| Determinism | Genz | II 250 Time/Newton/mechanics/Genz: in Newtonian mechanics, not only the earlier point of time determines the later point of time, but also vice versa the later determines the earlier one. >Isaac Newton. Deterministic/Genz: we must distinguish between forward deterministic laws and forward and backward deterministic laws. >Laws, >Natural laws. II 251 Question: are there also purely backwards deterministic laws? Definition Time/Genz: as long as we do not know anything else, we can simply define time as the direction in which deterministic laws of nature apply. This is necessarily identical to the direction in which the order cannot increase. >Time, >Space, >Time reversal, >Time arrow, >Order, >Symmetries, cf. >Chirality. II 252 Deterministic/time/forward/backwards/quantum mechanics/Genz: the deterministic laws of quantum mechanics are deterministic in both temporal directions. II 253 N.B.: but it does not say whether they are the same in both time directions! The fact that they are not the same was first shown directly by an experiment in 1998. Before: the "CPT theorem" had already made the same prediction: CPT-Theorem/Genz: the CPT-Theorem says together with the "CP violation" that backwards deterministic laws of quantum mechanics must differ from forward deterministic laws. Experiment 1998: a K-Meson (neutral) can develop into its anti-particle. This can also be done in the opposite direction, but the process must then proceed more quickly (asymmetry). II 254 N.B.: then we can decide from the laws of nature alone, whether we have a real process that takes place in time, or whether a backwards running film is shown by a physical process. Not time-reversal-invariant: for example, the transformation of a K-Meson into its anti-particle is not time-reversal-invariant. Experiment: has of course not been observed directly, but by observations on numerous particles in the same state. Asymmetry/Genz: asymmetry only applies to the duration of the process, not to it itself. >Asymmetry. |

| Natural Laws | Pinker | I 344 Mirror/natural laws/Pinker: for all objects and processes in the universe is true that one cannot know if one sees the thing itself, or its mirror image - exception: decay of cobalt 60: emits preferably particles at the South Pole. >Symmetries, >Asymmetry. Chirality/Pinker: random, not predetermined by nature - the mind treats both cases as if they were the same. >Chirality. I 346 Language: the words "next to" say nothing about the right and left - but there is nothing appropriate for up and down or in front and behind. >Localization, >Local/global, >Reference system. I 347 We are quite insensitive to right/left, a tiger may come next time from the other side - Definition "right"/encyclopedia/Pinker: "eastern direction, if you look north". I 352 Mental turning: the mirror image must be fold in the fourth dimension. I 382 Natural Law/Law/Pinker: the laws of physics determine that objects with a greater density than water are not on the surface. Selection along with physics specifies that objects that move quickly, are streamlined. >Selection. Genetics causes that the offspring resembles the parents. The human intentions provide chairs with forms and materials that turn them into stable seating. |

| Phenomena | Feynman | I 736 Phenomenon/Feynman: (context here: magnetic field, coil) the changeover from north to south should not concern us, the two are also mere agreements. -the change is not a phenomenon! ((s) The two would be reversed: top/bottom and right/left at the same time, therefore no change! (As if you looked at the original image from behind: now north is at the bottom, but the vector now also points to the right instead of to the left.) I 736 True Phenomenon/Feynman: for example, if we have an electron moving through a field that points into the book page: if we then use the formula for the force v x B, we find that the electron, in accordance with the physical law, will deviate in the displayed direction. The phenomenon is that we have a coil with a current that runs in a certain circumferential direction, and an electron that circulates in a certain way. That is physics, regardless of how we call everything. ((s) Because the electron is not both positive and negative at the same time.) Feynman: Now we carry out the same experiment in a mirror: now the force is reversed if we calculate it according to the same law, and this is good, for the corresponding movements are then mirror images. >Chirality. I 736 Reflection/Chirality/Symmetry/Feynman: the main thing is that in the study of any phenomenon there are always two or an even number of right-handed rules and that the phenomena as a result always look symmetrical. However, it may appear as if we could indicate the north pole of a magnet! E.g. compass needle really points north. Vs: but of course this is again a local property that has to do with the geography of the earth. It is as if we were talking about in which direction Chicago is (north of Pittsburgh), so it does not count! That the compass needle has a bluish color is only a convention! If, however, a magnet had the property that small hairs grow on its north pole, but not on the south pole, that would be the end of the law of mirror symmetry. E.g. telephone call to a Mars resident: we could send him right-polarized light and say: "This is right-turning light". I 737 We could indicate our size in the diameter of hydrogen atoms. And this is how absolute length can be defined. But we could not define "left" with the fact that our heart beats on the left side. Maybe his beats on the right! >Objectivity, cf. >Twin Earth, >"Meanings are not in the head". |

