The Evolution Of Microelectronics Information Technology Essay

The Evolution Of Microelectronics Information Technology Essay The technological progress of the past decade has played an important role in the advancement of modern society by continuously supplying better quality goods which are accessible to the mass markets. Innovation has shaped our society as we know it which would otherwise be completely different from simple shopping to the achievements of modern medicine, from the hugely successful entertainment industry to the highly sophisticated education system none of these would have been possible without the solid backbone of modern technology. And technology would not exist if micro-electronics was not the highly developed and researched science it is today. A mere 60 years ago, no one would have been able to predict the impact of emerging technologies on worldwide business and economics few would have fathomed the concept of the Internet or even the remote possibility of wireless mobile telephony. The latest breakthrough in technological research is that of nano-electronics. Even if while writing this, nano-electronics is still a largely uncovered science, the odds are that over the following years it will have the potential to realign society, business and economics. Nano-electronics at the consumer level will touch all aspects of our economy, from wages to employment, purchasing, pricing, capital, exchange rates, currencies, markets, supply and demand. Nano-electronics may well drive economic prosperity or at the least be an enabling factor in productivity and global competitiveness. The Evolution of Micro-electronics. Figure 1: Evolution of Micro-electronics The intensive effort  by professionals in the electronics campus to increase the reliability and performance  of products while reducing their size and cost has led to the results that hardly anyone would have predicted but which we have all come to expect. In-fact many think that electronics made a revolution in human history and shaped our future in a way it would never have been possible. Through the years we saw the evolution of electronic components which decreased in size while performing increasingly complex electronic functions at ever higher speeds. It all began with the development of the transistor. Prior to  the invention of the transistor in 1947, its function in an electronic circuit could be performed only by a vacuum tube. Vacuum tubes were found to have several built-in problems. The main problem with these tubes was that they generated a lot of heat, required a warm-up time from 1 to 2 minutes, and required hefty power supply voltages of 300 volts dc and more. Another problem was that two identical tubes had different output and operational characteristics therefore designers were required to produce circuits that could work with any tube of a particular type. This meant that additional components were often required to tune the circuit to the output characteristics required for the tube used. Figure 2: A typical vacuum-tube chassis The first transistors had no striking advantage in size over the smallest tubes and they were more costly. The largest advantage the transistor had over the best vacuum tubes was that it consumed much less power than a vacuum tube did. Besides they also provided greater reliability and longer life. However, it took years to demonstrate other advantages of the transistor over vacuum tubes. The advent of microelectronic circuits has not, for the most part, changed the nature of the basic functional units: microelectronic devices were still made up of transistors, resistors, capacitors, and similar components. The major difference is that all these elements and their interconnections are now fabricated on a single substrate in a single series of operations. Several key developments were required before the exciting potential of integrated circuits could be realized. The development of microelectronics depended on the invention of techniques for making the various functional units on a crystal of semiconductor materials. In particular, a growing number of functions  have been given over to circuit elements that perform best: transistors. Several kinds of microelectronic transistors have been developed, and for each of them families of associated circuit elements and circuit patterns have evolved. The bipolar transistor was invented in 1948 by John Bardeen, Walter H. Brattain and William Shockley of the Bell Telephone Laboratories. In bipolar transistors charge carriers of both polarities are involved in their operation. They are also known as junction transistors. The NPN and PNP transistors make up the class of devices called junction transistors. A second kind of transistor was actually conceived almost 25 years before the bipolar devices, but its fabrication in quantity did not become practical until the early 1960s. This is the field-effect transistor. The one that is common in microelectronics is the metal-oxide-semiconductor field-effect transistor. The term refers to the three materials employed in its construction and is abbreviated MOSFET. The two basic types of transistor, bipolar and MOSFET, divide microelectronic circuits into two large families. Today the greatest density of circuit elements per- chip can be achieved with the newer MOSFET technology. Today, an individual integrated circuit on a chip can now embrace more electronic elements than most complex pieces of electronic equipment that could be built in 1950. In the first 15 years since the inception of integrated circuits, the number of transistors that could be placed on a single chip has doubled every year. The 1980 state of the art circuit is about 70K density per chip. The first generations of the commercially produced microelectronic devices are now referred to as small-scale integrated circuits (SSI). They included a few gates. The circuitry defining a logic array had to be provided by external conductors. Devices with more than about 10 gates on a chip but fewer than about 200 are medium-scale integrated circuits (MSI). The upper boundary of medium-scale integrated circuits technology is marked  by chips that contain a complete arithmetic and logic unit (ALU). This unit accepts two operands as inputs and can perform any one of a dozen or so operations on them. The operations include addition, subtraction, comparison, logical and and or and shifting one bit to the left or right. A large-scale integrated circuit (LSI) contains tens of thousands of elements, yet each element is so small that the complete circuit is typically less than a quarter of an inch on a side. Integrated circuits are evolving from large-scale to very-large-scale (VLSI) and wafer-scale integration (WSI). Since the transistor was invented over 50 years ago, the trend in electronics has been to create smaller and smaller products using fewer chips of greater complexity and smaller feature sizes. The development of integrated circuits and storage devices has continued to progress at an exponential rate; at present it takes two or three years for each successive halving of component size. Nanoelectronics refer to the use of nanotechnology on electronic components, especially transistors. Although the term nanotechnology is generally defined as utilizing technology less than 100  nm in size, nanoelectronics often refer to transistor devices that are so small that interactions and quantum mechanical properties need to be studied extensively. As a result, present transistors fall under this category, even though these devices are manufactured under 65  nm or 45  nm technology. Nanoelectronics are sometimes considered as disruptive technology because present candidates are significantl y different from traditional transistors. Some of these candidates include: hybrid molecular/semiconductor electronics, one dimensional nanotubes/nanowires, or advanced molecular electronics. Although all of these hold promise for the future, they are still under development and will most likely not be used for manufacturing any time soon. Economical and Social Impact of Micro-Electronics and Nano-Electronics. Fears of massive unemployment have greeted technological changes ever since the Industrial Revolution. Far from destroying jobs, however, rapid technological advance generally has created many new important opportunities. In the quarter-century, the industrial economics were flooded with new technologies while at the same time the amount of unemployed people has drastically been lowered. Lately with the help of new findings in the area of microelectronics and nanoelectronics they will have a fundamental impact on both the numbers and types of jobs in the industrial worlds in the following years. The microelectronic revolution already affected employment in enterprises ranging from steelworks to any other company and will continue to affect every aspect of work. Although microelectronic and nanoelectronic controls will not sweep through the industrial world overnight, most experts expect them to be firmly established in production processes. Set against these concerns, however, its a fact that nanoelectronic technologies will increase productivity over a broad range of industrial enterprises. In theory this should lead to enhanced economic growth, which in turn will translate into new roles. Put crudely, the extra production made possible by technological changes coincided with rising wealth and increased demand for manufactured goods and services, a combination that leads to high rates of economic growth and near-full employment. As is well known, combination of technological changes and economic pressures led to a sharp reduction in the worlds agricultural work force over the past half-century. In every major industrial country the agricultural labor force now represents less than 30 per cent of the working