The Journey For Natural Quasicrystals

"From future structural and kinematical studies of known quasicrystals, such as AlNiCo, these principles may be established providing a new understanding of and new control over the formation and structure of quasicrystals. See: A New Paradigm for the Structure of Quasicrystals 

Read an interesting article by: Natalie Wolchover June 13, 2014 in a Article called, "In a Grain, a Glimpse of the Cosmos."  This article is located in the Quanta Magazine, by the Simons Foundation under the Physics section.



I really enjoyed the search for who supplied the original sample and from where. The journey back to the spot. Since following the subject of quasi-crystals for some time now, this journey was a nice addition to understanding the nature of matter in the early universe. This goes toward foundation, and my understanding of the work to piece together how nature sought to express itself materialistically from  Reflection_symmetry as a representation of that early universe. I might have to be corrected here.

 The concept of aperiodic crystal was coined by Erwin Schrödinger in another context with a somewhat different meaning. In his popular book What is life? in 1944, Schrödinger sought to explain how hereditary information is stored: molecules were deemed too small, amorphous solids were plainly chaotic, so it had to be a kind of crystal; as a periodic structure could not encode information, it had to be aperiodic. DNA was later discovered, and, although not crystalline, it possesses properties predicted by Schrödinger—it is a regular but aperiodic molecule. See Also, with regard to Shrodinger: A New Physics Theory of Life

Sir Roger Penrose's adaptation here of  Penrose tiling is also of some interest to me as well.

Quantum Tunnelling

Quantum tunnelling or tunneling (see spelling differences) refers to the quantum mechanical phenomenon where a particle tunnels through a barrier that it classically could not surmount. This plays an essential role in several physical phenomena, such as the nuclear fusion that occurs in main sequence stars like the Sun.[1] It has important applications to modern devices such as the tunnel diode,[2] quantum computing, and the scanning tunnelling microscope. The effect was predicted in the early 20th century and its acceptance, as a general physical phenomenon, came mid-century.[3]



ABSTRACT Surprisingly robust quantum effects have been observed in warm biological systems. At the same time quantum information technology has moved closer to physical realization. This one day workshop will examine the significance of mesoscopic quantum coherence, tunneling and entanglement in biomolecular membranes, proteins, DNA and cytoskeleton, with particular attention to recently discovered megahertz ballistic conductance in microtubules. Potential utilization of biomolecular quantum information in regulation of cellular activities will be addressed, along with implications for disease and therapy as well as the future development of quantum computation and artificial intelligence.Google Workshop on Quantum Biology, Welcome and Introduction, Presented by Hartmut Neven

A Universe on the Other Side

 "I think people thought that the universe was smaller, yet discoveries in the last century have found there are black holes everywhere, billions of black holes in our universe and each may produce a universe on the other side, like an infinite tree," he said. - See more at: New Hit Film ‘Gravity’ Speaks to Our Endless Fascination with Deep Space - See more at: http://www.noodls.com/view/6061E5510....3rrRV6eS.dpuf

Just to help here given a platform with which to consider,  the question of," Dr. Poplawski from the University of New Haven, Connecticut, concluded that each time a black hole forms, a new universe could form within it."

One is always looking for evidence of such things. The very contention of black hole itself has to have had a basis with which to consider. So we may say these black holes are real.

While the subject provides many things to consider how does Dr. Poplawski provide evidence for such a statement of universe within universe?

If you look at closely at align perspectives with which to examine this it may help to look at how one is perceiving the idea of the universe? For cosmology they may say that in a coordinated system there is no before or after, just what exists as is? So any notion of what came before this universe or what is to come after is hard pill to swallow.



For some of us it is not a problem. For me then the idea is that in local regions of the universe, information is crunched in order to be dissipated in the larger universe. This supplies the motivation for expansion, and at the same time the evolving nature of the universe has to have more black holes in order to summat the existence of any cosmological constant that is to be considered positive?

The question of entropy,  as it existed in the early universe? How does this figure into the ability for any new universe to form? You are confronted with the notion of a symmetry existing in the early universe for the nature of entropy to follow the path it is today? How could any universe have existed as a fundamental reality of the current universe?






BEFORE THE BIG BANG: AN OUTRAGEOUS NEW PERSPECTIVE AND ITS IMPLICATIONS FOR PARTICLE PHYSICS

For example.

In 2010, Penrose and Vahe Gurzadyan published a preprint of a paper claiming that observations of the cosmic microwave background made by the Wilkinson Microwave Anisotropy Probe and the BOOMERanG experiment showed concentric anomalies which were consistent with the CCC hypothesis, with a low probability of the null hypothesis that the observations in question were caused by chance.[5] However, the statistical significance of the claimed detection has since been questioned. Three groups have independently attempted to reproduce these results, but found that the detection of the concentric anomalies was not statistically significant, in the sense that such circles would appear in a proper Gaussian simulation of the anisotropy in the CMB data.[6][7][8]

The reason for the disagreement was tracked down to an issue of how to construct the simulations that are used to determine the significance: The three independent attempts to repeat the analysis all used simulations based on the standard Lambda-CDM model, while Penrose and Gurzadyan used an undocumented non-standard approach.
[9]Conformal cyclic cosmology

So for some who hold entropy as a subjective examination of the reality with which we live now,  how can one exist as a viewer of the larger universe that contains all these other universe being respective of the arrow of time??
 