| Space | Kant | I 85 Space/relativism/rationalism/Leibniz: (according to Kant): only capability exists of the mutual relationship of the things in it. KantVsLeibniz: counter-example: incongruity of left and right hands or mirror image - an inversion does not restore the identity here. >Chirality. --- Strawson V 28 Space/Time/Kant: totality seems to impose a disjunction on us: either limited, there is one last element, or unlimited. Since the antinomies are not empirically decidable, it thus confirms that space and time only exist as phenomena, and not as things in themselves. >Antinomies/Kant. StrawsonVsKant: it is not clear if there is no empirical solution. V 48 Space/Time/Kant: not produced by things, but by the subjects - space and time are states of consciousness - state of consciousness: not of high importance, merely effects of things, not their states. >Subject/Kant, >Perception/Kant, >Experience/Kant. V 49 Space does not arise from experience, but experience presupposes space. >Time/Kant. |

| Kant | Wittgenstein Vs Kant | Brandom I 75 WittgensteinVsKant: standards pragmatic, not explicit. --- Münch III 327 WittgensteinVsKant: new: regulated use is viewed (only) constitutively for all intuitive beyond the realm of concepts. Kant considered the descriptive as another ability. Precisely the "view" with a radically different procedure. Elmar Holenstein, Mentale Gebilde, in: Dieter Münch (Hg) Kognitionswissenschaft, Frankfurt 1992 --- Kant I 12 I/Kant: general I (an I, which is produced by the moral) overcomes affective subjectivity. - Problem: the absolute I, in the I-experience I burden myself with the affective and sometimes psychological pathos of existence: to be unique, but still not neccessary. - Fear of nothingness, helplessness of reason. --- Kant I 13/14 The Unconditional: necessary idea of reason: to think the unconditioned without contradiction. The conditional is meaningless, must be eliminated in the moral purification of the self. --- Kant I 14 WittgensteinVsKant: In relation to the Absolute, there is nothing to see, nothing scientifically expressible anyway. "The solution to the problem of life is seen in the vanishing of this problem." --- Putnam III 220 WittgensteinVsKant/Putnam: you can read it this way that the language game so far resembles our lives, since neither the game nor life is based on reason. Thus, a core of Kantian philosophy is disputed. Wittgenstein II 35 There are no true a priori propositions (the so-called mathematical propositions are no propositions). WittgensteinVsKant. --- IV 109 Chirality/WittgensteinVsKant/Tractatus: 6.36111 right and left hand are in fact completely congruent. That you cannot bring them to cover one another has nothing to do with that. One could turn the gloves in a four-dimensional space. |

