Antiaging technologies - Essay Example The administrator believes that almost every normal person wishes to live long and remain youthful to a given level. In respect of this, the administrator believes that increasing people’s life expectancies is one of the major duties of a health facility. In his view, those who are opposed to anti-aging technologies are â€Å"new puritans† in that they are ready to oppose medical advancements on every single ground. The administrator claims that humans have doubled their lifespan from time immemorial. In respect of the same, using anti-aging technologies should be embraced worldwide without having to find new sources of stem cells. The hospital administrator interviewed is for the idea of using anti-aging technologies. According to him, human life ought to be prolonged to the greatest extent possible in spite of the associated dilemmas. He believes that humans have always sought to increase their life expectancy from time immemorial and therefore anti-aging technologies should be equally

Un Action Against Terrorism Essay The issue of coming up with ways to combat terrorism has been prioritized by the entire community internationally and it is also a major task in the United Nations. Various UN bodies have come up with different initiatives to try and combat terrorism and bring to justice those involved with the act. The most controversial issue within the UN in its battle against terrorism is the counter terrorism measures that are stipulated in the resolutions of the UN Security Council. One of the most serious threats towards human rights in the world is terrorism as it takes lives of thousands of innocent people every year and also breaks democratic orders. It is quite important for Countries to react to any threat of terrorism but at the same time there have been concerns that some forceful measures against terrorism may also greatly violate the human rights. The UN requires balancing the two competing interests in the fight against terrorism which are individual rights on one hand and protection of civilian and national security on the other hand. In some exceptional circumstances to curb threats and activities of terrorism there may be some justification to the abuse of human rights but only when it is an emergency case. It is very important for any country to ensure that any decisions that are made in order to preserve national security are according to the law, compensation is done to individuals whose rights were violated and those decisions should be subjected to review in the near future to avoid violation of human rights. The UN did not make any attempt to resume or revive the efforts that the League of Nations had made to control international terrorism after these rules were greatly interrupted by the Second World War. These efforts had finished the integration of the 1973 complementary conventions to deal with the punishment and prevention of terrorism and also the establishment of an International Criminal Court. This has resulted in a problem of international terrorism as it has been observed in a number of actions that have been carried out by the UN involving progressive development and codification of the international law since the early 1950s. Before the year 1972 the issue of terrorism was not a major topic of discussion in the general assembly of the UN. In 1972 there was a kidnapping of Israeli athletes at Munich during the Olympic Games, as this was seen as an act of terrorism, the then Secretary-General of the UN introduced an item on measures to curb terrorism and any kind of violence that would take innocent lives or endanger any human fundamental freedom to be discussed in the twenty-seventh session of the United Nations National Assembly. In 1985 the General Assembly of the UN pointed out that there may be some cases in which the perpetrators may be pushed to terrorist acts by violation of the human rights; it also urged Nations and the UN organs to make contributions to the progressive elimination of any causes underlying international terrorism. Sri Lanka is one of the examples where the UN failed to fight terrorism; this is clear in that the Sri Lanka government was able to reduce the LTTE power from being a formidable organization to a mediocre organization. The LTTE is one of the most cruel and ruthless terrorist groups that can use any weapon to cause mass destruction of property and loss of life. The UN took no action to try and bring to an end the LTTE group of terrorists but fortunately the Rajapaksa government succeeded in defeating the LTTE. The main objective of the UN is to settle disputes between countries by use of diplomatic approaches before the countries decide to use military force or before the conflict becomes uncontrollable. Unfortunately the UN has not attained this goal. The UN is a forum where member states send representatives to argue for or against their countries. These representatives have been seen to be just spokesmen for their country but back in their country they do not have any power or influence. Another issue is that those countries that are ruled by dictators or those that are not at peace use the UN debates to delay and complicate issues in their favour. Over the last fifty years during the existence of the UN the debates have not resolved any issues but threats, direct military action and hidden negotiations that were not sponsored by the UN have had positive changes in solving most of the conflicts. An example of this