Can disorder precede order as a question of what came first as to the existence of the universe? The chicken or egg question. The idea then that the overarching principle here is an arrow of time, such hypothesis to consider needs a factor with which to consider such expansion being supported by some factors given to what can exist as a fundamental reality in those local regions of the universe.

Information Loss

You see, people are uncomfortable with this information loss. It’s the minority view.Pg 64, The Cyclic Universe: A Conversation with Roger Penrose

I am certainly uncomfortable with it, as I have always seen it from the idea  as to what is current in the field of discussion around blackholes and such. So there are things going on as I am reading the pdf discussion with Roger Penrose.  I am also listening to Susskind's lecture while correlating the perspective that is being talked about by Roger Penrose.





I am adding this link just for some perspective about information and the presence of an anomaly that I perceive for such rules about past and future, and the topic of will. This as it relates too, the whole gamut of the science and investigation of what truly exists in terms of information.  Most surely,  I have some issues to deal with:)

Two Paul Steinhardt Projects: "Cyclic Universe" and "Quasicrystals"



Two Paul Steinhardt Projects: "Cyclic Universe" and "Quasicrystals"






Albert Einstein Professor in Science, Departments of Physics and Astrophysical...
Quasi-elegance....As a young student first reading Weyl's book, crystallography seemed like the "ideal" of what one should be aiming for in science: elegant mathematics that provides a complete understanding of all physical possibilities. Ironically, many years later, I played a role in showing that my "ideal" was seriously flawed. In 1984, Dan Shechtman, Ilan Blech, Denis Gratias and John Cahn reported the discovery of a puzzling manmade alloy of aluminumand manganese with icosahedral symmetry. Icosahedral symmetry, with its six five-fold symmetry axes, is the most famous forbidden crystal symmetry. As luck would have it, Dov Levine (Technion) and I had been developing a hypothetical idea of a new form of solid that we dubbed quasicrystals, short for quasiperiodic crystals. (A quasiperiodic atomic arrangement means the atomic positions can be described by a sum of oscillatory functions whose frequencies have an irrational ratio.) We were inspired by a two-dimensional tiling invented by Sir Roger Penrose known as the Penrose tiling, comprised of two tiles arranged in a five-fold symmetric pattern. We showed that quasicrystals could exist in three dimensions and were not subject to the rules of crystallography. In fact, they could have any of the symmetries forbidden to crystals. Furthermore, we showed that the diffraction patterns predicted for icosahedral quasicrystals matched the Shechtman et al. observations. Since 1984, quasicrystals with other forbidden symmetries have been synthesized in the laboratory. The 2011 Nobel Prize in Chemistry was awarded to Dan Shechtman for his experimental breakthrough that changed our thinking about possible forms of matter. More recently, colleagues and I have found evidence that quasicrystals may have been among the first minerals to have formed in the solar system.

The crystallography I first encountered in Weyl's book, thought to be complete and immutable, turned out to be woefully incomplete, missing literally an uncountable number of possible symmetries for matter. Perhaps there is a lesson to be learned: While elegance and simplicity are often useful criteria for judging theories, they can sometimes mislead us into thinking we are right, when we are actually infinitely wrong.

Universal Resurrection?

 It might sound metaphysical and ominous with the idea that such a rebirth could have become the idea of a reincarnation with all that it could entail in information that is existing for the next round of universal expressions. So no,  information is never lost :-) Shall we for ever tassel for the Chicken and Egg question or accept cosmologically that the universe is as if the chick and no further questions asked?:)



Maybe you are a good practicing Catholic for what is coming with Easter?? I would never judge any individual for what their religious belief is. But yes,  I do believe that such rebirths are part of the process for our improvement, how ever such views allow us to the see the world,  it is in these new ways.  It is,  as if even our own view is an example of the world in which we will see,  as to how we are at the center of our own expressions. Not intentionally being self centered, but administrating that such births take place even within us. But that's just my point of view.

So anyway onto the scientific explanation as I see it.



 
Penrose's Conformal Cyclic Cosmology, from one of his Pittsburgh lecture slides in June, 2009. Photo by Bryan W. Roberts


Some things that came to mind are based on the idea of cyclic universe as supposed by Sir Roger Penrose. Questions outside the parameters of the cosmological universe allow for other points of view to emerge as one can surmise as not being blatantly unfair. That such a thing is as to consider "other universes" then, could become possible.  I would like to present then that the idea of the current universe is as if counted as speeding up, something within our current universe is contributing. Sean Carroll was looking for that.

To maintain such a balance as Omega (If we triangulate Omega, the universe in which we are in, Omegam(mass)+ Omega(a vacuum), what position geometrically, would our universe hold from the coordinates given?),  then is to suggest that speeding up, has components that will help to incite a geometrical presence as to how such a universe is displayed? If so,  then at a "quantum level" such contributions are being classically displayed, while forcing views with regard toward  powers of ten as to suggest, there is a much wider view here then what you see in the everyday life.

