The founder of LFS (The Finnish Society for Natural Philosophy) professor K.V. Laurikainen held popular seminars in the cellar auditorium of the Department of High Energy Physics on Thursdays in the end of the 70’s. The main topic was quantum mechanics and its interpretations. I recall specifically that ”The Heisenberg uncertainty principle can be interpreted such that (true) reality seems to be covered by a veil, but our physical worldview contains features of reality” (recollection, not a quote). This made me ponder: Do all worldviews contain features of reality? A worldview is observer dependent! What is the worldview like of a being without any senses (mankind always blind, deaf etc.) ? The worldview becomes: ”SOMETHING EXISTS” (fully internal, simplest possible) Alternative: ”NOTHING EXISTS” Let’s name these ”1” and ”0”, and a binary worldview is born, which can be described by integer powers of 2. This worldview should contain features of reality, too! A rather naive and amusing idea!! But it can be tested!! 3Finnish Society for Natural Philosophy,

Let us examine ratios R of commensurate physical quantities x. An integer power of two is the simplest form of the ratio (not any binary number). For the first test I chose two quantities, which have nothing to do with one another: The hydrogen 21 cm wavelength and the Planck length. We obtain The integer exponent 112 was quite a surprise (c. year 1982)! Finnish Society for Natural Philosophy, N=integer

After that I calculated ratios of 49 quantities including rest energies of elementary particles, radii of the orbits of the planets etc. Of course the magnitude of the ratio R depends on what is compared. It turned out that the majority of the ratios were something else than integer powers of two. However, the decimal part of the exponent tells how close the exponent is to an integer value (e.g. exponents and are close to integer 112). Finnish Society for Natural Philosophy, Count N=i.00 N=i.33 N=i.66 The decimal parts seem to form three groups (i depends on the magnitude of R) : Distribution of the decimal parts The exponents are of the form integer/3, i.e. cube roots of an integer power of 2.

The test data included ratios of different quantities (length, temperature, rest energy, wavelength), so the ratio applies to all of these pointing to a common property, which means that the quantities in question can be expressed in terms of the same quantity. All quantities in the test data can be expressed by using period  : Energy : E=hf=h/  Wavelength: =c  (also circumference of an orbit) Temperature T=h/k  Magnetic moment:  =ec 2  /4  What is a period good for? Finnish Society for Natural Philosophy,

Chaos was a very popular research topic in the1980’s. It was theoretically shown that nonlinear dynamical systems develop towards (apparent) chaos via a phenomenon called period doubling. M. J. Feigenbaum (1978, 1980) showed that period doubling is a universal property of nonlinear dynamical systems. Period doubling has been demonstrated in many experiments. If the fundamental period is  o, then the N’th period is Especially stable are periods (i positive integer). The ratio of periods becomes: Finnish Society for Natural Philosophy, (1) (2) (valid for all quantities in question)

The N’th period is(observation) Cubing both sides of (3) yields: Equation (4) means that doubling takes place in the volume of the period-space. Volume means that the system has three 3 internal degrees of freedom (dimensions of the period-space). Finnish Society for Natural Philosophy, (3) (4) n=3N Periods (=edges) have equal number of doublings.

Let us generalize (4) into a ┴ parallelepiped: According to the observation the ratios R are cube roots, and so the perceived period is which can be converted into other quantities, e.g. energy. In this case the system has three internal degrees of freedom, each having the related energy. The cube root (geometric mean of the energies) returns the observed energy (Joule, scalar quantity). Finnish Society for Natural Philosophy, (5) (6) Different number of doublings

The rest energy of the pair is E ep =1.022 MeV. The so called Planck energy E o = MeV can be calculated from h, c and G. Taking this as reference energy one obtains for R: We find that the exponent of 2 is very close to an integer divided by 3. What is 224? Can we break 224 into a sum of integer powers of two? If so, then the system is superstable. One obtains meaning that the structure of the electron-positron pair is superstable (otherwise we would not exist as we are). Eq. (8) yields the ep-pair rest energy with an inaccuracy of one thousandth. Finnish Society for Natural Philosophy, (7) (8)

