Cerebral hemisphere

Stroke of insight:Jill Bolte Taylor

So who are we? We are the life force power of the universe, with manual dexterity and two cognitive minds. And we have the power to choose, moment by moment, who and how we want to be in the world. Right here right now, I can step into the consciousness of my right hemisphere where we are -- I am -- the life force power of the universe, and the life force power of the 50 trillion beautiful molecular geniuses that make up my form. At one with all that is. Or I can choose to step into the consciousness of my left hemisphere. where I become a single individual, a solid, separate from the flow, separate from you. I am Dr. Jill Bolte Taylor, intellectual, neuroanatomist. These are the "we" inside of me.

Which would you choose? Which do you choose? And when? I believe that the more time we spend choosing to run the deep inner peace circuitry of our right hemispheres, the more peace we will project into the world and the more peaceful our planet will be. And I thought that was an idea worth spreading.



So here's the thing. I see the body as a tool for our spirit to manifest, and if we assign the expression of this spirit through the delegations of the brain's hemisphere, then what does this mean about the reality of the idea of position and momentum in our experiencing, if we had thought that such division would have relegated the experience to aspects of the right and left hemisphere?

The link offered by Phil, put this question in my mind, as I am trying to see the place my fabrications of mind as the penetrating of experience reside in the hemispheric association, sees, that such mapping can be assign a introspective measure of our realization of the right brain experience Phil offered in this link.

If we were to think of the oscillatory relation of position and momentum as a feature of the reality we reside in, then the very stages that the "I am resides in" is a fixation of the reality itself. While this can be reduce to a mathematical framework, this aspect of the uncertainty, would have then become the mattered states of existence, as we have come to define aspects of that same reality?

The cerebral hemispheres . See: Chapter 2: The Biological Basis of Behavior-Chapter Review


A cerebral hemisphere (hemispherium cerebrale) is defined as one of the two regions of the brain that are delineated by the body's median plane. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter called the cerebral cortex that is supported by an inner layer of white matter. The hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers, and also by other smaller commissures, including the anterior commissure, posterior commissure, and hippocampal commissure. These commissures transfer information between the two hemispheres to coordinate localized functions. The architecture, types of cells, types of neurotransmitters and receptor subtypes are all distributed among the two hemispheres in a markedly asymmetric fashion. However, it must be noted that, while some of these hemispheric distribution differences are consistent across human beings, or even across some species, many observable distribution differences vary from individual to individual within a given species.


Hemisphere lateralization

Broad generalizations are often made in popular psychology about certain function (eg. logic, creativity) being lateralised, that is, located in the right or left side of the brain. These ideas need to be treated carefully because the popular lateralizations are often distributed across both sides.[1] However, there is some division of mental processing. Researchers have been investigating to what extent areas of the brain are specialized for certain functions. If a specific region of the brain is injured or destroyed, their functions can sometimes be recovered by neighbouring brain regions — even opposite hemispheres. This depends more on the age and the damage occurred than anything else.



The best evidence of lateralization for one specific ability is language. Both of the major areas involved in language skills, Broca's area and Wernicke's area, are in the left hemisphere. Perceptual information from the eyes, ears, and rest of the body is sent to the opposite hemisphere, and motor information sent out to the body also comes from the opposite hemisphere (see also primary sensory areas).


Neuropsychologists (e.g. Roger Sperry, Michael Gazzaniga) have studied split-brain patients to better understand lateralization. Sperry pioneered the use of lateralized tachistoscopes to present visual information to one hemisphere or the other. Scientists have also studied people born without a corpus callosum to determine specialization of brain hemispheres.



The magnocellular pathway of the visual system sends more information to the right hemisphere, while the parvocellular pathway sends more information to the left hemisphere. There are higher levels of the neurotransmitter norepinephrine on the right and higher levels of dopamine on the left. There is more white-matter (longer axons) on right and more grey-matter (cell bodies) on the left.[2]


Linear reasoning functions of language such as grammar and word production are often lateralized to the left hemisphere of the brain. In contrast, holistic reasoning functions of language such as intonation and emphasis are often lateralized to the right hemisphere of the brain. Other integrative functions such as intuitive or heuristic arithmetic, binaural sound localization, emotions, etc. seem to be more bilaterally controlled.[3]

There Be Dragons?

Map of North America from 1566 showing both Terra In Cognita and Mare In Cognito.

Terra incognita (with "incognita" stressed on the second syllable) is the Latin term for "unknown land", used in cartography for regions that have not been mapped or documented. The equivalent on French maps would be terres inconnues (plural form), and some English maps may show Parts Unknown.

Similarly, uncharted or unknown seas would be labeled Mare incognitum, Latin for "unknown sea".

An urban legend claims that cartographers labelled such regions with "Here be dragons". Although cartographers did claim that fantastic beasts (including large serpents) existed in remote corners of the world and depicted such as decoration on their maps, only one known surviving map, the Lenox Globe, in the collection of the New York Public Library [1], actually says "Here be dragons" (using the Latin "hic sunt dracones"). [2] Terra incognita may also refer to the imaginary continent Terra Australis.

During the 19th century terra incognita disappeared from maps, since both the coastlines and the inner parts of the continents had been fully explored.

The phrase is now also used metaphorically by various researchers to describe any unexplored subject or field of research.


