The History of Computing
The Computer - Man’s Greatest Achievment
Computers are indeed approaching the status of the core operator of every electronic device or utility in the world today. Their “logic” and process can produce results millions of times faster than that of the human brain. They are at the helm of everything from an old walk man to the systems that keep the Earth’s continents in constant communications. They’ll likely soon be the basis of communications between other civilizations in outer space. When the computer was first introduced, it was simply a device of convenience for use of the masses or huge corporations and universities. The incredible machines have now grown so much since their introduction, that the World’s economy desperately depends on them to function. But computers have not always been so royal. The first machine to be classified as a computer used no circuitry of any kind, but was consistent entirely of gears and rods that made simple calculations in mathematics. As computers progressed in complexity and became more modern, society utilized them in nearly every way possible. They now are incorporated into every aspect of human life, especially for recreation and general home usage. It remains second in complexity only to that of the human brain. And yet it they still progress towards perfection.
The idea of what is now modern computing originates (more or less) in the late 1700’s with the birth of computing’s conceptual father, Charles Babbage. He was born in London on December 26, 1791, the day after Christmas. He excelled in the area of mathematics (algebra for the most part), acting as his own instructor. He found himself to have been far in intellectual advance of his peers and “mentors”. Upon attending Trinity College, Cambridge in 1811, he still remained at incredible superiority to his tutors. After founding several societies (i.e. Analytical Society, Astronomical Society or Royal Astronomical Society), he became interested in mathematical calculation machines. This ultimately became his life interest. He pursued the invention of a machine that could compile mathematical tables. This gave way to the design of the “Difference Engine”. It performed somewhat complex mathematical tasks using gears and belts, not quite the hardware integrated in todays machines. He eventually conceived the design of an “Analytical Engine” that would be able to make virtually any calculation (at least those considered in the time period) given the proper commands and instructions.
Using the spectrophotometer, the absorption of each sample was measured by scanning the wavelengths. After calibrating the spectrophotometer with the blank test tube, each sample was placed into the spectrophotometer and read at 360nm. Observations were continued for each pigment sample increasing the wavelength by 20nm increments. Once these absorbance values were recorded, absorption spectra for each pigment were graphed.
The American Civil War was a controversial occurrence over slavery lasting four years. Many things led up to this bloody and savage war. The Civil War consisted of 10,500 battles, engagements, and other military actions, and nearly 1,300,000 American casualties (Civil War Facts). Four of the main causes of the Civil War were slavery, abolitionist movement and the Underground Railroad, secession and Fort Sumter, and John Brown’s Harpers Ferry rebellion.
In 500 B.C. the abacus was first used by the Babylonians as an aid to simple arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a "Calculating Clock". This mechanical machine could add and subtract up to 6 digit numbers, and warned of an overflow by ringing a bell. J. H. Mueller comes up with the idea of the "difference engine", in 1786. This calculator could tabulate values of a polynomial. Muellers attempt to raise funds fails and the project was forgotten. Scheutz and his son Edward produced a 3rd order difference engine with a printer in 1843 and their government agreed to fund their next project.
In “God and the Problem of Evil,” B.C. Johnson argues that evil rules out the existence of an all-knowing, all-powerful and all-good God because there are many evil things that are happening in this world. In this paper, I am going to argue that God is only all-good but not all-powerful and all-knowing.
The Civil War, known to be one of the bloodiest wars in the United States, has been a significant factor in the American history. The issues that caused this gory battle between the citizens of the country had been brewing since the nation was formed. Four years of fighting caused about 2% of the populations’ lives. Lives were killed in the field, many dead from illnesses, some wounded, and others taken as prisoners. In retrospection, the Civil War seemed to be inevitable, but there were a few major factors that led to the war. Some of the most important causes Southerners listed for the war were the economic differences between the North and the South, the states' rights, and the issue of whether states would be slave or free.
