Comparison and contrast - Essay Example By analyzing these fragments and piecing them together, a modern civilization can extrapolate and theorize about long-term social changes that occurred throughout the rise and fall of empires. In Ancient Greece and Persia, in particular, one can trace the influence of individuality on those two empires’ vision of man’s place on earth. Individuality is a concept rooted in the fabric of Greek society, while it is the value of obedience to god-like authority that one sees most clearly in Persian society. These differing social, moral, and philosophic factors are all perceptible in study of the artworks that have survived from these ancient peoples. Art is particularly useful for understanding the lives and beliefs of ancient peoples because, according to one scholar, art tells a person more about the reality of something than do the bare facts uncovered by empirical investigation (McBrien 132). Because social values strongly influence the individual perception of the world , artworks created by individuals in that context share a great knowledge about the cultural understandings of that social context. Therefore, one of the most important ways of analyzing an ancient culture is to look at its art. One key aspect of any given culture is its view of the individual versus society. Some societies clearly favor an individual’s place in the world, while others clearly support the society over individuals. The bust of Pericles sits in the British Museum and is a slightly idealized version of the Athenian political leader. Although the bust as we see it today is a copy of an earlier work completed by Cresilas, it is faithful to the original and demonstrates the qualities given to the representation of Pericles by the sculptor. Pericles was a famous leader of Athens during the time of the Peloponnesian War and the construction of the Parthenon. Despite the tendency of leaders to be immortalized through history, the history of Pericles is relatively accu rate due to the quality of Athenian historians. In many ways, Pericles represents the golden age of Athens, and his bust reflects that history, without going over to extravagance. In the bust, Pericles peers off into the distance, wearing atop his head a mask of war, and keeping a thick beard. The size of the bust is realistic with respect to its dimensions and how it models an actual human being’s size. These features make the bust look very realistic and human: treating Pericles very much as a man of achievement and virtue, rather than as a god. In contrast, the Persian statue of Darius I, who was treated as a god in his empire, is a depiction of a god and not a mere mortal. It is Egyptian in character, which was a civilization known for treating its rulers as divine beings. A hieroglyphic inscription on the statue states, â€Å"Darius—may he live forever! The statue, formed as a true image of the perfect god, the Lord of the Two Lands† (Mysliwiec and Lorton 1 51). The statue lives up to this commencement: showing the figure as a towering being without attachment to the physical world. While the statue commands an instant attraction to what exactly it means, the purpose of the statue seems immediately clear: to give a sense of reverence and admiration to the leader of the Persian people. Darius clearly used the rhetoric of a godlike figure in order to

Act One of Romeo and Juliet Essay -- English Literature

Act One immediately engages the audience. Do you agree with this statement? How does Shakespeare achieve this? Act One of 'Romeo and Juliet' by William Shakespeare does indeed immediately engage the audience. Shakespeare does this by using several language techniques to create an interesting opening scene. Shakespeare uses humour, action and romance all in Act One and it is this variation that keeps the audience's attention. The play begins with a prologue that is written in the form of a sonnet. The Prologue gives a summary of the play but does not give away too much of the plot, in order to keep the suspense. Shakespeare tells of the great tragedy that will follow. The sonnet form is used because it is more interesting when performed on stage than simple prose. Shakespeare uses clever language in the Prologue to build suspense. For example, on line four he writes, 'From ancient grudge break new mutiny.' 'Ancient grudge' suggests that the disagreement between the Montague and Capulet families has been going on for a very long time and the mutual hatred between them has grown stronger and stronger. The word 'mutiny' is used to mean a sudden outburst of violence, which suggests there will be an exciting, action-packed scene somewhere in the play. Then, on lines six and seven, Shakespeare writes about the 'misadventured piteous overthrows' of the 'pair of star-crossed lovers'. He uses this to suggest there will be several unfortunate tragic accidents involving Romeo and Juliet throughout the play. Furthermore, on line twelve of the sonnet, Shakespeare writes that the play will be 'the two hours' traffic of our stage', meaning that the play will last two hours which will not be long enough to bore the au... ...says. Then finally, they ask each other if they should kiss. They kiss twice but are then interrupted by the Nurse. It is at this point that the couple find out that they come from different sides of the rift between the two households and the audience realise the problem the two lovers face. Act One does immediately engage the audience due to the variety that it contains. Shakespeare uses humour, in particular sexual innuendo, to great effect. The act full of exciting speeches, especially Mercutio's entertaining explanation of 'Queen Mab'. Also, he uses fight scenes for moments of action. There is also lots of emotion displayed by the characters, like Romeo's depression and love-sickness while pining for Rosaline in the opening scene. Shakespeare creates an intriguing opening act that grabs the audience's attention and keeps it well into the next acts.

