In what way has science and technology advanced medicine since 1750 (12 marks)
Science and technology has advanced medicine since 1750 because of the discovery of DNA. James Watson and Crick started working together on studying the structure of DNA whilst at the same time Maurice Wilkins and Rosland Franklin in London were using X-ray diffraction to study DNA. Crick and Watson used their findings on their own research and in April 1953 they published the news of their discovery, a molecular structure of the DNA based on all of its features. Their model served to explain how DNA replicates and how hereditary information is coded on it. This set the stages for rapid advances in molecular biology which continues until this day. In the other partnership with Rosland and Franklin, Franklin produced an X-ray photo that allowed Crick and Watson to work out the 3D structure of DNA. The structure of the DNA was found to be a double helix. Watson, Crick and Wilkins shared a Nobel peace prize in medicine in 1962. Franklin had died in 1958 and despite her hard work the prize could not be received posthumously.
Another way in which science and technology advanced medicine since 1750 was the development of penicillin. In 1928, Alexander Fleming whilst studying influenza noticed that mold had developed accidently and completely by chance on a set of culture petri dishes used to grow staphylococci germ. The mold on the petri dishes created a bacteria free circle around itself. He then experimented further and made the mold into some sort of medicine and named the substance penicillin. Fleming wrote down his discovery and published it. However, Fleming did not realize the potential of this remarkable discovery of a drug. Therefore, no further research was carried out due to lack of funding and specialist help. Howard Florey and Ernest Chain decided to further develop Fleming’s…...

Defining Science, Medicine, and Technology

...What is Science? Science is the collective human effort to better understand the history of the natural world and how it works, using the basis of observed physical evidence to derive this understanding. It is done through experimentation using simulation of natural processes under controlled environments. An ecologist observing the territorial behaviors of bluebirds and a geologist examining the distribution of fossils in an outcrop are both examples of scientists making observations in order to find patterns in natural phenomena. They just do it outdoors and thus entertain the general public with their behavior. A primary aim of science is to collect facts. What Is Medicine? The term medicine is used to refer to the science of healing, as well as any substance that is used to treat diseases and promote health. Today there is a variety of different health care professions that use medicine as a tool to improve and maintain health. The use of medicine and plants with medicinal properties has taken place since the prehistoric times when people believed that herbs and animal parts could help heal sick and injured people. Many countries around the world such as Egypt, India, Persia, and China have been developing traditional medical practices for hundreds of years. Since then the use of medicine has become greatly intertwined with most people’s lives and it is often used on a daily basis by many people in order to help with things such as lowering blood pressure or......

Science and Technology: Advantages and Disadvantages

...Science and Technology: Advantages and Disadvantages Technology is a very broad concept and is used to refer to several braches of science and study. There are many advantages due to science and technology but there are also many disadvantages. Science and technology have a great impact on everyday life and several people thrive to continue discovering the best technologies. It has brought many advantages in healthcare, medicine, education, and communication to help improve the life of mankind, but mankind could also be too dependent on technology and could fall into the wrong hands. There are obviously more advantages than disadvantages. One of the biggest discoveries in science and technology is the mobile telephone. With phones we are able to talk to any person in the world, we can now also see the person we are talking to. Video calling is very popular now among companies. With the invention of video calling companies can now connect to other countries and expand their companies, which mean more jobs for the poor and unemployed. With all the new smartphones and programs on cell phones people can now conduct business anywhere and anytime. Also, cell phones now have GPS which means a parent can choose to give their children a phone and be able to track them anywhere they go (Mazar, 2011, para. 4). I can’t even remember a time when I didn’t have my cell phone in my pocket. Doctors even use smart phones to look up symptoms and treatments faster. As I was sitting in......

In What Ways Has Marxism Developed Since Marx’s Death?

