On Gauss's Day of Reckoning

A famous story about the boy wonder of mathematics has taken on a life of its own -Brian Hayes



Illustration by Theoni Pappas

In a fanciful drawing done in the manner of a woodcut, the young Carl Friedrich Gauss receives instruction in arithmetic from the schoolmaster J. G. Büttner. As the story goes, Gauss was about to give Büttner a lesson in mathematical creativity.


To me the historical significance of this research is important to me. People could chastise me for saying that the research I do has no quality, then what should be assumed with scientific credentials? Still the romance I have for such abstractions and development of thinking is important just the same. It is about creativity to me, and looking back to the ingenuity of thought, is something I can see in everyone. One doesn't have to consider them self less then, just by being the student that would solve the problem, while insight and acute perception, might have been revealed in one who could throw down the slate the quickest.

The story is fascinating tome on a lot of different levels and to tracking down the essence of what we see passed from one hand to another, and how this ambiguity might creep in and additions make there way for added material.

I understand this in our response to writing science, with what language is supposed to be. Sure talk about chinese , Italian, Latin of ole, and we want to know what the truest expression of the language should be?

Of course this is the responsibility of math, that a common basis be found, between all languages, that the source would have described it so abstract/yet closest to the center of the circle) that all would understand and could work the abstract nature of this math.

I feel guilty, that I cannot contribute so well to this math language, that I strive to listen very good to the concepts espoused, as close as possible to the development of this Algebraic way of seeing.

Yes, it is as important, as the geometrical seeing that it be inherent in the way things abstractly can be seen. That both would have supported the continued work fo science.

Mine then is the student's plight in a vast world that I exist away from, yet, try and stay as close as I can to learn.

Do I sanction everyones abilities away from this in character, is no less then the character I assume, and has been treated. That respect be given, might have found the truer calling of sharing the insights, be as truthful as possible. We should all strive to this of course.

What is Swirling in my Mind

As I lay there many things float through my mind about how we are seeing things now.

So the article above sparked some thoughts here about Sylvestor surfaces and B field understandings, that also included Lagrangian perspective along with WMAP polarization mapping. All these things seem so disconnected?

I keep finding myself trying to wrap all of this in a gravitational perspective as it should , no less important then gauss contributions, hidden for a time, while the student of his brings the perspective for us all to see. So how familiar is protege as Riemann that his Hypothesis is so much the like of the numbers apparent, as in the youthful gaze of the student challenged.

Computer Language and Math Joined from Artistic Impressionism?

Most people think of "seeing" and "observing" directly with their senses. But for physicists, these words refer to much more indirect measurements involving a train of theoretical logic by which we can interpret what is "seen."- Lisa Randall




Cubist Art: Picasso's painting 'Portrait of Dora Maar'
Cubist art revolted against the restrictions that perspective imposed. Picasso's art shows a clear rejection of the perspective, with women's faces viewed simultaneously from several angles. Picasso's paintings show multiple perspectives, as though they were painted by someone from the 4th dimension, able to see all perspectives simultaneously.


Sean from Cosmic Variance writes his opening post by including the title, "The language of Science".


I would have said maths as well, yet, as a Layman there is much for me to learn.


THOMAS BANCHOFF has been a professor of mathematics at Brown University in Providence, Rhode Island, since 1967. He has written two books and fifty articles on geometric topics, frequently incorporating interactive computer graphics techniques in the study of phenomena in the fourth and higher dimensions


The marriage between computer and math language(Banchoff) I would say would be important from the prospective of displaying imaging, seen in the development of abstract language as used in numerical relativity? Accummalated data gained from LIGO operations. Time variable measures?



My first demonstration was with a Calabi Yau model of the torso. Visually seeing this way, helped to progress understanding. The transferance from the math structure to imaging in computer, to me, seemed very hard thing to do.


Alain Connes

Where a dictionary proceeds in a circular manner, defining a word by reference to another, the basic concepts of mathematics are infinitely closer to an indecomposable element", a kind of elementary particle" of thought with a minimal amount of ambiguity in their definition.



If the math is right, the "concepts spoken," will be right also?



How such reductionism is held to the values of science, is seen in the work of the calorimeters. Glast and LHC designs give introspective views of how fine our perspective is being shaped. Can we see the underlying imaging as a toll, respective of reductionism as seeing the dynamical and geoemtrical background to all events measured? LIGO in data accumulation, describing the infomration released into the bulk perspective.

Toroidal_LHC_ApparatuS

In the theory of relativity, momentum is not proportional to velocity at such speeds.) Thus high-momentum particles will curve very little, while low-momentum particles will curve significantly; the amount of curvature can be quantified and the particle momentum can be determined from this value.

Hyperbolic Geometry and it's Rise

Omar Khayyám the mathematician(6 april 2006 Wikipedia)

He was famous during his lifetime as a mathematician, well known for inventing the method of solving cubic equations by intersecting a parabola with a circle. Although his approach at achieving this had earlier been attempted by Menaechmus and others, Khayyám provided a generalization extending it to all cubics. In addition he discovered the binomial expansion, and authored criticisms of Euclid's theories of parallels which made their way to England, where they contributed to the eventual development of non-Euclidean geometry.


Giovanni Girolamo Saccheri(6 April 2006 Wikipedia)

Saccheri entered the Jesuit order in 1685, and was ordained as a priest in 1694. He taught philosophy at Turin from 1694 to 1697, and philosophy, theology, and mathematics at Pavia from 1697 until his death. He was a protege of the mathematician Tommaso Ceva and published several works including Quaesita geometrica (1693), Logica demonstrativa (1697), and Neo-statica (1708).


Of course the question as to "Victorian" was on mind. Is non-euclidean held to a time frame, or not?

Victorian Era(wikipedia 6 April 2006)

It is often defined as the years from 1837 to 1901


Time valuations are being thought about here. In regards too, non euclidean geometry and it's rise. Shows, many correlations within that time frame. So that was suprizing, if held to a context of the victorian socialogical time frame. But we know this statement is far from the truth?


Seminar on the History of Hyperbolic Geometry, by Greg Schreiber

We began with an exposition of Euclidean geometry, first from Euclid's perspective (as given in his Elements) and then from a modern perspective due to Hilbert (in his Foundations of Geometry). Almost all criticisms of Euclid up to the 19th century were centered on his fifth postulate, the so-called Parallel Postulate.The first half of the course dealt with various attempts by ancient, medieval, and (relatively) modern mathematicians to prove this postulate from Euclid's others. Some of the most noteworthy efforts were by the Roman mathematician Proclus, the Islamic mathematicians Omar Khayyam and Nasir al-Din al-Tusi, the Jesuit priest Girolamo Sacchieri, the Englishman John Wallis, and the Frenchmen Lambert and Legendre. Each one gave a flawed proof of the parallel postulate, containing some hidden assumption equivalent to that postulate. In this way properties of hyperbolic geometry were discovered, even though no one believed such a geometry to be possible.


History (wikipedia 6 April 2006)

Hyperbolic geometry was initially explored by Giovanni Gerolamo Saccheri in the 1700s, who nevertheless believed that it was inconsistent, and later by János Bolyai, Karl Friedrich Gauss, and Nikolai Ivanovich Lobachevsky, after whom it is sometimes named.

On Gauss's Mountain

You must understand that any corrections necessary are appreciated. The geometrical process spoken too here must be understood in it's historical development to undertand, how one can see differently.