is the case of Iraq which was under the UN forces for over 100 years during which the Iraqi people were subjected to sufferings while on the other hand Saddam Hussein continued with his dirty games with the UN of only allowing inspection of weapons of mass destruction at certain periods and also coming up with solutions to the oil for food agreement imposed by the UN. This stalemate was broken by the United States of America by invading and overthrowing the Saddam regime. Had this stalemate not been broken the people of Iraq would still be under the oppressive rule of Saddam. The UN has also been unable to take actions that are direct and independent without seeking the support of its members. In the current world which is full of oppressive regimes and war mongering dictators who understand that the UN lacks any real power therefore making them free to do anything they want. For example the North Korea has been testing nuclear weapons and it has currently threatened to do it again while the UN is just considering an act of sanctions. If North Korea today decides to use the nuclear weapons in an act of terrorism many people would end up losing their lives just because the UN failed to take action in time. The member States of the UN should then be urged to contribute equal military force or money that is equivalent. The UN should then have these resources at its disposal and it should be free to use it without any approval from any of its member states. There are 5 selected member countries of the UN that can disagree on any decision that the majority of the States had agreed upon. These countries are China, USA, Russia, United Kingdom and France because they founded the UN that came up with the rules of UN after the Second World War. This has resulted in a lot of problems in the UN because these countries with the veto power were not elected democratically and therefore there is reason to believe that the decisions that the countries take are truly biased. This is a problem that has greatly caused people in this world to lose lives and it is not aimed to come to an end any time soon because the countries with the veto power are not willing to give up this power and allow for fair selection. The other failure of the UN is that most of its members are not countries geared towards peace and have questionable voting practices. The only solution to solve this problem would be to deny such nations the power to voting during any meetings of the UN. This is not easy to implement because countries debate in the UN forum only if they have the right to vote in the UN Security Council. UN considers itself a humanitarian body while on the other hand it continues allowing non-humanitarian countries like China to vote on humanitarian issues. The other area where the UN has failed to take action on terrorism is by the fact that UN does not formally recognize any State as a terrorist. Terrorists on the other hand would not debate in a public forum like the UN or seek help from the UN to sort out their issues and this clearly shows that the UN does not get involved in any way with the terrorists. Due to this the UN has been seen to be completely blind to terrorists and it has no intentions of addressing the terrorists and this is not likely to change soon. UN being the largest organization in the world that promotes peace should not be completely unable to address terrorism and therefore this has been seen as a complete failure to the UN in fighting terrorism. The United Nations has also been seen to fail in the action against terrorism because it has for a long time been unable to clearly define terrorism without putting policies that would annoy some of its strongest member states. UN has found itself in a state of confusion as Islamic states argue that the fight against occupation should be exempted from the definition of terrorism as this is well stipulated by the UN in the Organization of Islamic Conference (OIC) of 1998 which clearly states that the struggle of the people either peaceful or armed struggle against any foreign occupation shall not be termed as an act of violence. The issue of terrorism as been complicated more by the fact that the struggle of the people to free themselves from any foreign occupation and/or colonialism does not in any way constitute an act of terrorism. Some of the Islam clerics have also considered the presence of the US and other foreign forces in Afghanistan and Iraq as occupation and therefore they do not term any act of the citizens of this country to free themselves from foreign occupation as an act of terrorism. Due to lack of a definition of terrorism there has been failure of the UN to come up with a complete detailed convention on international terrorism but instead it has adopted a document it calls Global Counter Terrorism Strategy which is based on an unknown definition of terrorism. In conclusion the UN has failed in many areas in the fight against terrorism. For the UN to fight terrorism globally it should be in a position to address terrorists and come up with ways of preventing anymore loss of lives. The UN should also understand that the terrorists are people who can be negotiated with and therefore coming with a democratic solution for both sides. UN should also stop involving member states that are not humanitarian in any humanitarian issues. In general the World requires a stronger peace international police who will be free to act without getting orders from any of the UN state members.