I added the "T" for a affirmative statement of the There Be Dragons as a question at hand?

"Here be dragons" is a phrase used by cartographers to denote dangerous or unexplored territories, in imitation of the infrequent medieval practice of putting sea serpents and other mythological creatures in blank areas of maps.

The earliest known use of this phrase was in the Latin form "HC SVNT DRACONES" (i.e. hic sunt dracones) on the Lenox Globe[1] (ca. 1503-07). The term appeared on the east coast of Asia. Earlier maps contain a variety of references to mythical and real creatures, but the Lenox Globe is the earliest one to bear this phrase.


So you got to know that with a statement like, What are the Odds, we might have a truly based reasoning that underscores the importance of presenting the work toward the answer for every statement that causes uncertainty? Not assigning Dragons to unknown territories in terms of new information.

I just want to point out something that has crossed my mind in terms of our past. That in the ole European identification processes names were given to people by the places they had inhibited.

IN the "Bloggery world" such titles it seems ring true, as we say the name of the person and the the title of the blog respectively? How ancient this idea then to bring such a idea to mind here and the histories to the tongue. Try saying this once, twice and as many times as you like, let it roll off your tongue....."Bee and Stefan of Backreaction," or "Clifford of Asymptotia." Yes, it has a ring to it doesn't it:)

Okay, so where am I going with this?

The End of the World Scenarios?

In a paper published in 2000 with the title “Might a Laboratory Experiment Destroy Planet Earth?” Francesco Calogero, a nuclear physicist at the University of Rome and co-winner of the 1995 Nobel Peace Prize for his work with the Pugwash conferences on arms control, deplored a tendency among his colleagues to promulgate a “leave it to the experts” attitude.

“Many, indeed most, of them,” he wrote, “seem to me to be more concerned with the public relations impact of what they, or others, say and write, than in making sure that the facts are presented with complete scientific objectivity.”

What is in the fate of hands who will determine how secretive this world will become Dorigo. That while they advocate their positions on what is shared by our scientists, what can now be brought to bear on the "false thoughts and illusions" that new stories are forever created, while the true sources of knowledge are being clouded?

Do we know better?


Observing a Scientist in Action


Even I can be harsh in my criticisms, and it is my family trait, that when you come from a very large family you tend to care for those less advantaged then others. It's just part of the psychology that we bring to bear, as if a mother taking care of their young, could turn into teachers, "who take are of their students."

In response too "So What Are the Odds?" by Clifford of Asymptotia:)


The Angel and the Demons are here and not here.:) Okay, just a teaspoon of the anti-matter then. No molasses, or anything more profound then?

From "stringevangelism" to "Frank common sense," you've gone to great lengths? But this time, you may have gone to far with these Draconian measures. :)

What next!

The mystic in science is always the infancy of something much more profound? So now being so much more analytical? So easy to denounce our pre-understanding of the larger possibilities, and pass it off to the experts. Then we have all our answers set in stone. Yes!

It is always safer to scoff at what we now determined as safe, but then, who of us hasn't realized that with more knowledge we understood something more? With the reports I had read to update I realized there were a lot of scientists who just did not know what was being talked about, while at Cern, they were quick to dispel what proposals were set forth with the uncertainties. These were respectable attempts at informing the public. There were reports on strangelets that were answered and these were taken seriously.

Least we forget how unsettling the "God particle was" while the Fly's eye was in it's infancy? You see, this is the way of it, and this is the way that those who condemn, light the fires of opposition to what should or should not be revealed to the public.

It is our nature to call this thing a Geon possibly? It's clue to our saying goodbye to men who dream up the nature of things. Should we forget how those who denounced the avenues of string theory were quick to spell out where the genus figures left off, are now much further then some of our good scientists previously understood?

Storms in teacup I, II III, etc.... for sure.:) You were much nicer to the child on the bus.


How wise and prudent our words when there are young ears around to hear,and I have often be scolded by my wife for forgetting about the children. The circumstance in which I am working. So it is not hard to see the reverberations of my not being careful in what I've seen of the children of late whose language has become the reiteration of the circumstance in which they are raised.

So can I say that the young in mind are adults whose ears are listening as well, in the matters of their age, are the students of the process and are listening as well?

Harry Campbell Source from article above.

Beware of the symbolism then used by Dennis Overbye to further this "scoffing at of the ridiculous." These too have a lasting impression. Least we destroy the characters of our heros? See Sir Isaac Newton again for comparisons of what ill fate would be assigned to the ones who reached for the light ,and saw all it's possibilities?

The Devil is In the Details?

So yes there are the creative writers who embellish the situation that help create this hysteria of the uncertainty. Who also bring forth such lovely stories of the fictional that we can somehow relate these events in our time as above?



  • Angels and Demons






  • The Devil, is in the details of a Mirror World?


    While the "true cast" is here? :)

    Mirror world or Alice in Wonderland, we have a unique way of adding the incredibility to the credible?

    Configuration Space

    Lee Smolin:
    For Newton the universe lived in an infinite and featureless space.There was no boundary, ad no possibility of conceiving anything outside of it. This was no problem for God, as he was everywhere. For Newton, space was the "sensorium" of God-the medium of his presence in and attachment to the world. The infinity of space was then a necessary reflection of the infinite capacity of God.The Life of the Cosmos By Lee Smolin Oxford University Press; New York, N.Y.: 1997, Page 91


    Should one think we should dismiss the historical context by assigning comments to the characters of that past? See the "Character of our Heros" for an update on my thinking.I think it is cheap what we can do sometimes, while this history has never been completely told? What is it I mean?

