As I announced in class we will have a make up lecture next week. It was my intention to have the make up lecture on Monday. However some students will be away doing experiments and will not be able to attend. For this reason the make up lecture will take place on **Friday 13th (!) in Rm 3110 ESB from 5 pm to 6:20 pm.**

The List of Suggested term papers was posted on Monday November 9. They are due on Wednesday December 16 in Rm 3110 ESB where the students will give their presentations.