Euclidean geometry, elementary geometry of two and three dimensions (plane and solid geometry), is based largely on the Elements of the Greek mathematician Euclid (fl. c.300 B.C.). In 1637, René Descartes showed how numbers can be used to describe points in a plane or in space and to express geometric relations in algebraic form, thus founding analytic geometry, of which algebraic geometry is a further development (see Cartesian coordinates). The problem of representing three-dimensional objects on a two-dimensional surface was solved by Gaspard Monge, who invented descriptive geometry for this purpose in the late 18th cent. differential geometry, in which the concepts of the calculus are applied to curves, surfaces, and other geometrical objects, was founded by Monge and C. F. Gauss in the late 18th and early 19th cent. The modern period in geometry begins with the formulations of projective geometry by J. V. Poncelet (1822) and of non-Euclidean geometry by N. I. Lobachevsky (1826) and János Bolyai (1832). Another type of non-Euclidean geometry was discovered by Bernhard Riemann (1854), who also showed how the various geometries could be generalized to any number of dimensions.


These tidbits, would have been evidence as projects predceding as "towers across valleys" amd "between mountain measures," to become what they are today. Allows us to se in ways that we are not used too, had we not learnt of this progression and design that lead from one to another.


8.6 On Gauss's Mountains

One of the most famous stories about Gauss depicts him measuring the angles of the great triangle formed by the mountain peaks of Hohenhagen, Inselberg, and Brocken for evidence that the geometry of space is non-Euclidean. It's certainly true that Gauss acquired geodetic survey data during his ten-year involvement in mapping the Kingdom of Hanover during the years from 1818 to 1832, and this data included some large "test triangles", notably the one connecting the those three mountain peaks, which could be used to check for accumulated errors in the smaller triangles. It's also true that Gauss understood how the intrinsic curvature of the Earth's surface would theoretically result in slight discrepancies when fitting the smaller triangles inside the larger triangles, although in practice this effect is negligible, because the Earth's curvature is so slight relative to even the largest triangles that can be visually measured on the surface. Still, Gauss computed the magnitude of this effect for the large test triangles because, as he wrote to Olbers, "the honor of science demands that one understand the nature of this inequality clearly". (The government officials who commissioned Gauss to perform the survey might have recalled Napoleon's remark that Laplace as head of the Department of the Interior had "brought the theory of the infinitely small to administration".) It is sometimes said that the "inequality" which Gauss had in mind was the possible curvature of space itself, but taken in context it seems he was referring to the curvature of the Earth's surface.


One had to recognize the process that historically proceeded in our overviews "to non-euclidean perspectives," "geometrically enhanced" through to our present day headings, expeirmentallly.

Michelson interferometer(27 Mar 2006 wikipedia)

Michelson interferometer is the classic setup for optical interferometry and was invented by Albert Abraham Michelson. Michelson, along with Edward Morley, used this interferometer for the famous Michelson-Morley experiment in which this interferometer was used to prove the non-existence of the luminiferous aether. See there for a detailed discussion of its principle.

But Michelson had already used it for other purposes of interferometry, and it still has many other applications, e.g. for the detection of gravitational waves, as a tunable narrow band filter, and as the core of Fourier transform spectroscopy. There are also some interesting applications as a "nulling" instrument that is used for detecting planets around nearby stars. But for most purposes, the geometry of the Mach-Zehnder interferometer is more useful.


A quick summation below leads one onto the idea of what experimental validation has done for us. Very simply, the graduation of interferometer design had been taken to astronomical proportions?



Today the Count expands on this for us by showing other information on expeirmental proposals. How fitting that this historical drama has been shown here, in a quick snapshot. As well the need for understanding the "principal inherent" in the project below.

VLBI is a geometric technique: it measures the time difference between the arrival at two Earth-based antennas of a radio wavefront emitted by a distant quasar. Using large numbers of time difference measurements from many quasars observed with a global network of antennas, VLBI determines the inertial reference frame defined by the quasars and simultaneously the precise positions of the antennas. Because the time difference measurements are precise to a few picoseconds, VLBI determines the relative positions of the antennas to a few millimeters and the quasar positions to fractions of a milliarcsecond. Since the antennas are fixed to the Earth, their locations track the instantaneous orientation of the Earth in the inertial reference frame. Relative changes in the antenna locations from a series of measurements indicate tectonic plate motion, regional deformation, and local uplift or subsidence.

    Bose- Einstein Condensates

    ESI Special Topics, March 2004
    An INTERVIEW with Dr. Wolfgang Ketterle

    What do you see for the next five years of research on Bose-Einstein condensation?


    One goal is the use of condensates for advancing atom optics, to develop new or improved matter wave sensors. In condensed-matter physics, we have two big goals. We would like to use ultra-cold atoms to realize new forms of matter. You could call it designer matter. You take atoms, you turn on a magnetic field, you adjust the interactions between the atoms, shape the external potential, maybe add a lattice by interfering laser beams, maybe add magnetic fields, maybe add a spin mixture. In this way, you’ve created a form of matter that shows, in a very clean way, properties like anti-ferromagnetism or different forms of magnetic ordering, superfluid behavior. The other big goal would be to realize new forms of superfluidity. That would hopefully help to close the gap in our understanding of high-temperature superconductivity. That’s my dream.


    It's as if if someone wanted to map the very nature of particle creation, what roads would lead to a most appropriate solution to Mendeleev's table of matter idenfication scale, that we could have said this situation has an outcome. We might say that this particle is the very beginning, expressed in nature, inhernet in the outcome of the standard model.

    The Tao of Quantum Interrogation

    A detective limited to the realm of classical physics is in trouble. He can go into a completely darkened room, and pry off the lid of the crate. Then what? If there really is no light at all -- if no photons at all hit the trigger element -- then he gets no information. If, on the other hand, a single photon hits the element, well then by definition there is a loud explosion, and the detective knows that this was a good bomb. There seems to be no way to find the good bombs without always exploding them.



    You know I have this picture in mind. If I had thought it holographical by nature, what constituted the different "views of the picture"? If I were to look at it from coordinated references, what would say that from this "x" angle, that the contituents of the picture, y and z, can be assumed ?

    A Hint of Things To Come continue from Quantum Interrogation above
    Finally, another avenue we are currently exploring is to extend the above techniques to allow two-dimensional imaging of an object. As a simple example, one could then make an in situ movie of a Bose-Einstein condensate without blowing it up, since very few of the photons actually end up being absorbed by the ultra-cold condensate atoms. (Practically speaking, however, the latest far-off-resonance methods of Ketterle et al. are likely to be more....practical.)

    In conclusion, it is not altogether clear what wonderful applications the principles of interaction-free measurements will have, but it is certain that some very interesting physics is yet to be uncovered.


    It's difficult for my layman mind to grasp this. but I am trying. The question here are the result of the experiment on Quantum Interrogation. It's as if the question itself, saids that the other aspects of the result are immediately apparnet when observed as the result in the x direction.

    The Lowest Octave State

    Sometimes simple concepts, like something representing the lowest vibration mode of the string, the lowest octave helps in a sense helps to orientate what the particles mean, such as protons,neutrons and electrons. Where they exist now as they cosmic collsions meet and dissapte it's influence in our atmospheres, our planet.

    Yet Moshe speaking about sparticles has interesting relations in context of symmetry breaking, yet, without thinking about what experiments are now being listed, what value this lowest vibration mode? What value that leads us to think about this lower scale as evidence now held within our views.

    Clifford:
    We’ve got to remember what we assumed in order to get to the cirtical dimensions, and then revisit those assumptions every time we learn something new about the whole story


    Would be a consistent pattern, when new options and experimental consideration are introduced. In the case I listed above in ICECUBE.

    The relative 'up' and 'down' rates provide evidence for distortions in neutrino properties that are predicted by new theories."


    I think this would be consistent on the level of what you are saying Clifford? Lay people like myself would understand this I think. While very aware of the higher energy considerations in context of reductionism, had taken us too dual blackhole considerations within the collisions taking place not just in the colliders.

    It presented opportunites in how we see what strings might have emplied in Cerenkov radiation? What is it that we should see in this relation, that strings would have said here is another opportunity?

