My little town in west Michigan (14,500 people) apparently doesn't want a king in our federal government.

Netflix really needs to commission new seasons of "The Hollow". Excellent animation. Quality story lines. Relatable characters. The only other North American animation series that I can't watch repeatably is "Kipo and the Age of Wonderbeasts".

Nope. I'm happy with our little library

I just discovered Son of a Critch while surfing Netflix. I like it. Good Canadian comedy filmed in my favorite Canadian province; Newfoundland and Labrador.

Check out the Discworld series by Terry Pratchett. The entire series is available as audiobooks. Also, my dog Lego says hello to what appears to be, his long lost cousin.

Science and Art was the combined theme of my Art Thesis at the end of my BFA which I did 30 years after I received my Geology Ph.D. Let me know if I can help. The attached image is the front side of the announcement postcard for my BFA defence.

For the bryozoan folks that I just followed. Thin section photomicrograph of the central portion of an Archimedes spire. Mississippian (lower Carboniferous) Hartselle Sandstone equivalent, Alabama, USA fov about 4mm

The combo stain works best for studying limestones in thin section. The blue of the potassium ferricyanide kicks in for ferroan carbonates and they really only occur in sedimentary rocks during diagenetic alteration. Here's an example, Fe-calcite fill of a gastropod mold. FOV about 3mm

Trump's plan to impose 25% tariffs is going to result in a lot of harm to not only the economies of Canada and Mexico, but also to the United States. But I suspect that has been his plan all along.

One of my earlier mixed glass and ceramic pieces. A not particularly realistic ammonite half pair with fused glass reprecenting calcite pore-filling cement. Originally 35 cm in diameter, one side was reduced to 20 cm and the other destroyed when I dropped the pair on a concrete floor. C'est la vie.

Multiple microbial colonies (Aphralysia anfracta) in thin section. Mississippian, Hartselle (Equivalent) Sandstone, Central Alabama. FOV approximately 1.2 cm. Kopaska-Merkel, Haywick and Keyes (2020)

I finally added a photo of myself to my profile and to celebrate this menial task, i present you with a lovely photograph of a Paleozoic bryozoan (probably Archimedes) in thin section.
Hartselle Sandstone (but not a sandstone), Mississippian, eastern Alabama, USA.

Kiln glass art meets paleontology. Scientific art by your's truly c 2015

And if anyone who has decided to follow me is interested, this is a thin section image of marine cement in Mississippian-aged microbial-rich limestones in Alabama. My current research focuses on microbial-sediment-diagenesis interactions in Paleozoic carbonates.
