What is Communication: Definition and 323 Discussions
Communication (from Latin communicare, meaning "to share") is the act of developing meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions.
In Claude Shannon's and Warren Weaver's influential model, human communication was imagined to function like a telephone or telegraph. Accordingly, they conceptualized communication as involving discrete steps:
The formation of communicative motivation or reason.
Message composition (further internal or technical elaboration on what exactly to express).
Message encoding (for example, into digital data, written text, speech, pictures, gestures and so on).
Transmission of the encoded message as a sequence of signals using a specific channel or medium.
Noise sources such as natural forces and in some cases human activity (both intentional and accidental) begin influencing the quality of signals propagating from the sender to one or more receivers.
Reception of signals and reassembling of the encoded message from a sequence of received signals.
Decoding of the reassembled encoded message.
Interpretation and making sense of the presumed original message.These elements are now understood to be substantially overlapping and recursive activities rather than steps in a sequence. For example, communicative actions can commence before a communicator formulates a conscious attempt to do so, as in the case of phatics; likewise, communicators modify their intentions and formulations of a message in response to real-time feedback (e.g., a change in facial expression). Practices of decoding and interpretation are culturally enacted, not just by individuals (genre conventions, for instance, trigger anticipatory expectations for how a message is to be received), and receivers of any message operationalize their own frames of reference in interpretation.The scientific study of communication can be divided into:
Information theory which studies the quantification, storage, and communication of information in general;
Communication studies which concerns human communication;
Biosemiotics which examines communication in and between living organisms in general.
Biocommunication which exemplifies sign-mediated interactions in and between organisms of all domains of life, including viruses.The channel of communication can be visual, auditory, tactile/haptic (e.g. Braille or other physical means), olfactory, electromagnetic, or biochemical. Human communication is unique for its extensive use of abstract language. Development of civilization has been closely linked with progress in telecommunication.
Peer-reviewed journal articles are probably the most well known medium for scientific communication, but oral and/or graphically presented material can be just as important. How much importance was put on sound oral communication skills in your undergraduate or graduate careers? Were there...
In Mandel et Al's most famous experiment (Fig 6 at [URL]http://student.science.nus.edu.sg/~g0203645/Atomic%20Molecular%20and%20Optical%20Physics/Quantum%20effects%20in%20one-photon%20and%20two-photon%20interference.pdf) the signal beams from two coherent downconverters are observed to...
Hi,
I just found this on archive:

Has anyone heard of this and do you think it is a valid claim?
All u need is a reciecver and transmitter right? Then why can't a sumthing be sent brain to brain , when it runs on electrical impulses? I would liek to hear ur imagination run wild with this.
:smile: :smile:
imagine you have this hugely long rod. like a lightyear long. and there's a button on one side of the rod. you, on the other side, push the rod onto the button (as fast/s;pw as you want), conveying a signal to the other side, and basically sending information faster than light. what's wrong with...
Do you think a using a cellphone(just the necessary parts, not the whole body) for communication with a Micro Aerial Vehicle can work?
Will it be able to transmit a live video smoothly and handle the large amount of data transmission/sec?
If the video is constantly being downloaded on a...
11. What is the formula that relates the fundamental frequency of a wave in a string to harmonic?
12. What two factors determine the velocity of a wave in a string? Which one of these quantities is varied between the strings of a guitar to give different notes?
If anyone has a answer to...
I'm a high school student working on an extracurricular activity where I'm trying to design and build a radio system to function similar to that of a rc vehicles. However, I'm just getting started, and my knowledge is mostly in mechanical engineering. Where should I start? Thanks
As we all know, animal can communicate with each other with body language, sounds, etc. just like human. But does every animal of the same species communicate the same way? For example, are cats in different areas communicate the same way?
Dear group, recently I have written a paper on the possiblity of sending faster-than-light signals using entangled photons. I have shown it to several people and I have not yet received any feedback on it. I also sent a copy to arxiv.org but it was rejected and no reason was given. I am looking...
I was thinking of something:
Say we have pairs of entangled photons. Say we send these through a polarization filter. We can call the output "ones". Now, we separate the pairs into two streams (through two optic cables). We store one member of the pair (without measuring it) and send the...
Say I have a solid rod of steel and I push one end, does the other end move near instantaneously?
As an extreme, say I had a solid rod extending from two space stations very far apart, if I pushed the rod perfectly perpendicular to the face of the rod, would the time difference between when I...
1. What is the function of the dish?
Ans: It is to focus the weak signals so that to intensify them.
2. What wave property is suitable to describe the phenomenon happened in the dish?
Ans: Reflection.
3. If an antenna is to be placed in front of the dish, where it should be placed to get...
What are the Local operations and classical communication that i keep hearing about?
It arises in quantum teleporting. Though i know that to perform quantum teleporting you need a classical channel (a phone line, an e-mail, etc) and I guess that classical communication refers to that, I still...
Much work has been done into detecting potential signals from extra-terrestrials, but I want to discuss the more active approach of sending signals ourselves...
What attempts at such communications have we attempted ourselves? I remember hearing of attempts to broadcast radio waves into...
I had never really heard anything about this, and now that I am reading about it, I am finding the results convincing. (Although I am still only just starting to get my hands on the actual results themselves, so I can't be certain yet).
I am talking about work done on measuring the frequency...
In the 1970's, we utilized the Arecibo Radio Antenna to broadcast a message to the depths of space in the hopes of comming into contact with life beyond this world.
In 2003, we did the same thing, sending a methematical code to convey our thoughts to the universe around us. I begin this...
A Weird Idea
Greetings.
I have this idea, i know it is not really good (i already realized some of its weakness), but i thought i will put it here, since i believe that as it gets discussed (if it will) i might learn sth new.
Ok, my idea is like a new way to make world-wide communication...
Okay first off I am not even sure if I am in the right spot to post this ...If I am not Kerri could you please move it to the right spot??
I am learning something very valuable and I need some help! I am learning that communication between men and women are VERY different! The question is...
Is there a scientific explanation for being able to verbally communicate telepathically?
Example: Me.. being here in California, carrying on a conversation with *somebody* on the other side of the planet?
