CHINA IN SPACE AND TIME

From the West, we tend to judge today’s China more by its economic presence and the impact of its material development on the rest of the world than by the internal needs in the development of its history; thus giving an overwhelming priority to the geopolitical perspective over the cultural one, which should have at least a comparable importance.

In fact, it is easy to see that China’s overall impact will depend to a large extent on how well it manages to fit this whole period and the foreseeable future into a historical framework for which it would like as little change as possible. A sense of continuity on a large scale is fundamental to Chinese culture, and in the long term it will always do its best to assimilate and make the origin of foreign influences undetectable. It has already achieved this to a large extent with Marxism and capitalism, which lose so much of their original meaning in translation that it is no longer known whether to call the Chinese system “market socialism” or “state capitalism”.

Two kinds of reciprocity

The Taijitu, the emblem of the action of the Pole with respect to the world, and of the reciprocal action with respect to the Pole, inevitably reminds us of the most universal figure in physics; we are naturally referring to the ellipse —or rather, it should be said, to the idea of the generation of an ellipse with its two foci, since here there is no eccentricity. The ellipse appears in the orbits of the planets no less than in the atomic orbits of the electrons, and in the study of the refractive properties of light it gives rise to a whole field of analysis, ellipsometry. Kepler’s old problem has scale invariance, and plays a determining role in all our knowledge of physics from the Planck constant to the furthest galaxies.

In physics and mechanics, the principle of reciprocity par excellence is Newton’s third principle of action and reaction, which is at the base of all our ideas about energy conservation and allows us to “interrogate” forces when we are obliged to assume the constancy or proportionality of other quantities. The third principle does not speak of two different forces but of two different sides of the same force.

Now, the story of the third principle is curious, because we are forced to think that Newton established it as the keystone of his system to tie up the loose ends of celestial mechanics —particularly in Kepler’s problem- rather than for down-to-earth mechanics based on direct contact between bodies. The third principle allows us to define a closed system, and closed systems have been the given for all fundamental physics since then —however, it is precisely in celestial orbits, such as that of the Earth around the Sun, that this principle can be least verified, since the central body is not in the center, but in one of the foci. The force designated by the vectors would have to act on the void, where there is no matter.

Since the very first moment it was argued in the continent that Newton’s theory was more an exercise in geometry than in physics, although the truth is that, if physics and vectors were good for something, the first thing that failed was geometry. That is, if we assume that forces act from and on centers of mass, instead of on mere mathematical points. But, despite what intuition tells us —that an asymmetric ellipse can only result from a variable force, or from a simultaneous generation from the two foci-, the desire to expand the domain of calculus prevailed over anything else.

In fact the issue has remained so ambiguous that attempts have always been made to rationalize it with different arguments, either the system’s barycenter, or the variation in orbital velocity, or the initial conditions of the system. But none of them separately, nor the combination of the three, allows to solve the issue satisfactorily.

Since no one wants to think that the vectors are subjected to quantitative easing, and they lengthen and shorten at convenience, or that the planet accelerates and brakes on its own as a self-propelled rocket, in order to keep the orbit closed, physicists finally came to accept the combination in one quantity of the variable orbital speed and innate motion. But what happens is that if the centripetal force counteracts the orbital velocity, and this orbital velocity is variable despite the fact that the innate motion is invariable, the orbital velocity is in fact already a result of the interaction between the centripetal and the innate force, and then the centripetal force is also acting on itself. Therefore, the other options being ruled out, what we have is a case of feedback or self-interaction of the whole system.

So it must be said that the claim that Newton’s theory explains the shape of the ellipses is at best a pedagogical resource. However, this swift pedagogy has made us forget that our so called laws do not determine or “predict” the phenomena we observe, but try to fit them at most. Understanding the difference would help us to find our place in the overall picture.

The reciprocity of Newton’s third principle is simply a change of sign: the centrifugal force must be matched by an opposing force of equal magnitude. But the most elementary reciprocity of physics and calculus is that of the inverse product, as already expressed by the formula of velocity, (v = d/t), which is the distance divided by time. In this very basic sense, those who have pointed out that velocity is the primary fact and phenomenon of physics, from which time and space are derived, are absolutely right.