    Cerenkov Radiation and the Blue Glow

    At full power (200 kilowatts), the UMR Reactor core produces approximately 6.4 trillion fissions per second. Each fission event liberates a tremendous amount of energy, a portion of which is carried away by fission products which then decay and produce high-energy beta particles. Often, these beta particles are emitted with such high kinetic energies that their velocities exceed the speed of light (3.0x108 meters per second) in water. When this occurs, photons, seen to the eye as blue light, are emitted and the reactor core "glows" blue.

    While no particle can exceed the speed of light in a vacuum, it is possible for particles to travel faster than light in certain mediums, such as water. The speed of light in a particular medium, v, is related to the speed of light in a vacuum, c, by the index of refraction, n, by v = c/n. Water has an index of refraction of 1.3, thus the speed of light in water is 2.3x108 meters per second. Therefore, beta particles with kinetic energies of 0.26 MeV travel at speeds in excess of 230 million m/s!


    It is important to remember somethings here. I am trying to hone in on the exact reasons for this idealization, to see in the ways that we do. Why the sky is blue in relation to the sun that shines and the Earth as it is ?:) How often has the child asked, while we had been witness to the very thing in our everyday waking lives.

    Thus we are quickly transported into the strange world of refractve indexes and such, as examples of what angle and departures these particle might take in their collisions courses. Yet we know as we look up that beyond the blue, it gets dark again Redshifting on the horizons as our sun sets.

    Cosmological particles exsit that are free of our atmosphere. What say these things in that environ, while it is dark? What shall we say of these things when the sun influences dances on our outer atmosphere?

    Wikipedia and the Uses of Cerenkov Radiation(8 Feb 2006)

    When a high-energy cosmic ray interacts with the Earth's atmosphere, it may produce an electron-positron pair with enormous velocities. The Cherenkov radiation from these charged particles is used to determine the source and intensity of the cosmic ray, which is used for example in the Imaging Atmospheric Cherenkov Technique (IACT), by experiments such as H.E.S.S. and MAGIC. Similar methods are used in very large neutrino detectors, such as the Super-Kamiokande.


    So I am again drawn back to the state of the earth's gravitational field, with which this planet being weak, lets us see particle states that it does? How shall I keep in mind, that such circumstance free of refractive indexes( a vacuum)speed of light wil mett the chance to have faster then light capabilties, in a blue glow? Have I then nailed the reasons why such concepetualization take to the two extrmes of what vison had garnered for us, and the circles meaningwhile it signfied this interchangeability?

    Ah, my more layman head. :)Like a Koan supplied to tax the mind, a simple statement is drawn out, over and over again, while in time, the mind becomes flooded with so many possibilities with a flash of light. What is this Koan, that I speak of?

    Brian Greene:
    How can a six-foot tall human being 'fit' inside such an unbelievably microscopic universe? How can a speck of a universe be physically identical to the great expanse we view in the heavens above


    Don't worry Clifford, while Brian Greene might have been the spokesperson for all scientist actors, it is still with some benefit that we undertand how the abstract mind releases itself, but for a short time. While the influence of nature has its way with us. Whilst we had been so intensely looking, the break from the work, allowed the culmination to seep through in a simple jesture of understanding. That seems to be the way of it.

    Spacetime 101

    Here's some basic background covering how mathematical models of space and time have evolved since ancient times, from the Pythagorean Rule to Newtonian mechanics, Special Relativity and General Relativity.





    For the roads leading to one's view of the strange world of non-euclidean views had to offer, I of course needed some model from which to work. As I looked at the model above and the transfer of higher dimensional thinking, the very idea and contrast to the lower image represented, how would you associate gravity in the diagram but watch the circle valution along side of gravity that emegres from the 2d discription as a energy valution, and relationship to gravity, evolving from mass, energy interconnectivity. I have to apologize as I was developing and am developing.



    I do not know if this is right to assign my view above, while one did not know the evaluation of 1R as I watch DRL assessment of what can no longer be considered as valid, I have to wonder why such observations are not thought about more intricately as the valuation of that circle is considered. The comparison was drawn between the two pictures of the spacetime fabric above here, and below.

    Let's now start analysing a 2D case, that of the classic Flatland example, in which a person lives in a 2D universe and is only aware of two dimensions (shown as the blue grid), or plane, say in the x and y direction. Such a person can never conceive the meaning of height in the z direction, he cannot look up or down, and can see other 2D persons as shapes on the flat surface he lives in.


    So if you follow the dimensional analysis, there is a systemic procedure that one has to follow, that does not have to be held in context of KK interpretation to this point, but it does help if you think about the very basis of this graduation that certain statements make themself known.

    Degrees of freedom(Wiki 24 Jan 2006)

    Point
    Zero-dimensional space

    Why 10 dimensions?
    Calabi-Yau spaces
    Infinitely many dimensions
    Banach space (only some have infinitely many dimensions)
    Special relativity
    General relativity


    Would you dimiss a comment by Greene because of the speculation you have felt about him that you might not recognize, what is being said as you watch that circle develope alongside of the sphere, as it moves through the 2d discription? Here's what mean, as I had focused on Brian Greene's words.

    Angular momentum can twist light cones and even make time travel possible in theory if not in practice.


    The familiar extended dimensions, therefore, may very well also be in the shape of circles and hence subject to the R and 1/R physical identification of string theory. To put some rough numbers in, if the familiar dimensions are circular then their radii must be about as large as 15 billion light-years, which is about ten trillion trillion trillion trillion trillion (R= 1061) times the Planck length, and growing as the universe explands. If string theory is right, this is physically identical to the familiar dimensions being circular with incredibly tiny radii of about 1/R=1/1061=10-61 times the Planck length! There are our well-known familiar dimensions in an alternate description provided by string theory. [Greene's emphasis]. In fact, in the reciprocal language, these tiny circles are getting ever smaller as time goes by, since as R grows, 1/R shrinks. Now we seem to have really gone off the deep end. How can this possibly be true? How can a six-foot tall human being 'fit' inside such an unbelievably microscopic universe? How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
    ( Brian Greene, The Elegant Universe, pages 248-249)

    Fifth dimension(wiki 24 Jan 2006)
    Abstract, five dimensional space occurs frequently in mathematics, and is a perfectly legitimate construct. Whether or not the real universe in which we live is somehow five-dimensional is a topic that is debated and explored in several branches of physics, including astrophysics and particle physics.

    Special holonomy manifolds in string theory

    So what instigated my topic today and Hypercharge make sits way for me to reconsider, so while doing this the idea of geoemtries and th eway in which we see this uiverse held to the nature of it's origination are moving me to consider how we see in ths geometrical sense.

    The resurgence of ideas about the geometries taking place are intriguing models to me of those brought back for viewing in the Sylvester surfaces and B field relations held in context of the models found in the >Wunderkammern.

    This paragraph above should orientate perception for us a bit around methods used to see in ways that we had not seen before. This is always very fascinating to me. What you see below for mind bending, helps one to orientate these same views on a surface.



    Hw would you translate point on a two dimensional surface to such features on the items of interest on these models proposed?



    Part of my efforts at comprehension require imaging that will help push perspective. In this way, better insight to such claims and model methods used, to create insight into how we might see those extra 10 dimensions, fold into the four we know and love.



    G -> H -> ... -> SU(3) x SU(2) x U(1) -> SU(3) x U(1).

    Here, each arrow represents a symmetry breaking phase transition where matter changes form and the groups - G, H, SU(3), etc. - represent the different types of matter, specifically the symmetries that the matter exhibits and they are associated with the different fundamental forces of nature



    If one held such views from the expansitory revelation, that our universe implies at these subtle levels a quantum nature, then how well has our eyes focused not only on the larger issues cosmology plays, but also, on how little things become part and parcel of this wider view? That the quantum natures are very spread, out as ths expansion takes place, they collpase to comsic string models or a sinstantaneous lightning strikes across thei universe from bubbles states that arose from what?

