Quantum Lorem Ipsum

I got tired of Lorem Ipsum text and created Quantum Lorem Ipsum, now with 100% more physics jargon!

To those who are not familiar, Lorem Ipsum is a piece of latin text, comprised of multiple paragraphs, that is used as a placeholder during the design process of building a page layout. It allows the designer to focus on the geometric aspects of the layout, optically test typographical hierarchy, assess legibility, calculate margins, etc. without having the final content of the text from the writing department. Thus, the design process can be developed concurrently while the content is being produced.

Word Length Distribution

Despite of technical nature of the words, which presumably makes them longer; above density graph shows that Quantum Lorem Ipsum has fewer longer words than Lorem Ipsum. The argument against using gibberish, unrecognizeable, symantically obfuscated piece of text such as the original Lorem Ispum, is that the quantum version of it provides realism (at the expense of diverting attention from the design process) and I find it optically "correct".

A number of times when desiging a page layout, I've come across moments where the design is optimized and in final stages of development; content is delivered and flown into the cascading text blocks and ... the result has changed. It no longer appears "correct". It is difficult to describe it in words. The following are two paragraphs in latin and english. Both are equally meaningless at the end, but latin is gibberish at the word-recognition level and english is gibberish at the sentence-recognition level.

Etiam hendrerit pretium massa, sed pulvinar lorem ultrices in. In luctus  sagittis ante ut consequat. Aliquam erat volutpat. Cras ac sollicitudin  urna. Aenean dapibus lorem sed felis fermentum suscipit. Morbi sed  sapien eros. Suspendisse eu tempor arcu.

The disguised common can't watch the piano. Is the fold guest better than the location? It was then the good system met the annual funny. The vacuous formal reports into the breakable formal. It was then the instinctive negotiation met the realistic evidence.

So, why does the english version appear to have a better structure? I presume it has something to do with the way word recognition works in the visual/auditory pathways of the brain [1]. In the english paragraph which is obviously meaningless, our brain recognizes overall shapes of words and the relationship between them. At some later time in the pipeline, the limbic system tries to make sense of the sentence, we have an uncaught exception (in computer programming lingo): the visual system was happy with it, from V1-V5 regions of the brain do not catch symantic exceptions, that happens, I am guessing, in the fusiform-gyrus based on some of the things Dr. V.S. Ramachandran, a neuroscientist at the UC San Deigo, has presented in his talk repetoire.

I think the design process, especially when dealing with typography and legibility, using realistic text is preferable, despite of what the underlying reason for its preference may be. Here is it is in its full glory, released until MIT license. The source of the material is various scientific texts hosted on Wikibooks.

Quantum Lorem Ispum Text

The fundamental concepts of classical physics, space, time, mass, and derived concepts, velocity, momentum, force, angular momentum, energy ... all rest on the principle that material points have trajectories. They are defined as lines in space-time. Even the dynamics of continuous, solid or fluid media describes the trajectories of the material points which constitute the bodies in motion. But the indeterminacy relation of Heisenberg prevents quantum particles from having such classical trajectories, since their position and velocity can not be exactly defined at the same time. How then can it explain all the appearances which legitimize the fundamental concepts of classical physics?

Systems, in one sense, are devices that take input and produce an output. A system can be thought to operate on the input to produce the output. The output is related to the input by a certain relationship known as the system response. The system response usually can be modeled with a mathematical relationship between the system input and the system output.

The principle of relativity states that all inertial systems are "created equal": the laws of physics are the same as long as they are formulated with respect to an inertial frame — no matter which. The first three items tell us that one inertial frame is as good as any other frame as long as the other frame differs by a shift of the coordinate origin in space and/or time and/or by a rotation of the spatial coordinate axes. What matters in physics are relative positions, relative times, and relative orientations (the orientations of objects relative to each other), inasmuch as these are unaffected by translations in space and/or time and by rotations of the spatial axes. In the physical world, there are no absolute positions, absolute times, or absolute orientations.

Physical systems can be divided up into a number of different categories, depending on particular properties that the system exhibits. Some of these system classifications are very easy to work with and have a large theory base for analysis. Some system classifications are very complex and have still not been investigated with any degree of success. By properly identifying the properties of a system, certain analysis and design tools can be selected for use with the system.

