Announcements

• Invoice for course reader (pdf)
• Information on Los Alamos Dynamics Summer Program
  $7000-$10,000 from mid-June to mid-August (U.S. citizen)

Homework Guidelines

1. Homework is due in the BOX according to the Syllabus.
   You must turn in a hardcopy of your lab/homework during class -- in the BOX.
2. To receive full credit, you must:
   • Show your work -- you'll get no credit for answers without explanations.
   • Circle / Highlight your answers -- if we can't find your answers, we can't grade your assignment.
   • Use Proper Notation -- use the notation of the class e.g. subscript, superscript and definition symbol.
   • Write your name on each page legibly -- if we can't read your name, we can't grade your assignment.
   • Staple pages -- if pages go missing, we can't grade your assignment.
   • If you use any computation tool (e.g. MotionGenesis (Autolev), MATLAB, etc.)
     you must submit a computational file that includes both input commands and output results.
