The Colour of Gravity

Boy do I miss be able to do some of the bloggey work and research information. :)

The thought on the color of gravity has been talked about on my site before. From a metaphysical standpoint, philosophical, I sometimes wonder, that if the choices we make are forever sealed in our emotive states, then how weak a measure it would be for us to question what the color of gravity would mean in relation.

Rimimgton's Colour Organ-Professor Rimington's home demonstrations must have been unforgettable. The Colour Organ was some ten feet high, with a five octave keyboard which was similar to that of a church organ, being controlled by stops. A line of "colour keys" was situated above the conventional (sound) keyboard, and connected to a lens-and-filters system, so that "colour" was "played". Best effects were secured when the sound and colour were played from separate keyboards.

I mean if we were to ever have been able to see the colour of our mental and emotive states, what would this plethoria of colour actually look like? What realms would we have been assigned too, by our own natures and constitutions, that we would see only what we are allowed to see, and nothing more?

As if being held to this "frame of reference?" From a coordinated state of affairs, I always liked Greg Egan's animation examples.

Isostatic Adjustment is Why Planets are Round?

Conclusion:The state of mind of the observer plays a crucial role in the perception of time.Einstein
See here.

If we thought of the "Colour of Gravity" posted here, what values could you assign any materials that arise from the centre out? Gravity would have it's way with these materials for us to assign them to their unique ordering?

The Power of Myth With Bill Moyers, by Joseph Campbell , Introduction that Bill Moyers writes,

"Campbell was no pessimist. He believed there is a "point of wisdom beyond the conflicts of illusion and truth by which lives can be put back together again." Finding it is the "prime question of the time." In his final years he was striving for a new synthesis of science and spirit. "The shift from a geocentric to a heliocentric world view," he wrote after the astronauts touched the moon, "seemed to have removed man from the center-and the center seemed so important...


That we may say, the minerals on the moon have been assigned their valuation too? I would say it's the colour of gravity that we had assigned all of humanities thoughts and where is man/woman's centre?

Image: NASA/JPL-
Planets are round because their gravitational field acts as though it originates from the center of the body and pulls everything toward it. With its large body and internal heating from radioactive elements, a planet behaves like a fluid, and over long periods of time succumbs to the gravitational pull from its center of gravity. The only way to get all the mass as close to planet's center of gravity as possible is to form a sphere. The technical name for this process is "isostatic adjustment."

With much smaller bodies, such as the 20-kilometer asteroids we have seen in recent spacecraft images, the gravitational pull is too weak to overcome the asteroid's mechanical strength. As a result, these bodies do not form spheres. Rather they maintain irregular, fragmentary shapes.


By using Grace here, and the way we look at earth now, we get a better sense of what the actual shape of the earth is. WE had all thought it looked so round from space, that under a "time variable measure" we knew better. We knew that the variations in topographical locations would reveal something unique in relation to gravity. It took Grace to do that



Our work is about comparing the data we collect in the STAR detector with modern calculations, so that we can write down equations on paper that exactly describe how the quark-gluon plasma behaves," says Jerome Lauret from Brookhaven National Laboratory. "One of the most important assumptions we've made is that, for very intense collisions, the quark-gluon plasma behaves according to hydrodynamic calculations in which the matter is like a liquid that flows with no viscosity whatsoever."
See more here

The Moon Clementine-Color ratio image of Aristarchus Crater on the Moon-Clementine color ratio composite image of Aristarchus Crater on the Moon. This 42 km diameter crater is located on the corner of the Aristarchus plateau, at 24 N, 47 W. Ejecta from the plateau is visible as the blue material at the upper left (northwest), while material excavated from the Oceanus Procellarum area is the reddish color to the lower right (southeast). The colors in this image can be used to ascertain compositional properties of the materials making up the deep strata of these two regions. (Clementine, USGS slide 11)

It is not so far fetched for the mind to think of the planet in question, as to it's roundness, or, the moon in relation to how we see those impact craters on it's surface. "The moon" quite revealing in the mineralogical decor for us. So there are two things to consider here.

From the "boundary" of the planet "inward" and from the "centre" of the planet "outward."

Gravity Experiments

No matter how absurd? :)

From a early age, young Albert showed great interest in the world around him. When he was five years old, his father gave him a compass, and the child was enchanted by the device and intrigued by the fact the needle followed a invisible field to point always in the direction of the north pole.Reminiscing in old age, Einstein mentioned this incident as one of the factors that perhaps motivated him years later to study the gravitational field. God's Equation, by Amir D. Aczel, Pg 14

So you fast forward a few years and what have you got with regards to nature accompany the man who fell off his roof?


Albert Einstein (1879–1955)

One part of the theory of Relativity was inspired when a painter fell off a roof. Einstein found out that while the painter was falling freely, he felt weightless. This led Einstein to realize that gravity was a form of inertia, a result of the way things moved through space - and General Relativity was born.


So it is "by accident" General Relativity was born? Having things happen within context of natures own timing leaves one with some impressions it seems? How often have you noticed the outside world while you are doing your abstract thinking? What is so conducive that the open doorway allowed this other information to flow quite freely into the mind's cavity? You happebn to be working woth natures and it's puzzles yet what use any of these geometrical forms?

