Abstract

Low-temperature thermoluminescence has been used in attempt to understand the particular structure of ultra high dilutions. Samples are activated by irradiation after freezing at the temperature of liquid nitrogen (77°K). Experimental results show that, in the course of rewarming, the thermoluminescent glow is susbtantially different between dilutions of different substances. It is suggested that the dispersed gas phase might play a role in this process.

Introduction

No chemical is more common on earth than water: it covers 75% of the earth’s surface with a total mass of 1.4 billion megatons. A very simple molecule, with one central, negatively charged, oxygen atom and two positively charged hydrogen atoms 0.1 nm apart at an angle of 104°1 water is, nevertheless, a most atypical compound. In the liquid state, it is an abnormal fluid which should be a gas by comparison with other similar chemicals. Among other unusual properties, it increases in volume when crystallizing into solid ice at 0°C and boils at 100°C: both these temperatures are abnormally high for a substance which is neither a metal nor an ionic compound. Its dielectric constant as well as its increasing fluidity with rising pressure is equally odd.

In fact, liquid water is not a simple association of independent molecules; the molecules are actively interconnected by hydrogen bonds[2] and [3]. Liquid water is, indeed, a structured fluid which behaves as a polymer. In an ever-moving universe, individual water molecules link to each other, most often in tetrahedral geometry, building evanescent clusters which are continuously formed and dissociated again at random in a pico-second timeframe. When an ionic compound is dissolved in H2O, each ion is immediately surrounded by a spherical shell of water molecules so intensely that, should the concentration of the solute be high enough (over about 10%) all the shells come into contact and there is no more truly liquid water.

It can, thus, be understood that, in the preparation of an homeopathic medicine, any compound dispersed in water gives rise, from the outset, to a specific structure. When successive dilutions are made the violent turbulence created in the liquid by each succussion, helps to both maintain and possibly spread the original structure despite, progressively, the solute content of the dilution dropping by a factor of 100 with each centesimal step. However, Brownian motion is still very active and these ‘remnant structures’ fade away and reconstitute continuously. In other terms, we could say that homeopathic dilutions are ‘statistically structured’ and could remain so beyond the Avogadro number. Succussion appears to be an essential part of the overall process.

Research objective

It is easy to understand why, based upon this succession of dilutions–succussions, many scientists believe that eventually—and definitely beyond the Avogadro number—the resulting ‘solutions’ are no more than the dilution fluid itself. However, numerous physiological and clinical tests have demonstrated for decades, since Hahnemann himself, that this is not the case. Our research objective has been to try to demonstrate that the high dilutions are physically different from the diluent and have, indeed, an ‘individual personality’.

Method

Since any investigation is always difficult in an highly dynamic system we assumed that, should some specific ‘patterns’ exist in the liquid dilution they might be fixed when it is frozen giving rise to specific defects in the crystal lattice of ice, which could be investigated by appropriate means.

To perform this type of studies we selected low-temperature thermoluminescence. This technique, which is well known for archaeological and geological dating,4 has been adapted by us to low temperatures5 and described in detail in previous publications.[6] and [7] I will here only summarize here its main features.

A 1 cc sample of the dilution under investigation is placed in an aluminum cup and frozen down to liquid nitrogen temperature (−196°C=77°K) following a well defined multi-step process. The frozen 1 mm thick ice disk is then ‘activated’ by radiation (Gamma rays, X-rays or electron beams) which displace electrons from their quantum ground states. The sample is then rewarmed at constant rate (3°C/min) from 77°K to melting point. During that process the electrons, powered by ‘thermal activation’ leave their respective traps and recombine with the empty quantum ‘holes’ releasing their ‘activation energy’ in the form of light as they do so. This light is the thermoluminescent glow that we record.

The analysis of the emitted light shows two main peaks around 120 and 166°K for deuterium oxide and 115 and 162°K for H2O.5 Their relative intensity and shape vary both with the radiation dose and also with the nature of the radiant beam. In particular peak 2 displays a complex structure which can be resolved in a set of individual components by a deconvolution technique.[8] and [9] It is assumed that the ‘defects’ present in the ice crystalline lattice are active luminescent centers, hence that thermoluminescence might be an appropriate tool to study the ‘image’ of the initial liquid samples.

Results

Thermoluminescence is known to be a very sensitive technique and has been used to identify trace compounds. For example see Figure 1, the thermoluminescence emissions of very dilute alumina colloidal sols which show major differences between the 10−8 g/ml, 10−9 and 10−10 g/ml solutions.

For homeopathic high dilutions we use deuterium oxide (D2O, heavy water) as the solute since the signal is 50 times more intense than that of H2O, due to the more rigid nature of the two ‘arms’ of the molecule. As diluted substances we selected two ionic compounds: sodium chloride (NaCl) and lithium chloride (LiCl). The latter was selected because, like urea and ethanol, it is known to impact on and suppress the hydrogen bonds10 which are thought to be involved into the high temperature peak (ca 166°K) of the thermoluminescence glow.6 Figure 2 shows that the curves recorded for successive dilutions of LiCl (3c, 5c, 7c, 9c) prepared by the classical Hahnemannian method and following the French Homeopathic Pharmacopoeia (150 strokes of 2 cm amplitude in 7.5 s, delivered by mechanical succussion machine) are substantially different.

Subsequently, since it appeared that we had a reliable tool for assessing the dilutions we applied the same method to ultra-high dilutions beyond Avogadro’s number.6 Figure 3 gives the results and shows evidence that the ‘signature’ peak of LiCl 15c is substantially lower than that of NaCl 15c and lower than succussed pure D2O. This demonstrates that: ultra-high dilutions are different from their dilution fluid.

The high temperature components of the glow (ca 166°K) is linked to the hydrogen bond network. These results have been recently confirmed by another research group.11

In recent and still unpublished experiments we found the same type of ‘scaling’ between increasing dilutions of other compounds, among which potassium dichromate looks particularly interesting.12

New prospects

As I said above, in the homeopathic preparation scheme, succussion is an important component of the preparation process of homeopathic medicines, releasing considerable energy in the fluid. In view of this I became interested in recent research on the role of ‘nanobubbles’ in water.13 Part of the ‘message’ transferred from one dilution step to the next one might be linked to the nanobubbles created into the liquid by the successive strong mechanical agitation which creates turbulence.

To investigate this, we built special equipment to perform dynamization in gas atmosphere or vacuum. We dynamize the dilution at room temperature (20°C) under a moderate vacuum (2337 Pa=24 mbar) which corresponds to the saturated water vapour pressure at 20°C. Time to reach vacuum is approximately 20 seconds. Dynamization is 150 strokes in 7.5 sec followed by stabilization under reduced pressure for 3 minute. The vacuum is broken reverting to atmospheric pressure in 20 seconds. Figure 4 gives preliminary results which show that the gas-phase seems to play a major role in the ‘personalization’ of the dilutions. Bearing in mind that the number of nanobubbles created into the fluid is of the order of billions (which represents a very large ‘contact’ surface with the surrounding liquid) and that, due to their size, they may remain stable and undisturbed in the dilution for months or even much longer, this might open some new perspectives on our understanding of the homeopathic preparation process.

We dynamize the dilution at room temperature (20°C) under moderate vacuum (2337 Pa=24 mbar) which corresponds to the saturated water vapour pressure at 20°C. The time to reach vacuum is approximately 20 seconds, we use our standard dynamization: 150 strokes of approximately 2 cm amplitude in 7.5 sec, followed by stabilization under reduced pressure for 3 minutes. The vacuum is then broken, reverting to atmospheric pressure in approximately 20 seconds.