American History X Essay Example for Free

American History X Essay American History X is a film that centered on two brothers and how their lives changed when their father died. The story revolved around discrimination and racism. But most importantly, the movie emphasized the capability of an individual to change. The main character, Derek Vinyard, transformed into a racist when his father died â€Å"in the line of duty by a minority† and when he killed two black men who tried to rob him. Before he entered prison, Derek had already a preconceived notion that Blacks were menace to the society and that the Whites were the superior race. However, inside the penal complex, he found out that â€Å"there is good and bad in every race. † So to prevent his younger brother, Danny, from committing the same mistakes, Derek encouraged him to be open-minded and disregard all the things that were inculcated to him when they were members of the Neo-Nazi group (IMDb). This movie was able to show three sociological concepts namely: differential association, racism and social inequality. Differential association is a learning theory which focused on the processes by which individuals come to commit criminal acts (Hamlin). In the film, this was shown when Derek joined the neo-Nazi group; he started to adapt a more delinquent lifestyle like thrashing the local grocery store. Meanwhile, racism is defined as the idea that race sets the difference in the personality or competency of an individual which results to some race being better than the others (Eckert). This concept was portrayed when Seth and Danny were having a conversation. Seth asked Danny who he hated and Danny replied, â€Å"I hate anyone that isnt white Protestant. Theyre a burden to the advancement of the white race† (Kaye). Lastly would be social inequality which refers to the â€Å"ways in which socially-defined categories of persons (according to characteristics such as gender, age, ‘class’ and ethnicity) are differentially positioned with regard to access to a variety of social ‘goods’ like education† (Centre for East European Language-Based Area Studies). In the movie, this was represented when two Black guys were trying to steal Derek’s truck. This shows how some races are well off than the others because they have better jobs, houses and benefits. I think American History X is an eye-opening film about the presence of discrimination, prejudice and hatred in the society due to difference in race. More so, the movie tried to relay the message that delinquency is learned and it can be unlearned if an individual is put in a better environment. When Derek went to prison, he realized that race was not a major issue that separated one individual from another; it was more on how a person presented himself/herself to a group. In the end, it would always be every man for himself in this dog eat dog world. Works Cited â€Å"American History X. † 2009.

Impact Of Mobile Technology For Students Information Technology Essay

Impact Of Mobile Technology For Students Information Technology Essay In todays world mobile devices are used as not only for communication tool but also it is used as other purposes like instant mail, uploading photos, SMS and digital library. In 19th century mobile are introduced only for voice call but now there are many features are implemented in the mobile devices so they can communicate and gets entertainment with new mobile technology like games, internet, mp3 player and videos. People can use mobile devices with new technology and they can use their mobiles in this way. According to Hosny, Mobile devices are of many types such as cellular phone, ipods, PDAs, wireless data networks and Bluetooth devices which are presently in the market. There are many mobile technologies which are used in the mobile education which are very helpful to the university students. The technologies are Global System for Mobile communication (GSM), SMS, Wireless Application Protocol (WAP), 3G technologies, Bluetooth technologies and XML these are technologies which are used in the Mobile education. WAP, this technology is used in the mobile to connect the internet and access the internet. 3G technology provides high range of bandwidth so user can access the data very fast and efficiently. 3G phones provides in such way that mobile can be used as computer as we can see TV and read newspapers and digital books. XML language is a Meta language that communicates the data. It is used mainly to develop mobile applications. Introducing mobile technology like smart phones and e book readers in mobile devices helps the students a lot. Students can use their laptops in a particular environment like universities and classrooms but they can use their mobiles where ever they can. E books are those which are in digital form they can download and access the e books through their mobile devices. As these devices are portable and now a days most of the mobiles have Wi-Fi technology students can use their mobiles for personal use no one cannot use their mobiles without their permission. Students cant take laptops from one place to other every time. Students can use their mobiles for on-line bank transactions. Video streaming can also be accessed by using separate software in mobiles. Now implementation of new technology like Bluetooth they can share files from one mobile to other mobiles (Ling et al, 2002). With the new technologies that are implemented in the mobiles devices (blackberry and i-phone) are very useful for the university students. With Smartphone students can access e books that are very useful for education purpose and its time consuming. All the time students cant go the university library and access their computers. Students can