Diary: It's my homework and I need to do it, though I spend no time on it. It will be rough and may never be cleaned up, though I may extract a piece and give it its own post. The goal...just blog it.
8th - I watch a recording of the Olympic horse jumping. The announcer says that the red-yellow bar, rail, is being knocked down by several horses. She said, "It is as if they don't see it." In the record, I look at several of the different wood rails. They all look like burnt twigs. I have never looked at lumber before. It all looks like shriveled brunt wood, which I guess makes sense since most of the DEM in the wood was extracted in the drying process. I also look at other rails and realize that I can see them, but not as clearly as the top bright red-yellow rails. In the record, the yellow part of the rail has lead pigments in the paint to achieve the bright colors. With clairvoyant sight, the yellow middle part of the rail was barely visible compared to the red part. The horse's DEM vision does not see the middle part of the rail and assumes it is not there until they knock it down.
