Like.
I don't think that this can be said in such a rigorous way. Yes, physicists use the bra-ket notation, and mathematicians usually use the... -
nomadreid replied to the thread I Elementary question about comparing notations of inner product.Thanks, fresh_42. I know that it's pure convention, but I am trying to understand the relations between the conventions. What is clear...

All expressions are additive in both arguments. Whether you consider the left one or the right one as a covector is a deliberate...

nomadreid replied to the thread I Elementary question about comparing notations of inner product.anuttarasammyak, thank you for pointing out that I should have made precise that I was referring to complex vector spaces. I have...

nomadreid posted the thread I Elementary question about comparing notations of inner product in Quantum Physics.First, I need to check that I have the 3 notations correct for an inner product in finite vector spaces over a complex field; v*...

nomadreid reacted to PeterDonis's post in the thread I Prof Mike Wiest's proposed link between quantum and consciousness with Like.
We won't know that for sure until we have a confirmed theory of quantum gravity. :wink:

Retaking this point. So basically the only idea here is that gravitational-based collapse is maybe not like the quantum mechanics we...

Oh right! It was the "quantum gravity" terminology that threw me off. Proving or disproving gravitational-based collapse does not mean...

I don't think the research program referred to is to use quantum gravity to explain the brain specifically. I think it is to use quantum...

Just for sake of everything, I am not equating noncomputablity with nondeterminism, I am saying that quantum computing does not give you...

Noncomputability is a different thing from nondeterminism. It's actually related to undecidability, as is seen in the halting problem...

This is what I find hand-wavy. It is well know that a classical computer can simulate anything a quantum computer can do (just in more...

It should be noted that there are plenty of others who disagree with this point of view. One of the most notable arguments against it...

It is not impossible that more years (decades?) of AI development will lead to conscious physical systems In which the underlying...