Abstract

The key stumbling block to serious consideration of homeopathy is the presumed “implausibility” of biological activity for homeopathic medicines in which the source material is diluted past Avogadro’s number of molecules. Such an argument relies heavily on the assumptions of elementary chemistry (and biochemistry), in which the material composition of a solution, (dilution factors and ligand–receptor interactions), is the essential consideration.

In contrast, materials science focuses on the three-dimensional complex network structure of the condensed phase of water itself, rather than the original solute molecules. The nanoheterogenous structure of water can be determined by interactive phenomena such as epitaxy (the transmission of structural information from the surface of one material to another without the transfer of any matter), temperature–pressure processes during succussion, and formation of colloidal nanobubbles containing gaseous inclusions of oxygen, nitrogen, carbon dioxide, and possibly the remedy source material.

Preliminary data obtained using Raman and Ultra-Violet–Visible (UV–VIS) spectroscopy illustrate the ability to distinguish two different homeopathic medicines (Nux vomica and Natrum muriaticum) from one another and to differentiate, within a given medicine, the 6c, 12c, and 30c potencies. Materials science concepts and experimental tools offer a new approach to contemporary science, for making significant advances in the basic science studies of homeopathic medicines.

Introduction

Overview

The key stumbling block to serious consideration of homeopathy is the alleged “implausibility” of biological activity for homeopathic medicines in which the source material is diluted past Avogadro’s number of molecules (6×1023), because the remedy must be identical to the solvent. Negative studies of homeopathy are self-evidently correct from the skeptics’ perspective, because of this error.1 The implausibility argument leads skeptics to ignore or reject positive evidence from numerous basic science, preclinical, and clinical studies showing effects of homeopathic medicines different from controls, in vitro and in living systems.2 On the other hand, proponents predictably reject the negative and focus on positive studies, often uncertain how to address the black box nature of homeopathic medicines. Both skeptics and proponents of homeopathy have generally overlooked a large body of literature in the materials science field that could help resolve this impasse with systematic data.3

Thoroughly, established materials science concepts and research data render the implausibility hypothesis for homeopathy irrelevant. One example suffices. Diamond is the hardest material in nature and graphite among the softest. Yet they can be inter-converted with zero change of composition in microseconds.

The available studies enable significant hypothesis-driven advances in the rigorous study of the nature of homeopathic medicines. The purpose of this paper is to outline the key aspects of materials science considerations in developing experimental models for understanding homeopathic medicines and to summarize preliminary findings from hypothesis-driven studies in our laboratory on clinically known polychrests such as Nux vomica (Nux vom) and Natrum muriaticum (Nat mur).

Materials Science Models for homeopathic medicine

Chemists and medical scientists largely continue to focus reductionistically on the presence or absence of specific molecular species present in water vapor or liquid water without consideration of the ways in which these species are organized in space. From a chemical perspective, the dilution aspects of remedy preparation are the key issue, because of a lack of source molecules for potencies at or beyond 12c or 24c× (10−24 dilution). Even when chemists focus on water itself, they emphasize the fleeting stability of hydrogen bonding between given water molecules,4 rather than the larger complex structural formations of water or the weaker forces that may favor formation of stable oligomeric and polymeric structures, involving the collective organization of many different water molecules within the condensed liquid phase.

In contrast, materials scientists focus on the organizational network arrangement of the water structures in three-dimensional (3-D) space. In a recent paper, Roy et al.3 presented the detailed technical aspects of the materials science argument concerning ultradilute sols including homeopathic medicines at length. For materials scientists, the succussion aspects of remedy preparation are the key consideration. Temperature and pressure can modify such water structures, leading to nanoheterogeneity of larger structures of water molecule “clusters” within liquid water. Succussion introduces intense turbulence and changes in pressure in any solution,5 as well as leading to the formation of nanobubbles in solution.

In brief, the plausibility argument for homeopathy is that liquid water, the primary solvent for source materials in which homeopathic medicines are made, is itself an anomalous substance and has many very different structures. As part of the natural nanoheterogeneity of water structure per se (as contrasted with its composition or the presence of solute molecules), processes such as epitaxy, pressure changes during succussion, formation of colloidal nanobubbles containing gaseous inclusions of oxygen, nitrogen, carbon dioxide, and possibly the remedy source material, and electromagnetic field effects play a role in altering water structure. Previous work by Elia and Niccoli6 and Rey,7 using different technical methods, respectively, to release heat or light from homeopathic medicines in potency, point to the ability to disrupt what appears to be order or structure in remedy solutions as compared with remedy-free control solvents.

In terms of nanoheterogeneity, water can take on many possible oligomeric and polymeric structures, ie, form complex networks of water molecules in 3-D space, held together by various forces that include not only hydrogen bonds (relatively strong), but also van der Waals forces (much weaker). Even if specific molecules or small molecular complexes leave their places in the network, other water structure complexes can take their places within the network structure itself, thereby maintaining the overall nanostructures within the solution, in part via configurational entropy or electromagnetic forces maintaining organizational stability of the network.8

Notably, research in the field of complex systems and network science has shown that, within a highly complex network, loss or disruption of a given member or node, which is a point of interconnection with other members of the network (eg. a water molecule or small complex of water molecules) does not destroy or significantly disrupt the overall network organization.[9] and [10] With complexity in liquid water as a whole comes the capacity for overall stability that is not possible in the simpler organizational structures of water on which chemists usually focus.

Epitaxy is the transfer of information, not material, from the surface of one material, usually solid, to another, usually liquid11. The substrate (eg. remedy source material) acts as a seed crystal for the formation of the structure in the recipient surface material (eg. network organization of water structures). Semi-conductor manufacturing often utilizes epitaxial growth to generate specific types of microtransistors and integrated circuitry. In addition to the original source material that uniquely contributes to remedy preparation, deliberate additives in homeopathic medicines, such as ethanol, and/or possible contaminants from succussion, such as silicates from glass container walls, may also stabilize the water molecule structures with their own epitaxial capabilities. Thus, epitaxy can interact with temperature–pressure factors to create unique patterns of information without the transfer of material.

In terms of “seeding” formation of informational structures within water, initial empirical observations on homeopathic medicines suggest that the passage of time between the original remedy preparation and the testing procedures can alter experimental findings. In calorimetric and thermoluminescence studies on homeopathic medicines, the time factor contributes to differences in the magnitude and even the direction of the divergence between remedy and control solutions.[4] and [12] Overall, the behavior of homeopathic medicine liquids in terms of their structural properties in the basic science literature exhibits a somewhat unpredictable, self-organizing quality.

As additional data emerge, these lines of research may facilitate advances in understanding the nature and mechanisms of variability in clinical responsivity to homeopathic medicines.[13] and [14] Water is an hub molecule (a highly interconnected and influential molecule) in most of the biochemical reactions in the body.15 In a more speculative but testable vein, seeding informational changes in body water at global and local levels16 of scale could be one way in which homeopathic medicines interface with patients to induce patterns of system-wide and local healing responses.13

Implications of materials science models for basic science research methods in homeopathy

Materials science models for the nature of homeopathic medicines leads to more rational selection of specific methodologies for basic science studies. For example, many earlier studies of homeopathic medicines relied on nuclear magnetic resonance (NMR) techniques.[17] and [18] However, NMR spectroscopy provides information on structure of individual atoms in a pure molecule better than on complex networks of molecules. Technically, NMR also requires addition of substances to prepare a liquid for testing. The necessity of adding factors in the process of making observations can introduce unintended contaminants into the measurement process.

In contrast, the light scattering technologies of Raman spectroscopy and Fourier transform (FT) infra-red (IR) spectroscopy permit examination of remedy samples without fixatives or other potential contaminants. Furthermore, Raman and infra-red spectroscopic techniques allow the co-operative nature of structural differences to be detected. Recent studies19 of microscopic dynamics of hydrogen bonded liquids indicate the existence of highly directional H-bonds, whose energy value normally range between not, vert, similar8 and 25 kJ mol−1 induces different chemical–physical properties and different local environments. As the mean lifetime of H-bonds is in the picosecond timescale, such structures are considered as transient species in dynamic equilibrium.