That's just part of it. So it is with this video that you might find interesting. S James Gates demonstrates a measure of time in the sense that what was historically displayed by scientists of the last hundred years can emerge within as building a systemic picture and language development which is beautiful,  while being abstract worthy of considering. This is a good example of how ones view of the world can change from what we had as always looked at the world. You find such abstractness( math structure) but there is indeed a lesson in it.

A Superset Universe?

How would you draw a Universe with all theories as being part of,  as a subset?





Pictorial representations can be very useful in presenting information or assisting reasoning. Venn diagram is an example. Venn diagrams are used to represent classes of objects, and they can also assist us in reasoning about the relations between these classes. They are named after the English mathematician John Venn (1834 - 1923), who was a fellow at Cambridge University.


A few may have taken in the link supplied to a lecture given by Thomas Campbell with regard to his MBT book he had written. Now, I was drawn to the idea of a Venn diagram presented in his lecture and the idea of how one might have use this diagram as a question about the universe and it's subsets? How would you draw it?







I give a current posting by Sean Carroll with regards to his opinion on a book written by Lawrence Krauss. So there all these theories about the nature of the universe and some scientists of course have their opinions.

............Or not, of course. We should be good empiricists and be open to the possibility that what we think of as the universe really does exist within some larger context. But then we could presumably re-define that as the universe, and be stuck with the same questions. As long as you admit that there is more than one conceivable way for the universe to be (and I don’t see how one could not), there will always be some end of the line for explanations. I could be wrong about that, but an insistence that “the universe must explain itself” or some such thing seems like a completely unsupportable a priori assumption. (Not that anyone in this particular brouhaha seems to be taking such a stance.) SEE:A Universe from Nothing?







Physicists have proposed several theories to explain why Λ is so small. One of the most popular -- the "anthropic principle" -- states that Λ is randomly set and has very different values in different parts of the universe (figure 1). We happen to live in a rare region, or "bubble", where Λ has the value we observe. This value has allowed stars, planets and therefore life to develop. However, this theory is also unsatisfactory for many scientists because it would be better to be able to calculate Λ from first principles.

Relativism

The Nobel Prize in Physics 1914 Max von Laue

I am not sure what I can add other then what I have already been saying toward logical deduction....I still need to get a handle on the essence of what is being said here in opening thread.

So with what I looked at, can we say that the deductive recognition of lets say symmetry would be in contrast to how you might look at the world in a relativistic sense versus Platonism.










See: Against Symmetry

This setting was used more I think in terms of how a scientist is explaining himself and his relationship with the way in which he had approached science.....yet I could see there were scientist who had adopted the Platonic Tradition. Example of Penrose and Coxeter were demonstrative of this idea?


5.4.3 Platonism and Relativism

Platonism is a family of views that get their name because they involve entities--propositions, properties, sets--which, like Plato's Forms, are held to be abstract, immutable things that exist outside space and time. On many platonistic approaches, concepts express abstract properties and beliefs are relations between people and abstract propositions. This suggests a way around some types of relativism, since people in quite different cultures could have many of the same beliefs (because they could believe the same abstract propositions), and a belief would be true just in case the immutable proposition it expresses is true.
The relativist may reply that platonistic accounts lead to severe difficulties in epistemology and semantics. The problem is that we are physical organisms living in a spatio-temporal world, and we cannot interact causally (or in any other discernible way) with abstract, causally inert things. Moreover, few people are aware of having any special cognitive faculty that puts them in touch with a timeless realm of abstract objects, neuroscientists have never found any part of the brain that subserves such an ability, such a view is not suggested by what is known about the ways children acquire concepts and beliefs, and nothing in physics suggests any way in which a physical system (the brain) can make any sort of contact with causally inert, non-physical objects. Moreover, if our minds cannot make epistemic contact with such things, it is difficult to see how our words and linguistic practices can make semantic contact with them.
None of this proves that abstract propositions don't exist, but it shows it isn't obvious that they do. There have been few debates between relativists and platonists over such matters, however, perhaps because the two views lie so far apart that their proponents cannot easily engage one another.

So these were two positions that were adopted within the push toward understanding the basis of science and it's mathematics.

In theory model development was pushed forward on the basis of such adoptions. Loop Quantum Gravity?

Quasicrystal: Prof. Dan Shechtman

***


Just throwing some stuff together in order to understand the extent of relativism as a universal truth, while seeking to understand the subjective realism that make up our individuality. As a layman I do not know if it will be useful under that admittance. You can judge for yourself of course.

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

If one was to solidify some basis to truth how would this be done? The question of a logic oriented view for me saw a basis in what Penrose was explaining using his Twistors, as a foundation in incorporating Fuzzy logic?

While examining the psychological model of Venn logic and TA combined, it was important that there be some relative framework for such a subjective interpretation of a logic orientated world. How subjectively could this have been managed?


Perspective of the Theoretical Scientist


So you have this history and theoretical perspective that sees the world in one way or another? How do you reduce it to a process through Computing that establishes a basis in machining the effects of [and\or-so that we say a statement is .7 true and .3 false.]? We've created a space in between a true and false statement?

DNA computing is a form of computing which uses DNA, biochemistry and molecular biology, instead of the traditional silicon-based computer technologies. DNA computing, or, more generally, molecular computing, is a fast developing interdisciplinary area. Research and development in this area concerns theory, experiments and applications of DNA computing See:DNA computing

Entanglement then provides for other understanding then of a framework that sees the interrogation of a subjective world?


