Gail:

This is really good. I've read the PDF, I haven't figured out how to play the audio/video yet.

Could you please advise how to pronounce your last name (Tverberg). Sometimes I refer to my sources when talking to someone, rather than in written communication, and I want to get it right. Your article is really clear and I want to tell people about it.

I say Tuh' ver berg. That's not really the original Norwegian pronunciation. I think that would be more like Tver' berg, with the r rolled.
