Exam 3 grades are UP, HW 12 ready

1. Exam 3 scores are now up. I was very happy to see some nice improvement.
   
2. HW 12 is running, and it requires some extra reading in chapter 13. It is due Monday, 3:30 PM.

If you want to read ahead, start scanning chapter 14 about entropy and heat engines. Hurricanes are enormous heat engines.

Have a great weekend.