Do we selectively ignore other models from artificial intelligence such as Zadeh's Fuzzy Logic? This is a logic used to model perception and used in newly designed "smart" cameras. Where standard logic must give a true or false value to every proposition, fuzzy logic assigns a certainty value between zero and one to each of the propositions, so that we say a statement is .7 true and .3 false. Is this theory selectively ignored to support our theories? Ideas on Quantum Interrogation
***

Geometry Leads us to the Truth?

Part of the realism here for me is the idea that such patterns established deep within our psyche are inherent in each of us as an image first to our awareness, but encompasses a geometric patten of sorts. This was part of the work I did on myself as I explored the realm of dreams. The idea then manifested in what was the basis of this thought process as mandala in origins. A historical vision of an ancient idea of model building. In today's world I thought this as appropriate toward how theoretical ideas are built around a whole history of science and information.

The Physics of Reality

Roger Penrose discusses his experiment on the BBC (25 minutes in)
Melvyn Bragg examines the physics of reality. When Quantum Mechanics was developed in the early 20th century reality changed forever. In the quantum world particles could be in two places at once, they disappeared for no reason and reappeared in unpredictable locations, they even acted differently according to whether we were watching them. It was so shocking that Erwin Schrodinger, one of the founders of Quantum Theory, said "I don’t like it and I'm sorry I ever had anything to do with it." He even developed an experiment with a cat to show how absurd it was.

Quantum Theory was absurd, it disagreed with the classical physics of Newton and Einstein and it clashed with our experience of the everyday world. Footballs do not disappear without reason, cats do not split into two and shoes do not act differently when we are not looking at them. Or do they? Eighty years later we are still debating whether the absurd might actually be true See: The Physics of Reality

Geometry Leads us to the Truth?

"The end he (the artist) strives for is something else than a perfectly executed print. His aim is to depict dreams, ideas, or problems in such a way that other people can observe and consider them." - M.C. Escher




I too have always been interested at the idea of what we can see deeper then what we observe on the surface. As if an abstraction in the geometry may be leading when considering Polytopes and allotrope s or even Penrose Tilings as to the Truth?:)


A remarkable mosaic of atoms

In quasicrystals, we find the fascinating mosaics of the Arabic world reproduced at the level of atoms: regular patterns that never repeat themselves. However, the configuration found in quasicrystals was considered impossible, and Dan Shechtman had to fight a fierce battle against established science. The Nobel Prize in Chemistry 2011 has fundamentally altered how chemists conceive of solid matter. See: The Nobel Prize in Chemistry 2011 Dan Shechtman
I do not think one can ever imagine what goes through my mind and I guess that's part of my artistic journey is to better learn how to describe what I am seeing. It goes back some time as to what I learn about myself and how some of these geometers see. I did not ever feel apart from them as I tried to look deeper into reality and see what the basis is and how  we might describe that.

You must also know I now sport an interesting tattoo that I will share shortly. Maybe even consider it as a line break, and as a pointer. You'll see why when I upload picture. So,  that has been my thing when I look at all this science and those espouse the teaching of,  that I tried to find my place in it. I mean I could be so wrong in a long of things.....but isn't that part of the evolution of being?  Learning about those mistakes and dealing with the responsibility of finding that truth within self?

If the heart was free from the impurities of sin, and therefore lighter than the feather, then the dead person could enter the eternal afterlife.

My second tattoo will be as in the picture showing below on this blog site demonstrating and seen above is an ancient idea about "our heart" in relation to "the truth."  How we weight that against one another and how the choices we make will have us asking whether we acted in accordance with that truth. That is "the final judgement" and if this is understood then we can access whether or not we have much more to learn. I know that setting right past mistakes is not an easy thing but if you at least start then that is part of the success of not of having to repeat them. Maybe repeat many times until you finally actually get it.

Well then,how does one simplify that picture of such Judgement in the Hall of Ma'at as to know that this message is alive and well in today's world and just as valid? How well will the tattooist portray this design? I'll have to give it to her  so she has some time to look at it and decipher.:)

Conformal Cyclic Cosmology....

Penrose's Conformal Cyclic Cosmology, from one of his Pittsburgh lecture slides in June, 2009. Photo by Bryan W. Roberts

Also see: BEFORE THE BIG BANG: AN OUTRAGEOUS NEW PERSPECTIVE AND ITS IMPLICATIONS FOR PARTICLE PHYSICS
....... (CCC) is a cosmological model in the framework of general relativity, advanced by the theoretical physicist Sir Roger Penrose.[1][2] In CCC, the universe undergoes a repeated cycle of death and rebirth, with the future timelike infinity of each previous universe being identified with the Big Bang singularity of the next.[3] Penrose outlines this theory in his book Cycles of Time: An Extraordinary New View of the Universe.

Contents

Basic Construction

Penrose's basic construction[4] is to paste together a countable sequence of open FLRW spacetimes, each representing a big bang followed by an infinite future expansion. Penrose noticed that the past conformal boundary of one copy of FLRW spacetime can be "attached" to the future conformal boundary of another, after an appropriate conformal rescaling. In particular, each individual FLRW metric gab is multiplied by the square of a conformal factor Ω that approaches zero at timelike infinity, effectively "squashing down" the future conformal boundary to a conformally regular hypersurface (which is spacelike if there is a positive cosmological constant, as we currently believe). The result is a new solution to Einstein's equations, which Penrose takes to represent the entire Universe, and which is composed of a sequence of sectors that Penrose calls "aeons."

