Anyone know of a site or text that describes how to translate information from one space to another?e.g. from momentum, phase or hilbert space to 3d space.I'm not sure if this can strictly be done but I'm assuming it can. If the basic principle is expressable in the length of a post then feel...

(Not sure this belongs in philosophy, but the only other option seemed to be pseudo-science, and I don't like the sound of that. Before I start, I've got to admit, I�m not especially well-versed in any of the concepts this post concerns... I have only a passing familiarity with Chaos Theory...

Can electromagnetic fields hold information the way an electromagnetic wave can carry information such as a radiobroadcast?If they can, I know there's a small form of EM field created by individual particles - could these hold complex information too or would they be too small?How long to EM...

(Reposted). A gravitational black hole abhors a "naked" singularity, but allows it the observable property of charge with E-M field. Similarly, the horizon for "electronic black holes" limits what we may eventually know about the electromagnetic structure of a charged particle.An electronic...

I've been working on an information systems model of the universe for nearly 40 years. I'm not just another quack, I am really a scientist, though physics has been more of a hobby, I have extensive experience in computer science and group systems research and significant information physics...

Is it reasonable to operate under the assumption that the Lorentz transformations and thus the Special Theory of Relativity are special cases in that they are based on quantities which are completely resolvable in only three spatial dimensions ?Also, are there any particular branches of matrix...

A article about introverts in the March edition of the Atlantic monthly says the following:quote:Science has learned a good deal in recent years about the habits and requirements of introverts. It has even learned, by means of brain scans, that introverts process information differently from...

Poll Question:Did you hear it? Last saturday it was announced in the NYtimes ScienceTimes that Craig Venter (from the private company Celera) had used largely his own genome for the decoding of the master sequence...Do you think that the information should have stayed anonymous?~Monique~Choices...

Not so long ago, the talk of physicists changed significantly - the speed of light as a constant has been replaced by the speed of information as constant. And all this in the wake of numerous experiments that altered the speed of light.This somehow does not sound right to me. Does it mean that...

The Whole Universe and any forming her part including elementary particles possible to consider as complex system. The Atom of the chemical element keeps information on characteristic of this element. The Molecule (the more complex system) keeps information on characteristic material. In the...

I recently read Cesar Hidalgo’s 2015 book: “Why Information Grows”, which I heard about recently on Sean Carroll’s podcast (I like it). It’s mostly an economics book that derives its main ideas from how information underlies organization in the universe, as well as in economic dynamics. I like...

In the process of trying to understand holography I encountered a detail that I kind of knew before, but just now I realized I have no idea how it works, how is it even possible. I’m talking about a simple pinhole camera where supposedly no matter how tiny a hole is a beam of light would still...

Summary: Can the speed of information be faster than light? Say you had two people in space and they were 10 light years apart. Each person has a light bulb and battery connected to an electrical switch. Pressing the switch turns the light on, once it is released it springs back to the off...

In cosmology, we are using the Friedmann equations for the evolution of the universe. And we are using this equation a lot. $$\frac{H^2}{H_0^2} = \Omega_ma^{-3} + \Omega_{\Lambda} + \Omega_ra^{-4}$$ If we write ##a(t)## in terms of z, $$H(z) = H_0\sqrt{\Omega_m(1+z)^{3} + \Omega_{\Lambda} +...

As a Computer Programmer, it's hard to wrap my head around Quantum Entanglement and non locality being explained in the context of Classical Physics. In other words, if the universe at it's core is physical where does Quantum Entanglement fit within a physical picture of reality? There's been...

I am trying to investigate my doubts that reversible operations can model (or at least mimic) information copy process. For simple model I take two numbers ##A \neq B##. Now I can't copy value of A into B without erasing (irreversibly) value of B. However I can use transformation that replaces...

Hello, my name is Jack and I'm a year 11 student in Australia. After listening to, and reading some information regarding quantum entanglement, I'm still a little unsure about the solution to a thought experiment: Let's say that I create a situation in which multiple pairs of particles are...

Hi, I want to change the header of some document files like pdf, ms word, libre office programatically. I know that I have to use some byte type command like putc(..) and getc(). But I don't the header size of the above mentioned file formats.I saw a list of file format at wikipedia...

I can't seem to wrap my head around the notion of conservation of quantum information. One thing that might help that is if someone can tell me what the associated symmetry is. For example, phase symmetry leads to conservation of electric charge according to Noether's theorem; a fact that...

Anybody know more about this? It is in DISCUSSION forums since I do not see any decent references on the subject. Maybe I'm having a bad day... ##SF_{6}## - Prevents fires from electrical shorts, used in high kVa distribution lines - at connection points, substations, and "ties" Apparently...

Suppose I fire a photon with an upward spin towards a hydrogen atom. It is absorbed by the hydrogen atom's electron which subsequently emits a photon when it returns to its ground state. I then fire another photon with a downward spin towards the same hydrogen atom and the same thing happens...

I am 3rd year physics student (actually I have just finished it). I have good knowledge on basics of quantum mechanics: I had 1 semester of Introduction to Quantum Physics and then 2 semesters of Quantum Physics. Our literature were Griffiths (Introduction to Quantum Mechanics) and ''Gennaro...

I just wandering about the following hypotetical process to get some information from the inside of a black hole. 1. Drop a satellite into the black hole on a nearly tangential orbit. 2. After it crossed the event horizon drop a large mass after it (for example a small black hole). 3. This mass...

