The History And How Of Computers - 915 Words

The History and How of Computers Everything you do on a computer or phone is meticulously programmed. Surfing the web requires HTML, CSS, JavaScript, JQuery, and PHP. Lines upon lines written such as â€Å"$temp = password_hash($object-password, PASSWORD_BCRYPT);†. The binary zeros and ones of machine code turn into video games, websites, and programs such as what you are using right now to read this. The age of information was brought forth by the ability to access all known information and share new knowledge. The unsung founders of the age of information are programmers that created the links between peers that we now call the World Wide Web. In the past 200 years, a computer has gone from reading punch cards to running simulations on how the universe was created. In the beginning, there was Jacquard. Joseph-Marie Jacquard was an inventor in France between the 18th and 19th centuries. His most famous work was the Jacquard loom, which read a punch card in order to weave a ch osen design into cloth. In 1822, Charles Babbage had the idea of a device powered by steam to calculate tables of numbers, although the idea was to be funded by the English government, it never came to be (The Engines). Decades later, in 1890, Herman Hollerith revamped the punch card system in order to calculate the census. Hollerith’s company became what we know as IBM who later paved the way for data storage by floppy discs and hard drives (â€Å"IBM is Founded†).

The Glass Castle free essay sample

Jeannette Walls’ memoir, The Glass Castle, gives a vivid description of what life is like growing up in a poor family where parental negligence and limited supervision is common. Walls grows up with a high tolerance for hard times and bravery that is unmatched. Her self-sufficiency and education helped Walls escape her difficult childhood and poor family life growing up. Walls’ memoir clearly refutes the statement made in The Great Gatsby by Daisy Buchanan that the best thing a girl can be in this world, [is] a beautiful, little fool† (Fitzgerald 17). In Walls’ eyes, the best thing a girl can be is strong, motivated, and, most importantly, educated. Throughout The Glass Castle, Walls uses anecdotes, figurative language, and a repetition of words that proves her stance is one that plainly contradicts Daisy’s statement about what furthers the life of women. First, Jeannette Walls uses an anecdote in The Glass Castle that displays how education is what allowed her to further herself in society. We will write a custom essay sample on The Glass Castle or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the beginning of the novel, Walls tells stories about how her parents, especially her dad, had taught her how to read before grade school and made everything more difficult so that she would be smarter than the rest of the children. She mentioned one time when her dad made her use binary numbers to do her math homework and how her teacher did not approve. When Walls enters high school, she uses an anecdote to prove how it was her education that allowed her to go from proofreader of the school paper to editor-in-chief quicker than anyone else had before. Because Walls had been pushed by her parents to be smarter than the other kids, she was able to join the school paper in the seventh grade. To show just how important that was in furthering herself, Walls writes, â€Å"Miss Bivens told me that as far as she could remember, I was the only seventh-grader who’d ever worked for the Wave,† (Walls 203). Walls continues the story by laying out the years before the eleventh grade when she writes, â€Å"That fall, when I was going into the tenth grade, Miss Bivens made me news editor of The Maroon Wave. After working as a proofreader in the seventh grade, I’d started laying out pages in the eighth grade, and in the ninth grade I began reporting and writing articles and taking photographs† (Walls 231). The story ends with Walls writing, â€Å"When I was a junior, Miss Bivens made me editor in chief, though the job was supposed to go to a senior† (Walls 232). This anecdote told by Walls plainly refutes Daisy’s statement about how the only way for a woman to further herself is by her looks because Walls furthered herself through education. Walls is able to move up the chain of command in the school newspaper by using no more than her talent for writing. Next, Jeannette Walls stance can be proven through her figurative language because her life is an example that contradicts Daisy’s statement. Walls never saw herself as being beautiful and she had what her mom called ‘distinctive looks’. To explain this to the reader, Walls writes, My elbows were like flying wedges and my knees like tea saucers† (Walls 200). This simile portrays her as not being that attractive, but Walls is still able to succeed in life and further herself as a woman. When Miss Katona uses prom as a reason for Jeannette to stay in Welch, she writes, â€Å"As for the senior prom, I had about as much chance of getting a date as Dad did of ending corruptions in the unions (Walls 236). This analogy refutes Daisy’s statement again because it shows that Walls is not very attractive, but she is still able to further herself later in life. Her dad explained that â€Å"she already fought the fire once and won † (Walls 15). This personification of fire brings light upon the fact that Jeannette is brave. Her bravery is another thing that allows her to further herself in life because she is not scared to move away from her parents at only seventeen. Since Walls is able to grow up and acquire a college degree and a steady job, her life contradicts Daisy because Jeannette is neither beautiful nor a fool. Lastly, Walls repeats the word ‘mountain goat’ to emphasize that a woman must have a strong will in order to further herself in life. The word is a nickname given to Jeannette by her father, Rex Walls. The nickname refers to her ability to stay focused in the face of danger because, like a mountain goat, she is able to climb mountains without losing her footing, which takes a strong will in order to accomplish. Jeannette writes, â€Å"I never fell down when we were climbing mountains sure footed as a mountain goat, hed always say† (Walls 36). The word is also used to show bravery in Jeannette and how that trait allows her to get away from Welch. Rex explains to Jeannette that â€Å"All you have to do, Mountain Goat, is show old Demon that you’re not afraid† (Walls 36). This is one of the first uses of the word ‘mountain goat’ in The Glass Castle and it puts emphasis on the idea that Jeannette is not afraid of anything. When Jeannette finally finishes college and asks Rex to come to her graduation, he replies, â€Å"I don’t have to see my Mountain Goat grabbing a sheepskin to know she’d got her college degree† (Walls 267). This reveals that after all the hard work and the bravery Jeannette showed, she was able to further herself farther than anyone else in her family ever could. This nickname that Rex gives Jeannette foreshadows her bravery when she has to live apart from her parents and siblings when she is only seventeen. Jeannette Walls usage of anecdotes, figurative language, and a repetition of the word ‘mountain goat’ can be used to prove that her stance on what the best thing a woman can be clearly refutes that of Daisy’s stance from The Great Gatsby. Walls anecdote about becoming editor-in-chief shows that education can also further a woman in life. The idea that Walls is unattractive also refutes Daisy’s statement because Walls was able to further herself without being considered beautiful. Lastly, she uses a repetition of the word ‘mountain goat’ to emphasize that she believes that one of the best things a woman can be is strong-willed and brave. Although Jeannette Walls had a strong argument for what the best thing a woman could be, the best thing for her might not always be the best thing for everyone.

