Time and Nanotechnology Essay Example for Free

Time and Nanotechnology Essay Do you believe in technology? Or do you think that all inventions of scientists are worthwhile for humanity? Of course, lots of these inventions are helpful and useful. Also, some of them have created new periods in past. They played a big role for coming modernity. However, there are some inventions that seem very effective but they have brought new problems for humanity and environment. Especially, at the beginning of an invention, people don’t realize that it will become big problem. Nowadays, people are taking notice of this kind of things. Nanotechnology is one of these inventions which are needed to be discussed from point to point. Today, there are some people who believe that nanotechnology is dangerous; however some scientists think that nanotechnology has great benefits because it helps people to invent new things for the future. Nanotechnology is a huge area which gives opportunity for other technologies to create better products. With the benefits of nanotechnology, it will be easy to develop new things. First of all, I want to explain a little bit what nanotechnology is. Nanotechnology is taking up the control of matter on a molecular scale. It deals with very little structures which is 100 times smaller. At this scale, properties of products can be changed, giving one the ability to create new things such as create more precise, cleaner, better, stronger and more durable products. For example, today, there are some kind of battery which is produced with nanotechnlogy, much more durable than before. In addition, in the future, it will be easy to invent new products and machines because nanotechnology will play vital role on manufacturing. According to Angelo (2007), â€Å"Nanotechnology promises to fundamentally change the way materials and devices will be produce in the future† (pp. 256). This can be change the future totally. Nanotechnology has contributed so much to advances in many different areas. Lots of technologies are affected from new developments in nanotechnology because these developments open a new period for others. Medicine is the most important area which is affected from nanotechnology. Today, there are some diseases which have not any treatment and cause lots of death. To illustrate, cancer is one of these diseases. But with the usage of nanotechnology in cancer treatments, scientists found a way to treat people. Also, it looks to be more developments on medicine in the future. Another important area is electronics. Like nanotechnology, electronics is very important area for new developments. Nanotechnology has contributed so much to electronics. According to Miller et al. (2004), Nanotechnology has effect on the electronic tools and systems and it is getting possible to develop on computer processing, memory and data storage and demonstration technology (pp. 24). With the usage of nanotechnology, there are lots of materials which are very small, strong and faster than before. The last important area is textile industry. New developments of nanotechnology also play vital role on this industry. Today, new textile products are more durable to heat, UV ray and chemicals because of the changing the structure of products. In addition, it seems to be more advance in the future.

Oil and world Economy Essay -- essays papers

Oil and world Economy Question: Examine the oil industry in relation to the world economy, utilising any economic theory / theories you think appropriate. One of the most important energy resources since human invested the machine is oil and its products. But as all resources scarce, oil is limited even more. Only few countries in the world have oil fields and produce oil for the rest. Therefore, in nowadays where factories, cars and oil-fired central heating increased significantly, oil has become a necessity for the society. People’s demands for oil and its products, fuel, gas and oil for central heating is unlimited, but supplier countries produce a fixed number of barrels of oil everyday so as to maintain a technical shortage and, of course, higher profits. These few countries are the oligopoly of the industry, have a market leader and there are barriers to the entry of new countries (Sloman 1997 : p.124). These countries are dominating the market of oil and created the Organization of Petroleum Exporting Countries (OPEC) in 1960’s. OPEC is an intergovernmental organisation that offers stability and prosperity to the petroleum market. Membership is open to any country which is a great net exporter and which shares the same ideas of this organisation. OPEC has now 11 members and supplies more than the 40% of the worlds oil market. The price of oil over the last year has increased approximately over 100%, reaching the highest levels over the la...

How does the inclusion of the witches in Macbeth heighten the dramatic impact of the play? Essay