    It is a way in which I look at life and the way in which it came together for me. If such a source is recognized that emanates the very constructive phases of all life, then, what was the underlying substance of this creation if it could not be expressive?

    David Joseph Bohm (b. December 20, 1917, Wilkes-Barre, Pennsylvania - d. October 27, 1992, London) was an American-born quantum physicist who made significant contributions in the fields of theoretical physics, philosophy and neuropsychology, and to the Manhattan Project.

    If man thinks of the totality as constituted of independent fragments, then that is how his mind will tend to operate, but if he can include everything coherently and harmoniously in an overall whole that is undivided, unbroken, and without a border then his mind will tend to move in a similar way, and from this will flow an orderly action within the whole. (David Bohm, Wholeness and the Implicate Order, 1980)


    If a shaft of light entering a prism is sufficiently narrow, a spectrum results.

    In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms are typically made out of glass, but can be made from any material that is transparent to the wavelengths for which they are designed.

    A prism can be used to break light up into its constituent spectral colors (the colors of the rainbow). Prisms can also be used to reflect light, or to split light into components with different polarizations.


    Dispersion

    In optics, dispersion is the phenomenon that the phase velocity of a wave depends on its frequency.[1] The most familiar example of dispersion is probably a rainbow, in which dispersion causes the spatial separation of a white light into components of different wavelengths (different colors). However, dispersion also has an impact in many other circumstances: for example, it causes pulses to spread in optical fibers, degrading signals over long distances; also, a cancellation between dispersion and nonlinear effects leads to soliton waves. Dispersion is most often described for light waves, but it may occur for any kind of wave that interacts with a medium or passes through an inhomogeneous geometry (e.g. a waveguide), such as sound waves. Dispersion is sometimes called chromatic dispersion to emphasize its wavelength-dependent nature.


    The Value of Time

    Lee Smolin:
    I suspect this reflects the expectation many people have that time is not fundamental, but rather emerges only at a semiclassical approximation in quantum cosmology. If you believe this then you believe that the fundamental quantities a quantum cosmology should compute are timeless. This in turn reflects a very old and ultimately religious prejudice that deeper truths are timeless. This has been traced by scholars to the theology of Newton and contemporaries who saw space as “the sensorium” of an eternal and all seeing god. Perhaps the BB paradox is telling us it is time to give up the search for timeless probability distributions, and recognize that since Darwin the deep truths about nature cannot be divorced from time.

    The alternative is to disbelieve the arguments that time is emergent-which were never very convincing- and instead formulate quantum cosmology in such a way that time is always real. I would suggest that the Boltzman Brain’s paradox is the reducto ad absurdum of the notion that time is emergent and that rather than play with little fixes to it we should try to take seriously the opposite idea: that time is real.


    Configuration space to me would mean a relationship to the way tungsten bar of lead would have through it's coordinated dimensions as shown below pinpointed the results according to the space that this measure occupies? Now this could mean some totally different to th way I am seeing it, yet knowing full well the scope of the spectrum , the evidence to the contrary of that one wave, would have been the refractive differences shown not only in that Prism, but the elemental consideration as signature by the elements presence.

    Calorimeters measure the collective behavior of particles traveling along approximately the same path, and are thus naturally suited for the measurement of jets-Dorigo Tommaso
    See Previous post on the Calorimeters

    When pushing back perspective it is of course used in concert with how we shall see the events unfold in the cosmos. Any measurement used in the LHC at this time is tied to that same understanding of events as they unfold for us, not only in context of this "whole universe," but on any subsequent events that happen within context of parts of that same universe.

    Bohmian Mechanics

    Bohmian mechanics, which is also called the de Broglie-Bohm theory, the pilot-wave model, and the causal interpretation of quantum mechanics, is a version of quantum theory discovered by Louis de Broglie in 1927 and rediscovered by David Bohm in 1952. It is the simplest example of what is often called a hidden variables interpretation of quantum mechanics. In Bohmian mechanics a system of particles is described in part by its wave function, evolving, as usual, according to Schrödinger's equation. However, the wave function provides only a partial description of the system. This description is completed by the specification of the actual positions of the particles. The latter evolve according to the 'guiding equation,' which expresses the velocities of the particles in terms of the wave function. Thus, in Bohmian mechanics the configuration of a system of particles evolves via a deterministic motion choreographed by the wave function. In particular, when a particle is sent into a two-slit apparatus, the slit through which it passes and where it arrives on the photographic plate are completely determined by its initial position and wave function.

    Bohmian mechanics inherits and makes explicit the nonlocality implicit in the notion, common to just about all formulations and interpretations of quantum theory, of a wave function on the configuration space of a many-particle system. It accounts for all of the phenomena governed by nonrelativistic quantum mechanics, from spectral lines and scattering theory to superconductivity, the quantum Hall effect and quantum computing. In particular, the usual measurement postulates of quantum theory, including collapse of the wave function and probabilities given by the absolute square of probability amplitudes, emerge from an analysis of the two equations of motion - Schrödinger's equation and the guiding equation - without the traditional invocation of a special, and somewhat obscure, status for observation.

