Laying the Foundation with Respect

It is most certain that at this point the public would have been left behind, so is there a way to bring perspective at this point on where you are now?

I recognize the generalization and roads that lead to blackhole as a basis for considerations. What would draw ones atyemtion to this horizon. Lee Smolin in his book gave adequate discription that I just pointed out here.

Three Roads to Quantum Gravity, by Lee Smolin, pg 171


I know it might seem that if this conversation is now highlighting the intricacies of blackhole dynamics, then what exactly are you doing?



By giving a visual map of the Bekenstein Bound this help to direct my attention to the mapping that had been going on theorectically here.

Mine would definitiely be generalizations, but work by others lead to deeper insights.

Conformal Field Theory

A conformal field theory is a quantum field theory (or statistical mechanics model at the critical point) that is invariant under the conformal group. Conformal field theory is most often studied in two dimensions where there is a large group of local conformal transformations coming from holomorphic functions.


So what "tidbits" had already been out there then that would help.


Black Holes and Beyond:
Harvard's Andrew Strominger on String Theory

Quantum Micostates?

The old version of string theory, pre-1995, had these first two features. It includes quantum mechanics and gravity, but the kinds of things we could calculate were pretty limited. All of a sudden in 1995, we learned how to calculate things when the interactions are strong. Suddenly we understood a lot about the theory. And so figuring out how to compute the entropy of black holes became a really obvious challenge. I, for one, felt it was incumbent upon the theory to give us a solution to the problem of computing the entropy, or it wasn't the right theory. Of course we were all gratified that it did.


While this is a past issue for most of you it is leading in the direction you are talking I assume.


Holography encodes the information in a region of space onto a surface one dimension lower. It sees to be the property of gravity, as is shown by the fact that the area of the event horizon measures the number of internal states of a blackhole, holography would be a one-to-one correspondance between states in our four dimensional world and states in higher dimensions. From a positivist viewpoint, one cannot distinquish which discription is more fundamental.

Pg 198, The Universe in Nutshell, by Stephen Hawking

Gary T. Horowitz and Juan Maldacena,

The purpose of this note is to provide a possible answer to this question. Rather than the radical modification of quantum mechanics required for pure states to evolve into mixed states, we adopt a more mild modification. We propose that at the black hole singularity one needs to impose a unique final state boundary condition. More precisely, we have a unique final wavefunction for the interior of the black hole. Modifications of quantum mechanics where one imposes final state boundary conditions were considered in [6,7,8,9]. Here we are putting a final state boundary condition on part of the system, the interior of the black hole. This final boundary condition makes sure that no information is “absorbed” by the singularity.


While there is no "apparent relationship(?)" between microstate blackhole production and blackholes what would make one think that particle collsions can be written as dual blackholes?

What are those Quantum Microstates

Now two points occupy my mind that hold questions as to what and how such counting can be done in terms of geometric propensity, that would allow these geometries into topological states. First point is:

Lubos Motl said:
We need to get closer to the "theory of everything", regardless of the question whether the destination is a finite or infinite distance away. (And yes, the path should not be infinitely long because there is no physics "below" the Planck length.)


And the second:

Black holes and branes in string theory

But it has been discovered through string duality relations that spacetime geometry is not a fundamental concept in string theory, and at small distance scales or when the forces are very strong, there is an alternate description of the same physical system that appears to be very different.


So what then would say that non linear approaches would now have taken form in our talks, that what was once geoemtrically feasible, had been taken down to the length where no new geometry is involved. So lets see then how shall we verbalize what happens at the horizon, in terms of radiation, that such states never existed to make this possible?

Now there are always reasons that one moves into the historical to gain perspective. By doing this, you gain insight and advance thinking to reveal theoretical developement, and where it has taken us. So by using thse linked paragraph statements, we are revealling something about Blackholes that had been culminative, to have discussions in todays world. Like BPS blackhole dynamics.

Andrew Strominger is an American theoretical physicist who works on string theory. He is currently a professor at Harvard University and a senior fellow at the Society of Fellows. His contributions to physics include:


Now one thing that troubles me about Lubo's statement, is the idea that supersymmetry valuation could ever be entertained, had we not consideedr this avenue of some importance. Not just in terms of symmetry breaking, but of the illustrous states of existance, that would exemply this idea where the superfluid could rest itself, and provide for the base of operation for these new universes?

To the second point, by providing for the idea of a geometry to emerge from this vast ocean of vast probabilites. Again for me, to see this I recognized that "space is not empty", and that such a congregation of gravitonic perception would have to be culminative, in some form for such a superfluid to exist?

So one had to get there geometrically from this ten dimensional perspective to have some basis to fuel developement into other stages of existance. Some geometric form, that would reduce, such valuations to supersymmetrical thinking and allow such a developemental process to cyclical natures. of that same universe.

Strominger: That was the problem we had to solve. In order to count microstates, you need a microscopic theory. Boltzmann had one–the theory of molecules. We needed a microscopic theory for black holes that had to have three characteristics: One, it had to include quantum mechanics. Two, it obviously had to include gravity, because black holes are the quintessential gravitational objects. And three, it had to be a theory in which we would be able to do the hard computations of strong interactions. I say strong interactions because the forces inside a black hole are large, and whenever you have a system in which forces are large it becomes hard to do a calculation.

The old version of string theory, pre-1995, had these first two features. It includes quantum mechanics and gravity, but the kinds of things we could calculate were pretty limited. All of a sudden in 1995, we learned how to calculate things when the interactions are strong. Suddenly we understood a lot about the theory. And so figuring out how to compute the entropy of black holes became a really obvious challenge. I, for one, felt it was incumbent upon the theory to give us a solution to the problem of computing the entropy, or it wasn't the right theory. Of course we were all gratified that it did.


So indeed then three conditions had been satisfied, that issues about the physics involved had something to say about quantum mechanics, gravity and computation of entrophy of blackholes respectively.