    So knowing that such features of "spherical relation" extended beyond the normal coordinates, and seeing this whole issue contained within a larger sphere of influence(our universe), gives meaning to the dynamical nature of what was once of value, as it arose from a supersymmetrical valuation from the origination of this universe? If Any symmetry breaking unfolds, how shall we see in context of spheres and rotations within this larger sphere, when we see how the dynamcial propertties of bubbles become one of the universes as it is today? Genus figures that arise in a geometrodynamcial sense? What are these dynacis within context of the sphere?



    So as I demonstrate the ways in which our vision is being prep for thinking, in relation to the models held in contrast to the nature of our universe, how are we seeing, if we are moving them to compact states of existance, all the while we are speaking to the very valuation of the origination of this same universe?



    Holonomy (30 Dec 2005 Wiki)

    Riemannian manifolds with special holonomy play an important role in string theory compactifications. This is because special holonomy manifolds admit covariantly constant (parallel) spinors and thus preserve some fraction of the original supersymmetry. Most important are compactifications on Calabi-Yau manifolds with SU(2) or SU(3) holonomy. Also important are compactifications on G2 manifolds.

    The Single Photon Experiment at Rowan University is a Success!

    Einstein/Bohr Debate

    "Not often in life has a man given me so much happiness by his mere presence as you have done," Einstein wrote to Bohr. "I have learned much from you, mainly from your sensitive approach to scientific problems."



    John G. Cramer
    This column is about experimental tests of the various interpretations of quantum mechanics. The question at issue is whether we can perform experiments that can show whether there is an "observer-created reality" as suggested by the Copenhagen Interpretation, or a peacock’s tail of rapidly branching alternate universes, as suggested by the Many-Worlds Interpretation, or forward-backward in time handshakes, as suggested by the Transactional Interpretation? Until recently, I would have said that this was an impossible task, but a new experiment has changed my view, and I now believe that the Copenhagen and Many-Worlds Interpretations (at least as they are usually presented) have been falsified by experiment.



    The Single Photon Experiment at Rowan University is a Success!

    Entanglement applies to two or more particles even if one of them is used as input to the two slit experiment, it is not applicable to single particle experiments.

    Afshars experiment is conducted in such a manner that it is the setup of the experiment coupled with the conservation of momentum that allows us to know exactly which slit the photon has gone through.

    Whilst knowing which way the photon has gone we also manage to show the absense of interference with both slits open via intererence minima
    .



    Measurement without “measurement”: Experimental violation of Complementarity and its aftermath
    Bohr’s Principle of Complementarity of wave and particle aspects of quantum systems has been a cornerstone of quantum mechanics since its inception. Einstein, Schrödinger and deBroglie vehemently disagreed with Bohr for decades, but were unable to point out the error in Bohr’s arguments. I will report three recent experiments in which Complementarity fails, and argue that the results call for an upgrade of the Quantum Measurement theory. Finally, I will introduce the novel concept of Contextual Null Measurement (CNM) and discuss some of its surprising applications. Web-page: users.rowan.edu/~afshar/ Preprint (published in Proc. SPIE 5866, 229-244, 2005): http://www.irims.org/quant-ph/030503/


    Violation of the principle of complementarity, and its implications
    Shahriar S. Afshar


    Bohr's principle of complementarity predicts that in a welcher weg ("which-way") experiment, obtaining fully visible interference pattern should lead to the destruction of the path knowledge. Here I report a failure for this prediction in an optical interferometry experiment. Coherent laser light is passed through a dual pinhole and allowed to go through a converging lens, which forms well-resolved images of the respective pinholes, providing complete path knowledge. A series of thin wires are then placed at previously measured positions corresponding to the dark fringes of the interference pattern upstream of the lens. No reduction in the resolution and total radiant flux of either image is found in direct disagreement with the predictions of the principle of complementarity. In this paper, a critique of the current measurement theory is offered, and a novel nonperturbative technique for ensemble properties is introduced. Also, another version of this experiment without an imaging lens is suggested, and some of the implications of the violation of complementarity for another suggested experiment to investigate the nature of the photon and its "empty wave" is briefly discussed.

    Decoherence

    How to understand this quantum-to-classical transition linking two incompatible descriptions of reality is still a matter of debate among the various interpretations of quantum theory. In any case, one can probe the borderline between the classical and the quantum realm by performing interference experiments with particles of increasing complexity.


    Of course I am cocnerned about the determinations of the paticle natures seen in a particular light. These constituent s are part an dparcel of a much larger view from increase entrophy( I always get these things a**backwards), and cooling temperatures?

    Decoherence is relevant (or is claimed to be relevant) to a variety of questions ranging from the measurement problem to the arrow of time, and in particular to the question of whether and how the ‘classical world’ may emerge from quantum mechanics. This entry mainly deals with the role of decoherence in relation to the main problems and approaches in the foundations of quantum mechanics.


    Of course I am paying attention and listening. :)Of course I want to find my way back to the classical world from where probabilistic valuations reigned. I was acting as a "gathering point" in my quest for a "philosophical design" (not to be confused with ID?). :) Okay, I understand this is not acceptable.


    The difference between quantum and classical behaviour is exemplified by the famous “double-slit experiment”, in which photons are fired at a barrier containing two slits, and then allowed to fall on a screen opposite the barrier. Classical particles would pass through (at most) one slit at a time, but photons can pass through both simultaneously. The two waves associated with the photon passing through the two different slits fall in and out of phase with each other at different points on the screen — the phase of these waves being related to the total distance the photon travels from source to screen — so they interfere either constructively or destructively, producing a pattern of light and dark bands.




    What motivated such cosmlogical design, as a crunching inevitable to have found the limitations of the energy having found itself turning back? So we do not see this right now and we speculate. this did ont take away from the isolated examples of unfoldment as a cyclcical process between energy and matter did it??

    Oh for heaven's sake, where will my ramblings take me next? :)

    Lubos Motl:
    I would not promote overly technical lecture notes, especially not about things covered in many books. But the interpretation of quantum mechanics in general and decoherence in particular - a subject that belongs both to physics as well as advanced philosophy - is usually not given a sufficient amount of space in the textbooks


    Those are strong words [shut up and calculate] for a layman to consider, when he is groping to trying to find his way.

    Lecture 23 was pointed out by Lubos Motl in his article for consideration. More was considered from the list contained here.

    If such energies were to be amongst the recognition of the quantum world, had we really been that separated from cosmological recognition of what constitued that beginning? Am I suppose to dismiss Weinberg in his first three minutes, for what might have been recognized in the first three seconds?? Remeber I am in the fifth dimension, where temeprature and entropic findings would have found a furthe rvalue to the discussion of what went this way and what that way. The entangling process is very profound.

    So in looking back, we do not know where such a thing could begin? I think I understand that from what , although, if such proceses were recognized in the cyclcial nature of the cosmos why would we not entertain the rejuvenation of geometrical propensities to models inherent already in the universe? See the universe as a much "larger process" much different then the scope through which we might have treated each galaxy in it's rotations? Everett? Hmmm....

    To map the "invisible" Universe of dark matter and gas expelled during the birth of galaxies: a large-aperture telescope for imaging and spectroscopy of optical and ultraviolet light.

    To measure the motions of the hottest and coldest gas around black holes: a radio interferometer in space.

    To see the birth of the first black holes and their effect on the formation of galaxies, and to probe the behavior of matter in extreme environments: a very large aperture arc-second X-ray imaging telescope.

    To determine the nature and origin of the most energetic particles in the Universe today: a mission to track them through their collisions with the Earth.