The electron has a measurable magnetic moment. Magnetic moment µ is defined as a current loop µ=iA, where i is the current and A the area. The Planck loop serves as the natural reference, where the circumference is the Planck length l o =c  o and current the elementary charge divided by the Planck time (period). The reference becomes E-p pair magnetic moment is Am 2, and the ratio R becomes Note the same superstability in the ep-pair rest energy! Eq’s (9) and (10) yield a practically accurate value for the electron magnetic moment (difference is % compared to the NIST value, details in (Lehto 2009)). Finnish Society for Natural Philosophy, (9) (10)

Let us take the Planck charge q o as reference: The ratio of the Coulomb energies (proportional to the square of charge) is The Coulomb energy of the elementary charge has four internal degrees of freedom! The fourth root also brings about the +/- polarity. Is the system superstable? 39 = = Yes it is. The value given by (11) for the elementary charge deviates from the NIST value by % (Lehto 1984). Finnish Society for Natural Philosophy, (10) (11)

Equations for the circumference and orbital speed are (Lehto 1990): Finnish Society for Natural Philosophy, (13) (12) The initial dust and gas accumulate into orbits determined by period doubling (attractors). Note that the orbital velocities of the planets are given by consequent integers M from (13). A more detailed analysis has been carried out (Lehto 2009, 2014).

Both gravitational and Coulomb potentials are 1/r nonlinear. It is possible to derive a differential equation (Lehto 2009) in period-space ( ,r) (compare space-time) : the solutions of which give the 3-d and 4-d period doubling depending on the value of a (for 3-d doubling a=46.5 and 4-d a=82.4). Other superstable systems are: proton (rest energy, charge and magnetic moment) hydrogen 21 cm wavelength system producing the cosmic (microwave) background radiation (CBR, 3K temperature) 3-d period doubling can be observed in the quantized galaxy redshifts (Lehto-Tifft rule, Tifft 1997, 2014). Finnish Society for Natural Philosophy, (14) Note: Equations (12) and (13) explain the Bode-Titius rule.

Finnish Society for Natural Philosophy, A fractal tree is an example of an object, which seems to be very complex at the top. This is an illusion, however, because the structure of the tree results from repeating the same principle. A closer look reveals that the stem and the branches are continuously split into two when going upwards. This phenomenon is called bifurcation, which eventually leads to an apparent chaos. In nonlinear dynamical systems bifurcation means period doubling. Picture (without text): ojure-13-first-impression.html Simple origin Seemingly complex, present time Complexity grows with system evolution Base in this study: The Planck units

Consideration of a possible relation between the simplest worldview and reality led to the discovery of the period doubling phenomenon in several natural systems. period doubling is a universal property of nonlinear dynamical systems (Feigenbaum) it was found out that the systems analyzed have internal degrees of freedom, which form 3-d and 4-d period-spaces. a differential equation for the occurrence of 3-d and 4-d period doubling in 1/r- potential can be derived. the volume of the phase space must be returned to 1-d by taking cube- and fourth roots (e.g. energy: (Joule 3 ) 1/3 →Joule). the analysis shows that the intrinsic properties of the electron and proton are superstable (rest mass, charge, magnetic moment). Longlife (stable) structures evolve by repeating the simple period doubling process starting from the Planck scale (defined by the natural constants). Finnish Society for Natural Philosophy,

Wikipedia: ” Traditionally, metaphysics attempts to answer two basic questions in the broadest possible terms: What is ultimately there? What is it like?”. Pondering the relation between the simplest physical worldview and reality led to the discovery of the period doubling phenomenon in the 1/r- potential systems. This is metaphysics (?). Wikipedia: “Empiricism in the philosophy of science emphasizes evidence, especially as discovered in experiments. It is a fundamental part of the scientific method that all hypotheses and theories must be tested against observations of the natural world rather than resting solely on a priori reasoning, intuition, or revelation.” The discovery of the period doubling phenomenon in the 1/r-potential systems and the related mathematical theory belong to the realm of empiricism.