The animation shows schematically the behavior of the gas molecules in the presence of a gravitational field. We can see in this figure that the concentration of molecules at the bottom of the vessel is higher than the one at the top of the vessel, and that the molecules being pushed upwards fall again under the action of the gravitational field.


What is black hole entropy?

Suppose we have a box filled with gas of some type of molecule called M. The temperature of that gas in that box tells us the average kinetic energy of those vibrating molecules of gas. Each molecule as a quantum particle has quantized energy states, and if we understand the quantum theory of those molecules, theorists can count up the available quantum microstates of those molecules and get some number. The entropy is the logarithm of that number.
When it was discovered that black holes can decay by quantum processes, it was also discovered that black holes seem to have the thermodynamic properties of temperature and entropy. The temperature of the black hole is inversely proportional to its mass, so the black hole gets hotter and hotter as it decays.


Microstate Blackhole Production

Peter Steinberg
Unfortunately, all of this is overstated. At RHIC we don't make a "real" black hole, in the sense envisioned by Einstein's General Theory of Relativity. Rather, Nastase's point of view is that RHIC collisions can be described by a "dual" black hole. But what does "dual" mean in this context? It's not "two-ness" in any sense, but rather indicates that one can write down a theory which describes the collision as a black hole, but in a completely different world than that we see around us. To make his model work, he (and many other researchers who are exploring this direction) make a calculation of a black hole in 10 dimensions in order to describe difficult (but gravitationally benign) aspects of the strong interaction in 4 dimensions.

Entanglement Interpretation of Black Hole Entropy

"Entanglement entropy" is the latest article posted by Lubos Motl. From this ideas are brought back for consideration, with Nigel and myself in trying to explain. I am not to swift sometimes in my explanations, so the inudation of links here direct underscore the probabilistic valuation one might assign perspective in relation to the topic assigned by Lubos in titled Link.



Plato said:
I was going after consensus in terms of how temperature on Bekenstein bound was seen in context of 5th dimenison and 5d comparisons.

Bekenstein image is very useful here as was Lee Smolins discription.




If not in your surprize(?) I do not think Lubos Motl and Lee Smolin are too far apart? Here is a better picture of the Lava lamp. The Window on the Universes, has extended our understanding here as well.



Entanglement Interpretation of Black Hole Entropy in String Theory

This allows the comparison of the entanglement entropy with the entropy of the field theory dual, and thus, with the Bekenstein-Hawking entropy of the black hole. As an example, we discuss in detail the case of the five dimensional anti-de Sitter, black hole spacetime

Glast determination in "calorimeric views" would be consistent the deeper look of gluonic perception at such levels? It would be hard to know this starting point yet the environment is conducive, non?




  • Three quarks indicated by red, green and blue spheres (lower
    left) are localized by the gluon field.



  • A quark-antiquark pair created from the gluon field is
    illustrated by the green-antigreen (magenta) quark pair on the right. These quark pairs give rise to a meson cloud around the proton.



  • The masses of the quarks illustrated in this diagram account for only 3% of the proton mass. The gluon field is responsible for the remaining 97% of the proton's mass and is the origin of mass in most everything around us.


  • Experimentalists probe the structure of the proton by scattering electrons (white line) off quarks which interact by exchanging a quantum of light (wavy line) known as a photon.


    Remember that the age is determined by the dark matter density. Mathematically, the length is roughly the geometric mean of the mean free path and the distance light can travel without obstruction (the horizon scale).

    The Fifth Dimension, is the Spacetime Fabric

    Perhaps Quantum Gravity can be Handled by thoroughly reconsidering Quantum Mechanics itself? by Gerard t' Hooft

    I was attracted to Nigel Cook's statement on Peter Woits blog entitled, "Panel Discussion Video" by the quote of his taken here below. What immediately struck my mind, was the Bekenstein Bound and how "temperature" would have been seen from that perspective.

    Bekenstein Bound:
    Superstring theory rules in the 5-D spacetime, but a so-called conformal field theory of point particles operates on the 4-D hologram. A black hole in the 5-D spacetime is equivalent to hot radiation on the hologram--for example, the hole and the radiation have the same entropy even though the physical origin of the entropy is completely different for each case.


    Lee Smolin post given at Peter Woit's site was a ressurrection of "Three Roads to Quantum Gravity", and I like the fact that he wants cohesion amongst physicists and theoriticians alike. But if stauchly held to any position, then you have divisive comment about the ways in which to approach things. It can't be helped. But asking for more clarity this might be a good thing, and a approach by Lubos to qualify the string theorist position.

    Lubos Motl:
    The holographic conjecture, based on the Bekenstein's bounds and the Bekenstein-Hawking entropy of the black hole,has been first proposed by Gerard 't Hooft and discussed in more detail by Lenny Susskind:


    But before consider Nigel's comment, I wanted to quote something from Lee Smolin.

    Consider any physical system, made of anything at all- let us call it, The Thing. We require only that The Thing can be enclosed within a finite boundary, which we shall call the Screen(Figure39). We would like to know as much as possible about The Thing. But we cannot touch it directly-we are restrictied to making measurements of it on The Screen. We may send any kind of radiation we like through The Screen, and record what ever changes result The Screen. The Bekenstein bound says that there is a general limit to how many yes/no questions we can answer about The Thing by making observations through The Screen that surrounds it. The number must be less then one quarter the area of The Screen, in Planck units. What if we ask more questions? The principle tells us that either of two things must happen. Either the area of the screen will increase, as a result of doing an experiment that ask questions beyond the limit; or the experiments we do that go beyond the limit will erase or invalidate, the answers to some of the previous questions. At no time can we know more about The thing than the limit, imposed by the area of the Screen.


    Page 171 and 172 0f, Three Roads to Quantum Gravity by Lee Smolin

    Nigel Cook:
    'Caloric’, fluid heat theory, eventually gave way to two separate mechanisms, kinetic theory and radiation. This was after Prevost in 1792 suggested constant temperature is a dynamic system, with emission in equilibrium with the reception of energy.