population. While the number of agricultural workers has decreased, however, output has risen substantially in general due to manufacturing firms which thus have replaced the workforce needed. At the same time, output, while fluctuating in tune with recessions, has increased. The phenomenon of jobless growth (growing in manufacturing but decreasing or maintaining the same level of employees) has now become established in the goods producing companies, this because mainly through technological change. Underlying this trend is the fact that investment in new production technologies has sought largely to streamline production processes rather than to expand output at a time demand is low and there is a high average wage rate. While these jobs and investment patterns have been developing, employment in the tertiary sector of finance, insurance and government services has been expanding rapidly. It is important to note that it is the productivity increases in the manufacturing industries that have themselves created the economic growth that in turn led to the increased demand for the services of the tertiary sector. This transition from agriculture to industry, and more recently to tertiary sector employment, has not been smooth or even. First, it is clear that microelectronic technologies will create jobs in those industries which manufacture electronic products. There are billions of money which are being lavished on mobile phones, electronic gadgets, computers and other microelectronic products which have spawned a whole industry that did not even exist a decade ago. It was found that about 10 million people are now employed in the electronics industry in the United States only. Through research and technological advancements micro-processors are much more efficient and cost effective that these are being used in almost everything. Micro-processors nowadays can be found in washing machines or incredibly enough also in toys, where years ago one would need to be very wealthy to have a micro-processor working and the phenomenal speeds which they work now. The use of microprocessors in manufacturing industries has essentially intensified the jobless growth that has been taking place in industrial countries in recent years. One should also note that the use of computers and other intelligent machines will lead to increased employment in some areas such as the growing industry of e-business. Today almost every person of the world bought something from the Internet, may it be clothes, electronic products, or any other thing. This industry nowadays is producing so much money that is very difficult to quantify. Computer programming, for example, is a labor-intensive activity that is a likely source of many thousands of new jobs. Demand for programmers is already outstripping supply, and some analysts have even suggested that this shortage could constrain growth in the use of computers in the coming years. But in most other areas of the tertiary sector, microelectronics is likely to lead to slower rates of employment growth or even to job losses. In areas such as insurance and banking, which arc labor intensive occupations that rely primarily on printed paper for their transactions, the application of electronic technology could have a major impact. Nowadays everything in the office is automated . The introduction of word processors, computers, and emails is also another aspect which has affected the economy both from a positive side and from the negative side. In todays offices only a few clerks are needed for what used to be a 50 person job in the 1960s like for example, a word processing task which is done using a computer and which has indeed resulted in unemployment., The positive side is that companies are much more efficient and communication is much more reliable. A simple example is a clerk who is employed with a company which deals with shipping of goods. Nowadays with the help of VPNs (virtual private networks) the clerk connects to his companys server through the internet and can work easily from home. This would alleviate electricity costs for the company as the employee is working from home, while the employee is comfortable working from home. Another simple example how reliable communication has advanced through technological research is by the use of emails. To day one sends an email to any recipient with some simple keystrokes. In turn the recipient receives this email in relatively a few minutes, and if there is a failure the system automatically notifies the sender that a communication has failed and he needs to resend it again. When postal mail was used it was a common thing that mail was lost and neither the sender nor the receiver would know where the letter is and if it has been delivered. The corporate computing environment has witnessed dramatic changes in the last few years, with a shift from rapid expansion of IT infrastructure in support of growing business needs, to carefully managing existing assets and investing in new strategic technologies that provide specific competitive advantages. Information technology managers today are challenged with providing more services to more users, meeting ever-increasing performance expectations, storing and managing exponentially increasing amounts of data, better protecting the network, a nd ensuring system stability-all with limited possibility to expand data centres because of shrinking budgets The advance in microelectronics and nanoelectronics affects not only the number of jobs in industrial countries, but also the type of jobs which will be available. The early use of robots on assembly lines has largely been dangerous and dirty. But as automation extends into design shops and machine rooms, highly skilled occupations were affected. And, at the other end of the sale, the use of computers and storage area networks have eliminated many filing and routine clerical jobs. Microelectronics thus has the potential, to decrease skill requirements in some jobs and increase them in others. Another example where micro-electronics has succeeded is in the area of robotization. The main purpose of robotization is certainly to improve the productivity of manufacturing processes and the qua1ity of products, which help increase competitiveness of produced goods in the market and bring in gains for the companies. From a broader view point, the increase in process productivity may accelerate growth of these industries and then contribute to the growth of the national economy. The preceding discussion indicates that robotization gives rise to reduction in employment in manufacturing processes, which will be at least partly covered by expansion of the market in the long run. It is obvious that seriousness of the employment impact will be greatly eased by the latter effects. Therefore we should estimate how much these effects will be, and if possible in what time spans these effects will emerge. However, it should be noticed that the compensation is only to a certain degree even if it takes over the first type impact in number. The job pattern in a factory or a company will change and transfer of labour force from the jobs for which robots are introduced to those created by market expansion is unavoidable. Another type of economic impact of robotization is as described before impact on the international market. Expansion of exports or at least the reduction of imports of manufacturing goods due to increase in their competitiveness in the international market gives positive impacts on the national economy, but in many cases with the sacrifice of worsening trade balance of partner countries. It means that the competition in the international market is likely to be a zero sum or a1most a zero sum game at least in the short run. All developed countries are certain1y members of the game, new1y industrialized countries or emerging countries will be more sensitive to changes in market competitiveness of member countries. Though the microelectronic revolution already impacted most of the countries in the world, nanoelectronics is likely to have a major impact on the numbers and types of jobs available in the industrial world over the next few decades, every expert who has studied the subject has reached the same conclusion: More jobs will be lost in those countries that do not pursue the technology vigorously than in those that do: Because nanoelectronics will enhance productivity so greatly, the industries that move swiftly to adopt the technology will have a competitive advantage in international markets. As the global economy continues to be transformed by new technology, there will always be need for talent, intellectual property, capital and technical expertise. We see many of these factors responsible for shaping how nations today compete, interact and trade. Technical innovations will increasingly shape economies and market robustness. Technology will continue to drive global and domestic GDP. Competition will be fueled increasingly by fast breaking innovations in technology. Today this is obvious as rapid technological changes in telecommunications, life sciences, and the Internet demonstrates the emergence of entirely new economic and business realities. If the proliferation of todays technologies to form new business models is any indication of the speed and power of change in the economy, future nano-technologies will make for an even more dramatic shift. Rates of progress in microelectronics suggest that in about a decade 80% of the people in the world will possess a notebook-size computer with the capacity of a large computer of today. The future increase in capacity and decrease in cost of microelectronic devices has not only given rise to compact and powerful hardware but also bring qualitative changes in the way human beings and computers interact. Computing and storage capacity are many times that of past