The first attempt to derive the laws of dynamics from the primary fact of velocity is due to Gauss, around 1835, when he proposed a law of electric force based not only on distance but also on relative velocities. The argument was that laws such as Newton’s or Coulomb’s were laws of statics rather than of dynamics. His disciple Weber refined the formula between 1846 and 1848 by including relative accelerations and a definition of potential —a retarded potential, in fact.

Weber’s electrodynamic force is the first case of a complete dynamic formula in which all quantities are strictly homogeneous or proportional [8]. Such formulas seemed to be exclusive to Archimedes’ statics, or Hooke’s elasticity law in its original form. In fact, although it is an specific formula for electric charges and not a field equation, it allows to derive Maxwell’s equations and the electromagnetic fields as a particular case, simply integrating over volume.

The logic of Weber’s law could be applied equally to gravity, and in fact Gerber used it to calculate the precession of Mercury’s orbit in 1898, seventeen years before the calculations of General Relativity. As is well-known, General Relativity aspired to include the so-called “Mach principle”, although in the end it did not succeed; but Weber’s law was entirely compatible with that principle in addition to explicitly using homogeneous quantities, well before Mach wrote about these issues.

It has been said that Gerber’s argument and equation was “merely empirical”, but in any other era not having to create ad hoc postulates would have been seen as the best virtue. In any case, if the new proportional law was used to calculate a tiny secular divergence, and not for the generic ellipse, it was for the simple reason that in a single orbital cycle there was nothing to calculate for either the old or the new theory.

Weber’s purely relational formula cannot “explain” the ellipse either, since force and potential are simply derived from motion —but at least there is nothing unphysical in the situation, and the fulfillment of the third principle is guaranteed while permitting a deeper meaning.

Ironically, as this new law changed the prevailing idea of central forces, understood with a string attached, Helmholtz and Maxwell blamed Weber’s law for not complying with energy conservation, although finally in 1871 Weber showed that it did so on the condition that the motion was cyclical —which in this issue was already the basic requirement for Newtonian or Lagrangian mechanics too. Conservation is a global property, not a local one, but the same was true for the orbits described in the Principia, not less than those of Lagrange. Strictly speaking there is no local conservation of forces that can make physical sense. Newton himself used the analogy of a slingshot, following Descartes’ example, when he spoke of the centrifugal motion, but nowhere in his definitions is there any talk that the central forces should be understood as if connected by a string. However, posterity took the simile at face value.

Why claim that there is in any case feedback, self-interaction? Because all gauge fields, characterized by the invariance of the Lagrangian under transformations, are equivalent to a non-trivial feedback between force and potential —the eternal “information problem”, namely how does the Moon know where the Sun is and how does it “know” its mass to behave as it does.

Indeed, if the Lagrangian of a system —the difference between kinetic and potential energy – has a certain value and is not equal to zero, this is equivalent to say that action-reaction is never immediately fulfilled. However, we use to assume that Newton’s third principle is immediate and takes place automatically and simultaneously, without mediation of any time sequence, and the same simultaneity is assumed in General Relativity. The presence of a retarded potential indicates at least the existence of a sequence or mechanism, even if we can not say anything else about it.

This shows us that additive and multiplicative reciprocity are notoriously different; and the one shown by the continuous proportion in the diagram of the Pole includes the second kind. The first is purely external and the second is internal to the order considered.

All the misunderstandings about what is mechanics come from here. And the essential difference between a mechanical system in the trivial sense and an ordered or self-organized system lies precisely at this point.

At the time it was believed that Hertz’s experiments confirmed Maxwell’s equations and disproved Weber’s, but that is another misunderstanding because if Weber’s law —which was the first to introduce the factor of the speed of light- did not predict electromagnetic waves, it did not exclude them either. It simply ignored them. On the other hand, some perceptive observers have noted that the only thing Hertz demonstrated was the reality of the action at a distance, not of waves, but that is another story.

As a counterpoint, it is worth remembering another fact that shows, among other things, that Weber had not fallen behind his time. Between the 1850s and 1870s he developed a stable model of the atom with elliptical orbits —many decades before Bohr proposed his model of the circular atom, without the need to postulate special forces for the nucleus.