Physical Implications

The significant feature of this construction for particle physics is that, since baryons are obey the laws of conformally invariant quantum theory, they will behave in the same way in the rescaled aeons as in the original FLRW counterparts. (Classically, this corresponds to the fact that light cone structure is preserved under conformal rescalings.) For such particles, the boundary between aeons is not a boundary at all, but just a spacelike surface that can be passed across like any other. Fermions, on the other hand, remain confined to a given aeon. This provides a convenient solution to the black hole information paradox; according to Penrose, fermions must be irreversibly converted into radiation during black hole evaporation, to preserve the smoothness of the boundary between aeons.

The curvature properties of Penrose's cosmology are also highly desirable. First, the boundary between aeons satisfies the Weyl curvature hypothesis, thus providing a certain kind of low-entropy past as required by statistical mechanics and by observation. Second, Penrose has calculated that a certain amount of gravitational radiation should be preserved across the boundary between aeons. Penrose suggests this extra gravitational radiation may be enough to explain the observed cosmic acceleration without appeal to a dark energy matter field.

Empirical Tests

In 2010, Penrose and V. G. Gurzadyan published a preprint of a paper claiming that observations of the cosmic microwave background made by the Wilkinson Microwave Anisotropy Probe and the BOOMERanG experiment showed concentric anomalies which were consistent with the CCC hypothesis, with a low probability of the null hypothesis that the observations in question were caused by chance.[5] However, the statistical significance of the claimed detection has since been questioned. Three groups have independently attempted to reproduce these results, but found that the detection of the concentric anomalies was not statistically significant.[6][7][8]

Dark circles indicate regions in space where the cosmic microwave background has temperature variations that are lower than average. The features hint that the universe was born long before the Big Bang 13.7 billion years ago and had undergone myriad cycles of birth and death before that time. See: Cosmic rebirth

Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity

Abstract: Conformal cyclic cosmology (CCC) posits the existence of an aeon preceding our Big Bang 'B', whose conformal infinity 'I' is identified, conformally, with 'B', now regarded as a spacelike 3-surface. Black-hole encounters, within bound galactic clusters in that previous aeon, would have the observable effect, in our CMB sky, of families of concentric circles over which the temperature variance is anomalously low, the centre of each such family representing the point of 'I' at which the cluster converges. These centres appear as fairly randomly distributed fixed points in our CMB sky. The analysis of Wilkinson Microwave Background Probe's (WMAP) cosmic microwave background 7-year maps does indeed reveal such concentric circles, of up to 6{\sigma} significance. This is confirmed when the same analysis is applied to BOOMERanG98 data, eliminating the possibility of an instrumental cause for the effects. These observational predictions of CCC would not be easily explained within standard inflationary cosmology.
Update:Penrose’s Cyclic Cosmology  by Sean Carroll

In response too....

More on the low variance circles in CMB sky

Abstract: Two groups [3,4] have confirmed the results of our paper concerning the actual existence of low variance circles in the cosmic microwave background (CMB) sky. They also point out that the effect does not contradict the LCDM model - a matter which is not in dispute. We point out two discrepancies between their treatment and ours, however, one technical, the other having to do with the very understanding of what constitutes a Gaussian random signal. Both groups simulate maps using the CMB power spectrum for LCDM, while we simulate a pure Gaussian sky plus the WMAP's noise, which points out the contradiction with a common statement [3] that "CMB signal is random noise of Gaussian nature". For as it was shown in [5], the random component is a minor one in the CMB signal, namely, about 0.2. Accordingly, the circles we saw are a real structure of the CMB sky and they are not of a random Gaussian nature. Although the structures studied certainly cannot contradict the power spectrum, which is well fitted by LCDM model, we particularly emphasize that the low variance circles occur in concentric families, and this key fact cannot be explained as a purely random effect. It is, however a clear prediction of conformal cyclic cosmology.

First Principles by Howard Burton



After returning home from our little vacation, I've hunkered down to read, and I thought this would be a good time to come to know of the Perimeter Institute for Theoretical Physics in Canada and how it started up.

As you know I've linked the Q2c site coming in September as well as I think after ten years this Institute has done a very good job of promoting a science based view toward the latest in the science frontiers.


Mike Lazaridis Donates Additional $50 Million to Perimeter Institute

In his remarks on behalf of the Government of Ontario, The Honourable John Wilkinson, Minister of Research and Innovation said: "Ontario's $3B Innovation Agenda focuses on our government acting as a catalyst to support our top researchers and entrepreneurs - extraordinary people like Mike Lazaridis who are leading the way to turn groundbreaking ideas and innovation into Ontario's next generation of jobs. Ontario's commitment to fundamental and applied research has not only been informed but also inspired by Mike's personal commitment to innovation, and his contributions to the Perimeter Institute. That's why our government has already invested over $65M to support this important initiative. This new investment will strengthen the Institute and the government-industry partnerships that have made it possible, and help us to continue to attract the world-class talent and the scientific knowledge Ontario needs to compete in the 21st century."See: Mike Lazaridis Donates Additional $50 Million to Perimeter Institute


Now you should know that I had received earlier notice of Howard's book from Bee of Backreaction. I have always been under the notion that what can be learnt can be learnt from all ages and there is no one aspect that we can not learn from, when we read and write about the thoughts of bloggers who have something to share with regard to their own journeys.

