Quoting Copyrighted Work

Quoting Copyrighted Work Quoting Copyrighted Work Quoting Copyrighted Work By Jacquelyn Landis One of the most common questions writers have is, how much of someone else’s work can you quote without securing reprint permission? Can you quote a stanza from a poem? A paragraph from a magazine article? A page from a novel? Unfortunately, the answer isn’t as clear as we might wish. It lies somewhere within the fair use doctrine of U.S. copyright law. The original intent of copyright law was to protect a writer’s work from someone else using and profiting from it. The framers of this law, however, didn’t want it to be so rigid that it prevented reasonable public use of copyrighted works. Hence, the fair use doctrine was written. In a nutshell, these are the factors you must consider when deciding whether it’s okay to quote without permission: 1. The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes. 2. The nature of the copyrighted work. 3. The amount and substantiality of the portion used in relation to the copyrighted work as a whole. 4. The effect of the use upon the potential market for, or value of, the copyrighted work. (U.S. Code, Title 17, Section 107) As you can see, these factors are not clearly defined. A common myth is that writers are free to use 400 words from a book, 50 words from an article, or two lines from a poem or song, and it constitutes fair use. This is not true. In reality, fair use can only be determined by the court. And if you’re already in court, you’re in trouble. Song lyrics are particularly troublesome as the music industry is aggressive about protecting songwriters. Typically, you need reprint permission to use even a single line from a song. What this means to writers is that you should always be mindful of the fair use doctrine and take great care to seek reprint permission if you have any doubt. Furthermore, anytime you quote from someone else’s work, be sure to properly attribute it. Want to improve your English in five minutes a day?

Examples of Chemical Suspensions

Examples of Chemical Suspensions In chemistry, a suspension is a mixture in which the solute particles- whether liquid or solid- do not dissolve. Most of the suspensions you encounter in everyday life consist of solid particles in liquids, but suspensions can also form from two liquids or even from a solid or liquid in a gas. One key way to identify a suspension is that the components typically separate over time. Mixing or shaking needs to occur to form a suspension. Given time, suspensions usually separate on their own. Mercury Shaken in Oil Mercury is a metallic element that is liquid at standard temperature and pressure. Because of its liquid properties, the element can be mixed with oil to produce a suspension. The mercury particles will disperse throughout the oil when the solution is shaken, but the particles will never dissolve. If left to sit, the two liquids will eventually separate. Oil Shaken in Water Water molecules, because of their polarity, are highly attracted to each other. They exhibit a stickiness that can be seen by slowly moving two water droplets toward each other. Oil molecules, on the other hand, are non-polar, or hydrophobic, which prevents them from joining together with water molecules. Oil shaken in water will produce a suspension as the oil particles are momentarily scattered. Left undisturbed, however, the two elements will separate from each other. Dust in Air Dust in the air is an example of a solid-gas suspension. Dust- tiny particles that include pollen, hair, dead skin cells, and other materials- is lifted by wind and ventilation systems and scattered throughout the air, producing a suspension. Because the particles of dust are solid, however, they will eventually return to earth and form a fine layer of sediment on the solid surfaces below. Soot in Air Soot- which takes the form of black smoke- is made up of carbon particles released through the combustion of coal and other carbon-rich energy sources. When it is first released, soot forms a solid-gas suspension in the air. This can be seen in fireplaces, power plants, and vehicles. Like dust in the air, soot eventually settles, blackening chimneys and other surfaces.
