There will usually be five people in the room to help out (instructor, grad & two undergrad TAs, and demo-group member).Experiments: Wed. second hour• Pre-experiment question part of problem set.• Carried out by groups of three, in class.• Laptops with DataStudio and other software; most experiments will interface to laptops.• Conceptual Report due at end of experiment.• Post-experiment data analysis part of problem set.Expert Problem Solving•Mon: In class problem solving session, basics.• Tues: Problem Set due at 4 pm.• Thurs: Mastering Physics assignment (due at 10pm) advanced problem solving.•Fri: In class problem solving session, advanced.• Sun 1-5 pm : Tutoring.•Sun: Mastering Physics assignment (due at 10pm) introduction to weekly material.ScheduleMastering Physics due: 22:00Mastering Physics due: 22:003 tests (19:30-21:30): Sep. 30, Oct. 28 and Nov. 18Evening13:00-17:00Problem set due by 04:00pm AfternoonHour1 (11-12): Advanced problem solvingHour1 (10-11): LectureHour2 (11-12): ExperimentHour1 (10-11): LectureHour2 (11-12): ProblemMorningSundaySaturdayFridayThursdayWednesdayTuesdayMonday• Tests + Final Exam 45%+20% Individual• Homework PS 10%• Mastering Physics 10%• Experiments 5%• In class work and PRS 10%Grading policy: Weighting schemeF < 60D ≥ 60C- ≥ 63C ≥ 66C+ ≥ 69B- ≥ 73B ≥ 77B+ ≥ 81A- ≥ 85A ≥ 90A+ ≥ 95Grading policy: BreakpointsA cannonball is shot straight up (not recommended). At the top of its trajectory:1. It’s acceleration is zero, but not its velocity2. It’s velocity is zero as well as its acceleration3. Neither its velocity nor its acceleration is zero4. It’s velocity is zero, but not its acceleration5. Both its acceleration and its speed are zeroPRS question• 50 minutes for diagnostic test, interrupted by lab tours of 25 min (so 75 min total)Pre-Class Diagnostic TestTours of BEC Experiments• Students from 3 tables (at a time) will go upstairs to look at Bose-Einstein Condensate experiments at the Center for Ultra Cold Atoms http://www.rle.mit.edu/cua/default.htm• Video of Prof. Wolfgang Ketterle Lecture on BEChttp://mitworld.mit.edu/video/77What is % differencein temperature betweensummer and winter?15 % (Kelvin!)i.e. - not much!Ratio of hottest to coldest?Temperature Scales++lasercoolingevaporativecoolingadiabaticcoolinglaboratory systems | natural systemsWhat is BEC?
