This second edition has been updated to cater for the new GNVQ in Engineering. It covers the units "Science and Mathematics for Engineering" at intermediate level and "Science for Engineering" at advanced level. It also more than covers all the objectives of the science units for engineers in BTEC National courses, and is a suitable textbook for the many pre-degree "foundation" courses now being run. This text explains the scientific concepts, and their applications, that are essential and basic to coursework. Clear and concise explanations are supported by worked examples and further problems (with numerical answers provided).
