23. Essay: “modern problems of scientific research”

The development of modern science is characterized not only by an unusually rapid accumulation of new knowledge but also by the fact that the principles and methods of scientific research have changed essentially and are continuing to change. Among the concepts which reflect this process most intensely, a special place is accorded to the notions of system and structure. Externally this is reflected in the circumstance that the terms designating these notions have become most widespread in scientific and popular literature. A linguist cannot write a few sentences without mentioning the language system; the chemist without mentioning the structure of combinations; the cybernetician without referring to systems of control; the biologist without referring to the structural aspect of organisms; and all of them use these terms with capital letters, as it were, endowing them with special profound meaning.

This is not simply a matter of fashion. The study of entities as structures and systems has become in our time a fundamental problem relevant to all sciences. This direction in methods of understanding, or, one might say, of "perception" of entities began to be formulated already long ago; but it is only in the second quarter of the twentieth century that a real revolution of views occurred and the new direction spread and received universal recognition.

The triumph of this new point of view and the broad transition to system subject matter and system problems resulted not only from the internal development of the sciences themselves but largely also from the development of modern industry. A characteristic feature of our days is the "large scale" technical system, often intricately automated and served by extremely complex electronic computers.

24. Essay: “Describe the current sources of information for scientific writing”

‘Keeping up with the literature’ is a common obsession of successful scientists. That ominous phrase ‘the literature’ generally refers to the published journal and review papers on a particular subject. A journal paper reports the results of original research. As an undergraduate you will be required to write reports on laboratory and fieldwork; these correspond in purpose and style to journal papers. A review paper presents the previously published facts and theories in a particular field but is more than a mere catalogue of previous literature. A good review is a critical summary or synthesis of the current knowledge in that field. It should highlight areas in which further research should be carried out and should stimulate readers to carry out this research. It should point out any deficiencies or inaccuracies in previous research. The author of a review is free to use his own interpretation and opinion, e.g. ‘I believe Brown (1980) is mistaken because ...’. Such interpretations must be supported by sound reasoning (note the word ‘because’) and normally result from years of experience in the field. As an undergraduate you will write essays or literature reviews, which correspond to review papers. You do not have the experience of the average review author but it should still be possible to inject some originality into your review, rather than just presenting a catalogue of facts. You can reassess the conclusions of the original authors in the light of more recent knowledge and compare and contrast the results and conclusions of different authors.