Plato:
It is of course with some concern that any scientific mind, held to the established rules of his organizational, "motto of acceptance of the stringent rules of science" would allow such room, as to imbue the human being with qualities greater then, the value assigned to subjective valuations.


So having faced the idea of the "gravitonic condensation" what use this idea(a painting) in terms of what we see as we spell out the differences between micro lensing and "gravitational lensing" how light travels from those distant points in the universe?

This miniature drop tower is used by Microgravity man and others to demonstrate the effects of reduced gravity on physical and chemical phenomena that are normally masked by Earth's gravity.

I know about people distancing themselves from what may indeed trouble them, as if, one presented some "anomaly in nature" that I/you may have never seen before. Do I take them on face value for what we had know of them? While reading their blog over the years, months, days, what conclusion had you reached?? Superman, Spiderman, and Captain Marvel comics which glorify the hero? Spheres, as bubbles in gravity free environment are always a nice thing to consider.

A bubble is a minimal-energy surface of the type that is formed by soap film.

I selected Kuhn because I was speaking directly to what was evident in my own life. What was presented to me "as the experience" may have likewise captivated a young child of 5, while another is trouble by symmetry in a "qualitative style."

I began my own investigations, and this set the course for my life to understand what had happened. How ever absurd one may find my statement in the previous post, it is a fact that I do not know how it was accomplished, but I did indeed see the effect of the person free of what we know as gravity holding the individual to her bosom.

So you have this statement. Q9 said,"the outer gravity which keeps our feet firmly on the ground."



So how was I suppose to react given the circumstances I had mentioned? If I said the mind was involved in the process "what proof do I have" that the person could indeed do the things that defy, what a frog may do for one who likes to wear shoes that make them light on their feet?

So any concept which had spoken about gravity, to one extent or another, has entered my research, for me to find some way that would allow such a thing to entertain the sceptic, as well as take the form of flowery pot comments. "Concepts" as foolish as the bulk?

Of course I want to know what happen in the way that young Einstein wondered about the mystery of nature assigned to that needle. We know now don't we? Oh, gravity is weak here on earth? Weaker then the magnet that is attached itself to the fridge.

So when gravity had ever been strong? How strong, that it could reach only so far?

Angels and Demons on a Pinhead

"Observations always involve theory."Edwin Hubble
Curvature Parameters

Of course I had to point to the cosmological understanding that took us to this "geometrical understanding of things that are large." But this is to be short, while I crunch the thoughts of the process to the pinhead. You can follow the "picture links" and learn more on your own time.


Calabi-Yau manifold (3D projection made with Mathematica)-
In either case, gravity acting in the hidden dimensions affects other non-gravitational forces such as electromagnetism. In fact, Kaluza and Klein's early work demonstrated that general relativity with five large dimensions and one small dimension actually predicts the existence of electromagnetism. However, because of the nature of Calabi-Yau manifolds, no new forces appear from the small dimensions, but their shape has a profound effect on how the forces between the strings appear in our four dimensional universe. In principle, therefore, it is possible to deduce the nature of those extra dimensions by requiring consistency with the standard model, but this is not yet a practical possibility. It is also possible to extract information regarding the hidden dimensions by precision tests of gravity, but so far these have only put upper limitations on the size of such hidden dimensions.


How many would have thought that such a micro-perspective could have been ever be taken down to "this level" and found an analogy that is suitable? You needed something more here to consider, yet, I will call it "angel and demons" for those who like the mystery.


Image: courtesy Andrew J. Hanson, Indiana University-A computer-generated rendering of a possible six-dimensional geometry similar to those studied by UW-Madison physicist Gary Shiu.

I will try and spell out what is happening at such a microperspective level. You might wonder, how did such ideas become what is, "the good and evil of the world" is really a part of the dynamics that we see geometrically enhanced, as we delve ever deeper into this mystery of reductionism and such. On how, we may look at cosmology that "is different" with this perspective.

Energy "is" Gravitationally Related

At some point, those considering "all this energy" and the way reduction is assigned to the energy at all levels, what shall any calorimetric pick up as such collision processes seek to define "every contact" as we want to "map the pinhead" accordingly?

Lubos Motl saids that he sees the relation to such dynamical situations as "fruitful research" toward the understanding of the cosmological descriptions implied from such micro states. To have it listed according to a "geometrical perspective" we might be able to assign each universe? Okay! He did not say that exactly, so check into his blog entry for an update.

I'd like to thank Quasar9 for reporting on this as well.

Orbitals



My thoughts have been there toward reductionism's more cosmological counterpart for some time now. So I enjoy, that the views that I have had about the microperspective have indeed been sanctioned at some science level according to the scientist in the know. Yes, I can prove my thoughts here for you, so you know what I mean.


The star Eta Carina is ejecting a pair of huge lobes that form a "propeller" shape. Jet-like structures are emanating from the center (or "waist"), where the star (quite small on this scale) is located.


Now it is indeed a "greater depth of perception" that asks us to delve into the microperspective of string world. How is it the cosmological world can have such similarities, while the story of the Calabi Yau, makes itself a headlight news current in the research of string theory?

