Instructional Web Page for Andrew Tomasch
Physics 125 Winter 2008

 

I'm Dr. Andrew Tomasch.
I've been a member of the Department of Physics since 1988. For most of that time I have conducted research into cosmic antimatter (antiprotons and positrons) with experiments flown aboard high-altitude balloons. I also very much enjoy teaching undergraduate physics, and am currently a Lecturer in the Physics Department.

Throughout the semester I will post notes and other items intended to supplement your course work on this site. Please contact me with any problems or questions: atomasch@umich.edu

Physics 125 Discussion Sections 006, 007, 008

Physics 240 students looking for my electricity and magnetism notes and practice exams can click here.

Here is my schedule for the winter 2008 semester.

Office Hours

2:00 pm - 3:00 pm Tuesday and Thursday in the Physics Help Room. On exam Thursdays I will extend my office hours to 1:00-4:00 pm in the Physics Help Room

Our discussion sections will run on the following timeline, where we first discuss the current material and then work problems in groups. The last ten minutes of class are devoted to presentations. Each class, four chosen groups will present their problem at the blackboard, so everybody will see the solutions for all the problems.

Here is a link to the Physics Help Room, located in 1416 Randall Laboratory. Help is available from 9:00 am to 6:00 pm Monday, Tuesday and Thursday, from 9:00 am to 4:00 pm Wednesday and from 9:00 am to 5:00 pm Friday. I hold my office hours in the Help Room on Tuesday and Thursday from 1:00 pm to 3:00 pm. The help room is an excellent resource to help you complete your assignments and become proficient at solving physics problems.

Announcements

The Tau Beta Pi engineering society is hosting tutoring sessions at multiple campus locations on Wednesday evenings. Here is a link to their announcement flier.

Final Exam Review Session

I will hold a review session for our Final Exam on the afternoon of Wednesday April 16 from 2:00-4:00 pm in room 296 Dennison. Bring any and all problems you would like to work in preparation for your final exam!

Exam Week Office Hours

I will hold regular office hours from 2:00-3:00 (or whenever we finish) on Tuesday April 15. I'll hold extended office hours on Thursday April 16 from 1:00-4:00 pm. Bring any and all problems you would like to work in preparation for your final exam!

Special Events

Saturday Morning Physics

Each semester the Department of Physics sponsors a series of public lectures on topics in physics for the general public. I spoke on October 21 and October 28 2006. The topic was "The Physics and Engineering of Model Rockets, Model Airplanes and Flying Toys". Here is a copy of the poster for last semester, and you can click here to keep up to date on the lecture series each semester. Finally, here's a direct link to my talks, archived online. You can see both the slides and video for both talks. You will need RealPlayer to view them.
