Brain mapping is a latest neuroscience technology which relates the structure and functions in the brain to a map. Scientists in this field seek to gain knowledge of the physical processes that underlies human sensation, attention awareness and cognition. (Brandmapping, 2007) It is no longer a dream for us to understand people’s mind. However, the potential unethical abuses of this technology should be predicted and minimised in long term.
Firstly, we should benefit this amazing technology within a limited extent. Since this technology requires large amount of capital and operating costs, it can be utilized in certain field, such as medical intervention. It has proven that the work could have applications in the study of autism, disorders of thought such as Pick’s disease (National Science Foundation, 2008). Furthermore, brain mapping also could be used in detecting the truth from suspected criminal and thus it enhances the law enforcement. As a result, brain mapping is always applicable if it is using in the right field.
Secondly, the result from brain mapping should not be unveiled or conducted to public in case of privacy. Every brain mapping processes should be undergone under a primary condition and agreement. The data obtained will only be the references for some applications or research but not abusing it. Besides that, the data retrieved has to be stored safely since it is treated as a form of privacy. In summary, processing the data resulted from brain mapping has to be specific and expertise in order to protect the privacy of everyone, as it is stated in law.
Lastly, brain mapping technology should not be introduced to the public regarding of its value. Even though everyone posses the potential as a terrorist in this community today, there is no necessary for everyone to undergo this treatment, especially children. In fact, everyone has their own talents and abilities to be untapped in their life journey. Therefore, it is anti-natural for them to use brain scanning for educational proposes instead of exploring by their own. Brain mapping will only pose potential of privacy’s intrusion. In summary, brain mapping will bring more negative effects than the positive one to the public.
In conclusion, brain mapping can really benefit people by increasing the efficiency of researching in many fields but only with a positive aim. I believe that the power of brain mapping is unpredictable and thus we should not abuse it in the future whenever it is not ready justified as a stable technology.

Is That Global Warming Occuring?
Polar ice caps melting, economic consequences, increased intensity of drought and temperature of ocean and spread of the diseases are the top 5 deadliest effects of global warming in the latest century. (Simmons, 2007)These phenomena are caused by the emission of greenhouse gases from people and it should be solved as soon as possible. In the future perspective, some people have come to a conclusion that mitigating climate change is an ethical one. However, the seriousness of global warming is no longer tolerated even with the effort of reducing it by the current technology.
According to the National Snow and Ice Data Center, there are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. If all glaciers melt today, the seas will rise about 230 feet. (Simmons, 2007) Although not all the polar ice caps melt today, the consequences are still serious. It is undeniable that temperature of earth is rising drastically within this few decades. Besides that, increased natural disasters resulted from global warming is also another worrying case since it is unpredictable. Hence, the damages and impacts brought by the global warming are tremendously dreadful.
In fact, Carbon Capture and Storage (CCS) have been introduced by United States since 1980 in order to reduce the greenhouse gases around the atmosphere. In 2005, 60000 tons of carbon dioxide has been injected into aquifer of salty water 700 meters beneath the surface. (Quirin, 2006) However, scientists estimated that 8.4 billion tons of carbon dioxide have been releasing every year. (CDIAC, 2008) It is obvious that technology cannot totally eliminate the greenhouse gases indeed. From engineering perspective, climate change can only be reduced by decreasing the amount of gas before emission but not capturing the gas back to the ground after releasing.
Besides that, to overcome the global warming, many climate change mitigation programs have been proposed. For example, reducing use of vehicle has been promoted in Singapore. Public transportation is more likely encouraged for people instead of driving their own cars. As a result, the responsibility of mitigating climate change is no longer bore by the rich but also the poor. People should face the climate change together but not weighing the benefits and costs when the problem is on the edge. Hence, global warming should not be prolonged.
In summary, global warming is indeed occurring in earth since technology is no longer the best way to mitigate climate change anymore. It is always the high time for everyone to solve it regardless of values. If the earth is suffering too much, human cannot bear the loss in future indeed.

Summary 2
Popularly, scientists and engineers have been described as two different jobs in young. Scientists investigate, invent, and discover while engineers make, apply, and construct. However, in the reality, scientists always work with engineers. They work together to explore new information in the physical and biological world. Firstly, scientists are always need specific instrument to make experiments over their researching. Thus, they need the latest mathematical and computing methods and insert them into their systems for better understanding. New methods for studying the brain should assist the study of memory, learning, emotions, and thought. In exploring the universe, engineers also play an important role in future. In fact, scientists do not know what most of the universe is made of initially. They are the engineers who have continuously worked on to search a better answer for the questions. In addition, the investigation of universe is further improved by the invention of new and modified telescopes, both on the ground and in space. As Einstein said, finding out may require new tools to unlock the secrets of matter and energy. Engineers will be able to devise economical, but more powerful tools to assist scientists to explore realms beyond the reach of current technology. In the future perspective, the foundation of quantum mechanics will be another field for engineers and scientists to cooperate, in order to explore new insights and knowledge. In summary, the greatest challenges will be faced by engineers, scientists, and society itself. Engineering’s success in finding answers to nature’s secrets will not only advance the understanding of life and the universe, but also provide engineers a better working enthusiasm in their life.

