About the doubleslit experiment of Dean RadinDean Radin and his team have done a very interesting experiment (see this and this) testing the idea that observer induces state function reduction. Experiment The experiment is a modified double slit experiment. In double slit experiment a laser beam arrives to the screen via two slits and interference pattern is generated as if photons would behave like waves localized at screen. If one adds detectors at the slits, either detector fires and detects the passingby by photon, and interference pattern disappears with optimal detection efficiency. The idea is to add a subject person (S) at distance of two meters. S imagines of measuring that electron passes through either slit. One can say that S intends to add a "detector" to either slit or both of them so that a state function reduction selecting either slit occurs. This experiment differs from experiments in which S tries to affect the ratio of frequencies of 0:s and 1:s in random series of bits: S does not try to force the electrons to pass by either slit. There is a feedback represented as sound/yellow light whose height/intensity coded for the amount of the reduction of the height of the peak. There are two kinds of participants: meditators and those who have no experience in meditation. The results of the experiment are thoroughly discussed in the Youtube lecture or Radin (see this). To my opinion the results are amazing. In one experiment it was found that the height of the peak of the Fourier transform of the intensity distribution of the diffraction pattern is reduced. In second experiment the depth of bottom of the through of distribution was reduced. As if the intention would induce with some probability to perform the measurement selecting the photon path. The effect was small but appeared systematically for a group consisting of meditators. For persons without experience in meditation the effect averaged out also in this case it was present in the beginning of the experiment when subject person were not bored by the repetitive character of the experiment. The longer attention span of meditators could partially explain this. Even more amazing finding was that in a variant of the experiment realized in internet the results were also positive although the persons intending to induce the experiment. Arguments of different skeptic The standard argument of skeptic is that statistics is poor, that the experiment is even fraud, etc... One can however consider more refined and more imaginative objections. Let us make a digress from the usual behavior of skeptic and assume that the effect was real. If the meditators could induce the measurement by intention, one expects that also the experimenter could have done it. To how high degree the outcome was due to the experimenters and how much due to the meditators? Experimenter also had the theoretical expectation that meditators are better in inducing the slit detection. Could the wish that the theory is correct have caused subconscious intention about performing the detection in the case of meditators or not doing it in the case of nonmeditating subject persons? In the case of net experiment situation becomes even more problematic. One can imagine that also in this case the intention of experimenter could induce the detection  at least if experimenter is near to the system. Should experimenters have spent the period of experiments in Mars or at least in a distant holiday resort! Experimenters studying remote mental interactions are usually not rich people and presumably they did not do this. The experimenter effect is wellknown in parapsychology. Some experimenters are extremely successful. Could one think that they have strong intentional powers? Ironically, this would demonstrate the reality of paranormal effects of this kind but in a manner that can never convince the skeptics. There is evidence for this kind of effect in the testing of new medicines. Good results are obtained when the testers are enthusiastic and dream of a positive result. When they do same tests after some years, the results are worse. TGD based model The challenge is to understand how the S imagining a measurement telling that photon went through either slit could realize this intention. What does the detection mean and what it demands?
How could one realize these connections in TGD?

NMP and selfThe preparation of an article about number theoretic aspects of TGD forced to go through various related ideas and led to a considerable integration of the ideas. In this note ideas related directly to consciousness and cognition are discussed.
The view about Negentropy Maximization Principle (NMP) has coevolved with the notion of self and I have considered many variants of NMP.
Number theoretical Shannon entropy can serve as a measure for genuine information assignable to a pair of entanglement systems. Entanglement with coefficients in the extension is always negentropic if entanglement negentropy comes from padic sectors only. It can be negentropic if negentropy is defined as the difference of padic negentropy and real entropy. The diagonalized density matrix need not belong to the algebraic extension since the probabilities defining its diagonal elements are eigenvalues of the density matrix as roots of N:th order polynomial, which in the generic case requires ndimensional algebraic extension of rationals. One can argue that since diagonalization is not possible, also state function reduction selecting one of the eigenstates is impossible unless a phase transition increasing the dimension of algebraic extension used occurs simultaneously. This kind of NE could give rise to cognitive entanglement. There is also a special kind of NE, which can result if one requires that density matrix serves a universal observable in state function reduction. The outcome of reduction must be an eigen space of density matrix, which is projector to this subspace acting as identity matrix inside it. This kind NE allows all unitarily related basis as eigenstate basis (unitary transformations must belong to the algebraic extension). This kind of NE could serve as a correlate for "enlightened" states of consciousness. Schrödingers cat is in this kind of state stably in superposition of dead and alive and state basis obtained by unitary rotation from this basis is equally good. One can say that there are no discriminations in this state, and this is what is claimed about "enlightened" states too. The vision about number theoretical evolution suggests that NMP forces the generation of NE resources as NE assignable to the "passive boundary of CD for which no changes occur during sequence of state function reductions defining self. It would define the unchanging self as negentropy resources, which could be regarded as kind of Akashic records. During the next "reincarnation after the first reduction to opposite boundary of CD the NE associated with the reduced state would serve as new Akashic records for the time reversed self. If NMP reduces to the statistical increase of h_{eff}/h=n the consciousness information contents of the Universe increases in statistical sense. In the best possible world of SNMP it would increase steadily. 3. Does NMP reduce to number theory? The heretic question that emerged quite recently is whether NMP is actually needed at all! Is NMP a separate principle or could NMP reduced to mere number theory? Consider first the possibility that NMP is not needed at all as a separate principle.
