Maybe its not clear what interaction is? Its what we observe as mutual exchange of energy, within all of the conservation laws.-- Physical entity and imaginary entity cannot interact. They are incompatible.
Why?! You cannot have an imaginary entity, without there first having been a physical interation in the brain.
When you try to imagine nuclear explosion in your head, I'm sure you can get the image. But when you get that image, I'm sure you hometown will not get blown away.. Your imagination does not have influence to not a single atom in your body, its a shadow. Its not even clear what we perceive as thought. But one thing is clear, our thought image can be larger than our brain, it exists in our mind for short time, and is recycled into other thought that engages same amount of neurons, but is magnitudes smaller in any conceptual respect (yet may have more influence on our body, like reverting from concept of infinities to a concept of tits).
something forms what we know as quants. Quants form what we know as atoms, atoms form molecules, molecules form chemistry, materials, that form solid and other bodies, bodies form celestrial bodies, they form star systems, galaxies, etc. These examples of abstractions. But they have corresponding physical systems. To say that 1 hydrogen atom interacts with what you call car is nonsense. Or that your car interacts with galaxy. Atom can interact at atom level only, and car at mechanical level.-- Imaginary entities at different levels of abstraction cannot interact.
Why not? I also really don't get what "different levels of abstraction" means.
Yes, but not the opposite. Our brain can perfectly exist without our marvellous conceptual mind. Concepts you imagine do not exchange energy with your neurons. Its only neurons that exhange energy.But why? Without the physical (brain) interacting with the conceptual (mind), science could not exist, because we would be unable to ponder anything.
Shadow of an object does not exchange energy with that object, they don't interact. Shadow is not physical entity, its something else, illusion perhaps. Our mind is able to create those shadows and observe them. That does not make shadows physical.
Water is concept, that has corresponding physical entity. Triangle is concept, that does NOT have corresponding physical entity. Bermuda triangle does have physical entity. How would you make abstract idea to exchange energy with physical entity??It can in my (conceptual) mind. Besides, water isn't a concept - it is a physical entity. Subatomic physical things interact a certain way, to produce more advanced physical entities.
Did I mention photons? I include all that can exchange energy within laws of conservation. I try to see them in anterior-posterior hierarchy, and judge what are compatible concepts for interaction. Trying to forcibly mate incompatible concepts can lead to weird results, and getting stuck with progress.Another thing I wonder about: Why is it that you include theoretical particles, such as photons, in your list of "real physical things"?
There is something wrong at quantum level with our theories. If not anything else, then they are way too complex for levels more fundamental than molecules. Maybe its result of mating incompatible concepts, and missing some intermediate abstractions.
No, I don't want equations unless they seem important. But I'd like to understand how 1D lines can be physical. I can understand ropes, but 1D lines?BTW, we could discuss equations if you wanted to, but I don't see how it clears much up, except for the fact that 1D entities can be physical.