Our recent work has established the importance of the structure of water on its properties,3 we examined the structures of many water and alcohol-based homeopathic remedies. The results show that such materials can be easily distinguished from the pure solvent, and from each other, by the use of UV–VIS (ultraviolet–visual) and Raman spectroscopy, but Fourier transformed infra red (FTIR) spectroscopy proved insensitive to these differences. This opens up a whole new field of endeavor for inorganic materials scientists interested in developing a scientific basis for the efficacy of homeopathic remedies. The assumption of this study is that the joint employment of the two methodologies: optical spectroscopic tools and electronic microscopic tools can furnish a closer reference picture for the comprehension of the structural changes in the liquid phase besides providing an independent understanding on the role of the ‘active ingredient’ in a homeopathic medicine.

Also we believe that our very preliminary efforts in using cryo-scanning electron microscopy (cryo-SEM) and cryo-transmission electron microscopy (cryo-TEM) may eventually possibly provide definitive evidence of the presence, and the effects, of nanobubbles on homeopathic medicine studies.

Preliminary studies of homeopathic medicines using Raman and infrared spectroscopy

Method

A Food and Drug Administration-regulated homeopathic pharmacy (Hahnemann Laboratories, San Rafel, CA) prepared samples of two different test solutions in 16 ounce (450g), clear glass bottles [Type I borosilicate glass] previously annealed at temperatures between 600–700 °C for 15 minutes. One of the solutions, Nat mur (mineral: Sodium Chloride) and the other Nux vom (plant remedy, purchased as tincture from Boiron) were diluted by the standard Hahnemannian techniques in 95% ethanol and succussed: a 30c potency is diluted (1/100)30 or 10−60 from the original material. They were hand-succussed by trained experts [www.hahnemannlabs.com/preparation.html] 30×20=600 times during the manufacturing process. Each bottle was coded with an unique number, the bottles were shipped together by overnight courier in the same box, with temperature sensor.

We have used UV–VIS, IR, FTIR, and Raman spectroscopy for the bulk “liquid” which in most cases is either water or a mixture of water and ethanol (95% ethanol). UV–VIS spectroscopy and Raman spectroscopy proved to be useful tools to investigate the subtle but significant changes in the structural parameters in both water and alcohol based remedies. (For details refer to 20). While other techniques such as freezing point depression; acoustic loss spectroscopy, ellipsometry, viscosity, surface tension, have been explored and will eventually be used in depth to measure entirely different properties, we report here our experience with the major spectroscopic techniques which are widely available.

(b) FTIR spectrophotometer: Thermo Nicolet, Model NEXUS 670, run in attenuated total reflection (ATR) mode, and
(c) Raman spectrophotometer: Inphotonics, Model RS2000-3b-785, using an InPhotonics fiber optic immersion probe.

Results

Nearly 200 runs were made to calibrate every step in the experimental configurations and procedures used for the different instruments. In the dual beam UV–VIS, the many experimental options are all tested separately to ensure that any differences within the data obtained on our samples are well above the instrument noise measured in the calibration run data. The data are obtained largely at different times scales by different individuals gave consistent results. We note that at very low signal levels, instrument noise coupled with artificial computer generated sensitivity can produce data that are not reliable. Hence, we operate the instruments in the sensitivity ranges in which we sacrifice some precision for reproducibility. In the Raman spectrometer, careful attention is paid to the positioning of the probe within the sample container, and stray light is eliminated by turning off all the room lights whenever data are being collected. Details of this work are published elsewhere.21

One of the objectives in undertaking this work is to examine evidence which would suggest reliability of physical properties, assuming structural changes in solvents, especially in ultradilute and dilute sols, an excellent example of the class of materials being homeopathic remedies. For our study, we chose to study Natrum muriaticum and Nux vomica, obtained from Hahnemann Laboratories. Both Nat mur and Nux vom are prepared in 95% ethanol. Three types of analyses are presented:

(a) Comparison of specific homeopathic remedies with different potencies [Nat mur 6c, 12c, 30c, and Nux vom 6c, 12c, 30c].
(b) Comparison between two different remedies of the same potency [Nat mur vs Nux vom 6c, 12c, and 30c].
(c) Comparison of the two homeopathic remedies with unsuccussed and succussed plain ethanol.

Figure 1 shows a comparison of Nux vom and Nat mur, 6c, 12c and 30c, showing representative UV-spectra demonstrating the differences between the remedies. In Figure 2 (a), and (b) we show the envelope of differences within a series of 10 preparations of each remedy of Nat mur and Nux vom. The spectra show clear differences in the same potency of an individual remedy for both Nat mur and Nux vom.

A comparison was also made between the unsuccussed ethanol and the Nat mur and Nux vom samples as shown in Figure 3. The Roy et al paper3, on “structure of water” clearly evidence the role of succussion besides epitaxy and other temperature effects, on the structure of liquids. Under the “normal” succussing procedures, it can be argued that very considerable pressures (of the order of 10 kbar) could be generated as a result of the shaking. Dachille and Roy22 showed that mere grinding in a mortar and pestle gives rise to high pressures up to 20 kbar, and the figures for force per unit area are strongly dependent on the size of the water particles and the velocity of the shaking. By analogy with similar liquids, such as ethanol, there will be many different structures of water formed both by the pressures generated in succussing in some combination with the epitaxy on any additives.

It may be noted from Figure 3 that the absorption spectra for unsuccussed ethanol is significantly different from: (a) the succussed ethanol and (b) succussed homeopathic remedies, Nat mur and Nux vom. The difference may be attributed to the variation in intra and inter-molecular association of ethanol and water and the generation of both transient and stable nanobubbles. The work of Tyrrell and Attard at Australian National University has proved beyond any doubt that nanobubbles do exist and persist.23 FTIR Spectra (not shown here) from all the samples of Nat mur and Nux vom overlap neatly, clearly signifying that FTIR is not the most sensitive technique for analyzing the subtle structural differences in these types of samples.

Comparison of homeopathic remedies with different potencies using Raman spectroscopy is done on the two sets of homeopathic remedies: Nat mur and Nux vom. From the spectra shown in Figure 4, a clear distinction in the Raman active modes is noted between the two different remedies as well as among the different potencies of the same remedy. A clear distinction is shown in the spectral peaks from the different potencies, peak positions identified as (a), (b), (c), (d) and (e) in the Raman spectra of Nat mur samples show significant structural changes. While the existence of distinct structural changes in Nat mur and Nux vom remedies is clear from the Raman spectra, significant structural changes are also noted in the spectra of Nux vom between the different potencies, 6, 12 and 30c, peak positions are identified as (a), (b), (c), and (d) in Figure 4b. Further, since all the homeopathic medicines were prepared in 95% ethanol, we analyzed the Raman spectra of unsuccussed and succussed ethanol shown in Figure 5.

Conclusions

Materials science provides a conceptual and empirical foundation for future research on the nature of all the dilute sols including homeopathic medicines in the physical plane. Processes such as epitaxy, temperature-pressure induced changes in water structure, and nanobubble formation offer testable hypotheses for understanding homeopathic medicines. Although hypotheses regarding seemingly unmeasurable “subtle energies”24 and/or macro-entanglement phenomena[25] and [26] may help explain the fuller nature of homeopathic medicines, the available evidence also suggests that homeopathic medicines can exhibit qualitatively and quantitatively different structural properties from those of unsuccussed or succussed solvents. Even in the case of subtle energies, initial findings indicate the possibility of measuring changes in liquid structure properties from the materials science perspective.[27] and [28]

The convergence of data from different experimental models suggests that it is feasible to study the nature of homeopathic medicines using available basic science tools, notably here, Raman spectroscopy and ultraviolet–visual absorption (UV–VIS) spectroscopy. Reproducibility of findings is feasible within the same Raman equipment, but, not across different Raman spectrophotometers from the same manufacturer at different geographic locations, even for materials other than homeopathic medicines. Fourier transform infrared (FT-IR) spectroscopy cannot differentiate different homeopathic medicines or different potencies of the same remedy from one another. Transmission and structural electron microscopy are promising options for testing the nanobubble hypothesis.

