1 Physics 112 Spring 2014 Phys 112 (S12) Syllabus/introduction 1

2 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

personal and social (learn through others) focus on grades, formulae,

3 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

4 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

5 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 Option 1 ID is 8 digit ID We will start to use them systematically on Monday Jan 27 Phys 112 (S12) Syllabus/introduction 5

6 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

7 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

8 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

9 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

11 Logistics Lectures complementing Kittel and Kromer: Thermal Physics MWF 8:00-9:00 3 LeConte Hall Lecture notes Lecture notes on line (Advice: download before class! I will try to make available 1 day in advance) Web site : or on physics web page Office Hours Bernard SADOULET 439 LeConte Mo 9:00-10 and Wed 4:10-5:30 + appointments sadoulet at berkeley dot edu (please use Physics 112 in title) or better use bcourses Cell in case of emergency: Homework!!! Due Friday 5:00 pm Homework for following week posted in principle Friday night Discussion sections: being restructured Highly recommended for undergraduates Monday 10:00-11:00 70 Evans Wednesday 3:00-4:00 9 Evans Graduate Student Instructor Philipp Dumitrescu philippd at berkeley dot edu Office hours TBD Phys 112 (S12) Syllabus/introduction 11

12 Work Load &Grading 4 Units => 10 hours -4 6 hours/week 1h30 reviewing notes and reading text books 2h30 homework 2h (in average, i.e. 7h for each ): preparing midterms and final exam 3 Midterms during class with notes February 28 (1 page), March 21 (2 pages), April 25 (3 pages) Final with notes (4 pages) Grading 10% participation (good incentive to come to class in spite of the early hour + office hours and discussion sections) Clickers will help control attendance 40% Homework 3x (25/3)% each midterm 25% Final exam Phys 112 (S12) Syllabus/introduction 12