The First Few Microseconds, by Michael Riordan and Willaim A. Zajc
During those early moments, matter was an ultrahot, superdense brew of particles called quarks and gluons rushing hither and thither and crashing willy-nilly into one another. A sprinkling of electrons, photons and other light elementary particles seasoned the soup. This mixture had a temperature in the trillions of degrees, more than 100,000 times hotter than the sun's core.

    No Extra Dimensions Yet?

    Turning back to gravity, the extra-dimensions model stems from theoretical research into (mem)brane theories, the multidimensional successors to string theories (April 1999 p13). One remarkable property of these models is that they show that it is quite natural and consistent for electromagnetism, the weak force and the inter-quark force to be confined to a brane while gravity acts in a larger number of spatial dimensions.
    The requirement of correctly reproducing Newton's constant, G, at long distances leads to the size of the extra dimensions in which gravity is free to act being related to the number of extra dimensions.



    New physics experience might reveal more dimensions in the Universe than meets the eyeSee Here

    Amazing isn't it that EOT-WASH GROUP would consider themselves as challenging the experimental basis of string theory thinking. If one did not see into the nature of that "dynamical world" what value would have ever been reached if there was no separation in the value of the "r distance?" No "varying energy valuation" in the strong force.


    Fig. 1. In quantum chromodynamics, a confining flux tube forms between distant static charges. This leads to quark confinement - the potential energy between (in this case) a quark and an antiquark increases linearly with the distance between them.See Here.

    If a "Q to Q" measure is considered and a "active consideration evident" in this exchange of a "r value," then why would they think the gravitational considerations would not have ever made sense in the distances of extra dimensions of 44 micrometres or larger?

    By increasing this distance, the gravitational considerations are very important in terms of the energy valuation given as the "q to q" is moved apart. The energy is directly relate to the gravitational considerations?


    Image: EOT-WASH GROUP, UNIVERSITY OF WASHINGTON

    Discovering extra dimensions with the relatively huge size of a few micrometers would offer spectacular confirmation for string theory, the still unproved body of equations that may unify gravity with the normally incompatible realm of quantum physics. "Even though we haven't seen anything, these results put boundaries on what people can legitimately propose," says experimental physicist and study author Eric Adelberger of the University of Washington. "Testing the inverse square law [meaning Newton's law of gravity] is the bombproof way to look for extra dimensions.
    "


    some physicists proposed that string theory might cause gravity to grow stronger at such distances if the universe came with relatively big extra dimensions of micrometers in width......Sundrum says that if extra dimensions failed to turn up at that distance, it would likely prune off that branch of string theory.

    Newton's inverse-square (1/r2) law

    The standard model of particle physics is a self-contained picture of fundamental particles and their interactions. Physicists, on a journey from solid matter to quarks and gluons, via atoms and nuclear matter, may have reached the foundation level of fields and particles. But have we reached bedrock, or is there something deeper? Savas Dimopoulos


    While in the post previous to this I gave some indication of the gravity from the cosmological point of view, I then took it down to the particle collisions. I again reiterate this, in this post as well.


    Source-detector configuration for the 1-m 1/r2 test
    Newton's inverse-square (1/r2) law is a cornerstone of General Relativity. However, this law has been challenged by many modern theories of gravity and particle physics. The supergravity and unified field theories often run into a new short-range force, with an accompanying new particle, which should appear as a violation of the 1/r2 law. More recently, a possible violation of the 1/r2 law in the range below 1 mm was suggested by string theories with extra dimensions.



    Gravity: Another Example of a 1/R2 Law
    Two masses at a given distance place equal and opposite forces of attraction on one another. The magnitude of this force of attraction is given by:




    where G is the universal gravitation constant (6.67 X 10-11 Nm2/kg2), m1 is the mass of the first object in kilograms, m2 is the mass of the second object in kilograms, and r is the distance between the centers of the two masses, in meters.


    It is not without thinking here that what you thought of the "microstate blackhole," could have found it's relevance in the temperatures reached, when seen at this level?


    Fig. 1. In quantum chromodynamics, a confining flux tube forms between distant static charges. This leads to quark confinement - the potential energy between (in this case) a quark and an antiquark increases linearly with the distance between them.
    The ideal experimental test of this new feature of QCD would be to study the flux tube of figure 1 directly by anchoring a quark and antiquark several femtometres apart and examining the flux tube between them. In such ideal circumstances, one of the characteristics of the gluonic flux tube would be the model-independent spectrum shown in figure 2. The excitation energy is p/r because the flux tube's mass is entirely due to its stored energy. There are two initially excited longest wavelength vibrations with identical energies because the motion of the flux tube is in the two symmetrical dimensions perpendicular to its length.


    You ever hear of the term, "you can't hit the broad side of a barn?" WEll lets think about this when it comes to the measures of femtometres and such. Classically old, it was not witout some direction in thinking that one could be taken down to certain measures for those same considerations. Barn Yard?

    Origin of the (classified) barn

    In the luminosity lexicon, a picobarn is one trillionth (10-12) of a barn, and a femtobarn is one quadrillionth (10-15) of a barn... but what's a barn? The distinctive and amusing term originated with two Purdue University physicists working on the Manhattan Project in 1942—and it was classified information by the US government until after World War II.

