COURSE GOALS: This course gives an overview of the basic multidisciplinary aspects of Physical Science. In the area of Solid State Physics in particular, it aims at teaching all the fundamental scientific concepts essential to Solid State Engineering and preparing the students for the Bachelor of Science so that they are capable of taking more advanced courses in this field. The students are led from the understanding of electrons in an atom, atoms in a crystal, and crystal group theory, to that of quantum mechanics for the design of electronic and optoelectronic devices.