Bee of Backreaction writes:
The book tells the story of the first years of Perimeter Institute. From Mike Lazaridis' donation, over the search for a name, for a mission, for a location, the joy of building constructions, the hiring of the first faculty members, the establishment of PI's public outreach program, and the successful acquisition of governmental funding, to Howard's departure.

It is very entertainingly written and quite informative in addition, though I admittedly had hoped for more gossip stories about the research and the researchers. The chapter about who talked to whom when and where to pull the strings for governmental support is somewhat lengthy and tiresome, but provides interesting inside views. The book also has an amusing chapter titled "The Trouble with Physicists" about the difficulties in saving scientists from administrating themselves into dysfunctionality. I'm very tempted to quote the funniest paragraphs, but I think you should read the book yourself. It comes with some characterizations of well-known physicists that are quite to the point indeed.

The book is probably more interesting if you know some of the people involved, but besides this it conveys authentically and passionately the fascination, joy and importance of theoretical physics. Overall recommendable. If this was an Amazon review, I'd give 5 stars.
Howard Burton: First Principles


I think this is what I like most that what can be revealed in our blogging encounters, that what was written can go out toward the public to what had be done for me in the exposure of a book. I scoured the bookshop shelves for something interesting to read about science. Of course, in this case it was Howard' Burton's book First Principles.

At 5:18 PM, April 09, 2009, Blogger Plato said...

I have been watch this developing institution as well. In a weird sort of way feeling quite proud that such an institution was given impetus out of which an appreciation for developing of the science perspective was displayed here in the north, by Lazardis

I really don't think it is a Ivory Tower that is being described while Turok resides in his position. Just that what you do as a theorist is brought in line with cosmology. It's much like working the LHC and see that it is working from two perspectives, not just one.

I don't see anything wrong with that.

Nice to see a few prominent names like Susskind, Hawking and Hooft associated with PI.

When I seen the name of the book and the time you spent at PI Howard I was drawn to the idea of what Condense Matter theorists spoke of, in the same way Robert Laughlin looked at how he might describe the "foundational basis" that Phil was talking about.

Witten and others understood the condensed matter point of view as well.

Again I will read the book once finding it.


Best,


Now you must know something about this lay person who writes this blog. Previous to Howard's selective title I came across this term when I was looking for some basis as if in equatorial description that was simple to think it has some relation in algorithmic proportion that this could be the basis of all organization thought that could have exploded amongst the computer world. The very essence and core of our being as it was translated to reveal the very nature of who we are as beings.

This is when I came upon my own "Correlations of Cognition," as the condense matter theorist came to mind. I saw this relevance in how organization could be thought of at a fundamental level. Here in this case, "string theory" held my mind. So when I seen Howard's title of his book it resonated with me, for this is something that had stayed with me for years as I've remained part of the blogging experience of scientists and their engagements with each other.

How is it you then I could not learn to think, that by experiment, that one could line up two counter and oppositional points of view, to see what can be held as truth, and what remains as abstraction of the theoretical division of exploration. You know that what can reside internally as to the mode of operation as to what is self evident(arche), is something that you can place in the external world as well.

So Howard and young students become "mindful of the conduct becoming" and we see this value orientation as to the discussions between scientists. Some students become discouraged and subtle voices strain to speak,"May the ole work horses die?":)

The Book

Anyway I am on page 47 for those readers that have their books. I recognize some aspect of what Mike Lazaridis likes in Howard as to the letter he wrote, preparing the way for his future as to what? I see this fateful discerningly as to a course of action, to much in how after serving their time in the academics, that they must make their way to the financial responsibility toward providing food and sustenance to the family. No fooling around now is there.

So the letter is a spark of genius in terms of putting it out there for hire. Mike Lazaridis recognized something in himself, in what was written by Howard Burton. Mike Lazaridis although an engineer, was was much like him? Avenues to freedom then were the ability to put together a plan once accepting the job, and Howard ability to get to work even though it didn't seem like Howard Burton had a job, was exactly what Mike seem to me what he was looking for.

I liked Chris Isham too, in his explanations, and toward this regard, Chris Isham reminded me of Penrose. I found it kind of odd that later on as Howard is making his way gathering information on Institutes that when again visiting Isham that there was a distance and unknowing attribute of who Howard was? I find this strange when mentioning about his wife and who was meet first as to consequence of saying?

Stargazers and Hill Climbers

AS with Einstein, who was Socrates daemon?:)

In Plato's Apology of Socrates, Socrates claimed to have a daimonion (literally, a "divine something")[6] that frequently warned him - in the form of a "voice" - against mistakes but never told him what to do
See:Fullerane and Allotropes

Some may even call "hills" mountains. Depends on where they think perspective is heighten in relation to where they see themself in the world, and where a better locations allows for a more expansive views of things. This is psychologically important to realize that inherent inside of us if one does follow the tenet of Know Thyself by Socrates. Such a plan would have been understood in the examination to see a relationship in continuity is topologically important with the world around them. Not be self-centred, but to move progressively in the world may call for understanding this relationship with the environment.

