Course Objectives
- The main objective of this course is to show that Newtonian mechanics is an approximation theory, and cannot accurately describe the physical behaviour of our universe. Two regimes where Newtonian mechanics fails to accurately predict the physical outcomes are i) when the bodies are moving near the velocity of light and ii) when the size of the system is relatively small. In this course, we will see that in order to describe these two regimes accurately, we need to understand the ideas of special relativity and quantum mechanics.
- To introduce the idea of Einstein's special relativity and to see how special relativity modifies Newtonian mechanics at high velocities.
- To introduce various experimental results that lead to the development of quantum mechanics.
- To introduce the ideas of wave-particle duality in elementary particles, Uncertainty principles and their applications. <br /> <br />5. To understand Schrödinger’s wave equation, and how to solve them in different physical situations
Course Outcomes
On completion of the course, the student should have the following learning outcomes <br />1. Newtonian Mechanics is the approximate theory which is valid for small velocity and macroscopic bodies. <br />2. Basics of special relativity, and its predictions such as length contraction, time dilation, mass-energy equivalence etc. <br />3. The experimental evidences for the inadequacies of classical physics, wave-particle duality and the idea of uncertainty principle. <br />4. Concept of wave functions and their physical interpretation for matter waves. <br />5. The time-dependent and time-independent Schrödinger equations and their solutions for different potentials.