    A History of Physics at Purdue (Gartenhaus, Tubis, Cassidy, and Bray) cites the July 1972 issue of Physics Today in which Marshall Halloway and Charles Baker write of tossing around ideas over dinner until arriving at "barn" to describe the typical nuclear cross section of 10-24 cm2, the effective target area that a nuclear particle represents in a collision. Dining in the Purdue Memorial Union, back in Lafayette, Indiana, Halloway and Baker dismissed "Oppenheimer" and "Bethe" as candidates, then considered John Manley, director of the Purdue group at Los Alamos. They decided "Manley" was too long, and then, as the authors put it in the Physics Today article to:


    So here we are looking at what the EOT-WASH GROUP is doing? What is "compactification" in line with any thinking, that the world around us from a cosmological point of view is large(large circle), and that amidst it's reality, exists this finer world of particulars that "we'd only imagine" while the measures to it's finest(small circle) was produce and then energies assigned.

    It would be as if you looked at the cosmos and never thought about it constituents "bits and pieces," which make up those cosmological processes. Yet, for me, "circles within circles" would have made me wonder which circle represented which part of the views at any one time, whilst we speak about these energies from one perspective to the next.

    Savas Dimopoulos:At close encounter the particles can exchange gravitons via the two extra dimensions, which changes the force law at very short distances. Instead of the "Newtonian inverse square law" you’ll have an inverse fourth power law. This signature is being looked for in the ongoing experiments.


    .....and more here for how perspectve can change once you give a direction in which to think about.

    Savas Dimopoulos:At first we faced denial. We had deliberately used the word "sub-millimeter" in our first paper. Physicists were surprised, to say the least, that such a thing was not already excluded experimentally. I remember a stage in 1998 when colleagues wondered if we had not forgotten some crucial experiment. We were not discouraged. No! We gave talks on the ideas, and by July 1998 had analyzed the laboratory and cosmological constraints. That paper marked a sea-change in opinion: physicists began to think this was an interesting idea. By the fall of 1998 we were showing how to do real physics. Now several study groups are taking us very seriously: the high citation rates speak for themselves.
    Personally I am not surprised by the reaction. Revolutionary ideas go through a cycle: denial, followed by "okay it is consistent but can you do anything with it?" and finally, once you show how to do real physics, you may get the third phase where many physicists become interested in the field. The same thing happened to me and Giorgi back in 1981 when we first proposed the supersymmetric extension of the standard model of particle physics. Initially there were the usual skeptics but now it is completely accepted.
    Oddly, for me, the major competitor to these proposals for extra dimensions is the supersymmetry extension. But let's recall some of the disadvantages of the standard model. First, it shuts out gravity. Second, it has 18 free parameters, many of them very small. Third, the vacuum energy is 120 orders of magnitude larger than what you would naively guess from the standard model.
    Proposing extra dimensions to space is a drastic step. But once you have the extra space you can attribute the smallness of some quantities to the statement that their origin is somewhere far away inside space, just as an astronomer might attribute the faintness of a galaxy to its large distance. For example, maybe the smallness of the electron mass arises because its origin is far away inside the extra dimensions.
    My view is that both of the big ideas I have worked on are testable in the next decade by LHC. The two frameworks have complementary features. I'm greatly looking forward to the outcome


    Make sure you look at the "compactification" label to the right index

    Gravity Free Environment on Earth

    It's taken some time from a layman perspective to try and "place this experiment" in a setting that helps orientate views. Well, at least in my case. :)

    So here is a "guide below" that may seem trivial to some, yet, directed to the "microperspective" on this experiment, speak to cosmology as well. While it may seem easy from a "cosmological standpoint" gravities "effect" is of some importance in "condense matter views."

    A "Top/down approach" pointing you toward LHC and the "anomaly of relativity" in the perfect fluid, seems like going "full circle?"

    See:"Cosmic Variance"

    Anyway to the essence of what has been instigated by the post of Seans, and what came about from the "Aerogel and Stardust" Post.


    Microgravity Science Glove Box-The MSG will enable astronauts on board the ISS to perform a wide variety of materials, combustion, fluids and biotechnology experiments as well as investigations in the microgravity environment. It can also accommodate minor repairs and servicing of hardware requiring a controlled working environment. The facility offers users a wide range of innovative, utilization alternatives from manual control by astronauts via laptop computers to fully automated and remote control from Earth (telescience). A permanent data exchange link with ground stations is also ensured.The MSG will be integrated and used in the US Destiny Laboratory for a projected operational period of ten years.ESA is planning to use the facility for European experiments. The first time MSG will be used by a European astronaut to perform European experiments will be during a Soyuz taxi flight mission in October 2002. ESA's Belgian astronaut Frank De Winne will perform four different experiments in the MSG in the field of protein crystallization, zeolites crystallization, combustion and fluid science.

    Why is it we cannot create this environment, other then, the method described in terms of the drop tower, or, out in space? What ways do you know that such simulation can be developed to move the ideas of product development "done there in space." To make it feasible to create the condense matter states that are purer free from the effect of gravity on earth.