    Yet I understand this call for bringing a string theorist into the fold of Lee's, but I would remind him, that such cosmological approaches are well on their way with the course ISCAP set for themselves and how comsological realization, are still important features that string theory would like to get a hold of.



    Juan Maldacena:
    The strings move in a five-dimensional curved space-time with a boundary. The boundary corresponds to the usual four dimensions, and the fifth dimension describes the motion away from this boundary into the interior of the curved space-time. In this five-dimensional space-time, there is a strong gravitational field pulling objects away from the boundary, and as a result time flows more slowly far away from the boundary than close to it. This also implies that an object that has a fixed proper size in the interior can appear to have a different size when viewed from the boundary (Fig. 1). Strings existing in the five-dimensional space-time can even look point-like when they are close to the boundary. Polchinski and Strassler1 show that when an energetic four-dimensional particle (such as an electron) is scattered from these strings (describing protons), the main contribution comes from a string that is close to the boundary and it is therefore seen as a point-like object. So a string-like interpretation of a proton is not at odds with the observation that there are point-like objects inside it.

    Dealing With a 5d World

    A black hole is an object so massive that even light cannot escape from it. This requires the idea of a gravitational mass for a photon, which then allows the calculation of an escape energy for an object of that mass. When the escape energy is equal to the photon energy, the implication is that the object is a "black hole".


    A lot of us understand I think that the cosmological world we had been lead through by Einstein, has geometrical principals embued with this organizational ascent. So too alongside of this equative understanding, the geometry must be understood as well, as the role we have in develoing to non euclidean geometry.

    The basic principals have direct physics results as we learn to explore these potentials.



    If we are taken to understand this progression, how did we get here? Are there higher dimensions without the geometry?



    Measuring the depth of ideas

    Lubos saids:Instead, let us ask: is quantum mechanics deep? Yes, I think that quantum mechanics is perhaps the deepest idea we know. It is once again a deformation of a conceptually simpler picture of classical physics. Much like the speed of light is finite in relativity and it unifies space and time, the Planck constant is finite in quantum mechanics which allows us to identify the energy with the frequency, among many other things - quantities that would otherwise remain as independent as space and time without relativity.

    Lubos Motl talk about the depth of ideas, for me, leads to this progression of geometry. Talked about it in a way I saw leading and consenting ideas to this progression, by developing these deeper qualities of "quantum mechanics".

    We had to understand then that such a physics progression would follow hand in hand, with the ideas of geometrical expression? So how were we lead into the non-eucldean world?



    So too then, how would it be, if we use a different method to extoll the holographical understanding in how we percieve the natural abilties of information related to this geometrical form? Bekenstein Bound holds important clues about this fifth dimensional attribute?

    Holography encodes the information in a region of space onto a surface one dimension lower. It sees to be the property of gravity, as is shown by the fact that the area of th event horizon measures the number of internal states of a blackhole, holography would be a one-to-one correspondance between states in our four dimensional world and states in higher dimensions. From a positivist viewpoint, one cannot distinquish which discription is more fundamental.

    Pg 198, The Universe in Nutshell, by Stephen Hawking

    How would then would we reduce Higher dimensions to relativity?

    Superstring theory rules in the 5-D spacetime, but a so-called conformal field theory of point particles operates on the 4-D hologram. A black hole in the 5-D spacetime is equivalent to hot radiation on the hologram--for example, the hole and the radiation have the same entropy even though the physical origin of the entropy is completely different for each case. Although these two descriptions of the universe seem utterly unalike, no experiment could distinguish between them, even in principle.

    Why No New Einstein

    To them, I said,
    the truth would be literally nothing
    but the shadows of the images.
    .
    -Plato, The Republic (Book VII)

    The inference of dimensional attributes scares many good minds away from the matters at hand?:)

    Lubos Motl:
    The only truly open questions about the interpretation of quantum mechanics are those that also require us to understand dynamics of quantum gravity properly.




    I think Gerard t' Hooft would like to change the way we see quantum mechanics? Non!

    The Holographical Principle

    I must add a very important note. It is still hard for me to believe that Lee Smolin wrote something that could imply that *he* was the author of the conjecture. Lee Smolin has nothing to do with the discovery of the holographic principle and I hope that he always refers to the real authors properly-and it was just you who did not read carefully enough. The holographic conjecture, based on the Bekenstein's bounds and the Bekenstein-Hawking entropy of the black hole,has been first proposed by Gerard 't Hooft and discussed in more detail by Lenny Susskind:



    But my point is, that if we are lead to the understanding of gravity as GR does, then why would we not entertain the idea, that there are forces of gravity stronger, and areas, that are weaker?

    Of course, to Plato this story was just meant to symbolize mankind's struggle to reach enlightenment and understanding through reasoning and open-mindedness. We are all initially prisoners and the tangible world is our cave. Just as some prisoners may escape out into the sun, so may some people amass knowledge and ascend into the light of true reality.

    What is equally interesting is the literal interpretation of Plato's tale: The idea that reality could be represented completely as `shadows' on the walls


    How will the photon respond in such shadows?

    Why would we not extend this vision from GR understanding well, that such resistance by Einstein, required deeper thinkers to respond to the theory that they had put forth in Solvay?


    by Jacob D. Bekenstein
    TWO UNIVERSES of different dimension and obeying disparate physical laws are rendered completely equivalent by the holographic principle. Theorists have demonstrated this principle mathematically for a specific type of five-dimensional spacetime ("anti–de Sitter") and its four-dimensional boundary. In effect, the 5-D universe is recorded like a hologram on the 4-D surface at its periphery. Superstring theory rules in the 5-D spacetime, but a so-called conformal field theory of point particles operates on the 4-D hologram. A black hole in the 5-D spacetime is equivalent to hot radiation on the hologram--for example, the hole and the radiation have the same entropy even though the physical origin of the entropy is completely different for each case. Although these two descriptions of the universe seem utterly unalike, no experiment could distinguish between them, even in principle.