Finally, the materials science perspective provides a possible translational bridge from the emerging complex systems/network science models for clinical responses to homeopathic treatment[5], [12], [13], [29], [30], [31] and [32] to another level of organizational scale, ie, the network structure of the homeopathic medicines themselves. Given the holistic quality of clinical diagnosis and remedy selection in homeopathy, the articulation of holistic (complex network) rather than reductionistic models for both the clinical healing process and the nature of homeopathic medicines is heuristically appealing.

We discovered a previously unknown phenomenon in liquid water, which develops over time when water is left to stand undisturbed, and which made precise gravimetric measurement impossible. We term this property autothixotropy (weak gel-like behaviour developing spontaneously over time) and propose a possible explanation.

The results of quantitative measurements, performed by two different methods, are presented. We also report the newly discovered phenomenon of autothixotropy-hysteresis and describe the dependence of autothixotropy on the degree of molecular translative freedom. A very important conclusion is that the presence of very low concentration of salt ions, these phenomena do not occur in deionized water. Salt ions may be the determinative condition for the occurrence of the phenomena.

‘Autothixotropy’ of water

Qualitative laboratory observations

From 1978 to 1986 we performed a series of measurements[1] and [2] to verify the gravitational law in fluids as deduced by Horák.3 Originally, in 1978 we observed a peculiar phenomenon in the measurements which compelled us to use another method. A series of experiments focusing on this phenomenon were conducted. In the Department of Physics in University of Hradec Králové, an experimental apparatus was constructed (Figure 1) to observe the phenomenon.4

Figure 1. Experimental setup for the static method of measurement.

After objects immersed in the water have been at rest for one or more days, seven qualitatively different phenomena are observed, using this method:

(1) When the hanger is rotated by a certain angle, the plate immersed in the water remains in practically the same position, in spite of the twisting tension arising in the thin filament. When a certain critical angle is reached, the plate will rotate, relatively quickly, to a new neutral position determined by the hanger, to the position where the filament is relaxed (ie with no torsion). If the rotation of the hanger is interrupted before the critical angle is reached, a ‘creep’ toward a new neutral position is observed over some days or weeks. When a smooth-surfaced cylinder, capable of rotating around its own axis, is used instead of the plate, these phenomena are not observed.
(2) Another, weaker phenomenon, is also observed: an immediate rotation of the plate in the direction of the rotation of the hanger; nevertheless, the angle of the immediate rotation is one or two orders of magnitude less than the angle in phenomenon (1).
(3) The critical angle of rotation in phenomenon (1) is dependent on the period of time the water has been at rest. This angle increases with time, starting from virtually zero. (The critical angle can reach values of several tens of degrees)
(4) If the plate is only partially immersed, the critical angle is significantly greater than when it is immersed completely.
(5) In the case of partial immersion, the phenomenon analogous to (2) is much more prominent. Phenomena (4) and (5) are time-dependent as described in (3) despite the time-invariance of the surface tension which we also tested.
(6) If the water is stirred after having been at rest for several days, then, when again at rest, the critical angle increases from zero more quickly than when new ‘fresh’ water is used.
(7) The critical angle is significantly increased and the phenomenon appears earlier if the (distilled) water is boiled (thus substantially deaerated) before the experiment is started.

Our first attempts to carry out quantitative experiments with any acceptable precision were not successful. This was due to a too large dispersion of the measured values; much more sophisticated laboratory equipment than we could acquire, as well as stricter measurement conditions than those we could guarantee, were necessary. In spite of many problems, such experiments have since been performed,5 and showed that the phenomena did not appear in deionized water. In accordance with the generally accepted terminology, we named this complex of phenomena autothixotropy of water.

Proposed explanation

In terms of explanation, a hypothesis based on ‘ephemeral polymerisation’ of water seems plausible. The existence of such a weak polymerisation was suspected decades ago, both defended and denied by experts. If ephemeral polymerisation of water is the cause of the observed phenomena, it suggests that water molecules are establishing chains or a network; first as minute complexes and thereafter combining successively with one another. The structure then becomes increasingly dense while oscillating at a certain amplitude on a scale of molecules. Such a structure will be relatively fragile, susceptible to differences in the concentration of materials dissolved in water, at different points inside the vessel. Brownian motion can be observed in the case of a conglomerate of molecules having a non-polar character, owing to collisions with molecules of water oscillating in the established network. Weak stirring of ‘old’ water seems to leave parts of the network intact, making the subsequent ‘dipole polymerisation’ quicker than it would be in the ‘fresh’ (ie well stirred) water. Further, the structure has some elasticity. If the water is boiled, no dissolved air (gases) disturb either on the developing process or integrity of the structures; consequently, the phenomenon appears earlier and is more pronounced.

One can expect that the described water structure can be important in biophysics for description and influence on cell characteristics (see eg Pollack6). Our observations are consistent with the recently published results of Wernet et al.7

Autothixotropy and molecular translative freedom

The autothixotropy of water depends, among other things, on the degree of freedom of the translative motion of its molecules. The freedom is limited close to the boundary between the water and some other environment, eg a solid body or the atmosphere over the surface of the water. The freedom of the molecular motion is then limited relatively very deep into the body of the water, perhaps on the scale of several hundred molecular layers or more. The limited degree of freedom, depending on the number of free space-dimensions being less than three, appears as follows:

(1) When the free motion is limited to two space-dimensions ie more or less to a plane, one can find its relevant manifestation in phenomena (4) and (5) described above.
(2) If a thin capillary tube were used, the free molecular transitive motion would be limited in practice to just one dimension. This explains the phenomenon of polywater, observed decades ago, and claimed to be a sensational discovery, but which soon proved to be false.
(3) When the transitive freedom is limited in all possible directions, ie in all three space-dimensions, the manifestation of the autothixotropy must logically become very prominent and influential. Such a situation occurs in small cellular spaces and possibly significantly influences, or even determines, the rigidity of the cytoskeleton. It is presumed, however, that the cells aresufficiently static in relevance to the autothixotropy.

Salt ions

Currently two diametrically sets different of results supported by serious observations exist concerning the duration of structures in liquid water. According to one8, molecular clusters in water have a duration of less than one hundred femtoseconds. According to ours, clusters grow to webs on a time scale of days. Since these webs do not arise in deionized water, we believe the purity of the water to be a decisive factor. The distilled water we used was not perfectly pure and could have been significantly contaminated by salt ions, even if only to a very minute degree. From a comparison of experiments with distilled water and deionized distilled water, it is possible to deduce that cores of macroscopic clusters of water molecules are salt ions contained in water.

Moral: If two different observations seem to be mutually incompatible within the frame of an established theory, the most probable explanation is not that one of the observations is wrong, but that the theory is wrong or at least incomplete, and that the observations merely discovered that it was not self-consisrent.

Quantitative experiments on autothixotropy and its hysteresis

Two different, independent strategies were used for quantitative experimental research on the autothixotropy of the water:

1. The static method of torsion.
2. Two dynamic methods: the method of torsion oscillations and the method of small balls falling in water under condition of laminar flow.