    “On Earth, buoyancy continuously deforms and moves fluids in complex manners, making it difficult to study how materials that solidify from the melt form semiconductors and other products,” said Dr. Aleksandar Ostrogorsky, the SUBSA principal investigator who also teaches and conducts research at the Rensselaer Polytechnic Institute in Troy, N.Y. “In microgravity, the fluids are almost stagnant, resembling solids. The absence of motion makes it easier to observe and mathematically describe what is occurring when the crystals are melted, and how the materials solidify to form a new crystal.”


    The idea occurred to me today to find a way in which to "create the environment" that is conducive to perfecting the "purity of alignment of substances" in a gravity free environment. I mentioned the aerogel in the previous article and how developing that product in space gives the product superior qualities, that one might not have here on earth.


    Aircraft: A two-engine turbofan aircraft similar to the McDonnell-Douglas DC-9
    A typical mission is 2 to 3 hours long and consists of 40 to 50 parabolas. These parabolas can be flown in succession or with short breaks between maneuvers to reconfigure test equipment. The Reduced Gravity Office provides scheduling, test coordination, and in-flight direction for the test programs.


    So, we create the conditions for it. Whether it be the Space Shuttle, the Airplane or the Miniature Drop Tower.

    NASA's "Weightless Wonder" KC-135a Reduced Gravity Laboratory

    By comparing the results from fuel vaporization in a reduced-gravity environment with those under normal conditions, the students aim to gain a better understanding of how fuel droplets behave under different conditions to optimize the fuel injection process. The findings may be used in helping promote changes in engine design while improving efficiency and reducing emissions.


    By understanding the process from "space to earth" we see where ingenuity of mind applies the differences of "time clocks" and such.


    As one of the fields which obey the general inverse square law, the gravity field can be put in the form shown above, showing that the acceleration of gravity, g, is an expression of the intensity of the gravity field.


    In a manner that "it's effects" in relation to gravity may be considered from a cosmological and micro-gravity perspective, in relation to "Inverse Square law( I use sound in the example, but click on the image provided)" and "Inverse Fourth Power Law."


    This miniature drop tower is used by Microgravity man and others to demonstrate the effects of reduced gravity on physical and chemical phenomena that are normally masked by Earth's gravity.


    So here we are "to the experiment" in a microperspective that is currently being explored.

    Eric Adelberger on Aug 12th, 2005 at 2:37 pm

    Please don’t get too excited yet about rumors concerning the Eot-Wash test of the 1/r^2 law. We can exclude gravitational strength (|alpha|=1) Yukawa violations of the 1/r^2 law for lambda>80 microns at 95% confidence. It is true that we are seeing an anomaly at shorter length scales but we have to show first that the anomaly is not some experimental artifact. Then, if it holds up, we have to check if the anomaly is due to new fundamental physics or to some subtle electromagnetic effect that penetrates our conducting shield. We are now checking for experimental artifacts by making a small change to our apparatus that causes a big change in the Newtonian signal but should have essentially no effect on a short-range anomaly. Then we will replace our molybdenum detector ring with an aluminum one. This will reduce any signal from interactions coupled to mass, but will have little effect on subtle electromagnetic backgrounds. These experiments are tricky and measure very small forces. It takes time to get them right. We will not be able to say anything definite about the anomaly for several months at least.

    Hubble Maps the Cosmic Web of "Clumpy" Dark Matter in 3-D


    Three-Dimensional Distribution of Dark Matter in the Universe
    This three-dimensional map offers a first look at the web-like large-scale distribution of dark matter, an invisible form of matter that accounts for most of the universe's mass. This milestone takes astronomers from inference to direct observation of dark matter's influence in the universe. Because of the finite speed of light, regions furthest away are also seen as they existed a long time ago. The map stretches halfway back in time to the beginning of the universe.

    The map reveals a loose network of dark matter filaments, gradually collapsing under the relentless pull of gravity, and growing clumpier over time. This confirms theories of how structure formed in our evolving universe, which has transitioned from a comparatively smooth distribution of matter at the time of the big bang. The dark matter filaments began to form first and provided an underlying scaffolding for the subsequent construction of stars and galaxies from ordinary matter. Without dark matter, there would have been insufficient mass in the universe for structures to collapse and galaxies to form.


    Part of this reporting is the way in which one could look at the Cosmos and see the gravitational relationships, as one might see it in relation to "Lagrangian views" in the Sun Earth Relation.


    Diagram of the Lagrange Point gravitational forces associated with the Sun-Earth system.


    Make sure you click on the image for further information. Mouseovers as your cursor is placed over images or worded links are equally important. You learn about satellites and the way they travel through these holes.

    While one can see "dark matter" in terms of it's constraints, what of "dark energy" as it makes it way through those holes? This reveals the expansionary nature in terms of dark energy being repelled, whether you like to think so or not. This explains the dark energy developing free of the dark matter constraints and explains the state of our universe.


    LSST Homepage background image. (Image credit: LSST Corporation, Bryn Feldman) Design of LSST Telescope dome and local facilities, current as of January 2007. Google Inc. has joined with nineteen other organizations to build the Large Synoptic Survey Telescope, scheduled to see first light atop Cerro PachĂłn in Chile in 2013.
    The Large Synoptic Survey Telescope (LSST) is a proposed ground-based 8.4-meter, 10 square-degree-field telescope that will provide digital imaging of faint astronomical objects across the entire sky, night after night. In a relentless campaign of 15 second exposures, LSST will cover the available sky every three nights, opening a movie-like window on objects that change or move on rapid timescales: exploding supernovae, potentially hazardous near-Earth asteroids, and distant Kuiper Belt Objects. The superb images from the LSST will also be used to trace billions of remote galaxies and measure the distortions in their shapes produced by lumps of Dark Matter, providing multiple tests of the mysterious Dark Energy.



