Brand new concepts on space and time phenomena along with the real working principles of nature leading to a complete revision of our contemporary understanding of the universe and hence changing engineering applications radically will be studied. Student will start exploring the fascinating world of Modern Physics which contains many surprising results contrary to our intuition. Consequently, a basis on being able to understand the real physical nature behind the fundamental Science and Engineering disciplines, especially Electrical and Electronics Engineering, will be established. In the previous Physics classes of this program, Newtonian classical physics laws dated about early 1700s have been learned previously. But in the early 1900s, since classical physics is insufficient to explain some natural phenomena like black-body radiation, electromagnetic spectrum, nuclear radiation, etc., some scientists like A. Einstein, M. Planck, W. Heisenberg, etc. come up with some brand-new theories to explain these unexplained phenomena. These theories have been improved in the 20th century and become a basis of our modern today’s physics laws to be a basis of our today’s modern engineering applications, like sensor technologies, semiconductor technologies, data storage technologies, energy technologies, satellite, optic and other communication technologies, etc. To illustrate, the LDR (Light Depending Resistor) sensor technologies in the entrance gates of our today’s modern buildings sensing that we approach the entrance gate to open it works on the modern physics laws especially postulated by the M. Planck for the first time (photoelectric effect). Students who take this course will start understanding conceptually these real physics laws, that is the modern physics laws, which works entirely different than the classical physics laws especially in the micro and macro world and cannot be understood by our daily senses. Moreover, student who takes this course will learn when and under what conditions those old classical physics laws become valid. When the modern physics laws are learned, it will be easier to understand the working principles of our today’s engineering applications. In this respect, this course is strongly recommended for students to make-up and fill their insufficient knowledge in the field especially for the compulsory courses like EE204, EE206, EE307, etc. Especially, following concepts are aimed to be learned in this course: “What is wave motion and how it is formulated (we will use the same formulations in course EE307), what is sound wave, what is light wave, what is photon, what is particle behavior of light and what is wave behavior of light, when light exhibits particle behavior and when wave behavior, when is the classical physics invalid, which natural phenomena cannot be explained by the classical physics and how they can be explained by the modern physics (some of them will be studied in this course), how can very small and huge distances be measured, how does an electron move in reality (why do classical physics laws not work in the micro world?), how much can a microscope magnify and what is its resolution power, what is the probability of existence of a particle in space and what is probability waves, what is their relationship with the electrical parameters, when and how energy is quantized in nature, when and how a particle tunnels in nature, what is electron tunneling, etc. ???”Note: This course is taught in the introductory level and next to this course is being taught as an elective course with code EE488.
