Learning objectives
Introduce the student to the study and application of the scientific method, the basic research tool in any field of science. 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 ultrasound equipment, laser systems, radiology equipment, TC, NMR.
