The paper considers special aspects of technical translation and peculiarities of engineering terminology interpretation in English-Russian language pair correlation. Problems of adequate translation of general and specialized words, vector of compound lexical elements in engineering context, text production and inversion in the English and Russian languages, transformations in technical translation with compression and addition techniques are analysed. Preference of building English engineering terms with common words, mainly the "noun-noun" group is highlighted.

In exploring the epistemology of engineering science, we propose a model of engineering. This model incorporates the goals of engineering, the approach to engineering (also called the engineering method) and the role of experience in engineering. The basis for understanding the nature of engineering science will be explored, and will be contrasted with natural science. To begin, a large-scale engineering project that was successfully completed in Ireland many years ago is discussed - specifically, the development of a megalithic passage tomb as an exemplar of the engineering method in structural design, project management and aesthetics. This exemplar firmly demonstrates that engineering method existed before the development and understanding of the relevant natural science. We next contrast the nature of engineering or engineering science and natural science. This discussion will further develop the engineering model, but will contrast the philosophical differences between engineering and science. We then return to build upon the 'engineering model' through the modern day exemplar of the development of the jet engine, demonstrating that invariably multiple factors, including creative design initiatives from different sources, global, political, economic and cultural circumstance, and the passage of time contribute to the evolution and success (or failure) of large sustainable scientific and engineering projects. In conclusion, the engineering model is mapped to a philosophical model demonstrating that philosophy is as relevant to engineering as it is to other fields.

Abstract for the PAWS Women in Science & Engineering Event at which Sandy Black delivered the lecture: New jobs, new skills and new consumer choices are emerging as governments, employers, organisations and individuals work towards a low carbon future. And further change is needed in manufacturing and lifestyles if the UK is to meet agreed targets for the reduction of CO2 emissions - 80% by 2050. From fashion to farming to forging new materials. the degree to which this new culture will permeate our lives is only just being appreciated. This PAWS (Public Awareness of Science) evening introduced some of the women scientists and engineers working to meet this challenge. It also looked at the challenges involved in communicating the issues surrounding a low carbon future to a wide public.