The results have been published by Vybíral,[5] and [9] and are summarised below. Static torsion method

Principle

A stainless steel plate is suspended on an elastic filament of torsional rigidity kτ, and immersed in the studied water (Figure 1). The water is in a steady state and the ideal fluid model is assumed. Thus, if we twist the upper end of the filament by angle φu, we expect that the plate will follow the rotation, so that φdu, φd being angle of rotation of the plate. According to our experiments, this equality was not achieved. In the static experiment, a series of increasing values of angle φd is observed, following a very slow, ‘step by step’, change of angle φu. One can specify the moment of force Mw, arising when the plate influences the water: Mw=kτ (φuφd). If angle φu reaches a critical value (φu)crit., the rotation of the plate (ie Click to view the MathML source) becomes quick.

Experimental device

The equipment that was used for the experiment is illustrated in Figure 1. The phosphor–bronze filament had a length L=465 mm and a cross-section of 0.20×0.025 mm2. The torsional rigidity of the filament was determined experimentally from torsion oscillations of the plate hung in non-perturbed air:5 kτ=(1.01±0.02)×10−7 Nm/rad. After reduction to the unit length (1 m), we get kτ1=(4.69±0.07)×10−8 Nm2/rad. The results shown here are related to an experiment with a flat stainless steel plate of width b=38.5 mm, height h=60.5 mm, thickness 0.50 mm and mass 8.50 g. Angles φu and φd were read with an accuracy of not, vert, similar0.5°. Water used for the experiment was distilled and then boiled for 3 min before the experiment began. In the course of the experiment, the temperature of the water was kept between 24 and 25 °C. Water with volume of approx. 350 ml was in a glass vessel with an inner diameter of 80 mm and a height of 110 mm. The vessel was closed with a paper lid with a small opening for the filament. The lid was removed only briefly to read the scale.

Quantitative experimental results

Measurements of the critical angle (φu)crit.

The critical angle is the angle φu at which, when reached by the hanger the plate began to rotate (relatively quickly, in a time scale of tens of seconds) in the same direction. Some prominent results of repeated measurements5 are:

1. The plate immersed with 65% of its surface in water, which had been standing for seven days: (φu)crit.=(398±3)°.
2. With the water boiled for a short time, but otherwise the same configuration of system (immersion 65%). After cooling (not, vert, similar24 °C): (φu)crit. ≈ 30°, after two days: (φu)crit.≈115°.
3. With the water boiled, the plate entirely immersed (the upper edge 10 mm below water level), the critical angle measured on the second and third day was (φu)crit.=(356±3)°.
4. The plate immersed only 50%: (φu)crit.=(343±8)°.
5. The influence of plate immersion on the critical angle (φu)crit. is small: for plate immersion in the range 100–23%, the difference is Δ(φu)crit.≈ 14%.
6. The period of a water-standing influences the magnitude of the critical angle. For example, with immersion of 85% of the surface of the plate and a long period of standing (17 days), we observed (φu)crit.=1800°. As a consequence of the ‘rupture’ which followed, the plate rotated through the angular interval Δφd=1430°. With total immersion such a great critical angle was never reached.
7. After stabilization of the position of the plate (ie, Δφd=1430°), a slow change of angle φd (‘creep’) was observed: 4° in 5 min and, another 32°, in the subsequent 70 hours.

Reproducibility

The results for a given configuration of the measurement system have good reproducibility. For example, if the water was boiled and stood for 24 h, with the plate totally immersed in water for 14 days, six measurements of angle φd were performed. For the same set of angles φu : 60°, 120°, and 180°, the measured respective average angles φd were: (19.6±0.7)°, (34.4±0.6)°, (52.3±1.3)°. When (φu)crit.=(239±2)° was reached, the plate quickly rotated (tens of seconds) and reached a new equilibrium position (φd)0=(198±2)°.

Hysteresis

Hysteresis means that a system does not instantly follow forces applied to it, but reacts slowly or does not return completely to its original state: its state depends on its history. Measurements for a cyclical change of angle φu were carried out. The results of three measurements are shown in Figure 2 and Figure 3. Figure 2 shows the results for the plate entirely immersed in the water which was thoroughly stirred 17 h before. While changing angle φu from the starting equilibrium position φu=φd=0°, the change of angle φd did not follow an ideal straight line φu=φd, but the curve OA. At point A the critical value (φu)crit.1 was reached and then the plate rotated to a new equilibrium position—point B. With decreasing angle φu, angle φd changed according to curve BC, until it reached the second critical value, denoted (φu)crit.2, then the plate rotated to another equilibrium position—point D. When angle φu was decreased again, the position of the plate went through the origin O to the third critical position—point E, with the third critical value, denoted (φu)crit.3. Another equilibrium position corresponded to point F and the fourth critical position corresponded to point G, where (φu)crit.4congruent with(φu)crit.2. As the plate rotated further, a fourth equilibrium position point H, approximately identical with point D, was reached. From there, with decreasing angle φu, the position of the plate followed the previous section HO and for φu=0° it returned to the original equilibrium position φdcongruent with0°.

Figure 3. Results of two experiments (loops of the changes of angle φd=f (φu)): with the completely immersed plate (loop a) and with half-immersed plate (loop b).

In Figure 3, the results of two other experiments with water standing for one week are presented: Loop a refers to experiment with the plate totally immersed, loop b to the experiment with the plate half-immersed; the effect is more pronounced for the half-immersed plate. The loops in Figure 3 are simpler than those in Figure 2 and the respective values (φu)crit. are lower. This can be explained on the microscopic level: The plate probably deformed clusters of water molecules of various dimensions and rigidity.

These experiments suggest that the mechanical properties of clusters of water molecules display hysteresis. The hysteresis is however limited; in our experiment, for instance it does not appear in situations when the critical angle is not reached. For example, if a position of the plate corresponds to a point in the section OA of the graph in Figure 2, before point A is reached, and if we begin to decrease angle φu, the character of the change of angle φd will follow the same curve OA backwards. In these situations, the cluster seems to behave like an ideal elastic body. The dynamics of the phenomenon are similar to those of synovial fluid lubricating the joints of section, which is determined by the thixotropy of the hyaluronic acid present.

Additional measurements

During the experiment, some additional measurements were made to eliminate possible influences on the observed phenomena:

1. The pH of the sample of water was determined by potentiometric measurement. It did not change significantly over a long period; in the range of temperature from 24 to 25°C the pH moved in the range 7.1–6.9.
2. The electrical conductivity of entirely fresh water was 5.6 μS/cm, and after five weeks it increased to 30.5 μS/cm at 25 °C. A dependence of the observed water properties on this change was not noted.
3. Surface tension: Using a Du-Noüyho apparatus (with an accuracy of not, vert, similar1%), no measurable change of the surface tension was found.

Experiments with deionized water

In the second phase of these experiments, water, which was first distilled and then deionized, was used. These experiments showed that in deionized water the phenomenon of autothixotropy and its hysteresis was absent. The same equipment (Figure 1) was used for the experiment and the plate was immersed both to one half and entirely as well. The water stood for 10 days before the measurement. The rotation angle φd of the plate, which passed through the interval φdset membership, variant(0°, 360°, 0°), was equal to angle of torsion φu of the upper end of the filament, with accuracy of not, vert, similar1.5°, as evaluated from the repeated measurements. Neither the existence of critical angles (φu)crit., nor the phenomenon of hysteresis, were found. From this experiment, we arrived at the important conclusion that the autothixotropy of water, characterized by a non-zero critical angle and hysteresis is caused by the presence of ions in the water.5

Method of torsion oscillation

Principle

A plate hangs on a filament (with torsional rigidity kτ) with their axes of symmetry aligned. The moment of inertia of the plate, relative to its axis, is I. We immerse the plate in the water (Figure 1) and measured its torsion oscillations in two situations:5

• In ‘fresh’ water (ie with negligible autothixotropy), under assumption of a viscous damping of the water, the period of free damped oscillations is T1.
• In ‘stood’ water (ie with autothixotropy and viscous damping of the water), we suppose that it is necessary to add, to the quantities related to the elasticity of the filament with torsional rigidity kτ, the elasticity parameter of putative clusters of water molecules in the considered situation, represented by torsional rigidity kw. Then period of free damped oscillations is T2.