Zero Waste - Writing Task Question 2
What is zero waste? I believe many people have never search these two words through Google on the internet though. Basically, zero waste is meant by a concept to extend the current recycling to form a circular system which the waste can be reused and minimized. In order to solve waste disposal problems, zero waste has been largely implemented in many Western countries such as US and Canada. However, even though the 3R program (Reduce, Reuse and Recycle) has been introduced in my country, I always agree that zero waste is a must for every country to adopt as 3R is only a part of it.
In fact, zero waste has the strategy to turn disposal into the raw material for other products. In other words, zero waste can turn useless outputs into useful inputs. For example, a Coca Cola glass bottle is primarily produced with a potential to be recycled and reused in the factory. When the bottle is recycled and washed, the only wastage will be the wash-water and energy loss will be minimized. Apparently, the idea is different from 3R. It is not only reusing the waste but it also relates to the redesign of the goods which has potential of reuse. As a result, the outputs will not be disposed entirely.
Besides that, zero waste has created good job opportunity for the people in these struggling communities. This has been a key factor in New Zealand, where zero waste is regarded more as a driver of local economic development than a matter of environmental conscience. (Collins, 2002) For instance, people just have to recollect and classify the wastage they created, and resell them to certain recollection centre. In addition, it always creates benefits even it is little. Who does not want the profit? Zero waste can really help the poor and grow the country, indirectly.
In summary, zero waste proposes a new idea of producing recyclable goods and increases the economic growth in a country. Although zero waste cannot be strictly zero, it always approximate to zero if the idea is well applied. As a future engineer, I strongly think that zero waste should be adopted in my country as soon as possible.

In 1995, I started my journey of learning English. Since my mother language is Chinese, I always met difficulties in writing a complete sentence. Even until now I will still make some grammatical mistakes in my writing. Most often, I could not translate a sentence well from my mind with English.
As an engineering student, writing an academic essay is unavoidable. In fact, engineering students have a lot of reports and assignments to deal with. Some of them maybe spend a student 2 days to complete and recheck. For myself, I met some difficulties in writing MLE1101 assignments. I was not able to write my assignments and lab reports with the sentences coherence with each other especially when the format is not provided. In addition, I always have grammatical mistakes in my essay. It seemed like a destiny, unavoidably. Besides that, due to lack of vocabulary, I have always stuck over my mind since I could not express my thought with words in my writing.
In order to improve my weakness in writing, I will try to use more transition signal to make the whole essays more coherent. Before I start writing, I will outline all the main points and distribute them to every paragraph. All the thesis statements have to be stated clearly with solid evidence. Furthermore, I will pay attention to my spelling and punctuation as well as the grammar. After finishing the first draft, it is time for me to proofread and edit the essay. I will also let my friends to comment and reedit the essay in order to make it more perfect in accuracy.
In summary, writing is just like a lifelong learning journey. Opportunity is always waiting for those who want to improve. So, I will enhance my writing skills with great enthusiasm, indeed.

