The word science originates from the latin word «scientia», meaning knowledge. science is simply a way of looking at the world. it consists of asking questions, proposing answers and testing them against the available evidence.a popular astronomer carl sagan wrote: «science invites us to let the facts in, even when they don’t conform to our preconceptions. it counsels us to carry alternative hypotheses in our heads and see which best match the facts». science is a human construct and human ability. students of science major in various fields of science. they take part in r& d at their institutions. the faculty and staff at the universities and institutes will help the students as they fulfill their academic and professional goals. research advisors — well- known scientists will help their students with research. graduate students spend most of their time in independent study and original rsearch. fоr example, graduate studies in the usa can be divided into two phases: phase i leads to master's degree and consists of lecture-type coursework. this degree is usually required in fields such as engineering, library science etc. the mba, or master of business administration usually takes two years. these degrees are considered stepping stones toward a phd. normally few, if any laboratory courses are offered. a thesis, calling for significant research and/or design effort may be required. phase ii leads to doctoral degree — phd (doctorate). students who are enrolled in a doctoral program are known as phd candidates. they will spend some time in class, but the most important work is spent in first-hand research. it may take three years or more to earn a phd degree. this degree normally requires four to six years of study beyond the bachelor's degree, culminating in lengthy, in-depth, original research of a specific topic, which may be both theoretical and applied, or purely theoretical. usually, doctoral studies focus very heavily on developing advanced scientific skills. a phd dissertation is considered a unique, original contribution to human knowledge. this paper must contain views, research or designs that have not been previously published. the best and the most suitable methods, techniques, approaches and procedures should be used. several research publications on issues relevant to the investigation should be prepared. most universities awarding the phd degree also require doctoral candidates to have a reading knowledge of two foreign languages, to pass a qualifying examination that officially admits candidates to the phd program, and to pass an oral examination on the same topic as the dissertation. if the dissertation meets all the requirements it will be accepted and approved by a special board of academics after oral defense.most scientists spend many years studying and working in laboratories. scientists can work individually or in a team. in many cases, scientists are devoted to their work and may find little time to do other things. usually scientists are involved in studying various aspects of their fields and work on one or two major projects at one time. 1. what is the theme of your research? 2. where is the research material taken out? 3. what is the practical importance of your scientific investigation? 4. what are the main thesises of your research? 5. who is your research advisor?