By measuring the periods of oscillation T1 and T2, we can determine the moment of inertia I (eg, from the plate dimensions and its mass), and calculate the equivalent torsional rigidity:

Quantitative experimental results

For the measurement, an aluminium plate with a thickness of 2.95 mm, width b=(47.59±0.03) mm, height h=(50.59±0.02) mm and mass 18.70 g, was used. Its moment of inertia was calculated from its dimensions and mass: I=(7.518±0.001)×10−6 kg m2. The plate was hung along its longitudinal axis of symmetry on a phosphor–bronze filament of cross-section of 0.025×0.2 mm2 and length of L=569 mm. The filament had a torsional rigidity kτ=(8.25±0.12)×10−8 Nm/rad.5

The plate was immersed in distilled and boiled water so that the upper edge of the plate was 14 mm above the level of the water surface. The water with a volume of approximately 400 ml was in a glass vessel with an inner diameter 80 mm and height 110 mm; the experiment was carried out at a temperature of 23°C. The period of the damped torsion oscillations was measured three times.

First in fresh water. The period of oscillation was T1=(101.7±1.2) s. Then the system was left at rest for seven days. Then plate was carefully rotated from this equilibrium position by not, vert, similar45°, and at that position it stayed. Then, the plate was given a torsional pulse, initiating damped torsion oscillations. The period of oscillation was measured ten times; resulting in T2=(5.34±0.06) s. The torsional rigidity of this system with autothixotropy was determined to be kw=(1.04±0.03)×10−5 Nm/rad. The degree of the level of autothixotropy of the system, is ascertainable by means of the measurement of critical angle (φu)crit.. For our system this was ≈340°.

Conclusions

On this basis, it is possible to formulate some additional hypotheses about clusters of water molecules:

1. Clusters of water molecules may be of macroscopic dimensions, on scale of centimeters.
2. Clusters of water molecules may be destroyed by boiling or intense stirring or shaking.
3. Clusters of water molecules have certain mechanical properties analogous to the properties of solid substances, such as elasticity/rigidity and strength, but these properties are much smaller than for solid substances with a relative magnitude of 10−6 or less.
4. Mechanical properties of clusters of water molecules show a certain hysteresis.
5. Water slightly deviates from an ideal Newtonian viscous fluid, because autothixotropy also appears in the form of internal static friction, although very weak.

Abstract

This paper discusses the nature of the active ingredient of homeopathic ultramolecular dilutions in terms of quantitative physics.

First, the problem of the nature of an active ingredient in ultramolecular dilutions is analysed leading to the recognition of the necessity of characterizing the active ingredient as a non-local quality.

Second, non-locality in quantum mechanics, which is used as a paradigm, is formally presented.

Third, a generalization of quantum mechanics is considered, focussing on the consequences of weakening of the axioms.

The formal treatment leads to the possible extension of the validity of quantum theory to macroscopic or even non-physical systems under certain circumstances with a while maintaining non-local behaviour. With respect to the survival of entanglement in such non-quantum systems a strong relationship between homeopathy and non-local behaviour can be envisaged. I describe how several authors apply this relationship. In conclusion, the paper reviews how quantum mechanics is closely related to information theory but why weak quantum theory and homeopathy have not hitherto been related in the same way.

Introduction

When I started basic research on homeopathy more than 20 years ago I endeavoured to describe homeopathic potencies according to the laws of physics as far as possible. This soon led me to the hypothesis of a field being responsible for the homeopathic phenomenon. In investigating this hypothesis I learned from biophysics that such a field has to be closely related to electromagnetism, because of the ability of living organisms to react in a specific way on electromagnetic signals.1 I concluded that the mechanism of homeopathic effects must be similar to resonances between electromagnetic waves and started to search for stored patterns of electromagnetic origin or, more generally, of physically measurable properties which differ between potencies and their solvent.

The results of the series of experiments that were carried out with a variety of standard physical–chemical methods2 were disappointing. Almost none of the experiments could reproduce results reported in specialist literature, and for no experimental arrangement could the results be forecast. However, the totality of experiments with nuclear magnetic resonance (NMR) showed a clear tendency in favour of a difference between potencies and their solvent in the water- and OH-portions of the ethanol–water-molecule.3 I was quite pleased with this tendency, which is now being investigated by other researchers,4 but I realized that looking for effects without having any clue of their significance is hazardous. Therefore, I started building models for the ‘Therapeutically Active Ingredient’ (TAI) and it soon became clear that models for the TAI have to have holistic character.5

While playing with models, I developed a construct which I called the ‘Sequential Box Model’ (SBM, see Appendix A). SBM is a thought experiment illustrating that the homeopathic phenomenon can be treated within physics with no consideration of the degree of dilution. Furthermore, the SBM explicitly underlines the long-standing presumption that for a TAI to emerge during the potentization procedure a quality beyond ordinary correlation between particles has to occur or be in existence already.

About this time the idea of the so-called ‘quantum computing’ was proposed in computer science.[6] and [7] This involves the idea of non-local correlations between states of entities. For my work, such non-local behaviour was the missing link between the SBM and a possible TAI, particularly as it was already known that non-local behaviour can occur in non-quantum systems under certain circumstances. The relationship between non-local behaviour of events in nature and the homeopathic phenomenon may give a clue to the ‘nature of the active ingredient in ultramolecular dilutions’ (NAIUD). It is the aim of this paper to analyse this relationship without going too far into technical details.

Necessity of a general principle

When we talk about the active ingredient of ultramolecular dilutions as used in homeopathy, we mean a non-material quality which—according to the principles of homeopathy—can be traced back to a substance. Moreover, this quality is understood to be able to make the symptoms of a patient disappear when administered via a vehicle. Many people call this quality ‘information’. Let us first look at the set of events that are required for a therapeutic active ingredient to develop out of a substance. In this context, the existence of a TAI is temporarily assumed as being proven by successful treatment (Figure 1).

1. First of all, a proving (homeopathic pathogenetic trial) must have been conducted resulting in a drug picture with specific symptoms.
2. A mother tincture is prepared from the substance.
3. Apart from some specific procedures for the preparation of low potencies that depend on the nature of the substance itself, the mother tincture is potentized stepwise with no consideration of the degree of dilution. Dilutions far beyond Avogadro’s number are used in daily practice.
4. When a homeopathic potency is prescribed, this is done according to the law of similars without consideration of the occurrence or not, of any molecule of the original substance in the medicine administered.
5. An artificial disease is triggered off resulting in healing.

These points demonstrate that the active ingredient of homeopathic potencies might have a variety of possible originators, especially when we only look at the squares and arrows in Figure 1 separately. There is no reason as to why two or more of these originators should complement one another. But if we look at Figure 1 as a whole, the necessity of a general principle becomes obvious. For such a principle, the symptoms of the homeopathic drug picture, the principle of releasing hidden energies of the substances by potentizing, the law of similars and the triggering of an artificial disease are specific projections. The problem is, how to specify this principle, especially with respect to the following questions:

1. Could such a general principle possibly be derived from the presence of a physical field?
2. For ultramolecular dilutions, interactions between molecules of the solute and those of the solvent do not make sense in terms of current scientific understanding. How can this be resolved?
3. Are there any reliable arguments for a concept of a global influence being responsible for an active ingredient in homeopathic potencies? Rupert Sheldrake’s morphogenetic field8 might serve as an example of such a concept.

