Wiley & Sons Supplementary Texts (only suggested for further reference, not required): Halliday, Resnick & Krane, Physics, 5th edition, J. Wiley & Sons Young & Freedman, University Physics, 11th edition, Pearson/Addison-Wesley Term Work: Homework – roughly every second week – due back two weeks later. One 1-hour midterm will be scheduled during class on March 4, 2008. A final exam will be scheduled during the April 2008 finals period, the exact date will be announced in time. Evaluation: Homework 30% midterm 30% final exam 40% Further important information, such as downloadable lecture notes, homework assignments, course news, etc … can be found on the course homepage: http://www.physics.umanitoba.ca/undergraduate/phys2250/index.html Access to this website is important, and if you have problems visiting it regularly, please see me immediately. Introduction to Modern Physics Winter 2008, M. Gericke • “Old” (or classical) vs. “modern” physics, short overview • Einstein’s theory of special relativity • Early quantum physics (Bohr-Rutherford atom) • Particle-wave duality • Modern quantum mechanics, Schrödinger equation • Atoms and molecules • Nuclear physics • Elementary particles Initial Remarks • Read chapter 1 of Krane for a review of classical physics, units etc. If you are not familiar with the concepts in ch. I, talk to me. • In addition to assigned homework, you are encouraged to tackle as many problems as you wish (obviously), and you can consult me about them during office hours. Example 2.1: Two cars are traveling a constant speed along a road in the same direction. Car A moves 60 km/hr and car B moves at 40 km/hr, each measured relative to the ground. What is the speed of car A relative to car B ? Example 2.2: An airplane is flying due east relative to still air at a speed of 320 km/hr. There is a 65 km/hr wind blowing toward the north, as measured with respect to the ground. What is the velocity of the plane relative to the ground?