Hitherto I have postulated NMP as a separate principle. Strong form of NMP (SNMP) states that Negentropy does not decrease in "big" state function reductions corresponding to death and reincarnations of self. One can however argue that SNMP is not realistic. SNMP would force the Universe to be the best possible one, and this does not seem to be the case. Also ethically responsible free will would be very restricted since self would be forced always to do the best deed that is increase maximally the negentropy serving as information resources of the Universe. Giving up separate NMP altogether would allow to have also "Good" and "Evil". This forces to consider what I christened weak form of NMP (WNMP). Instead of maximal dimension corresponding to Ndimensional projector self can choose also lowerdimensional subspaces and 1D subspace corresponds to the vanishing entanglement and negentropy assumed in standard quantum measurement theory. As a matter fact, this can also lead to larger negentropy gain since negentropy depends strongly on what is the large power of p in the dimension of the resulting eigen subspace of density matrix. This could apply also to the purely number theoretical reduction of NMP. WNMP suggests how to understand the notions of Good and Evil. Various choices in the state function reduction would correspond to Boolean algebra, which suggests an interpretation in terms of what might be called emotional intelligence . Also it turns out that one can understand how padic length scale hypothesis  actually its generalization  emerges from WNMP.

Are all quantum jumps measurements of density matrix?The preparation of an article about number theoretic aspects of TGD forced to go through various related ideas and led to a considerable integration of the ideas. In this note ideas related directly to consciousness and cognition are discussed.
The original definition of self was as a subsystem able to remain unentangled under state function reductions associated with subsequent quantum jumps. The density matrix was assumed to define the universal observable. Note that a density matrix, which is power series of a product of matrices representing commuting observables has in the generic case eigenstates, which are simultaneous eigenstates of all observables. Second aspect of self was assumed to be the integration of subsequent quantum jumps to coherent whole giving rise to the experienced flow of time. The precise identification of self allowing to understand both of these aspects turned out to be difficult problem. I became aware the solution of the problem in terms of ZEO (ZEO) only rather recently (2014).

Adelic physics, imagination, and dark matterAn important step in the progress has been the discovery of Strong Form of Holography (SH). 2dimensional surfaces (string world sheets and partonic 2surfaces) are fundamental objects and 4D physics is a kind of algebraic continuation from this intersection of reality and various padicities in both real and padic sectors of the adelic Universe. 4D spacetime surfaces are preferred extremals of Kähler action making them effectively 2D in the sense that the 2D surfaces serve as "spacetime genes". Also the quantum states assignable to the 2D surfaces can be algebraically continued to the entire 4D spacetime. It is however quite possible that the continuation in the real sector to a preferred extremal of Kähler action fails. In padic sectors the possibility of padic pseudo constants, which are piecewise constant functions with vanishing derivative, makes the continuation much easier. This inspires the idea that imagination corresponds to these padic continuations. pAdic continuation might be possible whereas real continuation could fail: one would have imagined world, which cannot be realized as often happens! This argument becomes more precise as one realizes that SH is slightly broken: even information theoretically one has only effective 2dimensionality. This means that 4surfaces as preferred extremals are dictated by the data at string world sheets and possibly also partonic 2surfaces and by data discrete set of points with preferred imbedding space coordinates in the extension of rationals defining the adele structure by inducing the extensions of padic number fields. For padic number fields pseudoconstants make it easy to construct the algebraic continuation to a preferred extremal containing the discretization. For reals this is possible only in special cases. These discretizations correspond to realizable imaginations. Note that Galois group acts as symmetries in the space of spacetime discretizations and under certain conditions gives rise to a spacetime surface, which is a covering space with n sheets, n a factor of the order of Galois group. The identification h_{eff}/h=n is natural and reduces the hierarchy of Planck constants and dark matter to adelic physics. Ramified primes for the extension of rationals involved are preferred for extension and if the extension allows especially many realizable imaginations, it is surviver in the number theoretic fight for survival. Ramified primes for these extensions should be winners in the number theoretic evolution. Whether padic length scale hypothesis and its generalization follow from this conjecture, remains an open question. See the chapter Life and Death and Consciousness. 