Macbeth is a play written by the renowned playwright William Shakespeare in the early 17th century. Originally produced for the King of Denmark, the play explores themes such as ambition and betrayal through the actions of the main protagonist Macbeth. The play’s other significant figures include three witches whose practice of sorcery attracted a lot of controversy towards the play. At the time, their inclusion heightened the dramatic impact on the audience; primarily because of the public’s view of witches. Also referred to as the ‘’weird sisters’’, they form a fundamental element of the play because it is their input that shapes the play into action. During this period of time, the mainstream population of Europe was Christian and superstitious, therefore belief in witchcraft was at its peak and so-called ‘’witches’’ were persecuted. Supposedly, witches (along with Satan) were part of a collective of evil and were blamed for a lot of wrongdoing in society. For instance, political dissidents who opposed the King were thought to be under the influence of black magic. This was because there was commonly held believe that the King had the divine right to rule; thus anyone challenging the King was basically challenging God (which was considered blasphemy and punishable by death). The inclusion of the witches and amount of media coverage they received along with the public’s superstition helped to heighten the dramatic impact of Macbeth on a Shakespearean audience. Today, however, due to the secularisation of society, religious morals are diminishing and witchcraft is seen as nothing more than simple entertainment; this is certainly not how Shakespeare intended it to be. Furthermore, television programmes such as W.I.T.C.H. and books such as the Harry Potter series are depicting witches in a much more positive light. On the other hand, a small number of possible offshoots of witchcraft such as Wicca and Freemasonry are still being practiced despite it being punishable by death in some extremely religious cultures. In this day and age, the general view about witches lessens the dramatic impact significantly because it is seen as a comedy routine therefore Macbeth doesn’t strike fear into the hearts of the audience like its original purpose. In Act 1 Scene 1, as shown in the stage directions; the witches are the first performers when they enter an ‘’open place’’ with ‘’thunder and lightning’’. By being the first performers on stage, they intensify the dramatic impact because the audience focuses their attention towards them. Also, Shakespeare specifically chose the weather in this scene to be threatening, to reflect the negative view of witches at the time and to elevate the dramatic impact by making them see more powerful (witches were associated with the ability to manipulate the weather). The technique of using elements of nature to express mood is known as pathetic fallacy. In this scene, the first impression that the audience are given of the witches is that they are unattractive. For instance, the quotes ‘’your beards’’ and ‘’skinny lips’’ suggests that the witches are ugly and depict them as being unnatural due to having masculine characteristics. Shakespeare has done this to add to the negative interpretation of witches, which in turn heightens the dramatic impact (because the realistic appearance of the witches would frighten the audience). He also uses other characters to highlight the appearance of the witches and therefore raise the dramatic impact on the audience. For instance, Banquo describe the witches as being creatures ‘’ that look not like th’ inhabitants o’ th’ earth’’. He is suggesting that they do not resemble other humans and that they are abnormal; perhaps beings from another world. Shakespeare uses dialogue between the witches to heighten the dramatic impact on the audience. For example, in Act 1 Scene 3, one of the witches says to the others ’‘I’ll drain him dry as hay, sleep shall neither night nor day’’. This line heightens the dramatic impact because it portrays witches as evil because of the reference to torturing someone by depriving him of water. Also the words ‘’hay’’ and ‘’day’’ rhyme, during the Shakespearean era this was related to the spells chanted by witches, therefore the audience would have instantaneously assumed that the lines were malicious; thus increasing the dramatic impact. The lines spoken by the witches also include a rhythm. For example in Act 1 Scene 3, the three witches start their lines with ‘’all hail†¦ all hail†¦ all hail’’, this promotes the idea that the witches have the same thoughts and gives the impression that they are insane because they speak in a different pattern to the other characters. The witches also speak in riddles to scare and confuse the audience, for example, the line ‘’when the battles lost and won’’ may be referring to Macbeth or it could be talking about the struggle for the throne of Scotland. This intensifies the dramatic impact because the audience are left unsure and given the impression that the three witches know something that they don’t. Once again, the witches are depicted as being unnatural because of their ability to prophesise the future. Imagery is used cleverly in many ways by Shakespeare to show the witches in a negative light and add to the dramatic impact. For example, in Act 4 Scene 1, the 1st witch says ‘’round and round the cauldron go, in the poisoned entrails throw’’. This quote emphasizes the popular belief (at the time) that witches chant around their cauldrons which consisted of nauseating ingredients such as rats (creates the image that witches are sick). Also, the witches simultaneously say ‘’double, double toil and trouble, fire burn and cauldron bubble’’, this makes the spell resemble a song more and consequently it increases the dramatic impact. To conclude, the inclusion of the witches in the play undeniably helps to heighten the dramatic impact on a Shakespearean audience. This is mainly because of his successful methods, for example when using pathetic fallacy. Today, however, his masterpiece has not been as popular and effective at creating a negative image of witches because of the enormous change in the public’s view of witches.
