Engineering Joke Of The Week

A Mathematician was put in a room. The room contains a table and three metal spheres about the size of a softball. He was told to do whatever he wants with the balls and the table in one hour. After an hour, the balls are arranges in a triangle at the center of the table. The same test is given to a Physicist. After an hour, the balls are stacked one on top of the other in the center of the table. Finally, an Engineer was tested. After an hour, one of the balls is broken, one is missing, and he's carrying the third out in his lunchbox.

Macbeth Act 4

The witches are vaguely absurd figures, with their rhymes and beards and capering, but they are also clearly sinister, possessing a great deal of power over events. Are they simply independent agents playing mischievously and cruelly with human events? Or are the “weird sisters” agents of fate, betokening the inevitable? The word weird descends etymologically from the Anglo-Saxon word wyrd, which means “fate” or “doom,” and the three witches bear a striking resemblance to the Fates, female characters in both Norse and Greek mythology. Perhaps their prophecies are constructed to wreak havoc in the minds of the hearers, so that they become self-fulfilling. It is doubtful, for instance, that Macbeth would have killed Duncan if not for his meeting with the witches. On the other hand, the sisters’ prophecies may be accurate readings of the future. After all, when Birnam Wood comes to Dunsinane at the play’s end, the soldiers bearing the branches have not heard of the prophecy. Whatever the nature of the witches’ prophecies, their sheer inscrutability is as important as any reading of their motivations and natures. The witches stand outside the limits of human comprehension. They seem to represent the part of human beings in which ambition and sin originate—an incomprehensible and unconscious part of the human psyche. In this sense, they almost seem to belong to a Christian framework, as supernatural embodiments of the Christian concept of original sin. Indeed, many critics have argued that Macbeth, a remarkably simple story of temptation, fall, and retribution, is the most explicitly Christian of Shakespeare’s great tragedies. If so, however, it is a dark Christianity, one more concerned with the bloody consequences of sin than with grace or divine love. Perhaps it would be better to say that Macbeth is the most orderly and just of the tragedies, insofar as evil deeds lead first to psychological torment and then to destruction. The nihilism of King Lear, in which the very idea of divine justice seems laughable, is absent in Macbeth—divine justice, whether Christian or not, is a palpable force hounding Macbeth toward his inevitable end. The witches’ prophecies allow Macbeth, whose sense of doom is mounting, to tell himself that everything may yet be well. For the audience, which lacks Macbeth’s misguided confidence, the strange apparitions act as symbols that foreshadow the way the prophecies will be fulfilled. The armored head suggests war or rebellion, a telling image when connected to the apparition’s warning about Macduff. The bloody child obliquely refers to Macduff’s birth by cesarean section—he is not “of woman born”—attaching a clear irony to a comment that Macbeth takes at face value. The crowned child is Malcolm. He carries a tree, just as his soldiers will later carry tree branches from Birnam Wood to Dunsinane. Finally, the procession of kings reveals the future line of kings, all descended from Banquo. Some of those kings carry two balls and three scepters, the royal insignia of Great Britain—alluding to the fact that James I, Shakespeare’s patron, claimed descent from the historical Banquo. The mirror carried by the last figure may have been meant to reflect King James, sitting in the audience, to himself.

Macbeth Act 5 Notes

The rapid tempo of the play’s development accelerates into breakneck frenzy in Act 5, as the relatively long scenes of previous acts are replaced by a flurry of short takes, each of which furthers the action toward its violent conclusion on the battlefield outside Dunsinane Castle. We see the army’s and Malcolm’s preparation for battle, the fulfillment of the witches’ prophecies, and the demises of both Lady Macbeth and Macbeth. Lady Macbeth, her icy nerves shattered by the weight of guilt and paranoia, gives way to sleepwalking and a delusional belief that her hands are stained with blood. “Out, damned spot,” she cries in one of the play’s most famous lines, and adds, “[W]ho would have thought the old man to have had so much blood in him?”. Her belief that nothing can wash away the blood is, of course, an ironic and painful reversal of her earlier claim to Macbeth that “[a] little water clears us of this deed”. Macbeth, too, is unable to sleep. His and Lady Macbeth’s sleeplessness was foreshadowed by Macbeth’s hallucination at the moment of the murder, when he believed that a voice cried out “Macbeth does murder sleep”. Like Duncan’s death and Macbeth’s ascension to the kingship, Lady Macbeth’s suicide does not take place onstage; it is merely reported. Macbeth seems numb in response to the news of his wife’s death, which seems surprising, especially given the great love he appears to have borne for his wife. Yet, his indifferent response reflects the despair that has seized him as he realizes that what has come to seem the game of life is almost up. Indeed, Macbeth’s speech following his wife’s death is one of the most famous expressions of despair in all of literature.