...philosopher of all time. His idea on life, society and social structure revolutionized the ways in which people think and still holds much relevance in today’s society. Although there were many downfalls within his thinking he still set out the basis of Communism within Russia. Marx drew distinctions between the bases of his own contemporaries and his own scientific theory of which he believed were firmly rooted within society. He believed that social change was needed in order to achieve a better society for everyone and in order to achieve social change there must be class conflict. Marx’s major concern for social change was economic change and his most famous work dealt with the issues of class conflict and the opposition between the capitalists/bourgeoisie and the working class. During that time it was the bourgeoisie who were responsible for the controlling of land and factories whereas it was the working classes who were being exploited by the higher classes. One of largest manuscripts that Marx produced was The Grundrisse which discussed issues such as the capital of labour, wages and property and was not published until after his passing. Marx is considered to be one of the founders of communism, modern socialism and sociology and following his death the development of socialist thought. Since the death of Karl Marx the development of his Marxist ideals has continued to evolve and has lead to many other such theories. Some believe that the idea of Marxism is past......

...this time the technology involved progressed enormously: Scientific calculators started to emerge with more and more functions. Programmable pocket calculators came on to the market, capable of storing programmes and instructions. As the years went by, calculators had more and more features and were capable of a great deal. The Ethernet was a step forward from the Arpanet. It was developed in the early 1970s as a method of transferring data over Local Area Networks (LANs). Its emergence is usually attributed to Robert Metcalfe, who wrote a paper with his assistant David Boggs entitled ‘Ethernet: Distributed Packet-Switching for Local Computer Networks'. The next advancement was the creation of the internet. A major step forward in 1986 was the NSFNet (National Science Foundation Network), created as the backbone of a university network. Even in the 1990s, people had to sign an agreement with them in order to access large parts of the public internet. Tim Berners-Lee (whose parents were both mathematicians on the Manchester Mark 1 project) is the man responsible for the creation of the World Wide Web (WWW). He saw the potential of hypertext coupled with the internet and in August 1991 he created the first ever website, which has been archived here. From this point onwards, the internet and WWW took on a life of their own. Their own huge advancements made progressions in hardware all the more important. It has indeed made the world a smaller, yet more advanced......

Advanced Technology

...------------------------------------------------- 2G, 3G and 4G TECHNOLOGY 2G Technology 2G refers to second generation wireless telecommunication technology. While its predecessor, 1G, made use of analog radio signals, 2G uses digital radio signals. Based on what type of multiplexing is employed, 2G technologies may be categorized by whether they are based on time division multiple access (TDMA) or code division multiple access (CDMA). Code division multiple access is a digital radio system that transmits streams of bits (PN Sequences). It permits several radios to share the same frequencies. Unlike time division multiple access, all radios can be active all the time, because network capacity does not directly limit the number of active radios. Since larger numbers of phones can be served by smaller numbers of cell-sites, CDMA-based standards have a significant economic advantage over TDMA-based standards. The main 2G TDMA standard is: * GSM (Global System for Mobile communications)--is the most popular standard for mobile phones in the world. GSM accounts for over 80% of all subscribers around the world. It makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world. GSM differs from 1G in that both signaling and speech channels are digital. The main 2G CDMA standard is: * IS-95 (Interim Standard 95) is the first CDMA-based digital cellular standard pioneered by Qualcomm....

In What Ways May Disagreement Aid the Pursuit of Knowledge in the Natural and Human Sciences?

...argue about evidence or go out and seek new evidence.” This quote captures the essence of what this essay is going to cover. Disagreement opens room for questioning and reasoning.. In order to make the knowledge question that entitles this essay easier to understand, the “pursuit of knowledge” needs to be defined. The pursuit of knowledge is a famous term to define the inherent concept of humanity’s constant desire to know more. Personally this topic appeals to me as I have seen the substantial curiosity that children possess, but I believe this thirst for knowledge is very limited. All children want to hear is an answer, but they don’t question the sources or ask to see the evidence. When I noticed this trait in young children, I had an epiphany that if our global society followed this childish outlook on the world, the world and the education system wouldn’t be the same. I will elaborate upon two possible perspectives towards this question; either you believe that disagreement does aid the pursuit of knowledge or you believe that it doesn’t. I will demonstrate both perspectives by analyzing how the roles of logic and emotion help gain new knowledge in the sciences. Ideally the role of logic is applied towards the natural sciences, and the human sciences use emotion as a way of knowing. I believe that disagreement in the natural and human sciences opens up the opportunity to question what has been asserted, in order to ameliorate our current Truths, but there are cases......