microcomputers: tens of millions of basic operations per second manipulate the equivalent of several thousand printed pages of information. The personal computer can be regarded as the newest example of human mediums of communication. Various means of storing, retrieving and manipulating information have been in existence since human beings began to talk. Although digital computers were originally designed to do arithmetic operations, their ability to simulate the details of any descriptive model means that the computer, viewed as a medium, can simulate any other medium if the methods of simulation are sufficiently well described With the technological advance in nanoelectronics multi-core processors represent a major evolution in computing technology. This important development is coming at a time when businesses and consumers are beginning to require the benefits offered by these processors due to the exponential growth of digital data and the globalization of the Internet. Multi-core processors will eventually become the primary computing model because they offer performance and productivity benefits beyond the capabilities of todays single-core processors. Multi-core processors will also play a central role in driving important advancements in PC security and virtualization technologies that are being developed to provide greater protection, resource utilization, and value for the commercial computing market. One particularly frustrating process is compiling software after the code has been written. Compiling is notorious for overloading computer processor capacity and causing, in many cases, lengthy development cycles. During these periods, software engineers are at the mercy of their computer resources. In many cases, the speed at which software code is being compiled results in greater productivity for the programmer. Overall, that translates into a more efficient software development cycle. Consumers, too, will have access to greater performance than ever before, which will significantly expand the utility of their home PCs and digital media computing systems. Multi-core processors will also have the benefit of offering performance without having to increase power requirements, which will translate into greater performance per watt. Placing two or more powerful computing cores on a single processor opens up a world of important new possibilities. The next generation of software applications will likely be developed using multi-core processors because of the performance and efficiency they can deliver compared to single core processors. Whether these applications help professional animation companies produce more realistic movies faster for less money, or create breakthrough ways to make a PC more natural and intuitive, the widespread availability of hardware using multi-core processor technology will forever change the computing universe. Computer processor design has evolved at a constant pace for the last 20 years. The proliferation of computers into the mass market and the tasks we ask of them continue to push the need for more powerful processors. The market requirement for higher performing processors is linked to the demand for more sophisticated software applications. E-mail, for instance, which is now used globally, was only a limited and expensive technology 10 years ago. Today, software applications span everything from helping large corporations better manage and protect their business-critical data and networks to allowing PCs in the home to edit home videos, manipulate digital photographs, and burn downloaded music to CDs. Tomorrow, software applications might create real-world simulations that are so vivid it will be difficult for people to know if they are looking at a computer monitor or out the window; however, advancements like this will only come with significant performance increases nd inexpensive computer technologies. Multi-core processors have the potential to run applications more efficiently than single-core processors-giving users the ability to keep working even while running the most processor intensive tasks in the background, like searching a database, rendering a 3D image, ripping and burning music files to a CD, or downloading videos off the Web. For years, independent software vendors delivered imaginative and robust solutions to solve real-world problems, benefiting both businesses and general consumers. Businesses rely on constantly improving software for automating exceedingly complex processes, including those dealing with e-commerce and information management. Consumers are doing more complex tasks on their PCs, including manipulating digital photographs and media, and running cutting-edge games. The sheer number of new applications, and the exciting functionality they provide, is a credit to software engineers. However, in their quest to design more sophisticated applications, while at the same time making them easier to use and more cost-effective, these professionals are regularly pushing the limits of current processor capacity. Multi-core processors will solve many of the challenges currently facing software designers by delivering significant performance increases at a time when they need it most. With increasing competition and market demands, engineers need to provide more functionality into their designs in less time. Whether enhancing and updating large, enterprise applications or developing the next generation PC game, software developers are acutely aware of the computational requirements during each phase of creation. In additional to what we have read already, nano-electronics affects also the academic part in our society, the knowledge and competencies required for working in the field of future nanoelectronics which are evolvingvery fast. At both ends (material/devices and circuits/systems) there is the need to renew and redefine the content of the knowledge portfolio that colleges provide to students or to company employees for continuous education. Micro-electronics and nano-electronics not only allow us to work comfortably or to enjoy high quality videos but it helps us to travel as well. The old 1950s vision was to have a car which would drive without the need to touch the steering wheel or that it would have everything which a person would dream about. Nowadays almost every car uses microcontrollers in order to control the car from many different ways like controlling the safety of the car itself. In fact most modern cars have embedded the system of traction control which has a microcontroller which constantly monitors the traction and if there is any fluctuation of loss in traction it will quickly compute the necessary adjustments which are needed to regain traction. Apart from this many modern cars incorporate automatic sensors which in turn are all adjusted, monitored and switch on or off by a controller. It is normal as well to see cars which are switched on simply by pressing a button from the key itself, which is indee d a breakthrough in cars history. Micro-electronics has also effected our lifestyles in so many other ways, making our everyday routine a little more comfortable.. For example, nowadays it is easy to find a complete kitchen system which enables us to set the oven to a pre-defined temperature and cook our meal while we surf the internet or perhaps communicate with our friends through social networks which have become very popular. Other home appliances, like washing machines or electric water heaters, can be set in motion using the internet, from practically any location. Micro-electronics has also contributed effectively in administering the use of electricity more efficiently. Todays appliances incorporate sensors and controllers which continuously monitor energy consumption and if there is anything which is not being used in-turn they will turn it off in order to consume less power. The above examples are proof that research in the area of micro-electronics and nano-electronics has contributed hugely to change our society in many positive ways. Teleworking is slowly becoming a reality for many people, enabling them to commute from their own homes, eliminating the need to travel to work, thus giving parents more flexibility. Communication has been made easier because of better telephony as well as more advanced mobile technologies. Scientists are able to carry out research using extremely sophisticated and intelligent machines which was only possible with advancement in the micro-electronics and nano-electronics fields. Conclusion The debate about the social implications of microelectronics and nanoelectronics is ongoing. The past has shown us how the switch from old technologies to micro-electronics has affected all aspects of life, from the standards of living to employment, from a more organized social environment to the manifestation of socio-cultural problems such as modern depression, alienation, helplessness and growing resistance against changes. Mankind is now on the brink of another major change that of changing over from using microelectronics to the newer technology of nanoelectronics and this implies another impact on everything we know. This time, influences on employment will be profound but difficult to predict, because different sectors are affected differently. Nanoelectronics will have a significant impact on the semiconductor industry. All electronics related items like memory devices, storage devices, display devices, and communication devices will be swept away by the nanoelectronics wave. From transistors to the computers they fit in, every single device will undergo transformation. Nano-scale devices will enable the creation of a new world of innovative products, such as biosensors, molecular memory, spin based electronic products, and flexible and light-weight photovoltaic cells. The change is inevitable. The future is nano-electronics.

