Speaking of science writing and making more science accessible to lay people, check out my Dad's article at Luminous Landscape where he explains Why Is My 50mm Lens Equivalent to 80mm on a 35mm Camera and Why Is There More Depth-of-Field? And check out the comment he received:

Nathan Myhrvold: I think that Charles Johnson’s article on DOF and sensor issues is excellent and will inform the discussion of the relative merits of various sensors and cameras. It covers the basic optical facts very well. However, I think that there are some additional points that can help clarify the issue...

Yes, that Nathan Myhrvold. Apparently, he shares both Dad's love of nature photography and of physics. Dad was pretty happy to see such detailed and well-informed feedback. See what happens when you post interesting writing on-line? Cool things! and you might make an interesting new friend or two. Get a blog Dad.
