In what way has Deepak Chopra misused physics with regard to the consciousness of atoms?
By referring to the consciousness of atoms, for starters. However, I don't recall ever limiting myself to a specific way in which he misused physics. For example, we can look to his
Quantum Healing starting at the opening of the chapter "The quantum mechanical human body", in which he states:
"We need to consult the quantum to really understand how the mind pivots on the turning point of a molecule. A neuropeptide springs into existence at the touch of a thought, but where does it spring from? A thought of fear and the neurochemical that it turns into are somehow connected in a hidden process, a transformation of non-matter into matter.
The same thing happens everywhere in nature, except that we do not call it thinking. When you get to the level of atoms, the landscape is not one of solid objects moving around each other like partners in a dance, following predictable steps."
Where to begin? First, even physicists like Stapp and Penrose who propose that QM is needed to understand consciousness would never say we need it to understand how the "mind pivots on the turning point of a molecule", first because the difference between classical and quantum physics when it comes to molecules is usually so minute we can't measure it, and second because it is precisely opposite of the way the brain works.
Nor do neuropeptides spring into existence- ever. There is no "neurochemical" that could be "a thought of fear" and the idea of a neurochemical is both wrong and misleading. But the biggest and most important problem in the first paragraph is the idiocy concerning the "transformation of non-matter into matter". First because quantum physics can't possibly do this with "neurochemicals", neuropeptides, neurons, or anything else relevant here and in fact this description is misleading in its entirety. It is true that fields in QFTs are described allowing for the ephemeral existence of particles. However, he's not talking about particles but things that are so much bigger its like comparing the size of the moon to that of the Sun.
Onto the next paragraph, where we find that this fake process happens everywhere in nature "except that we do not call it thinking." Why don't we do that? Because nothing described so far relates to thinking and nothing from what was said could (plus the little fact that we don't tend to find thinking in nature, only in living systems). Then there the "level of atoms", which somehow follows "predictable steps" despite the fact that most systems described in quantum physics are continuous (minor point) and they absolutely do not follow predictable steps. I am not even sure how to relate this to some quantum or particle theory.
And as this is my field "proper" I can't resist pointing out this passage:
"When you think the word rose, a large number of brain cells have to fire (no one knows how many, but let us say 1 million, which is probably absurdly small), but these cells don't get in touch with one another by passing a message from A to B to e, and so on, until all 1 million get the message. The thought just appears, suddenly localized in time and space, and with it, the brain's cells all change in sync. The perfect coordination of this thought-event and 1 million brain cells making neurotransmitters must have happened below the line." (the "line" being a reference to Newtonian mechanics, which was nonlinear and most complex, nonlinear systems are described using classical physics).
He's supposed to have a medical degree, and while that doesn't mean he's an expert in neuroscience an undergrad textbook would reveal how wrong this is. First because thoughts and cognitive processes in general don't arise from neural firing (that, actually, is the kind of misinformation you'd get from an undergrad textbook). Rather, information is conveyed through the rate and timing of spike trains that are constantly active, constantly changing, and which allow the formation of thoughts through inter- and intra-neural activity in already synchronized neuronal networks. Also, a key component of higher level cognition (from a neurobiological perspective) is the fact that sensorimotor regions encode modality specific information about concepts (even abstract concepts) and it is through the representation of such concepts/memories/etc. in modal-specific cortical regions as well as their connections with the PFC and frontal cortext that allow representations of some "thought" to exist and to be processed (the representation and processing are not really two different things, as there is much overlap). Nor are there any specific representations that correspond to any particular thought, concept, or feeling. Overlap here is absolutely essential, so there is no sudden "burst" of activity that constitutes some "thought-event" with "the brain's cells all chang[ing] in sync." This is just sensationalist crap.
Chopra goes on to describe this nonlinear nature of quantum mechanics, and indeed states that the "change from straight-line causes to U-shaped detours occurred when quantum physics was born." This isn't just wrong or misleading, but characterized the entirety of both classical and quantum mechanics incorrectly in a quite fundamental way. First, while such a simplified account of causation in classical physics might have been sufficient ~150 years ago, a major discovery in physics (and well beyond) to quantum mechanics was what is commonly referred to as "chaos theory". Classical physics permits circular causation, living systems appear to be closed to efficient causation in ways that have nothing to do with QM but do make Chopra's attempts to compare all of nature as one complete bunk in a rather elegant way, and finally quantum mechanics is linear.
That doesn't stop Chopra from going on with his U-shape diagram to represent the "basic quantum event", and then bringing this back to the brain:
"Like the thought and the neuropeptide, light cannot be a wave and a photon at the same time; it is either one or the other. Yet it is obvious that a tungsten light bulb doesn't enter another reality when you turn it down. Somehow, nature sets up its laws so that light can be either A or B, and both are kept inside the boundaries of the same reality by building in a transformation point."
Had he simply described light as somehow both a wave and a particle, he would be as bad as many science popularizers. In fact, wave-particle duality is a notion that textbooks refer to. The truth is that nothing is a particle but everything is wave-like yet becomes approximately particle like at even very, very small scales (and by "approximately", again I mean you can't actually measure the difference between a classical vs. quantum treatment). That would be bad enough, but he relates this nonsense back to the brain, and "the thought and the neuropeptide". This is why he doesn't use the standard simplification of wave-particle duality, because he can't pretend that a neuropeptide is a thought, so he deliberately inaccurately describes
even the already simplistic version of QM in order to talk about "thought" and the "neuropeptide" as somehow capable of being one or the other thanks to quantum physics.
I can tear apart this book and others as well as his talks by writing post after post after post because I constantly reach the limit, but I don't see why this doesn't suffice as it is an example of some of the better lies and distortions that he sells and packages in his commercialized "spirituality". It's somewhat funny and more than a little ridiculous when a company like Verizon introduces Quantum TV/Internet. But everybody knows they are a business and they're using buzzwords to sell their products. He does the same thing with
Quantum Healing, but in the guise of a scientists and guru and so that people can not receive the help they might need, learn lies, and pour money into his coffer.