Macbeth Act 3 Notes

After his first confrontation with the witches, Macbeth worried that he would have to commit a murder to gain the Scottish crown. He seems to have gotten used to the idea, as by this point the body count has risen to alarming levels. Now that the first part of the witches’ prophecy has come true, Macbeth feels that he must kill his friend Banquo and the young Fleance in order to prevent the second part from becoming realized. But, as Fleance’s survival suggests, there can be no escape from the witches’ prophecies. Macbeth and his wife seem to have traded roles. As he talks to the murderers, Macbeth adopts the same rhetoric that Lady Macbeth used to convince him to murder in Act 1, scene 7. He questions their manhood in order to make them angry, and their desire to murder Banquo and Fleance grows out of their desire to prove themselves to be men. In the scene with Lady Macbeth that follows, Macbeth again echoes her previous comments. She told him earlier that he must “look like the innocent flower, / But be the serpent under’t” . Now he is the one reminding her to mask her unease, as he says that they must “make [their] faces visors to [their] hearts, / Disguising what they are” . Yet, despite his displays of fearlessness, Macbeth is undeniably beset with guilt and doubt, which he expresses in his reference to the “scorpions” in his mind and in his declaration that in killing Banquo they “have scorched the snake, not killed it” . Throughout Macbeth, as in many of Shakespeare’s tragedies, the supernatural and the unnatural appear in grotesque form as harbingers of wickedness, moral corruption, and downfall. Here, the appearance of Banquo’s silent ghost, the reappearance of the witches, and the introduction of the goddess Hecate all symbolize the corruption of Scotland’s political and moral health. In place of the dramatization of Macbeth’s acts of despotism, Shakespeare uses the scenes involving supernatural elements to increase the audience’s sense of foreboding and ill omen. When Macbeth’s political transgressions are revealed, Scotland’s dire situation immediately registers, because the transgressions of state have been predicted by the disturbances in nature. In Macbeth’s moral landscape, loyalty, honor, and virtue serve either as weak or nonexistent constraints against ambition and the lust for power. In the physical landscape that surrounds him, the normal rules of nature serve as weak constraints against the grotesqueries of the witches and the horrific ghost of Banquo. The banquet is simultaneously the high point of Macbeth’s reign and the beginning of his downfall. Macbeth’s bizarre behavior puzzles and disturbs his subjects, confirming their impression that he is mentally troubled. Despite the tentativeness and guilt she displayed in the previous scene, Lady Macbeth here appears surefooted and stronger than her husband, but even her attempts to explain away her husband’s “hallucination” are ineffective when paired with the evidence of his behavior. The contrast between this scene and the one in which Duncan’s body was discovered is striking—whereas Macbeth was once cold-blooded and surefooted, he now allows his anxieties and visions to get the best of him.

Macbeth Act 2 Notes

Banquo’s knowledge of the witches’ prophecy makes him both a potential ally and a potential threat to Macbeth’s plotting. For now, Macbeth seems distrustful of Banquo and pretends to have hardly thought of the witches, but Macbeth’s desire to discuss the prophecies at some future time suggests that he may have some sort of conspiratorial plans in mind. The appearance of Fleance, Banquo’s son, serves as a reminder of the witches’ prediction that Banquo’s children will sit on the throne of Scotland. We realize that if Macbeth succeeds in the murder of Duncan, he will be driven to still more violence before his crown is secure, and Fleance will be in immediate and mortal danger. Act 2 is singularly concerned with the murder of Duncan. But Shakespeare here relies on a technique that he uses throughout Macbeth to help sustain the play’s incredibly rapid tempo of development: elision. We see the scenes leading up to the murder and the scenes immediately following it, but the deed itself does not appear onstage. Duncan’s bedchamber becomes a sort of hidden sanctum into which the characters disappear and from which they emerge powerfully changed. This technique of not allowing us to see the actual murder, which persists throughout Macbeth, may have been borrowed from the classical Greek tragedies of Aeschylus and Sophocles. In these plays, violent acts abound but are kept offstage, made to seem more terrible by the power of suggestion. The effect on Lady Macbeth of her trip into Duncan’s bedroom is particularly striking. She claims that she would have killed Duncan herself except that he resembled her father sleeping. This is the first time Lady Macbeth shows herself to be at all vulnerable. Her comparison of Duncan to her father suggests that despite her desire for power and her harsh chastisement of Macbeth, she sees her king as an authority figure to whom she must be loyal. After the bloody imagery and dark tone of the previous two scenes, the porter’s comedy comes as a jarring change of tone. His good-natured joking with Macduff breaks up the mounting tension of the play and also comments obliquely on its themes. Unlike all the characters of noble birth, who speak in iambic verse, the porter speaks in prose. His relaxed language seems to signal that his words and his role are less important than those of the other characters, but in his merry banter the porter hits on many truths. His description of the confusion and lust provoked by alcohol caricatures Macbeth’s moral confusion and lust for power. Moreover, his remarks about the ineffective lechery inspired by drink eerily echo Lady Macbeth’s sexual taunting of Macbeth about his ability to carry out his resolutions. The porter’s joke that the door of Inverness is like hell’s gate is ironic, given the cruel and bloody events that are taking place within the castle. When he cries, “Who’s there, i’ th’ name of Beelzebub [the devil]?” the analogy between hell and Inverness becomes even stronger (2.3.3). Instead of receiving a welcome and a blessing when they step into Macbeth’s castle, guests are warned that they are putting themselves in the hands of the devil. Now that Lady Macbeth’s machinations have wrought their result, Lady Macbeth begins to recede from center stage and Macbeth takes her place as the most compelling character in the play. The clipped, halting sentences with which Macbeth speaks to Macduff and Lennox indicate his troubled mind and trepidation about the impending discovery of Duncan’s body. For example, while Lennox offers a lengthy speech about the wild weather of the previous night, Macbeth’s only response is a terse “ ’Twas a rough night”. And when Lennox asks Macbeth, “Goes the King hence today?” Macbeth almost gives away his knowledge that Duncan is dead. “He does,” answers Macbeth, before he realizes that his answer is incriminating and changes it to: “[H]e did appoint so”.