Weber’s relational dynamics shows another aspect that may seem exotic in the light of the present theories: according to its equations, when two positive charges approach a critical distance, they produce a net attractive force, rather than a repulsive one. But is not the very idea of an elementary charge exotic in the first place, or should we just say a mere convention? In any case, this fits very well with the Taijitu diagram, in which a polarized force can potentially become its opposite. Without this spontaneous reversal, hardly we could speak of truly alive forces and potentials.

Physics and the continuous proportion

We already see that there are purely mathematical reasons for the continuous proportion to appear in the designs of nature independently of causality, be it physical, chemical or biological: in fact the convenience of logarithmic growth is independent even of the form itself, as is the elementary fact of the discrete and asymmetric division of cells.

In this light, it would be an emergent property, just a parallel plane to physical causation and becoming. On the other hand, the idea of parallel planes with a merely circumstantial connection with physical reality looks odd, and in any case very distant from what the diagram of the Pole express so well —that no form or nothing apparent is free from dynamics.

The fact is that the connection between physics and the continuous proportion is very dim, to say the least. However we have important occurrences of this ratio even in the Solar System, where it is almost impossible to avoid celestial mechanics. A better understanding of the presence of the continuous proportion in nature should not ignore the framework defined by fundamental physical theories, nor what these can leave out.

We have three possible approaches with increasing degrees of risk and depth:

The continuous proportion in nature can be studied independently of the underlying physics as a purely mathematical question; this would be the most prudent, but somewhat limited position. The aforementioned A. Stakhov has developed an algorithmic theory of measurement based on this ratio that can be used to analyze in turn other metrological theories of cycles, continuous fractions and fractals as for example the so called Global Scaling.

This proportion can be studied according with views compatible with known mainstream physics; for example, as Richard Merrick has done, in a neopythagorean rereading of the collective harmonic aspects of wave mechanics, such as resonances, and in which phi would be a critical damping factor [7]. These ideas are totally accessible to the experiment, either in acoustics or in optics, so that they can be verified or falsified.

Merrick’s idea of harmonic interference is within everyone’s reach and understanding and it is not without depth. It can be naturally complemented with the holographic concept proposed by David Bohm and his distinction between the implicate and explicate order. Although Bohm’s interpretation is not standard, it is compatible with experimental data. The harmonic interference theory can also be combined with mathematical theories of cycles and scales such as those mentioned.

Or, finally, one can consider other more classical theories that differ from the mainstream but which may provide deeper insights into the subject. Within this category, there are various degrees of disagreement with the standard theories: from just a wider understanding of thermodynamics, to in-depth revisions of classical mechanics, quantum mechanics and calculus. We could say that this third option is not that speculative, but rather divergent in the spirit and the interpretation.

Here we will focus more on the third level, which may also seem the most problematic. One could ask what is the need to question the best established physical theories in order to find a better ground for the occurrence of a constant that maybe does not require them. Furthermore, the first two levels already offer plenty of room for speculation. But this would be a very superficial way of looking at it.

We cannot delve into the presence of the continuous proportion in a symbol of perfect reciprocity ignoring the question of whether our present theories are the best exponent of continuity, homogeneity or reciprocity —and in fact they are far from it.

POLE OF INSPIRATION – The spark and the thread

Those who like simple problems can try to demonstrate this relationship before moving on. It’s insultingly easy:

φ = 1/φ +1 = φ-1+1 = 1/φ-1

We owe this fortunate discovery to John Arioni. The elementary demonstration, along with other unexpected relationships, is on the site Cut the knot [1]. The number φ is, naturally, the golden ratio (1+√ 5)/2, in decimal figures 1.6180339887…, and φ-1 is the reciprocal, 0.6180339887… . And since its infinite decimal places can be calculated by means of the simplest continuous fraction, here we will also call it the continuous ratio or continuous proportion, because of its unique role as mediator between discrete and continuous aspects of nature and mathematics.

This looks like the typical casual association of recreational math pages. One can get φ in many different ways with circles, but to my knowledge this is by far the most elementary of all, being the radius the unit of reference. In other words, this relation seems too simple and direct not to contain something important. And yet it has only recently been discovered, almost by chance.

