==Description==
'''Ephemeral''' things (from [[Greek]] εφήμερος – ''ephemeros'', [[literally]] "lasting only one day") are transitory, existing only briefly. Typically the term is used to describe objects found in [[nature]], although it can describe a wide range of things.

Often [[happiness]] is described as being ''ephemeral'', as one does not find it to be a permanent state, within the scope of [[human]] lives. There are always varying shades of happiness and [[disappointment]].

In computer networking [[technology]], an [http://en.wikipedia.org/wiki/Ephemeral_port ephemeral port] is a TCP, UDP or SCTP port which is [[dynamically]] assigned to a client application for a short period of time (the duration of time the application is running). This is in [[contrast]] to the "well known" ports which are typically statically assigned to a specific application or service.

In [[philosophy]], [http://en.wikipedia.org/wiki/Denis_Diderot Denis Diderot] makes use of the term "Fallacy of the Ephemeral," which refers to [[assumptions]] made outside of one's scope of [[time]], [[perception]], or [[knowledge]]. "...in the [[memory]] of a rose no one had ever seen a gardener die". From Diderot's ''[http://en.wikipedia.org/wiki/Le_r%C3%AAve_de_D%27Alembert Le rêve de D'Alembert]''.[http://en.wikipedia.org/wiki/Ephemeral]
