Learning objectives
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 dentists, such as: centrifuges, endoscopes, microscopes, transducers for
ultrasound equipment, laser systems, radiology equipment and NMR, radiation
detectors, etc. As its final, but perhaps most important, goal, the course has been
designed to stimulate students to become more familiar with certain common
concepts, but which are not always sufficiently explained in previous study, such as:
mechanical action between bodies in contact, exertion and energy in action,
dynamic aspects resulting from elastic force and impact, friction and thermal and
thermodynamic aspects, static and dynamic properties of gaseous and liquid fluids,
light and its manifestations, including in relation to the structure of the eye and its
physical defects; fundamentals of electrical, magnetic and nuclear phenomena, the
laws that govern potential and current; electromagnetic and nuclear radiation,
perturbations induced in means passed through and aspects of detection and
control.
