Evanescence and permanenceThe words 'Evanescence' and 'permanence" are actually opposite meaning or antonyms.
There are many things around us which we enjoy greatly and wish they remained so permanently or at least for some more time. Such things which appear and stay only for a very short time before gradually disappearing or vanishing are called Evanescent. The word can mean - short lived, momentary, fleeting, ephemeral, transient etc .etc.
However the word evanescent is not much used now except as a decorative word or in poetic and philosophical contexts.
Following examples of some interesting things that we are familiar, can give us the refined precise meaning of the word ; viz. the evanescence of a rainbow; the evanescence of the ocean waves; the evanescent flash of a meteor; the evanescent morning dew vanishing under the rising Sun; etc.etc.
To illustrate further I may add that New Year Resolutions of most people turn out to be evanescent events.Speaking philosophically, in comparison to the Cosmic time period, human life is just evanescent.
The term is used in the context of Electromagnetism as 'evanescent waves' which are electromagnetic waves that do not propagate and are concentrated in the vicinity of the source. In the context of Optics and Acoustics, 'evanescent waves' are formed when waves undergo total internal reflection at boundary of a medium.
I would like to share here an interesting news headline which used the words evanescence and permanence in the same sentence." Evanescence singer Amy Lee has confirmed to Australia's undercover news that Cold guitarist Terry Balsamo is now a permanent member in Evanescence"(blabbermouth.net dated January 16,2004)
"Permanent in Evanescence" how can it be? It can be, because in the above quoted headline Evanescence denotes the name of an American Rock Band started in 1995.
I hope this thread will stay permanent in the server space and not vanish as in an evanescent flash.
