Physics 112 Started the section on mirrors (mirror_notes.pdf) by looking at how they differ conceptually from lenses. Check out the helpful online mirrors simulation: Once loaded, place the mouse over Applet Menu - then Optics - and finally Spherical Mirrors and Lenses - http://surendranath.tripod.com/Applets.html Physics 122 Notes and examples about problems with multiple masses. This week we will be working with the textbook: Read pages 478 - 489.  Problems pg 485 #s 19 - 23, pg 488 #s 24 - 28. Comp Sci 110 Start reading through the Unit 13 notes (we skipped unit 12).  Do the if...then practice on page six of the notes. When finished reading the notes start the unit 13 assignment (unit_13_assignment.pdf).