In What Ways, If Any, Has Globalization Transformed the Phenomenon of Terrorism?

...In what ways, if any, has globalization transformed the phenomenon of terrorism? Introduction The idea of terrorism has not always been as it is today. The word “terror” originated after the French Revolution and the word “terrorism” was subsequently recorded by the Académie Française in 1798 (Roberts 2002). The regime of “la Terreur” was one of force and bloody repression against opponents to the newly born French Republic, but since the 19th century, terrorism has come to designate a method of opposition used by small groups (Tilly 2004, 8-9) “against the legitimacy of the prevailing sovereign power” (Scruton 2002, 126). As Barkawi (2006, 129) aptly puts across “‘terror’ is often used as a weapon by those who lack sufficient weapons to fight a military war, who believe their voices are not being heard and their desires bear no fruit”. Contrary to the French “terror”, “terrorism” is then no longer a practice of the State; it is that of radical groups opposing the State, and it is mainly the State that gives them this name (Townshend 2002, 3); the names these groups give themselves are in relation to a cause they see as legitimate. Such causes have arisen in numerous places, prompting some to take extreme but in their minds justified action, and Europe has faced terrorist threats long before the 9/11 attacks, incarnated by the Irish Republican Army (IRA), the Basque Fatherland and Liberty group (ETA) in Spain or the Red Brigades in Italy, to name only a few......

What Has or Has Not Changed Since 1985?

...recognized with their roles as men but were just part of men as an attachment. They were seen as unclean and the source to sin. When they realized in understanding how unfair they've been addressed and inferior to men, some opponents started to use what's said in the bible against them on their wishes. Women however continue to realize how they were limited to many aspects of life but they were still undervalued and even the bible says and support it in a way that the head of a woman is her husband. This makes women less equal than men. Moreover, concern about equality was another issue women experienced then in the early centuries. Feminist began to promote "women studies" as women's experience was important. Women were seen as secondary while men had to lead everything in society. They were treated as minority in society and didn't have the chance of studying as men and all their studies were remedial. However, in God's world, women were still not cleared to claim their equality. In the early nineteenth century, women remembered what had been left out and began to serve themselves for their need. They expanded their knowledge. With their studies, their discoveries were freely shared and began to experience equality in their community. However, after women were not able to participate as majority but were classified as minority, with the movement from women's studies to feminist studies, there were some changes that happened. They came to gained more and new knowledge.......

Examine Some of the Ways in Which Marxists Explain Crime- 12 Marks.

...One way in which Marxists examine crime is the idea that they feel crime is inevitable in capitalism because capitalism in itself is criminogenic. Due to capitalism being based on exploiting the working class by using them as a means of making profit, this is therefore damaging to the working class and arguably explains why crime is committed. Due to the exploitation of the working class, which may lead to poverty and in some cases the only way to survive poverty, is by using crime in order to feed and clothe families. Crime may also be the only way the working class can compete in this world of consumer goods, encouraged by capitalist advertising, resulting in theft and robbery. Lastly the lack of control the working class have on their lives due to being controlled by their capitalist bosses and government can lead to frustration in the working class which in some situations can only be vented through violent crimes and vandalism. However this theory is criticised as not all crime is committed by the working class and this theory does not take into account white collared crime such as tax fraud, therefore Gordon argues that crime is a rational response to the capitalist system and is therefore found in all social classes, even if the statistics say otherwise. Another Marxist idea that helps explain crime is Selective Enforcement. This is the idea that some Marxist do except that crime is widespread over all classes but the way in which the criminal justice system is applied...