store the course content information in their mobiles and retrieve the information about their course. When students are travelling in public transport if they want any information regarding student support services they cant open their laptops conveniently and cant access the internet but they can use their mobiles conveniently. As mobiles are light weight they can take with them anywhere. The main advantages of mobiles are they are not hyperlinked and they are network shared so people can access the data very easily. Students cant talk chat or video conference in flexibly because its private for them but students can chat with their mobiles mo re flexibly with their mobiles. Mobile learning is very useful to the university students because if students fail to attend a particular reason he can directly access the lecture in their mobiles but university must implement this technology so that students can benefit. Mobile learning helps the students to be flexibly in their learning. There is also disadvantage of mobile learning because university students cant to some practicals such as labs related to the electronics, VLSI labs, networking related labs. So students can start learning in mobile but not able to electronics and network related practicals. if they cant attend the university this shows negative impact on their studies and also people cant access more e books in mobile because of less memory (nor et al, 2006). Students who are using mobiles in high school stage can have negative impact on their studies and cant concentrate on their studies. High school students can misuse the mobile technology because they are very crazy about new technology mobiles. School students can easily addict to the games that are implemented with new technology (animated, bike racing etc) that will show a great negative impact on school students. School administrators should take care of not using mobile phone in their school because they cant concentrate on studies in the class room. Parents should take care of their children by not using mobile phones in nights if they addicted to mobile games they will not sleep in time and fell full stress when they get up in the morning. Mobile technology helps business people more compared to other category of people because business people travel more from one place to other place of business purposes. If there is no wireless networks in which they are travelling it is very difficult to access internet if they is also having laptops with them but there is no problem with the mobiles to access internet as mobiles are network share connectivity. Business people, if he is higher official in the organization if he cant give correct information related to business issues when is travelling this will lead to many problems in the organization but he can solve problems by new trend of mobile technology. According to the hosny and pagani all of them are mentioned about the positive impact of the mobile technology but there are many negative impacts of mobile technology. But people who are not aware of new technology cant use of mobile technology. If mobile phones are stolen all the sensitive information that can be taken that leads to many problems especially to business people. They mainly focused on advantages of mobile technology and they should have also focused on the disadvantages of the mobile technology (Hosny , 2007). 1.1 Draw Backs With the Mobile Technology for Students By using this, mobile phones emit microwave radiations to communicate with each other. By accessing internet in the mobiles there is scope virus threat which can affect the mobile devices and can lose the important data. Students can addict in using this technology which shows negative impact on their studies. While driving their vehicles people who are using mobile phones must be kept aside if they use those leads to accident sometimes. 1.2 Project Outline Research approach I follow to do my research is deductive approach. Qualitative method is used to study this research by conducting group of interviews to the people like university students, high school students and business people. I will collect the data by conducting In-depth interviews to university students and focused group interviews to high school students, common people and business people. I will select the university students because they can use the mobile technology more for education and entertainment purposes and high schools students because they are very crazy for use of mobile phones and business people because they use mobile phones for their business needs. I will collect the data from the different people how the mobile technology is used in their daily life. Qualitative method: I will conduct In-depth interviews to the university students and prepared some set of questionnaires which are yet be asked in the interview and I will use tape recorder as data collection instrument to collect the data from the university students. Data that I collected from the different people is answer to what is the impact of mobile technology on the students. Many university students have so many benefits of mobile technology and many students have some problems in using mobile technology. Implementation of mobile learning in the universities is a good idea to implement m-learning in the universities. Through m-learning, university students can listen to lecture class or tutor sessions through mobiles by using m-learning technology but students cant get the practical knowledge. With the introduction of GPS system in the mobile devices they can track any information about the university but it needs permission from the university but information can be acces sed for the particular student who is studying in that