Bacon is Shakespeare?

A modern day puzzle, becomes, blogger world signatures? Taken to a, "Whole....nother....Level.



Creativity? Ways in which we allow "information" to travel through? Play the game? Allow "ingenuity" as the "poetic river that flows" to the surface on you, from everything, or, the blank slate?

What kind of person are you who reveals them self in the words chosen, or the picture highlighted? Humor, as a deeper response for those who look beyond the confines of words, and laugh? We just intuitively get it?

What use that language?

Tragedies, where allowed "the other to speak," and let loose all the mournings of words lost, are covered by our heart's responses? "Released." The soul without it's burdens, carries on. Not really.

Describes the "fictional" in face of the real, while "highlighting the injustices" performing characters, as individual/politicians saved? Another place, and time?


Francis Bacon, De Dignitate et Augmentis Scientiarum, 1623.


The knowledge of Cyphering, hath drawne on with it a knowledge relative unto it, which is the knowledge of Discyphering, or of Discreting Cyphers, though a man were utterly ignorant of the Alphabet of the Cypher, and the Capitulations of secrecy past between the Parties. Certainly it is an Art which requires great paines and a good witt and is (as the other was) consecrate to the Counsels of Princes: yet notwithstanding by diligent prevision it may be made unprofitable, though, as things are, it be of great use. For if good and faithfull Cyphers were invented & practised, many of them would delude and forestall all the Cunning of the Decypherer, which yet are very apt and easie to be read or written: but the rawnesse and unskilfulnesse of Secretaries, and Clarks in the Courts of Princes, is such, that many times the greatest matters are Committed to futile and weake Cyphers.
But it may be, that in the enumeration, and, as it were, taxation of Arts, some may thinke that we goe about to make a great Muster-rowle of Sciences, that the multiplication of them may be more admired; when their number perchance may be displayed, but their forces in so short a Treatise can hardly be tried. But for our parts wee doe faithfully pursue our purpose, and in making this Globe of Sciences, we would not omitt the lesser and remoter Ilands. Neither have we (in our opinion) touched these Arts perfunctorily, though cursorily; but with a piercing stile extracted the marrow and pith of them out of a masse of matter. The judgement hereof we referre to those who are most able to judge of these Arts. For seeing it is the fashion of many who would be thought to know much, that every where making ostentation of words and outward termes of Arts, they become a wonder to the ignorant, but a derision to those that are Masters of those Arts: we hope that our Labours shall have a contrarie successe, which is, that they may arrest the judgment of every one who is best vers'd in every particular Art; and be undervalued by the rest . As for those Arts which may seeme to bee of inferior ranke and order, if any man thinke wee attribute too much unto them; Let him looke about him and hee shall see that there bee many of speciall note and great account in their owne Countrie, who when they come to the chiefe City or feat of the Estate, are but of mean ranke and scarcely regarded: so it is no marvaile if these sleighter Arts, placed by the Principall and supreme Sciences, seeme pettie things; yet to those that have chosen to spend their labours and studies in them, they seeme great and excellent matters. And thus much of the Organ of Speech. -- Francis Bacon, The Advancement and Proficience of Learning, p 257-71, Book VI, 1640.


Sciences current work in Cryptography? A Vast difference then what is reveal in the Shakespearean language? Maybe, it is here, where I see the questions of Susskind's thought experiment about the elephant in two places?

We've learnt in the natural sciences that the key to understanding can often be found if we lift certain dividing lines in our minds. Newton showed that the apple falls to the ground according to the same laws that govern the Moon's orbit of the Earth. And with this he made the old differentiation between earthly and heavenly phenomena obsolete. Darwin showed that there is no dividing line between man and animal. And Einstein lifted the line dividing space and time. But in our heads, we still draw a dividing line between "reality" and "knowledge about reality", in other words between reality and information. And you cannot draw this line. There is no recipe, no process for distinguishing between reality and information. All this thinking and talking about reality is about information, which is why one should not make a distinction in the formulation of laws of nature. Quantum theory, correctly interpreted, is information theory.


So we find the methods to determine the beginning(Tabula Rusa) and what had always existed in a ideological discourse about which was before "form?"

Innatism is a philosophical doctrine introduced by Plato in the socratic dialogue Meno which holds that the mind is born with ideas/knowledge, and that therefore the mind is not a tabula rasa at birth. It asserts therefore that not all knowledge is obtained from experience and the senses. Innatism is the opposite of empiricism.

