Introduction to selected topics in Modern Physics explores some major sub-disciplines of modern physics and their (potential) applications in industry/research. Students learn why society invests so much in physics and what it gets in return, from the origins of electronic devices and novel materials tackling the energy crisis to the large-scale structure of our universe. Students will build up an understanding that modern technologies are developed based on physics, i.e., application of laser in medical treatment, magnetic levitation, etc. This course serves as an introductory course to give them a taste of modern physics and to inspire their interest in physics. Students will work both independently and in small groups to solve problems, prepare and present outreach-style essays in a peer-reviewed approach.