university. Many students use their mobiles only for entertainment and social networking websites and they could not be used as mobile education purposes. Students can lose their mobiles very easily and the important information can be lost with mobile it leads to many problems for the university students. Some students use their mobiles only for their daily life use but not for other purposes because they are not aware of new technology (Hosny, 2007). School students can use their mobile only for chatting, SMS and playing games with mobiles. Mobile technology cant be used for the education purpose because they cant concentrate on studies with the mobiles and they are diverted to entertainment purpose with those mobiles. I think school students use their mobiles only for playing games when they are free and not for any other purposes. Most of the students are not aware of the new technology and what software used in their mobiles. Common people who are using mobiles cant spend their day without the use of mobiles. Some common people who are working can listen to songs and play games in their mobiles when they are bored when they are travelling in public transport and some applications in their mobiles benefit a lot. Some of the old people can spend their day without the use of mobiles and by using mobiles they can have some impact on their health because of radiations from the mobile phones. There are many problems with this newly invented mobile technology because people are not aware of these new technologies and sometimes they can misuse these mobile technologies. Mobile battery should be manufactured in such way that battery should be charged so that users can use enjoy the applications in the mobile devices. Low effective battery cant give much life to the mobile devices. Security is main concern for every technology. If they dont provide more security, users cant buy mobiles which provide less security (Sattler et al, 2010). 1.2.1 Aim and Objectives Aim: The main aim of this paper is to do a proper research on the impact of mobile technology on the students daily life. Objectives: One of the objectives of this paper is to analyze the usage of mobile technology on the students. To find how mobile technology had impact on the people in the present world. To do a proper research on the mobile technology on all types of age people. Main concentration is how students are using the mobile technology whether they are having the good impact or bad impact on the students. 1.3 Research Questions Is mobile devices has the technology that supports mobile learning? How often do you use regularly students use mobile device (like using internet, MMS, SMS etc) for your course activities in class room in a day? 1.4 Deliverables: How Mobile technology has impact on the students Information which is gathered from the students need to be arranged in the structured format. Later on concentrating on each review proposed to do a research based on the opinions which matched mostly. Different types of method are concentrated on doing the research on the students. Suggestions are noted from the students on the impact of mobile technology. Previous researchers data related to the impact of mobile technology on the people need to be concentrated. 1.5Evaluation The new generation people are very much attracted to the web based resources, social networking and digital media. As the people are grown with the web especially students must be encouraged to use of mobile technology in their university campuses so that they can again diverse range of experience. Only some of the students are using new mobile technologies and other students are using only for making phone calls. Students who are not following the traditional process of learning mobile learning are very useful to those students. The main advantage of the mobile learning is students can access anywhere and at any time. Mobile technology is less cost effective compared to other technologies. Students can use SMS to answer there Quiz questions online with new SMS server is implemented in mobile devices this helps the students so that they can answer all the questions at any time instead of sitting at one place. But there are some problems with this as mobile devices have small keypad i t is difficult to type and they can enter wrong characters it leads to problems. People who are living in the rural areas can again many benefits by using mobile technology because in rural areas they cant have the broadband connection. People who earning less income and people who wants to save money they can use mobile technology as it is very cheap compared to other broadband technology. Compared to computers and laptops, mobiles have disadvantage because they have small screen resolution, less memory and battery life is low. This will show impact on mobile educational application which in turn affects the students. Mobile learning helps the students to be focused for long time, can raise their self confidence and can experience more learning on individual modules. 1.6 Research Methodology The procedure in which the information is collected and handled in the process of designing the desired system is the research methodology. The information set for the purpose of research can be generally categorized as: Qualitative research and Quantitative research. Qualitative research is defined as the research which aims to develop the understanding of how and why individuals and group of persons (social world) operate in a particular approach. Whereas the Quantitative research is defined as the research implicated or interested with the examining entities where the prevailed observations and measurements can make without prejudice and repeated by investigators. .