Electronic modes (their polarization features are described by Spin 1/2) are calculated by the Dirac equation, or, to a very good approximation in cases where the theory of relativity is irrelevant, by the Schrödinger equation and the Pauli equation. Modes of Spin 0 would be calculated by the Klein-Gordon equation. In order to calculate the modes exposed to potentials that attract or repulse the waves or, equivalently, exposed to a change in refractive index and wave impedance, or exposed to magnetic fields, there are several equations depending on the polarization features of the modes.

The postulate of the reduction of the state vector denies the existence theorem of multiple destinies. If an observation really leads to the collapse of the state vector then we only have a single destiny. The postulate of the collapse of the state vector allows us to preserve our prejudice, that the other destinies do not exist. It is its only justification. There are no others. We introduce a contradiction into the heart of quantum theory because we do not want to believe in other destinies, because we do not accept that reality could be more than what we can directly observe.

If one takes quantum physics seriously, if one believes that it correctly describes reality, if one thus accepts the existence theorem of multiple destinies, one does not need the postulate of the collapse of the state vector. The principle of unitary evolution is sufficient to describe reality.

Depending on the point of view chosen, it can be said that the observations are entangling or disentangling. They are entangling because they lead to an entanglement between the observed system and the observer. They are disentangling because they lead to an apparent collapse of the state vector of the observed system. On the other hand, the coherence of the superpositions of eigenstates associated with the same result is not destroyed by an ideal measurement. The subspaces of such eigenstates are free of decoherence.

The first rule is typical of quantum physics. It results from the postulate of unitary evolution. The second rule is a classical rule of addition of probabilities. It results from decoherence through observation. When intermediate states are observed, the observed system is represented by a mixture of states. The classical rule of addition of probabilities must then be applied. Entanglement by observation thus explains Feynman's second rule. This explains the Feynman Rules for calculating probabilities in quantum physics (Feynman 1966).

When a measurement is ideal, the eigenstates of the measurement are not disturbed by the observation. For there to be communication, or transport of information, there must be an action or an interaction which travels at the speed of light or at a lower speed. When a distant part of an entangled pair is observed, there is no interaction with the unobserved part. No measurable effect of the former on the latter can be detected.

The state space of the whole space is the tensor product of the state spaces of the regions in which it has been decomposed. The state vector of the universe thus describes the entanglement between all regions of space (Wallace 2012). But it describes the multiple destinies of all beings in the universe. Most of these destinies are separated and can never meet, while they occur in the same space and sometimes in the same places. This poses a difficulty of principle: why say of two destinies that they pass by the same place if they can not meet there?

Einstein could not believe that quantum physics gives a complete description of reality because he did not want to give up the principle of the separability of reality. All classical physics respects the principle that the state of the system is always to be identified with the list of states of its parts. To speak of an entangled state, of a defined state of a system in which the parts have no definite state, has no meaning in classical physics.

When a quantum system is not a macroscopic measuring instrument or an ideal observer, no pointer state basis is privileged (see 5.5). One can still define multiple destinies by arbitrarily choosing one of its bases of states. But there is no reason to think that these destinies are real, because the states which define them are not, in general, states by which the system really passes. In reality it is in a superposition of these states or in a state entangled with the environment. This is why this book call them virtual quantum destinies.

Another fundamental reason prevents the identification of Feynman paths with real destinies. They would attribute very many pasts to the same present state. Feynman paths do not form a tree structure because they can converge as easily as they diverge. A quantum state on a Feynman path is a point of convergence of many paths that would define as many pasts if they were real destinies. This property of convergence of virtual destinies is important to make use of the parallelism of quantum computation, but it seems obviously excluded for real destinies, which in general seem to have a single past.

The formalism of the unitary operators implicitly uses the concept of time, since a unitary operator describes a change of state, but it says nothing a priori about space and mass. It seems falsely that space and mass are essentially classical concepts, that quantum physics does not explain their existence, and that therefore it can not explain by itself the classical appearances of the world. Most quantum equations have classical equivalents and we need the second ones to understand the first. Thus presented quantum physics is not autonomous in relation to classical physics, it is only a very particular way of using concepts borrowed from classical physics.

We can thus construct models of the Universe in which the worlds relative to the observers have a classical appearance. The quantum evolution of the Universe can not be identified with a classical destiny, but it is enough to determine the growth of a forest of destinies of observers and their relative worlds. Quantum physics explains classical appearances without postulating that the Universe itself must have this appearance. It shows how classical appearances relative to observers emerge from a quantum evolution which describes a forest of multiple destinies.