| Quantum Mechanics | Einstein Vs Quantum Mechanics | Esfeld I 256 Incompleteness/Quantum Mechanics/QM/EinsteinVsQuantum Mechanics: For example, suppose two electrons are emitted from one source and move away with opposite spin in opposite directions. Overall state: singlet state. Einstein/Podolsky/Rosen/EPR: if the result of a measurement of the location or momentum of one system is given, then we can predict with certainty the result of the measurement of the same observables of the other system. (without intervention) I 257 Consequence: the quantum mechanics is incomplete. There is therefore an element of reality that corresponds to this physical quantity regardless of whether the second measurement is actually performed. This exists before the first measurement. The quantum mechanics is incomplete because it makes everything dependent on the measurement and therefore does not recognize this element. To justify this one needs the two principles of separability and local effect. Local Effect: to exclude that there is an interaction between the measurement on the first system and the reality on the second system. Separability: to exclude that the determination of the local properties depends on something other than the state the system is in. Einstein-Podolsky-RosenVsQuantum Mechanics: further conclusion: quantum systems simultaneously have a definite numerical value of two or more incompatible observables. I 258 For example, an experimenter only decides clearly after the emission which observable he wants to measure. Separability and local effect imply that this decision is irrelevant. Nevertheless, once the decision has been made, we can predict the value of the corresponding observable for the other system. Einstein-Podolsky-Rosen: therefore the two systems must have a definite value of all observables between which the experimenter can choose. Einstein did not consider this conclusion to be self-evident because it is based on the assumption of separability and the local effect. I 271/272 Metaphysics/Science/Esfeld: Separability and local effect are metaphysical principles in the sense that they are a precise formulation of assumptions that are at the center of our everyday view of nature. I 271/272 The question of whether quantum mechanics is complete also seems to be a metaphysical question. It depends on whether we underline separability and local effect as the foundation of science. Bell's inequality/Bell/Esfeld: Bell has eliminated the seemingly clear distinction between physics and metaphysics! Metaphysics: Einstein's realism shows that metaphysics has predictable consequences that can be tested. "Experimental Metaphysics"/Shimony: (Ferdinand Gonseth, 1948, Michele Besso, 1948): are similar to Quine's position: rejection of the separation between mathematics, science, and philosophy. Every element of our knowledge can be subject to revision. I 273 Thesis: metaphysical questions cannot be decided by experiments! On the contrary: EinsteinVsQuantum Mechanics must be understood in the sense of the Quine-Duhem-Thesis: no separation between metaphysics and physics in quantum mechanics. For example, Bell's experiments can be seen as a test of two hypotheses, namely the conjunction of parameter independence and result independence. But the point is: what you think is what the Bell experiments confirm or disprove depends on what background assumptions you base yourself on. Hennig Genz Gedankenexperimente, Weinheim 1999 VIII 216 Einstein-Podolsky-RosenVsQuantum Mechanics/EPRVsQM/Genz: incompleteness of Quantum Mechanics: Spin has an element of reality. Since quantum mechanics can only consider one of these elements of reality, it is incomplete. Einstein-Podolsky-Rosen Argument/Version Bohm: For example, a part of it rests in the laboratory and decays in a time interval into an electron and a positron. (There is no such thing, but it does not matter). (In the real experiment (Aspect) photons were assumed). If Gretel detects the electron, she can be sure that Hänsel has the positron. From a quantum mechanical point of view, the particle pair is a single system. VIII 216 The angular momentum of the particle decaying in its resting system is zero, since the conservation law applies to the angular momentum, it is also zero for the decay products. If, however, only the spins of the particles contribute to their total angular momentum, the law of conservation becomes a conservation law for the sum of the spins. Consequently, the two spins remain coupled. But now the coupling of the spins to the total spin zero guarantees more: that the sum of the settings of the spins in any direction is zero. If the total spin were not zero, it could be that it is zero in x direction, but not in y direction. VIII 217 Example Einstein-Podolsky-Rosen/Bohm: Problem: Gretel can align her star Gerlach apparatus as she wants. The alignment of the device determines which component of the spin of the entering particle should have a "sharp" value with spin 1/2. Hänsel and Gretel choose directions for x or y (perpendicular to the direction of propagation z). Since the two particles fly apart, the chirality is different! Both now want to measure "transversal" spins perpendicular to the extension. VIII 218 Gretel: measures in x direction plus or minus. If she turns the apparatus by 90°, she measures in y direction, again plus or minus. N.B.: Hänsel always measures the opposite. If Gretel has the apparatus in the same direction as Hänsel, she measures the opposite of his spin. If she now turns it in y direction, she has to measure the opposite again, even if Hänsel has not turned his apparatus. Einstein-Podolsky-Rosen: now claim that Gretel can use it to determine Hänsel's spin in both the x and y directions without disturbing Hänsel's positron in any way. Quantum MechanicsVsEinstein-Podolsky-Rosen: actually it is not the case according to quantum mechanics. Before the measurement it is pointless to speak of a state at all. VIII 219 Bertlmann's Socks/Genz: are not particularly exciting. Corresponds to the "glove correlation": if I find one, I know that I have lost the other. VIII 220 Quantum MechanicsVsEinstein-Podolsky-Rosen: also the spin operators of the positron do not exchange with each other, but a statement about the "sum" is valid: σxσy - σyσx = 2iσz. Translated into the formalism of quantum mechanics, the conclusion of Einstein-Podolsky-Rosen is that the state | > of the positron must be both an eigenstate of σx and of σy for certain eigenvalues mx and my. But the quantum mechanics does not know such a state! Unlike the product of operators, the product of eigenvalues is independent of the order! 0 = (mxmy - mymx) | ψ > = (σxσy - σyσx) | ψ > = 2iσz | ψ >, so that | ψ > of σz would have to be destroyed (σy | ψ > = 0). But because σz, just like σx, and σy can have only 1 and -1 but not 0 as eigenvalue, there can be no such state! But the contradiction is one between the formalism of quantum mechanics and the demands of Einstein-Podolsky-Rosen and none with experimentally verifiable statements. |
