Matt Young @opticist.bsky.social · 23/09/2026We just ran a piece by Dan Phelps, Williamstown secret deal may get a free fire station for the Ark suggesting that the proprietors of the Ark Park in Kentucky may have discovered a new mechanism (I almost wrote scheme) for extracting funds from the government. pandasthumb.org/archives/202... 101
Matt Young @opticist.bsky.social · 06/09/20262nd place in the Panda's Thumb Photography Contest, by Al Denelsbeck. I posted the winner on July 29. The artifact on the right picture, which is shown in more detail on the Thumb, may be due to aliasing. See "alt" for more. The insect is *not* a mantis. pandasthumb.org/archives/202... 021
Matt Young @opticist.bsky.social · 06/09/2026John Harshman's picture of a common potoo, third place in the Panda's Thumb Photography Contest. Look closely; it is a bird. pandasthumb.org/archives/202... 000
Matt Young @opticist.bsky.social · 06/09/2026Splendid pictures of ichneumonid wasps by Malcolm Schongalla. Honorable Mention in Panda's Thumb Photography Contest. Wasps are on the same log, laying eggs on horntail larvae, which the wasp larvae will eat. Darwin found it disturbing. pandasthumb.org/archives/202... 000
Matt Young @opticist.bsky.social · 29/07/2026A piece by Daniel Phelps cross-posted from the blog Righting America, with a commentary by William Trollinger - shows how Kentucky taxpayers were taken for a ride, and not in an ark. The ark in the photo seems to be in drydock. pandasthumb.org/archives/202... 000
Matt Young @opticist.bsky.social · 29/07/2026Gert Korthof (biologist and proprietor of wasdarwinwrong.com) has won the XVI-th Panda's Thumb Photography Contest with this photo of a spider in its web, supplemented by 2 shots of a web illuminated by sunlight. The origin of the color is a mystery, at least to me. pandasthumb.org/archives/202... 010
Matt Young @opticist.bsky.social · 08/07/2026Panda's Thumb. Urophora cardui. A tomato I saw growing in a thistle (read the post!). And please do not forget the Panda's Thumb Photo Contest. Entries close next Monday at noon, MDT. pandasthumb.org/archives/202... 000
Matt Young @opticist.bsky.social · 05/07/2026Latest article on Panda's Thumb: "David Coppege makes it clear a refresher course is needed," by Joe Felsenstein. Coppege thinks he debunks natural selection. Yes, really. pandasthumb.org/archives/202... CC BY-SA 3.0. 130
Matt Young @opticist.bsky.social · 21/03/2026Panda's Thumb: Glenn Branch of NCSE reviewed "Evolution Is Wrong: A Radical Approach to the Origin & Transformation of Life," by Erich von Däniken, under the title, "He's Saying It Was Aliens ...

Matt Young @opticist.bsky.social · 02/01/2026Just ran a short piece, Measles at the Ark, by Dan Phelps, on Panda's Thumb. An unvaccinated person with measles visited the Ark Park, and authorities are warning the public. Phelps is "sad" that "anti-science" is putting people in real danger. So I am I. pandasthumb.org/archives/202... 020
Matt Young @opticist.bsky.social · 30/11/2025My biweekly photograph on Panda's Thumb -- a tiny (few millimeters) unidentified spider about to lunch on a box elder bug, Boisea trivittata. pandasthumb.org/archives/202...

Matt Young @opticist.bsky.social · 24/11/2025Post run on Panda's Thumb by Joe Felsenstein about what appears to be a completely unqualified academic who changed his mind (gasp!) and now rejects "Darwinism." pandasthumb.org/archives/202... 000
Matt Young @opticist.bsky.social · 24/11/2025My discussion of this book on evolution of organisms adapted to living in cities & towns. Author argues that cities & towns worldwide will ultimately have nearly identical floras & faunas. If they have gained a foothold, may we then plant exotic species deliberately? pandasthumb.org/archives/202... 052
Matt Young @opticist.bsky.social · 13/11/2025A nice shot of the aurora the other night by Vivian Dullien, which I posted on Panda's Thumb yesterday. Taken with her cell phone. pandasthumb.org/archives/202... 010

Matt Young @opticist.bsky.social · 19/08/2025Just ran a splendid pic by Al Denelsbeck showing how gingko leaf sheds water and directs it to the roots of the tree. It earned Honorable Mention in xvi-th (!) Panda's Thumb photo contest. pandasthumb.org/archives/202... 010
Matt Young @opticist.bsky.social · 18/08/2025I just posted a short article on The Panda's Thumb, musing upon the book On Being Certain: Believing You Are Right Even When You're Not, by Robert Burton.

Matt Young @opticist.bsky.social · 04/07/2025Astonishingly, 1 USian in 4 rejects evolution and so much modern science. The Scopes trial did not defeat creationism; it drove it dormant for a while. See my precis here pandasthumb.org/archives/202... and also a full post by William Trollinger and Susan Trollinger linked in the text. 000
Matt Young @opticist.bsky.social · 02/07/2025Just reposted an article by Glenn Branch, "How the Scopes Trial Was Almost Scooped" in 1922, on The Panda's Thumb, here: pandasthumb.org/archives/202.... The original had been posted a few days earlier on the Righting America blog. 010

Matt Young @opticist.bsky.social · 03/03/2025Went to a demonstration in front of Noaa/Nist in Boulder this noon (Mar 3). David Skaggs, for whom the Noaa building is named, gave a speech, but the speakers were too hard to hear. The panorama (you will have to click it) is maybe 1/3 to 1/2 of all the people. Finally, 2 of the more amusing signs. 031
Matt Young @opticist.bsky.social · 18/02/2025Just for fun, I posted a picture of 2 puffins on The Panda's Thumb blog, here pandasthumb.org/archives/202..., along with a poem from the book How to Tell the Birds from the Flowers, by the distinguished physicist R.W. Wood. Wood was perhaps better known as the author of the book Physical Optics. 000
