HW 13 re-run; HW 14 by noon Sat.

You can go back in on Homework 13 for more attempts on the calculations. Good for practice.

By the way, Homework 14, a big one, will be ready for everybody by noon Saturday, if not sooner. It will be due at the normal times in the morning for Sec. 0001 and in the afternoon for Sec. 0002.
