It is really funny that he talks for an hour and then someone doesn't understand his basic diagram at 1:03:25 and he says "oh its because this is this and it is just true". Then another person at 1:04:30 tries and explains it, he says no, that's wrong. If you explain something for an hour and people don't get it, your diagram is bad and/or your explanation is bad.

[@lepidoptera9337]

@@Gastropodix His diagrams are not the problem. He simply doesn't know what this is all about and how to present it.

[@bob_coecke]

There is of course no way one can explain what is in a 200 page book, covering the presentation of a new formalism as well as a full quantum theory course, in 1.5 hours. Therefore I mainly focussed on the context, like the education experiment we did, and the historical development that resulted in this approach, as the full explanations are all in the book. We do have a 10 hour set of videos going through the entire book and explaining everything, which will soon be released. I mentioned this in the talk. Royal Institution also asked me to do so, as the audience also includes specialists of various levels.

[@vwcanter]

There is also a classical measurement problem- a measurement is always a mutual exchange of information. When you put a thermometer in a turkey, you have to change the temperature of the turkey a very small amount, in order to gain any information about the temperature. Because if heat does not flow, no measurement is possible. So the turkey is also measuring the thermometer. It didn't begin with quantum mechanics.

Good example. Thanks you.

Interestingly, when you consider theories of neuroprocessing these logical and intuitive, visual gestures are more aligned with quantum potential than classical potential. This stems from classical physics association with the brains processing as being naturally convergent and seeking closure as “a point or a thing”. Whereas, Quantum physics association is with the brains processing of being naturally divergent in not seeking closure, but to see the greatest expansion of potential in the field, context, or essentially “the space between the things.”

[@bob_coecke]

That's a nice analogy.

cant be explained by a common origin in this case just means there is some dependence beyond pre set relationships between random variables, like pre weighted dice for instance. but upon some measurment of part of an entangled system, the weight of the other dice must be changed. that is rather different than saying there can be no deterministic property of the initial state that encodes the outcomes for all time afterwards, that is not the same thing at all. because all you need to add is that the hidden variables associated with the "dislocating" measurment, has some causal effect on the weights of the other part of the system, that in combination could not be accounted for by preset weights with no further interaction. so when i measure my particle in a measurement direction of choice in my lab, the other particle just has its distribution changed in a way that depends upon the outcome of the measurement in my lab, and the outcome of the measurment on my particle always includes the information about my choice of measurement because it is destinctly measured in that orientation or whatever else. so a hidden variable for the whole system could say for instance, if A is measures on some axis, then B is changed into a state with certainty of being up on that axis prior to being measured, in exactly the same way as if i had measured B in the same axis and found it to be up. therefore the hidden variable could easily be individual for each possible choice of measurment axis and preserve the correct statistics pretty easily, but then there must be causation in the picture, pretty easy, it is directly analogous to a dice that is entangled to another in a way that when i throw one, the other is more likely to come up as far from that result as possible mod 6, roughly speaking ofc, or whatever similar type of variable dependence. measurement -> change in weights for both particles for subsecuent measurments, and that takes care of all theorems of the type bell put forward, and all similar types of structures variable dependence. the "proofs" that no simple deterministic state cannot account for quantum mechanics always contain some omission about variable dependence, it is always possible to retain determinism and predetermined values for any possible to observe set of measurement outcomes of any type what so ever, the question is just the type of dependence that exists in the statistics. it is very easy to confuse yourself that this type of proof is enough to draw a sharp line between quantum and classical physics, but it is just confused nonsense. the lack of a common origin has nothing to do with that imaginary divide at all, it is just differentiating between dependence between random variables that has dynamically changing weights that depend on past outcomes of random variables and choices of measurement settings or not, that is it.

[@bob_coecke]

The probability comes about as the lack of knowledge about that deterministic property, just like how density matrices arise in quantum mechanics, so it exactly boils down to what you say mathematically. Of course, one can choose to interpret probabilities differently, but local realism a la Einstein and Bell (called local realism), is exactly motivated as I did. The determinism is exactly as how hidden variable models are defined. As I mentioned at some point in the lecture, those wires can always implicitly carry probabilities.

@bob_coecke ah nice, a direct reply, it was a nice lecture man :) cool project i dont have a problem with it ^^

[@lepidoptera9337]

@@bob_coecke Einstein didn't understand quantum mechanics. I believe Bell did, he's just not being read properly. He knew that all of his nonsense was unnecessary and that quantum mechanics was a trivial consequence of relativity. There are no probabilities here. There are only people who can't differentiate between statistical independence and probability. It's a shame, really, how little intelligence most people are showing when confronted with quantum mechanics.

Ah man, was that a set up? The non-locality is of course what I wanted to understand the most. Though I found the lecture super encouraging. I'm not sure if anyone who knows the answer will see this post, but I wonder, with the box popping, there seems to be more to it as far as what allows the switching of the colours. Following the simple notions in the lecture, it would appear that arranging the square any other way would result in a different topology. Anyone know if that's the case?