Scarlet Letter :: essays research papers

Nathaniel Hawthorne was a truly outstanding author. His detailed descriptions and imagery will surely keep people interested in reading The Scarlet Letter for years to come. In writing this book he used themes evident throughout the entirety of the novel. These themes are illustrated in what happens to the characters and how they react. By examining how these themes affect the main characters, Hester, Dimmesdale, and Chillingworth, one can obtain a better understanding of what Hawthorne was trying to impress upon his readers.   Ã‚  Ã‚  Ã‚  Ã‚  The first theme expressed in The Scarlet Letter is that even well meaning deceptions and secrets can lead to destruction. Dimmesdale is a prime example of this; he meant well by concealing his secret relationship with Hester, however, keeping it bound up was deteriorating his health. Over the course of the book this fact is made to stand out by Dimmesdale’s changing appearance. Over the course of the novel Dimmesdale becomes more pale, and emaciated. Hester prevents herself from suffer the same fate. She is open about her sin but stays loyal to her lover by not telling who is the father of Pearl. Hester matures in the book; becomes a stronger character.   Ã‚  Ã‚  Ã‚  Ã‚  The fact that revenge destroys both the victim and the seeker is another theme presented in the Scarlet Letter. Dimmesdale is the victim of Chillingworth’s revenge upon Hester and whoever her lover happened to be. Dimmesdale, beside his self-inflicted harm was also not helped by the fact Chillingworth enjoyed watching him waste away. However, Chillingworth is also subject to this destiny as evidence by his change in the novel. Chillingworth was considered wise and aged in the beginning of the novel, although, later he is seen as being dusky and evil.   Ã‚  Ã‚  Ã‚  Ã‚  Lastly Nathaniel Hawthorne brings out that we absolutely must accept responsibility for our actions or suffer the consequences come with them. Hester is the prime example for this here because she was smart and freed herself of this great weight quickly so that it wouldn’t drag her down. This theme was not as applicable to Dimmesdale, however, who decided to hide his wrongful actions and was bearing this secret upon his heart and mind at all times.

Did the Church Help or Hinder the Progress of Medicine in the Middle Ages?Did the Church Help or Hinder the Progress of Medicine in the Middle Ages?

Did the church help or hinder the progress of medicine in the middle Ages? In this essay I will be looking at the different aspects of medicine in the Middle Ages and accessing how the church helped or hindered their development. As there was a lot of unrest at the start of the middle Ages the church is important because it preserved a lot of things. It also provided a way of life, so it was very influential. The Church did not encourage the development of new medical ideas, it was not in their interest.When Roger Bacon (a thirteenth century priest) he suggested that a new approach to medicine was needed he said that doctors should their own original research instead of learning from the books of ancient writers such as Galen. Church leaders put him in prison for heresy there is an engraving showing him smuggling his work out of prison. The church banned dissection for a time, however from 1492 the pope allowed dissection as long as the body was that of a criminal. The first medical school was set up in Salerno in 900 AD by the church.By the Montpellier in France was the most famous but there was a number of others at these school students listened to lectures where the teachers read out passages from the work of Galen and other ancient writers. The church did provide some training for doctors as they gave money to the universities. Without this money, the universities would not have been able to survive. Students would be able to listen to a lecturer talk about the work of Galen. In France, the church allowed the students to dissect one body a year for research.However, the doctor would only watch as the dissection was done. The church taught that Galen’s ideas were correct so that idea that dissection could be used to check his ideas did not cross anyone’s mind. Dissection was used to illustrate Galen’s ideas about the body. The church had taught different types of cure for illness. Thousands of people flocked to Canterbury because it was said that Becket’s blood could cure blindness, leprosy and deafness. The church taught that prayer could cure illness. Holy oil and water were used to treat people.Many people carried parchments from the bible to warn off disease. The church paid for hospitals to be built. It taught that it was your Christian duty to look after the sick. In the 13th century over 160 hospitals were built. The monasteries had libraries. However, only monks had access to the books. The church could ban books that it did not like. The monks would teach children to read. Some religious houses had very strict rules because the most seriously ill people would need a lot of looking after. No lepers or lunatics, or person having the falling sickness or contagious disease. No pregnant women, or suckling infants, no intolerable persons even if they are infirm should be allowed in the house. † From the rules of a religious hospital in 1219. A cure for toothache in the 1300’s recommended by John of Gaddesden a leading English doctor â€Å"Write these words on the jaw of the patient. â€Å"In the name of the Father, Son and Holy Ghost, Amen. † The pain will then cease at once. Monasteries were used to care for the sick.Many had running water and provided fresh food and rest to the poorest people. â€Å"Care for the sick stands before you all. You must help them as Christ would. Let it be the chief concern of the Abbot that the care of the sick be his main concern. â€Å"From the rules of Benedictine monasteries. The monks were not trained doctors and were more likely to pray for you than give you effective treatment. The church had also taught that kings had a link to God that gave them the power to heal. Alms-houses gave shelter to the poor, the elderly, widows, young children and pregnant women.They were run by priests but no real medical help was given. Many monasteries had herb gardens. The monks used their knowledge of medicine from the books in their lib raries to make herbal remedies. However, there is little evidence of them being able to make new cures for disease. Because of the church, doctors had to have a licence to practice medicine. This is the beginning of qualifications for doctors. After the 13th century it was illegal for a person to call themselves a doctor without having formal training.