Writing Assignment 2
Can you imagine that 600 million cars floating on the air around the earth every year? It has the same weight as the amount of carbon dioxide emitted on earth every year. It is unbelievable. Referring to the data collected in 2007 by Carbon Dioxide Information Analysis Centre (CDIAC) for United Nations, 8.4 billion metric tons of carbon dioxide gases have been emitted through the burning of fossil fuels annually and it is believed to be increasing continuously in the following years. Regarding to this issue, Stephens (2006) concluded that carbon capture and storage (CCS) is a feasible way to reduce pollution caused by coal-fired power generation in the world today. However, I do not agree with her that CCS is applicable to all countries, especially developing countries.
CCS is mainly about capturing carbon dioxide in a large quantity from power plants and storing it in order not to release it to the air. Basically, the technology comprises three parts: capture, transport and storage. However, these three parts require a large amount of capital and investments to operate separately and it certainly will become a great economic burden to a country, especially those in developing countries. “A new power plant costs 1.5 billion dollars to build, it will cost an extra 700,000 dollars to fit the capture equipment on the first experimental plants,” said Professor Haszeldine (Hilary & Ilana, 2008). The expenses of operating a CCS power plant can be increased by using chemical absorption and energy. Furthermore, transferring the gas by container or pipe to storage will add to a country’s financial burden as well. Rather than spending hundreds of billions of dollars to pump tons of gases into the ground by using current CCS technology, why not research a better power generation method by using renewable energy?
Everything in this world has pros and cons; so does this technology. CCS gives rise to other environmental problems other than global warming. In fact, the most serious risk faced is the potential leakage of the pumped gas back into the atmosphere. Carbon dioxide may be emitted to the air through abandoned wells and underground cracks or even released by natural disasters such as earthquakes or volcanoes. In 1986, 1700 people died after a disaster where 1.2 million tonnes of carbon dioxide were released from the lake into the ground in Cameroon (Alister, 2006). The gases can cause asphyxia as carbon dioxide is heavier than oxygen in the air. Besides that, storing tons of carbon dioxide underground and in oceans may increase the acidification of soil and sea water, and as a result, the equilibrium of the ecosystem in soil and water will be affected.
In addition, even though the concept of CCS is gradually spread among all the countries, it has not been demonstrated on a large scale power plant today. The main reason is the overall operating costs are significantly high and thus developing countries are not able to support it in long term. Even if the United States government has planned the first large scale CCS project--FutureGen--it does not have a regulatory framework and clear incentives to invest (Stephens, 2006). The public seem likely to reject the idea of CCS based on the high costs instead of the critical leakage since the technology is not yet popular.
In conclusion, CCS can bring negative impact on people. It requires the cooperation and rapport between developing and developed countries in order to maximize its efficiency in the future. Also, it may not be realistic to invest a large amount of capital on CSS since there are a lot of other social problems to deal with, especially in a developing country. Thus, I believe that CCS is not the best way to solve the problem of global warming today.

Reflection
Time pass in a blink of an eye. Two months have over and mid-term tests are coming soon. Well, I am glad to become one of the members in the family of E02. I have made a lot of new friends from different nations here, and my Singaporean tutor as well. For the first two months, I have tried to improve my language in many ways. Firstly, I learnt how to quote and cite people’s words in a correct style. Secondly, I have been taught to organize my essay by step, from outlining to conclusion, systematically. Thirdly, I have also started leaving comments to my friends in order to improve my error identification skill, as well as my friends’ writing skills. Our relationships are connected with our own efforts. That is a win-win situation indeed. For the next term, I would like to learn more about casual speaking skill in real life communication/conversation. For example, I would like to practice more about the proper way of using words like “Bravo”, “Well” etc. Besides that, I think that presentation is also an important part in our studies. I suggest that we can make more practices about giving clear speeches in order to communicate well with people. Lastly, accurate vocabulary is also a must for all of us to master. I hope that we can learn more vocabulary so that we can apply them in our future essays. I convey my best wishes to all of you who always try to improve yourselves. Thank you. English is special.

In the 21th centuries, nuclear reactors have been built for research or power. However, they have possessed the potential of providing the raw material for nuclear booming. With the wide publication of instructions for building explosive devices, terrorism can become a serious threat to every nations today. Normally, terrorists have to obtain fissile material — plutonium or highly enriched uranium capable of rapid nuclear fission. These highly enriched bomb-grade uranium and plutonium which are ideal fuels for nuclear explosives can be found on any nuclear reactors. In fact, engineering play the roles of finding all the dangerous nuclear material in the world and tracking it in order to avoid abusing by terrorists. So there are several steps to protect the materials. Firstly, engineers have to secure those nuclear materials. Secondly, they have to know how to detect them within a distance. Thirdly, engineers learn how to design a potential device safely. Emergency backup, cleanup, and public communication after a nuclear explosion are also especially important. The most importantly, engineers must also have to determine who did it. Besides, for another case like “dirty bombs” which might cause health disturbance, deaths, contamination and economic havoc, engineering changes from monitoring to cleanup, of both people and places. In case, potential sources of radioactive material are scattered about the globe, preventing access is very hard. To certify that a country using nuclear power just for generating energy is not easy. To oppose this problem, engineers have developed a passive device near a reactor which could transmit real-time data on the reactor’s contents, to detect any lost of plutonium. Consequently, preventing their transportation to a place of use has gradually become an significant issue. Individual inspection of each container would be costly and very disruptive as many goods are legitimately imported into the country within large shipping containers. Many ways of detecting nuclear materials hidden in such containers have been used, but most of them bring negative results. In conclusion, engineers have to face these new possible challenges with the time. By the good understanding of nature’s nuclear secrets provided by physics, engineering are to be encouraged to challenge themselves in the future.