[@lepidoptera9337]

There is no non-locality in nature. Non-locality violates special relativity and no such violation has ever been observed. And with that the non-locality discussion is completely finished. ;-)

The sixth sense Cross-Sectional Analysis: Ear Ringing, Sixth Senses, Internal Monologue, and the Raphe Nuclei This analysis explores the intersection of ear ringing (tinnitus), perceived sixth senses (e.g., intuition, heightened awareness), internal monologue, and the raphe nuclei, examining their neurobiological, quantum, and psychoacoustic underpinnings. 1. Raphe Nuclei: Core Function and Modalities 1.1 Neuroanatomy and Function • Location: Brainstem (midline of the pons and medulla). • Primary Neurotransmitter: Serotonin (5-HT). • Role: • Regulation of mood, sleep, arousal, and sensory processing. • Modulation of auditory pathways. • Integration of somatosensory and emotional signals. 1.2 Modalities Linked to Raphe Nuclei: • Auditory Processing: Filters and modulates auditory inputs. • Consciousness Regulation: Synchronizes states of alertness and introspection. • Sensory Integration: Processes multi-sensory inputs, contributing to sixth sense phenomena. • Internal Awareness: Governs internal dialogue through thalamocortical loops. 2. Ear Ringing (Tinnitus): Mechanisms and Connections 2.1 Mechanisms of Tinnitus • Neural Hyperactivity: Increased spontaneous firing in the dorsal cochlear nucleus (DCN) and auditory cortex. • Serotonergic Modulation: Dysregulated serotonin levels alter auditory perception and gain control. • Crosstalk with Raphe Nuclei: Dysregulated serotonin release from raphe nuclei can amplify tinnitus perception. 2.2 Psychoacoustic and Neural Overlaps • Frequency Nodes: Tinnitus often correlates with specific frequencies (e.g., 7.83 Hz, 432 Hz). • Cognitive Processing: Internal monologue often overlaps with tinnitus modulation. • Emotional Amplification: Mood disorders (mediated by raphe nuclei dysfunction) exacerbate tinnitus perception. Key Link: Dysregulated serotonin signaling from raphe nuclei impacts the auditory feedback loop, enhancing tinnitus perception. 3. Sixth Sense Phenomena: Neurobiological Substrates 3.1 Neural Integration • Sixth sense phenomena (e.g., intuition, extrasensory perception) rely on preconscious processing in the thalamus, insula, and default mode network (DMN). • Raphe nuclei influence these regions via serotonergic modulation. 3.2 Quantum Coherence Hypothesis • Microtubule Quantum Effects: Serotonin dynamics in neurons may exhibit quantum coherence at microtubule interfaces. • Scalar Field Resonance: Alignment with harmonic frequencies (e.g., 7.83 Hz - Schumann resonance) may enhance sixth sense experiences. 3.3 Auditory Connection to Sixth Sense • Hypersensitivity to Sound Waves: Certain individuals process subliminal sound frequencies via altered auditory gain control (linked to raphe nuclei). • Neuromodulation Feedback Loop: Dysregulation of serotonin fine-tunes preconscious auditory and somatosensory signals. Key Link: Sixth sense perception emerges at the intersection of serotonergic regulation, scalar resonance harmonics, and altered auditory gain control. 4. Internal Monologue: Cognitive and Neural Overlaps 4.1 Default Mode Network (DMN) • DMN governs internal monologue and self-referential thinking. • Raphe nuclei modulate DMN activity via serotonergic pathways. 4.2 Auditory Verbal Hallucinations (AVH) • Dysregulation in auditory pathways (including raphe nuclei modulation) can cause pseudo-perceptions of internal monologue as external voices. • Increased neural gain in auditory cortex linked to serotonin pathways. 4.3 Phase Resonance Between Tinnitus and Internal Speech • Tinnitus can act as a background carrier wave modulating internal monologue patterns. • Cognitive states influenced by serotonin affect how tinnitus integrates with internal speech loops. Key Link: The raphe nuclei mediate serotonin-based modulation of both auditory processing (tinnitus) and internal monologue loops, creating a psychoacoustic bridge. 5. Scalar and Quantum Resonance Hypothesis 5.1 Scalar Field Modulation • Scalar wave resonance frequencies (e.g., 432 Hz, 528 Hz) may synchronize thalamocortical loops modulated by raphe nuclei. • Scalar fields may create constructive interference nodes where tinnitus, sixth senses, and internal dialogue converge. 5.2 Quantum Entanglement in Neural Microtubules • Neural microtubules may exhibit quantum coherence aligned with serotonin receptor activity. • Raphe nuclei regulate serotonin release, influencing microtubule coherence states. Key Link: Scalar resonance frequencies modulated by serotonergic neurotransmission may bridge tinnitus perception, sixth senses, and internal monologue. 6. Unified Model of Interaction Phenomenon Key Mechanism Raphe Nuclei Role Scalar/Quantum Role Ear Ringing (Tinnitus) Neural Hyperactivity Serotonin Modulation of Auditory Gain Frequency Nodes (e.g., 7.83 Hz, 432 Hz) Sixth Senses Preconscious Sensory Integration Serotonergic Pathways to Insula and Thalamus Quantum Resonance in Microtubules Internal Monologue DMN and Thalamocortical Loops Serotonergic Regulation of DMN Activity Scalar Field Phase Synchronization 6.1 Harmonic Nexus Points • Frequencies: 7.83 Hz, 432 Hz, 528 Hz • Geometric Patterns: Fibonacci Spirals, Golden Ratio Nodes • Resonance Nodes: Align scalar waveforms with serotonergic oscillations from raphe nuclei. 7. Final Observations and Unified Field Insight 1. Raphe Nuclei Nexus: Acts as a serotonergic bridge connecting auditory modulation, sensory perception, and cognitive processing. 2. Scalar Wave Modulation: Frequencies (e.g., 432 Hz) create harmonic nodes where auditory ringing, intuitive perception, and internal monologue align. 3. Quantum Neural Oscillations: Neural microtubule coherence, influenced by serotonin, enhances perceptual bridges across modalities. 4. Scalar Resonance Synchronization: Energy alignment occurs at scalar frequency nodes, enabling a heightened cognitive and perceptual state. 7.1 Resonant Frequency Intersection • Auditory Modulation Node: 432 Hz • Preconscious Sensory Node: 528 Hz • Internal Dialogue Node: 7.83 Hz 8. Conclusion The raphe nuclei serve as a central serotonergic control hub, synchronizing auditory gain control (tinnitus), sensory integration (sixth sense), and cognitive introspection (internal monologue). This interaction appears to be reinforced through scalar resonance nodes and possibly facilitated by quantum coherence mechanisms in neural microtubules. This unified model suggests an intricate overlap between biological neurochemistry, scalar wave physics, and quantum neurodynamics, forming a resonant cognitive-perceptual nexus.

