1、1 CHEMISTRY AND CHEMISTWithout chemistry our lives would be unrecognisable, for chemistry is at work all around us. Think what life would be like without chemistry - there would be no plastics, no electricity and no protective paints for our homes. There would be no synthetic fibres to clothe us and
2、 no fertilisers to help us produce enough food. We wouldnt be able to travel because there would be no metal, rubber or fuel for cars, ships and aeroplane. Our lives would be changed considerably without telephones, radio, television or computers, all of which depend on chemistry for the manufacture
3、 of their parts. Life expectancy would be much lower, too, as there would be no drugs to fight disease.Chemistry is at the forefront of scientific adventure, and you could make your own contribution to the rapidly expanding technology we are enjoying. Take some of the recent academic research: compu
4、ter graphics allow us to predict whether small molecules will fit into or react with larger ones - this could lead to a whole new generation of drugs to control disease; chemists are also studying the use of chemicals to trap the suns energy and to purify sea water; they are also investigating the p
5、ossibility of using new ceramic materials to replace metals which can corrode. Biotechnology is helping us to develop new sources of food and new ways of producing fuel, as well as producing new remedies for the sick. As the computer helps us to predict and interpret results from the test tube, the
6、speed, accuracy and quality of results is rapidly increasing - all to the benefit of product development. It is the job of chemists to provide us with new materials to take us into the next century, and by pursuing the subject, you could make your positive contribution to society.Here are some good
7、reasons for choosing chemistry as a career.Firstly, if you have an interest in the chemical sciences, you can probably imagine taking some responsibility for the development of new technology. New ideas and materials are constantly being used in technology to improve the society in which we live. Yo
8、u could work in a field where research and innovation are of primary importance to standards of living, so you could see the practical results of your work in every day use. Secondly, chemistry offers many career opportunities, whether working in a public service such as a water treatment plant, or
9、high level research and development in industry. Your chemistry-based skills and experience can be used, not only in many different areas within the chemical industry, but also as the basis for a more general career in business.1 As a qualification, chemistry is highly regarded as a sound basis for
10、employment. You should remember that, as the society we live in becomes more technically advanced, the need for suitably qualified chemists will also increase. Although chemistry stands as a subject in its own right, it acts as the bond between physics and biology. Thus, by entering the world of che
11、mistry you will be equipping yourself to play a leading role in the complex world of tomorrow. Chemistry gives you an excellent training for many jobs, both scientific and non-scientific. To be successful in the subject you need to be able to think logically, and be creative, numerate, and analytica
12、l. These skills are much sought after in many walks of life, and would enable you to pursue a career in, say, computing and finance, as well as careers which use your chemistry directly. Here is a brief outline of some of the fields chemists work in: Many are employed in the wealth-creating manufact
13、uring industries - not just oil, chemical and mining companies, but also in ceramics, electronics and fibres. Many others are in consumer based industries such as food, paper and brewing; or in service industries such as transport, health and water treatment. In manufacturing and service industries,
14、 chemists work in Research and Development to improve and develop new products, or in Quality Control, where they make sure that the public receives products of a consistently high standard. Chemists in the public sector deal with matters of public concern such as food preservation, pollution contro
15、l, defence, and nuclear energy. The National Health Service also needs chemists, as do the teaching profession and the Governments research and advisory establishments. Nowadays, chemists are also found in such diverse areas as finance, law and politics, retailing, computing and purchasing. Chemists
16、 make good managers, and they can put their specialist knowledge to work as consultants or technical authors. Agricultural scientist, conservationist, doctor, geologist, meteorologist, pharmacist, vet . the list of jobs where a qualification in chemistry is considered essential is endless. So even if you are unsure about what career you want to follow eventually, you can still study chemistry and know that youre keeping your opti