John Arioni

Since Euclid and probably much earlier, the entire history of findings on this proportion has been derived from the division of a segment “in the extreme and mean ratio”, and has developed with the construction of squares and rectangles. The most immediate cases involving the circle come from the construction of the pentagon and the pentagram, no doubt known to the Pythagoreans; but one does not need to know anything about mathematics to realize that the relationship contained in this symbol is of a much more fundamental order —just as, from the quantitative point of view, the 2 is closer to 1 than 5, or from the qualitative one, the dyad is closer to the monad than the pentad.

If the circle and its central point are the most general and comprehensive symbol of the monad or unit, we have here the most immediate and revealing proportion of reciprocity, or dynamic symmetry, presented after the division into two parts. The Taijitu has a double function, as a symbol of the supreme Pole, beyond duality, and as a representation of the first great polarity or duality. It is, as it were, halfway between both, and both are linked by a ternary relationship —precisely the continuous proportion.

A relation is the perception of a dual connection, while a proportion implies a third order relationship, a “perception of perception”. Since at least the times of the Kepler’s triangle, we have known that the golden mean articulates and conjugates in itself the three most fundamental means of mathematics: the arithmetic mean, the geometric mean, and the so-called harmonic mean between both.

We could ask ourselves what would have happened if Pythagoras had known about this correlation, which would certainly have exalted Kepler’s imagination as well. It will be said that, like any other counterfactual, there is no point about it. But the question is not as much about the past that might have been as it is about the possible future. Pythagoras could hardly have been as surprised as we are, since he knew nothing about the decimal values of φ or π . Today we know that they are two ratios running to an infinite number of decimal places, and yet they are linked exactly by the most elementary triangular relationship.

Mathematical truth is beyond time, but not its revelation and construction. This allows us to see certain things with the insight of a Geohistory, as it were, in four dimensions. There has been speculation about what would have happened if the Greeks had known and made use of the zero, and whether they might have developed modern calculus. This is very doubtful, since they would have still needed to make a series of great leaps far from their conception of the world, such as the numbering system, the zero and its positional use, the idea of derivative, and so on. The double spirals were a common motif in archaic Greece, and the arithmetical speculations of the Pythagoreans, very similar in nature to those developed by the Chinese over time; but for whatever reason the Greeks did not intertwine the two spirals into one, and, in China itself, a diagram like the one we know today did not came into existence until the end of the Ming dynasty and only after a lengthy evolution.

Which is just another example of how hard is to see the obvious. It’s not so much the thing itself, but the context in which it emerges and in which it fits. Depending on how one looks at it, this can be encouraging or discouraging. In knowledge there is always a high margin to simplify, but as in so many other things, that margin depends to a large extent on knowing how to make it happen.

The Taijitu, the symbol of the supreme Pole, is a circle, a wave and a vortex all in one. Of course, the vortex is reduced to its minimum expression in the form of a double spiral. Characteristically, the Greeks separated their double spirals, and eventually turn them into squares, in the motifs known today as grecas. It is just another expression of their taste for statics, a bent that set the general framework for the reception of the golden mean in mathematics and art, and which has come down to us through the Renaissance.

The series of numbers that approximate infinitely the continuous proportion, known to us as Fibonacci numbers, appeared already long before in the numerical triangles consecrated in India to Mount Meru, “the mountain that surrounds the world”, which is just another designation of the Pole. As it is well known, from this figure, called the Pascal’s triangle in the West, a huge number of combinatory properties, scales and sequences of musical notes are derived.

The polar triangle, known in other cultures as Khayyam’s triangle or Yang Hui’s triangle, is one of those “extraordinarily well connected” mathematical objects: from it one can derive the binomial expansion, the binomial and normal statistical distributions, the sin(x)n+1/x transform of harmonic analysis, the matrix esponential and the exponential function, or the values of the two great gears of calculus, the constants π and e. It is almost incredible that the elemental connection with the Euler number has not been discovered until 2012 by Harlan J. Brothers. Instead of adding up all the figures in each row, one only needs to extract the ratio of ratios for their product; the difference between sums and products is a motif that will emerge several times throughout this article.

