Physics 2D: Eric L. Michelsen

A Word about 2DRelativity and Quantum Mechanics are the pillars of physicsThis class touches the core of physicsConcepts are unfamiliar, perhaps non-intuitiverequires some real thinking on your partBut 2D more than any other course lures students into physics*Physics 2D: Eric L. Michelsen*


A Word about Summer SessionWhose idea was this?Normally, a 4-unit course expects 12 hours/weekBut in summer, its 24 hours/week!6 hours lecture, 4 hours DI/PB, leaves 14 hr/wk for reading, HW, exam prep, office hours, pondering, studyingThis is why only 2 courses are allowed at a time in summerSo buckle up! Were going to all work hardHopefully, these mind-bending ideas will have time to gel*Physics 2D: Eric L. Michelsen*


*Physics 2D: Eric L. Michelsen*Course goalsWe want to understand not just the facts of our topics, but the methods by which people came to understand themAnd so empower ourselves to discover/build/invent and do new thingsWe seek a conceptual and quantitative understanding of basic physics concepts, to allow:Understanding a physical situationDeducing the qualitative behavior of itAssessing what information is available or needed to perform meaningful calculationsPerforming such calculationsVirtually all physical science occupations require such a basic understanding and skillsEmail or talk with me about your course goals


*Physics 2D: Eric L. Michelsen*I Cant Teach You AnythingI guess they picked the wrong guy for this jobYou must learnI can help youWhat is the best way to get a good grade?Understand the concepts!Do homework alone at first, to force thinking on your ownThen get together and explain concepts to each otherIts about concepts and practiceNo one ever learned to play the piano by watching someone else playTherefore, I dont do problems in classYou work problems, with help from Discussion, Problem Solving, Office Hours, and Tutorial Center


*Physics 2D: Eric L. Michelsen*Smart People Ask QuestionsThats how they got that wayWe never look down at questions or incorrect answersBetter to think, risk, and learn, than to do nothing and learn nothingMy job is to provide a safe environment conducive to learning and questionsI take that very seriously


*Physics 2D: Eric L. Michelsen*Take chancesMake mistakesIn classOn exams, not so much


*Physics 2D: Eric L. Michelsen*Schedule of Classes


*Physics 2D: Eric L. Michelsen*Discussion and Problem SessionsSee schedule for timesDiscussion (optional)Wed. 4-6Please bring iClickers to Discussion, though it doesnt affect your gradeProblem session (optional)Thu. 3-5Ends when questions do


Weekly CadenceSummer Session is compressed!480 minute lectures/week, M, Tu, W, Thcome prepared, so we can work on hard parts in lectureDiscussion Wed.: first chance to confront difficultiesProblem Session Thu.: expect you to have done/tried HW so you have targeted questionsHW due Monday, also quizzes/midterm Mondaysproficiency at HW is great practice for quiz/examFinal Exam on Friday, Sept. 4*Physics 2D: Eric L. Michelsen*


ReadingIn order for this to workby work, we mean: master material so you do wellYou need to come to lecture preparedlecture time is not first exposurerather, time to synthesize and masterSo we rely on reading sections ahead of timeLikely to implement reading quiz in TED*Physics 2D: Eric L. Michelsen*


*Physics 2D: Eric L. Michelsen*HomeworkHW is essential for numerical practiceCollected and gradedcheck, check-minus, check-plus (or no check)100% credit on all check; check-plus compensates for check-minusdue on MondaysClass discussion provides a conceptual understanding for numerical calculationsClass discussion alone is insufficient for doing well on the examsHW is assigned mostly from the textbook


*Physics 2D: Eric L. Michelsen*GradingClassroom responseTBD, ~= 10%, optional; modifies exam weightReading quizzesTBD, ~= 5%HomeworkTBD, ~= 15%3 QuizzesTBD, ~= 25%1 midtermTBD, ~= 25%Final Exam TBD, ~= 30%The following grades are a minimum:85%A-75%B-65%C-55%DPlusses and minuses at instructor discretionActual grades may be higher if warranted by overall class performance ...But dont count on itCurves in my previous similar classes were small (avg ~72%)A-AA+B-BB+C-CC+FD?


*Physics 2D: Eric L. Michelsen*Study ideasQuizzes/Exams MondaysStudy ideasPractice problems: HW, past quizzes, iClickersFor each formula:Draw a diagram depicting its use, illustrating every symbol in itDescribe the meaning of each symbol out loud in wordsReview each slide, and say out loud the concept on itEvery slide is there for a reason


*Physics 2D: Eric L. Michelsen*Who am I?Eric MichelsenBSEE: An electrical engineer for a few decadesIntegrated circuits: circuit & device designDigital Signal ProcessingSoftware EngineerPhD Physics UCSD, June 2010Research: Lunar Laser RangingStudy of gravity, aka General RelativityMy book was published in February 2014 from SpringerAvailable at bookstore, and AmazonInterests:Human RightsMedical physicsQuantum Field TheoryScuba diving


*Physics 2D: Eric L. Michelsen*Teaching Assistant (TA)Shauna Kravec: [email protected] will handle: Weekly discussion sessionSome weekly problem sessionsSome gradingOffice hours: TBD; probably Tue and FriRaul Herrera as grader (HW, mostly)


*Physics 2D: Eric L. Michelsen*Who Are You?What majors?What years?Who has had me before?