Honey And Mumford Learning Style Education Essay

It is normally believed that most people have a penchant with respects to interacting with, taking in and treating information to let them to larn ( Smith, 2003 ) . Different people adopt different acquisition manners where an optimal manner allows the person to larn best. The construct of individualized acquisition manners has gained a great trade of popularity in recent old ages of all time since the thought was proposed in the seventiess. To day of the month, there has been a monolithic copiousness of trials that can be performed to measure a individual ‘s acquisition manner ( Sprenger, 2003 ) . The undertaking is divided into two parts: Part A: To place and analyse my learning manner penchants through assorted questionnaires ; the VARK trial, Honey and Mumford acquisition manner, Myer Briggs Type Indicator ( MBTI ) and Belbin ‘s squad stock list. Prem and Phil stated that â€Å" Learning affects public presentation because all public presentation can be improved through acquisition. † ( Prem & A ; Phil, 2008 ) . Therefore, this allows me to derive an apprehension of who I am as a scholar and how this cognition may impact my public presentations, both separately or within a squad environment. Part B: To discourse my personality type and how my learning manner may impact my calling picks. However, it is deserving observing that although â€Å" personality is a possible subscriber to acquisition, it is hard to specify † ( Davies, 2008 ) . Sigmund Freud used the analogy of an iceberg to explicate the complexness of human personality by proposing that most of the personality is hidden out of sight under H2O ( Freud, 2003 ) . Hence, placing one ‘s personality is non an easy undertaking, and trials should merely be used as a ‘starting point ‘ instead than as a agency to do definite opinions ( Bayne, 1997 ) . However, my consequences will give a general thought of a calling field that most closely fit my personality and strengths.Part 1: Who I am as a scholar?1.1 VARK TestThe VARK trial is one of the most normally used theoretical accounts to assist place an person ‘s penchant for having and analyzing information with respects to larning. It can as sist people to develop extra acquisition schemes. There are four manners for people to utilize, such as ocular, aural, read/write and kinesthetic ( VARK, 2009 ) . It is a model to measure a individual ‘s learning manner. The consequences of the VARK trial ( Appendix A ) suggest that my strengths in a acquisition context remainder on my aural accomplishments. I have a strong penchant for aural based acquisition since I like to listen to others during treatment to derive a different position which allows me to understand more of the subject being discussed. My group mate agrees with this by stating †Although Yin Sung is usually quiet during group activities, she is an active hearer of other people ‘s positions and attentions about other people ‘s ideas, † ( Vicky, 2010 ) . Another portion of the trial consequences that I peculiarly agree with is that my written/reading accomplishments rather weak and is n't my preferable method of larning. Having merely late moved to analyze in the UK, English is non my first linguistic communication which could explicate why this type of acquisition is non one of my chief strengths, although my proficiency is bettering a batch. Since, the western educational system places a batch of accent on reading and authorship, I believe that I will derive a batch of betterment in this acquisition facet as clip goes on with added pattern. However, I am a spot surprised by my low mark on my kinaesthetic accomplishments. I have ever thought that I am person that learns good when given the chance to see something via a ‘hands on attack ‘ . For illustration, I find that I am able to pick up new accomplishments easy ( i.e. badminton ) when I am able to physically seek it out instead than merely reading from a book on how to play.1.2 Honey and Mumford Learning StyleThe Honey and Mumford ‘s ( 1992 ) Learning Style identifies and categorises an person ‘s learning manner. There are four possible manners ; an militant, reflector, theoretician and pragmatist, with a sum of 80 inquiries in the trial ( Honey and Mumford, 1992 ) . Harmonizing to the consequences of the Honey and Mumford larning manner questionnaire ( Appendix B ) I adopt a high reflector outlook. I agree with the bulk of the description of the reflector which I believe to the full depict me. A Reflector is a careful individual who prefers to take a back place in group treatments ( Honey and Mumford, 1992 ) . I like to listen to other people ‘s positions before I come to decisions and take my clip before doing any determinations. Being less self-asserting and be givening to keep back from engagement, I believe that I will work good and larn more expeditiously if placed around an militant, as one would be able to promote me to undertake state of affairss via a more ‘head on ‘ attack. This would heighten my engagement in group activities and treatments. In understanding with my VARK consequences, the Honey and Mumford trial suggests that I am a good hearer which is one of the strengths of a reflector. I to the full agree with this since I have ever been person that likes to listen to everyone in the group thoughtfully. This gives me an chance to derive different positions from different angles before I come to decisions. However, a possible failing that I see in myself by being a reflector is that I spend a long clip when executing set undertakings. For illustration, during my last assignment, it took me in surplus of two months to finish it as I was brooding excessively much on the readying phase. I spent excessively long researching information before I eventually began composing my assignment which is due to my caution with respects to make up one's minding how to compose it. Although I do demo a cautious outlook, I do n't to the full hold with the description that a individual with reflector behavior ne'er likes to take hazards. I on occasion like to step out of my ‘comfort zone ‘ to see things that I have ne'er experienced before to broaden my ain cognition. For illustration, I chose to go forth my place and familiar milieus in Hong Kong to analyze in the UK. I besides like to take up activities and avocations that I have ne'er tried before.1.3 Myers Briggs Type IndicatorThe Myer Briggs type Indicator ( MBTI ) is a questionnaire used to place an person ‘s personality type based on Carl Jung theories. MBTI categorises persons into two maps, such as extroversion or invagination which is the penchant in which an person prefers to direct their energy ( Madeline & A ; Rebecca, 1988 ) . For illustration, one that likes to direct their energy to cover with outer things, state of affairss or other people is deemed to hold a penchant for extrov ersion. Conversely, a individual that likes to cover with thoughts, information, accounts or the ‘inner universe ‘ , so their penchant is invagination. The consequences of the MBTI ( Appendix C ) suggest that I have a dominant introspective map, with a high penchant for introspective detection as demonstrated by my high mark in ISFJ. These consequences show that I like to listen to others and to absorb every bit much information as possible in a peculiar state of affairs, to spread out my cognition and to accomplish a clear apprehension of a subject. These compliment good with my consequences from the Honey and Mumford trial mentioned above. The consequences besides suggest that I am a difficult working person, which I feel describes me good. I like to get down early and guarantee that I perform undertakings to the best of my ability. Sing my academic life, I tend to analyze at least five hours a twenty-four hours. I besides begin my research for assignments long before the