    I have been troubled indeed by the "orbital mapping" I speculated to the cosmological design, seen as "events" in that cosmo. By such happen stance, such relations seem to spark some wonder about the arrangement, to the fundamental library of that same orbital design. I made this mistake before, and I need to correct it now.

    Slow down! "Antimatter?" "Pure energy?" What is this, Star Trek?

    But you can see evidence for antimatter in this early bubble chamber photo. The magnetic field in this chamber makes negative particles curl left and positive particles curl right. Many electron-positron pairs appear as if from nowhere, but are in fact from photons, which don't leave a trail. Positrons (anti-electrons) behave just like the electrons but curl in the opposite way because they have the opposite charge. (One such electron-positron pair is highlighted.)


    The collider ring as a boson, whose overall contention could have been seen in the total energy involved, and the dispensing to those extra dimensional perspectives within the "natural world" of our settings? Have I misunderstood the values of the Pierre Auger experiment to see better, then we had seen before, not to have seen a topological question about how one would interpret the sphere with one hole, as a donut? What values circles then?


    Decoherence represents an extremely fast process for macroscopic objects, since these are interacting with many microscopic objects in their natural environment. The process explains why we tend not to observe quantum behaviour in everyday macroscopic objects since these exist in a bath of air molecules and photons. It also explains why we do see classical fields from the properties of the interaction between matter and radiation.


    Angels/demons seem to make there way into view here? Yet in the world of Dirac might he seen the consequence of possible pathways in the construction of the matrix involved and intoduced the i of questionable directives as results in the arrangement of that same matrix?? Feynman took over for sure in his toy models.

    Then of course I come across this statement previous and I am back to scratching my head. Oh boy!

    You might imagine antimatter as a possible temporary storage medium for energy, much like you store electricity in rechargeable batteries. The process of charging the battery is reversible with relatively small loss. Still, it takes more energy to charge the battery than what you get back out of it. For antimatter the loss factors are so enormous that it will never be practical.

    If we could assemble all the antimatter we've ever made at CERN and annihilate it with matter, we would have enough energy to light a single electric light bulb for a few minutes.


    Hmmmm......more confusion again.:)



    What value from such gravitonic perceptions from the modifications if events such as these above are not held to the dynamical nature of the spacetime fabric itself?

    The Future of the Book

    I have definite ideas about the future in this medium Clifford.

    First let me say, that Indymedia was the first introduction to "real time" reporting aside from TV network medias distributors. If you could bring other perspectives to the realites of our world, then indeed media in terms of pictures, live video shots, could help you present more ideas to the public.

    How much of a effect does this have?

    One might talk about blogging and the effect it has about giving power to the individual in the street to prersnt views from the front lines. Has been well along in it's developemental stages. I am just presentng a safe scenario and the pushing of the envelope to considerations of laws about copyright/copyleft? To bring this dynamcial world of the internet into a responsible forum of the development of minds.



    If one knew the fog that is created in life, askes for the Clear MInd, then where shall we begin? A Tibetan might ask for a priest at his bedside(Tibetan Book of the Dead), so that he can walk the indivdidual through the trepidations of a "material world" as one is dying. To help one realize to this Clear light?

    It had to begin then that if minds are going to involve themselves in a sphere of personalities, then they should be well prepared for how this developmental process is evovling our consciousness. How historical figures are part and parcel of the history of the world on another level that we do not see? Rings around this planet? Rings around us? What is the color of your mind?

    My mind goes back first though in a historical sense to Gamow. I know most do not like to live in the past, but this sets up certain ideas about the future. The freedoms of expression. The developemental idealization of a free society, and not one held too.



    Most of us know who Richard Stallman is right?



    The GNU?


    I was thinking of the Cathedral and the Bizzare, Netscape and Microsoft, and how this developement is moved to ideas about the creative commons and the desire of what that "future book" should be?

    Making Prisons for our Children's Minds



    The dangers of being held into Doom conspirative games while introducing story forms for a pro-active idealization about "using toys" to encourage destructive attitudes? Locking our childrens "minds" within rooms of destruction? Predators who prey on our children.

    Future of Blogging

    In one sense the idea about the pictures and how they are implemented in these blogging articles, and the way html works from blogging to weblog. The future of the mind of the internet

    We seen Jacques's disgust with the way you see things in Word Press and the way they end up appearing? Uiversal html directtives applicable to all blogging software

    The limitation put on those who would like to use imaging, but are cut out because of the adminstrative duties held for Cosmic Variance Little Rascals. Here in this blogging sphere, will others be allowed to post their pictures?

    What is this future that our minds are evolving too, as we sit at the desk and find others of like mind across from us. Have entered the world of personalilites and have left the planet for another type of world?

    Some Distant Bounding Surface



    I mean when I referred to fifth dimensional views you know that the computer screen includes not only it's functionability in relation to science, but adds that bit of extended flavour to model construction we call imaging right?


    a) Compactifying a 3-D universe with two space dimensions and one time dimension. This is a simplification of the 5-D space­time considered by Theodor Kaluza and Oskar Klein. (b) The Lorentz symmetry of the large dimension is broken by the compactification and all that remains is 2-D space plus the U(1) symmetry represented by the arrow. (c) On large scales we see only a 2-D universe (one space plus one time dimension) with the "internal" U(1) symmetry of electromagnetism.


    Remember Brian Greene's is from 2001. What might have change since then with Brian Greene and his views about about that distant bounding surface. Of course to many of us it is a brane world recognition.



    If we did not recognize what advancements might have been accomlished with mathematics and the fifth dimensional views on our computer screens? Could we ever really talk about such idealizations, without understanding that there are ways to look at this, and reductional valuations taken from fifth dimensional views down to 2? Our computer screen. Of course Brian Greene has included the thickness of the bounded surface, so, time had to be inclusive here would it not?:)

    The Edge

    Physics and everything we know in the world around us may really be tied to processes whose fundamental existence is not here around us, but rather exists in some distant bounding surface like some thin hologram, which by virtue of illuminating it in the right way can reproduce what looks like a 3-dimensional world. Perhaps our three dimensional world is really just a holographic illumination of laws that exist on some thin bounding slice, like that thin little piece of plastic, that thin hologram. It's an amazing idea, and I think is likely to be where physics goes in the next few years or in the next decade, at least when one's talking about quantum gravity or quantum string theory.

    So how can such a thing as Brian calls a Bounded surface and relate it's thinness to a vast capability? Also in the cosmic perspective, to have brane collisions illustrated by Steinhardt, become much more then our views held to the surface mathematically inclined. To be revealled, in stringy dynamics, at the basis of our viewing?

    Such creation slotted into the time frames of this beginning, is stil questioning the valuation of what existed before stringy ideas manifest, so what pray tell, could have ever been "the sun" in behind, that illuminates "shadows" on the wall?

    The Randall-Sundrum braneworld model is characterized by ordinary matter being confined to a hypersurface embedded in a higher-dimensional manifold through which gravitational signals may propagate


    Physics strings us along by Margaret Wertheim of LAtimes.com

    In the latest, hottest Big Science tome — the delightfully titled "Warped Passages" — Harvard physicist Lisa Randall describes the idea that the universe we see around us is but one tiny part of a vast reality that may include an infinite number of other universes. Randall is an expert on both cosmology and that arcane branch of particle physics known as string theory. By marrying the two fields, she and her colleagues have formulated a picture in which our universe may be seen as a soap-film-like membrane (a "braneworld") sitting inside a much larger space: the bulk. According to general relativity, the universe we live in has four dimensions: three of space and one of time. Randall's work extends this framework and posits the existence of a fifth dimension. The fifth dimension is the bulk, and within its immeasurably expanded space, there is no reason to assume that ours is the only cosmos.


    So there are amazing leaps here then to new world recognitions of ideologies that formed from where?

