...Optics Mirrors and Lenses Reflection We describe the path of light as straight-line rays Reflection off a flat surface follows a simple rule: angle in (incidence) equals angle out (reflection) angles measured from surface “normal” (perpendicular) Reflection Vocabulary Real Image – Image is made from “real” light rays that converge at a real focal point so the image is REAL Can be projected onto a screen because light actually passes through the point where the image appears Always inverted Reflection Vocabulary Virtual Image– “Not Real” because it cannot be projected Image only seems to be there! Virtual Images in Plane Mirrors Hall Mirror Useful to think in terms of images LEFT- RIGHT REVERSAL Curved mirrors What if the mirror isn’t flat? light still follows the same rules, with local surface normal Parabolic mirrors have exact focus used in telescopes, backyard satellite dishes, etc. also forms virtual image Concave Mirrors Curves inward May be real or virtual image For a real object between f and the mirror, a virtual image is formed behind the mirror. The image is upright and larger than the object.

Ans- The character of Bishop represent the heads of church, in substance with a penchant for dressing up in sumptuous costumes to play out their preferred roles. Bishop have required the real powers that these figure represent but only because the former Bishop have been routed by revolution. Genet comments on the institution of the church through the role-acting of the Bishop. The visitors in the brothel’s studio dose not remain an individual but represent the Bishop who has religious power which is perhaps the oldest established power. The visitor is an ordinary man but wants to live his fantasy of power and sex. The visitors enacting the Bishop does not want to be real Bishop.

...writing on holy people. In catholic tradition, it is the writing of a saint's live, a study of a saint life. It does not necessarily attempt to give full details, historical account of the life of an individual saint. Rather, it is written so that their life can be an inspiration to people. It is written so that their life can have a salvific effect on people. It is also written so that people can also reflect on the outcome of their life, helps strengthen people's faith. Finally, Hagiography helps us to see the saints as a mirror for us to imitate. Legend is from the Latin word legenda which means something to be read about the life a saint. The Catholic church sees that this person has done something worth worthy therefore it has to be written for everybody because the life of the person worth to imitate. It is written down so that those who have not heard about the person's life can know something about him/her too. So that everyone will see them as a mirror to imitate, role model and as a inspirator. It is written also in order to be read during the feast day or name day of the saint. These are read during holy hour, at meal time The purpose of reading the life of a saint is for edification. Testament is something someone writes as a wish to follow before he/she dies. It reflects the experience, their thoughts, intentions of the person and what he/she wants the people to follow and do. Francis of Assisi wrote his testament two years before he died. He wrote it in agony while...

...INTRODUCTION A mirror is an object that reflects light or sound in a way that preserves much of its original quality prior to its contact with the mirror. Some mirrors also filter out some wavelengths, while preserving other wavelengths in the reflection. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image (“Mungan,” 1999). Geometrical optics, or ray optics, describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction, or "instrument", which can be used to approximately model how light will propagate. Geometrical optics provides rules, which may depend on the color (wavelength) of the ray, for propagating these rays through an optical system. This is a significant simplification of optics that fails to account for optical effects such as diffraction and interference. It is an excellent approximation, however, when the wavelength is very small compared with the size of structures with which the light interacts (“Hecht,” 1987). Glossy surfaces such as mirrors reflect light in a simple, predictable way. This allows for production of reflected images that can be associated with an actual (real) or extrapolated (virtual)...

...xcept Louisiana have passed the Uniform Commercial Code’s (UCC) Article 2 which sets the rules and guidelines for contracts dealing with goods. Essentially, in order for a contract to be valid, there must be an offer and acceptance of the offer, all parties must be legally capable of entering into a contract, there must be evident consideration, and most states have a Statue of Frauds. To expand on offer and acceptance: A proposed contract must be offered by one party, known as the “offeror,” and accepted by the other party, known as the “offeree.” Offers must be certain and even if an offer has been made, the contract has not been formed until the offeree accepts the offer. Terms of acceptance and rejection are different for every contract. In certain cases, as stipulated by the idea of common law exactness, such as in realty, services, or insurance, the acceptance must be the mirror image of the offer and if not, the offer is considered to be rejected and a counteroffer occurs. However, when goods not in those industries are not involved, the mirror image rule does not have to be followed. Both of these parties must be capable of making contracts in order for a contract to be considered valid and enforceable. There are groups of people that are exceptions and upon entering into a contract, may not be held liable. This includes minors as well as intoxicated or otherwise mentally-handicapped individuals. Another aspect that must be part of a contract...

...Elements of a Contract BUS670 Legal Environment October 27, 2014 When talking in terms of a contract there are five elements that must exist in order for a contract to be enforceable. “The phrase enforceable by a court is significant because it means that a court can assess monetary damages against a party who does not comply with the terms of the agreement.” (Seaquist, 2012) The criteria that must be present in order to be enforceable are; offer, acceptance, consideration, capacity, and legality. The first element that must be in agreement to make a contract enforceable is offer. In the contracts there are two people who are mentioned which are the offeror and offeree. The offeror is the person who is making the offer and the offeree is the party who is accepting the offer. Offers in contracts have different language from a preliminary negotiations. The thing that set them apart is that the language is definite and certain in nature. A few years ago I had to write a contract for a young Airman who was interested in buying my car and could not afford to pay for it all at one time. I started off the contract saying, “I agree to sell you my car” this showed her that I was offering her something that was going to be enforceable. Prior to starting work at the Fabulous Hotel an offer was made to me by the hotel. The offer stated the pay, hours and location. The offer is where you do your negotiating for what you want to get out of the contract. “The...