What shall proceed the understanding that the arche is fully understood as the central themes of characters, to see it exemplified in how you now approach the world in your own way? It becomes easier for you to understand, that this "imprint of the concrete in the painting I had selected of the Raphael" was to show such a school of thought, was exemplifying the truer principle of the wisdom seeking, while of course approaching the modern day world based on that Socratic method in science.

But I only show by example, and recognizing this facet of the nature of the individual is more the idea that what ever method you choose that it is consistent and recognizable, becomes second nature to the person seeking answers. Student of Science or Philosophy.

Death of Socrates by Jacques Davidthis picture depicts the closing moments of the life of Socrates. Condemned to death or exile by the Athenian government for his teaching methods which aroused scepticism and impiety in his students, Socrates heroicly rejected exile and accepted death from hemlock.

Self portrait of Jacques-Louis David, 1794, Musée du Louvre

Here the philosopher continues to speak even while reaching for the cup, demonstrating his indifference to death and his unyielding commitment to his ideals. Most of his disciplines and slaves swirl around him in grief, betraying the weakness of emotionalism. His wife is seen only in the distance leaving the prison. Only Plato, at the foot of the bed and Crito grasping his master's leg, seem in control of themselves.
See:Jacques-Louis David: The Death of Socrates

I think the idea is and can be unique, in that each can develop a process and means to an end( many travel far and wide while they should have never left home), that would allow this creative aspect of being "in the now" has potential. To be able to allow insight to manifest and spread across the mind in such lightning speed. It thusly leaves no doubt. This is a condensible feature of the complexity of information to be distill to it's essence. IN an abstract world, a rain drop can hold quite an lot of architectural meaning.

For Plato then it was the ideal city-state of Kallipolis

The Philosopher King
Plato defined a philosopher firstly as its eponymous occupation – wisdom-lover. He then distinguishes between one who loves true knowledge as opposed to simple sights or education by saying that a philosopher is the only man who has access to Forms – the archetypal entities that exist behind all representations of the form (such as Beauty itself as opposed to any one particular instance of beauty). It is next and in support of the idea that philosophers are the best rulers that Plato fashions the ship of state metaphor, one of his most often cited ideas (along with his allegory of the cave). "[A] true pilot must of necessity pay attention to the seasons, the heavens, the stars, the winds, and everything proper to the craft if he is really to rule a ship" (The Republic, 6.488d). Plato claims that the sailors (i.e., the people of the city-state over whom the philosopher is the potential ruler) ignore the philosopher's "idle stargazing" because they have never encountered a true philosopher before.


Stargazers by Paul Rossetti Bjarnson, Pg 102, Chapter XV

Ever teacher has their progeny of students as has been exemplified in the context of our modern day scholars. Kip Thorne in relation to John Archibald Wheeler. Stephen Hawking and his doctoral students.

Dennis William Siahou Sciama FRS (November 18, 1926–December 18, 1999) was a British physicist who, through his own work and that of his students, played a major role in developing British physics after the Second World War.

Sciama also strongly influenced Roger Penrose, who dedicated his The Road to Reality to Sciama's memory. The 1960s group he led in Cambridge (which included Ellis, Hawking, Rees, and Carter), has proved of lasting influence.


I have already established this lineage and subsequent comments in relation to Penrose under this heading to exemplify the relationship and perspective in relation to each other externally in the progressive nature of moving forward in science.

For Plato, it is no less an important feature that at Socrates bedside he sees the wisdom of his teacher become the "guiding light source" of all that must exchange between those who hold a value to "dimensional significance in abstract" in our current day, would be able to see the world in a most significant way. It's no less progressive then, that such an example was given to an extent that the thought process of the Gendankin, would be set before Plato's own students, as John Wheeler did for his, to see that Aristotle is most selectively announced as a most brilliant student by answering to Plato's analogy of the Cave. Who becomes an extension of the "arche in principle" as one end being science, and in a open sweeping hand, to all that is for ever exemplify in the "arche contained" in the heading of this blog above.

Plotinus

Plotinus (Greek: Πλωτῖνος) (ca. AD 204–270) was a major philosopher of the ancient world who is widely considered the founder of Neoplatonism (along with his teacher Ammonius Saccas). Much of our biographical information about him comes from Porphyry's preface to his edition of Plotinus' Enneads.

Plotinus Theory

Plotinus taught that there is a supreme, totally transcendent "One", containing no division, multiplicity or distinction; likewise it is beyond all categories of being and non-being. The concept of "being" is derived by us from the objects of human experience called the dyad, and is an attribute of such objects, but the infinite, transcendent One is beyond all such objects, and therefore is beyond the concepts that we derive from them. The One "cannot be any existing thing", and cannot be merely the sum of all such things (compare the Stoic doctrine of disbelief in non-material existence), but "is prior to all existents". Thus, no attributes can be assigned to the One. We can only identify it with the Good and the principle of Beauty. [I.6.9]

For example, thought cannot be attributed to the One because thought implies distinction between a thinker and an object of thought (again dyad). Even the self-contemplating intelligence (the noesis of the nous) must contain duality. "Once you have uttered 'The Good,' add no further thought: by any addition, and in proportion to that addition, you introduce a deficiency." [III.8.10] Plotinus denies sentience, self-awareness or any other action (ergon) to the One [V.6.6]. Rather, if we insist on describing it further, we must call the One a sheer Dynamis or potentiality without which nothing could exist. [III.8.10] As Plotinus explains in both places and elsewhere [e.g. V.6.3], it is impossible for the One to be Being or a self-aware Creator God. At [V.6.4], Plotinus compared the One to "light", the Divine Nous (first will towards Good) to the "Sun", and lastly the Soul to the "Moon" whose light is merely a "derivative conglomeration of light from the 'Sun'". The first light could exist without any celestial body.


