Similar Phenomena
Other phenomena have similar symptoms to ringing, but are otherwise distinct in their causes. In cases where these cause circular artifacts around point sources, these may be referred to as "rings" due to the round shape (formally, an annulus), which is unrelated to the "ringing" (oscillatory decay) frequency phenomenon discussed on this page.

Famous quotes containing the words similar and/or phenomena:
“The history of all Magazines shows plainly that those which have attained celebrity were indebted for it to articles similar in natureto Berenice—although, I grant you, far superior in style and execution. I say similar in nature. You ask me in what does this nature consist? In the ludicrous heightened into the grotesque: the fearful coloured into the horrible: the witty exaggerated into the burlesque: the singular wrought out into the strange and mystical.”
—Edgar Allan Poe (1809–1849)
“There are no moral phenomena at all, but only a moral interpretation of phenomena.”
—Friedrich Nietzsche (1844–1900)