    It is thus, it challenged the views, of even the most determined thinkers, professional or not, once the paradox of thought experiment was introduced? Set the targets for research and developement and the initiatives of the younger generation to excell where the limtations had been drawn.

    So in the one sense such a strong stance by Einstein was the incentive for a generation to prove its ability and prowness to overcome the limitations set by Einstein.

    Do I believe he understood this?

    Most assuredly so, for such conversation and thought experiments would have never been inrtroduced in such a forum, as to the require greater participation of thinkers to succeed. Some even to their death, still felt Eisntein's challenge, and we have a wonderful area of developement that has moved our visions to wonderful interactive feature of "gluonic perceptions."

    I believe also that Lee Smolin, from his current work, is to instill and gather strong leaders to focus in a direction that Lubos has spotted, as a signature of Lee Smolin ways. To discern the quality and direction, before gravitonic abilities are ever encountered.

    So yes such attempts are interesting, in that we see Glast detrmination as viable pathways to solving the understanding of the world around us and even going to great lengths, to move these consderation down to the level we might seee in such energetic features where such gravities might have exemplied a measured interactive feature like those of the Calorimetric design.

    So the challenge was given to both sides of the camps to give us a way inwhich to see how such a challenge could measure progress? Is it not here, that such a stance holds each other accountable?

    Lee Smolins ways expermentally are driven, even as the world of Strings are driven to bring perspective to the engagement, of the "way in which we see?" Careful challeneges to the interpretation, that such ideas are held within the scope of the Calorimentric view and all the while, the challenge has been a puzzle to that "missing energy" going someplace?

    Where is this if such a boundary has been understood and the puzzle offered for introspection, that each other wants the other to understand it's limitations?

    So now we have the place in which such a challenge should make itself known and we have the likes of Cern's delivery on microstate blackhole production, to have found it's associative feature in how we see interactive features can happen all around us without cern? >John Ellis is careful to draw these distinctions for us.

    Do we have Proof of this Missing Energy? If the answer is yes, then the issue has not been resolved?

    Microstates and Gravity


    Strominger: That was the problem we had to solve. In order to count microstates, you need a microscopic theory. Boltzmann had one–the theory of molecules. We needed a microscopic theory for black holes that had to have three characteristics: One, it had to include quantum mechanics. Two, it obviously had to include gravity, because black holes are the quintessential gravitational objects. And three, it had to be a theory in which we would be able to do the hard computations of strong interactions. I say strong interactions because the forces inside a black hole are large, and whenever you have a system in which forces are large it becomes hard to do a calculation.



    I was scanning over at Sean Carroll's blog and noticed his current article. It seems he is doing some kind of exorcism?:)

    Entropy and intelligence


    Consider the following system: a rectangular container filled part way with tiny spheres, some of them made of glass and some of brass. All the spheres have equal size, but the brass ones are heavier than the glass ones. Okay, now please tell me which of these configurations has the lowest entropy (or highest order, or greatest complexity, or whatever it is that you think only intelligence can bring into existence):


    Now what was appealing to me here is the question of arrangement, and how chaotic systems might have been ruled by other consequences? Like gravity. So troubled by the analogy presented and distancing myself from some satanic feature of intelligent dsign, I wonder, what is going on here?


    The animation shows schematically the behavior of the gas molecules in the presence of a gravitational field. We can see in this figure that the concentration of molecules at the bottom of the vessel is higher than the one at the top of the vessel, and that the molecules being pushed upwards fall again under the action of the gravitational field.


    Now if I was to wonder about what would govern these thoughts, then indeed the question is raised that such intelligence is governed by a organizational ability that evolved from a better understanding of these graviational influences?

    I am a junior here so the idea that such a exorcism would have been dispelled in this attempted has me wondering. Is there some greater design here in elminating the abilities of capable good thinking people and spooky actions, that have defied explanation?

    A nice airplane ride is always fruitful to higher forms of thinking here? Time clocks, still exemplify some characteristics on molecular arangements? As well as Einstein and liethe impulsive qualites that such characters appeal to the scolastic heroes of our time, we are drawn by some inexplicable force to wonder about natures way?

    Self Organization of Matter

    Likewise, if the very fabric of the Universe is in a quantum-critical state, then the "stuff" that underlies reality is totally irrelevant-it could be anything, says Laughlin. Even if the string theorists show that strings can give rise to the matter and natural laws we know, they won't have proved that strings are the answer-merely one of the infinite number of possible answers. It could as well be pool balls or Lego bricks or drunk sergeant majors.

    Blaise Pascal


    Blaise Pascal (June 19, 1623 – August 19, 1662)

    Born in Clermont-Ferrand (France), the young Pascal was introduced to mathematics and physics by his father. So precocious was his talent in these disciplines that he published his innovative Essai pour les coniques [Essay on conics] in 1632, at only sixteen. In 1631, he moved to Paris, where he frequented the intellectual circle of Marin Mersenne (1588-1648)—a forum for the discussion of the most topical scientific and philosophical questions. In 1644, he became interested in the technological aspects of scientific research, devising a calculating machine that could perform additions and subtractions. In 1646, he conducted path-breaking research on the vacuum and fluid dynamics. He devoted two major works to fluids—Équilibre des liqueurs [Equilibrium of liquids] and De la pesanteur de la masse d'air [On the weight of the mass of air]—written in 1651-1654, but not published until 1663. In 1653-1654, he composed some brief but seminal papers on combinatory calculus, infinitesimal calculus, and probability. Pascal repeated Evangelista Torricelli's experiment, using various liquids and containers of different shapes and sizes. This research, in addition to the publication of Expériences nouvelles touchant le vide [New experiments on the vacuum], culminated in the famous experiment performed in 1648 on the Puy-de-Dôme, in which he demonstrated that atmospheric pressure lessens with an increase in altitude.

