exactly.. bypassing consciousness has its advantages : )
here's a riddle that i cant make sense of..
they say that photons doesnt experience space nor time. iow, in their own frame of reference, they are created and absorbed instantly, as if they never even existed. but how is this possible?
to be clear.. i dont care for the mathematical explanation, nor the standard explanation of reference frames, time dilation, and such. instead, im trying to understand it in terms of human experience.
so again.. if this is true.. a photon leaves point A and arrive at point B instantly, while passing all the distance in between, regardless to the length of travel (not teleporting). so how is it possible?
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers.
The Navier–Stokes existence and smoothness problem concerns the mathematical properties of solutions to the Navier–Stokes equations, a system of partial differential equations that describe the motion of a fluid in space. Solutions to the Navier–Stokes equations are used in many practical applications. However, theoretical understanding of the solutions to these equations is incomplete. In particular, solutions of the Navier–Stokes equations often include turbulence, which remains one of the greatest unsolved problems in physics, despite its immense importance in science and engineering.
So what do these unsolved problems have in common?
Solutions are sought that provide order to phenomenon that appears chaotic and random.
Mathematicians, Scientists both seek answers that are found in symmetry and order. Order can be proven to exist. Randomness can not. Hence, you'll never find them searching for chaos and disorder. It can't be defined in the 1st place. It's simply a slow process for the Scientist, to find the Order in everything. It can intuitively be known before all examples become proven.
Two great aspects of a unified theory of the Universe - the quantum aspect and the relativistic aspect - each depends on a constant that sets a limit. In quantum theory it is Planck's constant, which is very tiny but not zero. In relativity, it is the speed of light, which is very great but not infinite.
Plank's constant sets a lower limit to the size of energy transfer and the speed of light sets an upper limit to the speed of information transfer. The two are related. If Plank's constant were decreased, the speed of light would increase.
This information itself tells us the Universe is ordered and no true randomness exists.
It absolutely does not! You seem to be confusing two concepts that have scarcely any relationship.
True randomness is absolute unpredictability. Quantum physics provides unlimited examples of absolutely unpredictable future observations.
Elroch - You make claim the two concepts have scarely anything in common ?
Oh ... how wrong you are !
If Planck's constant is decreased, the speed of light would increase.
Understanding the relationship between the two concepts and how they are related forms the foundation of A TOE.
You should know better. Mathematics has many examples of equations with Planks constant on one side and the constant for light on the other. Both are constants, both set limits, and upper and lower on the properties of the Universe.
You say they have scarcely anything in common ? Well OK - so you'd similarly say the quantum world and the real world have nothing in common it seems. Maybe they don't and that's why unified theories appear unsolvable - but We know better.
"True randomness is absolute unpredictability. Quantum physics provides unlimited examples of absolutely unpredictable future observations". - Elroch
I dare say this is your own peculiar definition. Randomness really has nothing to do with the ability to predict events.
Examples of "future observations" ??? Now I know you've fallen out of your Rocker ! Quantum physics makes predictions, collapsing wave functions seem random ...
but absolute ? Can't be proven.

2. Derive the formula for the De Broglie wavelength.
3. Deduce whether the following Aristotleian syllogism is valid.
Zeus is an immortal god. Quantum immortality saves Schrodinger's cat. Therefore, if we shrank Zeus down to the subatomic scale, Zeus would save the feline.

I remember gittin held over in Sparks, NV back in the day. It was several days, but boy did I eat good. Can't remember how much I gambled though.
The machines are right in the next room to your dinner tables, if you get my drift.
For the past three years at least, I've been down to five bucks a week if you can believe it.

"True randomness is absolute unpredictability. Quantum physics provides unlimited examples of absolutely unpredictable future observations". - Elroch

