Learning outcomes of the course unit
The course has been designed to provide an introductory basis for other major degree fields including Chemistry, Biology, Physiology, Biochemistry, etc., as well as the physical phenomenology on which they are based or which they make frequent use of.
The course will also provide the conceptual basis for understanding a number of major technologies that with increasing frequency are used by doctors and technologists such as: microscopes, transducers for ultrasound equipment, laser systems, radiology equipment and NMR, radiation detectors, etc.