Everyone does make mistakes, no matter big or small. As well as we born to this world, we are going to make mistakes in destiny. As a normal insane, I did make mistakes and I will not deny that I will continue making mistakes throughout my life eventually. However, to become a better "player" in this competitive world, I have spent plenty of time and effort to enhance my language. And one of my problems I faced currently is the grammar mistake, especially the preposition in sentences. In definition, a preposition is a word governing, and usually coming in front of, a noun or pronoun and expressing a relation to another word or element. ( English Club ) A preposition must be followed by a "noun" but not a verb. The "noun" can be including noun (cat, eye), proper noun (Mr.Yan, Malaysia), pronoun (I, you, we), noun group (my first friend) and gerund (jogging) as well. For an example, I go to school by bus. The "by" in the sentence is actually a preposition and it is followed by noun (bus). Sometimes, using wrong different preposition can give different messages. For instance, "The girl walks into the house." and "The girl walks to the house." show the different meaning indeed. Referring to my last assignment, I can find out my preposition's mistakes are based on the preposition of place and time. Instead of using "on 18th of August", I always made the mistakes by using "at 18th of August". Now I only realized that these are the areas i should pay attention to. In a nutshell, I believe practice makes perfect. In order to minimize my grammatical mistakes, I would not hesitate to make more practice, orally and manually.

No more songs and music. No more glamorous designs of buildings and products. No more literature and history in the world. How can we survive in this kind of "cold" world? That is impossible. Nowadays, people have been much involved in the challenges of improving the quality of life with advanced technology. Science, Technology, Engineering and Math (STEM) education are likely to be encouraged to the youth but not language arts anymore. These kinds of notions can really cause a lot of drawbacks in future. Undoubtedly, people today are seemed to be only devoting themselves to the numbers and letters instead of languages. Our mother tongue languages, which include vernacular languages and dialects, are not even applied. Without correcting the grammar mistakes and mispronunciation, the expression of idea by the voice is gradually becoming vague and as a result communication barrier will be occurred. When time goes on, the rate of illiteracy will increase rapidly. Also, development of philology and literature would be affected. Youth today are discouraged from spending too much time on poetry. Poems such as the 300 Tang and Song Chinese poems will no longer be learnt in the world today. Besides, involving too much in STEM will influence the development of art to a certain extent. When people bury themselves into the books, they cannot value the beauty of art and they lost the capability of judging works of art. In fact, the mind of creation and innovation is off utmost important in creating the characteristic of a person and it should not be neglected. A Roman author once said, "Art is born of the observation and investigation of nature" (Cicero, n.d.) . Undeniably, art is actually one of the elements in our high-tech life today. In conclusion, That is truth that introducing STEM education to people can better improve our communities and provide people a high-tech environment but to a limited extent. We should not forfeit the right to learn the language art in our stage of life. When we feel stress in chasing the technology, just spare some time to udnerstand the essence of language arts, and unwind ourselves.

According to those two articles, I strongly believe that the variety of the engineering profession is the most important thing in these days and future, too. It has come through several variation throughout the centuries.
In the world today, sustainability technology is the norm so that it can provide a better life for human being. To keep pace with the technology, the engineering profession has to be diverse into various type of specialisation. For an example, mechanical engineering has roughly diverse into mechatronic, aerospace and oil and gas engineering. To meet human need, engineering today is not only involving the matter of manufacture and building but it is also emcompassing the service sector, banking, finance, medicine, computing as well. Undoubtedly, the scope of engineering has been broadened and its variety will be continued in future.
Due to the globalisation challenges , engineering has become highly recommended today due to its vastness of job opportunity. Resources, energy, water, poverty, health problem, high-tech information and environmental disaster will not longer be small issues but they are the prime challenges for all the engineers in the world. Exactly, engineers need to solve their tasks by foresighting the future with creativity.
Nowadays, the engineers can communicate with other engineers worldwide in all forms and share their knowledge conveniently. The engineers will cooperate with others profession to make use of the knowledge. For instances, architecture will need engineers to construct a building to prevent collapse while drug researcher will require engineers to invent a new drug by applying chemistry as well. As a result, the world is more connected to face those challenges together and this give rise to the expansion of engineers' world as well.
In conclusion, the contribution of engineering will not be ignored and it will continue expand into several kinds of specialisation in the future. Due to its flexibility, engineers will be recruited by those large companies in a large demand in the future. So, I agree that the expansion of this profession will really bring benefits to human, to the rich and poor.