While the arche then becomes a understanding and significant addition to ever place that self evident becomes real for the individual then how is it that such an relation cannot be seen in the world as a foundation principle to guarantee that they are on the right track. To see that "correlation of cognition" places a role in the factual attainment of information. No matter how insignificant or trivial the relation, as common knowledge, it becomes a reinforcing measure of how one is adapting and applying this model, which allows confidence to be built in pursuance of knowledge and truth.

The Plane of Simultaneity

This blog entry was constructed to reply to the conversation that is going on in the issue of the "Block Universe."


See:

  • Penrose and Quanglement

  • Entanglement and the New Physics




  • In the past, teleportation has only been possible with particles of light Image: Rainer Blatt



    It's useless sometimes to just lay there while these thoughts accumulate in one's mind, as one weaves together the picture that is forming, and whence it come from this unification process, and after a time, one then thinks about the abilities of mind to gather and consolidate.


    By taking advantage of quantum phenomena such as entanglement, teleportation and superposition, a quantum computer could, in principle, outperform a classical computer in certain computational tasks. Entanglement allows particles to have a much closer relationship than is possible in classical physics. For example, two photons can be entangled such that if one is horizontally polarized, the other is always vertically polarized, and vice versa, no matter how far apart they are. In quantum teleportation, complete information about the quantum state of a particle is instantaneously transferred by the sender, who is usually called Alice, to a receiver called Bob. Quantum superposition, meanwhile, allows a particle to be in two or more quantum states at the same time


    So let me begin first by saying that given this process we can connect this world line across the expanse of space, is, more or less the understanding that this is to be the means in which these new forms of communication in science are leading as we expound the future, and what it shall become in our present moments.



    See: Central theme is the Sun You can "click" on picture as well, or, use mouse to hover over image, for additional reading

    So you look at the sun, and what new ways can we can perceive and accumulating the data of what connects this "distance and time," one will be all the smarter when they realize that the results of experimental verifications are at present being given, and as such, what shall these examples serve, but to remind one that new experiences continue to bring new innovations to the forefront.

    Lightcone Projection- see mathematical basis here for the introduction of what will become the basis of determinations, the "decomposable definition" of these new forms of communication.

    The basis for these thoughts are the developing views based on the light cone. It was not my reasons alone in which such an idea was used to support an conjecture about, so, by these very reasons I thought it best to explain what such simultaneity can do as we hold these views about "distance and time" as we follow this world line across the expanse of the universe.

    The grey ellipse is moving relativistic sphere, its oblate shape due to Lorentz contraction. Colored ellipse is visual image of the sphere. Background curves are a xy-coordinates grid which is rigidly linked to the sphere. It is shown only at one moment in time.See here for reference and animations.

    Okay, so we have this event that happens in time. How are we to measure what the sun is suppose to be, if we did not have some information about the depth of perception that is needed in order to create this image for consumption?

    Such comparative views are needed that are current, and, "in experimental stages" to help us discern what it means for "Galactic Communication" which we will employ as we measure the distance of this world line.:)

    Such distances "can be elevated in my view," and such instantaneous recognitions are to be the associative values I place on how we can now see the "bulk perspective" and the graviton's condensation we can now assign to the cosmos?

    As we know from Einstein’s theory of special relativity, nothing can travel faster than c, the velocity of light in a vacuum. The speed of the light that we see generally travels with a slower velocity c/n where n is the refractive index of the medium through which we view the light (in air at sea level, n is approximately 1.00029 whereas in water n is 1.33). Highly energetic, charged particles (which are only constrained to travel slower than c) tend to radiate photons when they pass through a medium and, consequently, can suddenly find themselves in the embarrassing position of actually travelling faster than the light they produce!

    The result of this can be illustrated by considering a moving particle which emits pulses of light that expand like ripples on a pond, as shown in the Figure (right). By the time the particle is at the position indicated by the purple spot, the spherical shell of light emitted when the particle was in the blue position will have expanded to the radius indicated by the open blue circle. Likewise, the light emitted when the particle was in the green position will have expanded to the radius indicated by the open green circle, and so on. Notice that these ripples overlap with each other to form an enhanced cone of light indicated by the dotted lines. This is analogous to the idea that leads to a sonic boom when planes such as Concorde travel faster than the speed of sound in air
    See:What is Cerenkov Radiation?

    It is thusly, that such events in time produce information for us, that help us to look at the universe in new ways, and as such, information can be used to build new devices that penetrate beyond the confines we finds photons experience in their limitations.( please Phil take note of, in bold)