    Two simulations of strong lensing by a massive cluster of galaxies. In the upper image, all the dark matter is clumped around individual cluster galaxies (orange), causing a particular distortion of the background galaxies (white and blue). In the lower image, the same amount of mass is more smoothly distributed over the cluster, causing a very different distortion pattern.


    Here in this post the example of "how one may see" is further expounded upon to show how dark matter and dark energy are in action as a 90% aspect of the cosmos, while the remaining 10% is a discrete measure of what is cosmologically matter orientated. We don't loose sight of these relationships, but are helped to further develope them in terms of this gravitational relationship.

    Images or Numbers By Themself

    “Mathematicians have tried in vain to this day to discover some order in the sequence of prime numbers, and we have reason to believe that it is a mystery into which the mind will never penetrate” (cited by Ivars Peterson in Science News, 5/4/2002).


    I have an idea in mind here that will be slow to show because I am not sure how it is supposed to be laid out. So maybe by showing these numbers by them self? What use, if one did not, or was not able to see in another way?


    Figure 22.10: Double slit diffraction


    I looked at the "straight lines" of Thomas Young's trajectories of photon emission and while quite understandably shown to be of consequence in this post "Interference." I was more interested in how something could start off in one place and do this rotation of sorts, and then come back for examination again in the real world. The Spectrum

    What a novel idea to have the methods used by the predecessors like Maxwell, to have been united from Faraday's principals? To have Maxwell's equation Gaussian in interpretation of Riemann geometry, somehow, united by the geometries of Einstein and defined as gravity?


    But it is also in mind "that the image" has to be put here also before the numbers can show them self. What use these numbers if I do not transcend them to what they can imply in images, to know that the thinking here has to be orientated in such a way that what was simple and straight forward, could have non-euclidean orientations about it?


    Michael Faraday (September 22, 1791 – August 25, 1867) was a British scientist (a physicist and chemist) who contributed significantly to the fields of electromagnetism and electrochemistry.


    So one reads history in a lot of ways to learn of what has manifested into todays thinking. What lead from "Gaussian coordinates in an "non-euclidean way" to know that it had it's relation in today's physics. To have it included in how we see the consequences of GR in the world. It had been brought together for our eyes in what the photon can do in the gravitational field.

    Our Evolution to Images


    The Albrecht Durer's Magic Square



    Ulam's Spiral



    Pascal's Triangle


    Evolve to What?

    Who was to know what Leonard Susskind was thinking when his mathematical mind was engaged in seeing this "rubber band" had some other comparative abstraction, as something of consequence in our world. Yet, people focus on what they like to focus on, other then what "lead the mind" to think the way they do?


    Poincaré Conjecture
    If we stretch a rubber band around the surface of an apple, then we can shrink it down to a point by moving it slowly, without tearing it and without allowing it to leave the surface. On the other hand, if we imagine that the same rubber band has somehow been stretched in the appropriate direction around a doughnut......


    I have to rest now.

    Symmetries Can be Chaotically Complex



    Imagine in an "action of a kind" you start off from one place. A photon travelling through a slit of Thomas Young's, to get through "a world" to the other side. Sounds like some fairy tale doesn't it? Yet, "the backdrop" is where you started?


    Thomas Young (June 14, 1773 – †May 10,1829)
    was an English scientist, researcher, physician and polymath. He is sometimes considered to be "the last person to know everything": that is, he was familiar with virtually all the contemporary Western academic knowledge at that point in history. Clearly this can never be verified, and other claimants to this title are Gottfried Leibniz, Leonardo da Vinci, Samuel Taylor Coleridge, Johann Wolfgang Goethe and Francis Bacon, among others. Young also wrote about various subjects to contemporary editions of the Encyclopedia Britannica. His learning was so prodigious in scope and breadth that he was popularly known as "Phenomenon Young."



    Simplistically this "massless entity" is affected by the "geometrics of gravity?" Is affected from it's "first light." All the way to some "other point in reality" to some image, called the spectrum.

    I am dreaming. I am walking down the street and there is this "N category cafe."

    Imagine walking off the street into this very public venue and seeing the philosophy shared is also held to certain constraints. :)Philosophy? Yes, we all have our "points of view."

    Travelling the Good Life with Ease

    So in this travel how is one to see this "curve of light" or "slide" and we get this sense of what gravity can do.

    Imagine indeed, "a hole cosmological related" in the three body problem, it has to travel through, and we get this sense of "lensing and distortion," abstractually gravitationally induced?



    So as we look at the cosmos what illusion is perpetrated on our minds as we look into the "great distance of measure" that somehow looking to the journey of "an event local," from our place on and about earth, has not been "chaotically entrained in some way, as we look deep into space?


