Pi day pie extravaganza. Chicken pot pie and non-dairy raspberry chocolate custard. Nice way to celebrate the end of a good week.

About fifty years ago, NASA strapped a message in a bottle to a rocket and flung it into the deep dark
It wasn’t supposed to go this far, but it did. Long past its mission, it’s still out there so far away now that a simple hello takes a day to reach it, and another day to hear if it says hello back

Herman Melville's "Moby Dick" has perhaps the most memorable opening line in all of Western literature: "I hope you motherfuckers like reading about whales"

I feel like I do a lot of things pretty well, but there is nothing I do better than destroying the kitchen when I cook dinner.

They aren’t even good at picking examples. The above plot is a perfect example of CO2 control on the climate system and feedbacks that stem from rapid change.

Last post for #FossilFriday this lovely #Proterozoic #Acritarch because I love it so much. This image was taken with a macro lens at 2x attached to a microscope with a 100x mag lens. It's a combination of over 100 images stacked and stitched. #Geology #Paleontology

Beef Wellington pre-cook. I’m happy enough with this that even if it isn’t perfect, I’ll be ok with it.

As a former whitewater kayaker I can say that duck took an excellent line and hit his boof off that rock perfectly in what looks like solid class IV water. If I paddled that well I wouldn’t be a former kayaker.

800 g of mushrooms and 300 g of shallots cooks down pretty much to nothing. But oh what a nothing it is. It smells like heaven.

curry comb for a horse

curry comb for a horse

The pic is a curry comb. The name comes from the french word corroyer (older versions spelled differently that yielded curry). At least from what I have found, it translates to "prepare" or "make ready." As in to make your horse ready, not prepare your curry.

Artwork of a Stegosaurus gleefully bounding after a monarch butterfly. The Stegosaurus has orange and black patterning that matches the butterfly and the plates on its back look like monarch wings.

"Butterfly Effect" is by far my favorite piece I've ever drawn. I know I keep sharing it, but I just hope it brings joy when people see it.

(Plus I don't have a whole lot of new art to share.)
