A few of you haven't turned in contracts. This must be done today. You can print out a new copy from the web site.

Today at 3:15 in Seaver 111, Dr. Mark Moldwin will speak about Music of the Spheres: Using Geomagnetic Field-line Resonances to Remotely Sense Space Weather. What this translates to is the interaction between the earth's magnetic field and the solar winds. (And, yes, refreshments will be served.)

There is a problem due Wednesday.

For Monday, there is a worksheet due. This is on the material which is to be read for Monday- vectors (chapter 3) & two-dimensional motion (start of chapter 4).

Today we'll go through a few more exercises related to one-dimensional motion with constant acceleration.