    In parallel with his scientific pursuits, Pascal displayed a deep and abiding concern with religious and moral issues. In his youth, he espoused Jansenism and began to frequent the Port-Royal group. These contacts form the background to the Lettres provinciales (1656-1657) and the Pensées (published posthumously in 1670).


    I had to lay this out before I continued to speak to the world Lubos motl directs us too. In a way, these mathematical pursuance and comprehensions, are revealing, when they speak to the greater probability of discovering the root systems mathematically as well as philosophically. Cases in point, about compaction scenarios are self explanatory when it comes to energy determination and particle reductionism . This relationship to idealization of supergravity, points thinking to a vast overall comprehension suited to the culminations of a model employed such as string theory?

    But back to the point of focus here.

    Earlier derivation of Pascal's thinking, "are roads that even he was lead too," that we have this fine way in which to speak about the root of mathematical initiative, and these roots leading to mathematical forays into the natural world.


    Diagram 6. Khu Shijiei triangle, depth 8, 1303.

    The so called 'Pascal' triangle was known in China as early as 1261. In '1261 the triangle appears to a depth of six in Yang Hui and to a depth of eight in Zhu Shijiei (as in diagram 6) in 1303. Yang Hui attributes the triangle to Jia Xian, who lived in the eleventh century' (Stillwell, 1989, p136). They used it as we do, as a means of generating the binomial coefficients.

    It wasn't until the eleventh century that a method for solving quadratic and cubic equations was recorded, although they seemed to have existed since the first millennium. At this time Jia Xian 'generalised the square and cube root procedures to higher roots by using the array of numbers known today as the Pascal triangle and also extended and improved the method into one useable for solving polynomial equations of any degree' (Katz, 1993, p191.)



    See I am somewhat starting with a disadvantage because buried in my head is the reasons for describing math more then it's intuitionist valuation in computer generated idealizations. It all of a sudden brings into perspective a deeper sense of the possibilities and probabilities?

    Here I am quickly reminded of Gerard t'hooft, and the thinking, about reductionistic views of information in computerized versions. Philosophically how can we have reduced information to such sizes and find the world a much more complex place. Would we not realize that such intuitionist attempts too have to undergo revisions as well?

    A Short History of Probability


    "A gambler's dispute in 1654 led to the creation of a mathematical theory of probability by two famous French mathematicians, Blaise Pascal and Pierre de Fermat. Antoine Gombaud, Chevalier de Méré, a French nobleman with an interest in gaming and gambling questions, called Pascal's attention to an apparent contradiction concerning a popular dice game. The game consisted in throwing a pair of dice 24 times; the problem was to decide whether or not to bet even money on the occurrence of at least one "double six" during the 24 throws. A seemingly well-established gambling rule led de Méré to believe that betting on a double six in 24 throws would be profitable, but his own calculations indicated just the opposite.


    Shall we quickly advantage to a age of reason where understand well the beginnings of mathematical systems and lead into Boltzman? But before I do that, I wanted to drawn attention to the deeper significance of this model appreciation.

    Discovering Patterns



    While we get some understanding here of what Pascal's triangle really is you learn to sense the idea of what culd have ever amounted to expressionand this beginning? Did nature tell us it will be this way, or some other form of expression?

    So overall the probability of expressionism has devloped the cncptual basis as arriving from soem place and not nothing. True enough, what is this basis of existance that we would have a philosphical war between the background versus non background to end up in stauch positional attitudes about how one should approach science here?

    So to me, I looked for analogies again to help me understand this idea of what could have ever arisen out of string theory that conceptually mad esense . Had a way in which to move forward, with predictable features? Is their sucha things dealing with the amount of information that we have in reductionsitic views. These views had to come to a end, and I will deal with this later.

    Of course now such idealization dealng with probabilties off course, forces me to contend with what has always existed and helps deal with this cyclcial nature. You have to assume soemthing first. That will be the start of the next post.

    But back to finishing this notion of probability and how the natural order of the universe would have said folow this way young flower, that we coud seen expansionism will not only be detailled in the small things, but will be the universe, in it's expression as well?


    The Pinball Game


    The result is that the pinball follows a random path, deflecting off one pin in each of the four rows of pins, and ending up in one of the cups at the bottom. The various possible paths are shown by the gray lines and one particular path is shown by the red line. We will describe this path using the notation "LRLL" meaning "deflection to the left around the first pin, then deflection right around the pin in the second row, then deflection left around the third and fourth pins".

    So what has happened here to force us to contend with certain issues that the root numbers of all things could have manifested, and said, "nature shall be this way?"


    Ludwig Boltzmann (1844-1906)

    In 1877 Boltzmann used statistical ideas to gain valuable insight into the meaning of entropy. He realized that entropy could be thought of as a measure of disorder, and that the second law of thermodynamics expressed the fact that disorder tends to increase. You have probably noticed this tendency in everyday life! However, you might also think that you have the power to step in, rearrange things a bit, and restore order. For example, you might decide to tidy up your wardrobe. Would this lead to a decrease in disorder, and hence a decrease in entropy? Actually, it would not. This is because there are inevitable side-effects: whilst sorting out your clothes, you will be breathing, metabolizing and warming your surroundings. When everything has been taken into account, the total disorder (as measured by the entropy) will have increased, in spite of the admirable state of order in your wardrobe. The second law of thermodynamics is relentless. The total entropy and the total disorder are overwhelmingly unlikely to decrease


    So what has happened that we see the furthest reaches of our universe? Such motivation having been initiated, had been by some motivator. Shall you call it intelligent design(God) when it is very natural process that had escaped our reasoning minds?

    So having reached it's limitation(boundry) this curvature of the universe, has now said, "such disorder having reached it's reductionistic views has now found it's way back to the beginning of this universe's expression? It's cyclical nature?

