What engineers actually do and their vital role in society is understood by too few young people, their teachers or parents. "Molecules to Monoliths. How engineering careers make (almost) everything happen." explains the structure of engineering and the part of professional engineers in it. Steve Taylor has devised a simple algorithm, "The Engineering Family", to clarify the relationship between the engineering disciplines and engineers' operational roles in supporting successful manufacturing and construction industries. The book is designed as an introduction to a career in engineering to be browsed as a simple reference where the reader can go back and forth finding things that match their particular interests and thus help decide on the type of higher education course for them. It is also aimed at encouraging readers undecided on a future career path to seek out more detail such as that available on the websites of the engineering institutions and through workshops organised by major engineering companies. The demand for people qualified with engineering knowledge and skills is enormous. For school-leavers with a maths and science background, engineering and manufacturing present a significant opportunity for a viable, well-rewarded and exciting career. As it says on the front cover to this book 'engineering is the ultimate multiple choice career'.
