Fundamental of Physics

Physics is one of the more fundamental scientific fields, and electrical engineering spans much of it. Electromagnetism is obviously very relevant to electrical engineering, but other parts of physics are also important. Since light is a form of electromagnetism, optics is important not just to lasers and their applications but to optical and radio communications more generally. Semiconductors (transistors, diodes, integrated circuits, solar cells, etc) all rely on "solid state physics", which in turn relies on quantum physics. Even relativity has important engineering applications. Not only is it the modern way to understand electromagnetism, it is an everyday engineering reality in modern satellite navigation systems. In fact, modern satellite engineering is a highly interdisciplinary field that applies just about every aspect of physics plus mathematics, communication theory, computer science, mechanical and aerospace engineering.
