Symbol

A symbol is something such as an object, picture, written word, sound, or particular mark that represents something else by association, resemblance, or convention. For example, a red octagon may be a symbol for "STOP". On maps, crossed sabres may indicate a battlefield. Numerals are symbols for numbers (amounts). All language consists of symbols. Personal names are symbols representing individuals.

Psychoanalysis and archetypes

Swiss psychoanalyst Carl Jung, who studied archetypes, proposed an alternative definition of symbol, distinguishing it from the term sign. In Jung's view, a sign stands for something known, as a word stands for its referent. He contrasted this with symbol, which he used to stand for something that is unknown and that cannot be made clear or precise. An example of a symbol in this sense isChrist as a symbol of the archetype called self. For example, written languages are composed of a variety of different symbols that create words. Through these written words, humans communicate with each other.Kenneth Burke described Homo sapiensas a "symbol-using, symbol making, and symbol misusing animal" to indicate that a person creates symbols in her or his life as well as misuses them. One example he uses to indicate his meaning behind symbol misuse is the story of a man who, when told a particular food item was whale blubber, could barely keep from throwing it up. Later, his friend discovered it was actually just a dumpling. But the man's reaction was a direct consequence of the symbol of "blubber" representing something inedible in his mind. In addition, the symbol of "blubber" for the man was created by him through various kinds of learning. Burke emphasizes that humans gain this type of learning that helps us create symbols by seeing various print sources, our life experiences, and symbols about the past.

Burke also goes on to describe symbols as also being derived from Sigmund Freud's work on condensation and displacement further stating that they are not just relevant to the theory of dreams, but also to "normal symbol systems". He says they are related through "substitution" where one word, phrase, or symbol is substituted for another in order to change the meaning. In other words, if a person does not understand a certain word or phrase, another person may substitute a synonym or symbol in order to get the meaning of the original word or phrase across. However, when faced with that new way of interpreting a specific symbol, a person may change their already formed ideas to incorporate the new information based on how the symbol is expressed to the person.

Etymology

The word symbol came to the English language by way of Middle English, from Old French, from Latin, from the Greekσ�μβολον (sýmbolon) from the root words συν- (syn-), meaning "together," and βολή (bolē), "a throw", having the approximate meaning of "to throw together", literally a "co-incidence", also "sign, ticket, or contract". The earliest attestation of the term is in the Homeric Hymn to Hermes where Hermes on seeing the tortoise exclaims σ�μβολον ἤδη μοι μέγ᾽ ὀνήσιμον "symbolon [symbol/sign/portent/encounter/chance find?] of joy to me!" before turning it into a lyre.

Role of context in symbolism

A symbol's meaning may be modified by various factors including popular usage, history, and contextual intent.

Historical meaning

This history of a symbol is one of many factors in determining a particular symbol's apparent meaning. Old symbols become reinterpreted, due perhaps to environmental changes. Consequently, symbols with emotive power carry problems analogous to false etymologies.

For example, the Rebel Flag of the American South predates the American Civil War. An early variant of the crossed bars resembled the Scottish Flag.

Juxtaposition

Juxtaposition further complicates the matter. Similar five–pointed stars might signify a law enforcement officer or a member of the armed services, depending the uniform.

Question:

Answers:The triangle is a 'Delta' style winding. Each line of the triangle represents a transformer winding between 2 phases of the 3-phase power lines. There is no 'ground' connection. .

Question:Hi. I need to buy a diesel generator to run my house on. We have to run at least 3 ACs at a time. The ACs consume roughly 1500W with a surge power of 4500W. Here's my question. If I get a 12KW rated generator, does that mean that each phase can only handle 4000 KW, therefore not even enough to start an AC? On the other hand if I have a single Phase 12KW generator, I'll be able to run 3-4 ACs. So is it better to have a single Phase rather than a 3 Phase? i was given this formula by a sales man KVA=SQRT3 X V X i Can you shed some light on this problem? Greetings from Iran

Answers:I highly doubt you need a 3 phase generator. I would bet your home is only wired for 2?

Question:I know that the voltage from phase to phase is 380V when line power (phase to neutral) is 220V, this means 220*sqrt(3)=380, but how you can prove this formula?

Answers:Prove it graphically. The three phases are 120 electrical degrees apart. Draw a line with a length of 220. Draw another line with a length of 220 so the two make a 120 angle between the two. Measure the length of the third side of the triangle. You'll find that it is 380. If you bisect the 120 angle, you'll have two right triangles with angles of 30, 60, and 90. See the proof in the attached link to derive the 3 factor.

Question:Does anyone know of a good website or a book that is the 'definitive' guide to 3 phase electricity? I know the common voltages, and most of the hardware that is used in the field. I want to get to the next level, for example understanding in main power transformers, or instrument transforms how to calculate voltage on phase to phase, phase to ground on Y and delta etc, a little on harmonics would be nice too. Thanks In Advance.

Answers:I would recommend the books below, which can provide you a comprehensive knowledge in power systems, including harmonics, transformers and so on. 1. Standard Handbook for Electrical Engineers 2. Power System Analysis Short-Circuit Load Flow and Harmonics 3. Harmonics and Power Systems 4. Power System Harmonics PS. You might download these books from some sites for free.