    Calorimetric Views

    BEHOLDING beauty with the eye of the mind, he will be enabled to bring forth, not images of beauty, but realities, for he has hold not of an image but of a reality, and bringing forth and nourishing true virtue to become the friend of God and be immortal, if mortal man may. Would that be an ignoble life? PLATO



    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. CsI(Tl) bars, arranged in a segmented manner, give both longitudinal and transverse information about the energy deposition pattern. Once a gamma ray penetrates through the anticoincidence shield, the silicon-strip tracker and lead converter planes, it then passes into the cesium-iodide calorimeters. This causes a scintillation reaction in the cesium-iodide, and the resultant light flash is photoelectrically converted to a voltage. This voltage is then digitized, recorded and relayed to earth by the spacecraft's onboard computer and telemetry antenna. Cesium-iodide blocks are arranged in two perpendicular directions, to provide additional positional information about the shower.


    The complexity and sum over histories leaves an indelible pathway for all energy Disposition patterns(photons in the Electromagnetic Calorimeters), as well as, an adventure "within the confines of the Hadronic Calorimeters views."

    In a sense when referenced to a "configuration space," then what design of the calorimeter that we would measure the earliest signs o the universe in expression as the "supposed productions of the cosmos." That we could say, we have a "new view in the window of that same cosmos?"

    The future

    If new detectors will ever be built to explore a yet higher energy regime than the one about to be probed by LHC, calorimeters will be as necessary as they are today. The following characteristics will be desirable in a design of new generation:

    * self-triggering (the ability of independent portions of the system to identify and measure a signal, interpreting it and sending an accept signal to the data aquisition system)
    * stand-alone tracking (the ability of the calorimeter system to independently determine the direction of crossing particles)
    * an integrated time-of-flight measurement (the capability to separate different particle signals based on the delay between their arrival time and the interaction time)
    * high resolution and granularity (attainable with silicon technology)

    The needs of these fancy features, however, rests on the specific hunt that we will decide to embark on. Which, in turn, critically depends on the discoveries that the Large Hadron Collider will produce!

    The Toposense of Spacetime

    Topo-Greek, from topos, place.

    Basic Examples
    In the early 1960s Grothendieck chose the Greek word topos (which means “place”) to denote a mathematical object that would provide a general framework for his theory of étale cohomology and other variants related to his philosophy of descent. Even
    if you do not know what a topos is, you have surely come across some of them. Here are two examples:
    See: What is a Topos? by Luc Illusie

    Of course I am looking and trying to describe "Topo" in a different way. I do not want to diminish the significance of the mathematical intents. Just the realization of what we are doing with our perceptions, as we send them to extraordinary depth of of creation.



    In 1952, in his book Relativity, in discussing Minkowski's Space World interpretation of his theory of relativity, Einstein writes:

    Since there exist in this four dimensional structure [space-time] no longer any sections which represent "now" objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more natural to think of physical reality as a four dimensional existence, instead of, as hitherto, the evolution of a three dimensional existence. Albert Einstein


    Of course it was necessary to understand the evolution of Euclidean geometries to the non-euclidean, and the history associated with this. The word "Toposense" is one that becomes endearing when you realize that if your were to take to the meaning of "slide of light to heart" you would see the implications of what gravity could mean in the presence of the photon and it's explanatory revolutionary ideas about how it can encourage "Gravities Rainbow" here within context of this blog.

    "On the Effects of External Sensory Input on Time Dilation." A. Einstein, Institute for Advanced Study, Princeton, N.J.

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


    Unfortunately the link to the article below( now shows as Intuitively Excellent) has been removed from Scientific America's data base or has changed, or, I may of copied it wrong in my search. Nevertheless, I do not have the link, but would like to conclude the remark above, in terms of those pointed out for further repercussions of that conclusiveness.

    Einstein scholars disagree, but the pretty girl/hot stove experiment also may have led to another of his pithy remarks, namely: "If we knew what it was we were doing, it would not be called research, would it?" Then again, Einstein was a bit of a wag. Consider his explanation of wireless communication: "The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York, and it meows in Los Angeles. The wireless is the same, only without the cat." This quote reportedly kept Schrödinger awake well past his bedtime.


    Summing over Histories?



    So how does all this come together into a physical theory? It turns out that the proper procedure is to construct every possible diagram allowed by the theory (for a given state of input and output particles and how they're moving) and add up the corresponding complex numbers. The result is essentially the "wave function" for that specific input-output state combination, and by squaring that number you can determine the probability that the given input will result in the given output. Doing that is how theorists at particle accelerators earn their keep.
    See: An Introduction to String Theory by Steuard Jensen

    So you look at the basis of interactions that Feynman produced in his Toy models and having some insight to the elemental consideration of those same interactions, what comes out, if we were to see the world in such a way, that continuity of expression is "the Wave that was generated in the very beginning," could have been reduce to some refractive expression of all life. The Spectrum, Hydrogen, or other wise.

    Do we then know the nature of the source, that we are all derivatives of some coherent plan that manifests toward the "cyclical nature of being?" Some Shakespearean version of, "to E or not to E?"


    Every known particle has an antiparticle; if they encounter one another, they will annihilate with the production of two gamma-rays. The quantum energies of the gamma rays is equal to the sum of the mass energies of the two particles (including their kinetic energies). It is also possible for a photon to give up its quantum energy to the formation of a particle-antiparticle pair in its interaction with matter.