    John Ma Pierre:
    What is remarkable is that much of the recent progress in understanding non-perturbative aspects of string theory and supersymmetric gauge theories has been made in parallel, using each to gain knowledge and insights about the other. There are various reasons for this intimate connection between supersymmetric gauge theories and string theory. One is that supersymmetric gauge theories arise as low energy effective descriptions of compactified string theories in limits where gravity decouples. Another reason is that superstring theories can be formulated in backgrounds that contain D-branes, and supersymmetric gauge theories serve as effective world volume theories for these D-branes. In addition to these direct examples, it is sometimes the case that intuition about non-perturbative physics that is gained in one area can be directly applied to the other. An example of this is the guiding principle that singularities in the quantum moduli space of a low energy effective theory signal the appearance of new massless states. This was seen to be a generic phenomena in supersymmetric gauge theories and was subsequently applied to the resolution of conifold singularities by massless black holes in string theory.


    Wow! More then five!:) Okay reference was made by Sean on a one liner about magic and his meeting in a bar. Where a sister as the science teacher explains this statement. Well it has been gathered up for consumption in other areas, so of course we have to explain this as now this conversation is leading other talks to consider more issues about what began as a mystery has no place in the developement of science.

    I am a little dismayed by this, because anomlistic features without explanation would seem as such, while it is true, that it can be expalined afterwards, once we understood how something from the 21st century dropped into our laps for consideration:) We know what this means right? It had to be coisstent and logicall so repeatability can hav eother hands , for verification. How did you expalin it and lead them hwere one had not gone before?

    That sounded like Startrek for a minute there:)

    Mathematical Models

    "Backwards" might mean, from a "5d understanding" to a three dimensional fabrication. You had to understand how the 5d world is explained here, before judgement is cast.

    While I would like nothing more then to cater to the struggles of good professors, to the aims they had set for themselves, it has come to me, that mathematic modelling is culminative. Where does this point too?

    If indeed a good understanding has been established, regardless of string theory or any association for that matter, this stand alone item on Langlands or what ever one might associated it too, would of itself, painted it's own picture and further associations, from a basis and exposition of that mathemtical derivative.

    It does not have to be associated it either to historical figures (like Plato), other then the ones we trace to the orignation and factors that brought other areas of mathematics together. This should be readily available, by doing searches which I did. Although I sahl say there is much that needs to be resolved, in our determinations of truth. I am working on understanding this here.

    But then to take it further, I wanted to illustrate this point just a little more on imaging.

    Thomas Banchoff has set this straight in terms of modelling in computerization and what it can do for us in 5D expressions? While in the Wunderkammern of this site such model although concretize in form have relative associations in computerization value much like the model of the Klein bottle exemplified of itself in acme products.


    x = cos(u)*(cos(u/2)*(sqrt_2+cos(v))+(sin(u/2)*sin(v)*cos(v)))

    y = sin(u)*(cos(u/2)*(sqrt_2+cos(v))+(sin(u/2)*sin(v)*cos(v)))

    z = -1*sin(u/2)*(sqrt_2+cos(v))+cos(u/2)*sin(v)*cos(v)

    or in polynomial form:

    Yep, no doubt about it: Your Acme's Klein Bottle is a real Riemannian manifold, just waiting for you to define a Euclidean metric at every point.



    Felix Klein
    When Klein became a Professor in Leipzig in 1880, he immediately started to acquire mathematical models and establish a model collection. Klein was a geometer and used these plaster models in his university lectures. Model collections became very popular in mathematics departments world-wide. When he then moved to Göttingen, Klein, together with his colleague Hermann Amandus Schwarz, expanded his new department's collection of mathematical models and instruments so much that at peak times up to 500 models were on permanent display. When you think that a model could cost about £150, this was a major investment in education.




    This idea is and has been lost to the model archives of the Wunderkammern respectively and such a resurgence is making it's way back. Such O ->an outward expression is no less the road taken in artistic expression entitled, "When is a Pipe a pipe," exemplified in the manifestation of mathematical modelling.

    Our computer screen although reduced to two dimensional factors, is a fifth dimensional expression, in terms of our visulization capability. The work then is translation of computerization, to imaging.

    The "Torso" once mathematically derived, and help enlisted in the Cave, brought mathematical equation through a complete rotation in the Calabi Yau. Until then, the efforts relied on by men/woman whose visualization capabiltes, were equivalent to 5d imaging?

    So if I ask, if there is a image of a culminative mathe, without out this the understanding is not complete.

    The Succession of thinking

    How far indeed the the imagination can be taken to see such processes enveloped in how we percieve these changes all around us. Why is gravity so weak, here and now. I have jumped ahead but will lead into it from the other end of this article.

    Never before had I encountered the reasoning of imaging behind the work of "conceptual frameworks" now in evidence. In how a mathmatician, or a scientist, like Einstein or Dirac, had some basis at which the design, of all that we endure, would have its's counterpart in this reality as substantial recognition of what must be done.

    I don't think anyone now in the scientific arena needs to be reminded about what it takes to bring theory into the framework of cultural and societal developement, to see how it all actually is working. On and on now, I see this reverberating from Lisa Randall to all scientists that we encounter from one blog to the next, a recognition and developement of this visualization ability.

    That Famous Equation and You , By BRIAN GREENE Op-Ed Contributor in New York Times, Published: September 30, 2005


    Brian Greene:
    After E = mc², scientists realized that this reasoning, however sensible it once seemed, was deeply flawed. Mass and energy are not distinct. They are the same basic stuff packaged in forms that make them appear different. Just as solid ice can melt into liquid water, Einstein showed, mass is a frozen form of energy that can be converted into the more familiar energy of motion. The amount of energy (E) produced by the conversion is given by his formula: multiply the amount of mass converted (m) by the speed of light squared (c²). Since the speed of light is a few hundred million meters per second (fast enough to travel around the earth seven times in a single second), c² , in these familiar units, is a huge number, about 100,000,000,000,000,000.


    There are two links here.One by Peter Woit with reference to article and one toSean Carroll who further illucidates the article by Brian Greene.

    So here I am at the other end of this referenced article, that other thoughts make their way into my mind. Previous discussison ongoing and halted. To todays references continued from all that we had encountered in what General Relativity surmizes.

    That this issue about gravity is very real. So that's our journey then, is to understand how we would percieve the strength and weakness through out the spacetime and unification of a 3 dimension space and one of time, to some tangible reality within this coordinated frame Euclidean defined.

    The Succession of Thinking

    Mark helps us see in a way we might not of considered before.

    Dark Matter and Extra-dimensional Modifications of Gravity

    But the issue is much more complicated then first realized if we take this succension of thinking beyond the carefuly plotted course Einstein gave us all to consider.

    Plato on Sep 27th, 2005 at 10:23 pm We were given some indications on this site about the state of affairs with Adelberger. Do you think this time span of proposed validation processes, were constructively and experimentally handled appropriately through it’s inception? As scientists would like to have seen all such processes handled in this respect?

    So indeed I began to see this space as very much alive with energy that had be extended from it's original design to events that pass through all of creation, then how indeed could two views be established in our thiniking, to have Greene explain to us, that the world holds a much more percpetable view about what is not so understood in reality.

    An Energy of Empty Space?

    Einstein was the first person to realize that empty space is not nothingness. Space has amazing properties, many of which are just beginning to be understood. The first property of space that Einstein discovered is that more space can actually come into existence. Einstein's gravity theory makes a second prediction: "empty space" can have its own energy. This energy would not be diluted as space expands, because it is a property of space itself; as more space came into existence, more of this energy-of-space would come into existence as well. As a result, this form of energy would cause the universe to expand faster and faster as time passes. Unfortunately, no one understands why space should contain the observed amount of energy and not, say, much more or much less.