    The Magic Square
    Plato:Like Pascal, one finds Albrecht has a unique trick, used by mathematicians to hide information and help, to exemplify greater contextual meaning. Now you have to remember I am a junior here in pre-established halls of learning, so later life does not allow me to venture into, and only allows intuitive trials poining to this solid understanding. I hope I am doing justice to learning.


    Moving in abstract spaces

    It was necessary to explain why I added "the image" to the right in my index.

    Some would think me so "esoteric" that I had somehow lost touch with the realities of science? That to follow any further discussion here "has to be announced" to save one's dignity? What ever?:)I am esoteric in that my views of the world come from a different place, not unlike your expression of where you had come from living your life. How would I come to know all that you are in a "single sentence." A single and very short equation? It's really not that easy is it?:)

    So I read you from all the things that you say and get the sense of who you are no different then what is implied in the language of poetic art implied carefully from choosing your words?

    Artistically Inclined?

    I tried to give some hint of the "ideas floating" around in my head. I understand quite well that my challenge has been to get those "images in my head" transmitted onto paper, in a way that one would not become confused as to what is being implied.

    So a good writer I may not be, a "not so good scientist" whose mathematics very ill equipped.

    Thus I am faced with these challenges in the new year? A "recognition" of trying to produce that clarity. Whether in "latex" the symbols of mathematics, it is quite a challenge for me, whilst all these things are still engaged in abstract views of reality.

    So someone like Clifford, may look at Robert by what he has written and say, "hey, my fellow scientists are indeed in trouble" from what Robert has learnt. So I Clifford will provide "the latex sandbox" for you to play in?

    It "appears" I am not alone. My struggle, are to be many a struggle.

    Art and the Abstract

    But to my amazement this morning in checking up the links associated of Clifford's, I was amazed to see the article of, Hooking Up Manifolds

    Now how interesting that what is being displayed there in terms of fun, mathematics, art, could have been so abstractly appealing? "Moving over these surfaces" in ways that one might never appreciated, had you not known about how one can look at the universe in the "two ways mentioned previously," and by simple experiment, transcend such things to art.

    N category and the Hydrogen spectrum


    Picture of the 1913 Bohr model of the atom showing the Balmer transition from n=3 to n=2. The electronic orbitals (shown as dashed black circles) are drawn to scale, with 1 inch = 1 Angstrom; note that the radius of the orbital increases quadratically with n. The electron is shown in blue, the nucleus in green, and the photon in red. The frequency ν of the photon can be determined from Planck's constant h and the change in energy ΔE between the two orbitals. For the 3-2 Balmer transition depicted here, the wavelength of the emitted photon is 656 nm.
    In atomic physics, the Bohr model depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus — similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity.

    Introduced by Niels Bohr in 1913, the model's key success was in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen; while the Rydberg formula had been known experimentally, it did not gain a theoretical underpinning until the Bohr model was introduced.

    The Bohr model is a primitive model of the hydrogen atom. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics, and thus may be considered to be an obsolete scientific theory. However, because of its simplicity, and its correct results for selected systems (see below for application), the Bohr model is still commonly taught to introduce students to quantum mechanics.


    For one to picture events in the cosmos, it is important that the spectral understanding of the events as they reveal themselves. So you look at these beautiful pictures and information taken from them allow us to see the elemental considerations of let's say the blue giants demise. What was that blue giant made up of in term sof it's elemental structure

    The quantum leaps are explained on the basis of Bohr's theory of atomic structure. From the Lyman series to the Brackett series, it can be seen that the energy applied forces the hydrogen electrons to a higher energy level by a quantum leap. They remain at this level very briefly and, after about 10-8s, they return to their initial or a lower level, emitting the excess energy in the form of photons (once again by a quantum leap).


    Lyman series
    Hydrogen atoms excited to luminescence emit characteristic spectra. On excitation, the electron of the hydrogen atom reaches a higher energy level. In this case, the electron is excited from the base state, with a principal quantum number of n = 1, to a level with a principal quantum number of n = 4. After an average dwell time of only about 10-8s, the electron returns to its initial state, releasing the excess energy in the form of a photon.
    The various transitions result in characteristic spectral lines with frequencies which can be calculated by f=R( 1/n2 - 1/m2 ) R = Rydberg constant.
    The lines of the Lyman series (n = 1) are located in the ultraviolet range of the spectrum. In this example, m can reach values of 2, 3 and 4 in succession.


    Balmer series
    Hydrogen atoms excited to luminescence emit characteristic spectra. On excitation, the electron of the hydrogen atom reaches a higher energy level. In this case, the electron is excited from the base state, with a principal quantum number of n = 1, to a level with a principal quantum number of n = 4. The Balmer series becomes visible if the electron first falls to an excited state with the principal quantum number of n = 2 before returning to its initial state.
    The various transitions result in characteristic spectral lines with frequencies which can be calculated by f=R( 1/n2 - 1/m2 ) R = Rydberg constant.
    The lines of the Balmer series (n = 2) are located in the visible range of the spectrum. In this example, m can reach values of 3, 4, 5, 6 and 7 in succession.


