One of the most celebrated concepts in the scientific history developed by the most known Physicist Albert Einsteine and predecessors, have even found its place in Hollywood movies such as Interstellar and so on. Though there will be some concepts and constructs in the subject which a layman find it difficult to digest, we would rather deal here with the fundamentals and most realistic implications of the Special theory of relativity.
Second part of the course is Spectroscopy which is at the heart of many science disciplines. It is the way by which human kind get to know the details of accessible material world around him and the inaccessible celestial world alike. It is also the best transition from black-board physics to the details of the structure of matter at the molecular, atomic and subatomic levels and their perceivable manifestation as the interaction with radiation. Spectroscopy is where knowledge on other branches of physics such as quantum mechanics, statistical physics, and electrodynamics is put to practice.