    This runs "contray to the arrow of time," in that these holes, have somehow fabricated form in another mode of thought that represents dimensional values? This basis from which to draw from, had to have energy valuations missing fromthe original expression? It had to have gone some place. Where is that?

    But I have digressed greatly, to have missed the point of Robert Lauglin's principals, "of building blocks or drunk sergeant majors", and what had been derived from the energy in it's beginning? To say the complexity of those things around us had to returned our thinking back to some concept that was palitable.

    Why the graduation to ISCAP, and Lenny's new book, is the right thing to do

    (LEONARD SUSSKIND:) What I mostly think about is how the world got to be the way it is. There are a lot of puzzles in physics. Some of them are very, very deep, some of them are very, very strange, and I want to understand them. I want to understand what makes the world tick. Einstein said he wanted to know what was on God's mind when he made the world. I don't think he was a religious man, but I know what he means.

    The thing right now that I want to understand is why the universe was made in such a way as to be just right for people to live in it. This is a very strange story. The question is why certain quantities that go into our physical laws of nature are exactly what they are, and if this is just an accident. Is it an accident that they are finely tuned, precisely, sometimes on a knife's edge, just so that the world could accommodate us?

    The Holographical Mapping of the Standard Model onto the Blackhole Horizon

    New paper that came out yesterday written by Gerard 't Hooft

    Interactions between outgoing Hawking particles and ingoing matter are determined by gravitational forces and Standard Model interactions. In particular the gravitational interactions are responsible for the unitarity of the scattering against the horizon, as dictated by the holographic principle, but the Standard Model interactions also contribute, and understanding their effects is an important first step towards a complete understanding of the horizon’s dynamics. The relation between in- and outgoing states is described in terms of an operator algebra. In this paper, the first of a series, we describe the algebra induced on the horizon by U(1) vector fields and scalar fields, including the case of an Englert-Brout-Higgs mechanism, and a more careful consideration of the transverse vector field components.


    But before I entertain this idea, I wanted to gain some perspective. I was immediately struck by something here that changes the way we have been doing things? Recognizing the blackhole evaporation and standard model production, we are saying that indeed these things already existed in the horizon?

    Would M theory have then found it's experimental counterpart? The Bose Nova and Jet idea from collapsing bubbles has been part of the vision I speculated in what Heisenberg saw in the geometrodynamics of a nuclear explosion. See, not only were we detonating a nuclear reaction(gravitational collapse), but we were doing something beyond the perception, by going to the heart of these particle collisions.

    What makes it diffuclt for me is that having seen the blackhole dynamics in relation to bubble technlogies, that I like to use as analogies, relate too, and contain the elements of the standard model without ever entering the blackhole? How is this possible and still see the three blane collapse of the blackhole here?

    Dimensional Reduction in Quantum Gravity by Gerard 't Hooft


    The requirement that physical phenomena associated with gravitational collapse should be duly reconciled with the postulates of quantum mechanics implies that at a Planckian scale our world is not 3+1 dimensional. Rather, the observable degrees of freedom can best be described as if they were Boolean variables defined on a two-dimensional lattice, evolving with time. This observation, deduced from not much more than unitarity, entropy and counting arguments, implies severe restrictions on possible models of quantum gravity. Using cellular automata as an example it is argued that this dimensional reduction implies more constraints than the freedom we have in constructing models. This is the main reason why so-far no completely consistent mathematical models of quantum black holes have been found.

    Essay dedicated to Abdus Salam.


    Gerard "t Hooft:No 'Quantum Computer' will ever be able to out perform a 'scaled up classical computer.'

    Holding onto the sanity of why such computerization program will run into difficulties, has not undermined the position to included and create opportunities for seeing what is happening at such reductionistic levels? To have wondered, will we gain a dynamcial visulaization of what is happening within the context of the universe as it came into being?

    With more computer power, scientists can also include more elements of the Earth's climate system, such as the oceans, the atmosphere, their chemistry and the carbon cycle.

    This should make forecasts of future temperature rises more reliable. Keiko Takahashi, who works at the Earth Simulator Centre, says they have already carried out several experiments that look 50 years ahead.



    There is difficulties with doing this, and like LIGO or a SEti work in progress, how shall this information allows us to see the interactions in a consistent model? So dealing with these difficulties has been part of Gerard 't Hoofts analysis to see that others too, work hard to deal with issues of information paradox?

    Part of this difficulty in computerized model application, would have been transfer rates of information from such quantum levels. Lubos gives some insight here. Although it has been very nice that such visualization techiques could be applied to this data transfer, from what we understand of particle reductionsism. Within context of the larger universe, how detailed shall has our observations become of the world around us?


    These images contrast the degree of interaction and collective motion, or "flow," among quarks in the predicted gaseous quark-gluon plasma state (Figure A, see mpeg animation) vs. the liquid state that has been observed in gold-gold collisions at RHIC (Figure B, see mpeg animation). The green "force lines" and collective motion (visible on the animated version only) show the much higher degree of interaction and flow among the quarks in what is now being described as a nearly "perfect" liquid.

    The goal of the Large Hadron Collider (LHC) is to link roughly 6,000 scientists so they can perform large-scale experiments and simulations to help the world better understand subatomic particles. The grid will ultimately link more than 200 research institutions.

    "This service challenge is a key step on the way to managing the torrents of data anticipated from the LHC," Jamie Shiers, manager of the service challenges at CERN, said in a statement. "When the LHC starts operating in 2007, it will be the most data-intensive physics instrument on the planet, producing more than 1,500 megabytes of data every second for over a decade."


    Gerard 't Hooft recognized this problem and when we see such scattering ideas from blackhole standard model production particles, how shall we see this event in terms of what is sent back for examination? It would mean considering the context of Gerard's paper there is no information loss? No missing energy events?

    Thus the consistent model frame, from blackhole production underlying framework would disavow any ideas relating to energy in and energy out imbalance held in context of gravitonic production as part of the standard model production? The horizon area would become a balanced view?

