The Physical World Galleries

Wood details : Closeups that reveal some of the fascinating character of wood, the uses it is put to, and the ways it interacts with the elements and with light. I've debated with myself about which category this subject belongs in. I've recently changed my mind and moved it from the Themes category to its present place in the Nature/The Physical World sub-category even though many of the pictures are of wood in a highly 'post-processed' manufactured state. Even then, it is the natural quality of the material, and in particular its grain and cell structure, and how it weathers when exposed to the elements that appeals to me (and, I hope, to viewers).

Geology, rocks, minerals : Pictures, from closeups to landscapes, that illustrate various aspects of geology and the nature of various minerals. Also pictures of rocks, boulders, pebbles, etc. of mixed, unknown, or uncertain composition that appealed to me. In a few cases, photos of manmade composites of interesting rocks or minerals. I could justify including almost every picture taken in some of the national and state parks of the western United States. However, I'll limit pictures from those places to ones that illustrate particular materials or processes. If you see photos here from places like the Grand Canyon, for example, there is almost certainly a separate gallery of mine (or more than one!) devoted to each such place. DISCLAIMER: I'm not a trained geologist, just a curious retired scientist (in a different field) with a strong interest in the natural world. If I have mis-stated any of the geologic information in my figure captions, the responsibility is mine, and I welcome any corrections or additions any of you might care to offer.