In physics, fields are inevitably linked to interaction between material partners via interaction-particles. Photons, for instance, are the interaction-particles of the electromagnetic field.9 Thus, potentization as well as treatment with potencies—procedures that implicitly do not depend on matter–matter-interaction—are not primarily based on physical fields.

Figure 1. Schema of events which are required for a TAI to: (a) develop out of a substance, and (b) proved to be existent by successful treatment. Arrows represent procedures, they map states onto states.

Both procedures, however, suggest mind–matter and matter–mind correlations.

1. Neither a specific chemical nor a specific physical property of the original substance is known to be transferred during the preparation of potencies although mother tinctures, which of course contain many molecules of the original substance, are mandatory for a starting point of this procedure. Potentization here appears to embody a procedure that relates matter to mind.
2. No common donor–acceptor-mechanism is known to be responsible for the effects of potencies. Treatment appears to embody a procedure that relates the ‘mind of matter’ to the ‘mind of illness’. The latter of course itself is strongly related to biological matter and is often looked upon as a relationship belonging to psychosomatics.

Are these correlations better described by interaction mechanisms that are not linked to particles? A possible alternative is non-local correlations, known from specific effects in quantum physics. Roughly speaking these correlations have the following characteristic:

1. Non-local correlations between systems or entities represent a real simultaneous behaviour of the correlation partners because no interacting particles (which have a finite speed and therefore cause a time delay) are necessary for interaction.
2. Non-local correlations are not able to interchange matter but only non-material information.
3. Non-local correlations are, in principle, independent of spatial distances.

How non-locality arose

Although Einstein was one of the founders of quantum physics, he did not accept quantum mechanics as to be a complete description of the phenomena of the micro world. He explained the reason for this attitude in a paper which he published with Podolsky and Rosen in 1935. In this famous paper, the three physicists described a thought experiment in which two physical quantities have simultaneous reality.10 For Einstein, this was a counter example for the completeness of quantum mechanics as a description of nature and for the rest of his life he did not change this attitude. He was not willing to accept counter-intuitive features in the description of nature. Schrödinger later on called this counter-intuitive property of quantum systems ‘entanglement’. Only three decades later, John Bell11 gave a theory-based criterion by which it was possible to decide whether a system is a quantum system or not. This criterion was applied in 1982 by Aspect and co-workers to an experimental arrangement in which they showed, for the first time, that entangled states can occur in quantum systems.12 Since then many properties of systems in micro-physics have been demonstrated in experimental arrangements based on entanglement.[5], [6] and [7] All have one thing in common: ‘Entanglement in quantum systems’.

What is entanglement?

Entanglement is a highly counter-intuitive quality of quantum systems. The fact that entanglement is irrelevant to Newtonian physics does not justify the assumption that quantum physics is the only field where entanglement occurs. At least theoretically, entanglement can occur in any system that fulfils a certain set of axioms. Entanglement comes in various guises and it is not easy for non-specialists to see whether a phenomenon belongs to the category of entangled systems or not. For our purposes, it should suffice to get a clue what entanglement is, without too much technical fuss. Readers who are interested in a more precise explanation are referred to Appendix B.

As an example let us imagine a secluded island exclusively inhabited by females. Being asked what human beings are, the inhabitants of this island would most probably point their fingers at themselves. Similarly, the inhabitants of another island exclusively inhabited by males would identify human beings with males. For the rest of the world, human beings are females as well as males. This is a description of a factual connection, where a generic quality in a system has a different meaning in its subsystems. Furthermore, if we look at pairs of human beings there might be couples among them in the rest of the world, in total contradiction to the local meaning in the two islands.

A generalization of this example leads to the following. Let p1 be a particle in a system A and let p2 be another particle in a system B. System A and system B are assumed to be disjoined, ie have no common points/particles. System A rules the behaviour of particle p1 and system B does the same for particle p2 (see Figure 2).

Figure 2. Schema of two entangled systems A and B. p1 and p2 are assumed to be correlated. Seen from (A+B) correlation can be observed. Seen from A or B only local observations are possible.

It might be that states of the totality of the two systems occur which cannot be recognized in system A or in system B alone, but are exclusively linked to the recognition of (A+B) as a third generic system. In the above example as well as in the following generalization constellations, in which global observations are not compatible with local ones, are possible. This is the idea behind entanglement.

Weakening the axioms of quantum mechanics

Quantum mechanics deals with states zi and observables P, Q of quantum systems. Examples of observables are momentum, angular momentum, etc. Observables are thought to act as maps on the set of states. So, an observable P maps a state z1 into another state z2. Onto z2 a second observable Q may be applied resulting in a state z3. Unlike in classical mechanics in quantum mechanics one does not always have P(W(z))=Q(P(z)) or equivalently:

Pring operatorQQring operatorP≠0,

where ‘ring operator’ is to be interpreted as ‘apply to’, where ‘0’ on the right-hand side of this inequality denotes the ‘zero-operator’ and where states ‘z’ have been omitted. Such a relation is known as a ‘commutation-relation’ of the two observables. Using states and observables as well as their relation to each other, quantum mechanics can be described as an algebraic system whose behaviour is ruled by a set of axioms that reflect the physical properties.In 2002, Atmanspacher et al. published13 the idea that weakening the axioms of quantum theory (weak quantum theory, WQT) could lead to theories that are no longer quantum systems or even physical systems at all, but which still have the property of possible entanglement. To be more precise, Atmanspacher et al. considered systems that comply with the following conditions (see also14):

1. Systems are any part of reality.
2. Systems are assumed to have the capacity to reside in different states. The set of states is not assumed to have the structure of the above-mentioned abstract space.
3. Observables are features of a system which can be investigated. They map states into states.
4. The composition Pring operatorQ of two observables is also an observable. P and Q are called compatible if they commute (ie Pring operatorQQring operatorP=0).
5. To every observable P there is a set of different (possible) outcomes.
6. There are special observables (propositions) whose possible outcomes are either ‘yes’ or ‘no’. They follow the laws of ordinary proposition logic and have specific spectral properties (omitted here).

Within these conditions entanglement arises if global observables P pertaining to all of a system are not compatible to local observables Q pertaining to parts of the system (iePring operatorQQring operatorP≠0).

WQT and homeopathy

Since WQT systems are not necessarily quantum systems, WQT could be a tool to develop models for phenomena which are not quantum but have features which resemble entanglement, for instance, homeopathy. Several authors therefore have applied WQT to the homeopathic phenomenon. Walach, one of the co-authors of the original WQT paper,15 presented a model in which the two semiotic processes ‘substance and potency’ as well as ‘drug picture and symptoms of the patient’ are assumed to be entangled by the law of similars. Milgrom has sketched a model for the homeopathic phenomenon in which the three pairs ‘Patient and practitioner’, ‘patient and remedy’ as well as ‘practitioner and remedy’ are assumed to be entangled in pairs.16 In a metaphorical way he derives, in succeeding papers, from this entanglement triangle an astonishing variety of principles of homeopathy.

Both models presuppose the validity of WQT for the specific situation in homeopathy and Milgrom, at least, deduces implications which reflect the way homeopaths think. In terms of logic, the approach of these two models is called the sufficiency part of a proof. The necessity part would be the proof that the assumptions which underlie homeopathy such as the potentization, the law of similars, etc., fit the preconditions of WQT.

