Monday 8/25/08 On board: Steven.pollock@colorado.edu and oliver.dewolfe@ www.colorado.edu/physics/phys3220 Exam dates: Tuesday 7-9:30 pm, 9/30 & 11/11 HW due on Wed!! Office hours: Fri, Mon, Tues (figure out good times) Reading: Griffiths Preface and 1.1-1.3, and/or lecture notes pp. 1-10 ___ Topics: [ Introduction, syllabus : Ask questions ! Prerequisites are 2170, 2210 and 3210, plus differential equations and linear algebra. Talk to me if you have any possible deficiencies. White boards: What is QM Must cover: text, 1st hw logistics, exams, choice & importance of text (and QM as "sea"), clickers & discussion in class, office hours (come!), lecture is about sensemaking. Notes: Discussion of “where QM fits” (speed and scale), and essence of classical mechanics (particle trajectories) _______________ Wed 8/27/08 On board: www.colorado.edu/physics/phys3220 Reading: Griffiths 1.3 & 1.4, and/or lecture notes p. 11-19 (and through p. 26 if that freshman physics material is not familiar!) (ON board) Topics: Postulates of QM, ACTIVITY : Clicker questions _______________ Fri 8/29/08 Check in with SG about permission forms - maybe remind/ask for last ones On board: Monday is a holiday! Tut today @4 (basement), (Announce!) Office hr Tues@3-5 11th floor Reading (for Wed): Griffiths 1.4, lecture notes “Ch 1 part 2” (ON Board): Prob (finding particle between x1 and x2) = integral_x1^x2 (psi^2(x) dx) Topics: Statistics: Prob, <x> ,sigma, for discrete and continuous distributions. Activities:

Monday 9/2/08 HOLIDAY _______________ Wed 9/4/08 MUST FIGURE OUT NEW TUTORIAL TIME Reading: Griffiths 1.5, 2.1 (??), and/or lecture notes Ch 2 part 1, p. xxx ON BOARD: Topics: Complex #'s, classical waves, superposition _______________ Fri 9/6/08 On board: Tut today @ 3 PM, or 4 PM (basement), ( Reading (for Mon): Griffiths 2.1-2.2, lecture notes “Ch 2 part 1, and start of part 2” (ON Board): traveling wave: f(x-vt), wave equation d^2y/dt^2=v^2d^2v/dx^2 Topics: Linear operators, then some history:, deBroglie. Intro to SE, motivate it, talk about pieces. Activity: WHITE BOARDS: First, do the “deBroglie” trick to get n lambda = 2 pi r for a wave on a circle, thus L = n hbar Second, come up with an operator to “extract” the energy from a plane wave.

L6: Monday 9/8/08 Reading For Wed: Griffiths 2.1 (could start 2.2) and/or lecture notes Ch 2, part 1 (up to p2. 7) (ON Board): EXAM dates! E = hbar omega = h f P = hbar k = h/lambda Covered notes 1.C.1-1.C.7 Topics: O perators/eigenvalues , and introduce the Hamiltonian, KE, and momentum as operators . (So, first time seeing p = -I hbar d/dx: motivate it from deBroglie, but also from <p> = m d<x>/dt) Talk about normalizing the wavefunction (and that this is true at further times – don’t work it out, just discuss, they do it on hw) I also talk about the expectation value of Classical operators (the game in which you replace Q(x,p) with Q(x, hbar/i d/dx) _______________ L7: Wed 9/10/08 Reading: Griffiths 2.2, and/or lecture notes Ch 2 part 2 (up to page 2.16)
