Wait, puffins are in the PNW, too?! OK, guess I'll have to visit both places.

This Anthropic settlement caseโ€ฆfellow authors, are any of you feeling rage? I have 12 books listed and money (I donโ€™t CARE how many thousands, even millions) is NOT adequate compensation. What was stolen & used without my permission is priceless! Where is the option to scrub my work from AI?!

Knowing that a puffin colony is in the U.S. (Maine) impels me to go to Maine, because, you know, puffins, but also to see their burrows. Adding it now to my list of must-visit places... ๐Ÿงช๐Ÿฆ๐Ÿ•ณ๏ธ

My dear friend!
From now on, I apologize a thousand times for the long delay in my reply! You will, of course, laugh at me, perhaps even be angry with me, if I tell you what prevented me for so long from fulfilling this duty of friendship that I owed you: It wasn't that I wanted to avoid sharing my views on your theories with you; no, it was a geometric problem that had occupied me so intensely lately that it distracted me from everything I wanted to think and write and occupied me entirely. Several times I wanted to write down my views for you, but each time, after a few moments, instead of starting with a letter, I saw a geometric figure on the paper, which had drawn itself, almost without my knowledge or will.

Here's an excerpt from an 1841 letter from a scientist that I think pretty much any modern scientist can relate to.

Since #Croctober has just kicked off, here's an older illustration of the VERY distant relative to crocodilians, the Triassic archosaur Teleocrater. I made this illustration in 2019, just 2 years into my career, for the Field Museum of Natural History's Evolving Planet exhibition

Book cover for the Chinese edition of my book 'Life Sculpted,' published by Shanghai Scientific & Technological Education Publishing House in December 2024. Cover has the title in Chinese, but also includes English with "Life Sculpted" and "Anthony J. Martin." Cover image is a closeup view of a clam shell with small holes and branching tunnels from bioeorsion, and an out-of-focus beach sand is in the background.

Side note on the Chinese cover image of 'Life Sculpted': I'm sure it's a photograph & not AI, because the patterns in the shell are identical to borings made by sponges & bryozoans. Although I didn't have a "No AI!" clause in the original contract, I'll insist on them for all future books. ๐Ÿ“šโœ๏ธ

Get really into dinosaurs. That's my recommendation for a happier life. Each day, I get news like "Look at this big freak that used roam the Earth!" or "Ya know the big freak you already loved? Fossils show it was even more freakish!" and it's a blessing every time.

This digitally painted piece honors the survivor spirit of the coyote by tracing its lineage from the first cells of life to the animal trotting our landscapes today. Below the horizon, carefully chosen ancestors mark pivotal moments in adaptation, each contributing to the form and survivor we see today. Above the horizon, Coyote stands alert at the center, framed by both Denverโ€™s skyline and a mountain backdrop, symbols of their ability to thrive in cities as well as wilderness. Embedded in the ground are the skulls and bones of carnivores whose lineages ended long ago, emphasizing Coyoteโ€™s persistence in contrast.
