Trajectories in Animation, Mathematics, and Physics

• The Week 10 Calendar page is available using the link above. Not counting evaluation week, this is the final week of our program! We are very much looking forward to your final presentations.
• We discussed in detail the schedule and work for this final week in our Week 9 all-program session. Many of you missed this important meeting. You can find the hand-out for that session here. Please consult with your class-mates to fill in the blanks.
• All materials for your final project presentation must be present in the Orca folder by 8:30 am Monday March 11. The presentation order will be selected arbitrarily.

• The Week 9 Calendar page is available using the link above. There are a number of changes to next week’s schedule, so please note them carefully.

• Blank versions of winter quizzes #1 – 6 available under Assignments: Calculus
• Under Assignments: Calculus, in week 8, you will find some suggested problems from the Chapter 5 Review and Chapter 6 Review sections, along with solutions.
• Calculus Winter Exam is on Tue. Mar. 5 from 12:30 – 3:30 in Lab 2, 2242.
• Calculus Exam Reflection is on Wed. Mar. 6 from 11:30 – 1:00 in Lab 2, 2242.

All Campus Mentoring Days March 6th and May 15th , 1:00-4:00 p.m. Before the Academic Fairs on Wednesdays, March 6th and May 15th, Evergreen faculty will host All-Campus Mentoring Day on the Olympia campus is next Wednesday, March 6th from 1-4 pm (the Academic Fair follows immediately afterwards from 4-6). All students are invited to participate in broad, theme-based sessions led by faculty.  New students who participated in the Orientation Week groups that faculty led this past fall will have brief reunions, followed by mentoring and discussion sessions for all students conducted by small groups of faculty.  Each session will be offered twice.  Click here for the schedule.

This is a nice short piece on our work in the program.

• The Week 8 Calendar page is available using the link above. There are a number of changes to next week’s schedule, so please note them carefully.
• The Winter Physics Exam begins Monday February 25 at 9 am, in Lab 2 2223A (**note: new room location**).
• Note that there a number of new posts related to physics below: one about posted versions of blank physics quizzes and make-up quizzes for more practice, one about Physics Problem Set #7 Reflection & Analysis prompts, and one about corrections to the originally posted Physics Problem Set #7 solutions.

Here’s a page collecting together the physics learning goals, quizzes, and make-up quizzes from this quarter.

• The Problem Set #7 Reflection & Analysis prompts were posted later than usual; you can find them here.
• Because they were posted late, the due date is extended. In anticipation of Monday’s exam, I encourage you to complete the first five questions as soon as possible and certainly by Sunday evening, February 24. The required due date for responding to all the questions is Wednesday evening, February 27.
• Several of you have complained about server errors or internet glitches which have caused your carefully composed responses to vanish. That must be very frustrating, and I sympathize. I encourage you to print-out (or otherwise have available) the prompts, and to type up your responses in your standard document editor. Then, you can at your leisure copy and paste your responses into the individual entries in MasteringPhysics.

• There was some mistakes in the originally posted Physics Problem Set #7 solutions – I apologize for my mistake. Thanks to those of you who noticed them and brought them to my attention. If you printed out the solutions prior to 7:00 pm Sun. Feb.24, you have a version with the mistakes. I have posted an updated version with corrections Here are the correction so you don’t need to print out an entirely new version:
  • Problem 2: the originally posted solution mistakenly added 15 + 5 to get 15 GeV for E₃. Of course, 15 + 5 actually equals 20, so E₃ = 20 GeV. This makes u₃ = 0.6c, and m₃ = 16 GeV/c².
  • Problem 5: minor typo error in final answer for E₁. E₁ = 2.0 MeV.
  • Problem 8: the originally posted solution mistakenly used 7.5 GeV/c² as the mass of particle B instead of the 1.0 GeV/c² given in the problem statement. Using the mass given in the problem statement, the corrected mass for particle A should be m_A = 3.414 GeV/c².
  • Problem 9: switched the energies for the left-moving and the right moving photon. The left-moving photon has energy 4 GeV, and the right-moving photon has energy 12 GeV.
