Still working on this. It's going to take a bit longer than a week.
No rush, Joe. I'm still trying to ease myself back into PD. I don't even know why I have to, I've been here for... Well, a long time. Suffice to say I consider Roger a personal friend, who I've spent one on one time with in person.
Also, Roger, sorry for making Boston boring, but glad I could work out the inscription on the monument. And thank you for the advice, I'm not done with either mathematics or physics yet.