Plato claimed that humans are born with ideas/forms in the mind that are in a dormant state. He claimed that we have acquired these ideas prior to our birth when we existed as souls in the world of Forms. To access these, humans need to be reminded of them through proper education and experience.


So shall one then debate about what existed in the beginning of this universe, if we are presented with the thought that we are already born with knowledge and ideas? That we should start from such a blank slate? So then for you, nothing existed before? Or has something philosophically and profoundly, always existed?

This means you can never discard what you set in motion, only that what you started has consequences, and moves into the next life? So we try and do it right in this one. We accept the burden/choice for growth, and learn.

But this is a personal choice. We do not in face of "what lies in the dormant state" disregard empiricism. You see Plato and Aristotle together, don't you?

So we come to what is of value after we have learn about Cerenkov radiation and what did not exist before, now exists? Time travel? How is this possible in the scenario of LHC? Have we accepted faster then light entities in our assessment of what goes beyond the speed of light? Then I have to show how this is so?

Result of Effective Changes in the Cosmos

"There comes a time when the mind takes a higher plane of knowledge but can never prove how it got there. All great discoveries have involved such a leap. The important thing is not to stop questioning." Albert Einstein (1879- 1955)




But the presence of an event horizon implies a finite Hawking temperature and the conditions for defining the S Matrix cannot be fulfilled. This lack of an S Matrix is a formal mathematical problem not only in string theory but also in particle theories.

One recent attempt to address this problem invokes quantum geometry and a varying speed of light. This remains, as they say, an active area of research. But most experts doubt that anything so radical is required.


What processes would allow you to see "faster then light entities" being shown as examples of that "cross over point?" That's part of the fun isn't it when you realize what some experiments are actually checking for? :)



So yes of course, you might think about "Cerenkov radiation" and from this, what is happening in today's world, that allows us lay people, never having seen or understood, but may now do so?

SNO
The Sudbury Neutrino Observatory is a collaborative effort among physicists from Canada, the U.K., and the U.S. Using 1,000 tons of so-called heavy water and almost 10,000 photon detectors, they measure the flux, energy, and direction of solar neutrinos, which originate in the sun. SNO, located 6,800 feet underground in an active Ontario nickel mine, can also detect the other two types of neutrinos, muon neutrinos and tau neutrinos. In 2001, just two years after the observatory opened, physicists at SNO solved the 30-year-old mystery of the "missing solar neutrinos." They found that the answer lies not with the sun—where many physicists had suspected that solar neutrinos undergo changes—but with the journey they take from the core of the sun to the Earth.


In the previous article I mention the "cross over point in LHC" and from this, the idea was born in mind, how the universe and the effectives rates of expansion could take place?



While it is a long shot, I thought since of layman status, what could it hurt but to speculate and see what thoughts further arise from this. Like any model perspective adopted, allows new thinking to emerge, where previously, none existed for me. So one tends to try and go with the flow and see where it ends up. At least that's what I do and now, others do too?


Blackhole Production in the Cosmos


Increase, in high energy collisions taking place, allows speed up of inflation?



So here is the jest of what allowed me to say that the effective rates of exchange in the cosmos had to have the physics related to show the reasons why the effective speed up of inflation has been detected.


Adapted from Dienes et al., Nuclear Physics B
Some theorists envision the universe as multidimensional space-time embedding a membranous entity, called a brane, also of multiple dimensions. Diagram depicts familiar 3-dimensional space (time not shown) as a vertical line. At every point along line, one extra dimension curls around with a radius (r) of no more that about 10–19 meter. Perpendicular to every point of the brane extends the bulk, another extra dimension.


Also I will give the idea of "photo/graviton association" and how "graviton in a can" allows perspective about the "effective field variations" that "may be" predicted in the vacuum as it produces new physics to emerge on the other side? Quite a mouthful I know.


The graviton is the quantum force carrier of gravity. In conventional quantum field theory, graviton processes with loops do not make sense because of incurable divergencies.


The idea then here is to understand the graviton production in particle collisions here produce some interesting "phenomena" as we see faster then light entities move beyond the confines of that "graviton in a can." So you get the jest then, that even if the boundary conditions are experimentally being tested here, the production of gravitons is very high.

So what allows faster then light entities to move beyond these confines if you did not understand the connection to the "perfect fluid" and the anomalistic nature this perfect fluid has for allowing such traversing beyond the standard model?

