The history of pigments for the color blue was in a magazine I get.

In this case I learned about the square root of 2, and a few other things.<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Square-root-of-2-.jpg\" alt=\"\" width=\"240\" height=\"101\" class=\"alignright size-full wp-image-12916\" \/><br \/>\nThe number 1.414213562373095048801688 \u2026 is an approximate value for the square root of 2, but the digits just keep going on and on. Likewise, 3.1415926253 \u2026 is such a number (the ratio \u03c0 of a circle&#8217;s circumference to its diameter. Both are called irrational. The odd thing is that while the digits go on and on, it has a position on the number line.<br \/>\nYou can see how this is done here: {replace XXX with www}<br \/>\nhttps:\/\/XXX.youtube.com\/watch?v=2bMKu1CXyB0   <\/p>\n<p>Actually, I did do something. I read and watched videos about how my wood stove works and about proper maintenance. So, I have allowed it to cool.<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Flue-cap-not-mine-300x209.jpg\" alt=\"\" width=\"300\" height=\"209\" class=\"alignright size-medium wp-image-12915\" srcset=\"http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Flue-cap-not-mine-300x209.jpg 300w, http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Flue-cap-not-mine.jpg 680w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/>I cleaned the flue cap and its  protector wire mesh. This is a photo from the web, but it is the same model as mine. This one is about 97% covered with creosote.<br \/>\nYikes! I use a wire brush about every six weeks. If air can&#8217;t flow out, the stove won&#8217;t burn properly, or at all. The mesh keeps sparks from flying out, but it is also the coldest part, allowing the material to condense and cling to it.<br \/>\n I have ordered a brush to clean the flue (arriving Monday). The rest of the stove looks normal, although I will have to clean it after using the brush. I also ordered pipe cleaners to dust out the holes in the catalytic converter. I&#8217;ll do this without taking it out. Otherwise I need to replace a flimsy gasket around it.  (Next year, maybe.) The photo here shows one similar to mine with some of the passages clogged. This clogging reduces flow of hot gasses and its function because the &#8220;air&#8221; cannot touch the coating.<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Catalytic-combustor.jpg\" alt=\"\" width=\"692\" height=\"293\" class=\"aligncenter size-full wp-image-12914\" srcset=\"http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Catalytic-combustor.jpg 692w, http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Catalytic-combustor-300x127.jpg 300w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px\" \/><br \/>\nKeeping up with news: The US shot a balloon drifting over the North American continent. Those that paid attention got schooled on wind currents at 60,000 feet. This week there was rapidly moving cold air following the same path. Relatives in North Central Pennsylvania had a minus 1 this morning (Sat) at dawn. <img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Balloon-path-over-north-america.jpg\" alt=\"\" width=\"412\" height=\"240\" class=\"aligncenter size-full wp-image-12913\" srcset=\"http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Balloon-path-over-north-america.jpg 412w, http:\/\/rocknponderosa.com\/wp-content\/uploads\/2023\/02\/Balloon-path-over-north-america-300x175.jpg 300w\" sizes=\"auto, (max-width: 412px) 85vw, 412px\" \/><br \/>\nNext week we may learn what this was about.