The polar triangle looks like an arithmetic and “static” representation, while the Taijitu is like a geometric snapshot of something purely dynamic. However, the rich implications for music of this triangle, partially explored by the work of Ervin Wilson, largely circumvent the separations created by adjectives such as “static” and “dynamic”. In any case, if the staircase of figures deployed in Mount Meru is an infinite progression, when we finally see the lines hidden in the circular diagram of the Pole we immediately know that it is something irreducible —the first offers us its arithmetical deployment and the second its geometric retraction.

The oldest known mention of the triangle, albeit a cryptical one, can be found in the Chandaḥśāstra of Pingala, where Mount Meru is shown as the formal archetype for metric variants in versification. It is also fair to say that the first Chinese author to deal with the polar triangle is not Yang Hui but Jia Xian (ca. 1010-1070), a strict contemporary of the philosopher and cosmologist Zhou Dunyi (1017-1073), the first author who publicized the Taijitu diagram.

Nowadays very few people are aware that both figures are representations of the Pole. It is my conjecture that all the mathematical relationships that can be derived from the polar triangle can also be found in Taijitu, or at least generated from it, although under a very different aspect, and with a certain twist that possibly involves φ. Both would be a dual expression of the same unity. Mathematicians will see what is the point of this.

Between counting and measuring, between arithmetic and geometry, we have the basic areas of algebra and calculus; but there is an overwhelming evidence that the latter branches have developed in one particular direction more than in others —more in decomposition than in composition, more in addition than in multiplication, more in analysis than synthesis. So the study of the relations between this two expressions of the Pole could be full of interesting surprises and basic but not trivial results, and it poses a different orientation for mathematics.

It can be seen that the arithmetic triangle has closed links with fundamental aspects of calculus and the mathematical constant e, while the Taijitu and the constant φ lack in this respect relevant connections —hence the totally marginal character of the continuous proportion in modern science. It has been said that the latter, unlike the intimate connection with change of Euler’s number, is a static relationship. However, its appearance in the extremely dynamic character of the yin-yang symbol already warns us of a general change of context.

For centuries calculus has been dissolving the relationship between geometry and change in favor of algebra and arithmetic, of not so pure numbers. Now we can turn this sandglass upside down observing what happens on the upper bulb, the lower bulb and the neck.

The appearance of the golden mean between the yin and yang in a purely curvilinear fashion not only is not static but on the contrary cannot be more dynamic and functional, and indeed the Taijitu is the most complete expression of activity and dynamism with the minimum number of elements. The diagram also has an intrinsic organic and biological connotation, inevitably evoking cell division, which in fact is an asymmetrical process, and, at least in plant growth, often follows a sequence governed by this ratio. In other words, the context in which the continuous ratio emerges here is the true antithesis of its Greek reception that has lasted until today, and this can have far-reaching implications on our perception of this proportion.

Oleg Bodnar has developed an elegant mathematical model of plant phyllotaxis with hyperbolic golden functions in three dimensions and with coefficients of reciprocal expansion and contraction that can be seen in the great panoramic book that Alexey Stakhov dedicates to the Mathematics of Harmony [2]. It is an example of dynamic symmetry that can be perfectly combined with the great diagram of polarity, regardless of the nature of the underlying physical forces.

The presence of spiral patterns based on the continuous proportion and their numerical series in living beings does not seem mysterious. Whether in the case of a nautilus or vegetable tendrils, the logarithmic spiral —the general case- allows indefinite growth with no change of shape. Spirals and helixes seem an inevitable result of the dynamics of growth, by the constant accretion of material on what is already there. At any rate, we should ask why among all the possible proportions of the logarithmic spiral those close to this constant arise so often.

And the answer would be that the discrete approaches to the continuous proportion also have optimal properties from several points of view —and cell growth ultimately depends on the discrete process of cell division, and at higher levels of organization, on other discrete elements such as tendrils or leaves. Since the convergence of the continuous ratio is the slowest, and plants tend to fill as much room as possible, this ratio allows them to emit the greatest number of leaves in the space available.

This explanation seems, from a descriptive point of view, sufficient, and makes it unnecessary to invoke natural selection or deeper physical mechanisms. However, in addition to the basic discrete-continuos relationship, it contains implicitly a powerful link between forms generated by an axis, such as the pine cones, and the so-called “principle of maximum entropy production” of thermodynamics, which we will find later again.

