some rules known Let us consider the Coulomb force as the Unification force where weak-force combines with strong-force to become a Nuclear Coulomb in the above table. That comes to some agreement in the above table for it is very much approx. Agreement in that 10^-2 is a midpoint of functionality of 1 and 10^-5. So that combining Weak-force with Strong-force results in a Nuclear Coulomb force.

This leaves the Universe with only one force, a Coulomb force. Where
the WeakNuclear and StrongNuclear form a NuclearCoulomb. It is not by
accident that Coulomb is 10^-2 and the midpoint between WeakNuclear
10^-5 and StrongNuclear at 1.

Circa 1999 and the first several years of 2000s I thought gravity has
an antigravity force and when combining these two would make a
Electron-Region-Coulomb force just as WeakNuclear and StrongNuclear is
the nuclear region coulomb. So that a specific region of any atom has
combinations of forces which add up to a Coulomb force. So all forces
are merely Coulomb forces when combined. The NuclearCoulomb is the
broken symmetry of the Nucleus.

But now I am of the opinion that gravity has no antigravity force and
that gravity is merely a residue of Coulomb between protons holding
together electrons in an atom. Gravity is a fictional force such as
centrifugal to centripetal.

 Quote: Now to resolve gravity as a fictional force (or a residue of the Coulomb force considering that the Cosmos is the inside of a gigantic atom). In an atom, whether in chemistry lab or the Atom Totality itself, most of the mass is the nucleus and thus it bends the space around the nucleus so that the electrons travel in that bent space and we see it as an attraction force-- the Coulomb attraction.. Protons repulse other protons but in the nucleus of an atom, we have a new particle called a nuclear-electron. This is a special kind of electron because it is a whole electron and not an electron-dot-cloud. Every neutron has a nuclear-electron inside itself and this nuclear-electron when inside the space of a nucleus runs out and runs around holding together the protons in the nucleus of atoms larger than hydrogen in atomic mass.

Never did I think I would someday have to use the idea "mass bends
space". But now I must use it to reconcile how all the galaxies being a
part of the electrons of the Atom Totality can have gravity. Since we
know that electron to electron charge repulses one another.

So I need the concept that "mass bends space" to reconcile electron to
electron repulsion.

 Quote: But the Nuclear-Electron does not concern us with the night sky of our cosmos. Our cosmos is purely the electron-dot-cloud of the 231Pu Atom Totality. Galaxies are pieces of the 94 electrons of 231Pu, ditto for Sun and Earth. What we see in the night sky is all the pieces of the 94 electrons of 231Pu. Now, why do we see a force which we call "gravity"? It is identical to the Coulomb force when we replace charge with mass, only it is about 10^40 weaker in strength. Charge is mass, and mass bends space around that mass. The easy solution is that mass is charge as a function of geometry.

Here I need functionality, where mass and space are functions of one
another and which creates charge. Charge is the functionality of mass
to make clear.

Example: An electron inside a neutron is a ball and not an
electron-dot-cloud. The ball is small and compact and so the ball has
all the mass and very little space. In contrast, the electron of
hydrogen atom of its 1s is electron-dot-cloud. As if the electron had
been smashed of its mass and tiny pieces of its mass scattered around
the proton nucleus. Here the electron is a combination of the
electron-dot-cloud and the large space those electron dots are
scattered.

If we take two protons and put them close together their space may not
even be a ball shape but something different because they are repulsing
one another. The proton to electron in a hydrogen atom of 1s is
perfectly spherical because it is attractive and forms a symmetrical
geometry.

So charge as a physics concept is the function of mass and space.

 Quote: This means that gravity is fictional force.

Fictional because now we can view Coulomb force with its charge terms
as a combination of functionality of mass to space.

Planet Earth is part of the 94th electron of 231Pu ditto for the Sun.
Yet Sun and Earth attract one another, while electrons repel one
another. But this is explained in that charge is not a separate concept
from that of mass and space. The dots of electron-dot-cloud do not
repel one another, instead, they create space around them and bend
space around them and we perceive this as "gravity".

Most people reading this have the notion that space exists independent
of mass. What I am saying is that space does not exist until electrons
or an electron becomes a dot-cloud-electron. A nuclear electron or a
electron moving in a wire of electricity is a collapsed electron into a
ball and lacks the enormous space.