    All the while the ideas that would leave gravity without explanation in a flat euclidean space, gravity would have been left to that solid response without further expalnatin in a weak field manifestation. But it was always much more then this I think.

    While being caution once on what the quantum harmonic oscillator is not, Smolin did not remove my thinking of what was all pervasive from what this "empty space" might have implied, that heretofor "it's strength" was a measure then of a bulk, and what better way in which to see this measure?

    Taken in context of this succession, this place where such conceptual framework had been taken too, it was very difficult not to encounter new ways in which to understand how gravity could changed our perceptions.

    Thalean views were much more then just issues about water and all her dynamical explanations. It presented a new world in which to percieve dynamical issues about which, straight line thinking could no longer endure. A new image of earth in all it's wander, no less then Greene's analysis to how this famous equation becomes evident in our everyday world. It presented a case for new geometries to emerge. Viable and strengthened resolve to work in abstract spaces that before were never the vsion of men and women who left earth. Yet it all had it's place to endure in this succession that we now have adbvanced our culture in ways that one would not have thought possible from just scientific leanings.

    So now I return myself to Einstein's allegorical talk on what concept had taken, when a scientist had wondered on the valuation of time.

    Kilometric Radiation?



    So we use physics in ways to change the way we see? Here are some examles from the Cassini Project and Wikipedia.

  • Cassini Plasma Spectrometer (CAPS)
    The Cassini Plasma Spectrometer (CAPS) is a direct sensing instrument that measures the energy and electrical charge of particles such as electrons and protons that the instrument encounters. CAPS will measure the molecules originating from Saturn's ionosphere and also determine the configuration of Saturn's magnetic field. CAPS will also investigate plasma in these areas as well as the solar wind within Saturn's magnetosphere.[1]


  • Cosmic Dust Analyzer (CDA)

    The Cosmic Dust Analyzer (CDA) is a direct sensing instrument that measures the size, speed, and direction of tiny dust grains near Saturn. Some of these particles are orbiting Saturn, while others may come from other solar systems. The Cosmic Dust Analyzer onboard the Cassini orbiter is ultimately designed to help discover more about these mysterious particles, and significantly add to the knowledge of the materials in other celestial bodies and potentially more about the origins of the universe.[2]


  • Composite Infrared Spectrometer (CIRS)

    The Composite Infrared Spectrometer (CIRS) is a remote sensing instrument that measures the infrared light coming from an object (such as an atmosphere or moon surface) to learn more about its temperature and what it's made of. Throughout the Cassini-Huygens mission, CIRS will measure infrared emissions from atmospheres, rings and surfaces in the vast Saturn system to determine their composition, temperatures and thermal properties. It will map the atmosphere of Saturn in three dimensions to determine temperature and pressure profiles with altitude, gas composition, and the distribution of aerosols and clouds. This instrument will also measure thermal characteristics and the composition of satellite surfaces and rings.[3]


  • Ion and Neutral Mass Spectrometer (INMS)

    The Ion and Neutral Mass Spectrometer (INMS) is a direct sensing instrument that analyzes charged particles (like protons and heavier ions) and neutral particles (like atoms) near Titan and Saturn to learn more about their atmospheres. INMS is intended also to measure the positive ion and neutral environments of Saturn's icy satellites and rings.[4]


  • Imaging Science Subsystem (ISS)

    The Imaging Science Subsystem (ISS) is a remote sensing instrument that captures images in visible light, and some in infrared and ultraviolet light. The ISS has a camera that can take a broad, wide-angle picture and a camera that can record small areas in fine detail. Scientists anticipate that Cassini scientists will be able to use ISS to return hundreds of thousands of images of Saturn and its rings and moons. ISS includes two cameras; a Wide Angle Camera (WAC) and a Narrow Angle Camera (NAC). Each uses a sensitive charge-coupled device (CCD) as its detector. Each CCD consists of a 1,024 square array of pixels, 12 μm on a side. The camera's system allows for many data collection modes, including on-chip data compression. Both cameras are fitted with spectral filters that rotate on a wheel—to view different bands within the electromagnetic spectrum ranging from 0.2 to 1.1 μm.[5]


  • Dual Technique Magnetometer (MAG)

    The Dual Technique Magnetometer (MAG) is a direct sensing instrument that measures the strength and direction of the magnetic field around Saturn. The magnetic fields are generated partly by the intensely hot molten core at Saturn's center. Measuring the magnetic field is one of the ways to probe the core, even though it is far too hot and deep to actually visit. MAG's goals are to develop a three-dimensional model of Saturn's magnetosphere, as well as determine the magnetic state of Titan and its atmosphere, and the icy satellites and their role in the magnetosphere of Saturn.[6]


  • Magnetospheric Imaging Instrument (MIMI)

    The Magnetospheric Imaging Instrument (MIMI) is both a direct and remote sensing instrument that produces images and other data about the particles trapped in Saturn's huge magnetic field, or magnetosphere. This information will be used to study the overall configuration and dynamics of the magnetosphere and its interactions with the solar wind, Saturn's atmosphere, Titan, rings, and icy satellites.[7]


  • Radio Detection and Ranging Instrument (RADAR)

    The Radio Detection and Ranging Instrument (RADAR) is a remote active and remote passive sensing instrument that will produce maps of Titan's surface and measures the height of surface objects (like mountains and canyons) by bouncing radio signals off of Titan's surface and timing their return. Radio waves can penetrate the thick veil of haze surrounding Titan. In addition to bouncing radio waves, the RADAR instrument will listen for radio waves that Saturn or its moons may be producing.[8]


  • Radio and Plasma Wave Science instrument (RPWS)

    The Radio and Plasma Wave Science instrument (RPWS) is a direct and remote sensing instrument that receives and measures the radio signals coming from Saturn, including the radio waves given off by the interaction of the solar wind with Saturn and Titan. The major functions of the RPWS are to measure the electric and magnetic wave fields in the interplanetary medium and planetary magnetospheres. The instrument will also determine the electron density and temperature near Titan and in some regions of Saturn's magnetosphere. RPWS studies the configuration of Saturn's magnetic field and its relationship to Saturn Kilometric Radiation (SKR), as well as monitoring and mapping Saturn's ionosphere, plasma, and lightning from Saturn's (and possibly Titan's) atmosphere.[9]


  • Radio Science Subsystem (RSS)

    The Radio Science Subsystem (RSS) is a remote sensing instrument that uses radio antennas on Earth to observe the way radio signals from the spacecraft change as they are sent through objects, such as Titan's atmosphere or Saturn's rings, or even behind the sun. The RSS also studies the compositions, pressures and temperatures of atmospheres and ionospheres, radial structure and particle size distribution within rings, body and system masses and gravitational waves. The instrument uses the spacecraft X-band communication link as well as S-band downlink and Ka-band uplink and downlink.[10]


  • Ultraviolet Imaging Spectrograph (UVIS)

    The Ultraviolet Imaging Spectrograph (UVIS) is a remote sensing instrument that captures images of the ultraviolet light reflected off an object, such as the clouds of Saturn and/or its rings, to learn more about their structure and composition. Designed to measure ultraviolet light over wavelengths from 55.8 to 190 nm, this instrument is also a valuable tool to help determine the composition, distribution, aerosol particle content and temperatures of their atmospheres. This sensitive instrument is different from other types of spectrometers because it can take both spectral and spatial readings. It is particularly adept at determining the composition of gases. Spatial observations take a wide-by-narrow view, only one pixel tall and 60 pixels across. The spectral dimension is 1,024 pixels per spatial pixel. Additionally, it is capable of taking so many images that it can create movies to show the ways in which this material is moved around by other forces.[11]


  • Visible and Infrared Mapping Spectrometer (VIMS)

    The Visible and Infrared Mapping Spectrometer (VIMS) is a remote sensing instrument that is actually made up of two cameras in one: one is used to measure visible wavelengths, the other infrared. VIMS captures images using visible and infrared light to learn more about the composition of moon surfaces, the rings, and the atmospheres of Saturn and Titan. VIMS also observes the sunlight and starlight that passes through the rings to learn more about ring structure. VIMS is designed to measure reflected and emitted radiation from atmospheres, rings and surfaces over wavelengths from 0.35 to 5.1 mm. It will also help determine the compositions, temperatures and structures of these objects. With VIMS, scientists also plan to perform long-term studies of cloud movement and morphology in the Saturn system, to determine the planet's weather patterns.[12]


  • So how does String/M theory change the way we see?