An Analysis of Wilburs Mayflies Essays -- Wilbur Mayflies Essays Poet

An Analysis of Wilbur's Mayflies      Ã‚  Ã‚   Richard Wilbur's recent poem 'Mayflies' reminds us that the American Romantic tradition that Robert Frost most famously brought into the 20th century has made it safely into the 21st.   Like many of Frost's short lyric poems, 'Mayflies' describes one person's encounter with an ordinary but easily overlooked piece of nature'in this case, a cloud of mayflies spotted in a 'sombre forest'(l.1) rising over 'unseen pools'(l.2),'made surprisingly attractive and meaningful by the speaker's special scrutiny of it.   The ultimate attraction of Wilbur's mayflies would appear to be the meaning he finds in them.   This seems to be an unremittingly positive poem, even as it glimpses the dark subjects of human isolation and mortality, perhaps especially as it glimpses these subjects.  Ã‚   In this way the poem may recall that most persistent criticism of Wilbur's work, that it is too optimistic, too safe.   The poet-critic Randall Jarrell, though an early admirer of Wilbur, o nce wrote that 'he obsessively sees, and shows, the bright underside of every dark thing'?something Frost was never accused of (Jarrell 332). Yet, when we examine the poem closely, and in particular the series of comparisons by which Wilbur elevates his mayflies into the realm of beauty and truth, the poem concedes something less ?bright? or felicitous about what it finally calls its 'joyful . . . task' of poetic perception and representation (l.23).      Ã‚  Ã‚  Ã‚  Ã‚   In this poem about seeing from the shadows, the speaker?s revelations are invariably ironic.   What could be a more unpromising object of poetic eloquence than mayflies, those leggy, flimsy, short-lived bugs that one often finds floating in the hulls of rowboats?   Yet for Wilbur... ...vocal statement about the ?organic? possibilities of poetry than optimistic readers might have expected. ?Mayflies? forces us to complicate Randall Jarrell?s neat formulation.   Here Wilbur has not just seen and shown ?the bright underside of? a   ?dark thing.? In a poem where the speaker stands in darkness looking at what ?animate[s] a ragged patch of glow? (l.4), we are left finally in a kind of grayness.  Ã‚   We look from darkness into light and entertain an enchanting faith that we belong over there, in the immortal dance, but we aren?t there now.   We are in the machine-shop of poetry.   Its own fiat will not let us out completely.    Works Cited Jarrell, Randall. ?Fifty Years of American Poetry.?

Achilles Shield :: Free Essay Writer

  Ã‚  Ã‚  Ã‚  Ã‚  Achilles’ shield, made by Hephaestus, the god of fire, plays a part in the Iliad. It tells the story of the war between the Greeks and the Trojans. Hephaestus depicts the two cities and the activities going on in them, and Agamemnon’s, the Greek’s king, estate. Homer thought that seeing what it is on the shield could help the reader understand the importance of Achilles' shield and the Iliad. Hephaestus used fine metals and put lots of scenes of things going on not only in that time period but also in respect to the Iliad’s plot. Hephaestus went into great detail in the cities; especially what mood and what people were feeling.   Ã‚  Ã‚  Ã‚  Ã‚  Hephaestus used bronze, tin, gold, and silver to make the shield. The shield has five layers of metal. On the shield are scenes showing the heavens, earth, sea, two cities (a Greek one and Troy), Agamemnon’s estate, fields, a vineyard, a herd of cattle, and people dancing and being merry.   Ã‚  Ã‚  Ã‚  Ã‚  The two cities on the shield represent a city in Greece and the city of Troy. One of the cities is filled with men dancing and singing, and brides in the streets. The other city has an army surrounding it. There is Turmoil around both of the city. In one two armies fight, Greeks and the Trojans, along the river banks killing many men. Both cities are tainted with death, but at the same time both have love in them. In one city, the Greek one, two men, possibly Achilles and a fellow comrade, fight over the consequence for the murder of a warrior and take their case to a judge, could be Zeus in the Iliad, to decide the punishment. In the other, children and wives stay and watch the house and each other as the men go to war. This scene is meant to parallel to the Trojans leaving to fight the Greeks.   Ã‚  Ã‚  Ã‚  Ã‚  Agamemnon's estate is also depicted on Achilles' shield. Plentiful harvests of grain are shown along with Agamemnon standing silently among the barley. An ox is also shown being killed for a feast. The shield represents happiness and prosperity for Agamemnon which also foreshadows the Greek's victory over Troy.   Ã‚  Ã‚  Ã‚  Ã‚  Finally, the shield showed a vineyard with many workers who pick the grapes. One is a young boy who loves to sing and play a lyre. A herd of cattle is also illustrated.

