  1. Physics 215–Elementary Modern Physics Topics Covered: • ¼ Special Relativity • ½ Quantum Mechanics • 1/12 Nuclear Physics • 1/12 Special Topic #1 • 1/12 Special Topic #2 Everyone Pick Up: • Syllabus • Student Info sheet – fill it out Physics Dept. Talk Wednesdays • Munchies at 3:30, lobby • Meeting at 4:00, Olin 101 http://users.wfu.edu/ecarlson/modern https://www.webassign.net/student.html 8/27

  2. Physics 215 –Modern Physics Eric Carlson “Eric” “Professor Carlson” Olin 306 OH: Tues & Thurs 1-2 or by appointment 758-4994 ecarlson@wfu.edu Materials • Modern Physics, 6th ed., Tipler and Llewellyn • Webassign access • Scientific Calculator • Laptop http://users.wfu.edu/ecarlson/modern

  3. Dr. Carlson’s Approximate Schedule Monday Tuesday Wednesday Thursday Friday 9:00 10:00 11:00 12:00 PHY 741 PHY 741 office hour office hour PHY 741 1:00 office hour PHY 215 PHY 215 office hour PHY 215 2:00 research research research 3:00 Free food 4:00 colloquium 5:00 • I will try to be in my office Tues. Thurs. 1-2 • When in doubt, call/email first

  4. Preparing for Lecture Reading Assignment • Sections 1-1 and 1-2 by Friday • Sections 1-3 and 1-4 by Monday • Read the material assigned on the Web, or in class each day, before class starts • Read the reading quiz, posted on Webassign • Take a Webassign-based reading quiz online by 9:30 AM https://www.webassign.net/student.html Quizzes: • Reading quiz A by Friday • Reading quiz B by Monday

  5. Class attendance and seating • Attendance is expected every day • More than two unexcused absences count against your grade • If you have an advance excuse, contact me (email) • If you are ill, call/e-mail me OR bring Doctor’s note • Starting Monday, everyone will sit in the same seat every day (your choice which seat)

  6. Class Participation • Everyone is expected to participate in class • Come prepared • Ask questions • Volunteer to answer my questions • If you don’t ask me questions, I’ll ask you questions Homework • About 1-3 problems per homework set • Almost always Webassign – online • Eight chances on most problems • Due almost every day at 9:30 AM, starting Monday • Getting help is encouraged • Ask a friend • Ask me • Don’t copy – this is an honors code violation Homework: • Homework A by Monday

  7. WebAssign • Hints on using WebAssign are on the web • Logging in: • Username = Wake email address without @ wfu.edu (mine is ecarlson) • Institution = wfu • Password = student# (until you change it) • Note – the final digit on your ID is not part of your student number • Answers input usually must be better than 1% accuracy • Suggest doing calculations to 4 digits, input at least 3 • Numbers can be put in scientific notation • Enter 299792458 as 3.00E8 • Equations – input with *, /, +, -, and ^. • Volume of sphere of radius r: 4*pi*r^3/3 • See me if you are having problems

  8. Labs • No lab for this course, but PHY 265 is normally taken at the same time • Dr. Keith Bonin is in charge • Labs started yesterday Substitute on Monday Dr. William Kerr

  9. Exams Exam Dates: September 19 October 15 November 10 December 12 • 3 tests and a final • Honors code violations will be turned in to the honor council • Normally, penalty is 1-term suspension and an irreplaceable F in the course • Part multiple choice, mostly short answers and worked problems • Old tests on the web • If ill, call me/email me immediately or bring a Doctor’s note Solid Red Line – Memorize this formula Dotted Red Line – Easily Derived from Other formulas Dashed Red Line – Know how to use it Other colors – not on test

  10. Percentage Breakdown: Test 1 12% Test 2 12% Test 3 12% Final 24% Homework 30% Class Part. 5% Read Quiz 5% Grades Grade Assigned 94% A 73% C 90% A- 70% C- 87% B+ 67% D+ 83% B 63% D 80% B- 60% D- 77% C+ <60% F • Little if any curving • Do not allow extra credit

  11. The Web http://users.wfu.edu/ecarlson/modern Numerous materials can be found on the web for this course • These lectures • Handouts: • Syllabus • Math Review • “Units” constants and other information • Introduction to WebAssign • Old tests and test information Emergency contacts: Web page email Cell: 336-407-6528 Home: 336-724-2008 Pandemic Plans • If there is a catastrophic closing of the university, we will attempt to continue the class:
