Free Essays on Classical And Romantic Music

Prior to the twentieth century when jazz, blues, country, and rock and roll music entered the scene, almost all music was what we called â€Å"classical music.† From the 1700’s to the 1900’s classical music composed for orchestras or instruments such as flutes, trumpets, violins and pianos were played everywhere from concert halls to restaurants. Today the term â€Å"classical music† has come to define the style of Western music that began in Europe in the Middle Ages. It includes symphonies, chamber music and opera. Classical music is composed of several elements that help define its character. Since music takes place in time, rhythm is the foundation upon which every song is built. Composers determined the feel of music by alternating the pulse between fast, slow, and medium. Italian terms used in musical notation denote more than a dozen different tempos, which included allegro, moderato, and lento. Within the changing meter of rhythm, song notes of various pitches were intertwined. Tone color (timbre) distinguished the sound and characteristics that separated one instrument or voice from another. The classical era between 1750 and 1820 was defined by the great composers who were famous during that period, and the names Mozart and Beethoven stand above all others in the pantheon of Western music.

How to Name a Dinosaur

How to Name a Dinosaur Most working paleontologists dont get the opportunity to name their own dinosaur. In fact, for the most part, paleontology is a somewhat anonymous and tedious occupationthe typical PhD candidate spends most of her days laboriously removing encrusted dirt from newly discovered fossils. But the one chance a field worker really gets to shine is when he or she discoversand gets to namea brand-new dinosaur. (See The 10 Best Dinosaur Names, The 10 Worst Dinosaur Names, and the Greek Roots Used to Name Dinosaurs) There are all sorts of ways to name dinosaurs. Some of the most famous genera are named after prominent anatomical features (e.g., Triceratops, Greek for three-horned face, or Spinosaurus, the spiny lizard), while others are named according to their presumed behavior (one of the most famous examples is Oviraptor, which means egg thief, even though the charges later turned out to be overblown). A bit less imaginatively, many dinosaurs are named after the regions where their fossils were discoveredwitness the Canadian Edmontosaurus and the South American Argentinosaurus. Genus Names, Species Names, and the Rules of Paleontology In scientific publications dinosaurs are usually referred to by their genus and species names. For example, Ceratosaurus comes in four different flavors: C. nasicornus, C. dentisulcatus, C. ingens and C. roechlingi. Most ordinary people can get by with just saying Ceratosaurus, but paleontologists prefer to use both the genus and species names, especially when describing individual fossils. More often than you might think, a species of a particular dinosaur is promoted to its own genusthis has happened numerous times, for instance, with Iguanodon, some former species of which are now referred to as Mantellisaurus, Gideonmantellia and Dollodon. According to the arcane rules of paleontology, a dinosaurs first official name is the one that sticks. For example, the paleontologist who discovered (and named) Apatosaurus later discovered (and named) what he thought was an entirely different dinosaur, Brontosaurus. When it was determined that Brontosaurus was the same dinosaur as Apatosaurus, official rights reverted back to the original name, leaving Brontosaurus as a deprecated genus. (This sort of thing doesnt only happen with dinosaurs; for example, the prehistoric horse formerly known as Eohippus now goes by the less user-friendly Hyracotherium.) Yes, Dinosaurs Can Be Named After People Surprisingly few dinosaurs are named after people, perhaps because paleontology tends to be a group effort and many practitioners dont like to call attention to themselves. Some legendary scientists, though, have been honored in dinosaur form: for example, Othnielia is named after Othniel C. Marsh (the same paleontologist who caused the whole Apatosaurus/Brontosaurus brouhaha), while Drinker wasnt a prehistoric alcoholic, but a dinosaur named after the 19th-century fossil hunter (and Marsh rival) Edward Drinker Cope. Other people-saurs include the amusingly named Piatnitzkysaurus and Becklespinax. Perhaps the most widely recognized people-saur of modern times is Leaellynasaura, which was discovered by a married pair of paleontologists in Australia in 1989. They decided to name this small, gentle ornithopod after their young daughter, the first time a child had ever been honored in dinosaur formand they repeated the trick a few years later with Timimus, an ornithomimid dinosaur named after the husband of this famous duo. (In the past few years, there have been many more dinosaurs named after women, correcting a long-time historical imbalance.) The Silliest, and Most Impressive, Dinosaur Names Every working paleontologist, it seems, harbors the secret desire to come up with a dinosaur name so impressive, so profound, and so just-plain-cool that it results in reams of media coverage. Recent years have witnessed such unforgettable examples as Tyrannotitan, Raptorex and Gigantoraptor, even if the dinosaurs involved were less impressive than you might think (Raptorex, for example, was only about the size of a full-grown human, and Gigantoraptor wasnt even a true raptor, but a plus-sized relative of Oviraptor). Silly dinosaur namesif theyre within the bounds of good taste, of coursealso have their place in the hallowed halls of paleontology. Probably the most famous example is Irritator, which received its name because the paleontologist restoring its fossil was feeling, well, particularly irritated that day. Recently, one paleontologist named a new horned, frilled dinosaur Mojoceratops (after the mojo in the expression Ive got my mojo working), and lets not forget the famous Dracorex hogwartsia, after the Harry Potter series, which was named by pre-teen visitors to the Childrens Museum of Indianapolis!