deadline. For illustration, although this professional undertaking is due for entry in April 2010, I have been fixing and making the necessary reading since October 2009. The MBTI consequences besides suggest that I have an of import penchant for extrovert feeling, as demonstrated by my high ESFJ mark. I am person that likes to concentrate on edifice harmoniousness in the universe around me and construct positive relationships. Besides, I ever value other people ‘s parts during work or other activities. My old employer said â€Å" Sung Yin is a really personable person that is popular with the clients and staff which creates a really positive ambiance around the topographic point, † ( Mrs Poon, 2008 ) . I will ever seek to carry people to hold with my positions if their sentiments are different to mine. However, I ever need to be careful non to pique those around me while seeking to make so. Briggs Myers stated that although ‘ESFJ ‘s ‘ are â€Å" friendly and sympathetic, they are really diligent and insist that others portion the same positions as them. † ( Myers, 1995 ) .1.4 Belbin Team InventoryThe Belbin Team Inventory is a trial used to estimate penetration into a individual ‘s behavioral inclination in a squad environment ( Furnham, Steele & A ; Pendleton, 1993 ) . The trial allows us the chance to find non merely our single aptitude strengths, but besides gives an consciousness of our place within a squad and how we are expected to lend. It â€Å" scores people based on how strongly they express traits from nine different squad functions. † ( Belbin, 1981 ) . Harmonizing to my Belbin trial consequences ( Appendix D ) , I have a major penchant for a function as a ‘shaper ‘ within a squad. A ‘shaper ‘ contains behavioral traits that correspond to my consequences from the MBTI. For illustration, a ‘shaper ‘ shows a thrust to win and to get the better of obstructions which complements my desire to carry through my aspirations and follow my clear ends. Although I display ‘reflector ‘ features, I besides see myself as a competitory person that thrives on force per unit area and challenges, which forms the footing of the ‘shaper ‘ function. My high school P.E teacher wrote on my school study â€Å" Sung Yin has demonstrated her competitory side during badminton category and has the necessary personality and desire to go a good participant in the athletics in future, † ( Mr. Yeung, 2001 ) . The consequences besides show that I am a ‘monitor judge ‘ proposing that I am an person that likes to measure all options before coming to a decision, which allows me to do accurate opinions. This agrees with my Honey and Mumford trial consequences which say that I am one who likes to derive different positions in treatment before doing determinations ( being a reflector ) . Finally, the trial consequences besides consider me to hold a penchant for a ‘specialist ‘ function that displays individual mindedness and dedication. These are traits that I agree with since I am a instead obstinate individual that does n't wish to alter my head one time I have my head set on something. Mr Robinson, my old employer said †Sung Yin is a really goaded individual with a clear way with where she wants to be and is improbable that she will be swayed from it, † ( Mr. Robinson, 2007 ) . I am ever dedicated to my undertakings at manus and ever give my best to make them every bit good as I can. This has allowed me to develop my accomplishments and cognition to a degree that means I can give a utile part within a squad. Despite what I feel is a reasonably accurate appraisal of my discriminatory functions within a squad, I do non to the full agree with a ‘resource research worker ‘ being my least preferable function. This is because I believe that I am a communicative individual which is a cardinal trait of the resource ‘resource research worker ‘ . As demonstrated by old trial consequences, I am a individual that possesses strong aural accomplishments. Despite regularly following a cautious attack to group treatment activities ( in line with my reflector personality ) , I like to inquire inquiries and take part in activities one time I feel comfy plenty to show my positions one time I have gauged other peoples ‘ point of views.Part 2: Deductions for calling pick2.1 Lifelong LearningEven from a immature age, I have ever been cognizant of the importance of larning new things to broaden my ain cognition base holding been invariably reminded by my parents to â€Å" work ha rd till old, and to larn till old. †A With an of all time altering society and increasing demand for ‘talent ‘ in any professional calling, it is compulsory that an person should non merely get new accomplishments, but to besides invariably upgrade these accomplishments to run into challenges set by the altering work environment.A This is the act of life-long acquisition which is the deliberate patterned advance throughout life of an person, where our cognition is invariably being expanded which allows us to efficaciously ‘survive ‘ in society ( Peter, Jenny and Shelagh, 1998 ) .A The essentialness of life-long acquisition has been good documented even every bit early as the seventeenth century where Comenius wrote that â€Å" no age is excessively late to get down larning. † And that one should ne'er do the error of ‘standing still ‘ in footings of accomplishment acquisition ( Comenius, 1996 ) .A Through my practical experience and l ife in general, I have come to the realisation that uninterrupted acquisition is a necessity to keep a competitory advantage over the many persons that seek the same calling chances as me.A Hence, I search for any chances to better myself through life-long acquisition. With my desire to better, I have late resigned from my occupation to analyze my unmarried man ‘s grade in Northumbria University. Prior to my surrender and subsequent move to partake in full clip surveies, I worked three old ages in the Bank of China as a Customer Service Officer ( Appendix E ) .A During that clip, I was working full-time, while analyzing parttime during eventides by go toing analyzing classes.A The part-time survey has allowed me to develop many cardinal accomplishments to rise my proficiency in making my occupation in minimum time.A This is of import because of the current unstable and competitory occupation market.A It has now become a demand for me to place a clear calling way for me to prosecute and so to develop my cognition towards the relevant countries to carry through the demands of my hereafter employers.A I am now analyzing an ‘International Business Management ‘ degree class with the aspiration to accomplish a future calling in the conc ern sector.A A A A A A Life-long acquisition will assist me supply a solid base for the development of indispensable movable accomplishments ( as discussed subsequently ) that would lodge to me throughout life and to help me in the patterned advance towards my calling ends. It is besides of import for doing me a ‘better ‘ person.A After all â€Å" it is the bottom round of the ladder of personal development. † ( Peter, Jenny and Shelagh, 1998 ) .A2.2 Career ChoiceHaving conducted assorted larning manner trials on myself, I have been able to derive a better apprehension of my acquisition penchants, personality and environments where I am likely to boom upon.A It is expected that cognizing an person ‘s learning manner penchant may assist that individual to define a possible calling way that is best suited for them, or even influence that individual towards certain calling choices.A Indeed, it is common for directors to utilize questionnaires to place ideal personality traits in their campaigners that would most probably be suited for their occupations which would help them in the choice process.A However, it is deserving observing that human behavior is extremely complex, and such trials may non needfully give