Over twenty-eight miles in just a little over two hours.\u00a0 I&#8217;m hoping I&#8217;ll get another long ride or two in before winter arrives, but if that&#8217;s my longest this year I&#8217;m satisfied.\u00a0 The days are short and it&#8217;s dark alot, so next time I&#8217;ll go for speed to see how far I can go in ninety minutes.<\/p>\n\n\n\n<p>Last Friday Jeannie and I went to see Branford Marsalis playing with his quartet at SUNY Purchase.&nbsp; They have a very nice concert hall there, although lots of little things about it are weird, including the entrance to the venue being in a tunnel, and the lack of a center aisle of doors in back means the entrance to the hall from the lobby is a little made of side hallways.&nbsp; Anyway the show was great.&nbsp; Branford is one of my favorite sax players around today.&nbsp; The piano player was Joey Calderazzo, who is amazing, and so were the rhythm section.&nbsp; The mainly band played an interoperation of the Keith Jarret album Belonging and to to some really great places.&nbsp;<\/p>\n\n\n\n<p>Saturday we went up to Boston for the OrigaMIT convention.&nbsp; The special guest was my friend John Montroll, who had never attended an OrigaMIT convention before, so that was a fun surprise.&nbsp; I also met his sister and nephew, who is a professor of mathematics and computer science.&nbsp; John gave a talk on his approach to origami design, which was very cool.&nbsp; His style of delivery is pretty breezy and laid back, so if you&#8217;re not paying attention you&#8217;ll miss how deep what alot of what he has to say is.<\/p>\n\n\n\n<p>I folded several new models for my exhibit.&nbsp; I taught my Platypus, so I did a new rendition of that out of purple tissue foil; it came out very nice.&nbsp; I also had a new version of my Lizard and Turtle, both folded out a sheet of beautiful hand-painted paper I bought in Venice, Italy when we were there a few years back.&nbsp; The other model I&#8217;ve been working on is a Dimpled Dodecahedron.&nbsp; I came up with a layout folded from a decagon that has polar symmetry.&nbsp; Back in July at the OUSA convention John helped me refine the layout to make the 3-D folding phase more tractable.&nbsp; It turns out to be a very difficult model to fold because as it accumulates layers inside that zigzag in strange ways and tend to push the model open like a budding flower.&nbsp; So most of the work I&#8217;ve been doing has been to manage the layers and make them organized and flat to mitigate that tendency.&nbsp; I got thru most of the southern hemisphere and am up to the lock at the south pole, where three tabs are supposed to go together in a pinwheel.&nbsp; Unfortunately, I didn&#8217;t quite have the worked out in time for the convention.&nbsp; I&#8217;m sort of in the Zeno&#8217;s paradox phase: every time I try, I get half the remaining distance to the finish line.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The weather continues to get colder and darker and stormier.\u00a0 Once it gets below forty degrees of so, biking gets more difficult, especially if it&#8217;s windy.\u00a0 So now I&#8217;m down to biking every other day or so, and when I go I gotta bundle up.\u00a0 A week ago I did my longest ride of the &hellip; <a href=\"https:\/\/www.zingman.com\/blog\/2025\/11\/18\/rollin-and-foldin\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;Rollin&#8217; and Foldin&#8217;&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7,15,19],"tags":[],"class_list":["post-6618","post","type-post","status-publish","format-standard","hentry","category-fitness","category-origami","category-travel"],"_links":{"self":[{"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/posts\/6618","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/comments?post=6618"}],"version-history":[{"count":4,"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/posts\/6618\/revisions"}],"predecessor-version":[{"id":6645,"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/posts\/6618\/revisions\/6645"}],"wp:attachment":[{"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/media?parent=6618"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/categories?post=6618"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zingman.com\/blog\/wp-json\/wp\/v2\/tags?post=6618"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