Why metabolism is needed?The simplest and at the same time most difficult question that innocent student can make about biology class is simple: "Why we must eat?". Or using more physics oriented language: "Why we must get metabolic energy?". The answer of the teacher might be that we do not eat to get energy but to get order. The stuff that we eat contains ordered energy: we eat order. But order in standard physics is lack of entropy, lack of disorder. Student could get nosy and argue that excretion produces the same outcome as eating but is not enough to survive. We could go to a deeper level and ask why metabolic energy is needed in biochemistry. Suppose we do this in TGD Universe with dark matter identified as phases characterized by h_{eff}/h=n. At deeper level metabolic energy should closely relate to negentropic entanglement (NE) and thus information. Identification of these two is however not possible. I have considered several answers to the question why metabolic energy is needed. Here two answers will be discussed.

What happens in biocatalysis?Biocatalysis is a key mechanism of biology and its extreme efficacy remains to be understood. Enzymes are proteins and ribozymes RNA sequences acting as biocatalysts. 1. Conditions on biocatalysis What catalysis demands?
Hydrogen atom allows also large h_{eff}/h=n variants with n>6 with the scale of energy spectrum behaving as (6/n)^{2} if the n=4 holds true for visible matter. The reduction of n as the flux tube contracts would reduce n and liberate binding energy, which could be used to promote the catalysis. The notion of high energy phosphate bond is somewhat mysterious concept. There are claims that there is no such bond. I have spent considerable amount of time to ponder this problem. Could phosphate contain (dark) hydrogen atom able to go to the a state with a smaller value of h_{eff}/h and liberate the excess binding energy? Could the phosphorylation of acceptor molecule transfer this dark atom associated with the phosphate of ATP to the acceptor molecule? Could the mysterious high energy phosphate bond correspond to the dark atom state. Metabolic energy would be needed to transform ADP to ATP and would generate dark atom. Could solar light kick atoms into dark states and in this manner store metabolic energy? Could nutrients carry these dark atoms? Could this energy be liberated as the dark atoms return to ordinary states and be used to drive protons against potential gradient through ATP synthase analogous to a turbine of a power plant transforming ADP to ATP and reproducing the dark atom and thus the "high energy phosphate bond" in ATP? Can one see metabolism as transfer of dark atoms? Could possible negentropic entanglement disappear and emerge again after ADP→ATP. Here it is essential that the energies of the hydrogen atom depend on hbar_{eff}=n× h in as hbar_{eff}^{m}, m=2<0. Hydrogen atoms in dimension D have Coulomb potential behaving as 1/r^{D2 from Gauss law and the Schrödinger equation predicts for D≠ 4 that the energies satisfy En∝ (heff/h)m, m=2+4/(D4). For D=4 the formula breaks since in this case the dependence on hbar is not given by power law. m is negative only for D=3 and one has m=2. There D=3 would be unique dimension in allowing the hydrinolike states making possible biocatalysis and life in the proposed scenario. } It is also essential that the flux tubes are radial flux tubes in the Coulomb field of charged particle. This makes sense in manysheeted spacetime: electrons would be associated with a pair formed by flux tube and 3D atom so that only part of electric flux would interact with the electron touching both spacetime sheets. This would give the analog of Schrödinger equation in Coulomb potential restricted to the interior of the flux tube. The dimensional analysis for the 1D Schrödinger equation with Coulomb potential would give also in this case 1/n^{2} dependence. Same applies to states localized to 2D sheets with charged ion in the center. This kind of states bring in mind Rydberg states of ordinary atom with large value of n. The condition that the dark binding energy is above the thermal energy gives a condition on the value of h_{eff}/h=n as n≤ 32. The size scale of the dark largest allowed dark atom would be about 100 nm, 10 times the thickness of the cell membrane. See the chapter Life and Death and Consciousness. 
Symplectic structure for M^{4}, CP breaking, matterantimatter asymmetry, and electroweak symmetry breakingThe preparation of an article about number theoretic aspects of TGD forced to go through various related ideas and led to a considerable integration of the ideas. In this note idea about the symplectic structure of M^{4} is discussed although it is not directly related to number theoretic aspects of TGD.
