We all talk about other matters, before that lets talk about ourselves.
We already have a "Random thoughts' thread. What subject, specifically, did you want to discuss, and why, and if it has to do with science, we will need appropriate sources, you should read the forum rules first if you are not sure what those are.
I just need to know about human mind. From a physicist's point of view, that's all
If I crossed any sort of forum rule, I apologize.
You might read something by Fritjof Capra. But other people here may not like him. It may be against the rules to talk about physics - consciousness relationship here. I'd love to hear what other members think but I'm afraid it may be banned.
I agree here with Evo, who is being sympathetic to your cause, but you need to be more specific and phrase your question in a manner that can be addressed more scientifically.
A starting place could be Francis Crick's The Astonishing Hypothesis. I found it a worth while read but not astonishing. The emergent theory of consciousness is also worth looking at. I am skeptical but not dismissive. I would appreciate a book recommendation on that.
I might not go so far as "dissuade" someone from reading "The Astonishing Hypothesis," but I'll give you my opinion. Francis Crick knows (knew) next to nothing about how the brain works, and Christof Koch doesn't know much either. I never met Crick, but I had dinner with Koch and his sycophant girlfriend at the time and it was a nauseating experience. This guy (Koch) has a tattoo of the apple computer logo on his shoulder, which exemplifies what a moron he is. As far a Crick, I'm not impressed with him either. I think the evidence is clear that it was James Watson that cracked the code of DNA, Crick just happened to be along for the ride.
In truth it's the only book I've read on the mechanistic view. Care to recommend a better one?
Yeah, I can recommend a great book, for what it is you want to know...It's called the King James version of the holy bible! Just kidding. It's called "Going inside: a tour round a single moment of consciousness," by John McCrone. This is a great book. Even though it was published in 2000, the concepts in this book transcend decades. It still holds up. The most important part of it is that it gives you a history of of the nightmare of errors that it took us cognitive neuroscientists to arrive at where we are. And for me, this is the most important thing about science, it's being able to identify with the history of thought and the social contect of the characters/players that advanced the state of the art (of the science) over the decades. It's not just about shutting up and calculating.
And, even if he did, how the brain works is only indirectly connected to how the mind works. The brain, as hardware, can accommodate such a huge variety of what we conceive of as mind that a physics understanding of mind is a pointless thing to shoot for. Getting traction on mind is generally tackled at the level of psychology; very far away from physics.
If you have some background in neuroanatomy and want something more current, I'd recommend Swanson's great book, recently updated in 2014, Brain architecture: understanding the basic plan. This is the real deal, but not for the faint of heart.

Thanks, it's on order. But its a bit creepy that you can divine "what I want to know" from that post.
"... It's not just about shutting up and calculating..." And why is that? Unreality in the global in the zeitgeist, self deception, tacit assumptions/axioms? Or do I miss the point?
As only a distant observer I get the impression that philosophy, neurology and empirical psychology seem to be coming together in constructive ways. It makes me hopeful.
There is a growing number of researcher that think physics can significantly contribute to the understanding of brain and other complex biological structures.
And most recently a Commentary in Physics Today "New mathematical physics needed for the life sciences" calls for the education of physicists in the intricacies of the life sciences including neuroscience.

Today's SMBC. Hee hee.
But you're missing my point. Brain and mind are two different things. How the brain works, might, indeed, be traced lower and lower to the underlying physics. That which we call mind happens at a completely different level. It's the difference between computer hardware and what gets programmed into the computer. You look at the program at the level of programming. I have a Mac, but I can install Windows on it if I want. Mind is about the difference between OS X and Windows. The physics of the hardware doesn't give you much insight into the differences between those two operating systems.
i know very little about neuroscience but I don't think your analogy is that good . From the moment of birth we are accumulating data and organizing it. The brain must come with a sort of BIOS It must come with some sort of "firmware" which must be intrinsic to the physical nature of the brain. So I am saying that the mind is in part a reflection of the biophysical structure of the brain and you cannot definitively separate them. We see that drug for example can create psychosis and well as treat (ameliorate) it. Changing the biochemical environment can affect the mind. Hormone affect the mind. We all have unique personalities It seems more and more we find structure and function intertwined.
Yes, I agree that a computer to brain analogy is not that good, and, yes, mind arises from the activity of the brain, but the things we speak of as properties of the mind have much less to do with the physics underlying it all than with a particular mind's history and training. Why is a particular person afraid of spiders but not of heights? Why does he like red but not yellow? Why is one person chronically late while another is chronically early?
Neuroscience can study, as an example, the neuronal train of events when someone experiences anxiety, but psychology studies the emotional train of events whereby something (like a spider) might evoke anxiety. "Mind" is a psychological concept and 'the workings of the mind' are psychological considerations. Asking what we know about the mind is a different question than asking what we know about the brain. The emphasis is totally different.