    No longer Reducible and Working from the Horizon?



    How far can our perceptions be pushed? Can consciousness still remain as part of this "ability of creation," that we are still "part and parcel" of it to consider it's full scope?

    So no geometrical idealizations in sight, other then to consider the significance of a place that is far removed from our looking to the cosmos, and while thinking about it, how far it has been reduce to a fuller picture of it's reality?

    Determinism/Indeterminism

    Determinism

    Determinism (also called antiserendipity) is the philosophical proposition that every event, including human cognition and behavior, decision and action, is causally determined by an unbroken chain of prior occurrences.[1] With numerous historical debates, many varieties and philosophical positions on the subject of determinism exist from traditions throughout the world.


    Determinism, quantum mechanics and classical physics

    Some people have argued that in addition to the conditions humans can observe and the rules they can deduce there are hidden factors or hidden variables that determine absolutely in which order electrons reach the screen. They argue that the course of the universe is absolutely determined, but that humans are screened from knowledge of the determinative factors. So, they say, it only appears that things proceed in a merely probabilistically determinative way. Actually, they proceed in an absolutely determinative way. Although matters are still subject to some measure of dispute, quantum mechanics makes statistical predictions that would be violated if some local hidden variables existed. There have been a number of experiments to verify those predictions, and so far they do not appear to be violated although many physicists believe better experiments are needed to conclusively settle the question. (See Bell test experiments.) It is, however, possible to augment quantum mechanics with non-local hidden variables to achieve a deterministic theory that is in agreement with experiment. An example is the Bohm interpretation of quantum mechanics.

    So quantum mechanics is deterministic, provided that one accepts the wave function itself as reality (rather than as probability of classical coordinates). Since we have no practical way of knowing the exact magnitudes, and especially the phases, in a full quantum mechanical description of the causes of an observable event, this turns out to be philosophically similar to the "hidden variable" doctrine.


    Libertarianism (metaphysics)

    Libertarianism is a philosophical position in metaphysics with respect to free will and determinism. It entails the belief that human beings possess free will, that free will is incompatible with determinism, and that determinism is false.

    Although not held by the majority of contemporary philosophers, libertarianism is still widely discussed and avidly defended by several leading philosophers in the field, such as Peter van Inwagen, Robert Kane, Timothy O'Connor and Laura Ekstrom.



    Natural libertarianism

    Naturalistic libertarians believe that the universe contains an indeterminstic element, for instance as demonstrated by quantum mechanics, and that human beings exploit this to achieve freedom of choice. There is no separate, dualistic self in this theory: the self is the total activity of the brain as a system.


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

    Indeterminism

    At one time, it was assumed in the physical sciences that if the behavior observed in a system cannot be predicted, the problem is due to lack of fine-grained information, so that a sufficiently detailed investigation would eventually result in a deterministic theory ("If you knew exactly all the forces acting on the dice, you would be able to predict which number comes up"). However, the advent of quantum mechanics removed the underpinning from that approach, with the claim that (at least according to the Copenhagen interpretation) the most basic constituents of matter behave indeterministically, in accordance with such properties as the uncertainty principle. Quantum indeterminism was controversial on its introduction, with Einstein among the opposition, but gradually gained ground. Experiments confirmed the correctness of quantum mechanics, with a test of the Bell's theorem by Alain Aspect being particularly important because it showed that determinism and locality cannot both be true. Bohmian quantum mechanics remains the main attempt to preserve determinism (albeit at the expense of locality).


    Bohm interpretation

    The Bohm interpretation of quantum mechanics, sometimes called Bohmian mechanics, the ontological interpretation, or the causal interpretation, is an interpretation postulated by David Bohm in 1952 as an extension of Louis de Broglie's pilot-wave theory of 1927 . Consequently it is sometimes called the de Broglie-Bohm theory. Bohm's interpretation is an example of a hidden variables theory. It is hoped that the hidden variables would provide a local deterministic objective description that would resolve or eliminate many of the paradoxes of quantum mechanics, such as Schrödinger's cat, the measurement problem, the collapse of the wavefunction, and similar concerns. However, Bell's inequality complicates this hope, as it demonstrates that there is no local hidden variable theory that is compatible with quantum mechanics. Thus, one is left with choosing between the lesser of two evils: discarding locality, or discarding realism. The Bohmian interpretation opts for keeping realism and accepting nonlocality.


    Nonlocality

    Others see the consequences of EPR and Bell's theorem in a different way. They regard the correct conclusion to be related not so much to quantum theory itself, but only to deterministic interpretations of the same (i.e., to hidden-variable theories such as Bohm's interpretation). According to the people who think this way, what has been shown is that all deterministic theories must be nonlocal. For example, Niels Bohr was a member of this group. This group would claim that retaining orthodox quantum mechanics — with its nondeterministic character — permits one to retain locality, or at least to avoid the EPR type of nonlocality, at the expense of having no way to picture particles as objective elements of reality that occupy definite regions of space at all times. Armed with such a viewpoint, these physicists tend to be less receptive to Bohm's interpretation.