    Using the ideas of Clementine and the graduation to Grace, it seemed that I was leading to a good comprehensive view of the bubble technicalities as they contained the missing energy, but moving too "this view of Gerard's" might endanger how we approximate the whole view of this missing energy, with the easy removal of that missing energy scenario? Would this be consistent with the overall encompassed view that the grvaiton has emerged from the extension of this standard model to say oh, it's okay we can remove this and fnd comfort with the existing framework without other contentions issues like missing energy to deal with this?

    Do we have Proof of this Missing Energy? If the answer is yes, then the issue has not been resolved?

    Emergence= Phase Transitions of Symmetry?

    Witten said:
    One thing I can tell you, though, is that most string theorist's suspect that spacetime is a emergent Phenomena in the language of condensed matter physics.





    Part of the difficulty was realizing that the end result of a current depiction of the universe, and the reality around us now, had led us to assumption discrete manifestations of a earlier prospective universe. From that early universe, until now.

    In 1877 Boltzmann used statistical ideas to gain valuable insight into the meaning of entropy. He realized that entropy could be thought of as a measure of disorder, and that the second law of thermodynamics expressed the fact that disorder tends to increase. You have probably noticed this tendency in everyday life! However, you might also think that you have the power to step in, rearrange things a bit, and restore order. For example, you might decide to tidy up your wardrobe. Would this lead to a decrease in disorder, and hence a decrease in entropy? Actually, it would not. This is because there are inevitable side-effects: whilst sorting out your clothes, you will be breathing, metabolizing and warming your surroundings. When everything has been taken into account, the total disorder (as measured by the entropy) will have increased, in spite of the admirable state of order in your wardrobe. The second law of thermodynamics is relentless. The total entropy and the total disorder are overwhelmingly unlikely to decrease

    Now the apparent contradiction is to understand that when the views are taken to those small spaces, reductionistic features of a discrete nature have forced us to consider the building blocks of matter, but at the same time, something else makes it's way into our views that would have been missed had you not realized that the space contains a lot of energy?

    To build this symmetrical and simple model of elegance, you needed some model, some framework in which to consider the distant measure here would be ultimately derived from the blackhole and it's dynamics? The simple solution would help you recognize that any massless particle emitted from this state, would automatically signal the closest source of consideration that any of us could have imagined.

    Even Smolin, recognized the Glast determinations. Why I have said, that Smolin could not have gotten any closer then what is surmised from the origination of emission from the blackhole consideration?

    The Arrow of Time


    Rudolf Julius Emanuel Clausius


    There is but one kind of entropy change. Entropy change is due to energy dispersal to, from, or within a system (as a function of temperature.), measured by microstate change: S = kB ln [microstates final / microstates initial ].


    I should back up here and mentioned that Peter Woit seems to be coming out in the open and explaining somethings that have been not so clear before?

    Perter Woit:
    Penrose also carefully lays out areas in which his point of view differs from the general consensus of most theoretical physicists. An example is his emphasis on the importance for cosmology of understanding why the universe had such low entropy at the Big Bang


    What is strange today that with this thought on the subject of entropy.

    Lubos Motl:
    This is what allows the early gas to clump (and seemingly create a more order state) without violating the 2nd law of thermodynamics: the gravitational entropy overcomensates the decrease of the entropy.

    OK, so why was the beginning of the Universe a low-entropy state? The best explanation we have is inflation. It simply explodes the size of the Universe. During inflation, the total entropy of the Universe grows, but much more slowly than how it would grow otherwise, without inflation
    .


    if one did not understand the early universe consideration here, and the idealization of supersymmetry, could we have found a association to low orders of entropy since this early time would have been very topologically considered and part of a continuum?

    Entropy and the second law of thermodynamics

    Entropy is no mystery or complicated idea. Entropy is merely the way to measure the energy that spreads out in a process (as a function of temperature). What's complicated about that? Entropy change, S, measures how much energy is spread out in a system, or how spread out is the energy of a system (both always involving T). The first example in our text was melting ice to water at 273 K where S = q/T. So, in that equation, it's easy to see that q (the enthalpy of fusion) is how much "heat" energy was spread out in the ice to change it to water. What's the big deal?


    Update: Reading Peter Woit's blog today he linked Sean Carroll's "Arrow of Time article," so I thought it most apropriate to link it from here as well, since I am on the topic.


    Sean Carroll:
    Jennie and I do the following thought experiment -- if it weren't for inflation, what would be a "natural" state for the universe to be in? Different people have addressed this question, with different answers; Roger Penrose, for example, has suggested that it would be a lumpy universe full of black holes. Our answer is almost exactly the opposite -- the only natural state is empty space. This is basically because gravity makes everything unstable, and the entropy of any given configuration can always be increased by just expanding the universe by a huge factor. Sure, black holes will form, but they will ultimately evaporate away. If you let the universe evolve forever, it will ultimately get emptier and emptier (generically).

    Quantum Microstates: Gas Molecules in the Presence of a Gravitational Field

    Andy Strominger:
    This was a field theory that lived on a circle, which means it has one spatial dimension and one time dimension. We derived the fact that the quantum states of the black hole could be represented as the quantum states of this one-plus-one dimensional quantum field theory, and then we counted the states of this theory and found they exactly agreed with the Bekenstein-Hawking entropy.


    I do not know of many who could not have concluded that microstates would have been something of an issue, as one recognizes this focus towards cosmological considerations. One aspect of Einstein’s general relativity, helped us recognize the value of gravitation that is extremely strong in situations where energy values are climbing. We had to look for these conditions and work them out?



    Strominger: That was the problem we had to solve. In order to count microstates, you need a microscopic theory. Boltzmann had one–the theory of molecules. We needed a microscopic theory for black holes that had to have three characteristics: One, it had to include quantum mechanics. Two, it obviously had to include gravity, because black holes are the quintessential gravitational objects. And three, it had to be a theory in which we would be able to do the hard computations of strong interactions. I say strong interactions because the forces inside a black hole are large, and whenever you have a system in which forces are large it becomes hard to do a calculation.