Needless to say, we do not think this proportion has “the secret” to any universal canon of beauty, since surely such a canon does not even exist. However, its recurrent presence in the patterns of nature shows us different aspects of an spontaneous principle of organization, or self-organization, behind what we superficially call “design”. On the other hand, the appearance of this mathematical constant, due to its very irreducible properties, in a great number of problems of optimization, maximums and minimums, and parameters with critical points allows us to connect it both naturally and functionally with human design and its search for the most efficient and elegant configurations.

The emergence of the continuous proportion in the dynamic symbol of the Pole —of the very principle- augurs a substantive change both in the contemplation of Nature and in the artificial constructions of human beings. Contemplation and construction are antagonistic activities. One goes top-down and the other bottom-up, but there is always some sort of balance between both. Contemplation allows us to free ourselves from the connections already built, and construction gets ready to fill the resulting void with new ones.

It is somewhat strange that the continuous proportion, despite its frequent presence in Nature, is so poorly connected with the two great constants of calculus, π and e —except for anecdotic incidences as the “logarithmic golden spiral”, which is only a particular case of an equiangular spiral. We know that both π and e are transcendental numbers, while φ is not, although it is indeed the “most irrational number”, in the sense that it is the one with the slowest approximation by rational numbers or fractions. φ is also the simplest natural fractal.

Until now, the most direct link with trigonometric series has been through the decagon and the identities φ = 2cos 36° = 2cos (π/5). It has not been associated so far with imaginary numbers, i being the other great constant of calculus, which is concurrent with the other two in Euler’s formula, of which the so-called Euler identity (eiπ = -1) is a particular case.

The number e, base of the function that is its own derivative, appears naturally in rates of change, the subdivisions ad infinitum of a unit that tend to a limit or in wave mechanics. The imaginary numbers, on the other hand, so common in modern physics, appeared for the first time with the cubic equations and pop up each time additional degrees of freedom are assigned to the complex plane.

Actually, complex numbers behave exactly like two-dimensional vectors, in which the real part is the inner or scalar product or and the so-called imaginary part corresponds to the cross or vector product; so imaginary numbers can only be associated with motions, rotations and positions in space in additional dimensions, not with the physical quantities themselves.

This is easier to say than to think of, since it is even more “complex” to determine what a physical quantity or a mathematical variable can be independently of change and motion. Both to geometrically interpret the meaning of vectors and complex numbers in physics and to generalize them to any dimension a tool like geometric algebra may be used —”the algebra flowing from geometry”, as Hestenes put it; but even then there is much more to geometry than we may think.

Many problems become more simple on the complex plane, or so the mathematicians say. One of them, under the pseudonym Agno sent in 2011 an entry to a math forum with the title “Imaginary Golden Mean”, which shows a direct connection with π and e : Φi = e ± πi/3 [3]. Another anonymous author found this same identity in 2016, along with similar derivations, looking for fundamental properties of an operation known as “reciprocal addition”, of interest in circuits and parallel resistances calculations. As refraction is a kind of impedance, it may also have its place in optics. The relation in the polar diagram may be associated right from the start with geometric series and hypergeometric functions associated with continuous fractions, modular forms and Fibonacci series, and even with noncommutative geometry [4]. The imaginary golden ratio, in any case, reflects as in a mirror many of the qualities of its real part.

The Taijitu is a circle, a wave and a vortex all in one. The synthetic genius of nature is quite different from that of man, and she does not ask for unifications because not to arbitrarily separate is enough for her. Nature, as Fresnel said, does not care about analytical difficulties.

The diagram of the Taijitu becomes a flat section of a double spiral expanding and contracting in three dimensions, a motion that seems to give it an “extra dimension” in time. It is always a real challenge to follow the evolution of this process, both spiral and helical, within a vertical cylinder, which is but the complete representation of the indefinite propagation of a wave motion, the “universal spherical vortex” described by René Guenon in three short chapters of his work “The Symbolism of the Cross”. The cross of which Guenon speaks is certainly a system of coordinates in the most metaphysical sense of the word; but the physical side of the subject is by no means negligible.