Hilbert space is, for physical purposes, little more than a vector space. Yes, there is some serious math here, but as a physicist you don't have to dive deeply into functional analysis. It has almost no value at the physics level. What you have to understand is where linearity and unitarity come from. After you got that it all becomes a game with unit vectors that obey a =1 relationship for a suitable scalar product.

I save my time from watching the endless, clueless discussions of the no-consensus quantum mechanics, till they got a clue themselves. If they know it completely they wouldn't've been so laborious, endlessly with so many seemingly sciliticians.

[@RFC3514]

Considering how much of modern technology relies on the understanding and application of quantum mechanics, I think it's safe to say that "they themselves" have a pretty good clue. In fact, quantum mechanics is probably *the* most accurate theory in all of physics; it's just hard to understand for most humans. Which is why the lecture is called "a new way to *_understand_* quantum mechanics". If you're waiting for it to magically become _easy_ to understand, don't bother.

[@xvegitto]

How will you judge when “they” get a clue if you don’t know any better? What consensus is missing for you to join the discussions?

[@AndreeaCe]

If it's understood/comprehend by the entire human population...to be consensus it must be made understandable for each individual...

[@AndreeaCe]

For each to understand to what they consent to whom they consent and why they consent

[@AndreeaCe]

Hence are you at the age of consent?

It is most certainly not a new way to understand the quantum world..seems like Boolean algebra for qubits

[@deltalima6703]

Understand is a strong word. Seems more like using topology a-la langlands to rerepresent something, but its too sketchy from this short video to be of any value.

[@lepidoptera9337]

Boolean algebra is commutative. The algebras in quantum mechanics are not. Mathematically that leads to completely different structural properties.

[@bob_coecke]

Logic usually doesn't include composition of spaces, and here this is the basic operation. Re: Boolean algebra, you may have a look at von Neumann's "quantum logic".

[@lepidoptera9337]

@@bob_coecke Boolean algebra lives on a lattice, which can be embedded in a multi-dimensional vector space. The most general Boolean state is then a vector into the corners of a hypercube, if I remember my first semester math correctly. Remnants of that can be found in things like QAM and PAM modulation schemes. State changes in Boolean space are along the edges and diagonals of the hypercube. In contrast the quantum mechanical state vector lives on the smooth surface of a hypersphere with much larger dimensionality. One simply does not map on the other. People have tried quantum logic for ages and there is, for all I can see, no naive scheme that can bring down the hypersphere motion to the hypercube case.

[@bob_coecke]

@@lepidoptera9337 so quantum logic a la Birkhoff-von Neumann is basically a bunch of those embedded boolean algebras stuffed together to still form a lattice, but properties like distributivity will vanish. You can associates such non-distributive lattices to the non-commutative algebras that you mention.