XYZ Firm has prepared and presented this report in compliance with the Performance Presentation Standards of the Association for Investment Management and Research.AIMR has not been involved with the preparation or review of this report. †¢ Any use of the mark â€Å"AIMR† except as shown above is prohibited. †¢ If results are not in full compliance, performance cannot be presented as: Being in compliance with the AIMR-PPS except for †¦ †¢ Statements referring to the calculation methodology used in a presentation as being in accordance or compliance with AIMR-PPS standards are prohibited. †¢ AIMR members who misuse the term AIMR, AIMR-PPS standards, or the Compliance Statement are subject to disciplinary sanctions under Standard V(B).

The History of the Computer Mouse

It was technology visionary and inventor Douglas Engelbart (January 30, 1925  Ã¢â‚¬â€œ July 2, 2013) who revolutionized the way computers worked, turning it from a piece of specialized machinery that only a trained scientist could use to a user-friendly tool that almost anyone can work with. During his lifetime, he invented or contributed to several interactive and user-friendly devices such as the computer mouse, Windows operating system, computer video  teleconferencing, hypermedia,  groupware,  email, the  Internet  and much more. Making Computing Less Cumbersome Most of all, though, he was known for inventing the computer mouse. Engelbart conceived of the rudimentary mouse while attending a conference on computer graphics, where he started thinking about how to improve interactive computing. In the early days of computing, users typed codes and commands to make things happen on monitors. Engelbart thought an easier way was to link the computer’s cursor to a device with two wheels—one horizontal and one vertical. Moving the device on a horizontal surface would allow the user to position the cursor on the screen. Engelbart’s collaborator on the mouse project  Bill English built a prototype—a hand-held device carved out of wood, with a button on the top. In 1967, Engelbart’s company SRI filed for the  patent on the mouse, although the paperwork identified it a little differently as x,y position indicator for a display system. The patent was awarded in 1970. Computer Mice Hits the Market Before long, computers designed to work with a mouse were released. Among the first was the Xerox Alto, which went on sale in 1973. A team at the Swiss Federal Institute of Technology in Zurich liked the concept as well and built their own computer system with a mouse called the  Lilith computer, sold from 1978 to 1980. Perhaps thinking they were on to something, Xerox soon followed up with  the  Xerox 8010, which featured a mouse, ethernet networking and e-mail among various innovative technologies that have since become standard.   Ã‚   But it wasnt until  1983  that the mouse started to go mainstream. It was that year that Microsoft updated the MS-DOS program Microsoft Word to make it mouse-compatible and developed the first PC-compatible mouse.  Computer manufacturers such as Apple, Atari and Commodore would all follow suit by debuting mouse compatible systems as well.    Tracking Ball and Other Advancements Like other present forms of computer technology, the mouse has evolved significantly. In 1972, English developed the â€Å"track ball mouse† that allowed users to control the cursor by rotating a ball from a fixed position. One interesting enhancement is technology that enables wireless devices, a fact that makes Engelbarts recollection of an early prototype almost quaint. We turned it around so the tail came out the top. We started with it going the other direction, but the cord got tangled when you moved your arm, he said.   For an inventor who grew up on the outskirts of Portland, Oregon and had hoped his achievements would add to the collective intelligence of the world, the mouse has come a long way. It would be wonderful,† he said, â€Å"if I can inspire others, who are struggling to realize their dreams, to say if this country kid could do it, let me keep slogging away.