That's not all. The fact that space-time itself is accelerating - that is, the expansion of the universe is speeding up - also creates a horizon. Just as we could learn that an elephant lurked inside a black hole by decoding the Hawking radiation, perhaps we might learn what's beyond our cosmic horizon by decoding its emissions. How? According to Susskind, the cosmic microwave background that surrounds us might be even more important than we think. Cosmologists study this radiation because its variations tell us about the infant moments of time, but Susskind speculates that it could be a kind of Hawking radiation coming from our universe's edge. If that's the case, it might tell us something about the elephants on the other side of the universe.

Three Ring Circus: Dark Energy

"Observations always involve theory."Edwin Hubble


Hopefully some day, I will be accepted as a student of this universe, and it's intrigue?



Sometimes it is necessary to understand that having come to different consclusion about the geometry of this universe that underneath the complexity of these equations a schematic drawing of reality is unfolding? I think this is where Einstein's success came from? So assume from this point a supersymmetrical view of the universe?

You can check out Wayne Hu's site for further info on computer simulation below


A simulation of large-scale structure
formation
As the Universe expands, galaxies become more and more distant from each other. For an observer, such as ourselves, it appears that all other galaxies fly away from us. The further the galaxy, the faster it appears to recede. This recession affects the light emitted by the distant galaxies, stretching the wavelengths of emitted photons due to the Doppler redshift effect. The distance between galaxies is proportionalto the measure of this effect 1+z, where z is what astronomers call redshift. The redshift can be measured for each object if its spectrum is measured.


All three geometrical positions demonstrated below each held the cosmologists to views of our universe. But we now know that Einstein may have been right. What allows us to think this way?

Sorry about the quality of artistic rendition. But you get the jest right?

Why is the universe speeding up, and what does this mean geometrically? There has to be some physics going on that would explain this? What may this be?

Current evidence shows that neutrinos do oscillate, which indicates that neutrinos do have mass. The Los Alamos data revealed a muon anti-neutrino cross over to an electron neutrino. This type of oscillation is difficult to explain using only the three known types of neutrinos. Therefore, there might be a fourth neutrino, which is currently being called a "sterile" neutrino, which interacts more weakly than the other three neutrinos.


Of course this information is based on 2003 data but the jest of the idea here is that in order to go to a "fast forward" the conditions had to exist previously that did not included "sterile neutrinos" and were a result of this "cross over."

If we look back to the measures of supernova Ia measure and find that in that time measure there were differences in the inflationary aspect of that universe, then, the universe today would have allowed us to consider the universe quite capable of changing it's speed of inflation.

While indeed we had held to inverse square law in our assumptions, what shall we do now? As you know, spending a couple of years on my own, I am learning, and yes, it shows sometimes. The "idea back then" presented by Savas Dimopoulos of Stanford University. "This gives us a totally new perspective for addressing theoretical and experimental problems," is what was understood in any theoretical development by scientists then and today?

Inverse Fourth Power Law


Savas Dimopoulos of Stanford University
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.


Also, I wouldn't one to think that the experimental process had been defunct what we are doing with Cosmic ray collision processes, to not include it with what the LHC is doing as well. Not only have we created the conditions for it in LHC we recognize as a natural process.

While we know of the components of our universe distributed we understand that their is a part of this whole thing that is casing some questions about what we had thought held to the big bomb's inverse square law rules.

What is causing the Speed increase?

While indeed the layman here speculates, it made more sense if we can now explain what is going on. It has been a long journey in terms of comprehension development but I must say it has been rewarding.



So while indeed I show cosmos particle showers here, it is to point out something that helps to fuel the idea behind the speeding up and slowing down of the universe? Cross over production demonstrate in LHC serves also to speak to the fluctuations in "differing speeds of inflation" in our cosmos?

The "crossover" is a point in the collision process of LHC. So by creating these conditions in the LHC, we have effectively recognized where the "new physics" will emerged from. Also, it presents the opportunity for the "first time here" to address what the effects of the LHC will do for us in terms of what has been presented in terms of the dark energy announced below.



So as close as we came to discerning the mass of the neutrino, what have we now come to know? That their could be "a form" of dark matter? The "point here" was to look for the crossover that was taking place and presenting the opportunities for "new physics" to emerge.

The Los Alamos data revealed a muon anti-neutrino cross over to an electron neutrino. This type of oscillation is difficult to explain using only the three known types of neutrinos.


I have some "thought bubbles" percolating to the surface awareness of my mind(a philosopher?), so we will have to see what strange brew materializes. This is a post in developmental mode.