And the reason neutrons hold together protons is because the nuclear
electron inside the neutrons devotes its space to that of gluing
together the protons.

 Quote: In astronomy there is a very big problem of a "missing mass". It is called the Missing Mass Problem. The solution is that the mass of the cosmos is 99% in the Nucleus of the Atom Totality. Now we all know the formula E = mc^2. And we know that c = 3 X 10^8 m/s. Now can I derive the approx 10^40 force strength by Feynman's above table for the 231Pu Atom Totality. Let me give it a rough shot. The energy term E would be the 5 shells of 231Pu. This is the "5f" energy shell. This is the geometry or space functionality.

Plutonium does have 5 energy levels of 5f6. And if Charge is a
functionality between Mass and Space then the speed of light to the 5th
power does yield a force strength of approx 10^40. I need to work on
this more. And it implies that gravity is different in the nucleus then
in the electron-space region of an atom. And here we can set up
experiments to verify the differences. The old way of thinking is that
gravity is the same in all places and regions of the Universe. I am
saying that gravity would be different in the nucleus of an atom
compared to its electron space region.

 Quote: Notice that when I take 3x10^8 to the 5th power, I end up with approx 10^40. The same approx 10^40 that Feynman has in his table above. Summary: In an Atom Totality all the forces unify into one force-- Coulomb Force. The force of gravity in an Atom Totality is merely a side-effect of Coulomb. We think gravity is independent of Coulomb, when in fact it is a result of the Cosmos being a big atom held together by the Coulomb force.

I feel somewhat satisfied with gravity a fictional force, because I can
dispel the need to reconcile with a carrier particle for gravity, such
as the mythical graviton or the neutrino. A fictional force has no
carrier particle.

I am not sure yet of the mathematics involved, whether I am dealing
with composite functions for mass to space to form charge or something
more complicated. Thus I call it "functionality" at the moment.

instead. No particular constraint on k^2 follows after that correction.

Wasn't me Proving there's no possible efficient way to pick the free
variables so that "it works" would, I think, be messy. For a while I was
under the illusion (based on a transcription error in one of the equations)
that the method necessarily relied on solving a hard modular square root
problem "to work", but that's not obviously so after all.

It was rarely possible to prove (with finite effort) that last year's
methods couldn't possibly work efficiently either, and for a similar reason:
there's not much you can say about the congruence class of i+j across all
<i, j> pairs s.t. i*j = n for some fixed n. Instead mod(i+j, T) acts much
like a low-quality pseudorandom number generator (which is consistent with
observations, then and now, that the method behaves similarly to, but worse
than, the random-gcd factoring algorithm, at least in the absence of an
intelligent way to pick the free variables). However, that cuts both ways:
since there's not much you can say, it gets in the way of trying to prove it
/can/ work efficiently too.

Here _one_ of the questions is whether you can pick integer S, x_res, k, f_1
and f_2 efficiently s.t.

f_1 + f_2 = 2*(x_res + k) (modulo T)
and
f_1 * f_2 = S + k^2
and
S = 2 * x_res * k (modulo T)

And the answer is "yes": S = x_res = k = f_1 = f_2 = 0 works, leading to
the true conclusion that 0^2 - 0^2 = 0 (modulo T). Not terribly useful,
though ;-)

most of the respondents here may not know much about high level math.
With that in mind, I understand and feel the OP's pain. The difference
is I understand and appreaciate the higher level math pertaining to
pattern recognition ( one of the OP's desire ), image/signal
processing, boundary element methods etc. etc. For years and of
course - even today - matlab has been my analysis tool. For years, I
would hand matlab code to a developer and say - go code 'this'. Over
the last year or so I've done some role reversal. Granted, I'm no
Grade A programmer like most folks on here and I can't quote every
line of the standard. It remains true nonetheless, that the OP will
find that programming higher level math requires:
1. An appreciation for the standard library ( alot of those algorithms
in that library is a god send )
2. An appreciation for templates. ( I find this to be a real beast
from time to time. )

Rest assured there's quite a few programming books out there geared
towards the scientific community. Sadly, the vast majority of these
books - I've run across - are poorly written.