...and how much they relied on nature. They adored nature to such a degree, to the point that they designed divine beings, who encapsulated the nature itself, to secure it. How about we consider, for instance, the Roman Flora, image for nature, blooms and fruitfulness, the Greek Ceres, likewise called Demeter or the Goddess of Earth who were human reciprocals of the normal components. Metamorphoses of Ovid’s expanded upon the topic to speak of those changed into new entities and, very often, those entities came from the natural world. Emblematic is the anecdote of Daphne e Apollo: fated by Cupid’s love-arrow, sees Daphne, who flees him because she’s been fated by Cupid’s love-repelling arrow and denies his love. Apollo pleads and persists, and Daphne cries out to her father for help. He responds by transforming her into a laurel tree....

...Wilson her credit card statement, which informed her that it was modifying the terms of the original agreement. This revised agreement was enclosed with the credit card statement. After the July 2001 statement was made to her, Wilson continued using her credit card and made monthly payments on her account balance. Wilson made her last payment to Citibank in March 2002 and failed to make payments thereafter. Citibank then failed suit against her to collect her overdue balance, which was $12,272.84. In this action, Citibank attempted to enforce the revised agreement rather than the original agreement. Wilson argued that she never accepted the revised agreement. Is this a good argument? Issue: Did Wilson agree on the revised agreement? Rule: The elements for acceptance were (1) the offeree intended to enter the contract, (2) the offeree accepted on the terms proposed by the offeror, and (3) the offeree communicated his acceptance to the offeror. Application: Citibank first must prove that Wilson’s intention to enter the contract. If the offeree objectively indicates a present intent to contract on the terms of the offer for a contract to result, this element is satisfied. Here, since Wilson applied for Citibank credit card, which could be interpreted as the offeree’s present intent from reasonable person’s point of view. Wilson communicated her acceptance the Citibank by signing. Citibank also must prove that the offeree accepted on the terms proposed by the offeror...

...Question: To what extent is literature like a mirror? Inquiry paper In Ovid’s Metamorphosis, Narcissus is a handsome young man who saw the reflection of his face in the waters of the Styx River. He became so captivated by his own reflection, that he sat looking at himself until he died and a small flower grew in his place. After the manufacturing and widespread existence of mirror, human have became obsessed with the reflections of themselves. Literature provided us with a unique type of mirrors. It helps us to discover the perfection of ourselves but at the same time, grab our eyes on the defectiveness as well. Just like Narcissus, we never stop seeking for self-identification and self-conscious through the way we look at our own images. An examination of the books I read, I found literature to be like a mirror to a great extent in many ways. The Secret daughter by Shilpi Somaya Gowda, is a book that compares the treatments of females in two different families - one in India and one in America. The book begins with the unforgettable birth of a baby girl named Usha in a remote Indian village on the eve of monsoon. In a culture where females’ infanticide is rampant, Kavita, the baby’s mother sent her daughter to an orphanage in order to save her life. Dr. Somer, an American woman who adopts Usha (they call her Asha) after the discovering that she can never have children of her own. The two women mirror each other in the sense that they both make difficult decisions to save and...

...Elements of a Contract BUS 670 August 25, 2015 Elements of a Contract Introduction A contract is a legal agreement between two entities that creates obligations by both parties that are enforceable by law. As Verkerke (2015) notes, individuals are often ill-informed of the legality of most common dealings in their lives. With a common ignorance of legal matters, it is essential that contracts contain the required elements to be legally binding and protect both parties involved. Additionally, it is pertinent to understand the difference between contracts governed by common law and those governed by the Uniformed Commercial Code (UCC). Finally, prior to signing a non-compete agreement or asking someone to, it is important to understand the circumstances that make it enforceable as well as the diversity of enforcement standards as they vary from state to state. Five Elements Required for Enforcement Every contract contains promises that are enforceable, however only certain conditions are enforceable by a court if they meet the following five elements: an offer, an acceptance, consideration, capacity, and legality (Seaquist, 2012). The first element, the offer, occurs between two parties, the offeror (the one who makes the offer) and the offeree (the one who has the option to accept the offer) which grants the offeree the power of acceptance (Seaquist, 2012). Although some preliminary negotiations may take place before the final acceptance of the offer, they are...

...The Ambiguity of Weeping. Baroque and Mannerist Discourses in Haynes’ Far from Heaven and Sirk’s All That Heaven Allows. Jack Post Abstract Although Douglas Sirk’ All That Heaven Allows (1954) and Todd Haynes’ Far from Heaven (2002) are both characterized as melodramas, they address their spectators differently. The divergent (emotional) reactions towards both films are the effect of different rhetorical strategies: the first can be seen a typical example of baroque discourse and the latter as a specimen of mannerist discourse. The reference to the terms melodrama, mannerism and baroque does not imply that these films are just formal repetitions of historical periods or that they thematically and structurally refer to historical styles, but that they are characterized by opposing discursive strategies which came to the foreground in a specific historical time and constellation. Because these discursive strategies return in other historical periods and socialpolitical circumstances in different guises and with different aims, they can be compared to what Aby Warburg calls Pathosformeln (pathos formula). The expressive forms, gestures and discursive modes of melodrama, baroque and mannerism can thus be understood as transhistorical (gestural) languages of pathos that recur in history. Résumé Bien que All that heaven allows (1954) par Douglas Sirk et Far from heaven (2002) par Todd Haynes se caractérisent nettement comme un mélodrame, les deux films adressent...