On the day of November 6, 1860 Abraham Lincoln became our nation’s 16th president. During his time in office one of the nations most talked about wars occurred, The Civil War. The civil war began on April 12, 1861 and lasting till May 9, 1865. The civil war was between the Union States and the states of the Confederacy. The war was caused by many reasons like trade, slavery, and states’ rights. During the civil war Approximately 620,000 soldiers died between the Union States and the states of the Confederacy. The Civil War left many impacts on both the Union States and the states of the Confederacy. Many believe the war help lead to slavery being banned. The civil war also brought great things as well. From bringing military advances and care for veterans to technological and everyday advances. Gettysburg, Chickamauga, Spotsylvania, The
I had recently taken the F-M 100 Hue color test vision test. I have never heard of this test before, so I was unsure what type of test it was. My test score was 60, I don’t believe I have a color vision deficiency but I didn’t find this test easy. In fact it was bothering my eyes at times. My CVD type is undefined, and my CVD severity is none or slight.
Computer engineering started about 5,000 years ago in China when they invented the abacus. The abacus is a manual calculator in which you move beads back and forth on rods to add or subtract. Other inventors of simple computers include Blaise Pascal who came up with the arithmetic machine for his father’s work. Also Charles Babbage produced the Analytical Engine, which combined math calculations from one problem and applied it to solve other complex problems. The Analytical Engine is similar to today’s computers.
Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors. They also have many business files or contracts that need to be strictly protected. Without data encryption, these important information may fall into wrong hands and be misused by others. Besides, data encryption may be used to secure sensitive information that exists on company networks, or create digital signatures, and help to authorize in business. No one should underestimate the importance of encryption. A little mistake in encryption may make sensitive information revealing, or even result in illegal and criminal accuse.
The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.
Since the beginning of time, humans have thought and made many inventions. Repeatedly the newer one is better than the older. Our minds have created many remarkable things, however the best invention we ever created is the computer. computers are constantly growing and becoming better every day. Every day computers are capable of doing new things. Even though computers have helped us a lot in our daily lives, many jobs have been lost because of it, now the computer can do all of the things a man can do in seconds! Everything in the world relies on computers and if a universal threat happens in which all computers just malfunction then we are doomed. Computers need to be programmed to be able to work or else it would just be a useless chunk of metal. And we humans need tools to be able to live; we program the computer and it could do a lot of necessary functions that have to be done. It is like a mutual effect between us and he computer (s01821169 1).
In a world of men, for men, and made by men, there were a lucky few women who could stand up and be noticed. In the early nineteenth century, Lovelace Augusta Byron King, Countess of Lovelace, made her mark among the world of men that has influenced even today’s world. She was the “Enchantress of Numbers” and the “Mother of Computer Programming.” The world of computers began with the futuristic knowledge of one Charles Babbage and one Lady Lovelace, who appeared to know more about Babbage’s Analytical Engine than he himself knew. At the time of Lovelace’s discoveries, women were only just beginning to take part in the scientific world, and her love of mathematics drove her straight into the world of men. Her upbringing, her search for more knowledge, her love of mathematics, and her inherited writing abilities brought to life what we know today as computer programming or computer science.
Technology continued to prosper in the computer world into the nineteenth century. A major figure during this time is Charles Babbage, designed the idea of the Difference Engine in the year 1820. It was a calculating machine designed to tabulate the results of mathematical functions (Evans, 38). Babbage, however, never completed this invention because he came up with a newer creation in which he named the Analytical Engine. This computer was expected to solve “any mathematical problem” (Triumph, 2). It relied on the punch card input. The machine was never actually finished by Babbage, and today Herman Hollerith has been credited with the fabrication of the punch card tabulating machine.
...e industries, textile industries are considered as one of the major sources of wastewater in ASEAN countries. Dyes are also used in industries such as rubber, paper & pulp, dye & dye intermediate industries, pharmaceutical, tannery, food technology, hair coloring, plastic, cosmetic etc. There are more than 10,000 commercially available dyes with over 7x105 tones of dyestuff being produced annually across the world2.. The textile industry consumes more than 107 kg of dye per year of which 90% ending up on fabrics3. Of this total usage 10- 15% of the dye is lost during the dyeing process and released with the effluent. Colour is contributed by phenolic compounds such as tannins, lignins (2-3%) and organic colourants (3-4%) and with a maximum contributions from dye and dye intermediates which could be sulphur/ mordant/ reactive/ cationic/ dispersed/acid/azo vat dye4.