I'm sure that many PF members are fans of the seminal book The Visual Display of Quantitative Information by Edward R. Tufte But books on dead trees can only show static information. How about quanitative information depicted with the help of audio and/or video? I would like to nominate...

Did physicist John Archibald Wheeler propose the existence of multiple universes through his "It from Bit" or "Participatory Universe Principle" or "Law without Law and Pregeometry"? Is the multiverse related to Wheeler's ideas? I've been told that It can produce multiple universes, obviously...

In the context of a forecast, I am currently working on Fisher's formalism which is part of a more general theory, that of information. My problem applies to estimating cosmological parameters from input data with the Fisher formalism and recipes to build a Fisher matrix. The context is...

So I started from the heat governing equation above. There is no heat generation or matter flow, so I simplified it to dT/dt = A d^(2)T/dx^(2). Now I assume dT/dt = (278.15K-277.38K)/(1200s-900s) = 0.0025667. But then I'm stuck with the d^(2)T/dx^(2). Is the x just 0.20 m? For T I used 288.15K...

I have been asked to draft a (informal) research proposal for a PhD thesis. I have some background in quantum information and my interests are leaning towards the AdS/CFT correspondence. I was wondering if you could suggest a few (preferably recent) theory papers at the junction of quantum...

It seems that the way to combine the information given is z = f ( g ( (3r^3 - s^2), (re^s) ) ) we know that the multi-variable chain rule is (dz/dr) = (dz/dx)* dx/dr + (dz/dy)*dy/dr and (dz/ds) = (dz/dx)* dx/ds + (dz/dy)*dy/ds ---(Parentheses indicate partial derivative) other perhaps...

I am looking for information on a supposed prompt supercriticality event that occurred at ORNL while the MSRE reactor was running under Syd Ball. This incident was told to me by an engineer that is actively involved in reigniting interest in MSR based reactors. According to his summary, "Syd...

Other than with black holes, are there any other natural ways that quantum information can be lost, and thus jeopardize quantum determinism?

Hi everyone, initially let me introduce a concept widely used in ARIMA in the following. $$AICc = AIC + \frac {2k^2+2k} {n-k-1}$$ where n denotes the sample size and k denotes the number of parameters. Thus, AICc is essentially AIC with an extra penalty term for the number of parameters. Note...

The brain receives a lot of visual information some of which is redundant visual information. I am imagining it like the brain receiving a 1000 pixel wide by 1000 tall image of a road. The brain has received 1,000,000 bits/pixels of information. I am assuming the brain doesn't need all that...

Hi everyone, while I was digging arima model I saw that BIC value is given as $k*log(n)-2*log(L)$ where $L$ is the maximized value of likelihood function whereas $k$ is number of parameters. I have found the proof of AIC but no any clue about that. I wonder how it is derived. Could you help me...

I am a master student in theoretical physics from Italy and I would like to know more about fields related to "Quantum Information". I've been to some seminars and I think that these fields are very interesting, but I need to understand before applying for a PhD. What should I do?

Both the heat equation and the diffusion equation describe processes which are irreversible, because the equations have an odd time derivative. But how can these equations describe the real world when we know that all processes in nature are reversible, information is always conserved? But these...

Hello everyone! I would like to ask a rather comprehensive question. I would appreciate it if you could help me with this. I have started reading a chemistry textbook recently and typically in the first chapter of any basic chemistry course, you come across, measurement, unit conversion, etc...

Hello all: I need to ask this rocky question, if you want some funding for a research project and you are outside academic sphere currently , how to get it ? Where to apply ? And how to find team member, considering the project is a short one ? What about patents ? Best H

Is the problem with interpretations of quantum mechanics that one can describe the universe consisting of "stuff" that exists ontologically in different but conflicting ways, so that the universe can really only be described informationally instead of ontologically? That is: does the universe...

I have only recently started studying information theory and I am stuck even trying to understand the basic problem and concept of information theory. My question is why does information need a probability? I have read some text that starts by introducing the idea that the amount of information...

There are two aspects of uncertainty (a) how far different from the situation where all possibilities are of equal probability (b) how spread out the values are. In discussions about (Shannon) entropy and information, the first aspect is emphasized, whereas in discussions about the standard...

If they could solve the information loss paradox in black hole https://en.wikipedia.org/wiki/Black_hole_information_paradox What other related problems it could solve in Beyond Standard Models or unsolved quantum questions, etc.? If the LHC could no longer detect new particles, could beyond...

More specfically can time be defined as information being passed from particle to particle?

Hi all, I don’t know if posts like this are allowed and if not mods please remove but I am currently enrolled in Gen Physics 1 w/Calc(I don't know why I challenged myself with this class when normal Physics 1 would’ve worked for me as a biochem major) and am struggling to do understand the...

Hi, I’m interested in self studying so that I can learn / understand integrated information theory about counciousness. I was wondering if anyone could help me identify what courses (I’m looking at using MIT’s opencourseware to study although just types of math is all that is needed) I would...

So I have been trying to derive peukerts exponent based on assumptions I know this won't be accurate but I am curious about the data. So I don't know the time to discharge the battery so I guessed 3 Hours the capacity at a 20 hour rate is 40Ah meaning the manufacturer rated discharge current was...

Could information in a boundary be modified once encoded in holographic principle?There are models of universes where holographic principle has a different correspondence (there is absolutely no reason to assume that this would hold true for all possible universes. You could have a universe...

If this is not in the correct area please move it as I am not sure. Also the same with the prefix. I have searched this on the forum and could not find anything relating to it. https://phys.org/news/2018-09-scientists-mechanism-storage-atom.html