    Paschen series
    Hydrogen atoms excited to luminescence emit characteristic spectra. On excitation, the electron of the hydrogen atom reaches a higher energy level. In this case, the electron is excited from the base state, with a principal quantum number of n = 1, to a level with a principal quantum number of n = 7. The Paschen series becomes visible if the electron first falls to an excited state with the principal quantum number of n = 3 before returning to its initial state.
    The various transitions result in characteristic spectral lines with frequencies which can be calculated by f=R( 1/n2 - 1/m2 ) R = Rydberg constant.
    The lines of the Paschen series (n = 3) are located in the near infrared range of the spectrum. In this example, m can reach values of 4, 5, 6 and 7 in succession.


    Brackett series
    Hydrogen atoms excited to luminescence emit characteristic spectra. On excitation, the electron of the hydrogen atom reaches a higher energy level. In this case, the electron is excited from the base state, with a principal quantum number of n = 1, to a level with a principal quantum number of n = 8. The Brackett series becomes visible if the electron first falls to an excited state with the principal quantum number of n = 4 before returning to its initial state.
    The lines of the Brackett series (n = 4) are located in the infrared range of the spectrum. In this example, m can reach values of 5, 6, 7 and 8 in succession.

    Wolf-Rayet star

    While I have started off with the definition of the Wolf-Rayet star, the post ends in understanding the aspects of gravity and it's affects, as we look at what has become of these Wolf-Rayet stars in their desimination of it's constituent properties.

    Similar, "in my thinking" to the expansion of our universe?


    Artist's impression of a Wolf-Rayet star
    About 150 Wolf-Rayets are known in our own Milky Way Galaxy, about 100 are known in the Large Magellanic Cloud, while only 12 have been identified in the Small Magellanic Cloud. Wolf-Rayet stars were discovered spectroscopically in 1867 by the French astronomers Charles Wolf and Georges Rayet using visual spectrometery at Paris Observatory.


    There are some thoughts manifesting about how one may have see this energy of the Blue giant. It's as if the examples of what began with great force can loose it's momentum and dissipate very quickly(cosmic winds that blow the dust to different places)?


    Illustration of Cosmic Forces-Credit: NASA, ESA, and A. Feild (STScI)
    Scientists using NASA's Hubble Space Telescope have discovered that dark energy is not a new constituent of space, but rather has been present for most of the universe's history. Dark energy is a mysterious repulsive force that causes the universe to expand at an increasing rate.


    What if the Wolf-Rayet star does not produce the jets that are exemplified in the ideas which begin blackhole creation. Is this part of blackhole development somehow in it's demise, that we may see examples of the 150 Wolf-Rayets known in our own Milky Way as example of what they can become as blackholes, or not.

    Quark to quark Distance and the Metric

    If on such a grand scale how is it thoughts are held in my mind to microscopic proportions may not dominate as well within the periods of time the geometrics develop in the stars now known as Wolf-Rayet. So you use this cosmological model to exemplify micro perspective views in relation to high energy cosmological geometrics.



    Plato:
    "Lagrangian views" in relation may have been one result that comes quickly to my mind. Taking that chaldni plate and applying it to the universe today.


    While I had in the previous post talked about how Lagrangian views could dominate "two aspects of the universe," it is not without linking the idea of what begins as a strong gravitational force to hold the universe together, that over time, as the universe became dominated by the dark energy that the speeding up of inflation could have become pronounced by discovering the holes created in the distances between the planets and their moons. Between galaxies.



    I make fun above with the understanding of satellites travelling in our current universe in relation to planets and moons, as well as galaxies. To have taken this view down to WMAP proportions is just part of what I am trying to convey using very simplistic examples of how one may look at the universe, when gravity dominated the universe's expansion versus what has happened to the universe today in terms of speeding up.


    LOOP-DE-LOOP. The Genesis spacecraft's superhighway path took it to the Earth-sun gravitational-equilibrium point L1, where it made five "halo" orbits before swinging around L2 and heading home.Ross


    If the distances between galaxies have become greater, then what saids that that the ease with which the speeding up occurs is not without understanding that an equilibrium has been attained, from what was once dominate in gravity, to what becomes rapid expansion?

    This book describes a revolutionary new approach to determining low energy routes for spacecraft and comets by exploiting regions in space where motion is very sensitive (or chaotic). It also represents an ideal introductory text to celestial mechanics, dynamical systems, and dynamical astronomy. Bringing together wide-ranging research by others with his own original work, much of it new or previously unpublished, Edward Belbruno argues that regions supporting chaotic motions, termed weak stability boundaries, can be estimated. Although controversial until quite recently, this method was in fact first applied in 1991, when Belbruno used a new route developed from this theory to get a stray Japanese satellite back on course to the moon. This application provided a major verification of his theory, representing the first application of chaos to space travel.

    Since that time, the theory has been used in other space missions, and NASA is implementing new applications under Belbruno's direction. The use of invariant manifolds to find low energy orbits is another method here addressed. Recent work on estimating weak stability boundaries and related regions has also given mathematical insight into chaotic motion in the three-body problem. Belbruno further considers different capture and escape mechanisms, and resonance transitions.

    Providing a rigorous theoretical framework that incorporates both recent developments such as Aubrey-Mather theory and established fundamentals like Kolmogorov-Arnold-Moser theory, this book represents an indispensable resource for graduate students and researchers in the disciplines concerned as well as practitioners in fields such as aerospace engineering.