    Seen as isomorphic to many worlds

    Explicitly non-local. Bohm accepts that all the branches of the universal wavefunction exist. Like Everett, Bohm held that the wavefunction is real complex-valued field which never collapses. In addition Bohm postulated that there were particles that move under the influence of a non-local "quantum- potential" derived from the wavefunction (in addition to the classical potentials which are already incorporated into the structure of the wavefunction). The action of the quantum- potential is such that the particles are affected by only one of the branches of the wavefunction. (Bohm derives what is essentially a decoherence argument to show this, see section 7,#I [B]).

    The implicit, unstated assumption made by Bohm is that only the single branch of wavefunction associated with particles can contain self-aware observers, whereas Everett makes no such assumption. Most of Bohm's adherents do not seem to understand (or even be aware of) Everett's criticism, section VI [1], that the hidden- variable particles are not observable since the wavefunction alone is sufficient to account for all observations and hence a model of reality. The hidden variable particles can be discarded, along with the guiding quantum-potential, yielding a theory isomorphic to many-worlds, without affecting any experimental results.

    Incompatible Arrows

    Commerce is of trivial import; love, faith, truth of character, the aspiration of man, these are sacred.Ralph Waldo Emerson


    I just happen to visit Cosmic Variance yesterday after not visiting for some time. The timing seemed appropriate to my questions about our histories, not only from a detailed research perspective, but from a personal one as well in terms of our memories. I do not care who is an atheist or not. Why should I apply a stereotype to another person and dictate the way the conversation can go?:)

    Sean Carroll has a interesting set of four entires about the backwardness of the arrow of time and how it would appear. This is an interesting exercise for me on how perception about the current direction of the universe could have represented "the Egg before the chicken" scenarios.

    Reverse chronologynarrating a story, or parts of one, backwards in time — is a venerable technique in literature, going back at least as far as Virgil’s Aeneid. Much more interesting is a story with incompatible arrows of time: some characters live “backwards” while others experience life normally.


    There are reasons why I find this fascinating and why the topic of Kurt Godel was introduced in that comment section. It is something that caught my eye while researching Kurt Godel. I will try and find this point and put it here for consideration. While considering the version I saw of his authored biographical comment, it made me think of the views people "can have" about the nonsensical. The feelings they can have about the "incompleteness of this life" and the succession of our views on this life as a "metamathematical position." Where is that? Some "OverSoul" perhaps?:)

    It reminded me about the perspective we can have "from the here and now."

    Mind Body problem

    Proud atheists

    Steve Paulson:I know neither of you believes in paranormal experiences like telepathy or clairvoyant dreams or contact with the dead. But hypothetically, suppose even one of these experiences were proven beyond a doubt to be real. Would the materialist position on the mind-brain question collapse in a single stroke?

    PINKER: Yeah.

    GOLDSTEIN: Yeah, if there was no other explanation. We'd need to have such clear evidence. I have to tell you, I've had some uncanny experiences. Once, in fact, I had a very strange experience where I seemed to be getting information from a dead person. I racked my brain trying to figure out how this could be happening. I did come up with an explanation for how I could reason this away. But it was a very powerful experience. If it could truly be demonstrated that there was more to a human being than the physical body, this would have tremendous implications.


    While I had read your link Phil on Goldstein, I am not an atheist(I try and refrain from groupings) in any form, and, like the topics of "Intelligent design" or the Anthropic principle, this has no bearing on how I want to move and think in the world. I am convinced, as Goldstein was, on what is consider "proof of the afterlife" that I do not need to be reminded of what is evidenced to the contrary, until it is proofed conclusively.

    "Death, so called, is but older matter dressed
    In some new form. And in a varied vest,
    From tenement to tenement though tossed,
    The soul is still the same, the figure only lost."
    Poem on Pythagoras, Dryden's Ovid.


    I may share a trait of Plato eh?:)Emerson? Benjamin Franklin?

    From A Defense of an Essay of Dramatic Poesy (1668) by John Dryden

    Imagination in a man, or reasonable creature, is supposed to participate of reason, and when that governs, as it does in the belief of fiction, reason is not destroyed, but misled, or blinded: that can prescribe tot he reason, during the time of the representation, somewhat like a weak belief of what it sees and hears; and reason suffers itself to be so hoodwinked, that it may better enjoy the pleasures of the fiction: but it is never so wholly made a captive as to be drawn headlong into a persuasion of those things which are most remote from probability: 'tis in that case a free-born subject, not a slave; it will contribute willingly its assent, as far as it sees convenient, but will not be forced....Fancy and reason go hand in hand; the first cannot leave the last behind; and though fancy, when it sees the wide gulf, would venture over, as the nimbler; yet it is withheld by reason, which will refuse to take the leap, when the distance over it appears too large

    Kurt Godel

    He turned the lens of mathematics on itself and hit upon his famous "incompleteness theorem" — driving a stake through the heart of formalism By DOUGLAS HOFSTADTER


    Source:ALFRED EISENSTAEDT/TIME LIFE PICTURES-Kurt Godel at the Institute of Advanced Study See: The Time 100-Scientists and Thinkers

    Kurt Gödel (IPA: [kuɹtˈgøːdl]) (April 28, 1906 Brno (Brünn), Austria-Hungary (now Czech Republic) – January 14, 1978 Princeton, New Jersey) was an Austrian American mathematician and philosopher.