Wastewater Treatment Essays - Sewerage, Environmental Engineering

Wastewater Treatment The reason for me doing this report is because I could not attend class enough to grasp the concept of Wastewater Treatment. This report is an overview of each stage of the treatment of sewage. I have included a diagram of a typical sewage plant. A) Primary Treatment The wastewater that enters a treatment plant contains debris that might clog or damage the pumps and machinery. The material is removed by screens, and is burned or buried. The wastewater then passes through a comminutor (grinder), where all the organic material such as leaves are mushed smaller so that they can be removed later. 1) Grit Chamber Back in the day, long narrow channel-shaped settling tanks, known as grit chambers, were used to remove all the inorganic substances like sand, silt, gravel, and cinders. These chambers were made to allow inorganic particles 0.008 in. or bigger to settle at the bottom while the smaller particles and most of the organic material that remain in suspension pass through. Today, spiral-flow aerated grit chambers with hopper bottoms, or clarifiers with automatic scrapper arms are used. The grit is removed and disposed of as sanitary landfill. Grit build up can reach from 3 to 8 cubic feet per1 million gallons of wastewater. 2) Sedimentation With the grit removed, the wastewater goes into a sedimentation tank, where the organic materials removed. The method of sedimentation can remove about 20 to 40 percent of the biochemical oxygen demand and 40 to 60 percent of the suspended solids. The big boys in the industry use a chemical process known as coagulation and flocculation in the sedimentation tank. I really don't know much about this subject so I'm going to move on. 3) Flotation The alternative to sedimentation is a treatment called flotation, in which air is forced into the wastewater under pressures of 25 to 50 lbs per sq. in. The wastewater, is compressed with air, is then released into an open tank ; there the rising air bubbles cause the suspended solids to rise to the surface, where the are wisked away. Flotation can remove more than 75 percent of the suspended solids. 4) Digestion Digestion is a microbiological process that changes the chemically complex sludge to methane, carbon dioxide, and a harmless fertilizer. The reactions occur in a closed tank or digestor that is oxygen deficient. The transformation happens after a series of reactions. First the solid matter is made soluble by enzymes, then the substance is fermented by a group of acid-producing bacteria, reducing it to simple organic acids such as acetic acid. The organic acids are then resolved to methane and carbon dioxide by bacteria. The sludge that is to thick is heated and added to the digester as many times as possible, where it sits for 10 to 30 days and is decomposed. Digestion reduces organic matter by 45 to 60 percent. 5) Drying The digested sludge is place on sand beds for air drying. Air drying needs dry, warm weather for it to work. Some plants have shelters over the sand beds. Dried sludge in most cases is used as a fertilizer because of the 2 percent nitrogen and 1 percent phosphorus content. B) Secondary Treatment After removing 40 to 60 percent of the suspended solids and 20 to 40 percent of the BOD5 in the primary stage by physical resources, the secondary treatment biologically reduces the organic material that stayed in the liquid stream. Secondary treatment contains keeping and speeding up nature's process of waste disposal. Aerobic bacteria in the oxygen change the organic matter to stable forms such as CO2 , water, nitrates, and phosphates. The new organic material that is made is an indirect result of biological treatment processes, and is removed before the wastewater is dumped into the streams. 1) Trickling Filter In this process, a waste stream is sent over a bed or column of some type of porous medium. A sticky film of microorganisms coats the medium and acts as the removal agent. The organic matter in the waste stream is absorbed by the film and changed to carbon dioxide and water. If the trickling filter step comes before the sedimentation stage it can remove about 85 percent of the BOD entering the plant. 2) Activated Sludge This stage is an aerobic process that adds sticky sludge particles that have millions of of actively growing bacteria stuck together by a gelatinous slime. Organic matter is assimilated by the floc and changed to aerobic output. The reduction of BOD varies between 60 to