    The calorimeter design for GLAST produces flashes of light that are used to determine how much energy is in each gamma-ray. A calorimeter ("calorie-meter") is a device that measures the energy (heat: calor) of a particle when it is totally absorbed.


    Smolin added his contribution to the string theory discussion on the new Cosmicvariance.com site that has been created by a group of people that offer perspective. In this case Sean Carroll posted a thread on Two Cheers for String theory, provoked some iteresting responses by minds who are at the forefront of these conversations.

    I responded to this becuase I had been following both avenues Smolin spoke too, so I'll put my comment here as well.

    This topic thread was develope from my reactions based on those who call people who are trying hard to integrate views of the natural world with the physics ideology of the topic of Strings?M theory, these fellows present. If they can not show us these new views as Smolin offers for inspection then what use the models and theories if no onne wants to se these work in the world we undrstand well by seeing around us?

    While some people are looking for consistant means of determinations, others apply "conceptual situations" and bring forth comprehension of a kind. Now to this degree, that "gluonic perception is being adjusted" to see these values. The Smolins and others understood well the limitation of these views? Are there any?


    Radio sounds from the source

    All of the structures we observe in Saturn's radio spectrum are giving us clues about what might be going on in the source of the radio emissions above Saturn's auroras," said Dr. Bill Kurth, deputy principal investigator for the instrument. He is with the University of Iowa, Iowa City. Kurth made the discovery along with Principal Investigator Don Gurnett, a professor at the University. "We believe that the changing frequencies are related to tiny radio sources moving up and down along Saturn's magnetic field lines."


    Has Sound, Changed the way we See?

    Most of us understand the the aurora display do we not, and the resulting interactive play between the sun and the earth? The Auger experiment previously talked about and spoken too, by John Ellis, is a fine example of the diversity of interative features we can hope to see, as we examine the particle nature apart from the LHC rules of energy engagement, above and beyond the limits that have been imposed on us earthlings:)


    The Fly's Eye and the Oh My God Particle


    While the topic is produced for this conversation seems disjointed, the ideology of the string theorist is held to a boundry of thinking in my eyes that such a membrane( here I could link a toy model for comparison), and defined in this bubble context, as rudimentry as it appears in my mind's eye, it follows the developemental processes we see from the eulicidation Einstein offered us by joining Maxwell into the process unfolding in nature and to see the effect of any bulk production as a necessary step beyond the boudaries of this bubble?


    Now in contrast I see the soapy bubble and light refraction dispalyed in such a lovely continuous flow over it's surface, that to me, it does not make sense if such auroric dispalyes are not to give us new ideas about the interactive feature of the sun with earth? Conceptually, thes ideas of hitting metal plates and such present new ideas in how dispersion across that plate could represent other ideas. What are those. Wel that's what I am trying to do is free the mind from th econstraints we had put on it in sucha strick language accompany those that step ahead of us in their own specualtions educationally followed doctrine. What new light and thinking patterns follow these people?

    The auroral ionosphere is a natural emitter of radio waves, and many of these emissions are observable at ground level. Several types of radio emissions have been well documented using a variety of ground-based, stepped-frequency receivers (see reviews by LaBelle [1989] and LaBelle and Weatherwax, [1992]). In particular, auroral roar is a relatively narrowband emission at roughly 2 and 3 times the local electron cyclotron frequency ( ) [Kellogg and Monson, 1979; Kellogg and Monson, 1984; Weatherwax et al., 1993, 1995]. Much effort has been made in characterizing the seasonal, diurnal, and spectral characteristics of auroral roar to aid in determining its generation mechanism [e.g., Weatherwax et al., 1995.

    Gamma Ray Detection

    A important point here is that there should be coincidental features in gamma ray detection, that should align with LIGO detectors?

    Why are two installations necessary?


    At least two detectors located at widely separated sites are essential for the unequivocal detection of gravitational waves. Local phenomena such as micro-earthquakes, acoustic noise, and laser fluctuations can cause a disturbance at one site, simulating a gravitational wave event, but such disturbances are unlikely to happen simultaneously at widely separated sites.


    Lubos said::
    The LIGO collaboration informed that the second science run did not detect any gravitational waves. The results follow from 10-day-long observations in early 2003 (two more science runs have been made ever since)


    A current blackhole has been detected and so should LIGO detect it. So how long should we wait if findings are only now being conisdered from 2003 run?

    Scientists have detected a flash of light from across the Galaxy so powerful that it bounced off the Moon and lit up the Earth's upper atmosphere. The flash was brighter than anything ever detected from beyond our Solar System and lasted over a tenth of a second. NASA and European satellites and many radio telescopes detected the flash and its aftermath on December 27, 2004. Two science teams report about this event at a special press event today at NASA headquarters.


    Journey to a Black Hole

    A direct image of gravity at its extreme will be of fundamental importance to Physics. Yet imaging a black hole requires a million times improvement over Chandra. That's a big step. Over the next 20 years, the Cosmic Journeys missions will take us closer and closer to a black hole though the power of resolution. Each successive mission will further us in our journey by 10- or 100-fold increases in resolution, step by step as we approach our goal of zooming in a million times closer. And each stop along the way will bring us new understandings of the nature of matter and energy.

    GLAST is a gamma-ray observatory mission that will observe jets of particles that shoot away in opposite regions from a supermassive black hole at near the speed of light. We do not fully understand how a black hole, which is known for pulling matter in, can generate high-speed jets that stretch out for billions of miles. Galaxies that harbor black holes with a jet aimed in our direction are called blazars, as opposed to quasars, which have their jets aimed in other directions. GLAST, up to 50 times more sensitive than previous gamma-ray observatories, will stare down the barrel of these jets to unlock the mechanism of how the enigmatic jets form. The Constellation-X mission will probe the inner disk of matter swirling into a black hole, using spectroscopy to journey 1,000 times closer to a black hole than any other mission before it. With such resolution, Constellation-X will be able to measure the mass and spin of black holes, two key properties. This X-ray mission will also map the distortions of space-time predicted by Einstein. Constellation-X draws its superior resolution by pooling the resources of four X-ray satellites orbiting in unison into one massive X-ray telescope. The ARISE mission will produce radio-wave images from the base of supermassive black hole jets with resolution 100,000 times sharper than Hubble. Such unprecedented resolution can reveal how black holes are fed and how jets are created. ARISE will attain this resolution through interferometry. This technique is used today with land-based radio telescopes. Smaller radio telescopes spread out on land -- perhaps one mile apart -- can work together to generate a single, huge radio telescope with the collecting power of a one-mile radio dish. ARISE will utilize one large radio telescope in space with many other radio telescopes on Earth, bringing what is now a land-based technology to new heights

    New NASA Satellite to Study Black Hole Birth and Gamma Ray Bursts


    The Swift observatory comprises three telescopes, which work in tandem to provide rapid identification and multi- wavelength follow-up of GRBs and their afterglows. Within 20 to 75 seconds of a detected GRB, the observatory will rotate autonomously, so the onboard X-ray and optical telescopes can view the burst. The afterglows will be monitored over their durations, and the data will be rapidly released to the public.