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. Investigators used Hubble to find that dark energy was already boosting the expansion rate of the universe as long as nine billion years ago. This picture of dark energy is consistent with Albert Einstein's prediction of nearly a century ago that a repulsive form of gravity emanates from empty space. Data from Hubble provides supporting evidence to help astrophysicists to understand the nature of dark energy. This will allow them to begin ruling out some competing explanations that predict that the strength of dark energy changes over time.



The title itself of this blog post is not to make fun of what is happening in cosmology right now with the new announcement today. It is about "forcing the mind" to look at "Friedman's equation" in each of the rings. Now the thought is the "whole show" is the Einstein cosmsological constant circus and entertainment, that is happening simultaneously.

Yet it is the idea of the "oscillating nature" behind the geometrical principals that is what I am speculating about.

But thanks to good professor below there is an more in depth explanation shared.



Maybe with the development of the vision, "beyond the spacetime" we had come to know and love, we have now come to a unique point in time? That we understand the greater "depth of the universe" is now open for questions about it's inherent nature?

What is Dark Matter/Energy?

When Chaos Goes Quantum?

All events shown here (except KEK test detector) were generated by Monte-Carlo simulation program, written by Clark. The visualizing software which produced the detector images was written by Tomasz.


While the sun was easily recognizable building "monte carlo" patterns in computer technology developed from SNO work made such views easily discernible?

Imagine putting all that information through a single point? That "point" is important in terms of the energy perspective. It reveals something very interesting about our universe.

If such experiments as listed here are to be considered in the "forward perspective" then what do you think we have gained in our understanding of supersymmetry? Yes indeed, the undertanding is amazing with the reading of what is given to us below in the Interaction.org links.

The complexity of the information seems well, like, "ligo information" being transcribed into a working image of the cosmos? Complexity of all that information/energy is being processed through the LHC experiment. Consider it's energy values, and all that is being produced as "particle constituents" and yes, there is more.

Cosmic particle collision understanding in this correlation of experiment at LHC, we learn much about the universe.

Quantum physics has revealed a stunning truth about “nothing”: even the emptiest vacuum is filled with elementary particles, continually created and destroyed. Particles appear and disappear, flying apart and coming together, in an intricate quantum dance. This far-reaching consequence of quantum mechanics has withstood the most rigorous experimental scrutiny. In fact, these continual fluctuations are at the heart of our quantum understanding of nature.

The dance of quantum particles has special significance today because it contributes to the dark energy that is driving the universe apart. But there’s a problem: the vacuum has too much energy. A naive theoretical estimate gives an amount about 10120 times too large to fit cosmological observations. The only known way to reduce the energy is to cancel contributions of different particle species against each other, possibly with a new symmetry called supersymmetry. With supersymmetry the result is 1060 times better—a huge improvement, but not enough. Even with supersymmetry, what accounts for the other 60 orders of magnitude is still a mystery.

Physics theory predicts that one of the most important particles in the quantum vacuum is the Higgs particle. The Higgs pervades the vacuum, slowing the motion of particles, giving them mass, and preventing atoms from disintegrating. Since it fills the vacuum, the Higgs itself contributes to the embarrassing factor of 10120.

The next accelerators are opening a window on the pivotal role of symmetry in fundamental physics. New discoveries will teach us about the role of the Higgs particle and supersymmetry in defining the vacuum. Such discoveries are key to understanding what tames the quantum vacuum, a topic that is fundamental to any real understanding of the mysterious dark energy that determines the destiny of our cosmos.


It took me a long time to get to the very point made in terms of the supersymmetrical valuation by understanding what existed "before" was transform from to being by presented another possibily on the other side.

"In fact, these continual fluctuations are at the heart of our quantum understanding of nature."

The only known way to reduce the energy is to cancel contributions of different particle species against each other, possibly with a new symmetry called supersymmetry.


It had to be taken down to a reductionistic point of view in order for this to make any sense. You needed experiments in which this was made possible. Without them, how could we be "lead by science?"

Conclusions


Particle physics is in the midst of a great revolution. Modern data and ideas have challenged long-held beliefs about matter, energy, space and time. Observations have confirmed that 95 percent of the universe is made of dark energy and dark matter unlike any we have seen or touched in our most advanced experiments. Theorists have found a way to reconcile gravity with quantum physics, but at the price of postulating extra dimensions beyond the familiar four dimensions of space and time. As the magnitude of the current revolution becomes apparent, the science of particle physics has a clear path forward. The new data and ideas have not only challenged the old ways of thinking, they have also pointed to the steps required to make progress. Many advances are within reach of our current program; others are close at hand. We are extraordinarily fortunate to live in a time when the great questions are yielding a whole new level of understanding. We should seize the moment and embrace the challenges.