Macbeth Act 1

These scenes establish the play’s dramatic premise—the witches’ awakening of Macbeth’s ambition—and present the main characters and their relationships. At the same time, the first three scenes establish a dark mood that permeates the entire play. The stage directions indicate that the play begins with a storm, and malignant supernatural forces immediately appear in the form of the three witches. From there, the action quickly shifts to a battlefield that is dominated by a sense of the grisliness and cruelty of war. In his description of Macbeth and Banquo’s heroics, the captain dwells specifically on images of carnage: “he unseamed him from the nave to th’ chops,” he says, describing Macbeth’s slaying of Macdonwald. The bloody murders that fill the play are foreshadowed by the bloody victory that the Scots win over their enemies. Our initial impression of Macbeth, based on the captain’s report of his valor and prowess in battle, is immediately complicated by Macbeth’s obvious fixation upon the witches’ prophecy. Macbeth is a noble and courageous warrior but his reaction to the witches’ pronouncements emphasizes his great desire for power and prestige. Macbeth immediately realizes that the fulfillment of the prophecy may require conspiracy and murder on his part. He clearly allows himself to consider taking such actions, although he is by no means resolved to do so. His reaction to the prophecy displays a fundamental confusion and inactivity: instead of resolving to act on the witches’ claims, or simply dismissing them, Macbeth talks himself into a kind of thoughtful stupor as he tries to work out the situation for himself. In the following scene, Lady Macbeth will emerge and drive the hesitant Macbeth to act; she is the will propelling his achievements. Once Lady Macbeth hears of the witches’ prophecy, Duncan’s life is doomed. These scenes are dominated by Lady Macbeth, who is probably the most memorable character in the play. Her violent, blistering soliloquies in Act 1, scenes 5 and 7, testify to her strength of will, which completely eclipses that of her husband. She is well aware of the discrepancy between their respective resolves and understands that she will have to manipulate her husband into acting on the witches’ prophecy. Her soliloquy in Act 1, scene 5, begins the play’s exploration of gender roles, particularly of the value and nature of masculinity. In the soliloquy, she spurns her feminine characteristics, crying out “unsex me here” and wishing that the milk in her breasts would be exchanged for “gall” so that she could murder Duncan herself. These remarks manifest Lady Macbeth’s belief that manhood is defined by murder. When, in Act 1, scene 7, her husband is hesitant to murder Duncan, she goads him by questioning his manhood and by implicitly comparing his willingness to carry through on his intention of killing Duncan with his ability to carry out a sexual act. Throughout the play, whenever Macbeth shows signs of faltering, Lady Macbeth implies that he is less than a man. Macbeth exclaims that Lady Macbeth should “[b]ring forth men-children only” because she is so bold and courageous. Since Macbeth succumbs to Lady Macbeth’s wishes immediately following this remark, it seems that he is complimenting her and affirming her belief that courage and brilliance are masculine traits. But the comment also suggests that Macbeth is thinking about his legacy. He sees Lady Macbeth’s boldness and masculinity as heroic and warriorlike, while Lady Macbeth invokes her supposed masculine “virtues” for dark, cruel purposes. Unlike Macbeth, she seems solely concerned with immediate power.

Engineering Joke Of The Week

An engineering student was walking across campus when another engineer rides up on a shiny new motorcycle. "Where did you get such a rockin' bike?" asked the first. The second engineer replied, "Well, I was walking along yesterday minding my own business when a beautiful woman rode up on this bike. She threw the bike to the ground, took off all her clothes and said "Take what you want." The second engineer nodded approvingly "Good choice, the clothes probably wouldn't have fit."