*Physics 2D: Eric L. Michelsen*TEDiClickerMay share with another classCan not share with another student in this classIf you need to recover its ID, I can help after classEvery class countsRegister your iClicker on TED under Tools, i>clicker Student Registration.R. Harris, Modern Physics, 2nd ed.4 copies on reserve at GeiselHW and reading from textbookHomework: When you send me an email, always include your student IDA23456789Required things


*Physics 2D: Eric L. Michelsen*TEDhttp://ted.ucsd.eduLogin instructions: http://acms.ucsd.edu/units/iwdc/password.html Waitlisted students:You should have access to TED alreadyExtension students see: http://sdacs.ucsd.edu/~icc/ce.phpYou must check your grades on TEDI have to update grades on TED manually~ once per weekYou must notify me within 1 week of posting of any discrepancyYou can configure TED to send you email when I post announcementsSuch as when I announce that HW is assigned


*Physics 2D: Eric L. Michelsen*Electronics in classBe fair to those around you: please dont distract themDuring our class, please open computers for this class onlyIf you dont want to be in class, dont comeNo cell phonesIf you must take a call, sit on the aisles, and feel free to step outside


*Physics 2D: Eric L. Michelsen*OSD StudentsYou must meet with me in week 1 to determine if this is the right class for youEstablish the accommodations for this classExtended exam hours are availableNo late HW


*Physics 2D: Eric L. Michelsen*Waitlisted studentsHistorically, waitlists are highly variableThere are no guaranteesTo be eligible to enroll if space opens up:Pretend you are in the class:Do the iClickersDo the homeworkTake the quizzesetc.


*Physics 2D: Eric L. Michelsen*Physics Tutorial Center2nd floor Mayer Hall Addition, room 2702NE cornerFor hours, see http://tutorialcenter.ucsd.edu/ ~1-5 pm Mon-Thur16 hours/week, drop inIf you have any problem with the Tutorial CenterSend me email immediatelyDate/timeTA on dutyNature of problemSend me good comments, too


*Physics 2D: Eric L. Michelsen*Course AdministrationYou must check the web page every day for updatesSchedules, contact info, etc. are thereI will post the class slides thereWith updates and correctionsPodcasts are online: audio and videoRespect your classmatesNo cell phones in classIf you expect an important call or text, sit on the aisle, and excuse yourself quietly before taking itI will allow computers for nowBut only for class-related workBe fair to your fellow studentsYou must check your official UCSD email regularlyI am required to use it for any private matters, e.g. grades


*Physics 2D: Eric L. Michelsen*No Quiz DropsSummer session is too compressed to afford dropping a quizTo be fair to everyone: No early exams, no late exams, no makeup examsIf you miss a quiz, its about an 8% effect on your gradeconsider it a choice


*Physics 2D: Eric L. Michelsen*No trick questionsLife is tricky enoughEvery quiz/exam question is a description of a situation ...As plainly and simply as I canBut often, there is extraneous informationIts like real lifeWhen real-life is crammed into a short quiz/examquizzes will be about 25 minutes; midterm 80 minutes; final 3 hours


*Physics 2D: Eric L. Michelsen*Academic Integrity: Dont CheatEvery honest student benefits from maintaining high academic integrityPlease read UCSD Policy on Integrity of Scholarship in the UCSD General Catalog, http://www.ucsd.edu/catalog/front/AcadRegu.htmlThese rules will be rigorously enforcedCheating includes Submitting another persons work as your ownCopying from another student on homework, quizzes, or examsKnowingly allowing another student to copy from youUse of unauthorized materials during a quiz or examMisusing iClickersAttempts to manipulate grades unfairly; and intentionally misusing iClickersAny attempt to obtain a higher grade by means other than honest effort


*Physics 2D: Eric L. Michelsen*Academic Integrity (2)The Scarlet Letter: FAny case of suspected cheating will be referred to the Office of Academic Integrity for disciplinary actionAnd may result in an F grade for the courseI have given Fs for cheating in the pastDont make me do it againWhen caught, more cooperation => more leniencyUnlike an F earned by honest effort ...An F earned by cheating cannot be excludedThere is no forgiveness for a dishonest F


*Physics 2D: Eric L. Michelsen*Set subfrequency code 1/2 = A/A (the default). Have you used iClickers before?AYes, and I have mine with me.BYes, but I dont have mine with me now. I promise to bring it every day from now on.CI dont know whatiClickers are.DI dont know how to spell iClicker.EI dont know what class Im in.


*Physics 2D: Eric L. Michelsen*Do you know how to register your iClicker online?AYes, and I will do it tonight on TEDI will use my 9-character Student ID to registerI will use full 8-digit clicker ID, including leading zerosBYes, but I dont have mine with me nowI promise to bring it every day from now on.CI dont know what iClickers areDI dont know how to spell iClickerEI dont know what class Im inIn TED, on the left list, choose "Tools". Then in the lower right corner of the tools pane (you probably need to scroll down), is iClicker Student Registration.


*Physics 2D: Eric L. Michelsen*QuizesFollowing directions is part of the quizWhile you are waiting:Make sure name/ID are on blue book-How to relax your eyes
