So I've been reading about electron correlation in respect to Hartree Fock methods. Anyhow there's this very short paragraph which says the following "Dynamical correlation means electrons are instantaneously avoiding each other" and "Non dynamical correlation exists when degeneracy of electron configurations occur" with as an example a stretched H_2 bond.
Now, what on earth do they mean with this? I can't find proper information on this. Or maybe there are different names for this, so that I'm looking for the wrong thing? Can anyone help me out here?
I've been diving deep in to electronics recently and have been really enjoying reading this subreddit's topics so I'm confident you all are really smart and can help me come to a full understanding of this. If any of the following is wrong, please correct me. That's why I'm here.
I recently heard a saying - Volts push Amps through Ohms creating Watts , which I generally understand. But the relationship between the first 3 and Watts has been a little bit unclear to me, probably because it's not part of the Ohms law equation.
So I was wondering if the equation for Watts is V x I, is it telling me something about the speed of the electrons?
My understanding is that current, I, is measured as "Coulombs per second" which tells us something about how many electrons are travelling through the wire per second (a shit-ton). So then isn't the V, voltage, part of that equation telling us how quickly they are actually moving through the wire?
This would make sense to me because then I can picture the electrons as something that has some sort of a force, that if too strong (i.e. too many watts), could burn out a light bulb that works within a lower capacity of electron movement speed.
Am I cold, medium, warm? Please help.
Also, as a bonus, tell me if any of this differs with AC Voltage, because I think it might. I kept my question to DC specifically for starters because that all I'm working with and learning from right now.
Thank you!

I need about 5-8 participants, doing this for my sociology class to see a correlation between age and electronic usage. 8 questions in total and it shouldn't take long to finish.
Update: Got my data. Thanks to everyone who participated!

I am considering moving to a subdivision within a mile of the place. Semiconductor plants can potentially poison the environment around them.
Do you know of any health issues being reported in association with living in the close vicinity of this location?

Someone in Phil of Mind mentioned this article, here's a bad copy of it http://www.u.arizona.edu/~thorgan/papers/mind/IPandPI.htm THE INTENTIONALITY OF PHENOMENOLOGY AND THE PHENOMENOLOGY OF INTENTIONALITY
I'd been wondering why I hadn't connected the two enough until recently and that paper points out that they're been treated separately by different stands of academia. But they argue they are inseparable. What views are held here?
I'd been kinda accepting that qualia is just what it's like being a particular pattern of stuff in the universe. But, despite accepting that the brain patterns evolved because they connected senses to actions intelligently - so like running a model of the world - i feel confused at how my qualia are that model. Then I think no that's not confusing because it is a model of a world so why shouldn't the qualia be. Well because the neuronal networks are just being themselves, so their qualia should be of themselves? It's only the big picture of how it functions that means it's a model of a world. So qualia are shaped by the function not just what it's like to be? But how can an abstract function become a real qualia, really experienced?
Edit: the above might not seem to make sense if it seems that an experience of being in a body looking out & listening out etc is naturally what it's like to be us, from our point of view. But it's not what it's like to be inside a skull, I guess is the issue.

I was going through a folder of my notes/quotes I have saved and found this (see bottom quoted paragraphs). I genuinely can't remember if I wrote this or saved it from elsewhere. It's an interesting take on mental illness though. People use neural correlates and argue that these correlates are somehow evidence that the brain is generating thoughts, but this is ultimately an assumption. Correlation =/= causation in every circumstance. If our brain is a receiver, then it could in theory "receive" external thoughts from any form of consciousness capable of hijacking the transmission. It is strange when you consider that these INTRUSIVE thoughts we have go away when we stop reacting to them and giving them our attention.
I had one experience of psychosis in my life and it was all very bizarre. I was in a bad place in my life as a result of certain life events. To save you the boring sob story and cut a long story short, I hadn't slept for several days, combined with the stresses I guess triggered some sort of psychotic episode. Initially, when I started hearing voices they were very faint, like quiet whispers. They were so quiet it was hard to even tell they were voices. I decided to just brush it off as some sort of weird ambient noise that I never noticed before. I thought they would go away, but when they didn't, I strained my ears and this is when it got weird.
As I strained and listened more intently, these whispers seemed to be getting louder, until eventually, I was hearing full-blown voices speaking to me as clear and vivid as someone sitting right next to you. These voices were pure evil and seemed to react to my emotional state. The more fear I showed, the louder and more vile the contents of their speech seemed to get. It genuinely seemed that something external to my mind was reacting to my emotional state and attempting to trigger fear and self-hatred. The stuff they were saying to me was some of the most repulsive and hurtful things I have ever heard. Stuff that you can't even imagine saying to your worst enemy. It was as if some sort of algorithm was scanning my brain and then reinforcing anything that triggered the most fear.
The voices would say things and then test my reaction. If I didn't react, they would say something new. Sometimes they would even change into voices of people I recognized and loved, and repeat these same evil phrases. Even still, there was something artificial about these voices. The trial and error nature of the co

These surprising photoluminescence dynamics are directly correlated with tomographic structures.
Abstract
Cryogenic single‐particle photoluminescence (PL) spectroscopy has been used with great success to directly observe the heterogeneous photophysical states present in a population of luminescent particles. Cryogenic electron tomography provides complementary nanometer scale structural information to PL spectroscopy, but the two techniques have not been correlated due to technical challenges. Here, we present a method for correlating single‐particle information from these two powerful microscopy modalities. We simultaneously observe PL brightness, emission spectrum, and in‐plane excitation dipole orientation of CdSSe/ZnS quantum dots suspended in vitreous ice. Stable and fluctuating emitters were observed, as well as a surprising splitting of the PL spectrum into two bands with an average energy separation of 80 meV. In some cases, the onset of the splitting corresponded to changes in the in‐plane excitation dipole orientation. These dynamics were assigned to structures of individual quantum dots and the excitation dipoles were visualized in the context of structural features.