Cryptography :: Exploratory Essays

Cryptography Cryptography is the science of preparing communication intended to be intelligible only to the person possessing the key or method of developing the hidden meaning by cryptoanalysis using apparently incoherent text (Encarta Encyclopedia). The movie mercury rising is a good example of cryptography. It’s about a little boy who is autistic. The little boy can do puzzles such as cryptography easily. One day while on the computer the boy cracks a highly secretive government code. The governmental agency wants the young boy found and killed for cracking the code it took years to write. Cryptography started a long, long time ago with Julius Caesar. When he wanted only his people to know something he used cryptography. He did this by replacing A’s with D’s, B’s with E’s, and so on down the alphabet. This was known as "shift by 3", for obvious reasons. The Jewish writers also used a code of their own called Atbash. They did it by reversing the alphabet, they used the last letter of the alphabet in place of the first, the next to last for the second, and so on. Atbash is exemplified in the Bible, Jeremiah 25:25, where "Sheshech" is written for Babel (Babylon). As you can see, cryptography has been used for many years and is continuing to become more high tech. The term cryptography is sometimes restricted to the use of ciphers, that is, to methods of transposing the letters of plain text (unencrypted) messages, or to methods involving the substitution of other letters or symbols for the original letters of a message. And to various combinations of such methods, all according to prearranged systems. Ciphers of various types have been and can be devised. All of them fall into to one of two categories, transposition and substitution. In transportation ciphers, the message is usually written, without word divisions. They are rows of letters arranged in a rectangular block. The letters are then transposed in a prearranged order such as by vertical columns, diagonals, or spirals. There are two types of ciphers, simple and complex. In a simple substitution cipher is particular letter or symbol is substituted for each. In a multiple substitution (polyalphabetic) ciphers, a keyword of number is employed. And in more complicated polyalphabetic systems, the letters of the keyword may tell which of a series of mixed substitution alphabets is to be used to encipher each letter of the message.

Atbash is exemplified in the Bible, Jeremiah 25:25, where "Sheshech" is written for Babel (Babylon). As you can see, cryptography has been used for many years and is continuing to become more high tech. The term cryptography is sometimes restricted to the use of ciphers, that is, to methods of transposing the letters of plain text (unencrypted) messages, or to methods involving the substitution of other letters or symbols for the original letters of a message. And to various combinations of such methods, all according to prearranged systems. Ciphers of various types have been and can be devised. All of them fall into to one of two categories, transposition and substitution. In transportation ciphers, the message is usually written, without word divisions. They are rows of letters arranged in a rectangular block. The letters are then transposed in a prearranged order such as by vertical columns, diagonals, or spirals. There are two types of ciphers, simple and complex. In a simple substitution cipher is particular letter or symbol is substituted for each. In a multiple substitution (polyalphabetic) ciphers, a keyword of number is employed. And in more complicated polyalphabetic systems, the letters of the keyword may tell which of a series of mixed substitution alphabets is to be used to encipher each letter of the message.