    The Time 100-Scientists and Thinkers

    The upshot of all this is that the cherished goal of formalization is revealed as chimerical. All formal systems — at least ones that are powerful enough to be of interest — turn out to be incomplete because they are able to express statements that say of themselves that they are unprovable. And that, in a nutshell, is what is meant when it is said that Gödel in 1931 demonstrated the "incompleteness of mathematics." It's not really math itself that is incomplete, but any formal system that attempts to capture all the truths of mathematics in its finite set of axioms and rules. To you that may not come as a shock, but to mathematicians in the 1930s, it upended their entire world view, and math has never been the same since.

    Gödel's 1931 article did something else: it invented the theory of recursive functions, which today is the basis of a powerful theory of computing. Indeed, at the heart of Gödel's article lies what can be seen as an elaborate computer program for producing M.P. numbers, and this "program" is written in a formalism that strongly resembles the programming language Lisp, which wasn't invented until nearly 30 years later.


    Princeton

    In the late 1940s, Gödel demonstrated the existence of paradoxical solutions to Albert Einstein's field equations in general relativity. These "rotating universes" would allow time travel and caused Einstein to have doubts about his own theory. His solutions are known as the Gödel metric.


    Closed timelike curves

    Because of the homogeneity of the spacetime and the mutual twisting of our family of timelike geodesics, it is more or less inevitable that the Gödel spacetime should have closed timelike curves (CTC's). Indeed, there are CTCs through every event in the Gödel spacetime. This causal anomaly seems to have been secretly regarded as the whole point of the model by Gödel himself, who allegedly spent the last two decades of his life searching for a proof that death could be cheated, and apparently felt that this solution provided the desired proof. This strange conviction came to light decades after his death, when his personal papers were examined by a startled astronomer.[citation needed].

    A more rational interpretation of Gödel's motives is that he was striving to (and arguably succeeded in) proving that Einstein's equations of spacetime are not consistent with what we intuitively understand time to be (i.e. that it passes and the past no longer exists), much as he, conversely, succeeded with his Incompleteness Theorems in showing that intuitive mathematical concepts could not be completely described by formal mathematical systems of proof. See the book A World Without Time (ISBN 0465092942).


    General Relativity

    CTCs have an unnerving habit of appearing in locally unobjectionable exact solutions to the Einstein field equation of general relativity, including some of the most important solutions. These include:

    * the Kerr vacuum (which models a rotating uncharged black hole)
    * the van Stockum dust (which models a cylindrically symmetric configuration of dust),
    * the Gödel lambdadust (which models a dust with a carefully chosen cosmological constant term).
    * J. Richard Gott has proposed a mechanism for creating CTCs using cosmic strings.

    Some of these examples are, like the Tipler cylinder, rather artificial, but the exterior part of the Kerr solution is thought to be in some sense generic, so it is rather unnerving to learn that its interior contains CTCs. Most physicists feel that CTCs in such solutions are artifacts.


    Timelike topological feature

    No closed timelike curve (CTC) on a Lorentzian manifold can be continuously deformed as a CTC to a point, because Lorentzian manifolds are locally causally well-behaved. Every CTC must pass through some topological feature which prevents it from being deformed to a point. A test particle free falling along a closed timelike geodesic transits this feature; in the test particle's frame, the feature propagates toward the test particle. This features resembles a glider in Conway's Game of Life, but in a continuous spatial automaton rather than a (discrete) cellular automaton.


    Continuous spatial automaton

    It is an important open question whether pseudo-photons can be created in an Einstein vacuum space-time, in the same way that a glider gun in Conway's Game of Life fires off a series of gliders. If so, it is argued that pseudo-photons can be created and destroyed only in multiples of two, as a result of energy-momentum conservation.

    Time is Like a River

    How can a speck of a universe be physically identical to the great expanse we view in the heavens above? (Greene, The Elegant Universe, pages 248-249)



    As Alice learned, it's not always clear what's a looking glass, and what's a window to another world. Mirrors and windows are often interchangeable: we look out into the world, and see ourselves reflected back. We look at a reflection, and believe it's showing us a world beyond. We internalize the mirror image and project the one inside. Objects, actions and ideas can become so confused with their reflections that it's impossible to untangle them. What's phantom and what's real? Is there even a relevant difference?


    It is necessary that one see the very action of "reflection and memory" on our behalf as a continuance of the interplay between our environment and ourselves. Where "attention and awareness constantly brings us back to the waking reality around us."

    I needed some geometrical(topological) way for this continuance of motion, while giving examples of what happens in our universe, as it it expressed itself in that moment of creation. That we may say that while so macroscopically large there exists within us in the nature of the microscopic, the very blueprints of this same creation.

    Now, please spare me the nonsense of Intelligent design and the creation principle that all have argued time and time again. I do not take to those aspects of the debate, whilst I fumble amongst my own illusions, to make sense of what can happen in my own experience.

    Yes, Skeptically this is of no value to you as you read this, as it is a measure against the back drops of science. But there is something that must be said about what we are all are capable of.




    "The worst disease afflicting human kind is hardening of the categories." - Artist Bob Miller.


    They had to be some overriding principle that has evaded our attention when it comes to what is possible and what is not. That I shall choose "time is like a river" does not discount that the river shall have it's eddies and pools for consideration that while in the flow of the process of this unfolding of our own "psychological natures" there is a history to each of us that is beyond the measure of this life?


