Thanks Slice! It's snowing again today and I'm hoping they cancel classes later so that I can stay home and concentrate on these articles. I started looking at them last night and felt like I was in waaaaay over my head! 
The irony here is that I chose a history degree because it was one of the degree programs that required the least amount of math and science. I eventually got my M.S. and Ed.D. in education. After running from math and science my whole life, it's coming back to haunt me since getting involved in the SW hobby. Yikes! 
Just because I keep reference material at hand doesn't mean I understand much of it. I try to pick out nuggets here and there that I can use. I will eventually circle back around and do in depth study on this stuff, but for now, I mostly just look at the pictures 
Some science interests me, certainly not physics or chemistry though. Luckily I never had to have much beyond college algebra and statistics....which I barely passed!
