Physics 112 Spring 2014 Phys 112 (S12) Syllabus/introduction 1
Goals Deeper understanding of concepts: less mysterious Entropy Free energy Chemical potential Statistical mechanics fluctuations kinetic theory background <= use of simulations Recognition of physics in a context rich situation, i.e. real life Acquire computational tools Quantitative Problem solving skills Linkages to everyday life bridge between microscopic and macroscopic irreversibility engineering modern physics frontier applications: e.g. astronomy, cosmology condensed matter physics, low temperature History Phys 112 (S12) Syllabus/introduction 2
Participation Focus: Conceptual Understanding We learn by construction /reconstruction of your mental models This process is both intensely personal and social (learn through others) focus on grades, formulae, short cuts Your Role Philipp + I Phys 112 (S12) Syllabus/introduction 3
Participation Before lecture Read book and notes: because of our use of clickers which decreases the in-class presentation time, there will be testing of this reading! Play with applet simulations => intuition. You can suggest others you can find. In class Beginning of class: typically a conceptual question check that you have read the notes focus on a difficult question Peer instruction questions: A conceptual question Vote (with clickers) Discussion in small groups Vote again Active participation during lecture: questions, clickers One minute random quizzes (check attention to the material) Out of class Homework Working groups on problems if you like (but you write your own solution) Start on your own before discussing with others, looking on web! Discussion sections (but try homework first)! Office hours (come with questions) Phys 112 (S12) Syllabus/introduction 4
Partcipation: Clickers Buy or rent a i<clicker at ASUC Store Original i<clicker is fine (multiple choice questions) Register you i<clicker on line http://ets.berkeley.edu/help/register-your-iclicker-remote Option 1 ID is 8 digit ID We will start to use them systematically on Monday Jan 27 Phys 112 (S12) Syllabus/introduction 5
3 consequences: A step towards Flipping the Classroom You will have to read the material before the class! Book (note I do not follow exactly the book, but use the same notations) Notes Other lectures/material on the web: maybe we share this on bcourses Power Point to rapidly summarize the structure of the argument Will take a few of you beyond comfort zone Better than taking notes: add comments on downloaded PowerPoint Not a book: not full sentences, nor word explanations of derivation Only a few derivations in class Phys 112 (S12) Syllabus/introduction 6
Prerequisites Some exposure to thermodynamics Quantum Mechanics not essential Notion of discrete state We will be able to cope with recipe on the number of states 1/h 3 Maths: we will practice Calculus: differentiation, Taylor series partial derivatives integration by part First order differential equation Complex numbers Fourier transform not essential Phys 112 (S12) Syllabus/introduction 7
Difficulties of this course 1) Rusty mathematics we will help you with small exercises (e.g. first sections) 2) Missing the forest for the trees Philipp and I will try to rescue those of you who are getting lost Minute quizzes + feedback Counting quantum states Microcanonical Bolztmann Canonical Do calculation once for all for large systems Classical applications At equilibrium, all quantum states have equal probabilities Phys 112 (S12) Syllabus/introduction Gibbs Grand canonical 3) Real life examples are complex 8 Quantum applications
What would you really like to learn? Try to give at least one example in each category 1) Fundamental concept! 2) Practical application of thermal physics/ statistical mechanics! 3) Emerging phenomena! 4) How did a certain concept emerge historically?! Best would be to give your name so that we can track your answers (no influence on grade) Phys 112 (S12) Syllabus/introduction 9