    The old version of string theory, pre-1995, had these first two features. It includes quantum mechanics and gravity, but the kinds of things we could calculate were pretty limited. All of a sudden in 1995, we learned how to calculate things when the interactions are strong. Suddenly we understood a lot about the theory. And so figuring out how to compute the entropy of black holes became a really obvious challenge. I, for one, felt it was incumbent upon the theory to give us a solution to the problem of computing the entropy, or it wasn't the right theory. Of course we were all gratified that it did.


    If we did not have some way in which to move our considerations to the energy states that existed in the beginning of this universe what other measures would you use? How would you explain a cyclical model that Neil Turok and Steinhardt talked about and created for us?

    Is this a predictive feature of our universe that had to have some probablity of expression and mathematically, if one wanted some framework, why not throw all things to the wind and say, Pascal's triangle will do?:)

    The animation shows schematically the behavior of the gas molecules in the presence of a gravitational field. We can see in this figure that the concentration of molecules at the bottom of the vessel is higher than the one at the top of the vessel, and that the molecules being pushed upwards fall again under the action of the gravitational field.

    One had to have some beginning with which to understand what could have emerged from such energy configurations. If such energies are concentrated and found to bring us to the supersymmetrical values assigned on that brane, then how would cooling functions of the CMB have figured a direct result would be expressive of those same events? Was there no way to measure chaoticness. Maybe it was all Fool’s Gold?:)

    Fool's Gold



    Ludwig Boltzmann
    (1844-1906)

    In 1877 Boltzmann used statistical ideas to gain valuable insight into the meaning of entropy. He realized that entropy could be thought of as a measure of disorder, and that the second law of thermodynamics expressed the fact that disorder tends to increase. You have probably noticed this tendency in everyday life! However, you might also think that you have the power to step in, rearrange things a bit, and restore order. For example, you might decide to tidy up your wardrobe. Would this lead to a decrease in disorder, and hence a decrease in entropy? Actually, it would not.

The second law of thermodynamics is relentless. The total entropy and the total disorder are overwhelmingly unlikely to decrease



    However, don't be fooled! The charm of the golden number tends to attract kooks and the gullible - hence the term "fool's gold". You have to be careful about anything you read about this number. In particular, if you think ancient Greeks ran around in togas philosophizing about the "golden ratio" and calling it "Phi", you're wrong. This number was named Phi after Phidias only in 1914, in a book called _The Curves of Life_ by the artist Theodore Cook. And, it was Cook who first started calling 1.618...the golden ratio. Before him, 0.618... was called the golden ratio! Cook dubbed this number "phi", the lower-case baby brother of Phi.

    How much wiser are we with the understanding that Curlies Gold told us much about what to look for in that One Thing?



    The result is that the pinball follows a random path, deflecting off one pin in each of the four rows of pins, and ending up in one of the cups at the bottom. The various possible paths are shown by the gray lines and one particular path is shown by the red line. We will describe this path using the notation "LRLL" meaning "deflection to the left around the first pin, then deflection right around the pin in the second row, then deflection left around the third and fourth pins".


    So, what is the value of PI, if a "point" on the brane holds previous information about the solid things we see in our universe now? Have we recognized the momentum states, represented by the KK Tower and the value of 1R as it arises from the planck epoch?

    The statistical sense of Maxwell distribution can be demonstrated with the aid of Galton board which consists of the wood board with many nails as shown in animation. Above the board the funnel is situated in which the particles of the sand or corns can be poured. If we drop one particle into this funnel, then it will fall colliding many nails and will deviate from the center of the board by chaotic way. If we pour the particles continuously, then the most of them will agglomerate in the center of the board and some amount will appear apart the center. After some period of time the certain statistical distribution of the number of particles on the width of the board will appear. This distribution is called normal Gauss distribution (1777-1855) and described by the following expression:

    Plato's Cave and Heisenberg, 21st Century with Witten

    Breaking Symmetry

    Here I sit in Brane world and the idea of "Pants" reaching different dimenisons seems intrigueing to me. Far beyond the views that one see from the light shining, from the open mouth of the cave, some far reaching ideas are manfesting into the world we see today. How weak then, the gravity in a world that has become solidly defined? Who entropic disorder has spoken to this solid and that solid, and from the light it all began?


    Entropic Systems and Black Holes
    The laws of thermodynamics, including the fact that heat energy will never flow from a colder to a hotter location, support the belief in entropy: in a closed system, energy will eventually wind down to zero

    But wait by its very action, it's collapse, the supersymmetrical reality is envisioned as heat begins to generate. So we have within this universe, a method by which moments that had been defined in our beginnings, might now find itself expressed agin in the cosmo(a closed system?)


    For me if we had UNDERSTOOD THE TRUE EXPLANATION OF THE STATE OF THE UNIVERSE FROM SUPERSYMMETRICAL BEGINNINGS, THEN SUCH A VIEW FROM THE CAVE WOULD HAVE DEFINED THESE MOMENTs FOR ME, AS PLATO IN SOLID FORMS THAT CRYSTALs WOULD HAVE DESIgen according to the five elements?



    And now, I said, let me show in a figure how far our nature is enlightened or unenlightened: --Behold! human beings living in a underground den, which has a mouth open towards the light and reaching all along the den; here they have been from their childhood, and have their legs and necks chained so that they cannot move, and can only see before them, being prevented by the chains from turning round their heads. Above and behind them a fire is blazing at a distance, and between the fire and the prisoners there is a raised way; and you will see, if you look, a low wall built along the way, like the screen which marionette players have in front of them, over which they show the puppets.

    Plato's Republic

    [Glaucon]True, he said; how could they see anything but the shadows if they were never allowed to move their heads?

    [Socrates]And of the objects which are being carried in like manner they would only see the shadows?

    [Glaucon]Yes, he said.