an accurate or thorough appraisal of an person ‘s personality ( Freud, 2001 ) .A Hence, consequences of these trials should non be held absolute and should merely be used as a guideline to help a individual with respects to doing cardinal determinations such as possible calling waies to take.A Despite obvious drawbacks with utilizing these trials, I agree with most of the suggestions made by them sing my acquisition penchants and some facets of my personality.A In footings of employment, through my practical experiences, I have developed a strong desire to prosecute a calling in Marketing.A The accomplishments I have acquired to day of the month hold mostly influenced my involvement towards this calling way which, together with my personality, has made me see that I possess the ‘raw ‘ foundations to win in the selling sector.A In a study carried out by Honey and Mumford, it was found that the bulk of directors preferable employees that are ‘reflectors ‘ for Marketing occupations ; a trait that they believe would convey the biggest success to their company.A Having carried out a Honey and Mumford trial on myself, it was concluded that I am a strong ‘reflector ‘ , which makes me competently suited for Marketing. ‘Reflectors ‘ such asA myself likes to follow a cautious attack during group activities. This means that I tend to take an initial back place in group treatments, A preferring to obtain different point of views before doing cardinal decisions.A Being cautious, can besides affect believing in front in expectancy of possible obstructions. With selling occupations, it is of import non to hotfoot into determinations without first thought and planning ahead.A This is because, with the nature of the type of work, it is inevitable that there will be ‘lean ‘ periods so therefore, it is particularly wise to be prepared for such periods and to hold a program to move accordingly.A For illustration, a portion of be aftering in front is expectancy of alterations in the markets and happening new merchandises to promote.A It is of import to be cognizant that â€Å" the best selling enterprisers are ever looking for the following large money marker. † They are ever be aftering in front ( Scott Brooks, 2004 ) .A Hence, holding a cautious attack to things can be a good trait as it means that I am less likely to do incorrect determinations due to hotfooting into things and take necessary precautions.A My Belbin consequences that conclude that I have a strong penchant towards a ‘Monitor judge ‘ who likes to measure all options before coming to decisions adds farther support of my suitableness for a Marketing calling. â€Å" The ability to stay unagitated is one of the most sought after personality traits in the Retail profession, † ( John, 2007 ) .A Pressure can come in different ways, for illustration, when covering with unhappy clients who are dissatisfied with the merchandises sold to the ; It is the occupation of the seller to cover with the job and to reconstruct the client ‘s sentiment of the company.A Hence, to accomplish this, it is indispensable to stay unagitated under force per unit area when covering with these situations.A With selling occupations, it is besides of import to be able to react good and suitably to rigorous marks and deadlines that are set and to work towards them, which can besides take to coerce edifice up.A My Belbin trial consequences suggest that I am suited towards a ‘shaper ‘ function which is another ground why I feel that a Marketing calling is suited for me.A ‘Shapers ‘ are adept at executing under supercharging state of af fairss and with the added thrust to win. This is of import since there is a batch of competition within the market.A â€Å" Merely when you have your client on your side, are you able to efficaciously acquire what you want. † ( John, 2007 ) .A I believe this quotation mark highlights what a calling in Marketing is basically all about.A Success within the field of Marketing and Retail is extremely dependent on your clients or clients which means that good ‘people accomplishments ‘ leting you to link efficaciously with both co-workers and clients is essential.A On a personality degree, it is advantageous to be a ‘likeable ‘ individual which can affect being a pleasant person with a ‘cheery ‘ disposition.A â€Å" You are more likely to be able to negociate better if your client likes you, † ( Scott Brooks, 2004 ) .A My MBTI consequences have described me as holding a strong penchant towards extroverted experiencing which means that I like to construct positive relationships with people around me and to make harmoniousness around me.A This, in my sentim ent has contributed mostly to me being a personable individual.A The benefits of this personality trait are double. First, I would be able to sell my merchandises to clients more easy since they are likely to happen me a pleasant individual. Second, I am more likely to be on the ‘right side ‘ of my work co-workers and so they may be more likely to offer me their help.A Having identified a calling field that best suit my personality as based on my personality trials, I seek to accomplish a future calling as a Marketing manager.A A occupation of this sort would let me the duty to do cardinal determinations that will act upon the success of the company.A I crave the chance to pull off a squad, and to give a major part to the company that I work for.A A successful calling as a Marketing director demands certain personality traits in add-on to those mentioned above.A For illustration, it is of import that a Marketing Manager ( Appendix F ) is one that, non merely is able to do accurate opinion, but besides needs to stand by these opinions and non be excessively easy influenced by other people ‘s words.A In other words, they need to be prepared to â€Å" disregard naysayers, even if it ‘s those that are closest to them. † ( Scott Brooks, 2004 ) . Hence, being brave and besides individual minded can be seen as a demand in this sense.A The Belbin trial consequences have identified me as being a ‘specialist ‘ where the cardinal feature of this function is individual mindedness.A With me being a of course obstinate individual who does n't normally alter my head holding made my determinations, I believe I am suited for this peculiar calling pick.2.3 Movable accomplishmentsIn add-on to the right personality and occupation specific accomplishments, a wise employer will besides look to see what movable skills a perspective employee can offer.A The term movable accomplishments merely refers to a set of generic accomplishments in which an person needs in order to be effectual members of a flexible, adaptable and competitory work force and for life-long learning.A â€Å" At the bosom of it all, most employers are looking for people with common accomplishments and features. † ( Phil O'Reilly, 2009 ) .A Unlike occupation specific accomplishments, movable accomplishments can be used in many ways, gained through past experiences.A They are accomplishments that can be used in a assortment of occupations and situations.A In order to be successful in Marketing, there is a repertory of accomplishments that are required for me to efficaciously make my occupation which include clip direction, people accomplishments, leading, teamwork and good organizational accomplishments, amongst others. Marketing occupations rely on the ability to sell merchandises through interaction with a assortment of different clients. Hence, good communicating accomplishments are essential.A As identified by my VARK trial consequences, I have strong aural accomplishments that would be particularly utile in Marketing since the occupation demands that I have a good apprehension of clients ‘ needs.A Bing a good hearer, and besides person that likes to see things from different positions, this would let me to pass on efficaciously with my clients.A My