A new LHC experiment is born, is an effect from what existed before? What come after.

Yes, the idea is that universe was not born from colliding particles, but from the supersymetical valuation that existed in the universe in the very beginning. You had to know, how to get there. That such events are still feasible, and are being produced cosmologically as we see evidenced in the "fast forward" experiment.

Discovering the Quantum Universe

Superstrings: A computer's graphical representation of multi-dimensional spacetime


-----------------------------------------------------

Right now is a time of radical change in particle physics. Recent experimental evidence demands a revolutionary new vision of the universe. Discoveries are at hand that will stretch the imagination with new forms of matter, new forces of nature, new dimensions of space and time. Breakthroughs will come from the next generation of particle accelerators — the Large Hadron Collider, now under construction in Europe, and the proposed International Linear Collider. Experiments at these accelerators will revolutionize your concept of the universe.

Finding a heavenly key to climate change

Researchers at the European Organization for Nuclear Research (Cern) in Geneva are looking at how radiation from outer space could be affecting our environment.

A new cutting:edge experiment aims to discover how exactly cosmic rays and the Sun may influence the formation of low:level clouds, and possibly climate change.

More than two centuries ago, the British Astronomer Royal William Herschel noted a correlation between sunspots ? an indicator of solar activity : and the price of wheat in England. He suggested that when there were few sunspots, prices rose.

However, up until recently, there was little to back up this hypothesis. Today, inside an unassuming ? some would say decrepit:looking ? building at Cern, the Cloud (Cosmics Leaving OUtdoor Droplets) experiment might help explain how the Sun affects the climate.

NASA Schedules Dark Energy Discovery Media Teleconference

NASA will host a media teleconference with Hubble Space Telescope astronomers at 1 p.m. EST Thursday, Nov. 16, to announce the discovery that dark energy has been an ever-present constituent of space for most of the universe's history.

Graviton in a Can?

After you consume "graviton in a can," you might never be the same? Brane thinking may then dominate your every view of the world. Then, it will all make sense?

Imagine while we peer deeper into the subject of the "perfect fluid/soup" we find that certain aspects of the reductionist work done, has indeed lead us to speculate on how the "new physics" formed through the research and understanding currently being worked in the LHC?

Is there some architectural design to the "Degree's of Freedom?" Why anything more then the spacetime we have come to recognize, which placed new parameters on our thinking? Moved it from the recogition of Maxwellian and Gaussian coordinates to Riemann geometries in the theory of General Relativity, to become known, as the Theory of gravity. Why "anything" more then that?


A picture of flux lines in QED (left) and QCD (right).
Although it didn't properly describe strong interactions, in studying string theory physicists stumbled upon an amazing mathematical structure. String theory has turned out to be far richer than people originally anticipated. For example, people found that a certain vibrational state of the string has zero mass and spin 2. According to Einstein's theory of gravity, the gravitational force is mediated by a particle with zero mass and spin 2. So string theory is, among many other things, a theory of gravity!


I mean how are such abstract notions in the mathematics supposed to make sense, if we can not see the logic of these formulations working in some kind of reality frame of reference?


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


So we have these diagrams and thought processes developed from individuals like Jacob D. Bekenstein to help us visualize what is taking place. Gives us key indicators of the valuation needed, in order to determine what maths are going to be used? In this case the subject of Conformal Filed Theory makes itself known, for the thought process to hone in on what is going to be spoken too?

Holography encodes the information in a region of space onto a surface one dimension lower. It sees to be the property of gravity, as is shown by the fact that the area of th event horizon measures the number of internal states of a blackhole, holography would be a one-to-one correspondence between states in our four dimensional world and states in higher dimensions. From a positivist viewpoint, one cannot distinguish which description is more fundamental.Pg 198, The Universe in Nutshell, by Stephen Hawking


So we are given the label in which to speak about the holographical ntions of what is being talked about in the case of the blackhole's horizon.


Campbell's Soup Can by Andy Warhol Exhibited in New York (USA), Leo Castelli Gallery


While it is difficult of such images to be found displayed in the bloggery here to show what Dr. Gary Horowitz is saying you get the jest when you go right to the image of the tomato soup can.