The propagation of a wave in space is a process as simple as it is difficult to grasp in its entirety; one need only think of Huygens’ principle, the universal mode of propagation, which also underlies all quantum mechanics, and which involves continuous deformation in a homogeneous medium.

In that same year of 1931 when Guenon was writing about the evolution of the universal spherical vortex, the first work was published on what we know today as the Hopf fibration, the map of the connections between a three-dimensional sphere and a sphere in two dimensions. This enormously complex fibration is found even in a simple two-dimensional harmonic oscillator. Also in the same year, Paul Dirac conjectured the existence of that unicorn of modern physics known as the magnetic monopole, which brought the same kind of evolution into the context of quantum electrodynamics.

Peter Alexander Venis gives us in a wonderful work a completely phenomenological approach to the classification and typology of the different vortices. There is nothing mathematical here, neither advanced nor elementary, but a sequence of transformations of 5 + 5 + 2, or 7 classes of vortices with many types and countless variants that unfold from the completely undifferentiated only to return to the undifferentiated again —or to the infinity of which Venis prefers to speak. The transitions from ideal points with no extension to the apparent forms of nature seems quite arbitrary without the aid of vortices, hence their importance and universality.

Peter Alexander Venis

Venis does not deal with the mathematical and physical aspects of such a complex subject as vortices, and of course he does not apply to them the continuous proportion; on the contrary he gives us the privilege of a new fresh vision of these rich processes, in which the insight of a presocratic naturalist and the capacity for synthesis of a Chinese systematist meet together effortlessly.

Even if the Venis sequence admits variations, it presents us a morphological model of evolution that goes beyond the scope of ordinary sciences and disciplines. The author includes under the term “vortices” flow processes that may or may not have rotation, but there is a good reason for that, since this is necessary to cover key conditions of equilibrium. He also applies the theory of yin and yang in a way that is both logical and intuitive, which probably admits a fairly elementary translation to the qualitative principles of other traditions.

The study of this sequence of transformations, in which questions of acoustics and image are closely linked, should be of immediate interest in order to deepen the criteria of morphology and design even without the need to enter into further considerations.

Peter Alexander Venis

A metric-free description would be, precisely, the perfect counterpoint for a subject as badly affected by arbitrariness in the measurement criteria as the study of proportionality. Naturally, mathematics also has several tools essentially free of metrics, such as external differential forms, which allow the study of the physical fields with maximum elegance. Then, perhaps, the metrics that physics deals with could be used as a middle ground between both extremes.

Thus, in this search to better define the context for the appearance of the continuous proportion in the world of phenomena, we can speak of three types of basic spaces: the ametric or metric-free space, the metric spaces, and the parametric or parameter spaces.

By metric-free space we understand the different spaces that are free of metrics and the action of measurement, from the purely morphological sequence of vortices above to projective geometry or the metric independent parts of the topology or differential forms. The projective, metric-independent space is the only true space; if we sometimes speak of metric spaces it is only because of the different connections with metric spaces.

By metric spaces, we mean those of the fundamental theories in physics, not only mainstream theories but also other related, with a special emphasis on Euclidean metric space in three dimensions of our ordinary experience. They include physical constants and variables, but here we are particularly interested in theories that do not depend on dimensional constants and can be expressed in homogeneous proportions or quantities.

By parametric or parameter spaces we mean the spaces of correlations, data, and adjustable values that serve to define mathematical models, with any number of dimensions. We can also call it the algorithmic and statistical sector.

We are not going to deal here with the countless relationships that can exist between these three kinds of spaces. Suffice it to say that to get out of this labyrinth of complexity in which all sciences are already immersed, the only possible Ariadne’s thread, if any, has to trace a retrograde path: from numbers to phenomena, with the emphasis on the latter and not the other way around. And we are referring to phenomena not previously limited by a metric space.

Much has been said about the distinction between “the two cultures” of sciences and the humanities, but it should be noted that, before attempting to close this by now unsurmountable gap, we should begin first by bridging the gap between the natural, descriptive sciences and a physical science that, justified by its predictions, becomes indistinguishable with the power of abstraction of mathematics while isolating itself from the rest of Nature, to which it would like to serve as foundation. Reversing this fatal trend is of the greatest importance for the human being, and all efforts in that direction are worthwhile.
