Just got home from 4 days in the hospital so if I don't post for a couple of days, you'll know why. I'm exhausted. I swear, you cannot get a good night's sleep in a hospital. Someone is always poking you for something. Sure is good to be home and feeling better. Anyway, I hope to get some work done in the next couple of days and start pre-posting again. I took a great polymer class before I was laid up so I will post some photos of my interpretation.