With all due humility, I know this subject unusually well and my understanding is based on the state of the art. I got a distinction in the course on randomness by quantum physicist and author Valerio Scalani called "Unpredictable? Randomness, Chance and Free Will". I am not aware of anyone who got a higher grade. Carefully note the title, then look at the syllabus: https://www.classcentral.com/course/randomness-736
This video introduction to the course (3 minutes only) explains that the "intrinsic randomness" (same concept as "true randomness" or "absolute randomness" in the informal terms above) is about complete unpredictability, and is an inevitable feature of modern physics.
I seem to recall criticising your approach with the suggestion that a better definition of randomness might be "completely lacking pattern". I don't remember my exact words. Of course, that's an idealism. I accept that. In reality, patterns have to be recognised and the only way to recognise a pattern is through predictability, so unless I worded it differently, I do now accept that your definition, Elroch, is "more correct" than the one I attempted. I just realised suddenly, a minute ago. Now I'll listen to the video.
Sorry.
elroch: "True randomness is absolute unpredictability. Quantum physics provides unlimited examples of absolutely unpredictable future observations."
if you want to define true random in terms of unpredictability, its fine. but you'll have to forget about observations, because it's a fallacy. this sort of unpredictability stem from disruption in causality (if it even exist), and has nothing to do with observers. big difference
as for quantum, its not the physics that claim true randomness, its just some of the philosophical interpretations of it, and those are meaningless to the truth.
but because we already been thru that before, and i know that you understand this concept very well. i'd like to ask you a personal question if you don't mind..
do you understand why? i mean.. why do you keep making false statements despite understanding very well that they are false?

Silver, you're saying that there are two kinds of unpredictability? Is this supposed to be from an interpretative point of view? You seem to be saying that you cannot identify unpredictability through observation? Have I got you right? But you seem to be arguing that "disruption in causality, independently of observation, causes this apparent unpredictability".
You seem to have altered your stance somewhat. Do you not see that "disruption of causality" is an interpretational position which accepts the paradigm of "total causal relationships across the totality of causal, universal events".
So what you're saying isn't an argument surely? It's a statement of position, of course, but it doesn't do anything to support the position.

Ultimately, mankind is forced into interpretations because we are trying to use ourselves to look at ourselves and to compare ourselves with. Or we are trying to use the universe to look at the universe and to compare it with the universe.
We can only do this by adopting as many different "positions" and by using as many different ways of looking at things as we can and comparing results. That's a general case and I can't be bothered to do the hard work to come up with a good example of that. Elroch is better at that than me.
yes and no. its hard for me to put it in words, but i'll try..
you can say.. "photon behavior is unpredictable for an observer". that is true.
but if you say.. "photon behave unpredictably regardless to an observer". that's a subjective opinion and may or may not hold true. like i said.. big difference.
and btw, i have no problem with subjective people such as yourself, it is not for me to decide who is right and whos wrong. but if you claim to be objective and then make subjective statements, thats just bad news.
as for interpretations.. they are only required when we dont know the truth. once we know the truth, they become obsolete. it is what it is, and thats all to it : )
My subject is philosophy rather than physics, although physics was always my best subject at school. I'm extremely interested in psychology and ideas about our minds, so I'm reasonably at home discussing subjectivity and objectivity.
I should like to tell you that there is no such thing as absolute objectivity, for a very good reason.
Things that exist are just things that exist .... no more and no less. We understand about some of them and we don't about others and all of our understanding is via our ability to make observations which can be interpreted as evidence, which is as concrete as possible.
Thus, objectivity is merely the procedures we try to use to make evidence concrete and reliable, by adopting various systematic methods. Objectivity doesn't exist in and of itself unless we choose to call existence "objectivity", but the problem there is that objectivity always implies subject and object .... that is, perception of an object by a subject, which we try to make as all-encompassing and as accurate as possible. Without our observations of existence or reality, there's nothing to be objective about. Ultimately, we can never disassociate our understanding of reality, of physics or whatever, from some, small degree of subjectivity and of course, we can confidently say that our assessment of some things has a large degree of subjectivity to it, such as music.
You make a fundamental mistake, because EVERY assessment of what truth is, is ultimately subjective, because it's performed through us, the subject, assessing the world, which is the object. Therefore it's incorrect to distinguish in absolute terms between what we consider "objective" and "subjective".
Do you follow me? This is my field of expertise. It doesn't make me any less "objective" than you but it does enable me to shed false expectations.

i dont care about penrose who cares he made the impossible triangle big deal i canned even draw bruhhhhh he just mad impossible shapes brhu
Big deal? Penrose didn't fabricate the Penrose triangle; he and his psychiatrist-mathematician father popularised it. If you are to direct so much hatred to this glorious mathematical physicist, berate the necessary Swedish graphic artist, Reutersvärd. And good grief, the fruit in these impossible figures, you may be enticed to ask? Well, mathematicians are toiling away generating algorithms and formulas and the process of doing so has applications in computer vision. The Impossible Figure has applications in cognitive science.
From your tone and language expressed, you may have a tendency to enjoy video games more than all the members combined on this forum. Consequently, I've rummaged my rucksack for a glorious game to play. Actually, my rucksack shouldn't proceed to exist due to your hatred toward impossible figures. Play Momument Valley, it's a nifty alternative to your hatred and video games.
