Regarding the conservation of information, what is the law of conservation of information? How is in

Esoteric This question requires physicists.

The first law of information, also known as the law of conservation of information, refers to:"The change in the information stored in the system is equal to the information entering the system minus the information leaving the system", that is, the change of information stored in the system = information entering the system - information leaving the system. It is represented by the formula δ nu= nq-nw. This formula corresponds to the previous one (change in information stored in the system = information entering the system - information leaving the system).

<> you've all heard of the law of conservation of energy.

That's right. Anyone who has taken a high school physics class has surely learned this law, which says that in a closed system, the total energy is constant. In fact, the law of conservation is not only the conservation of energy, but also the conservation of matter and the conservation of information, and that's what we're talking about here.

Similar to the law of conservation of energy, the law of conservation of information says that information cannot be destroyed. The information itself does not arise in a vacuum, so it does not disappear in a vacuum, but the state of the information may change. The law of conservation of information is quantum mechanics.

It is one of the fundamental laws of quantum mechanics and the iron law of physics.

You've got a piece of paper with a message on it, and now we're going to try to tear this piece of paper off and burn it and it'll float in the air like a pile of dust. Wouldn't that information disappear? Otherwise, according to the law of conservation of information, information does not disappear, but changes in form.

Figuratively speaking, the information is now a pile of dust floating in the air and cannot be found. So the question is, what is the meaning of information in this form? We can no longer read the content of the message, so doesn't that mean the information is gone?

Do a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The law of information constancy refers to the fact that the change of the information stored in the system is equal to the information entering the system minus the information leaving the system, and the information can be changed from one state to another state without disappearing.

This is a very important law in the scientific community, there is a conflict between matter and matter in the conservation and unity of force, and then the matter sucked in by the black hole will be released at the same time with imitation leakage; The total information flowing into the system will be equal to the information flowing out of the system, and the information can be transformed.

The law of conservation of information refers to the change of information in the system, the information that enters the system sensitively, and the information that leaves the system; Information is not generated in a vacuum, and it is known that the situation will not disappear and break in a vacuum, but the state will change.

The new definition of information dy, the standard logic of "attribute + difference" dy.

deng'Definition of New Information for Transformation (Creation) Information is information, and information is the marking of matter, energy, and information.

The concept of "information" proposed by Deng Yu defines the essence of information as "information is a collection of things and their attributes".

Inverse of Shannon's Information Definition: Replace the famous "information definition" of Wiener and Shannon with "affirmative" to become the inverse 1 of Shannon's information definition - the inverse definition of Shannon's information definition 1:

Information is an increase in certainty.

or Shannon Information Inverse Definition 2:

Information is something that confirms certainty (certainty). or The information is a positive confirmation.

Corresponding formulas. ir=-logpi+1 or.

ir‘=log((n-ni)/n)=log(nq/n)=logpq

That is, the information of early immortal farmers is transformed from the uncertainty of negative entropy in the form to the positive entropy in the form to supplement this - certainty. See the original negative Shannon definition of information: information is something that eliminates random indeterminacy. Formula.

i=-logpi=-log((ni)/n) =logni-logn)=logn-log ni

log((n-nq)/n)=1-1- logpi=1-(1+ logpi)=(1- logpi) –1

Wiener information definition inverse: information is the logo of matter, energy, and information (marking, representation, table number, representation, signal, label, representation, identification). or "information is a logo that accompanies matter, energy, information and attributes"; Or "Information is information, the identification (representation、...... of matter, energy, and information

The miniature of Zhong Yixin's definition: Information is the way things change their state.

On July 21, 2004, at the "17th International Congress on General Relativity and Gravitation" held in Dublin, Ireland, the legendary British scientist Professor Stephen Hawking announced the results of his latest research on cosmic black holes, and Hawking's attitude took a 180-degree turn, saying that his original view was wrong, and that information should be conserved: black holes are not "completely devoured" by everything around them, as he and most other physicists previously believed. In fact, some information about the matter that is sucked into the depths of the black hole may actually be released at some point: the conservation of information.

deng'S Fundamental Procedure for Conservation of Information (Deng et al., 2005, published in the journal Chinese New Medicine).

nq=nu+nw

dnu=dnq-dnw The total information flowing into the system must be equal to the total information flowing out of the system, plus the changes in the internal information of the system; Information can be transformed, from one state to another; Information can be created and it can be lost. It is expressed by the formula as.

nq = nw +δnu like Deng Yu's new definition of the concept of "Conservation of Information: N = Ni" (definition of law)2:

The law of conservation of information states that "the increase in the information stored in the system is equal to the information entering the system minus the information leaving the system".

nu= nq-nw

Changes in information stored in the system = information entering the system - information leaving the system.

Newly created information - information that is lost ('disappeared' to leave).

The definition of the occurrence of the 'concept of conservation of information' that can be created and can be lost" is transformed from "the change of information in the system = the information entering the system - the information leaving the system" to the "(information) can be created and can be lost".

The change of information in the system is equal to the newly created information entering the system minus the information lost (leaving, dissipating, disappearing, extinguishing) of the system. It is the unique attribute and essential connotation of the law of conservation of information transformation: the original expression formula of "information can be created and can be lost".

Changes in the information stored in the system = newly created information Lost information.

nu = NCRE NLOS Law of Conservation of Information or Conservation of Total State, formula:

n=∑niorω=∑ωi i=∑ii

Derivation of "conservation of entropy": s= si generalized information conservation, etc.
