Sympathy
Sympathy is the perception of, understanding of, and reaction to the distress or need of another life form. According to David Hume, this sympathetic concern is driven by a switch in viewpoint from a personal perspective to the perspective of another group or individual who is in need. Hume explained that this is the case because "the minds of all men are similar in their feelings and operations" and that "the motion of one communicates itself to the rest" so that as "affections readily pass from one person to another… they beget correspondent movements." Etymology The roots of the word ''sympathy'' are the Greek words ''sym'', which means "together", and '' pathos'', which refers to feeling or emotion. See '' sympathy § Etymology'' for more information. Distinctions between sympathy and related concepts The related word ''empathy'' is often used interchangeably with ''sympathy'', even though the terms now have different meanings. Dictionaries distinguish the two terms. Com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympathetic Detonation
A sympathetic detonation (SD, or SYDET), also called flash over or secondary/secondaries (explosion), is a detonation, usually unintended, of an explosive charge by a nearby explosion. Definition A sympathetic detonation is caused by a shock wave, or impact of primary or secondary blast fragments. The initiating explosive is called the donor explosive, the initiated one is known as the receptor explosive. In case of a chain detonation, a receptor explosive can become a donor one. The shock sensitivity, also called gap sensitivity, which influences the susceptibility to sympathetic detonations, can be measured by gap tests. If detonators with primary explosives are used, the shock wave of the initiating blast may set off the detonator and the attached charge. However even relatively insensitive explosives can be set off if their shock sensitivity is sufficient. Depending on the location, the shock wave can be transported by air, ground, or water. The process is probabilistic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympathetic Magic
Sympathetic magic, also known as imitative magic, is a type of magic based on imitation or correspondence. Similarity and contagion James George Frazer coined the term "sympathetic magic" in '' The Golden Bough'' (1889); Richard Andree, however, anticipated Frazer, writing of sympathy-enchantment ( de , Sympathie-Zauber) in his 1878 ''Ethnographische Parallelen und Vergleiche''. Frazer subcategorised sympathetic magic into two varieties: that relying on similarity, and that relying on contact or "contagion": Imitation Imitation involves using effigies, fetishes or poppets to affect the environment of people, or people themselves. Voodoo dolls are an example of fetishes used in this way: the practitioner uses a lock of hair on the doll to create a link (also known as a "taglock") between the doll and the donor of this lock of hair. In this way, that which happens to the doll will also happen to the person. Correspondence Correspondence is based on the idea that one can influ ...

Sympathetic Nervous System
The sympathetic nervous system (SNS) is one of the three divisions of the autonomic nervous system, the others being the parasympathetic nervous system and the enteric nervous system. The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system. The autonomic nervous system functions to regulate the body's unconscious actions. The sympathetic nervous system's primary process is to stimulate the body's fight or flight response. It is, however, constantly active at a basic level to maintain homeostasis. The sympathetic nervous system is described as being antagonistic to the parasympathetic nervous system which stimulates the body to "feed and breed" and to (then) "rest-and-digest". Structure There are two kinds of neurons involved in the transmission of any signal through the sympathetic system: pre-ganglionic and post-ganglionic. The shorter preganglionic neurons originate in the thoracolumbar division o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympathetic Resonance
Sympathetic resonance or sympathetic vibration is a harmonic phenomenon wherein a passive string or vibratory body responds to external vibrations to which it has a harmonic likeness. The classic example is demonstrated with two similarly-tuned tuning forks. When one fork is struck and held near the other, vibrations are induced in the unstruck fork, even though there is no physical contact between them. In similar fashion, strings will respond to the vibrations of a tuning fork when sufficient harmonic relations exist between them. The effect is most noticeable when the two bodies are tuned in unison or an octave apart (corresponding to the first and second harmonics, integer multiples of the inducing frequency), as there is the greatest similarity in vibrational frequency. Sympathetic resonance is an example of injection locking occurring between coupled oscillators, in this case coupled through vibrating air. In musical instruments, sympathetic resonance can produce both desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympathetic Strings
Sympathetic strings or resonance strings are auxiliary strings found on many Indian musical instruments, as well as some Western Baroque instruments and a variety of folk instruments. They are typically not played directly by the performer (except occasionally as an effect), only indirectly through the tones that are played on the main strings, based on the principle of sympathetic resonance. The resonance is most often heard when the fundamental frequency of the string is in unison or an octave lower or higher than the catalyst note, although it can occur for other intervals, such as a fifth, with less effect. Description Sympathetic strings are used to enhance the sound of an instrument. Some instruments have only a few sympathetic strings such as the Hardanger fiddle (pictured above right). Other instruments which have more include the sitar with 11-13 sympathetic strings and sarod with 15 sympathetic strings, and the sarangi, which has a total of 37 sympathetics. In Western ...