ability to pass on good has been greatly developed through my past employment as a Customer Service Representative at the Bank of China and private coach, learning Mathematicss and assorted linguistic communications to kids. Therefore, good communicating now represents one of my cardinal strengths.A I am tri-lingual giving me versatility in my communicating accomplishments leting me to speak with a wider client range.A Good presentation accompl ishments is besides an of import facet of communicating accomplishment that is required in my hereafter calling since it is likely that It would be needed when advancing new merchandises for instance.A Fortunately, my presentational accomplishments have been greatly enhanced over clip through past experience in giving presentations during my past employment and current studies.A Having a good apprehension of the merchandises that I am advancing and any new merchandises on the market is besides really of import in Marketing.A Hence, it is necessary to hold good research accomplishments and besides to hold an unfastened head with respects to larning new material.A Bing a ‘reflector ‘ agencies that I happy to absorb information from many different angles and utilize it to do my determinations, while being a ‘specialist ‘ as identified by my Belbin trial consequences suggests that I have a natural avidity to larn and spread out my cognition in subjects at hand.A As I am likely to be working within a squad in my work force with similar marks, there is no uncertainty that good teamwork accomplishments are a requirement.A I believe that I possess good teamwork capablenesss holding already been in employment where good teamwork is a must, such as working with my co-workers in the publicity and derivation of comprehensive fiscal programs during my old job.A I besides actively partake in assorted teamwork athleticss that have allowed me to efficaciously construct on my teamwork skills.A It is my mark to accomplish a calling as a Marketing director in hereafter, which will demand extra accomplishments in order to be successful such as leading and ability to actuate myself and others within my team.A Bing a Selling director will intend that I will have greater duty, pull offing a squad or doing cardinal determinations that will impact company success.A Although I believe that I possess an ideal personality to set about such a function in a company, I feel that I will necessitate to better myself farther before I am ready.A With respects to movable accomplishments, I believe my biggest failing lies in my leading qualities, being a less self-asserting person that likes to keep back from engagement in group activities.A I understand that if I am to be a good leader, I will necessitate to better this facet by playing a more outstanding function in group activities and basically ‘stamping my authority'.A I do non to the full agree with the impression that leading is a quality that ca n't be taught, and some people are merely born leaders.A I feel that leading is a accomplishment that can be improved through life-long acquisition and experience ; hence I will boom to better myself in this respect.A â€Å" As with all accomplishments, they need to be learnt and no-one is born with them. † ( Phil O'Reilly, 2009 ) .A A A A ADecisionLife-long acquisition is an indispensable procedure for me to larn new accomplishments and besides to better bing 1s. It is besides extremely of import for my personal development towards being a ‘better ‘ individual, and one that is able to accommodate to an of all time changing universe. The changeless skill of new movable accomplishments is besides critical for calling patterned advance and to give myself a competitory advantage over those booming for the same chances as myself. By utilizing a assortment of different trials, I have gained an grasp of my ain personality, larning penchants and strengt hs. This information, together with my involvements makes me ideally suited for a future calling in the Marketing field.

Transpiration Lab Write Up

Transpiration Lab Write Up Purpose/Question: How do environmental factors affect the transpiration process in plants? Research: Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. Transpiration is not simply a hazard of plant life.It is the â€Å"engine† that pulls water up from the roots to supply photosynthesis (1%-2% of the total), bring minerals from the roots for biosynthesis within the leaf, and cool the leaf. There are four different conditions that affect transpiration. They are wind, humidity, heat, and light. These four conditions may change rate of water loss through transpiration by either losing more water, or less. Plants have adapted to create the C 4, and CAM pathway. In the both pathway the plant takes CO2 and stored.Since CO2 can be taken up and stored for later use in photosynthesis, the plant reduces water loss by having less stomata open during the day since most of its needed CO2 has already been taken up at night. With the abundance of CO2 stored, the plant can then use the stored CO2 for photosynthesis and reducing photorespiration by reducing or completely eliminating accidental O2 uptake. Materials: 1) 5 small plants 2) Fish tank 3) Water spray bottle 4) Water 5) Heat lamp 6) Fan 7) Regular lamp 8) Mass weighter ) Place to record weight Procedure: Place Lamp, Heat lamp, fan, and fish tank in different areas where they won’t affect the other. Spray the fish tank with water and to make a humid environment and keep spraying everyday to ensure the tank is wet. Water all of your plants. Weigh all the plants on the original day, Monday, and record the weight. Place a plant in every condition. With the extra plant, p lace it in an area without a specific condition to use as a control plant. Do not water the plants the rest of the week.Every day, weigh the plants and record its water loss for every plant. At the end of the week, create a chart for the amount of water loss and compare with the control plant. Data Table: Days | Monday| Tuesday| Wednesday| Thursday| Friday| Windy| 108. 2mg| 101. 1mg| 94. 1mg| 89. 7mg| 81. 7mg| Humidity| 103. 8mg| 103. 4mg| 103. 4mg| 103. 4mg| 103. 1mg| Light| 118. 8mg| 112. 1mg| 105. 0mg| 98. 4mg| 92. 9mg| Heat| 104. 3mg| 95. 8mg| 86. 8mg| 78. 7mg| 70. 1mg| Control| 115. 3mg| 115. 3mg| 115. 3mg| 115. 3mg| 115. 3mg| Analysis: Conclusion:Environmental factors, such as heat, humidity, light and wind, affect the rate of transpiration by making the plant loose either more or less water. In conditions such as wind, when there is no breeze, the air surrounding a leaf becomes increasingly humid thus reducing the rate of transpiration. When a breeze is present, the humid air is carried away and replaced by drier air. The opposite of that is the humidity where the plant lost very little water. It lost very little water because its environment was wet, so the plant did not need to diffuse much water.In heat, the air was hot and dry, so the plant lost water because it’s surrounding needed water to cool it down. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises. At 30 °C, a leaf may transpire three times as fast as it does at 20 °C. Finally, light lost a steady amount of water because plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf.I expected these results because it makes sense and I researched before completing the experiment. Some avoidable errors that could have happened would be accidentally splashing water on a plant or putting the conditions too close together. Some unavoidable errors could be the weather outside. Even if the experiment is conducted inside, the hot summer air or cold winter air could drift in the room, affecting the plants transpiration rate. Some further investigations I would make are things such as whether the type of plant affects the rate, or if the type of heat lamp or fan will change the results as well.
