Diagnostic Medicine X-Rays, Hi essays Diagnostic Medicine X-Rays, History, Uses X-ray technology has developed over the past hundred years into a vital technology used in our everyday lives. The mysterious origins of the X-ray date back to the turn of the 19th century when German physicist, Wilhelm Conrad Rntgen stumbled upon this technology. X-ray technology has helped airport security s scan luggage, aid physicists in the study of atomic and molecular structure, and has helped astronomers investigate the astrophysical universe. It has proved invaluable in the fields of astronomy, defense, security, maintenance, and inspection. However, in this report I will focus on the X-rays role in medical diagnostics. In 1895 Wilhelm Conrad Rntgen discovered a light wave capable of penetrating certain mediums and allowing an inside look at the human body. Wilhelm, a German professor of physics was performing independent experiments with vacuum tubes and cathode rays, when he happened to notice an object across the room glowing when his cardboard-shrouded tube was charged. Next, he tested paper, wood and aluminum and noticed the same effect. Professor Rntgen realized these rays were invisible electro-magnetic rays, capable of making certain materials glow through his cardboard box and wooden door. He exposed a myriad of objects to these rays, including his weight box, a wire coil and even his gun. Rntgen realized the potential significance of his discovery, and confided in a friend, "I have discovered something interesting, but I do not know whether or not my observations are correct." His prophesy came to fruition one week later when an X-ray photograph of his wifes hand clearly showed her bones and wedding ring. Ecstatic, Rntgen forwarded his report to the president of the Wurzburg Physical-Medical Society. Accompanying his written report he enclosed experimental radiographs and the X-ray image...

Quote vs. Quotation, Invite vs. Invitation

Quote vs. Quotation, Invite vs. Invitation Quote vs. Quotation, Invite vs. Invitation Quote vs. Quotation, Invite vs. Invitation By Maeve Maddox One of my college professors insisted that quote is a verb and quotation is a noun and never the twain shall meet. For example, a writer quotes from an author, but the quoted material is a quotation, never â€Å"a quote.† Although I still observe the distinction in my own writing, I have become aware that both the OED and Merriam-Webster recognize the use of quote as a noun. Most English words ending in -tion have French cognates, for example: information, confirmation, and position. Such words came into English in the Middle Ages from French. In M.E. the ending of these French borrowings was spelled -cioun; later the ending came to be spelled -tion in both languages. Through the centuries, many -tion words have lost their endings, and more are in the process of doing so. English words ending in -tion tend to lose the suffix when the first part of the word retains the word’s meaning without it. Here are some shortened -tion nouns that have become accepted into standard English: quote from quotation ID or I.D. from identification insert from insertion Here are some that the OED still labels colloquial or slang: invite from invitation info from information admin from administration prep from preparation promo from promotion (in the sense of publicity) ammo from ammunition NOTE: M-W does not agree with OED on all of the shortened -tion words. For example, while M-W labels the noun invite â€Å"chiefly dialectal,† it admits ammo as a standard word. OED does not have an entry for specs with the meaning specifications, but M-W has. Many speakers cringe when they hear or read invite used as a noun, but the tendency to drop -tion when the rest of the word is sufficiently meaningful without it, is strong in English. I may not like hearing invite used as a noun, but enough speakers use it that way for it to make a comeback. Yes, comeback: 1659  Ã‚   H. LEstrange Alliance Divine Offices 326  Ã‚   Bishop Cranmer..gives him an earnest invite to England. OED documentation. A second tendency with -tion words that I find it difficult to accept with equanimity concerns verbs. The function of the suffix -tion is to change a verb into a noun: examine/examination, locate/location, converse/conversation, interpret/interpretation. Some speakers, however, perhaps because they are not familiar with the underlying verb, create a new verb via back formation. For these speakers, orientation become orientate; interpretation becomes interpretate, and conversation becomes conversate. NOTE: Back-formation is the formation of what looks like a root-word from an already existing word which might be (but is not) a derivative of the former. Of the words I just listed, orientate has become standard in British English, but it is still regarded as nonstandard in American English. Interpretate does appear in the OED, but it is labelled â€Å"rare or obsolete†; the most recent example of its use is dated 1866. Want to improve your English in five minutes a day?
