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.

A Penrose tiling (P3) using thick and thin rhombi. Note the aperiodic structure, shared by all Penrose tilings. This particular Penrose tiling exhibits exact five-fold symmetry.

A Message from your Future Self.

I know if you are a scientist this does not equate to anything of value that can be assigned by any measure. So lets be clear here. So,  other then to say,  that any move toward identifying this aspect of self, it is always present and available to our observing, as a process of introspection. If you are going to say that such time travel does not exist in that forward sense, how would/could we really know?

So while there is not much given to the attribution of any real science here, I thought,  if given to such wondering of my mind, then what would happen to the arrow of time(well nothing since there is no real science)? How would this run in contradiction too, what science has to say about it? So if your a scientist how if possible could this ever be true?

The ability of our perception to see in advance would be to have our perceptions run backward in time and to see that this Future self, has an ability to see all that forgoes in the movement forward as to the soul's progressions. Show what it will become,  if it has the ability to see backward in time and to have the ability of to move forward in time.

The elusiveness of this perception of seeing,  from another perspective is intriguing to me.  This wondering is providing some background as to where and how we can recognize that future self.  What wisdom shall flow through back to this time in my life with which to provide incentive. Which is to provide meaning and to understand what I have become,  in that future time. Here in then lies attributes of the forgetfulness as too, what any future self shall see if each segment of the time/space allotted holds "a blanket over" each space time.

I have always argued that this ability of wisdom to be in all of us, then,  takes on new meaning here as I explore the nature and thoughts about this Future self. The Future self then,  is the Higher self. While I had attributed this to the archetypes with which we create, then how does our ability of mind to use metaphorical and subjective symbols too,  "send a message" to our now.

The Fly's Eye

The concept is intriguing when it comes to how movement can been seen and some of the technologies that had used this very concept. But there is something more here then first seen by people that attracted my attention.

An image of a house fly compound eye surface by using scanning electron microscope

A compound eye may consist of thousands of individual photoreceptor units or ommatidia (ommatidium, singular). The image perceived is a combination of inputs from the numerous ommatidia (individual "eye units"), which are located on a convex surface, thus pointing in slightly different directions. Compared with simple eyes, compound eyes possess a very large view angle, and can detect fast movement and, in some cases, the polarisation of light.^[24] (Even the trained human eye can determine the orientation of polarized light which manifests in a phenomenon called Haidinger's brush.) Because the individual lenses are so small, the effects of diffraction impose a limit on the possible resolution that can be obtained (assuming that they do not function as phased arrays). This can only be countered by increasing lens size and number. To see with a resolution comparable to our simple eyes, humans would require very large compound eyes, around 11 m in radius.^[25]

Compound eyes fall into two groups: apposition eyes, which form multiple inverted images, and superposition eyes, which form a single erect image.^[26] Compound eyes are common in arthropods, and are also present in annelids and some bivalved molluscs.^[27] Compound eyes, in arthropods at least, grow at their margins by the addition of new ommatidia.^[28]

I draw attention to the idea of polarization of light for obvious reasons especially when it comes to communication aspect of light transference. I know there are some who are better educated here.The question is to understand how any sensor that can pick up light differentiation,  as if,  the sun sweeps across the sky. You would understand that connected to this very focus then is the ability to pick up the very differentiation of light? You see?

If you know how to do that, then how would light communication affect receivers of information that is being broadcasted in the light? There is so much to consider here and that information is contained within this very blog.

Lifi and 5g: Optical Communications

Visible light is only a small portion of the electromagnetic spectrum.

I have been away a while getting caught up on some work and enjoying some vacation time. I am always exciting about where we are going next in terms of communication development. Some of these previews  have been show here in various blog posts, that you can preview with label access.

The United States 700 MHz FCC wireless spectrum auction was started by the FCC on January 24, 2008 for the rights to operate the 700 MHz frequency band in the United States. The details of process were the subject of debate between several telecommunications companies, including Verizon Wireless, AT&T, and startup Frontline Wireless, as well as the Internet company Google. Much of the debate swirled around the "open access" requirements set down by the Second Report and Order released by the FCC determining the process and rules for the auction. All bidding must be commenced by January 28 by law. The auction was named Auction 73.[1]

The interesting thing here in terms of development is that the industry is still in a sort of infancy where those who are quite brave in terms of their science and knowledge back ground can contribute and create a different type of communication base that is current residing outside of government regulations right now. The spectrum allocation is currently not licensed and using that platform if you can develop it create the possibility of networks that do not currently reside in spectrum allocation that are being sold.?

Li-Fi, or "light fidelity", is a technology, that can be a complement of RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting. Li-Fi, like Wi-Fi, is the high speed, bidirectional and fully networked subset of visible light communications (VLC). It is wireless and uses visible light communication (instead of radio frequency waves), which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.^[1]

 While we know the ground rules of communication are limited in terms of wifi, the future is quite as to how information can be disseminated and how much of it can be accessed through new technology that will reside outside of the devices that currently are being adapted too, to use that type of communication. So I encourage new development here if you have the brains and brawn in order to tackle that new fledgling business of the future.

