Physics of a Compact Disk essays

Physics of a Compact Disk essays Compact discs are the most popular form of recorded musical entertainment. They have more memory than their vinyl predecessors as well as a smaller size. Compact discs are digitally recorded, unlike the analog-recorded tapes and LP records, so have a better sound quality. Because of the benefits of optically recorded compact discs, this form of musical technology has almost completely replaced vinyl records and cassette tapes. CDs are played optically by a compact disk player. Laser light beams read the binary codes encoded on the disk during recording, and the code is interpreted as sound or silence. The more binary numbers there are that are read as sound, the greater the intensity of the sound. The sound is transferred to the compact disc players sound system and the music is amplified through the speakers. Compact discs are digitally recorded using an optical recording system. Music, or sound, is recorded in analog form through a microphone placed near each instrument. The original sound signal is continuous and varies in pitch, or frequency, and volume. The microphone changes the air vibrations that correspond with analog sound waves into electronic signals. These signals are measured up to thousands of times per second and are changed to binary numbers which represent varying sounds. These binary numbers are digitally recorded and are sent as a stream of laser light pulses through a fiber to be read by a photodetector in the recording system. Each light pulse is read as a single bit of information. A binary 1 is recorded sound, and binary 0 is a pause or silence. The laser flashes encode digital information onto the light sensitive compact disc to record the digital information. When all of the necessary information is on the compact disc, it is placed in a chemical that s eals the digital information in the disc. Microscopic pits are left in th ...

Concerning as an Adjective

Concerning as an Adjective Concerning as an Adjective Concerning as an Adjective By Maeve Maddox If hearing the word concerning used as an adjective to mean â€Å"causing anxiety† gives you a chalkboard moment, you may as well get used to it. The usage has yet to make its way into all the dictionaries, but it has hit the mainstream and it won’t be turned back. For about 200 years, concerning has been functioning quite happily as a preposition to mean any of the following: regarding relating to with reference to referring to with regard to as regards with respect to respecting dealing with on the subject of in connection with re apropos of Supporters of the adjectival use of concerning point to the definition in the OED: â€Å"that gives cause for anxiety or distress.† The one citation given for this usage is from Pamela (1740), the overwrought epistolary novel by Samuel Richardson. Pamela is a virtuous young maidservant resisting the overtures of her employer. Here is the passage in which concerning means â€Å"anxiety-producing.† The words not in quotations belong to Pamela’s narration: â€Å"Well,† said he, â€Å"if you won’t eat with me, drink at least with me.† I drank two glasses by his over-persuasions, and said, â€Å"I am really ashamed of myself.† â€Å"Why, indeed,† said he, â€Å"my dear girl, I am not a very dreadful enemy, I hope! I cannot bear any thing that is the least concerning to you.† Elsewhere, Richardson uses concerning conventionally, as a preposition: â€Å"Mrs. Jewkes has directions concerning you.† I hope, whatever be your honour’s intention concerning her, you will not be long about it. Have mercy on me, and hear me, concerning that wicked woman’s usage of me. To perform a Google Ngram search, I used the phrase â€Å"very concerning† to get an idea of the adjectival use of concerning. The phrase is effectively flat-lined in American English until 1972; it begins to take off in the late 1980s. My guess is that political writers and other media manipulators rediscovered adjectival concerning as a useful euphemism for words that might frighten voters or consumers. Compare: Increased juvenile drug use is disturbing. Increased juvenile drug use is concerning. The possibility of more terroristic attacks is a cause for concern. The possibility of terroristic attacks is concerning. The rise in global temperatures is troubling. The rise in global temperatures is concerning. It seems to me that concerning has the effect of distancing a perceived threat by making it seem to be a matter to be watched, but perhaps not one to get too excited about for the present. Whatever the reasons for the current popularity of concerning as an adjective to describe anything that causes concern, it has certainly caught on in American speech. If you find yourself looking for an alternative, here’s a list of possibilities: alarming bothersome disquieting distressing disturbing nerve-racking perturbing scary troubling unsettling upsetting worrisome worrying Want to improve your English in five minutes a day?