Literary Criticism on The Star by H.G. Wells Research Paper - 1

Literary Criticism on The Star by H.G. Wells - Research Paper Example   Both of them along with Jules Verne and Hugo Gernsback has been referred to as "The Fathers of Science Fiction". They have always been at the forefront of scientific thinking, they challenged the traditional and conservative views of many people who rejected the advanced and innovative research ideas and stubbornly followed old, outdated conceptions of the universe, the origin of man and the so-called â€Å"higher divine power.† In this work, we will make an attempt to reflect the points of view of both writers to the power of human thought, the role of science in the modern world, as well as the growing conflict between traditional religious beliefs and progressive scientific views. The objects of this essay are the novels â€Å"The Star† by H.G. Wells and â€Å"The Star† by Arthur C. Clarke. â€Å"The Star† by H.G. Wells is an apocalyptic short story written in 1897. It tells us that one day all mankind of the Earth was notified about the penetration of a new star into the solar system. Having disturbed the normal orbit of the planet Neptune, the star quickly approaches the Earth. At first, this fact concerns only astronomers, other people all around the world continue their everyday life not paying much attention to the unknown star. A famous master mathematician publishes his calculations according to which â€Å"the star would either hit Earth or pass by at close proximity, which would lead to apocalyptic ecological consequences† (Wells). The terrible prognoses come true and soon the whole planet is overwhelmed with earthquakes, ice-melting, floods, tsunamis causing â€Å"the devastation across the world. Most of the human population perishes, and its works remain unusable, cities, cathedrals, farms, etc. and when it seems that nothing can save the humanity the killing star suddenly slightly changes its orbit about the Earth to a more distant one† (Wells).

Batteries :: essays research papers

BATTERIES There are many kinds of batteries which consist of different materials in order to produce an electric charge. Here are some of the most common batteries, what they consist of and how they work. Bichromate Cell (see picture # 1) A battery is a device which converts chemical energy into electrical energy. A battery usually consists of two or more cells connected in series or parallel, you can also have a single cell battery. All cells consist of a positive electrode, and a negative electrode. An electrolyte is a liquid substance capable of conducting electricity. In this substance one of the electrodes will react producing electrons, while the other will except electrons. When the electrodes are connected to a device to be powered, called a load, an electrical current flows. Batteries where the chemicals cannot be returned to their original form once the energy has been converted (that is, batteries that have been discharged) are called primary cells or voltaic cells. Batteries in which the chemicals can be returned to its original form by passing an electric current through them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators. Dry Cell Battery(see picture # 2) This is the most common battery that people use today like Energizer or Duracle batteries. The most common form of a primary cell is the Leclanche cell, invented by a French chemist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride made into a paste. The negative electrode is zinc, and is the outside shell of the cell, and the positive electrode is a carbon rod that runs through the center of the cell. This rod is surrounded by a mixture of carbon and manganese dioxide. This battery produces about 1.5 volts. Another widely used primary cell is the zinc-mercuric-oxide cell, more commonly called a mercury battery. It can be made in the shape of a small flat disk and is used in this form in hearing aids, and electric wristwatches. The negative electrode consists of zinc, the positive electrode is of mercuric oxide, and the electrolyte is a solution of potassium hydroxide. The mercury battery produces about 1.34 volts. The fuel cell is another type of primary cell. It is unique in that the chemicals aren't contained within the cell but are supplied from outside of the cell.

Quantitative Analysis for Management

Raptor Fuels produces three grades of gasoline Regular, Premium, and Super. All of these are produced by blending two types of crude oil Crude A and Crude B. The two types of crude contain specific ingredients which help in determining the octane rating of gasoline. The important ingredients and the costs are contained in the following table: [pic] .:. In order to achieve the desired octane ratings, at least 41% of Regular gasoline should be Ingredient 1; at least 44% of Premium gasoline must be Ingredient 1, and at least 48% of Super gasoline must be Ingredient 1.Due to current contract commitments, Raptor Fuels must produce as least 20,000 gallons of Regular, at least 15,000 gallons of Premium, and at least 10,000 gallons of Super. Formulate a linear program that could be used to determine how much of Crude A and Crude B should be used in each of the gasolines to meet the demands at the minimum cost. What is the minimum cost?

The Environmental Impacts Of The Gas Fracking Essay

ESSAY: â€Å"Should Australia continue to allow coal seams to be mined when the environmental impacts are unknown ?† Australia should not approve more coal seam gas mining applications and should urgently investigation the environmental impacts of the Fracking Process. The coal seam gas fracking process has been promoted as the new clean energy yet the process has been shown to cause leaks of carcinogenic chemicals and methane gas in multiple countries including America and Australia. It is also linked to the release of the radioactive Carbon, C226, and potential cancers from silicate. (REF) Australian Federal Mining laws cover extraction for coal and normal gas whereas Coal Seam Gas extraction is covered under it s own laws and regulations that do not requirea Environmental Study (ESI) of the processes water impacts(REF). A Federal body was created in 2004 called the National Water Commission. This Commission was regulated to manage the Great Artesian Basin (GAB) as it covers nearly a quarter of Australia and covers Queensland, NSW and the Northern Territory. This enabled a Federal overview of Australia s resources and decisions. One of it s goals was to promote debate about water issues and respond to the impacts coal seam gas may have on water resources (REF). This Commission was due to release a report in 2015 on the GAB and CSG impacts but the Federal government abolished the Commission in September, 2014. Now the GAB is under a Productivity Commission.