 It is a 5G^[2] visible light communication system that uses light from light-emitting diodes (LEDs) as a medium to deliver networked, mobile, high-speed communication in a similar manner as Wi-Fi.^[3] Li-Fi could lead to the Internet of Things, which is everything electronic being connected to the internet, with the LED lights on the electronics being used as Li-Fi internet access points.^[4] The Li-Fi market is projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 billion per year by 2018.^[5]

It is a sobering thought to thing of the optical side of things of having such a wide market growth, with the potential of money development, but at the same time brings to light the development that is currently and has yet to become marketable through innovation and technological design. So I encourage the young folk coming out of universities to explore at least from their educative perspective and expertise this area of communication and technological design..

pureLiFi is at the forefront of research and commercialisation into Li-Fi, an industry expected to grow from $100 million to $6 billion by 2018. Visible Light Communication (VLC) is the use of light to transmit data wirelessly. Li-Fi - a term coined by pureLiFi’s Chief Science Officer and co-founder, Professor Haas – is a technology based on VLC that provides full networking capabilities similar to Wi-Fi, but with significantly greater spatial reuse of bandwidth. See: pureLiFi to demonstrate first ever Li-Fi system at Mobile World Congress

Suspension of Judgement-Self Evident

The regress argument (also known as the diallelus (Latin < Greek di allelon "through or by means of one another")) is a problem in epistemology and, in general, a problem in any situation where a statement has to be justified.^[1][2][3]
According to this argument, any proposition requires a justification. However, any justification itself requires support. This means that any proposition whatsoever can be endlessly (infinitely) questioned, like a child who asks "why?" over and over again.

Origin

The argument is usually attributed to Sextus Empiricus, and has been restated by Agrippa as part of what has become known as "Agrippa's trilemma". The argument can be seen as a response to the suggestion in Plato's Theaetetus that knowledge is justified true belief.

Structure

Assuming that knowledge is justified true belief, then:

1. Suppose that P is some piece of knowledge. Then P is a justified true belief.
2. The only thing that can justify P is another statement – let's call it P₁; so P₁ justifies P.
3. But if P₁ is to be a satisfactory justification for P, then we must know that P₁.
4. But for P₁ to be known, it must also be a justified true belief.
5. That justification will be another statement - let's call it P₂; so P₂ justifies P₁.
6. But if P₂ is to be a satisfactory justification for P₁, then we must know that P₂ is true
7. But for P₂ to count as knowledge, it must itself be a justified true belief.
8. That justification will in turn be another statement - let's call it P₃; so P₃ justifies P₂.
9. and so on, ad infinitum.

Since being a layman,  I am finding my way through my own beliefs in the constructive mechanisms of philosophy which seem to be produced at almost every turn. To continue learning, and while holding suspension of Judgement  from what is self evident,  plays to the role of where Foundationalism and  Coherentism (see also: Coherentism) reside. Hopefully being,  by my assumption,  as to being accurate within the instructions detailed by way of the mechanism implied by Philosophy. My head is spinning. I mean, can I have found myself relieved of such constraints to have finally said, "Ataraxia (ἀταραξία "tranquility") is a Greek term used by Pyrrho and Epicurus for a lucid state of robust tranquility, characterized by ongoing freedom from distress and worry.^[1]"

 Ataraxia (cont.)

For the Epicureans

For the Epicureans, ataraxia was synonymous with the only true happiness possible for a person. It signifies the state of robust tranquility that derives from eschewing faith in an afterlife, not fearing the gods because they are distant and unconcerned with us, avoiding politics and vexatious people, surrounding oneself with trustworthy and affectionate friends and, most importantly, being an affectionate, virtuous person, worthy of trust.^{[citation needed]}

For the Pyrrhonists

For the Pyrrhonists, given that neither the sense impressions nor the intellect, nor both combined, is a sufficient means of knowing and conveying truth, one suspends judgement on dogmatic beliefs or anything non-evident. It is from this suspension of belief Ataraxia arises as one realizes one thing is 'no more' than that. No more up than down, no more wet than dry, no more hot than cold, no more night than day, "the number of stars one can see in the night sky is no more even than odd", no more left than right, no more black than white as when Anaxagoras countered the notion that snow is white with the argument "Snow is frozen water, and water is black; therefore snow is also black", etc. Most important of all, in enunciation of 'no more' or 'I determine nothing', in uttering these expressions, one is merely stating how things appear to them, at the time and in an undogmatic way, without making any assertion of truth regarding external reality.^[2]

For the Stoics

The Stoics, too, sought mental tranquility, and saw ataraxia as something to be highly desired and often made use of the term, but for them the analogous state, attained by the Stoic sage, was apatheia or absence of passion.^[3]

Rest assuredly,  I have not reach that state of "apatheia or absence of passion," with which a Stoic is as if, one may have found in them self to be.