Science and Technology

...Science and Technology Essay 4 (250 words) Science and technology has become a debated topic in the society. On one hand, it is necessary for the modern life where other countries are continuously developing in the field of science and technology. It becomes very necessary for other countries too to grow in the same way to be strong and well developed like other countries for the future safety and security. It is science and technology which helps other weak countries to develop and be strong. We have to take support of science and technology forever to improve the way of life for the betterment of mankind. If we do not take the help of technologies such as computer, internet, electricity, etc we cannot be economically strong in the future and would be backward forever even we cannot survive in such a competitive and technological world. Advancement in the field of medical, agriculture, education, economy, sports, games, jobs, tourism, etc are the examples of science and technology. All such advancements show us that how both are equally beneficial for our life. We can see a clear difference in our life style while matching the ancient and modern way of life. High level of scientific and technological advancement in the field of medicine has made easy the treatment of various lethal diseases which was earlier not possible. It has helped a lot to the doctors to find effective ways to cure diseases through medicine or operations as well as research vaccines to cure diseases......

To What Extent Has the British Constitution Been Effectively Reformed Since 1997?

...great deal was left undone. The question since then is how much has the constitution been reformed and how positive effect these reforms have had. There is no doubt that the HRA has transformed Britain. It created a means by which government and other bodies could be prevented from abusing our rights. The courts were given powers to enforce rights. This has meant that we now have more privacy and have the right to be treated equally under the law. However, the HRA was not made biding on Parliament and so governments can still abuse rights. This has been seen with anti-terrorism acts which give the police great powers including the ability to arrest suspects without trial. The HRA also does not protect us against the growth of surveillance and stop search powers or the prevention of some demonstrations. Similarly, the FOI act has been partly effective as it enabled us to know about the MP’s expense scandal and other aspects of government. However government can still conceal sensitive information thus perhaps the act should have been stronger. The introduction of Devolution as well supported in Scotland and Wales has made a huge difference in those countries as well as in Northern Ireland, the people of those countries support it and have demanded more. Thus the main issue is that devolution did not go far enough perhaps. As some also suggest that there should be proper federalism for these countries to have true independence. So it has been effective in decentralising......

What Is Science and Technology?

...MST 4, 1st assignment Date: 06/19/12 KARL JUSTEEN CLORIBEL DAVID What is science? What is technology? How do they impact or mold society? Science is a sustained intellectual activity carried on by human beings that is designed to discover and test information with regards to the physical and natural behavior of everything observable, testable and collectible data that can be organized into meaningful patterns. Information is the primary goal of science. To be able to answer and explain every inquiry is the rational nature of man, therefore, through time, man has devised a systemic process by which he can examine and discern the order and relationships that exist between and amongst various branches of knowledge. Science therefore is any systematically organized body of information on any subject matter. Developing countries, such as the Philippines, constantly pursue new knowledge and techniques to further our progress with the help of scientific process and observation. Though the several branches of science apply to all nations and all types of societies, Philippine science tend to focus more on the natural and economical departments, as we are a very naturally rich location. The Department of Science and Technology is the governing body of scientific activity in the country, responsible for organizing, recognizing, and enabling every scientific study to reach its most beneficial purpose. It has been the core of scientific progress in the country. A novel once...

To What Extent Has the Use of Technology in Evidence Altered Our Understanding of Adversarialism?

...Evidence To what extent has the use of technology in evidence altered our understanding of adversarialism? What is adversarialism? The adversarial system is the two-sided structure under which criminal trial courts in the UK operate. There are four prominent structural features of the English adversarial system. Firstly, the parties dominate the conduct of proceedings with the judge playing a relatively passive role. Secondly, the parties are free to choose the terrain on which to fight out their legal battles and to select their forensic weapons. Thirdly, Trials are continuous, oral and public events. Fourthly, the imbalance of power between the state and the accused is ameliorated by rules and principles reducing inequality of arms. High level definitions or at least descriptions of the adversarial system abound such as that of Lord Denning in Jones v The National Coal Board.They are all to the effect that the judge is a passive and neutral umpire who cannot descend into the arena for fear of having his or her judgement clouded. The adversarial system is said to be the most efficient means of arriving at approximate truth because it harnesses the power of self-interest on each side to unearth the best evidence. Similarly the best legal arguments are thought to emerge from the clash of advocate’s submission on the law. A classic quotation is that of Lord Eldon in Ex Parte Lloyd that ‘truth is best discovered by powerful statements on both sides of the question.’......
