Instructional Web Page for Andrew Tomasch
Physics 125 Winter 2009

 

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

Here is my schedule for the winter 2009 semester.

Office Hours

2:10 pm - 4:30 pm Monday
2:10 pm - 4:00 Wednesday

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.

Special Events

Tutoring Offered by Tau Beta Pi

The Tau Beta Pi engineering honor society is offering tutoring for introductory physics courses this semester every Sunday afternoon, at a variety of locations on north and south campus.

LSA Theme Semester:
The Universe--Yours to Discover

The winter 2009 semester has been designated an LSA theme semester focusing on astronomy and astrophyiscs. The year 2009 marks the 400th anniversary of Galileo's first historic glimpse of the heavens through a telescope. There are many outstanding lectures and exihibitions for the general public associated with this theme semester listed at: http://lsa.umich.edu/universe/events.asp.

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, 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.