I have tackled the TAI problem in a previous paper.17 This is where the SBM (see Appendix A) becomes relevant as a thought model, because it characterizes homeopathic potencies as a real physical system in which an unknown inner correlation is sought. In essence, paper17 showed that sets {Ji1,…,im·σi1,…,im·σi1,…,im} of spin-like states, where indices i1,…,im vary over permutations, fit the axioms of WQT for an arbitrary big system BN in the SBM. The sets {Ji1,…,im·σi1,…,im·σi1,…,im} are a generalization of couplings (Jik·σi·σk) of two spins, in NMR-theory, for instance. The generalization strongly suggests to investigate the possibility of global couplings instead of pair-to-pair couplings.

In summary, a number of arguments exist for non-locality being the general principle underlying the NAIUD. Quantum mechanics, however, cannot be considered, without further investigations, the theoretical frame for the NAIUD. The paradigm is rather non-locality. Quantum physics is merely the scientific discipline where non-locality has proven to occur in reality. Figure 3 gives a schematic classification of phenomena which can be treated within quantum mechanics, and those which have less structure in the set of their states and therefore need another theoretical environment, WQT. Questions concerning the NAIUD might even go beyond WQT.

Figure 3. (I) The set of phenomena understood by quantum mechanics (essentially quantum physics); (II) the set of phenomena possibly understood by weak quantum theory (ie quantum physics and beyond); and (III) the set of phenomena belonging to homeopathy, possibly not a proper subset of II. Although quantum mechanics is an excellent paradigm for entanglement occurring in nature, quantum mechanics itself is not the frame in which NAIUD can be described.

Entanglement and information in quantum physics and beyond

It is the purpose of this section to explain the considerable difficulties one should be aware of when applying WQT instead of normal quantum mechanics to systems in nature.

This will be exemplified by the difficulties which arise when the attempt is made to translate ‘informational content’ (=entropy) in a quantum system to a system which is not quantum but which can be investigated by WQT. For formally correct representations of the factual connections given here, the reader is referred, for instance, to.6

The key concept of classical information theory is that of Shannon entropy. According to this concept, the entropy of a random variable A quantifies how much information we gain, on average, when we learn the value of A. Conversely, the entropy of A measures the amount of uncertainty about A before we learn its value. Thus, on the one hand, entropy measures the uncertainty associated with a classical probability distribution. On the other hand, in quantum ensembles density operators ρ, which represent the statistics of ensembles of different molecules in different states, formally replace probability distributions.

It was John von Neumann’s brilliant insight that in quantum mechanics the entropy S(ρ) of ρ can be expressed by the formula

where λx are the eigenvalues of the density operator ρ. If entanglement between two subsystems of a quantum system occurs and if one considers the density operators of these subsystems separately it can be shown that the von Neumann entropy of one of these reduced density operators is a measure of the degree of entanglement. This measure has an upper bound log(s), where s (the Schmidt-number) is the dimensionality of an abstract space in which these states ‘live’. Clearly, the bigger the s, the more the particles or states entangled. Applied to an arbitrary box BN of the SBM this suggests that the bigger the box BN is, the larger s has to be chosen and therefore the larger the measure of the amount of information.These considerations, however, presuppose entanglement of those particles being directly concerned. If we turn to a situation where WQT has to be applied instead of quantum mechanics, many of the basic constituents are no longer present or at least no longer adequately defined. For instance, if the set of states is structured so poorly then the above formula for von Neumann entropy makes no sense.

Discussion

The principle of non-local behaviour of systems in nature, first investigated in the context of the counter-intuitive phenomena of quantum physics, is not necessarily restricted to physics at the micro scale. This is the essence of WQT. Roughly speaking WQT shows that in every system where local and global observables do not commute with each other non-local behaviour is possible. For some authors, WQT was the reason for using non-locality to characterize the nature of the active ingredient of ultramolecular dilutions. Some models have simply drawn consequences from such a possible generalized non-locality, another looks at the real potentization procedure, asking what non-locality might contribute to an active ingredient. But WQT is not known to be powerful enough to describe the NAIUD entirely.

So the question arises, why considered WQT in such detail in connection with homeopathy? The answer is simple. With WQT, for the first time, special emphasis is placed quantitatively on entanglement as an idea. Moreover, WQT has shown to be a powerful tool for the characterization of the physics of the class of mathematical problems which arise when the NAIUD is to be described.

It is a great temptation to use WQT as a special way of describing the laws of quantum physics. People who do so tend to ignore the restraints given of WQT and use it as a theory applicable to everything, including the NAIUD. This is certainly not the right way to describe the NAIUD. An attempt to characterize the informational content of a system to be investigated by WQT, shows that it is not easy to generalize the concept in quantum mechanics to WQT or beyond.

Of course, all these considerations do concern the NAIUD in modelling situations. The question is, why do such work instead of looking for the TAI in experiments? The answer is that model building is a method of finding a way of thinking which allows us to understand a set of phenomena in a wider context. In contrast, experimental work tends to reductionism. I hope that both tendencies will ultimately meet.

Appendix A. The sequential box model (SBM)

Imagine a certain volume of mother tincture is present in a box B0. Then imagine the contents of B0 are poured into another box B1, 10 times bigger than B0 and already 9/10th full of solvent. Imagine then B1 being vigorously shaken as in the preparation procedure of homeopathic potencies. Imagine then the whole content of B1 being poured into another box B2, 10 times bigger than B1 and again 9/10th full of solvent.

This procedure can be continued to an arbitrary box BN and it is clear that:

1. In every Box BN the whole volume of mother tincture is present, ie the problem of high potencies can be, at least in a thought experiment, treated physically.
2. If one attempted to conduct this experiment in reality the procedure would come to an end very soon because of the unrealizable dimensions of the boxes.
3. The higher N grows the less probable is the occurrence of a molecule in a random sample taken out of BN. This means that in BN an additional property has to be present which carries the information of B0. This property has to be non-local.

Appendix B. Entanglement

Mathematicians represent every point in the three-dimensional space of our experience as a sum of multiples of vectors of unit lengths in the x-, y– and z-axes. In the same way, they often represent objects in abstract spaces as sums of multiples of basic elements of these spaces. A direct application of this to quantum physics leads to the following.[6] and [7]

The states of quantum systems are mathematically represented by elements (points in) of an abstract Hilbert-space H. If points in this space are denoted by ψ and if the basic elements of H are denoted by phii (i=1,2,…), representations of states look like

This is commonly known as the principle of superposition in quantum mechanics, ie a wave function ψ is the superposition of multiples ai of basis ‘waves’ phii. In case of two particles forming two different systems we have the two representations:

where the numberings (1) and (2) are used to distinguish between the two. For the sake of clarity, we also index the Hilbert-spaces belonging to each of these representations (and get H1 and H2, respectively) although they are usually identical.The crucial point now is the consideration of a system consisting of the two particles as a whole. In this case, it is necessary to construct another Hilbert-space H=H1circle times operatorH2 out of H1 and H2 in such a way that this new system ‘lives’ in H1 and in H2 at the same time. In order to achieve this, a so-called tensor-product H1circle times operatorH2 is formed. This is a new Hilbert-space whose points have the form

Click to view the MathML source

where Φi,j denote basis elements in H=H1circle times operatorH2 and ci,j their multiples. Entangled states are those (ψ(1)ψ(2)) for which the multiples ci,j cannot be written as

ci,j=aibj,

with ai and bj being the multiples from above and independent from each other.Remarks

1. The above relation between states can be interpreted as the possible arising of additional qualities when two single systems are looked upon as a whole.
2. The set of entangled states in most of quantum systems is not empty. For many systems, the subset of possibly entangled states is much bigger than the non-entangled.
3. The above characterization is not restricted to pairs of particles.
4. States (ψ(1)ψ(2)) in H=H1circle times operatorH2 which cannot be split into products of pure states in H1 and H2, respectively, might be imagined as the pure states of the composite system.
5. The description of entanglement in quantum mechanics, which is a counter-intuitive, strongly depends on a mathematical apparatus with a rich structure.