Spacetime in String Theory-Dr. Gary Horowitz, UCSB-Apr 20, 2005

This year marks the hundredth anniversary of Einstein's "miraculous year", 1905, when he formulated special relativity, and explained the origin of the black body spectrum and Brownian motion. In honor of this occasion, I will describe the modern view of spacetime. After reviewing the properties of spacetime in general relativity, I will provide an overview of the nature of spacetime emerging from string theory. This is radically different from relativity. At a perturbative level, the spacetime metric appears as ``coupling constants" in a two-dimensional quantum field theory. Nonperturbatively (with certain boundary conditions), spacetime is not fundamental but must be reconstructed from a holographic, dual theory. I will conclude with some recent ideas about the big bang arising from string theory.


Imagine containing everything we know in this can. Yet,we find that the "soup image" has somehow been translated to other factors and values that seem beyond what we know is real. Is real within the confines and boundaries, and is not evidence of the "infinities" that arise from such non containment?

So, what of the "dilation field" that accumulates, as we speak to what the photon is in the measure of Glast. High energy photon determinations that may also be the valuation of the graviton in expression, as the photon travels through these fields?

Such unification is important once we move into the bulk perspective and what we see of the 2d image of the brane, as a value, and discernation of the label of the soup can?


The ALICE TPC in its clean room, where it is undergoing commissioning of all its sectors.

One of the first cosmic-ray events recorded and reconstructed in two sectors of the TPC.
The tests use the ALICE cosmic muon trigger detector ACORDE, as well as a specially designed UV laser system, to produce tracks in the detector. Preliminary analysis of the cosmic-ray events and the laser-induced tracks indicate that the drift velocity and diffusion of electrons liberated by traversing charged particles, as well as the spatial resolution, are very close to the design values.


So here we are then, having graduated in perspective about what is real, as one may ask the sociological aspect of this whole adventure?



If such missing energy is, "not accounted for" then what happens to the graviton as it is produced and causes energy to travel with them?

For example, people found that a certain vibrational state of the string has zero mass and spin 2. According to Einstein's theory of gravity, the gravitational force is mediated by a particle with zero mass and spin 2. So string theory is, among many other things, a theory of gravity!

Gravity and Electromagnetism?

"Yet I exist in the hope that these memoirs, in some manner, I know not how, may find their way to the minds of humanity in Some Dimensionality, and may stir up a race of rebels who shall refuse to be confined to limited Dimensionality." from Flatland, by E. A. Abbott




Oskar Klein and Theodor Franz Eduard Kaluza

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?

Then, to have Gravity and Light United?

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


It seems then that the very statement of "Unification," the "Theory of everything," does not seem so far fetched as we look at the implications of what comes after. What comes from the knowledge, extended.



I was starting to loose hope here in the efforts of blogging as well, and was thinking that the time had come to a end. But "these questions" help to fuel the understanding that I had gained by giving time to "what work" has been put out there by scientists?



To think scientists would close up shop to their elite view, would seem disastrous to me, because of the leading perspective of what the physics means along side of that math.

We need to know what is "experimentally going" on so that we can also judge what theoretical models are doing for us as we extend this knowledge gained.

I gave a few views in environmental sciences in terms of the cosmic relation as well as what Gr was being introduced using time clocks and such, for views of the topographical understanding of earth from a fluidness point of view.

Now join the "cloud cover" along side of particle collisions sources, and have we learn anything that we didn't know before, or has this push new light onto what we now see of earth, as it's placed in the cosmological frontier?

Lisa Randall on Xtra Dimensions

In physics, Randall-Sundrum models imagine that the real world is a higher-dimensional Universe described by warped geometry. More concretely, our Universe is a five-dimensional anti de Sitter space and the elementary particles except for the graviton are localized on a (3 + 1)-dimensional brane or branes.

The models were proposed in 1999 by Lisa Randall and Raman Sundrum while studying technicolor models.



With the online chat yesterday I'll have to look in on Sabine Hossenfelder and Stefan's of Backreaction blog entry in this regard to look at it more in depth.

So you intuitively believe higher dimensions really exist?

I don't see why they shouldn't. In the history of physics, every time we've looked beyond the scales and energies we were familiar with, we've found things that we wouldn't have thought were there. You look inside the atom and eventually you discover quarks. Who would have thought that? It's hubris to think that the way we see things is everything there is.

If there are more than three dimensions out there, how does that change our picture of the universe?


The very ideas are of extra dimensions are very progressive, and are not without some history. Some people will label anything as crackpot, without understanding the history of these discussions."




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.