    The Super Hero Versions

    Miracles StudiosThrone Plates
    To activate Thorne plates, the distance between each plate must be less than the width of an atom. The resulting wormhole will be equally small, so getting in and out might be difficult. To widen the portal, some scientists suggest using a laser to inject immense amounts of negative energy. In addition, Thorne believes that radiation effects created by gravitons, or particles of gravity, might fry you as you enter the wormhole. According to string theory, however, this probably won't happen, so it's scant reason to cancel your trip.


    Miracles StudiosGott Loop
    To take you back one year, the string must weigh about half as much as the Milky Way galaxy. You'll need a mighty big spaceship to make that rectangle.

    Many scientists believe the big bang that created the universe left behind cosmic strings - thin, infinitely long filaments of compressed matter. In 1991, Princeton physicist J. Richard Gott discovered that two of these structures, arranged in parallel and moving in opposite directions, would warp space-time to allow travel to the past. He later reworked the idea to involve a single cosmic-string loop. A Gott loop can take you back in time but not forward. The guide to building your own:


    Miracles StudiosGott Shell
    This is a relatively slow method of time travel, and life inside the shell could become tedious.

    In essence, a Gott shell is a huge concentration of mass. The shell's sheer density creates a gravitational field that slows down the clock for anyone enclosed within it. Outside, time rolls along at its familiar pace, but inside, it creeps. Thus the Gott shell is useful for travel into the future only. If you're planning a jaunt to the past using a Gott loop, you might want to bring along a Gott shell for the return trip. What to do, step by step:


    Miracles StudiosVan Stokum Cylinder
    The cylinder must be infinitely long, which could add slightly to its cost.

    Mass and energy act on space-time like a rock thrown into a pond: the bigger the rock, the bigger the ripples. Physicist W. J. van Stockum realized in 1937 that an immense cylinder spinning at near-light speed will stir space-time as though it were molasses, pulling it along as the cylinder turns. Although Van Stockum himself didn't recognize it, anyone orbiting such a cylinder in the direction of the spin will be caught in the current and, from the perspective of a distant observer, exceed the speed of light. The result: Time flows backward. Circle the cylinder in the other direction with just the right trajectory, and this machine can take you into the future as well. How it works:


    Kerr Ring
    The Kerr ring is a one-way ticket. The black hole's gravity is so great that, once you step through it, you won't be able to return.

    When Karl Schwarzschild solved Einstein's equations in 1917, he found that stars can collapse into infinitesimally small points in space - what we now call black holes. Four decades later, physicist Roy Kerr discovered that some stars are saved from total collapse and become rotating rings. Kerr didn't regard these rings as time machines. However, because their intense gravity distorts space-time, and because they permit large objects to enter on one side and exit on the other in one piece, Kerr-type black holes can serve as portals to the past or the future. If finding one with the proper dimensions is too much trouble, you can always build one yourself:

    Just Plain Ole Us

    I have always been fascinated by the Time Travel Scenarios.

    There is a reason for me to go beyond what we know with regards to the avenues of science in terms of Time Travel. That one could have created a version of a superhero's ability to make this journey, and somehow, come out on the other side? Wonderful:)


    Welcome to the mirror world, in which every particle in the known universe could have a counterpart. This cosmos would hold mirror planets, mirror stars, and even mirror life.


    No I do not believe that we can measure what consciousness is able to do in terms of this time travel( unless some artifact could have found it's place amongst the value of carbon dating to have said, hey, "lets take this television and turn it on.") So that we may look into the objects very past. I have some ideas about this that I will try and lay out here that has become part of my belief system. People can make of it what they like.

    The Complexity of Belief

    Crucifixion (Corpus Hypercubus) (1954)-
    Salvador Domingo Felipe Jacinto Dalí i Domènech, 1st Marquis of Púbol (May 11, 1904 – January 23, 1989), was a Spanish surrealist painter born in Figueres, Catalonia, Spain.


    Some try and internalize the basis of reality as having some "point of expression" while they give empathetic meaning to the nature of geometrical forms. That one may of thought of the crystalline nature as an expression of "some other plan", is of interest to me( not that God created this, but that is part of the genetics of our discovery of self), whether we just talk about the "social aspect of our interactions" or some expression of an geometrical construct being the basis of the universe. I like this phrase of Stephen Hawkings as he enters the Wormhole. He writes,"In the future it is proved that the dynamical evolution of generic initial conditions can never produce a naked singularity."

    It is important to keep perspective on where the fire is. Some may understand this if I was to infer the cave for examination. yet having moved the idea here then to a 2D map of a 5D reality would be part of the plan as I write the Mind map and process of merging two historical points over top of one another.



    A tesserack or hypercube is a four dimensional analogue of a cube. See the figure on the left for a 2-D representation of this 4-D object. More information about these can be seen and found. Many people have difficulty believing such can exist which is why such books as Flatland (Abbott, 1884), Sphereland (Burgers, 1983), and Flatterland (Stewart, 2001) were written.


    It would be as if "one looked at the cube just the right way," what they saw of the cube could be turned into the hypercube, and from this, this inference of the multiplicity of probabilities. This again points to what I see of the Pyramid and what enters from "such a location as the pebble" could have housed all possibilities, and yet, any soul would have found itself following an "arrow of time," and if able too, and done in just that same way, bring into the line the ability of continuity to be induced as a flow.
